Rno accessories, such as cup holders, are
attached to the vehicle within the deploy-
ment area of an air bag, e.g. to doors or side
windows.
Rno heavy, sharp-edged or fragile objects
are in the pockets of your clothing. Store
such objects in a suitable place.
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.
GWARNING
Sensors to control the air bags are located in
the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to the
function of the sensors being impaired. The air
bags might therefore not function properly
anymore. Consequently, the air bags cannot
protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door pan-
eling carried out at a qualified specialist work-
shop.
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.
When deployed, the front air bags offer addi-
tional head and thorax protection for the
occupants in the driver's and front-passenger seats.
The PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps
inform you of the status of the front-
passenger front air bag (
Ypage 41).
The front-passenger front air bag will only
deploy if:
Rthe system, based on the OCS weight sen-
sor readings, detects that the front-
passenger seat is occupied (
Ypage 49).
The PASSENGER AIR BAG ON indicator
lamp is lit (
Ypage 49)
Rthe restraint system control unit predicts a
high accident severity
Knee bags
Driver's knee bag :deploys under the steer-
ing column and front-passenger knee bag ;
under the glove box. The driver's and front-
passenger knee bags are triggered together
with the front air bags.
The driver's and front-passenger knee bags
offer additional thigh, knee and lower leg pro-
tection.
Side impact air bags
GWARNING
Unsuitable seat covers could restrict or even
prevent the deployment of the air bags inte-

grated into the seats. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. In addition, the func-tion of the Occupant Classification System
(OCS) could be restricted. This poses an
increased risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Side impact air bags :deploy next to the
outer bolster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax protection. However, it does
not protect the:
Rhead
Rneck
Rarms
In the event of a side impact, the side impact
air bag is deployed on the side on which the
impact occurs.
The side impact air bag on the front-
passenger side deploys under the following
conditions:
Rthe OCS system detects that the front-
passenger seat is occupied or
Rthe belt tongue is engaged in the belt
buckle of the front-passenger seat
If the belt tongue is engaged in the belt
buckle, the side impact air bag on the front-
passenger side deploys if an appropriate acci-
dent situation occurs. In this case, deploy-
ment is independent of whether the front-
passenger seat is occupied or not.
Head bags
Head bags :deploy in the area of the side
windows at the front.
When deployed, the headbag enhances the
level of protection for the head. However, it
does not protect the:
Rchest
Rarms
In the event of a side impact, the headbag is
deployed on the side on which the impact
occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a headbag may be deployed in other
accident situations (
Ypage 54).
The headbag on the front-passenger side
does not deploy under the following condi-
tions:
ROCS has detected that the front-passenger
seat is unoccupied.
Rthe front-passenger seat belt is not fas-
tened.
If the belt tongue is engaged in the belt
buckle, the headbag on the front-passenger
side deploys if an appropriate accident situa-
tion occurs. In this case, deployment is inde-
pendent of whether the front-passenger seat
is occupied or not.

Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
Unlocking and opening doors from
the inside
!
The side windows will not open/close if
the battery is discharged or if the side win-
dows have iced up. It will then not be pos-
sible to close the door. Do not attempt to
force the door closed. You could otherwise
damage the door or the side window.
You can open a door from inside the vehicle
even if it has been locked.
If the vehicle was previously locked with the
SmartKey or with KEYLESS-GO, opening the
vehicle from the inside will activate the anti-
theft alarm system. Switch off the alarm
(

Side windows
Important safety notes
GWARNING
While opening the side windows, body parts
could become trapped between the side win-
dow and the door frame as the side window
moves. There is a risk of injury.
Make sure that nobody touches the side win-
dow during the opening procedure. If some-
body becomes trapped, release the switch or
pull the switch to close the side window again.
GWARNING
While closing the side windows, body parts in
the closing area could become trapped. There is a risk of injury.
When closing make sure that no parts of the
body are in the closing area. If somebody
becomes trapped, release the switch or press
the switch to open the side window again.
GWARNING
If children operate the side windows they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
Side window reversing feature
The front side windows are equipped with an
automatic reversing feature. If a solid object
blocks or restricts one of the front side win-
dows from traveling upwards during the auto-
matic closing process, the side window opens
again automatically. During the manual clos-
ing process, the side window only opens
again automatically after the corresponding
switch is released. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying
attention when closing a side window.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rwhile resetting
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the switch
to open the side window again.
