Front seat adjustment

Wa rn in g!

Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause the
driver to lose control of the vehicle.

Never ride in a moving vehicle with the seat back
reclined. Sitting in an excessively reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or fatal injuries. The seat back
and seat belts provide the best restraint when the
wearer is in an upright position and belts are
properly positioned on the body.

Never place hands under seat or near any moving
parts while a seat is being adjusted.

When leaving the vehicle always remove the
electronic key from the starter switch, and lock
your vehicle.

The power seats can also be operated with the
driver’s or front passenger door open. Do not leave
children unattended in the vehicle, or with access
to an unlocked vehicle. Unsupervised use of vehicle
equipment may cause serious personal injury.

To operate the front power seat adjustment switches,
turn the electronic key in starter switch to position 1
or 2 (with respective door open, the power seats can
also be operated with the electronic key removed or in
starter switch position 0).

Power seat (optional)

The switches are located in each door.

We recommend to adjust the power seat in the following
order:

1 Seat, up/down

Press the switch (up/down direction) until
comfortable seating position with still sufficient
headroom is reached.

2 Seat adjustment, fore/ aft

Press the switch (fore/aft direction) until a
comfortable seating position is reached that still
allows you to reach the accelerator/brake pedal
safely. The position should be as far rearward as
possible, consistent with ability to properly operate
controls.

Press the switch in the direction of the arrow until
your legs are lightly supported.

4 Backrest tilt

Press the switch in the direction of the arrow until
your arms are slightly angled when holding the

also airbag section on page 72 for proper seat
positioning.

In addition, also adjust the steering wheel to ensure
adequate control, reach, operation, and comfort.

Both the inside and outside rear view mirrors should be
adjusted for adequate rearward vision.

Fasten seat belts. Infants and small children should be
seated in a properly secured restraint system that
complies with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.

All seat, head restraint, steering wheel, and rear view
mirror adjustments as well as fastening of seat belts
should be done before the vehicle is put into motion.

Warn ing!

Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
which operates with the BabySmart

TM

compatible child seat,

TM

system
installed in the vehicle to deactivate the passenger
side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury can result.

According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.

A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.

Seat belts and integrated restraint system

Your vehicle is equipped with seat belts for all seats,
emergency tensioning retractors for all seat belts, dual
front airbags, door mounted side impact airbags, and
head protective window curtain airbags. Their
protective functions are designed to complement one
another.

Seat belts

Important!

Laws in most states and all Canadian provinces require
seat belt use.

All states and provinces require use of child restraints
that comply with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.

All child restraints systems are designed to be secured
in vehicle seats by lap belts or the lap belt portion of a
lap-shoulder belt.

For your safety and that of your passengers we strongly
recommend their use.

Warn ing!

Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
which operates with the BabySmart

TM

compatible child seat,

TM

system
installed in the vehicle to deactivate the passenger
side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury will result.

According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.

A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.

Wa rn in g!

Never ride in a moving vehicle with the backrest
reclined. Sitting in an excessively reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or even fatal injuries. The
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.

Seat belt nonusage warning system

With the electronic key in starter switch position 2, a
warning sounds for a short time if the driver’s seat belt
is not fastened.

Automatic comfort-fit seat belt:

An automatic comfort-fit feature for driver and front
passenger seat belt is activated when the electronic key
in the starter switch is turned to position 1 or 2.

The retraction force of the inertia reel is reduced,
increasing the level of seat belt comfort.

Note:

For cleaning and care of the seat belts see page 365.

Failure to wear and properly fasten and position
your seat belt greatly increases your risk of
injuries and their likely severity in an accident.
You and your passengers should always wear seat
belts.

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 wearing your seat belt.

Warn ing!

Never let more people ride in the vehicle than there
are seat belts available. Be sure everyone riding in
the vehicle is correctly restrained with a separate
seat belt.

Fastening seat belts

1 Latch plate

2 Buckle

3 Release button

Push latch plate (1) into buckle (2) until it clicks. Do not
twist the belt. A twisted seat belt may cause injury.

The lap belt should be positioned as low as possible on
your hips and not across the abdomen.

Warn ing!

Always fasten your seat belt before driving off.
Always make sure your passengers are properly
restrained – even those sitting in the rear.

Tighten the lap portion to a snug fit by pulling shoulder
portion up.

The shoulder portion of the seat belt must be pulled
snug and checked for snugness immediately after
engaging it.

Adjust seat belt so that shoulder portion is located as
close as possible to the middle of your shoulder (it
should not touch the neck). For this purpose, you can
adjust the height of the belt outlet.

Caution!

For safety reasons, avoid adjusting the seat or seat back
into positions which could affect the correct seat belt
positioning.

To raise, slide belt outlet upward.

To lower, press button (4) and slide belt outlet
downward.

Unfastening of seat belts

Press release button (3) in the belt buckle (2).

Allow the retractor to completely rewind the seat belt by

USE SEAT BELTS PROPERLY.

• 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 case of an accident.

• 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 airbag, front passenger airbag, side
impact airbags, head protection window
curtain airbags for side windows), “ETR” (seat
belt emergency tensioning retractors), and
front seat knee bolsters. The system is
designed to enhance the protection offered to
properly belted occupants in certain frontal
(front airbags) and side (side impact and
window curtain airbags) impacts which exceed
preset deployment thresholds.

• Never wear the shoulder belt under your arm,
against your neck or off your shoulder. In a
crash, your body would move too far forward.
That would increase the chance of head and
neck injuries. The belt would also apply too
much force to the ribs or abdomen, which
could severely injure internal organs such as
your liver or spleen.

• Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys etc., as these might
cause injuries.

• Position the lap belt as low as possible on your
hips and not across the abdomen. If the belt is
positioned across your abdomen, it could cause
serious injuries in a crash.

• Each seat belt should never be used for more
than one person at a time. Do not fasten a seat
belt around a person and another person or
other objects.

• Belts should not be worn twisted. In a crash,
you wouldn’t have the full width of the belt to
manage impact forces. The twisted belt against
your body could cause injuries.

• Pregnant women should also use a lap­shoulder belt. The lap belt portion should be
positioned as low as possible on the hips to
avoid any possible pressure on the abdomen.

• Never place your feet on the instrument panel
or on the seat. Always keep both feet on the
floor in front of the seat.

USE CHILD RESTRAINTS PROPERLY.

Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
which operates with the BabySmart

TM

compatible child seat,

TM

system
installed in the vehicle to deactivate the passenger
front airbag when it is properly installed.

Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury will result.

According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in the back
seats and be seated in an appropriate infant or
child restraint system, which is properly secured
with the vehicle’s seat belt, fully in accordance
with the child seat manufacturer’s instructions.

A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.

Children too big for child restraint systems must
ride in back seats using regular seat belts. Position
shoulder belt across chest and shoulder, not face or
neck. A booster seat may be necessary to achieve
proper belt positioning.

any child on the front passenger seat. See page 289 for

notes on the ü indicator lamp.

Warn ing!

TM

The BabySmart

airbag 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 of the deactivation system. The
bottom of the child seat must make full contact
with the 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.

The passenger front airbag will not deploy only if

the ü indicator lamp remains illuminated.

Please be sure to check the indicator every time
you use the special system child seat. Should the
light go out while the restraint is installed, please
check installation. If the light remains out, do not
use the BabySmart

Supplemental Restraint System (SRS)

Airbags are intended as a supplement to seat belts.
Airbags alone cannot protect as well as airbags plus
seat belts in impacts for which the airbags were
designed to operate, and do not afford any protection
whatsoever in crashes for which the airbags are not
designed to deploy.

The SRS uses two crash severity levels (thresholds) to
activate either the emergency tensioning retractor (ETR)
or front airbag or both. Activation depends on the
direction and severity of the impact exceeding the
preset thresholds and whether the seat belt is fastened.

Seat belt fastened

• first threshold exceeded: ETR activates

• second threshold exceeded: airbag also activates

Seat belt not fastened

Front seats:

• first threshold exceeded: airbag activates, not ETR

Rear seats:

• first threshold exceeded: ETR activates

Driver and front passenger and rear seat systems
operate independently of each other.

Emergency tensioning retractor (ETR)

The seat belts for the front and rear seats are equipped
with emergency tensioning retractors. These tensioning
retractors are located in each belt’s inertia reel and
become operationally ready with the electronic key in
starter switch position 1 or 2.

The emergency tensioning retractors are designed to
activate only when the seat belts are fastened during
frontal impacts exceeding the first threshold of the SRS

They remove slack from the belts in such a way that the
seat belts fit more snugly against the body restricting its
forward movement as much as possible.

In cases of other frontal impacts, angled impacts, roll­overs, certain side impacts, or other accidents without
sufficient frontal or rear impact forces, the emergency
tensioning retractors will not be activated. The driver
and passengers will then be protected by the fastened
seat belts and inertia reel in the usual manner.

Note:

The front passenger ETR activates only if the front
passenger seat is occupied.

Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy and the ETR to activate in a crash exceeding the
appropriate threshold.

Airbags

Front airbags

1 Driver airbag

2 Front passenger airbag

The most effective occupant restraint system yet
developed for use in production vehicles is the seat belt.
In some cases, however, the protective effect of a seat
belt can be further enhanced by an airbag.

In conjunction with wearing the seat belts, the driver
and front passenger airbags can provide increased
protection for the driver and front passenger in certain
frontal impacts exceeding preset thresholds.

Side impact and head protection window curtain airbags
can provide increased protection to belted occupants on
the impacted side of the vehicle in side impacts
exceeding its preset threshold.

The operational readiness of the airbag system is
verified by the indicator lamp “SRS” in the instrument
cluster when turning the electronic key in starter switch
to position 1. When turning the electronic key in starter
switch to position 2 the indicator lamp “SRS” in the
instrument cluster comes on. If no fault is detected, the
lamp will go out when the engine is running. After the
lamp goes out, the system continues to monitor the
components and circuitry of the airbag system and will
indicate a malfunction by coming on again. If the lamp
does not come on at all or if it fails to extinguish or if it
comes on thereafter, a malfunction in the system has
been detected.

The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.

Have the system checked at your authorized
Mercedes-Benz Center immediately.

In the operational mode, after the indicator lamp has
gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and front passenger seat belt buckle harnesses,
and low voltage in the entire system are detected and
indicated.

Warn ing!

In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit 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, or it might deploy
unexpectedly and unnecessarily which could also
result in injury.

Note:

See page 285 for information on the supplemental
restraint system (SRS) indicator lamp.

illuminated.

Note:

Heavy objects on the front passenger seat can appear to

Side impact airbags, window curtain airbags

Side impact airbags

The side impact airbags are designed to activate only in
certain side impacts exceeding a preset threshold. Only
the side impact airbags on the impacted side of the
vehicle deploy.

The side impact airbag for the front passenger deploys
only if the front passenger seat is occupied.

The side impact airbag for the right rear passenger
deploys only if a preset threshold is exceeded. The side
impact airbag for the left rear passenger deploys
together with the side impact airbag for the driver.

Side impact airbags operate best in conjunction with a
properly positioned and fastened seat belt.

Window curtain airbag

The head protection window curtain airbags afford
greater protection against injuries to the head and
upper body. They fill up in the area between the A and
C pillars (see arrows) between the side windows and an
occupant’s head.

The window curtain airbags are designed to activate
only in certain side impacts exceeding a preset
threshold. Only the head protection window curtain
airbag on the impacted side of the vehicle deploys.

Important!

Airbags are designed to activate only in certain
frontal (front airbags) impacts, or side (side impact
and head protection window curtain airbags)
impacts which exceed preset thresholds.

Only during these types of impacts, if of sufficient
severity to meet the deployment thresholds, will
they provide their supplemental protection.

The driver and passenger should always wear their
seat belts, otherwise it is not possible for the airbags
to provide their supplemental protection.

In cases of other frontal impacts, angled impacts,
roll-overs, other side impacts, rear collisions, or
other accidents, the airbags will not be activated.
The driver and passengers will then be protected by
the fastened seat belts.

We caution you not to rely on the presence of the
airbags in order to avoid wearing your seat belt.

Wa rn in g!

Airbags are designed to reduce the potential of
injury in certain frontal (front airbags) impacts, or
side (side impact and head protection window
curtain airbags) impacts which may cause
significant injuries, however, no system available
today can totally eliminate injuries and fatalities.

The activation of the “SRS” temporarily releases a
small amount of dust from the airbags. This dust,
however, is neither injurious 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
airbag inflates, then get fresh air by opening a
window or door.

Your vehicle was originally equipped with airbags
which are designed to activate in certain impacts
exceeding a preset threshold to reduce the potential
and severity of injury. It is important to your safety
and that of your passenger that you replace deployed
airbags and repair any malfunctioning airbags to
ensure the vehicle will continue to provide crash
protection for occupants.

Warn ing!

To reduce the risk of injury when the front airbags
inflate, it is very important for the driver and front
passenger to always be in a properly seated
position and to wear your seat belt.

For maximum protection in the event of a collision
always be in normal seated position with your back
against the backrest. Fasten your seat belt and
ensure that it is properly positioned on your body.

Since the airbag inflates with considerable speed
and force, a proper seating and hands on steering
wheel position will help to keep you at a safe
distance from the airbag. Occupants who are
unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it inflates
with great force in the blink of an eye:

• Sit properly belted in an upright position with
your back against the backrest.

• Adjust the driver seat as far as possible
rearward, still permitting proper operation of
vehicle controls. The distance from the center
of the driver’s breastbone to the center of the
airbag cover on the steering wheel must be at
least ten inches (25 cm) or more. You should be
able to accomplish this by a combination of
adjustments to the seat and steering wheel. If
you have any problems, please see your
authorized Mercedes-Benz Center.

• Do not lean with your head or chest close to the
steering wheel or dashboard.

• Keep hands on the outside of steering wheel
rim. Placing hands and arms inside the rim
can increase the risk and potential severity of
hand /arm injury when driver front airbag
inflates.

• Adjust the front passenger seat as far as
possible rearward from the dashboard when
the seat is occupied.

• Occupants, especially children, should never
lean their heads in the area of the door where
the side airbag inflates. This could result in
serious injuries or death should the airbag be
triggered.

• Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized Baby Smart
compatible child seat, which operates with the
BabySmart

TM

system installed in the vehicle to

TM

deactivate the passenger side front airbag
when it is properly installed. Otherwise they
will be struck by the airbag when it inflates in
a crash. If this happens, serious or fatal injury
can result.

Failure to follow these instructions can result in
severe injuries to you or other occupants.

Wa rn in g!

Accident research shows that the safest place for
children in an automobile is in the rear seat.
Should you choose to place a child 12 years old or
under in the front passenger seat of your vehicle,
you must properly use a BabySmart
restraint which will turn off the passenger side
front airbag. BabySmart

TM

will not, however, turn

TM

child

off the vehicle’s side impact airbag.

It should be noted that with respect to both front
and rear side impact airbags there is a possibility
for a side airbag related injury if occupants,
especially children, are not properly seated or
restrained when next to a side airbag which needs
to deploy rapidly in a side impact in order to do its
job.

Warn ing!

To help avoid the possibility of injury, please follow
these guidelines: (1) occupants, especially
children, should never place their bodies or lean
their heads in the area of the door or rear quarter
trim panels where the side airbag inflates. This
could result in serious injuries or death should the
side airbag be activated; (2) always sit upright,
properly use the seat belts and use an
appropriately sized infant or child restraint system
for all children 12 years old or under; and (3)
always wear seat belts properly.

Safety guidelines for the seat belt, emergency
tensioning retractor and airbag

Warn ing!

• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Center.

• Airbags and “ETR’s” are designed to function
on a one-time-only basis. An airbag or
emergency tensioning retractor (ETR) that was
activated must be replaced.

• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, door trim panels, or door frame trims,
and installation of additional electrical/
electronic equipment on or near “SRS”
components and wiring. Keep area between
airbags and occupants free from objects (e.g.
packages, purses, umbrellas, etc).

• Do not pass belts over sharp edges.

• Do not make any modification that could
change the effectiveness of the belts.

• Do not hang items such as coat hangers from
the coat hooks or handles over the door. These
items may turn into projectiles and cause head
and other injuries when curtain airbag is
deployed.

• An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.

• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the “SRS”.

• In addition, through improper work there is a
risk of rendering the “SRS” inoperative or
causing unintended airbag deployment. Work
on the “SRS” must therefore only be performed
by an authorized Mercedes-Benz Center.

• For your protection and the protection of
others, when scrapping the airbag unit or
emergency tensioning retractor, our safety
instructions must be followed. These
instructions are available from your
authorized Mercedes-Benz Center.

• Given the considerable deployment speed and
the textile structure of the airbags, there is the
possibility of abrasions or other injuries
resulting from airbag deployment.

When you sell your vehicle we strongly urge you to give
notice to the subsequent owner that it is equipped with
an “SRS” by alerting them to the applicable section in
the Operator’s Manual.

Infant and child restraint systems

We recommend all infants and children be properly
restrained at all times while the vehicle is in motion. All
lap-shoulder belts except the driver seat belt have
special seat belt retractors for secure fastening of child
restraints.

To activate, pull shoulder belt out completely and let it
retract. During the seat belt retraction a ratcheting
sound can be heard to indicate that the special seat belt
retractor is activated. The belt is now locked.

To deactivate, release seat belt buckle and let seat belt
retract completely. The seat belt can again be used in
the usual manner.

Note:

For child seats with mounting fittings for tether
anchorages refer to page 84 (installation of infant and
child restraint systems).

Wa rn in g!

Never release the seat belt buckle while vehicle is
in motion, since the special seat belt retractor will
be deactivated.

Important!

The use of infant or child restraints is required by law in
all 50 states and all Canadian provinces.

Infants and small children should be seated in an
appropriate infant or child restraint system properly
secured by a lap-shoulder belt, and that complies with
U.S. Federal Motor Vehicle Safety Standard 213 and
Canadian Motor Vehicle Safety Standard 213.
A statement by the child restraint manufacturer of
compliance with this standard can be found on the
instruction label on the restraint and in the instruction
manual provided with the restraint.

When using any infant or child restraint system, be 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.

Wa rn in g!

Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmart
which operates with the BabySmart

TM

compatible child seat,

TM

system
installed in the vehicle to deactivate the passenger
front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury can result.

According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.

Infants and small children should never share a
seat belt with another occupant. During an
accident, they could be crushed between the
occupant and seat belt.

Children too big for child restraint systems must
ride in back seats using regular seat belts. Position
shoulder belt across chest and shoulder, not face or
neck. A booster seat may be necessary to achieve
proper belt positioning for children from 41 lbs. to
the point where a lap/ shoulder belt fits properly
without one.

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.

Do not leave children unattended in the vehicle;
even if the children are secured in a child restraint
system. Unsupervised children in a child restraint
system may use vehicle equipment and may cause
serious personal injury.
