In situations like this, the body, the
undercarriage, chassis parts, wheels or
tires could be damaged withou tthe
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 for an
extended period, they can catch fire.
Have the vehicle checked and repaired
immediately at a qualified specialist
workshop. If on continuing 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, visit a qualified
specialist workshop. Declarations of conformity
Vehicle components which receive
and/or transmit radio waves USA:
"The wireless devices of this vehicle
comply with Part 15 of the FCC Rules.
Operation is subject to the following two
conditions: 1) These devices may not cause
harmful interference, and 2) These devices
must accept any interference received,
including interference that may cause
undesired operation. Changes or
modifications not expressly approved by the
party responsible for compliance could void
the user’s authority to operate the
equipment."
Canada: "The wireless devices of this vehicle
comply with Industry Canada license-exempt
RSS standard(s). Operation is subject to the
following two conditions: (1) These devices
may not cause interference, and (2) These
devices must accept any interference, including interference that may cause
undesired operation of the device." Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop. G
WARNING
If you connect equipment to the diagnostics
connection in the vehicle, it may affect the
operation of the vehicle systems. As a result,
the operating safety of the vehicle could be
affected. There is a risk of an accident.
Do not connect any equipment to a
diagnostics connection in the vehicle. G
WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct adepressed pedal.
The operating and road safety of the vehicle
is jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficien tclearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
! If the engine is switched off and
equipmen tonthe diagnostics connection
is used, the starter battery may discharge.
Connecting equipment to the diagnostics
connection can lead to emissions monitoring
information being reset, for example. This
may lead to the vehicle failing to meet the
requirements of the next emissions test
during the main inspection. Qualified specialist workshop

After an ai rbag has been deployed, have
the vehicle towed to the neares tqualified
specialist workshop, eve nifyour 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
0002deploys in front of the
steering wheel; front-passenger front air
bag 0003deploys 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
vehicle
The release time of the front air bags is
dependent upon the use of the seat belt.
Your vehicle has adaptive, two-stage front air
bags. In the event of a collision, the air bag
control unit evaluates the vehicle
deceleration. 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 threshold is exceeded within a
few milliseconds. The deployment of front-passenger front air
bag
0003is also influenced by the weight
category of the front passenger, which is
determined by the Occupant Classification
System (OCS) (Y page 47).
The lighter the passenger-side occupant, the
higher the vehicle deceleration rate required
(predicted at the start of the impact) for
second 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
situations where a low impact severity is
predicted. You will then be protected by the
fastened seat belt.
The front-passenger front air bag will only be
deployed if:
R the system, based on the OCS weight
sensor readings, detects that the front-
passenger seat is occupied
R the PASSENGER AIR BAG OFF indicator
lamp on the center console is not lit
(Y page 47)
R the air bag control unit predicts a high-
impact severity
Driver's knee bag Driver's knee bag
0002increases the driver's
protection against:
R knee injuries
R thigh injuries
R lower leg injuries 44
