high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake.
● If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector
lever to position P (automatic
transmission type A) / N
(automatic transmission type B). On an uphill slope, turn the
front wheels away from the
kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position P (automatic transmission type
A) / N (automatic transmission
type B). Turn the front wheels
towards the kerb.

radio remote control.
Activate the anti-theft alarm
system 3 37.
● The engine cooling fans may run
after the engine has been
switched off 3 213.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.

9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the

The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore,
condensation may form and drip from
under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons.
