Instrument clusterAt a glance
allows malfunctions to be detected in good
time.
When the ignition is switched on, the 0075
restraint system warning lamp in the instru-
ment cluster lights up. It goes out no later
than a few seconds after the vehicle is star-
ted. The components of the restraint system
are on standby.
A malfunction has occurred if the 0075
restraint system warning lamp:
R does not light up after the ignition is
switched on.
R does not switch off after a few seconds.
R goes out, but then lights up again, e.g. when
the engine is running. G
WARNING
If restraint system is malfunctioning, restraint system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible. Seat belts
Introduction Seat belts are the most effective means of
restricting the movement of vehicle occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of vehi- cle occupants coming into contact with parts
of the vehicle interior or being ejected from
the vehicle. Furthermore, the seat belt helps
to keep the vehicle occupant in the best posi- tion in relation to the air bag. The seat belt system comprises:
R Seat belts
R Emergency Tensioning Devices and seat
belt force limiters for the driver's and front-
passenger seat belts
On vehicles with two seats on the front-
passenger side, both seat belts on the
front-passenger side have an Emergency
Tensioning Device. Only the seat belt on the
outer front-passenger seat has a seat belt
force limiter.
The seat belt system only includes Emer-
gency Tensioning Devices and seat belt force
limiters for the driver and front passenger if
the vehicle is equipped with a driver's air bag.
If the seat belt is pulled out of the belt outlet quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be
extracted any further.
The Emergency Tensioning Device tightens
the seat belt in an accident, pulling the belt
close against the body. However it does not
pull the vehicle occupant back in the direction
of the backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the rout- ing of an incorrectly fastened seat belt.
When triggered, seat belt force limiters help
to reduce the force exerted by the seat belt on
the vehicle occupant.
The seat belt force limiters are synchronized
with the front air bags, which absorb part of
the deceleration force. This can reduce the
force exerted on the vehicle occupants during an accident.
! 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 anaccident, which will then need to be
replaced.
Vehicles with two seats on the front-
passenger side: the Emergency Tensioning
Device of the inner front-passenger seat is Occupant safety

As a result, they could:
R activate vehicle equipment and become
trapped, for example
R activate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung around the vehicle in the event of an accident or sud-
den steering or braking, thereby injuring vehi- cle occupants. There is a risk of an accident
and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals properly during
the journey, e.g. use a suitable animal trans-
port box. Driving safety systems
Overview
In this section, you will find information about the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
R ASR (A cceleration SkidControl)
R BAS (B rakeAssist System)
R EBD ( Electronic Brake Force Distribution)
R ESP ®
(E lectronic StabilityProgram) Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of accident nor over-
ride the laws of physics. Driving safety sys-
tems are merely aids designed to assist driv- ing. You are responsible for the distance to
the vehicle in front, for vehicle speed, braking in good time and for staying in your lane.
Always adapt your driving style to the prevail-
ing road and weather conditions and maintain a sufficient, safe distance from other road
users. Drive carefully.
The driving safety systems described can only
attain their maximum effectiveness when
there is optimum contact between the tires and the road can. Pay particular attention to
the information regarding tires, recommen-
ded minimum tire tread depth etc. under
"Wheels and tires" (Y page 284).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow
chains. This is the only way to get the full
benefit from the driving safety systems
described. ABS (Anti-lock Braking System)
Important safety notes Observe the important safety guidelines for
the driving safety system (Y
page 57). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid- ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems will
also fail, including driving safety systems.
Observe the information relating to the 0025
warning lamp (Y page 218).
ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when you only brake gently.
The yellow 0025warning lamp in the instru-
ment cluster lights up when the ignition is
switched on. The lamp goes out when the
engine starts running. Driving safety systems
57Safety Z
If you deactivate ASR:
R engine torque is not limited and the drive
wheels are able to spin. The spinning
wheels will then achieve a cutting effect for
better traction.
R traction control remains active through
brake intervention. If a drive wheel attains
its tire traction limit because one side of the
road is slippery, for example, that wheel is
braked. The traction is then increased in
this situation.
R active brake intervention by ESP ®
to
increase driving stability remains active.
The 0072 warning lamp in the instrument
cluster flashes when ESP ®
is intervening. BAS (Brake Assist System)
G
WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Vehicles without steering wheel buttons: if
the BAS driving safety system is malfunction-
ing, the 003Dwarning lamp lights up while the
engine is running (Y page 218).
BAS operates in emergency braking situa-
tions. If you depress the brake quickly, BAS
automatically increases the brake pressure,
thereby reducing the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. EBD (electronic brake force distribu-
tion) G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the risk of skidding and an accident. You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
EBD monitors and controls the brake pres-
sure to the rear wheels. This enables EBD to
improve handling during braking.
Observe the information on warning and indi- cator lamps (Y page 218). ESP
®
(Electronic Stability Program)
Important safety notes Observe the important safety guidelines for
the driving safety system (Y
page 57). G
WARNING
If ESP ®
is malfunctioning it will not provide
any vehicle stabilization. There is an increased
risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP ®
checked at a qualified specialist
workshop.
! Do not run the vehicle on a roller dyna-
mometer (e.g. for performance tests). If
you must operate the vehicle on a roller
dynamometer, please consult a qualified
specialist workshop in advance. You could
otherwise damage the drive train or the
brake system.
If ESP ®
is malfunctioning, the 0089warning
lamp lights up while the engine is running and
the engine power may be reduced
(Y page 218).
Only use wheels with the recommended tire
sizes. Only then will ESP ®
function properly.
Crosswind Assist Crosswind Assist does not work if ESP
®
is
deactivated or disabled because of a mal-
function. Driving safety systems

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of your vehicle that were available at the time of going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions
relevant to safety.
Read the information on qualified specialist
workshops (Y page 25). Exterior lighting
Important safety notes
For reasons of safety, we recommend that
you drive with the lights switched on even
during the daytime. There may be differences
in operation due to legal requirements and
voluntary recommendations in some coun-
tries. Bulb failure indicator
The bulb failure indicator is only an aid. You
are responsible for the proper functioning of
the vehicle lighting. Insufficient or non-func-
tioning vehicle lighting puts the operating
safety of the vehicle at risk.
For this reason, check the condition and func-
tion of your vehicle's lighting system and, if
necessary, that of the trailer before each jour- ney.
The bulb failure indicator monitors all of the
exterior lighting lamps, except the perimeter
lamp and the trailer lighting. If a bulb fails,
either the 0049(Ypage 35) indicator lamp
lights up, or you will see a corresponding
message in the display (Y page 208).
i Depending on the equipment, the bulb
failure indicator can fail for all lamps with
the exception of the turn signal lamps. Light switch

Exterior lightingLights and windshield wipers
Motion detector
G
WARNING
The motion detector sends the invisible infra- red radiation emitted by LEDs (light emitting
diodes).
These LEDs are classified as class 1M lasers
and can damage the retina if you:
R look directly into the unfiltered laser beam
of the motion detector for an extended
period
R look directly into the laser beam of the
motion detector using optical instruments,
e.g. eyeglasses or a magnifying glass.
There is a risk of injury.
Never look directly into the motion detector.
The cargo compartment lighting is also
switched on by the motion detector in the
cargo compartment of Cargo Vans equipped
with this feature.
If the motion detector detects a movement in the cargo compartment when the vehicle is
stationary, the cargo compartment lighting
switches on for approximately two minutes.
The cargo compartment lighting can be
switched on by the motion detector within
four seconds if:
R the rear interior light switch (Y page 98) is
set to automatic control.
R the vehicle is stationary, the parking brake
is applied and the brake pedal is not being
depressed
Or
R the selector lever is in position Pon vehi-
cles with automatic transmission and the
brake pedal is not being depressed and
R the vehicle has not been locked from the
outside using the key
The motion detector switches off automati-
cally if no change is detected in the vehicle for
several hours, e.g. if a door is opened, if the
ignition key is turned, etc. This prevents the
battery from becoming discharged. Changing bulbs
Important safety notes
G
DANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop. G
WARNING
Bulbs, lamps and connectors can get very hot when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before changing a bulb.
! Make sure the bulbs are always securely
installed.
If your vehicle is equipped with Bi-Xenon
bulbs, you can recognize this by the following: the cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the low-beam headlamps must be
switched on before starting the engine.
The bulbs and lamps are an essential compo- nent of vehicle safety. You must therefore
make sure that these function correctly at all
times. Have the headlamp setting checked
regularly.
R Always switch off the vehicle's lighting sys-
tem before changing a bulb.
This will prevent a short circuit.
R Do not touch the glass tube of new bulbs
with your bare hands. Always use a clean,
lint-free cloth or only touch the base of the bulb when installing.
Even minor contamination can burn into
the glass surface and reduce the service life
of the bulbs. Changing bulbs
