As a supplement to the heating and
ventilation system, the air conditioning
system cools and dehumidifies (dries)
inflowing air.
If cooling or dehumidification is not
desired, switch off cooling in order to save
fuel.
Cooling switches off automatically at low
outside temperatures.

Only operate with the engine and fan
running. Activate and deactivate with

When cooling is active (AC compressor) the
air is cooled and dehumid ified. If cooling or
dehumidification is not desired, switch off
cooling in order to save fuel.
Cooling switches off automatically at low

Driving and operation
Driving hintsThe first 1000 km
Drive your vehicle at various speeds. Do
not use full throttle. Never allow the engine
to labour at low revs.
Drive moderately. In all gears, only depress
the accelerator pedal around
3/4 of the way
down.
Do not drive faster than three quarters of
maximum speed.
Do not brake unnecessarily hard for the
first 200 km.
During the first drive smoke may develop
because of wax and oil evaporating on the
exhaust system. Park the vehicle in the
open for a while after the first drive and
avoid inhaling the fumes.
Fuel and engine oil consumption is higher
than normal during the running-in period.
Never coast with engine not running
Many units will not function in this situation
(e.g. brake servo unit, power steering 3).
Driving in this manner is a danger to
yourself and others. Brake servo unit
When the engine is not running, the brake
servo unit is no longer effective once the
brake pedal has been depressed once or
twice. Braking effect is not reduced, but
significantly greater force is required for
braking.
Electric power steering
3
If the power assisted steering fails when
being towed with the engine switched off,
the vehicle can still be steered, but
considerably more force is required.
Driving in mountainous terrain or with a
trailer/caravan
The cooling fan is elec trically operated. Its
cooling power is therefore independent of
the engine speed.
Since a considerable amount of heat is
generated at high engine speeds and less
at slower speeds, do not shift down when
climbing hills whilst the vehicle is still coping
with the gradient in the higher gear. Driving with a roof load
Do not exceed the permissible roof load
3
226. For reasons of safety, distribute the
load evenly and secure it properly with
retaining straps. Adjust tyre pressure to
load conditions. Do not drive faster
than 120 km/h. Check and retighten the
straps frequently. Observe country-specific
regulations.
Switching off the engine
When you switch off, fans in the engine
compartment may continue running for a
time to cool the engine.
If the engine temperature is very high, e.g.
after driving in mountainous terrain: allow
the engine to idle for approximately two
minutes in order to prevent heat
accumulation.
Vehicles with turbocharged engine
3
After running at high engine speeds or 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.
