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 possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also

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 recom-
mendations in some countries.
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-functioning
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 nec-
essary, that of the trailer before each journey.
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 b(
Ypage 35) indicator lamp lights up, or
you will see a corresponding message in the
display (
Ypage 185).
iDepending on the equipment, the bulb fail-
ure indicator can fail for all lamps with the
exception of the turn signal lamps.

Changing bulbs
Important safety notes
GDANGER
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.
GWARNING
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.
RAlways switch off the vehicle's lighting sys-
tem before changing a bulb.
This will prevent a short circuit.
RDo 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.
RDo not use a bulb that has been dropped or
that has scratches on its glass tube.
The bulb could explode.
ROnly use bulbs in closed lamps which have
been designed for this purpose.
ROnly use spare bulbs of the same type and
with the prescribed voltage
RProtect the bulbs from moisture when in use.
If the new bulb still does not light up, consult a
qualified specialist workshop.
RHave the LEDs and bulbs of the following
lamps changed at a qualified specialist work-
shop:
-the additional turn signals in the exterior
mirrors
-the high-mounted brake lamp
-LED daytime running lamps (Bi-Xenon
headlamps)
-Bi-Xenon lamps (Bi-Xenon headlamps)
-front fog lamps
If you require assistance changing bulbs, con-
sult a qualified specialist workshop.

Breaking-in notes
The first 1000 miles (1500 km)
New or replaced brake pads and brake disks
only reach their optimum braking effect after a
few 100 miles (a few 100 kilometers). Until then,
compensate for this by applying greater force to
the brake pedal.
For the service life and economy of your vehicle
it is crucial that you break in the engine with due
care.
RTherefore, protect the engine for the first
1000 miles (1500 km) by driving at varying
vehicle and engine speeds.
RAvoid overstraining the vehicle and high
engine speeds during this period, e.g. driving
at full throttle. Do not exceed Øof the max-
imum speed for each gear.
RDo not change down a gear manually in order to brake.
RTry to avoid depressing the accelerator pedal
beyond the point of resistance (kickdown).
RThe shift ranges 3,2or 1should only be
engaged when driving slowly, e.g. when driv-
ing in mountainous terrain.
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
iYou should also observe these notes on
breaking-in if the engine or parts of the drive
train on your vehicle have been replaced.
Driving
Important safety notes
GWARNING
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.
GWARNING
If the parking brake has not been fully
released when driving, the parking brake can:
Roverheat and cause a fire
Rlose its hold function.
There is a risk of fire and an accident. Release
the parking brake fully before driving off.
If you park the vehicle for more than
three weeks:
Rconnect the batteries to a trickle charger or
Rdisconnect the vehicle's starter battery or
Rswitch off the electrical system using the bat-
tery main switch (Ypage 118) and
Rdisconnect the vehicle's auxiliary battery
Otherwise, you need to check the battery's con-
dition of charge every 3 weeks, since standby
power consumption can drain the battery. If the
battery voltage is lower than 12.2 V, the battery
must be charged. Otherwise, the battery may be damaged by exhaustive discharging.
Be sure to observe the notes on disconnecting
and charging the batteries under "Battery"
(
Ypage 228). You can obtain information about
trickle chargers from a qualified specialist work-
shop.
