or visibility is poor. There is arisk of an acci-
dent.
You should therefore ensure in this and simi-
lar situations that the vehicle is visible from
the rear in accordance with the relevant
national regulations, by using the warning tri-
angle, for instance.

Climate control

RIf you wish to use the driver's side settings on
the front-passenger side and, for vehicles
with rear-compartment air conditioning, for
the rear compartment as well,use the "Syn-
chronization" function. The indicator lamp in
the 0 button comes on when the function
is switched on.
RAfter long journeys, you can use the residual
heat of the engine to heat the stationary vehi-
cle. The residual heat function can only be
switched on or off whilet he ignition is
switched off. The indicator lamp in the Ì
button comes on when the function is
switched on.
Approximatel y60minutes after parking the
vehicle,a utomatic climate control can switch on
automatically ,depending on the outsid etem-
perature. The vehicle is then ventilated for about
30 minutes at low fan setting and the automatic
climate control system is dried out.
During automatic engine switch-off, the climate control system only operates at areduced capa-
city. Further information on the automatic
engine switch-off can be found under "ECO
start/stop function" (
Ypage 122).
Information on rear-compartment air
conditioning
Vehicles with TEMPMATIC air-conditioning
system
Switch the rear-compartment air-conditioning
system on and off using the TEMPMATIC air-
conditioning system control panel. When you
switch on the rear-compartment heating, the
settings for temperature ,airflow and air distri-
bution are automatically adopted on the control
panel for the rear-compartment heating.
The indicator lamp in the /button comes on
when the rear-compartment air-conditioning is
switched on (
Ypage 108).
Vehicles with automatic climate control
To operate the rear-compartment air condition-
ing, use the control panel of the automatic cli-
mate control system. When you switch on the
rear-compartment air conditioning, you can set
the temperature and airflow separately on the
control panel .The airflow setting is automati-
cally adopted for the rear-compartment air con-
ditioning. When automatic climate control is in
à automatic mode, the air distribution of the
rear-compartment air conditioning is also auto-
matically adjusted. When you set the temperature and airflow of the
rear-compartment air conditioning, the indica-
tor lamp of the
/button (
Ypage 109)
flashes. When the rear-compartment air condi-
tioning is switched on, the indicator lamp on
the / button lights up.
For optimum climate control, set the tempera-
ture to 72 ‡(22 †) and switch on Ãauto-
matic mode. Only change the temperature in
small increments.

iAt high interior temperatures, the blower is
also switched on when adoor is opened. This
means that slightly cooled air enters the vehi-

General notes
Only vehicles with automatic climate control
have the residual heat function.
Once the engine is switched off, it is possible to
make use of the residual heat of the engine to
continue heating or ventilating the front com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.

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.
Driving
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.
