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 variation sare possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to system sand function srelevantt o

Breaking-in notes
Important safetyn otes
In certain drivingand drivingsafetysystems, the
sensors adjust automatically while acertain dis-
tance is being driven after the vehicle has been
delivered or after repairs. Full system effective- ness is not reached until the end of this teach-in
procedure.
New or replaced brake pads and brake discs
only reach their optimal brakin geffecta fter a
few hundred kilometers of driving. Until then,
compensat efor this by applying greater forcet o
the brake pedal.
The first 1000 miles (1500 km)
For the servicel ife and economy of your vehicle
it is crucial that you break in the engin ewith due
care.
RTherefore, protect the engin efor the first
1000m iles (1500k m) by drivingatv arying
vehicle and engin espeeds.
RAvoid overstraining the vehicle and high
engin espeeds during this period, e.g. driving
at full throttle. Do not exceed Øof the max-
imum speed for each gear.
RDo not change down agear manually in order
to brake.
RTry to avoid depressingt he accelerator pedal
beyond the point of resistance (kickdown).
After 1000m iles (1500km), you can increase
the engin espeed gradually and accelerate the
vehicle to full speed.
iYou should also observet hesenotes on
breaking-in if the engin eorparts of the drive
train on your vehicle have been replaced.

Important safetyn otes
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignit eifinc ontact with the exhaust system or
parts of the engin ethat heat up. There is arisk
of fire.
Carry out regular checks to make sure that
ther eare no flammable foreign materials in
the engin ecompartmen torinthe exhaust
system.
GWARNING
If you switc hoff the ignition while driving,
safety-relevant function sare 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 efforttos teer and brake. There is arisk
of an accident.
Do not switc hoff the ignition while driving.
GWARNING
If the parkin gbrake has not been fully
released when driving, the parkin gbrake can:
Roverheat and cause afire
Rlose its hold function.
There is arisk of fire and an accident. Release
the parkin gbrake fully before drivingo ff.
!Warm up the enginequickly. Do not use the
engine's full performanc euntil it has reached
operatin gtemperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is sta-
tionary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train.
