Protection of the environment
General notes
Environmental note
H
Daimler's declared policy is one of integrated
environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an
environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear depend on
the following factors:
R
operating conditions of your vehicle
R
your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R
avoid short trips as these increase fuel
consumption.
R
always make sure that the tire pressures
are correct.
R
do not carry any unnecessary weight.
R
keep an eye on the vehicle's fuel
consumption.
R
remove roof racks once you no longer need
them.
R
a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R
always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R
do not depress the accelerator pedal when
starting the engine.
R
do not warm up the engine when the vehicle
is stationary.
R
drive carefully and maintain a safe distance
from the vehicle in front.
R
avoid frequent, sudden acceleration.
R
change gear in good time and use each gear
only up to Ô of its maximum engine speed.
R
switch off the engine in stationary traffic.
Environmental concerns and
recommendations
Wherever the operating instructions require
you to dispose of materials, first try to
regenerate or re-use them. Observe the
relevant environmental rules and regulations
when disposing of materials. In this way you
will help to protect the environment.
Product information
Mercedes-Benz recommends that you use
genuine Mercedes-Benz parts, conversion
parts and accessories that have been
approved for your vehicle.
Mercedes-Benz tests genuine parts as well as
conversion parts and accessories that have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benz is
unable to assess other parts. Therefore,
Mercedes-Benz accepts no responsibility for
the use of such parts in Mercedes-Benz
vehicles. This is also the case, even if they
have been independently or officially
approved. The use of non-approved parts
could affect your vehicle's operating safety.
Genuine Mercedes-Benz parts, approved
conversion parts and accessories are
available from any authorized Mercedes-Benz
Center. Here, you will receive advice about
permissible technical modifications, and the
parts will be professionally installed.

Sports UtilityVehicle
WARNING
G
This Sport Utility Vehicle is designed for both
on-road and off-road use. It can go places and
perform tasks for which conventional 2-wheel
drive passenger cars are not intended. This
vehicle will handle and maneuver differently
from conventional passenger cars in driving
conditions which may occur on streets,
highways and off-road use.
This vehicle has a higherground clearance
and a higher center of gravity than many
passenger cars. As with other vehicles of this
type, if you make sharp turns at excessive
speeds or abrupt maneuvers, the vehicle may
roll over or may go out of control and crash.
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
Failure to operate this vehicle safely may
resultinanaccident, rollover of the vehicle,
and severe or fatal injury.
Before you startto drive this vehicle, read the
Operator's Manual. Take time to become
familiar with the driving characteristics of this
vehicle. Be sure you are familiar with all
vehicle controls. Learn how your vehicle
handles on different road surfaces. Do not
attempt sharp turns at excessive speeds or
abrupt maneuvers or other unsafe driving
actions that can cause loss of vehicle control.
When driving off-road or working the vehicle
hard, do not overload it. And, always wear
your seat belts at all times. In a rollover crash,
an unbelted person is significantly more likely
to die than a person wearing a seat belt.
Operating safety
Important safety notes
WARNING
G
Work improperly carried out on electronic
components and associated software could
cause them to cease functioning. Because the
vehicle's electronic components are
interconnected, any modifications made may
produce an undesired effect on other
systems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
Contact an authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function when the
engine is running. You should therefore never
turn off the engine while driving.
WARNING
G
Heavy blows against the vehicle underbody or
tires/wheels may cause serious damage and
impair the operating safety of your vehicle.
Such blows can be caused, for example, by
running over an obstacle, road debris or a
pothole.
If you feel a sudden significant vibration or
ride disturbance, or you suspect that damage
to your vehicle has occurred:
R
turn on your hazard warning flashers.
R
slow down carefully.
R
drive with caution to an area which is a safe
distance from the road.
Inspect the vehicle underbody and tires/
wheels for possible damage. If the vehicle
appears unsafe, have it towed to the nearest
authorized Mercedes-Benz Center or other

Important safety notes
WARNING
G
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systemsno longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
In this section, you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint system consists of:

6 SRS warning lamp
R
Air bags
R
The air bag control unit with crash sensors
R
Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear
R
Belt force limiters
SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS warning lamp
WARNING
G
The SRS self-checkhas detected a
malfunction if the 6 SRS indicator lamp:
R
does notlight up at all
R
does not go out after approximately four
seconds after the engine is started
R
lights up after the engineis started or while
the vehicle is in motion
For your safety, Mercedes-Benz strongly
recommends that you have the system
checked as soon as possible at a qualified
specialist workshop. SRS may otherwise fail
to activate when it is needed in the event of
an accident, which could lead to serious or
fatal injuries. SRS might also be activated
unexpectedly and unnecessarily, which could
also result in injury.
In addition, work carried out improperly on
SRS may render SRS inoperative or cause
unintended air bag deployment. Work on the
SRS system should only be carried out by
qualified specialist personnel. Consult a
qualified specialist workshop.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact an authorized Mercedes-Benz Center
for details. USA only: for further information,
contact our Customer Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372).
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started.
The SRS components are in operational
readiness when the 6 SRS warning lamp
goes out while the engine is running.
Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags
WARNING
G
R
Damaged seat belts or seat belts that have
been subjected to stress in an accident
must be replaced. Their anchoring points
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-Benz Center.
R
Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the
environment.Check your national disposal
guidelines. California residents, see
www.dtsc.ca.gov/HazardousWaste/

Keep area between air bags and occupants
free of objects (e.g. packages, purses,
umbrellas, etc.).
R
Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may be thrown around in
the vehicle and cause head and other
injuries when the window curtain air bag is
deployed.
R
Air bag system components will be hot after
an air bag has inflated. Do not touch them.
R
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R
Improper repair work on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must therefore only be
performed by qualified technicians.
Contact an authorized Mercedes-Benz
Center.
R
For your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available
from any authorized Mercedes-Benz
Center.
R
Given the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.
If you sell your vehicle, Mercedes-Benz
strongly recommends that you inform the
subsequent owner that the vehicle is
equipped with SRS. Also, refer them to the
applicable section in the Operator's Manual.
Air bags
Important safety notes
WARNING
G
Air bags are designed to reduce the incidence
of injuries and fatalities in certain situations:
R
frontal impacts (driver's and frontpassenger front air bags and driver's knee
bag)
R
side impacts (side impact air bags and
window curtain air bags)
R
rollover (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.
When the air bags are deployed, a small
amount of powder is released. The powder
generally does not constitute a health hazard
and does not indicate that there is a fire in the
vehicle. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. If you
have any breathing difficulty but cannot get
out of the vehicle after the air bag inflates,
then get fresh air by opening a window or
door.
WARNING
G
In order to reduce the potential danger of
injuries caused during the deployment of the
front air bags, the driver and front passenger
Occupant safety
45
must always be correctly seated and wear
their seat belts.
For maximum protection in the event of a
collision, you must always be in the normal
seat position with yourback against the
backrest. Fastenyour seat belt and make sure
that it is correctly positioned on your body.
As the air bag inflates with considerable
speed and force, a proper seating position
and correct positioning of the hands on the
steering wheel will help to keep you at a safe
distance from the air bag. Occupants who are
not wearing their seat belt, are not seated
properly or are too close to the air bag can be
seriously injured or killed by an air bag, as it
inflates with great force instantaneously:
R
sit with the seat belt fastened correctly and
in a position that is as upright as possible
with your back against the backrest.
R
move the driver's seat as far back as
possible, still permitting proper operation
of vehicle controls. The distance from the
center of the driver's chest to the center of
the air bag cover on the steering wheel
must be at least 10 inches (25 cm). You
should be able to accomplish this by
adjusting the seat and steering wheel. If
you have any difficulties, please contact an
authorized Mercedes-Benz Center.
R
do not lean your head or chest close to the
steering wheel or dashboard.
R
only hold the steering wheel on the outside.
Placing hands and arms inside the rim can
increase the risk and potential severity of
hand/arm injury if the driver front air bag
inflates.
R
adjust the front-passenger seat as far back
as possible from the dashboard when the
seat is occupied.
R
occupants, especially children, should
never place their bodies or lean their heads
in the area of the door where the side
impact air bag inflates. This could result in
serious or fatal injuries should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt
properly and use an appropriately sized
infant restraint, toddler restraint or booster
seat recommended for the size and weight
of the child.
Failure to follow these instructions can result
in severe injuries to you or other occupants.
If you sell your vehicle, it is important that you
make the buyer aware of this safety
information. Be sure to give the buyer this
Operator's Manual.
WARNING
G
Accident research shows that the safest place
for children in an automobile is in a rear seat.
Aside impact air bag related injury may occur
if occupants, especially children, are not
properly seated or restrainedwhen next to a
side impact air bag which needs to deploy
rapidly in a side impact in order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Always sit as upright as possible
and use the seat belts properly.
Make sure that children 12 years
old and under use an appropriately
sized child restraint, infant
restraint, or booster seat
recommended for the size and
weight of the child.
(2) Always wear seat belts properly.
If the air bags are deployed, you will hear a
bang, and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6 SRS warning lamp
lights up.
The air bags are deployed if the air bag control
unit detects the need for deployment. Only in
the event of such a situation will the air bags
provide their supplemental protection.
If the driver and front passenger do not wear
their seat belts, it is not possible for the air
bags to provide their supplemental
protection.
Safety
Z
Occupant safety
46
In the event of other types of impacts and
impacts below air bag deployment
thresholds, the air bags will not deploy. The
driver and passengers will then be protected
to the extent possible by a properly fastened
seat belt. Aproperly fastened seat beltis also
needed to provide the best possible
protection in a rollover.
Safety
Air bags provide additional protection; they
are not, however, a substitute for seat belts.
All vehicle occupants must fasten their seat
belts regardless of whether your vehicle is
equipped with air bags or not.
It is important for your safety and that of your
passengers to have deployed air bags
replaced and to have any malfunctioning air
bags repaired. This will help to make sure the
air bags continue to perform their protective
function for the vehicle occupants in the
event of a crash.
Front air bags
Driver's air bag : deploys in front of the
steering wheel; front-passenger front air
bag ; deploys in front of and above the glove
box.
The front air bags increase protection for the
driver's and front-passenger's head and
chest.
They are deployed:
R
in the event of certain frontal impacts
R
if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R
depending on whether the seat belt is being
used
R
independently of other air bags in the
vehicle
If the vehicle overturns, the front air bags are
generally not deployed. If the system detects
high vehicle deceleration in alongitudinal
direction, the front air bags are deployed.
When a child restraint system is installed on
the front-passenger seat and the 4
PASSENGER AIRBAG OFF indicator lamp in
the center console does not light up:
R
a child restraint system without a
transponder for the air bag deactivation
system is installed or
R
a child restraint system with a transponder
has not been installed properly.
Your vehicle has adaptive, two-stage front air
bags. In the event of a collision, the air bag
control unit evaluates the vehicle
deceleration. In the first deployment stage,
the front air bag is filled with enough
propellant gas to reduce the risk of injuries.
The front air bag is fully deployed if a second
deployment threshold is exceeded within a
few milliseconds.
The deployment of front-passenger front air
bag ; is also influenced by the weight
category of the front passenger, which is
determined by the Occupant Classification
System (OCS) (Y page 48).
The lighter the passenger side occupant, the
higher the vehicle deceleration rate required
(predicted at the start of the impact) for
second-stage inflation of the front-passenger
front air bag. In the second stage, the front
air bags are inflated with the maximum
amount of propellant gas available.
The front air bags are not deployed in
situations where a low impact severity is
predicted. You will then be protected by the
fastened seat belt.
Occupant safety
47
Front-passenger front air bag ; will only
deploy if:
R
the system, based on the OCS weight
sensorreadings, has detected that the
front-passenger seat is occupied.
R
the 45 indicator lamp on the center
console is not lit (Y page 48).
R
the air bag control unit predicts a high
impact severity.
Driver's knee bag
Driver's knee bag : deploys under the
steering column. The driver's knee bag is
always deployed along with the driver's front
air bag. The driver's knee bag is designed to
operate together with the frontair bags in
frontal impacts if certain thresholds are
exceeded. The driver's knee bag operates
best in conjunction with correctly positioned
and fastened seat belts.
The driver's knee bag increases protection of
the driveragainst:
R
knee injuries
R
thigh injuries
R
lower leg injuries
Side impact air bags
WARNING
G
Only use seat covers which have been tested
and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the side impact air bags. Contact an
authorized Mercedes-Benz Center for
availability.
WARNING
G
The pressure sensors for side impact air bag
control are located in the doors. Do not
modify any components of the doors or door
trim panels including, for example, the
addition of door speakers.
Improper repair work on the doors or the
modification or addition of components to the
doors create a risk of rendering the side
impact air bags inoperative or causing
unintended air bag deployment. Work on the
doors must therefore only be performed by
qualified technicians. Contact an authorized
Mercedes-Benz Center.
Frontside impactair bags : and side impact
air bags in the 2nd row of seats ; inflate next

R
the front-passenger seat belt is not
fastened.
The side impact air bag on the frontpassenger side will deploy if the frontpassenger seat belt is fastened, regardless of
whether the front-passenger seat is occupied
or not.
Window curtain air bags
Window curtain air bags : enhance the level
of protection for the head, but not chest or
arms, of the vehicle occupants on the side of
the vehicle on which the impact occurs.
The window curtain air bags are integrated
into the side of the roof frame and deploy in
the area from the A-pillar to the C-pillar.

passenger seatis classified as being empty.
When the OCS senses that the front
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 45 indicator lamp will
illuminate when the engine is started and
remain illuminated. This indicates that the
front passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat is classified as being empty,
the 45 indicator lamp will illuminate
when the engine is started and remain
illuminated. This indicates that the front
passenger front air bag is deactivated.
When the OCS senses that the front
passenger seat occupant is classified as
being heavier than the weight of a typical 12month-old child seated in astandard child
restraint or as being a small individual (such
as a young teenager or asmall adult), the
45 indicator lamp will illuminate for
approximately 6seconds when the engine is
started. Depending on occupant weight
sensor readings from the seat, it will then
remain illuminated or go out. With the
45 indicator lamp illuminated, the
frontpassenger frontair bag is deactivated.
With the 45 indicator lamp out, the

WARNING
G
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriate infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and Top Tether strap, or lower anchors
and Top Tether strap, fully in accordance with
the child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.

Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the frontpassenger seat:
R
Your vehicle is equipped with air bag
technology designed to deactivate the
front-passenger frontair bag in your vehicle
Safety
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front-passengerseat.
R
Achild in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to eliminate
this risk completely is never to place a child
in a rear-facing child restraint in the frontpassenger seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint on the rear
seat.
R
If you install a rear-facing child restraint on
the front-passenger seat, make sure the
45 indicator lamp is illuminated,
indicating that the front-passenger front air
bag is deactivated. Should the 45
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
45 indicator lamp while driving to
make sure that the 45 indicator
lamp is illuminated. If the 45
indicator lamp goes out or remains out, do
not transport a child on the front-passenger
seat until the system has been repaired.
Achild in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates.
R
If you place a child in a forward-facing child
restraint on the front-passenger seat:
-
move the seat as far back as possible
-
use the proper child restraint
recommended for the age, size and
weight of the child
-
secure child restraint with the vehicle's
seat belt according to the child seat
manufacturer's instructions
R
For children larger than the typical 12month-old child, the front-passenger front
air bag may or may not be activated.
WARNING
G
If the red 6 SRS warning lamp in the
instrument cluster and the 45
indicator lamp light up simultaneously, the
OCS is malfunctioning. The front passenger
front air bag will be deactivated in this case.
Have the system checked by qualified
technicians as soon as possible. Contact an

PRE-SAFE®(anticipatory occupant
protection system)
WARNING
G
The PRE-SAFE®system reduces the impact of
an accident on vehicle occupants, as long as
their seat belts have been fastened correctly.
Although your vehicle is equipped with a PRE-
Safety
SAFE®system, the possibility of injury in the
event of an accident cannot be ruled out. You
should therefore always drive carefully and
adapt your driving style to the prevailing road,
weather and traffic conditions.
WARNING
G
Make sure that nobody can become trapped
as you adjust the seat.
!
Make sure that there are no objects in the
footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
PRE-SAFE®takes preemptive measures to
protect occupants in certain hazardous
situations.
PRE-SAFE®intervenes:
R
if BAS intervenes, e.g. in emergency
braking situations
R
if BAS PLUS intervenes powerfully — on
vehicles with DISTRONIC PLUS
R
if, on vehicles with DISTRONIC PLUS, the
radar sensor system detectsanimminent
dangerofcollision in certain situations
R
in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely
PRE-SAFE®takes the following measures
depending on the hazardous situation
detected:
R
the front seat belts are pre-tensioned.
R
vehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavorable position.
R
vehicles with a multicontour seat: the air
pressure in the side bolsters of the seat
backrest is increased.
R
if the vehicle skids, the sliding sunroof/
panorama roof with power tilt/sliding
panel and the side windows are closed so
that only a small gap remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE®slackens
the belt pretensioning. In vehicles with
multicontour seats, the air pressure in the
side bolsters is reduced again. All settings
made by PRE-SAFE®can then be reversed.
If the seat belts are not released:
X
Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism is released.

Seat belts
Important safety notes
WARNING
G
Always fasten your seat belt before driving off.
Always make sure all of your passengers are
properly restrained. You and your passengers
should always wear seat belts.
Failure to wear and properly fasten and
position your seat belt greatly increases your
risk of injuries and their likely severity in an
accident.
If you are ever in an accident, your injuries can
be considerably more severe without your
seat belt properly buckled. Without your seat
belt buckled, you are much more likely to hit
the interior of the vehicle or be ejected from
it. You can be seriously injured or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. The air bags can only protect
Occupant safety
55
as intended if the occupants are properly
wearing their seat belts.
WARNING
G
Never ride in a moving vehicle with the seat
backrestinanexcessively reclined position as
this can be dangerous. You could slide under
the seatbelt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck.That could cause serious
or even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the seat belt is properly
positioned on the body.
WARNING
G
Never let more people ride in the vehicle than
there are seat belts available. Make sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at a
time.
WARNING
G
Always have damaged seat belts or seat belts
that have been subjected to a load in an
accident replaced and the anchorages
checked.
Only use seat belts that have been approved
by Mercedes-Benz.
Never tamper with seat belts. This can result
in the unintended deployment of the
Emergency Tensioning Devices or the failure
to deploy when necessary.
Do not bleach or dye seat belts, as this may
severely weaken them. In the event of a
collision, they may be unable to provide
adequate protection.
Have all work carried out only by qualified
technicians. Consult a qualified specialist
workshop.
The use of seat belts and infant and child
restraint systems is required by law in:
R
all 50 states
R
U.S. territories
R
the DistrictofColumbia
R
all Canadianprovinces
Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey.

See "Children in the vehicle"
(Y page 60) for further information on
infants and children traveling in the vehicle
as well as on child restraint systems.
Correct use of the seat belts
WARNING
G
USE SEAT BELTS PROPERLY
R
Seat belts can only work when used
properly.Never wear seat belts in any other
way than as described in this section, as
that could result in serious injuries in the
event of an accident.
R
Each occupant should wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver frontair bag, driver's side knee
bag, front-passengerfront air bag, side
impact air bags, window curtain air bags for
the side windows), Emergency Tensioning
Devices, seat belt force limiters, and front
seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags,
driver's side knee bag and ETDs) and side
(side impact air bags, windowcurtain air
bags, and ETDs) impacts which exceed
preset deploymentthresholds and in
certain rollovers (window curtain air bags
and ETDs).
R
Never wear the shoulder belt under your
arm, across your neck or off your shoulder.

In a frontal crash, yourbody would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder

section is located as close as possible to
the middle of the shoulder. It should not
touch the neck.Never pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet.
R
Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
abdomen, it could cause serious injuries in
a crash.
R
Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
R
Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
R
Never use a seat belt for more than one
person at a time. Do not fasten a seat belt
around a person and another person or
other objects at the same time.
R
Seat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distributeimpact forces.
The twisted seat belt against yourbody
could cause injuries.
R
Pregnant women should also always use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
R
Place the seat backrest in a position that is
as upright as possible.
R
Check your seat belt during travel to make
sure it is properly positioned.
R
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
R
When using a seat belt to secure infant
restraints, toddler restraints, or children in
booster seats, always follow the child seat
manufacturer's instructions.
WARNING
G
Do not pass seat belts over sharp edges. They
could tear.
Do not allow the seat belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the seat belt.
Never attempt to make modifications to seat
belts. This could impair the effectiveness of
the seat belts.
Fastening seat belts
WARNING
G
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child. For additional information, see the

Belt warning for the driver and front
passenger
Regardless of whether the driver's and frontpassenger seat belts have already been
fastened, the 7 seat belt warning lamp
lights up for six seconds each time the engine
is started. It then goes out if the driver and
the front passenger have fastened their seat
belts.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. The warning tone goes out
after approximately six seconds or once the
driver's seat belt is fastened.
If after six seconds the driver or front
passenger have not fastened their seat belts
and the doors are closed, the 7 seat belt
warning lamp lights up:
R
until the driver's or front passenger's seat
belt is fastened
R
if a vehicle speed of 15 mph (25 km/h) is
exceeded, a warning tone also sounds with
increasing intensity for a maximum of
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver/front passenger unfasten their
seat belt while the vehicle is in motion, the
7 seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases even if the driver or
front passenger have still not fastened their
seat belt after 60 seconds. The 7 seat belt
warning lamp stops flashing but remains
illuminated.
After the vehicle comes to a standstill, the
warning tone is reactivated and the 7 seat
belt warning lamp flashes again if the vehicle
speed again exceeds 15 mph (25 km/h).
The 7 seat belt warning lamp only goes
out if:
R
both the driver and the front passenger
have fastened their seat belts.
or
R
the vehicle is stationary and a door is open.

WARNING
G
Pyrotechnic Emergency Tensioning Devices
that have been deployed must be renewed.
For your safety, when disposing of Emergency
Tensioning Devices, always observe the
safety instructions. These are available from
any authorized Mercedes-BenzCenter.
The PRE-SAFE®system has electrically
operated reversible pre-tensioners that do
not require replacement after activation.
!
If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the frontpassenger seat. Otherwise, the Emergency
Tensioning Device could be triggered in the
event of an accident.
X
In order to ensure that the pyrotechnic
Emergency Tensioning Devices have not
been triggered, always have the seat belts
checked after an accident.
If the Emergency Tensioning Devices have
been triggered, they must be replaced.
The frontseat belts and the outer seat belts
in the rear are equipped with Emergency
Tensioning Devices and belt force limiters.
The ETDs on the driver's and front-passenger
seat consist of pyrotechnic belt buckle
tensioners and belt anchor tensioners that
are triggered together. The belt buckle
tensioner is mounted on the B-pillar and the
belt anchor installing is mounted on the side
of the seat. After deploying, both tensioners
must always be replaced.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
When triggered, seat belt force limiters help
to reduce the peak forceexerted by the seat
belt on the vehicle occupant.
The belt force limiters for the front seats are
synchronized with the front airbags, which
take on a part of the deceleration force. This
results in the force exerted on the occupant
being distributed overagreater area.
The ETDs can only be activated when:
R
the ignition is switched on.
R
the restraint systems are operational; see
"SRS warning lamp" (Y page 43).
R
the belt tongue is engaged in the buckle on
each of the lap-shoulder belts in the front.
R
the front-passenger seat is occupied and
the belt tongue is engaged in the buckle on
the front-passenger side
The ETDs on the outside seats in the rear
compartment are triggered independently of
the lock status of the seat belts.
The ETDs are triggered depending on the type
and severity of an accident:
R
if, in the event of a head-on or rear-end
collision, the vehicle decelerates or
accelerates rapidly in a longitudinal
direction during the initial stages of the
impact
R
if, in the event of a side impact, on the side
opposite the impact the vehicle
decelerates or accelerates rapidly in a
lateral direction
R
if, in certain situations where the vehicle
overturns, the system determines that it
can provide additional protection
If the ETDs are deployed, you will hear a bang,
and a small amount of powder may also be
released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6 SRS warning lamp

WARNING
G
According to accident statistics, children are
saferwhen properly restrained in the rear
Safety
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front
passenger seat:
R
Your vehicle is equipped with air bag
technology designed to deactivate the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front passenger seat.
R
For children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be activated.
Always make sure the 45indicator
lamp is illuminated, indicating that the front
passenger front air bag is deactivated.
R
Achild in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to
completely eliminate this risk is to never
place a child in a rear-facing child restraint
in the front seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint in a backseat.
R
If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 45indicator
lamp is illuminated, indicating that the front
passenger front air bag is deactivated.
Should the 45indicator lamp not
illuminate or go out while the restraint is
installed, please checkinstallation.
Periodically check the 45indicator
lamp while driving to make sure the 4
5 indicator lamp is illuminated. If the
45indicator lamp goes out or
remains out, do not transport a child on the
front passenger seat until the system has
been repaired.
Achild in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates.
R
If you have to place a child in a forwardfacing child restraint on the front passenger
seat, move the seat as far back as possible,
use the proper child restraint
recommended for the age, size and weight
of the child, and secure child restraint with
the vehicle's seat belt according to the
child seat manufacturer's instructions.
WARNING
G
If the child restraint system is not fitted
correctly on a suitable seat, it may not fulfil
its protective function. In the event of an
accident, sharp braking or a sudden change
Children in the vehicle
61
in direction, the child may not be held
securely. The child could thus be seriously or
even fatally injured. For this reason, when
fitting a child restraint system, observe the
manufacturer's installation instructions and
the correct use of the child restraint system.
Child restraint systems should preferably be
fitted on the rear seats.The child is generally
better protected there.
The entire base of the child restraint system
must always rest on the seat cushion.
Therefore, never place objects, e.g. a cushion,
under the child restraint system.
Only use child restraint systems with the
original cover designed for them. Only replace
damaged covers with genuine covers.
We recommend that you use the child
restraint systems which have been
recommended for Mercedes-Benz.
WARNING
G
Infants and small children should never share
a seat belt with another occupant. In the event
of an accident, they could be crushed
between the occupant and seat belt.
Achild's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position the shoulder belt across the chest
and shoulder, not face or neck.Abooster seat
may be necessary to achieve proper seat belt
positioning for children over 41 lb (18 kg) until
they reach a height where a lap-shoulder belt
fits properly without a booster.
When the child restraint is not in use, remove
it from the vehicle or secure it with the seat
belt to prevent the child restraint from
becoming a projectile in the event of an
accident.
WARNING
G
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. Achild's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could:
R
injure themselves on parts of the vehicle
R
be seriously or fatally injured through
excessive exposure to extreme heat or cold
R
injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
ignition lock or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts.

Drive on carefully. Have ABS checked
immediately at a qualified specialist
workshop.
Important safety notes
If you fail to adapt your driving style or
become distracted, the driving safety
Safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road and weather
conditions and maintain asafe distance from
the vehicle in front. Drive carefully.
i
The driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Please pay special
attention to the noteson tires,
recommended minimumtire tread depths,
etc. (Y page 398).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible.
ABS (Anti-lock Braking System)
Important safety notes
i
Observe the "Importantsafety notes"
section(Ypage 66).
WARNING
G
If ABSis faulty, the wheels could lock when
braking. The steerability and braking
characteristics may be severely impaired.
Additionally, further driving safety systems
are deactivated. There is an increased danger
of skidding and accidents.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp (Y page 318) and
display messages which may be shown in the
instrument cluster (Y page 283).
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
ABS works from a speed of about 5 mph
(8 km/h) upwards, regardless of road-surface
conditions. ABS works on slippery surfaces,
even if you only brake gently.
The yellow ! ABS warning lamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is
running.
Braking
X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking
situation is over.
X
To make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
The pulsating brake pedal can be an
indication of hazardous road conditions, and
functions as a reminder to take extra care
while driving.
Off-road ABS
An ABS system specifically suited to off-road
terrain is activated automatically once the offroad program is activated on:
R
vehicles without the ON&OFFROAD
package (Y page 248)
R
vehicles with the ON&OFFROAD package
(Y page 248)
Driving safety systems
67
At speeds below 20 mph (30 km/h), the front
wheels lock cyclically during braking.The
digging-in effect achieved in the process
reduces the stopping distance on off-road
terrain. This limits steering capability.
BAS (Brake Assist System)
i
Observe the "Important safety notes"
section (Y page 66).
WARNING
G
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
BAS PLUS (Brake Assist System
PLUS)
i
Observe the "Important safety notes"
section (Y page 66).
BAS PLUS is only available in vehicles
equipped with DISTRONIC PLUS.
For BAS PLUS to assist you when driving, the
radar sensor system must be:
R
activated (Y page 277)
R
operational
With the help of the radar sensor system, BAS
PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time.
If the radar sensor system is malfunctioning,
BAS PLUS will not be available. The brake
system is still available with complete brake
boosting effect and BAS.
BAS PLUS provides braking assistance in
hazardous situations at speeds greater than
4 mph (7 km/h).
At speeds of up to approximately 40 mph
(70 km/h), BAS PLUS can also detect
stationary objects. Examples of stationary
objects are stopped or parked vehicles.
To prevent a front-end collision, BAS PLUS
calculates the brake force necessary if:
R
you approach an obstacle, and
R
BAS PLUS has detected arisk of collision
At aspeedless than 20 mph(30 km/h): if
you depress the brake pedal, BASPLUS is
activated. The increase in brake pressure will
be carried out at the last possible moment.
At a speed greater than 20 mph
(30 km/h):ifyou depress the brake pedal
sharply, BAS PLUS automatically raises the
brake pressure to a value adapted to the
traffic situation.
If BAS PLUS demands particularly high
braking force, preventative passenger
protection measures (PRE-SAFE®) are
activated simultaneously.
X
Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes
function as usual, if:
R
you release the brake pedal.
R
there is no longer any danger of a rear-end
collision.
R
no obstacle is detected in front of your
vehicle.
If you have activated DSR (Y page 246), BAS
PLUS is likewise deactivated.
WARNING
G
BAS PLUS cannot always clearly identify
objects and complex traffic situations. BAS
PLUS cannot intervene in these cases. There
is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.

Following damage to the frontend of the
vehicle, have the configurationand operation
of the radarsensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the frontofthe vehicle.
COLLISION PREVENTION ASSIST
General notes
COLLISION PREVENTION ASSIST consists of
Adaptive Brake Assist and the distance
warning function, which are described in the
following.
Distance warning function
Important safety notes
i
Observe the "Important safety notes"
section (Y page 66).
WARNING
G
The distance warning function does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
Thus, the distance warning function cannot
provide a warning in all critical situations.
There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
The distance warning function cannot always
clearly identify objects and complex traffic
situations.
In such cases, the distance warning function
may:
R
give an unnecessary warning
R
not give a warning
Always pay careful attention to the traffic
situation and do not rely solely on the
distance warning function.
Function
X
To activate/deactivate: activate or
deactivate the distance warning function in
the on-board computer (Y page 272).
When the distance warning function is
activated, the multifunction display shows
the Ä symbol, as long as the HOLD
function is not switched on (Y page 207). On
vehicles with Active Parking Assist, the
Ä symbol is displayed when P is engaged
or you are driving faster than 22 mph
(35 km/h).
The distance warning function can help you
to minimize the risk of a front-end collision
with a vehicle ahead or reduce the effects of
such a collision. If the distance warning
function detects that there is a risk of a
collision, you will be warned visually and
acoustically.The distance warning function
cannot prevent a collision without your
intervention.
Starting at a speed of around 20 mph
(30 km/h), this function warns you if you
rapidly approach a vehicle in front.An
intermittentwarning tone will then sound and
the · distance warning lamp will light up
in the instrument cluster.
X
Brake immediately in order to increase the
distance from the vehicle in front.
or
X
Take evasive action, provideditis safe to
do so.
For the distance warning function to assist
you when driving, the function must be
activated in the on-board computer and be
operational (Y page 272).
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display unnecessary warnings.
With the help of the radar sensor system, the
distance warning function can detect
obstacles that are in the path of your vehicle
for an extended period of time.
At speeds up to 40 mph (70 km/h), the
distance warning function may also detect
stationary obstacles, for example stopped or
parked vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision,
the system will initially alert you both visually
and acoustically.
In particular, the detection of obstacles can
be impaired if:
R
there is dirt on the sensors or anything else
covering the sensors
R
snow or heavy rain
R
interference by other radar sources
R
there are strong radar reflections, for

Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
Adaptive Brake Assist
i
Observe the "Important safety notes"
section (Y page 66).
WARNING
G
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic
situations. In these cases, Adaptive Brake
Assist may not intervene. There is a risk of an

deployed simultaneously.
Up to vehicle speeds of around 155 mph
(250 km/h), adaptive Brake Assist is capable
of reacting to moving objects that have
already been recognized as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due
to a malfunction in the radar sensor system,
the brake system remains available with full
brake boosting effect and BAS.
In particular, the detection of obstacles can
be impaired if there is:
R
dirt on the sensors or anything else

vehicle, have the configuration and operation
of the radar sensor checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
ESP®(Electronic Stability Program)
General notes
i
Observe the "Important safety notes"
section (Y page 66).
ESP®monitors driving stability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP®detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engine output is also modified to
keep the vehicle on the desired course within
physical limits. ESP®assists the driver when
pulling away on wet or slippery roads. ESP
®
can also stabilize the vehicle during braking.
ETS/4ETS (Electronic Traction System)
ETS/4ETS traction control is part of ESP®.
Traction control brakes the drive wheels
individually if they spin. This enables you to
pull away and accelerate on slippery surfaces,
for example if the road surface is slippery on
one side. In addition, more drive torque is
transferred to the wheel or wheels with
traction.
Traction control remains active, even if you
deactivate ESP®.

EBD (electronic brake force
distribution)
i
Observe the "Important safety notes"
section (Y page 66).
WARNING
G
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
Observe information regarding indicator and
warning lamps (Y page 319) as well as
display messages (Y page 285).
EBD monitors and controls the brake

significantly accelerate, automatic braking
may be performed up to alevel of automatic
emergency braking. Automatic emergency
braking is not performed until immediately
prior to an accident that can no longer be
avoided.
WARNING
G
PRE-SAFE®Brake will initially brake your
vehicle by a partial application of the brakes
if a danger of collision is detected. There may
be a collision unless you also brake.
Automatic emergency brakingcannot prevent
a collision.There is a risk of an accident.
Always apply the brakes yourself and try to
take evasive action.
WARNING
G
PRE-SAFE®Brake cannot always clearly
identify objects and complex traffic
conditions.
In these cases, PRE-SAFE®Brake may:
R
give an unnecessary warning and then
brake the vehicle
R
not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and be ready to brake, especially if
PRE-SAFE®Brake warns you. Terminate the
intervention in a non-critical driving situation.
In particular, the detection of obstacles can
be impaired if:
R
there is dirt on the sensors or anything else
®
covering the sensors
R
snow or heavy rain
R
interference by other radar sources
R
there are strong radar reflections, for
example in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different line
relative to the center of your vehicle
WARNING
G
PRE-SAFE®Brake does not react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
As a result, PRE-SAFE®Brake may neither
give warnings nor intervene in all critical
situations. There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
In order to maintain an appropriate distance
from the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.
X
To activate/deactivate: activate or
deactivate PRE-SAFE®Brake in the onboard computer (Y page 272).
When PRE-SAFE®Brake is activated, the
Ä symbol appears in the multifunction
display as long as the HOLD function is
Theft deterrent locking system

deactivated (Y page 207). On vehicles with
Active Parking Assist, the Ä symbol is
displayed when P is engaged or you are
driving faster than 22 mph (35 km/h).
Following damage to the frontend of the
vehicle, have the configurationand operation
of the radarsensors checked at a qualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the frontofthe vehicle.
STEER CONTROL
i
Observe the "Important safety notes"
section (Y page 66).
STEER CONTROL helps you by transmitting a
noticeable steering force to the steering
wheel in the direction required for vehicle
stabilization.
This steering assistance is provided in
particular if:
R
both right wheels or both left wheels are on
a wet or slippery road surface when you
brake
R
the vehicle starts to skid
If ESP®is malfunctioning, you will not receive
steering support from STEER CONTROL.
Power steering will, however, continue to
function.
