Belt warning for the driver and front
passenger
Thevseat belt warning lamp in the instru-ment cluster is a reminder that all vehicle occu-pants must wear their seat belts. It may light upcontinuously or flash. In addition, there may bea warning tone.
Regardless of whether the driver's seat belt hasalready been fastened, thevseat belt warn-ing lamp lights up for six seconds each time theengine is started. If the front doors are closedand the driver's or front-passenger seat belt hasnot been fastened, thevseat belt warninglamp lights up again after the six seconds. Assoon as the driver's and front-passenger seatbelts are fastened or a front door is openedagain, thevseat belt warning lamp goes out.
If the driver's seat belt is not fastened after theengine is started, an additional warning tone willsound. The warning tone switches off after sixseconds or once the driver's seat belt is fas-tened.
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 warningtone sounds. A warning tone also sounds withincreasing intensity for 60 seconds or until thedriver or front passenger have fastened theirseat belts.
If the driver or front passenger unfasten theirseat belts during the journey, the seat belt warn-ing is activated again.
Air bags
Introduction
The installation point of an air bag can be rec-ognized by the AIRBAG marking.
An air bag complements the correctly fastenedseat belt. It is no substitute for the seat belt. The
air bag provides additional protection in appli-cable accident situations.
Not all air bags are deployed in an accident. Thedifferent air bag systems function independ-ently from one another (Ypage 55).
However, no system available today can com-pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injurycaused by an air bag due to the high speed atwhich the air bag must be deployed.
Important safety notes
GWARNING
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:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sitting correctly and maintain the great-
est possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
RAdjust the seats properly before beginningyour journey. Always make sure that the seatis in an almost upright position. The center ofthe head restraint must support the head atabout eye level.
RMove the driver's and front-passenger seatsas far back as possible. The driver's seat posi-tion must allow the vehicle to be driven safely.
ROnly hold the steering wheel on the outside.This allows the air bag to be fully deployed.
RAlways lean against the backrest while driv-ing. Do not lean forward or lean against thedoor or side window. You may otherwise be inthe deployment area of the air bags.
RAlways keep your feet in the footwell in frontof the seat. Do not put your feet on the dash-

of injury in the head and neck area, e.g. in the
event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
Using the fore-and-aft adjustment, adjust thehead restraint so that it is as close as possible toyour head.
GWARNING
If the driver's seat is not engaged, it could
move unexpectedly while the vehicle is in
motion. This could cause you to lose control of
the vehicle. There is a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the vehicle.
GWARNING
You could lose control of your vehicle if you do
the following while driving:
Radjust the driver's seat, head restraint,
steering wheel or mirrors
Rfasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt
before starting the engine.
GWARNING
If you adjust the seat height carelessly, you or
other vehicle occupants could be trapped and
thereby injured. Children in particular could
accidentally press the electrical seat adjust-
ment buttons and become trapped. There is a
risk of injury.
While moving the seats, make sure that your
hands or other body parts do not get under the
lever assembly of the seat adjustment sys-
tem.
GWARNING
The seat belt does not offer the intended level
of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
