The air conditioning is operational while
the engine is running and cools the interior
air to the temperature set by the operator.Deactivating
It is possible to deactivate the air condi-
tioning (cooling) function of the automatic
climate control system. The air in the vehi-

The air conditioning uses the refrigerant
R134A. This refrigerant is free of CFCs
which are harmful to the ozone layer.
iCondensation may drip out from under-
neath the vehicle. This is normal and
not an indication of a malfunction.
iUnder certain circumstances, e.g.
when the fuel system is too hot and
needs to be cooled, the cooling switch-
es on again automatically. The red lamp
on the ± button the automatic cli-
mate control panel flashes.
After cooling the fuel system sufficient-
ly, the air conditioning switches off
again and the red lamp stops flashing.
!If you press the ± button on the au-
tomatic climate control panel and it
starts to flash, this indicates that the
air conditioning is losing refrigerant.
The compressor has turned off. The air
conditioning cannot be turned on
again.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.

Stop the vehicle in a safe location and turn off the en-
gine.

Only start the engine again after the message disap-
pears. You could otherwise damage the engine.
Warning!

Driving when your engine is badly over-
heated can cause some fluids which may
have leaked into the engine compartment to
catch fire. You could be seriously burned.
Steam from an overheated engine can cause
serious burns and can occur just by opening
the hood. Stay away from the engine if you
see or hear steam coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.

Batteries
Warning!
G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof batteries only to avoid the
risk of acid burns in the event of an
accident.
Warning!
G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. The same applies if
battery is disconnected. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is in-
creased! Adjust your driving style according-
ly. For more information, see
“Electrohydraulic brake system”
(page 84).
