climate control
Below, you can find a number of notes and
recommendations to help you use 3-zone
automatic climate control optimally. R Activate automatic mode. All basic functions
are controlled automatically. The indicator
lamp in the à switch comes on when the
function is switched on.
R Switch on the cooling with air dehumidifica-
tion function. The indicator lamp in the
¿ button comes on when the function is
switched on. R
Set the temperature to
72 ‡ (22 †) for
both sides. Only change the temperature in
small increments.
R Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again. The indicator lamp in the ¬ button
comes on when the function is switched on.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could other-
wise fog up as no fresh air is drawn into the
vehicle in air-recirculation mode. The indica-
tor lamp in the h button comes on when
the function is switched on. 116

midification function on/off
Important safety notes The cooling with air dehumidification function
of the air conditioning or automatic climate
control is only available when the engine is
running. The air inside the vehicle is cooled
and dehumidified according to the tempera-
ture selected.
Condensation may appear on the underside of
the vehicle when in cooling mode. This is nor-
mal and not a sign that there is a malfunction.
If you switch off the "Cooling with air dehumid-
ification" function, the air inside the vehicle
will not be cooled (in warm weather) or dehu-
midified. Therefore, only switch off the "Cool-
ing with air dehumidification" function briefly.

Important safety notes
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of
this teach-in procedure.
New or replaced brake pads and brake discs
only reach their optimal braking effect after a
few hundred kilometers of driving. Until then,
compensate for this by applying greater force
to the brake pedal. The first 1000 miles (1500 km)
For the service life and economy of your vehi-
cle it is crucial that you break in the engine
with due care.
R Therefore, protect the engine for the first
1000 miles (1500 km

) by driving at varying
vehicle and engine speeds.
R Avoid overstraining the vehicle and high
engine speeds during this period, e.g. driv-
ing at full throttle. Do not exceed Ø of the
permissible maximum speed for each gear.
R Do not change down a gear manually in
order to brake.
R Try to avoid depressing the accelerator
pedal beyond the pressure point (kickdown).
After 1000 miles (1500 km), you can increase
the engine speed gradually and accelerate the
vehicle to full speed.
i You 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
G
WARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system
or parts of the engine that heat up. There is
a risk of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system. G
WARNING
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. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake
can:
R overheat and cause a fire
R lose its hold function.
There is a risk of fire and an accident.
Release the parking brake fully before driv-
ing off.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift the automatic transmission to the
desired drive position when the vehicle is
stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery roads.
You could otherwise damage the drive train. 126
