the restraint system are activated independ-
ently of each other in certain frontal collision
situations:
RFront air bags as well as driver's and front-
passenger knee bags
RWindow curtain air bag, if the system deter-
mines that deployment can offer additional
protection to that provided by the seat belt
The front-passenger front air bag is activated
or deactivated depending on the person on
the front-passenger seat. The front-
passenger front air bag can only deploy in an
accident if the PASSENGER AIR BAG ON indi-
cator lamp is lit. Observe the information on
the PASSENGER AIR BAG indicator lamps
(
Ypage 45).
Your vehicle has two-stage front air bags.
During the first deployment stage, the front
air bag is filled with propellant gas to reduce
the risk of injuries. The front air bag is fully
deployed with the maximum amount of pro-
pellant gas if a second deployment threshold
is reached within a few milliseconds.
The activation threshold of the Emergency
Tensioning Devices and the air bag are deter-
mined by evaluating the rate of vehicle decel-
eration or acceleration which occurs at vari-
ou s p
oints in the vehicle. This process is pre-
emptive in nature. Deployment should take
place in good time at the start of the collision.
The rate of vehicle deceleration or accelera-
tion and the direction of the force are essen-
tially determined by:
Rthe distribution of forces during the colli-
sion
Rthe collision angle
Rthe deformation characteristics of the vehi-
cle
Rthe characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a
decisive role in the deployment of an air bag.
Nor do they provide an indication of air bag
deployment. The vehicle can be deformed considerably,
without an air bag being deployed. This is the
case if only parts which are relatively easily
deformed are affected and the rate of decel-
eration is not high. Conversely, air bags may
be deployed even though the vehicle suffers
only minor deformation. This is the case if, for
example, very rigid vehicle parts such as lon-
gitudinal body members are hit, and sufficientdeceleration occurs as a result.
If th
e restraint system control unit detects a
side impact or if the vehicle rolls over, the
applicable components of the restraint sys-
tem are activated independently of each
other depending on the apparent type of acci-
dent.
RSide impact air bags on the side of impact, independently of the Emergency Tension-
ing Device and the use of the seat belt on
the driver's seat and in the rear compart-
ment seats
The side impact air bag on the front-
passenger side (front) deploys under the
following conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the belt tongue is engaged in the belt
buckle of the front-passenger seat
RWindow curtain air bag on the side of
impact, independently of the use of the
seat belt and independently of whether thefront-passenger seat is occupied
REmergency Tensioning Devices, if the sys-
tem determines that deployment can offer
additional protection in this situation
RWindow curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer addi-
tional protection to that provi ded b
y the
seat belt
iNot all air bags are deployed in an acci-
dent. The different air bag systems work
independently of each other.

Safety

If you or others come into contact with fuel,
observe the following:
RWash away fuel from skin immediately
using soap and water.
RIf fuel comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf fuel is swallowed, seek medical assis-
tance without delay. Do not induce vomit-
ing.
RImmediately change out of clothing which
has come into contact with fuel.
GWARNING
Electrostatic buildup can create sparks and
ignite fuel vapors. There is a risk of fire and
explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. Any existing electrostatic buildup is
thereby discharged.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again.
!Do not use diesel to refuel vehicles with a
gasoline engine. Do not switch on the igni-
tion if you accidentally refuel with the
wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the wrong fuel could result in damage to the
fuel system and the engine. Notify a quali-
fied specialist workshop and have the fuel
tank and fuel lines drained completely.
!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection
system could be blocked by particles from
the fuel can. If you overfill the fuel tank, fuel could spray
out when the fuel pump nozzle is removed.

General information
Pay attention to the important safety notes
(
Ypage 167).
If you unlock/lock the vehicle from the out-
side, the fuel filler flap also unlocks/locks.
The position of the fuel filler cap is displayed
8 in the instrument cluster. The arrow
next to the filling pump indicates the side of
the vehicle.

;NThe yellow Check Engine warning lamp lights up while the engine is running.
There may be a malfunction, for example:
Rin the engine management
Rin the fuel injection system
Rin the exhaust system
Rin the ignition system
Rin the fuel system
The emission limit values may be exceeded and the engine may be in emer-
gency mode.
XHave the vehicle checked as soon as possible at a qualified specialist work-
shop.
iIn some states, you must immediately visit a qualified specialist workshop
as soon as the yellow Check Engine warning lamp lights up. This is due to the
legal requirements in effect in these states. If in doubt, check whether such legal regulations apply in the state in which you are currently driving.
8N The yellow reserve fuel warning lamp lights up while the engine is running.
The fuel level has dropped into the reserve range.
XRefuel at the nearest gas station.
8N The yellow reserve fuel warning lamp flashes while the vehicle is in motion.
In addition, the ;Check Engine warning lamp may light up.
The fuel system pressure is too low. The fuel filler cap is not closed correctly
or the fuel system is leaking.
XCheck that the fuel filler cap is correctly closed.
XIf the fuel filler cap is not correctly closed: close the fuel filler cap.
XIf the fuel filler cap is closed:visit a qualified specialist workshop.
