If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
curb or an unpaved road
R you drive too fast over an obstacle, e.g. a
curb or a hole in the road
R a heavy object strikes the undercarriage
or parts of the chassis
In situations like this, the body, the under-
carriage, chassis parts, wheels or tires
could be damaged without the damage
being visible. Components damaged in this way can unexpectedly fail or, in the case of
an accident, no longer withstand the strain
they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come in contact with hot
parts of the exhaust system, they can catch fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If on con-
tinuing your journey you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
visit a qualified specialist workshop. Declarations of conformity
Vehicle components which receive
and/or transmit radio waves USA:
"The wireless devices of this vehicle
comply with Part 15 of the FCC Rules. Oper-
ation is subject to the following two condi-
tions: 1) These devices may not cause harm-
ful interference, and 2) These devices must
accept any interference received, including
interference that may cause undesired oper-
ation. Changes or modifications not expressly approved by the party responsible for com-
pliance could void the user’s authority to
operate the equipment."
Canada:
"The wireless devices of this vehicle
comply with Industry Canada license-exempt
RSS standard(s). Operation is subject to the
following two conditions: (1) These devices
may not cause interference, and (2) These
devices must accept any interference, includ- ing interference that may cause undesired
operation of the device." Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at a qualified specialist workshop. G
WARNING
If you connect equipment to the diagnostics
connection in the vehicle, it may affect the
operation of the vehicle systems. As a result, the operating safety of the vehicle could be
affected. There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle. G
WARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use loose floormats and do not place floormats on
top of one another.
! If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
Connecting equipment to the diagnostics
connection can lead to emissions monitoring information being reset, for example. This
may lead to the vehicle failing to meet the Introduction

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 prop-
erly 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 informa-
tion. Be sure to give the buyer this Operator's
Manual.
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 and does not indicate that there is a fire in the vehicle. The dust might cause
some temporary breathing difficulty for peo-
ple 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. You can
also open the window to allow fresh air to
enter the vehicle interior. The 0075SRS warn-
ing lamp lights up.
The air bag installation locations are identi-
fied by the AIR BAG symbol.
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 protec-
tion.
In the event of other types of impacts and
impacts below air bag deployment thresh-
olds, the air bags will not deploy. The driver
and passenger will then be protected to the
extent possible by a properly fastened seat
belt. A properly fastened seat belt is also nee- ded to provide the best possible protection in
a rollover.
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
passenger 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.
i After an air bag has been deployed, have
the vehicle towed to the nearest qualified
specialist workshop, even if your vehicle is
ready to drive.

Occupant safetySafety

The front seat belts and the outer seat belts in
the rear are equipped with Emergency Ten-
sioning Devices and seat belt force limiters.
The ETDs tighten the seat belts in an accident, pulling them close against the body.
The ETDs do not correct incorrect seat posi-
tions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
The ETDs can only be activated when:
R the ignition is switched on
R the restraint systems are operational; see
"0075 SRS warning lamp" (Y page 41)
R the belt tongue has engaged in the belt
buckle of the respective front seat
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 in the event of a head-on or rear-end colli-
sion if the vehicle decelerates or acceler-
ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact.
R in the event of a side impact if the vehicle
decelerates or accelerates rapidly in a lat-
eral direction on the side opposite to the
impact.
R in certain situations where the vehicle rolls
over if 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 and does not indicate that there is a fire in the vehicle. The dust might cause
some temporary breathing difficulty for peo-
ple 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. You can
also open the window to allow fresh air to
enter the vehicle interior. The 0075SRS warn-
ing lamp lights up. If the seat belt is also equipped with a seat
belt force limiter and this is triggered, the
force exerted by the seat belt on the vehicle
occupant is reduced.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which absorb part of the deceleration force.
This results in the force exerted on the occu- pant being distributed over a greater area. Children in the vehicle
Child restraint systems
Important safety notes G
WARNING
According to accident statistics, children are
safer when properly restrained in the rear
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, chil- dren 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 impor-
tant information when circumstances require you to place a child in the front passenger
seat:
R Your vehicle is equipped with air bag tech-
nology designed to deactivate the front 56
Children in the vehicleSafety

tem. Only secure a rearward-facing child
restraint system on a suitable rear seat.
R and you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible. When doing so,
ensure that the shoulder belt strap from the
belt outlet on the vehicle is routed towards the front to the shoulder belt guide on the
child restraint system. Set the belt height
adjustment so that the belt strap is routed
towards the front along the bottom.
The front-passenger air bag is not deactiva-
ted:
R on vehicles without an air bag deactivation
system on the front-passenger seat.
R on vehicles with an air bag deactivation
system on the front-passenger seat, unless
a child restraint system with transponders
for an air bag deactivation system is instal-
led on the front-passenger seat.
R on vehicles with an air bag deactivation
system on the front-passenger seat, if the
0073 PASSENGER AIR BAG OFF indicator
lamp is not lit.
To make you aware of this danger, a corre-
sponding warning sticker has been affixed to
the side of the dashboard and on both sides of the sun visor on the front-passenger side.
Information about recommended child
restraint systems is available at any author-
ized Mercedes-Benz Center. Warning notice on the front-passenger sun visor Warning symbol for a rearward-facing child
restraint system
NEVER use a rearward facing child restraint
system on a seat protected by an ACTIVE AIR
BAG in front of it, DEATH or SERIOUS INJURY
to the CHILD can occur.
LATCH-type (ISOFIX) child seat anchors
in the rear G
WARNING
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whose weight is greater than 48 lbs
(22 kg) who are secured using the safety belt integrated in the child restraint system. In the
event of an accident, a child might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is also secured
with the vehicle seat belt. Also secure the
child restraint system with the Top Tether
belt, if available.
When installing a child restraint system, be
sure to observe the manufacturer's installa-
tion instructions and the instructions for cor- rect use of the child restraint system.
! When installing the LATCH-type (ISOFIX)
child restraint system, make sure that the
seat belt for the center seat does not get
trapped. Otherwise, the seat belt could be
damaged. 60
