WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine. G
WARNING
If the steering wheel is unlocked while the
vehicle is in motion, it could change position
unexpectedly. This could cause you to lose
control of the vehicle. There is a risk of an
accident.
Before starting off, make sure the steering
wheel is locked. Never unlock the steering
wheel while the vehicle is in motion. G
WARNING
Children could injure themselves if they
adjust the steering wheel. There is a risk of
injury. When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.

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

WARNING
When the light switch is set to 0058, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
0058.
Automatic headlamp mode is only a driving
aid. You are responsible for the vehicle light-
ing at all times.
Depending on ambient light, the rain and light sensor automatically switches on the parking lamps, low-beam headlamps and the license
plate lamp. This excludes weather-related
impairments to visibility, such as snow, fog or
spray.
If there is fog, snow or spray, turn the light
switch quickly from 0058to0058. You could
otherwise briefly interrupt operation of the
headlamps.

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

Windshield wipers
Switching the windshield wiper
on/off
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when the windshield is dry.
If it is necessary to switch on the windshield wipers in dry weather conditions, always
use washer fluid when operating the wind-
shield wipers.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.
! Vehicles with rain/light sensor:
Switch the wipers off in dry weather. Oth-
erwise, dirt or optical effects may cause
undesired windshield wiper sweeps. This
could then damage the windshield wiper
blades or scratch the windshield.
The windshield will no longer be wiped prop-
erly if the wiper blades are worn. Replace the wiper blades twice a year (Y page 108), ide-
ally in spring and fall. Combination switch X
Turn the key to position 1or 2in the ignition
lock.
X Turn the combination switch in the direc-
tion of arrow 0044to the appropriate setting
depending on the intensity of the rain.
X Single wipe: push the combination switch
briefly to the pressure point in the direction
of arrow 0043.
X To wipe with washer fluid: press the com-
bination switch beyond the pressure point
in the direction of arrow 0043.
The detent positions of the combination
switch correspond to the following wiper
speeds:
0W indshield wipers off
II ntermittent wipe
II Normal wipe
III Rapid wipe
i Canada only:
If the windshield wipers are switched on
and you stop the vehicle, the windshield
wiper speed is reduced. For example, if you have selected level IIand stop the vehicle,
wiping continues with intermittent wipe
while the vehicle is stationary. If intermit-
tent wipe is selected, the intervals become
longer.
Vehicles with a rain and light sensor:
you can use level Ias the universal setting.
The rain and light sensor sets the appropri-
ate wiping frequency automatically,
according to the intensity of the rain. When
you stop the vehicle, levels IIIand IIare
switched down to level Iautomatically.
The windshield wiper will return to the orig- inal level when you drive faster than 5 mph
(8 km/h).
You can adjust the sensitivity of the rain and
light sensor using the on-board computer
(Y page 193).
Information on checking the washer fluid
level can be found in the "Maintenance and
care" section (Y page 255). Windshield wipers
