Important safety notes
G
WARNING
If you do not have the prescribed service/
maintenance work or any required repairs carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop. G
WARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, 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. 24
Introduction

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,
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. Oper-
ation is subject to the following two condi-
tions: 1) These devices may not cause harm-
ful interference, and 2) These devices must
accept any interference received, including
interference that may cause undesired oper-
ation. Changes or modifications not expressly approved by the party responsible for com-
pliance 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, includ- ing 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 diagnos-
tics connection in the vehicle. G
WARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed 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
sufficient clearance 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 equip-
ment on the 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 Introduction

SRS reduces the risk of vehicle occupants
coming into contact with parts of the vehi-
cle's interior in the event of an accident. It can
also reduce the forces to which vehicle occu-
pants are subjected during an accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, restraint system
components may be triggered unintentionally
or might not be triggered at all in the event of
an accident with a high rate of vehicle decel-
eration. There is an increased risk of injury,
possibly even fatal.
Have SRS checked and repaired immediately
at a qualified specialist workshop.
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 0075 SRS warning lamp in the instrument
cluster lights up when the ignition is switched on. It goes out no later than a few seconds
after the engine is started.
The SRS components are in operational read-
iness when the 0075SRS indicator lamp goes
out while the engine is running.
There is a malfunction if:
R the 0075 SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 0075SRS
warning lamp does not go out after a few
seconds
R the engine is running and the 0075SRS
warning lamp lights up again Triggering of Emergency Tensioning
Devices and air bags During the first stage of a collision, the air bag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air
bag control unit pre-emptively triggers the
Emergency Tensioning Device in the first
stage.
If there is an even higher rate of vehicle decel- eration or acceleration in a longitudinal direc-tion, the front air bags are also deployed.
Your vehicle has adaptive, two-stage front air bags. The air bag control unit evaluates vehi-cle deceleration or acceleration in the event
of a collision. In the first deployment stage,
the front air bag is filled with enough propel-
lant gas to reduce the risk of injuries. The
front air bag is fully deployed if a second
deployment threshold is reached within a few
milliseconds.
The Emergency Tensioning Device and air bag triggering thresholds are variable and are
adapted to the detected rate of deceleration
or acceleration of the vehicle. This process is
pre-emptive in nature. The triggering process must 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:
R the distribution of forces during the colli-
sion
R the collision angle
R the deformation characteristics of the vehi-
cle
R the characteristics of the object with which
the vehicle has collided
Factors that can only be seen and measured
after a collision has occurred do not play a Occupant safety
