six seconds or when the driver's seat belt is
fastened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a
warning tone sounds. A warning tone also
sounds with increasing intensity for
60 seconds or until the driver or front
passenger have fastened their seat belts.
If the driver or front passenger unfasten their seat belts during the journey, the seat belt
warning is activated again.
i For more information on the
0076seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belts" (Y page 318). Air bags
Introduction The installation point of an air bag can be rec-
ognized by the AIR BAG symbol.
An air bag complements the correctly fas-
tened seat belt. It is no substitute for the seat
belt. The air bag provides additional protec-
tion in applicable accident situations.
Not all air bags are deployed in an accident.
The different air bag systems function inde-
pendently from one another (Y page 58).
However, no system available today can com- pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an air bag due to the high speed at which the air bag must be deployed.
Important safety notes G
WARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury. To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
R have fastened their seat belts correctly,
including pregnant women
R are sitting correctly and maintain the great-
est possible distance to the air bags
R follow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
R Adjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
center of the head restraint must support
the head at about eye level.
R Move the driver's and front-passenger
seats as far back as possible. The driver's
seat position must allow the vehicle to be
driven safely.
R Only hold the steering wheel on the out-
side. This allows the air bag to be fully
deployed.
R Always lean against the backrest while driv-
ing. Do not lean forwards or lean against
the door or side window. You may other-
wise be in the deployment area of the air
bags.
R Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth- erwise be in the deployment area of the air
bag.
R For this reason, always secure persons less
than 5 ft (1.50 m) tall in suitable restraint
systems. Up to this height, the seat belt
cannot be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
R Always secure children under 12 years of
age and less than 5 ft (1.50 m)in height in
suitable child restraint systems.
R Child restraint systems should be installed
on the rear seats. 50

ton once or twice on vehicles with KEY-
LESS-GO.
The system carries out a self-diagnosis.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six second s.
The PA SSENGER AIR BAG OFF indicator lamp
then displays the status of the front-
passenger front air bag. If the status of the
front-passenger front air bag changes while
the vehicle is in motion, an air bag display
message may appear in the instrument clus-
ter (Y page 295). When the front-passenger
seat is occupied, always pay attention to the
PASSENGER AIR BAG OFF indicator lamp. Be aware of the status of the front-passenger
front air bag both before and during the jour-ney.
If the PASSENGER AIR BAG OFF indicator
lamp:
R is lit, the front-passenger front air bag is
deactivated. They will then not be deployed in the event of an accident.
R does not light up: the front-passenger
front air bag is enabled. If, in the event of an
accident, all deployment criteria are met,
the front-passenger front air bag is
deployed. G
WARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is disabled. It will not be deployed in the event of
an accident and cannot perform its intended
protective function. A person in the front-
passenger seat could then, for example, come
into contact with the vehicle's interior, espe-
cially if the person is sitting too close to the
dashboard. This poses an increased risk of
injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
R the classification of the person in the front-
passenger seat is correct and the front-
passenger front air bag is enabled or disa- bled in accordance with the person in the
front-passenger seat
R the front-passenger seat has been moved
back as far back as possible.
R the person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct. G
WARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front air bag can
deploy in the event of an accident. The child
could be struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit. G
WARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, the child could, in the
event of an accident:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the air bag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even
fatal injury.
Move the front-passenger seat as far back as possible. Always make sure that the shoulder
belt strap is correctly routed from the vehicle
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and down-
wards from the vehicle belt sash guide. If nec- essary, adjust the vehicle belt sash guide and
the front-passenger seat accordingly. Always
observe the child restraint system manufac-
turer's installation instructions. 54
