worked components. In particular, systems
relevant to safety could also be affected. As aresult, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
curb or an unpaved road
R you drive too fast over an obstacle, e.g. a
curb or a hole in the road
R a heavy object strikes the undercarriage
or parts of the chassis
In situations like this, the body, the under-
carriage, chassis parts, wheels or tires
could be damaged without the damage
being visible. Components damaged in this
way can unexpectedly fail or, in the case of
an accident, no longer withstand the strain
they are designed to.
If the underbody paneling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody paneling. If
these materials come in contact with hot
parts of the exhaust system, they can catch fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If on con-
tinuing your journey you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
consult a qualified specialist workshop.

In the event of other types of impacts and
impacts below air bag deployment thresh-
olds, the air bags will not deploy. The driver
and passenger will then be protected to the
extent possible by a properly fastened seat
belt. A properly fastened seat belt is also nee-ded to provide the best possible protection in
a rollover.
Air bags provide additional protection; they
are not, however, a substitute for seat belts.
All vehicle occupants must fasten their seat
belts regardless of whether your vehicle is
equipped with air bags or not.
It is important for your safety and that of your passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective
function for the vehicle occupants in the
event of a crash.
iAfter an air bag has been deployed, have
the vehicle towed to the nearest qualified
specialist workshop, even if your vehicle is
ready to drive.
Front air bags
The front air bags increase protection for the driver's and front passenger's head and
chest.
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. They are deployed:
R at the start of an accident with a high rate of
vehicle acceleration or deceleration in a
longitudinal direction
R if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R independently of other air bags in the vehi-
cle
The release time of the front air bags is
dependent upon the use of the seat belt.
If the vehicle rolls over, the front air bags are
generally not deployed. If the system detects
high vehicle deceleration in a longitudinal
direction, the front air bags are deployed.
Your vehicle has adaptive, two-stage front air bags. In the event of a collision, the air bag
control unit evaluates the vehicle decelera-
tion. In the first deployment stage, the front
air bag is filled with enough propellant gas to
reduce the risk of injuries. The front air bag is fully deployed if a second deployment thresh-
old is exceeded within a few milliseconds.
The deployment of front-passenger front air
bag ; is also influenced by the weight cate-
gory of the front passenger, which is deter-
mined by the Occupant Classification System
(OCS) ( Y page 49).
The lighter the passenger-side occupant, the
higher the vehicle deceleration rate required
(predicted at the start of the impact) for sec- ond stage inflation of the front-passenger
front air bag. In the second stage, the front air
bags are inflated with the maximum amount
of propellant gas available.
The front air bags are not deployed in situa-
tions where a low impact severity is predic-
ted. You will then be protected by the fas-
tened seat belt.

Belt warning for the driver and front
passenger
Regardless of whether the driver's and front-passenger seat belts have already been fas-
tened, the 7 seat belt warning lamp lights
up for six seconds each time the engine is
started. It then goes out if the driver and the
front passenger have already fastened their
seat belts.
If the driver's seat belt is not fastened when
the engine is started, an additional warning
tone will sound. This warning tone stops after a maximum of six seconds or once the driv-
er's seat belt is fastened.
If after six seconds the driver or front
passenger have not fastened their seat belts
and the doors are closed, the 7 seat belt
warning lamp lights up:
R until the driver's or front passenger's seat
belt is fastened
R if a vehicle speed of 15 mph (25 km/h) is
exceeded, a warning tone also sounds with
increasing intensity for a maximum of
60 seconds or until the driver or front-
passenger seat belt has been fastened
If the driver/front passenger unfasten their
seat belt while the vehicle is in motion, the7 seat belt warning lamp lights up and a
warning tone sounds again.
The warning tone ceases even if the driver or
front-passenger seat belt has still not been
fastened after 60 seconds. The 7 seat belt
warning lamp stops flashing but remains illu-
minated.
After the vehicle comes to a standstill, the
warning tone is reactivated and the 7 seat
belt warning lamp flashes again if the vehicle
speed again exceeds 15 mph (25 km/h).
The 7 seat belt warning lamp only goes
out if:
R both the driver and the front passenger
have fastened their seat belts.
or R the vehicle is stationary and a door is open.
iFor more information on the 7 seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belts" ( Y page 260).
Emergency Tensioning Devices, seat
belt force limiters
GWARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer opera-
tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency Ten-
sioning Devices which have been triggered
immediately replaced at a qualified specialist
workshop.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of the front-passenger seat. This may oth-
erwise lead to the triggering of the Emer-
gency Tensioning Device in the event of an accident, which will then need to be
replaced.
iVehicles with PRE-SAFE ®
: an electric
motor is used by PRE-SAFE ®
to trigger the
tightening of the seat belt in hazardous sit- uations. This procedure is reversible.
The seat belts for the front seats and rear
outer seats are equipped with Emergency
Tensioning Devices and seat belt force limit-
ers.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat posi-
tions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
The ETDs can only be activated when: R the ignition is switched on
R the restraint systems are operational; see
"SRS warning lamp "( Y page 43)

GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro-tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended inthe vehicle.
If an infant or child is traveling in the vehicle:
X Secure the child with a child or infant seat
restraint system appropriate to the age and
weight of the child.
X Make sure that the infant or child is prop-
erly secured at all times while the vehicle is
in motion.
Special seat belt retractor
All seat belts except the driver's seat belt are equipped with a special seat belt retractor.
When activated, the special seat belt retrac-
tor ensures that the seat belt will not slacken
once the child restraint system has been
secured.
Installing a child restraint system: X Always comply with the manufacturer's
installation instructions.
X Pull the seat belt smoothly from the seat
belt retractor.
X Engage the seat belt tongue in the belt
buckle. Activating the special seat belt retractor:
X Pull the seat belt out fully and let the seat
belt retractor retract it again.
While the seat belt is retracting, you should
hear a ratcheting sound. The special seat
belt retractor is activated.
X Push down on the child restraint system to
take up any slack.
Removing a child restraint system/deactivat-
ing the special seat belt retractor:
X Always comply with the manufacturer's
installation instructions.
X Press the release button on the belt buckle,
hold the belt tongue firmly and guide it back
towards the belt sash guide.
The special seat belt retractor is deactiva-
ted.
GWARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt retrac- tor is disabled and the inertia real draws in a
portion of the seat belt. The seat belt cannot
be immediately refastened. There is an
increased risk of injury, possibly even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reactivate
the special seat belt retractor and secure the
child restraint system properly.
LATCH-type (ISOFIX) child seat anchors
in the rear
GWARNING
Children that are too large for a child restraint
must travel in seats using normal seat belts.
Position shoulder belt across the chest and
shoulder, not face or neck.
A booster seat may be necessary to achieve
proper seat belt positioning for children over
41 lb (18 kg) until they reach a height where a lap/shoulder belt fits properly without a boos-
ter.
