Operating safety
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 while 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 as 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
qualified maintenance or repair facility for
further inspection or repairs.

For
you contact an authorized Mercedes-Benz
Center immediately to have the system
checked. Otherwise the SRS may not be
activated when needed in an accident, which
could result in serious or fatal injury. The SRS
might also deploy unexpectedly and
unnecessarily which could also result in injury
as well.
In addition, improper 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.
If it is necessary to modify an air bag system

Air bags
Warning!
G
Air bags are designed to reduce the potential
of injury and fatality in certain
R
frontal impacts (front air bags)
R
side impacts (side impact air bags and
window curtain air bags)
R
rollovers (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.
Occupant safety
Deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither harmful
to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some
temporary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of 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
To reduce the risk of injury when the front air
bags
inflate, it is very important for the driver
and front passenger to always be in a properly
seated position and to wear their respective
seat belt.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the seat backrest.
Fasten your seat belt and make sure it is
properly positioned on your body.
Since 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 properly fastened in a
position that is as upright as possible with
your back against the seat 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) or more.
You should be able to accomplish this by
adjusting the seat and steering wheel. If

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.
R
Canada only: Children 12 years old and
under must never ride in the front seat,
except in a Mercedes-Benz authorized
BabySmart™ compatible child seat, which
operates with the BabySmart™ air bag
deactivation system installed in the vehicle
to deactivate the front passenger front air
bag when it is installed properly. Otherwise
they will be struck by the air bag when it
inflates in a crash. If this happens, serious
or fatal injury will result.
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.
There is a possibility for a side impact air bagrelated injury if occupants, especially
children,

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:
are not properly seated or restrained
(1) Always sit as upright as possible,
wear the seat belt properly, and for
children 12 years old and under,
use an appropriately sized infant
restraint, toddler restraint, or
booster seat recommended for the
size and weight of the child.
(2) Always wear seat belts properly.
Air bags are designed to deploy only in certain
R
frontal impacts (front air bags)
R
side impacts (side impact and window
curtain air bags) which exceed preset
deployment thresholds
R
rollovers (window curtain air bags)
Only
in the event of such a situation will they
provide their supplemental protection.
The driver and passengers should always
wear their seat belts. Otherwise it is not
possible for the air bags to provide their
supplemental protection.
In case of other types of impacts and impacts
below air bag deployment thresholds, air
bags will not deploy. The driver and
passengers will then be protected to the
extent possible by a properly fastened seat
belt. A properly fastened seat belt is also
needed to provide the best possible
protection in a rollover.
Air bags are not a substitute for seat belts.
Always wear your seat belt, regardless of
whether or not your vehicle is equipped with
air bags.
It is important to your safety and that of your
passengers to have deployed air bags
replaced and to have any malfunctioning air

Occupant Classification System
Safety and security
Occupant Classification System (OCS) is
The
standard equipment in USA.

occupant weight category determined by
weight sensor readings from the front
passenger seat.
The system does not deactivate
R

To be classified correctly, the front passenger
must sit
R
with the seat belt properly fastened
R
in a position that is as upright as possible
with the back against the seat backrest
R
with the feet on the floor
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by leaning
on armrests), the OCS may not be able to
properly approximate the occupant’s weight
category.
Furthermore, the occupant weight may
appear to increase or decrease due to the
following: objects hanging on the seat, lodged
underneath the seat, stuffed between the
seat and middle console or the seat and door,
other passengers pushing on the seat, or
objects applying pressure to the back of the
seat. Always make sure the seat has
clearance in all directions at all times.
If your seat, including the trim cover and
cushion, needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Both the driver and the front passenger
should always use the 42
indicator lamp as an indication of whether or
not the front passenger is properly
positioned.
Warning!
G
If the 42 indicator lamp
illuminates when an adult or someone larger
than a small individual is in the front
passenger seat, have the front passenger
reposition himself or herself in the seat until
the 42 indicator lamp goes out,
or
check whether objects are caught under or
around the seat.
In the event of a collision, the air bag control
unit will not allow front passenger front air bag
deployment when the OCS has classified the
front passenger seat occupant as weighting
as much as or less than a typical 12-monthold child in a standard child restraint or if the
front passenger seat is 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 42 indicator lamp
will illuminate when the engine is started and
remain illuminated, indicating that the front
passenger front air bag is deactivated.

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
Safety and security
require you to place a child in the front
passenger seat:
R
Children 12 years old and under must never
ride in the front seat, except in a MercedesBenz authorized BabySmart™ compatible
child seat, which operates with the
BabySmart™ system installed in the vehicle
to deactivate the front passenger front air
bag when it is installed properly. Otherwise
they will be struck by the air bag when it
inflates in a crash. If this happens, serious
or fatal injury will result.
R
A child 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 BabySmart™
compatible rear-facing child restraint on
the front passenger seat because
circumstances require you to do so, make
sure the 42 indicator lamp is
illuminated, indicating that the front
passenger front air bag is deactivated.
Should the 42 indicator lamp
not illuminate or go out while the restraint
is installed, please check installation.
Periodically check the 42
indicator lamp while driving to make sure
the 42 indicator lamp is
illuminated.
If the 42 indicator
lamp goes out or remains out, do not
transport a child on the front passenger
seat until the system has been repaired.
A child 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
When using a BabySmart™ compatible child
seat on the front passenger seat, the front
passenger
front air bag will not deploy only if
the 42 indicator lamp remains
illuminated.
Please be sure to check the 42
indicator lamp every time you use a
BabySmart™ compatible child seat on the
front passenger seat. Should the
42 indicator lamp go out while
the restraint is installed, please check
installation. If the 42 indicator
lamp remains out, do not use the
BabySmart™ restraint to transport a child on
the front passenger seat until the system has
been repaired.

Occupant safety
Warning!
G
Do not place powered-on laptops, mobile
phones, electronic tags such as those used in
ski passes and like electronic devices on the
front passenger seat. Signals from such
devices may interfere with the BabySmart™
air bag deactivation system. Such signal
interference may cause the 42
indicator lamp not to come on during self-test.
The SRS indicator lamp + and/or the
42 indicator lamp could be
continuously lit, indicating that the system is
not functioning. The front passenger front air
bag could deploy inadvertently or fail to
deploy in an accident.
Warning!
G
The BabySmart™ air bag deactivation system
will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart™
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness off the BabySmart™ air bag
deactivation system. The bottom of the child
seat must make full contact with the front
passenger seat cushion. An incorrectly
mounted child seat could cause injuries to the
child in case of an accident, instead of
protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
Seat belts
Safety notes
The use of seat belts and infant and child
restraint systems is required by law in all 50
states, the District of Columbia, the U.S.
territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened whenever the vehicle is in motion.

curtain air bags and ETDs).
R
Never wear the shoulder belt under your
arm,
against your neck or off your shoulder.
In a frontal crash, your body 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 distribute impact forces.
The twisted seat belt against your body
could cause injuries.

The use of infant or child restraints is required
by law in all 50 states, the District of
Columbia, the U.S. territories and all
Canadian provinces.
Infants and small children should be seated
in an appropriate infant or child restraint
system. They must be properly secured in
accordance with the manufacturer’s
instructions for the child restraint. All infant
or child restraint systems must comply with
U.S. Federal Motor Vehicle Safety Standards
213 and 225 and Canadian Motor Vehicle
Safety Standards 213 and 210.2.
A statement by the child restraint
manufacturer of compliance with these
standards can be found on the instruction
label on the restraint and in the instruction
manual provided with the restraint.
When using any infant restraint, toddler
restraint, or booster seat, make sure to
carefully read and follow all manufacturer’s
instructions for installation and use.
Please read and observe warning labels
affixed to the inside of the vehicle and to
infant or child restraints.

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.

Canada only: Children 12 years old and
under must never ride in the front seat,
except in a Mercedes-Benz authorized
BabySmart™ compatible child seat, which

front passenger front air bag when it is
installed properly. Otherwise they will be
struck by the air bag when it inflates in a
crash.
If this happens, serious or fatal injury
will result.
R
A child 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 42
indicator lamp is illuminated, indicating
that the front passenger front air bag is
deactivated. Should the 42
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
42 indicator lamp while
driving to make sure the 42
indicator lamp is illuminated. If the
42 indicator lamp goes out or
remains out, do not transport a child on the
front passenger seat until the system has
been repaired.

This section contains information about the
following driving safety systems:
R
ABS (Antilock Brake System)
R
BAS (Brake Assist System)
R
EBP (Electronic Brake Proportioning)
R
ESP® (Electronic Stability Program)
i
In winter operation, the maximum
effectiveness of most of the driving
systems described in this section is only
Driving safety systems
achieved with winter tires, or snow chains
as required.
Safety notes
Warning!
G
The following factors increase the risk of
accidents:
R
Excessive speed, especially in turns
R
Wet and slippery road surfaces
R
Following another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the
natural laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear.
ABS
Observe Safety notes, see page 63.
G
Warning!

Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS

and significantly reduces braking
effectiveness.
The Antilock Brake System (ABS) regulates
the
brake pressure so that the wheels do not
lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of
approximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even to light brake pressure.
The ABS indicator lamp ! indicator lamp
in the instrument cluster comes on when you
Safety and security
switch on the ignition. It goes out when the
engine is running.
Braking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal. The pulsation indicates that the
ABS is in the regulating mode.
X
Keep firm and steady pressure on the brake
pedal while you feel the pulsation.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
braking power and the ability to steer
namely
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.

such as the BAS or the ESP® are also
If the ABS malfunctions, the wheels may lock
during hard braking, reducing steering
capability
and extending the braking distance.
BAS
Observe Safety notes, see page 63.
G
The Brake Assist System (BAS) operates in
emergency
situations. If you apply the brakes
very quickly, the BAS provides full brake
boost automatically, thereby potentially
reducing the braking distance.
X
Apply continuous full braking pressure until
the emergency braking situation is over.
The ABS will prevent the wheels from
locking.
When you release the brake pedal, the brakes
function again as normal. The BAS is then
deactivated.
Warning!
G
If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore,
the braking distance may increase.
EBP
Observe Safety notes, see page 63.
G
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allowing
rear brakes to supply a greater proportion
the
of the braking effort in straight-line braking
without a loss of vehicle stability.
Warning!
G
If the EBP malfunctions, the brake system will
still function with full brake boost. However,
the rear wheels could lock up during
emergency braking situations, for example.
You could lose control of the vehicle and
cause an accident.
Adapt your driving style to the changed
driving characteristics.

ESP
Observe Safety notes, see page 63.
G
The Electronic Stability Program (ESP®) is
operational
as soon as the engine is running.
It monitors the vehicle’s traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP® recognizes that the vehicle deviates
from the direction of travel as intended by the
driver. By applying brakes to individual
wheels and by limiting the engine output, the
ESP® works to stabilize the vehicle. The
ESP® is especially useful while driving off and
on wet or slippery road surfaces. The ESP
®
also stabilizes the vehicle during braking and
steering maneuvers.
The ESP® warning lamp d in the
instrument cluster comes on when you switch
on the ignition. It goes out when the engine
is running.
The ESP® warning lamp d in the
instrument cluster flashes when the ESP® is
engaged.
Warning!
G
Never switch off the ESP® when you see the
ESP® warning lamp d flashing in the
instrument cluster. In this case proceed as
follows:
R
When driving off, apply as little throttle as
possible.
R
While driving, ease up on the accelerator
pedal.
R
Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESP® cannot
prevent accidents resulting from excessive
speed.
!
Only
conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized

brake is being tested on a brake test
dynamometer. Such testing should be no
longer than 10 seconds.
Active braking action through the ESP
may otherwise seriously damage the brake
system which is not covered by the
Mercedes-Benz Limited Warranty.

The ESP® will only function properly if you
use wheels of the recommended tire size
as specified in the “Technical data” section
of this Operator’s Manual.
i
The Distronic system and cruise control
switch off automatically when the ESP
engages.
Electronic Traction System (4-ETS)
Observe Safety notes, see page 63.
G
The 4-ETS (four-wheel Electronic Traction
System) is a component of the ESP®. The
4-ETS
improves the vehicle’s ability to utilize
available traction, especially under slippery
road conditions by applying the brakes to a
spinning wheel. In addition, more power is
transferred to the wheel(s) with traction.
When you switch off the ESP®, the 4-ETS is
still enabled.
