vehicle" (Y
page 55) in addition to the child
restraint system manufacturer's installation
and operating instructions.
Objects in the vehicle interior may prevent
an air bag from functioning correctly. Before
starting your journey and to avoid risks resulting
from the speed of the air bag as it deploys, make sure that:
R there are no people, animals or objects
between the vehicle occupants and an air bag
R there are no objects between the seat, door
and B-pillar
R no accessories, such as cup holders, are
attached to the vehicle within the deployment
area of an air bag, e.g. to doors or side win-
dows
R no heavy, sharp-edged or fragile objects are in
the pockets of your clothing. Store such
objects in a suitable place G
WARNING
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. G
WARNING
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 !
Do not place heavy objects on the front-
passenger seat. This could cause the system
to identify the seat as being occupied. In the
event of an accident, the restraint systems on the front-passenger side may be triggered
and have to be replaced.
Driver's air bag
0043deploys in front of the steer-
ing wheel. Front-passenger front air bag 0044
deploys in front of and above the glove box.
When deployed, the front air bags offer addi-
tional head and thorax protection for the occu-
pants in the driver's and front-passenger seats.
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the front-
passenger front air bag (Y page 41).
The front-passenger front air bag will only
deploy if:
R the system, based on the OCS weight sensor
readings, detects that the front-passenger
seat is occupied (Y page 48). The
PASSENGER AIR BAG OFF indicator lamp is
not lit (Y page 48)
R the restraint system control unit predicts a
high accident severity
Knee bags Driver's knee bag
0043deploys under the steering
column and front-passenger knee bag 0044under
the glove box. The driver's and front-passenger
knee bags are triggered together with the front
air bags. 46

R the mbrace service has been activated
properly.
R the necessary mobile phone network is
available. Protection against theft

Important safety notes
G
WARNING
If children are left unsupervised in the vehicle, they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shifting the automatic transmission out of
park position P
R Start 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. G
WARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to the
SmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
! Keep the SmartKey away from strong mag-
netic fields. Otherwise, the remote control
function could be affected.
Strong magnetic fields can occur in the vicin- ity of powerful electrical installations.
Do not keep the SmartKey: R with electronic devices, e.g. a mobile phone
or another SmartKey
R with metallic objects, e.g. coins or metal foil
R inside metallic objects, e.g. a metal case
This can affect the functionality of the Smart-
Key. Vehicles with KEYLESS-GO start function:
do
not keep the SmartKey in the trunk. Otherwise, the SmartKey may not be detected, e.g. when
starting the engine using the Start/Stop button.
A brief radio connection between the vehicle
and the SmartKey determines whether a valid
SmartKey is in, or in the direct vicinity of, the
vehicle.
This occurs, for example:
R when starting the engine
R while driving
R when using the trunk lid unlocking sensor
R when the external door handles are touched
R during convenience closing SmartKey functions
