Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Please read the information on qualified
specialist workshops (Y page 23).Occupant safety
Overview of occupant safety
In this section, you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint system consists of:
R seat belts
R child restraint systems
Additional protection is provided by:
R SRS (Supplemental Restrain tSystem)
R NECK-PRO head restraints
R Airb ag system component swith:
- PASSENGER AIR BAG ON/OFF indicator
lamp 2
- front-passenger seat with Occupant
Classification System (OCS)
The differen tair bag systems work
independently of each other. The protective
functions of the system work in conjunction
with each other. Not all air bags are deployed
in an accident. G
WARNING
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead to the restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deploymen tis exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
i See "Children in the vehicle"
(Y page 53) for more information on
infants and children traveling with you in
the vehicle and restraints for infants and
children. SRS (Supplemental Restraint System)
Introduction SRS consists of:
R
the 0019 SRS warning lamp
R air bags
R air bag control unit (with crash sensors)
R Emergency Tensioning Devices
R belt force limiters
SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS warning lamp 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
0019 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.
2 The PASSENGER AIR BAG ON indicator lamp has no function. When switching on the ignition, it lights up
briefly and then goes out again. 36

mode
G
WARNING
The SPORT handling mode should not be
switched on during normal driving.
Switching on the SPORT handling mode will
result in the following:
R no restriction to the engine torque
R system supported traction control is
limited
The SPORT handling mode is designed for
driving on closed tracks when the vehicle's
own natural oversteer and understeer
characteristics are desired and requires a
highly skilled and experienced driver able to
handle these critical driving situations. You could lose control of your vehicle and
cause an accident.
Please be aware of these limits when you
switch on the SPORT handling mode.
Do not switch on the SPORT handling when a
spare wheel is mounted.
ESP ®
is activated automatically when the
engine is started.
i Vehicles with ECO start/stop function:
the ECO start/stop function switches the
engine off automatically when the vehicle
comes to a stop. The engine starts
automatically when the driver wants to pull
away again. ESP ®
remains in its previously
selected status. Example: if ESP ®
was
deactivated before the engin ewas
switched off, ESP ®
remains deactivated
when the engine is switched on again.
It may be best to activate SPORT handling
mode in the following situations:
R when using snow chains
R in deep snow
R on sand or gravel G
WARNING
Switch off the SPORT handling mode and
switch on the ESP ®
immediately if the
aforementioned circumstances do no tapply
anymore. Otherwise the SPORT handling
mode will only stabilize the vehicle to a limited
extent when it is starting to skid or a wheel is
spinning.
When SPORT handling mode is activated:
R ESP ®
only improves driving stability to a
limited degree.
R engine torque is only restricted to a limited
degree, and the drive wheels are able to
spin. The spinning wheels produce a
cutting effect for better traction.
R traction control is still activated.
R ESP ®
still provides support when you brake
firmly. 60

Important safety notes
G
WARNING
When leaving the vehicle, always remove the
SmartKey from the ignition lock. Always take
the SmartKey with you and lock the vehicle.
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system, and do not give them access
to an unlocked vehicle. Achild's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. They could:
R injure themselves on vehicle parts
R be seriously or fatally injured by extreme
heat or cold
R injure themselves or have an accident with
vehicle equipment that may still be in
operation even after the SmartKey has
been removed from the ignition, such as the
seat adjustment, steering wheel
adjustment or memory function.
If children open a door, they could cause
severe or even fatal injury to other persons; if
they get out of the vehicle, they could injure
themselves when doing so or be seriously or
even fatally injured by any passing traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very hot, and a child could be burned on these
parts.
G
WARNING
If a key ring is too heavy or too large, the
weight acting on the key could cause it to turn
in the ignition lock or catch on the steering
wheel. This could cause the engine to be
switched off suddenly. You may lose control
of the vehicle and cause an accident. Do not
attach any heavy or large key rings to the key
that is inserted in the ignition. General notes
If you cannot lock or unlock the vehicle with
the SmartKey, either the battery in the
SmartKey is discharged, the SmartKey is
faulty or the starter battery is discharged.
X Check the battery in the SmartKey and
replace it if necessary (Y page 71).
X Unlock the driver's door using the
mechanical key (Y page 76).
X Lock the vehicle using the mechanical key
(Y page 76).
X Have the starter battery and the battery
contacts checked at a qualified specialist
workshop.
If the SmartKey is faulty, contact Roadside
Assistance or a qualified specialist workshop. SmartKey functions
