refrigerant. Repairs should always be performed by a
qualified technician, and refrigerant should be collected
in a recovery system for recycling.

Rear window defroster
Turn the electronic key in starter switch to position 2.

Press the F button in the control panel of the
automatic air conditioner. The indicator lamp in the
button illuminates.
To ca nc el:
Press the F button in the control panel of the
automatic air conditioner. The indicator lamp in the
button goes out.
Note:
Heavy accumulation of snow and ice should be removed
before activating the defroster. The rear window defroster uses a large amount of power.
To keep the battery drain to a minimum, turn off the
defroster as soon as the rear window is clear.
The defroster is automatically turned off after
approximately 6–23 minutes of operation depending on
the outside temperature and vehicle speed.
If several power consumers are turned on
simultaneously, or the battery is only partially charged,
it is possible that the defroster will automatically turn
itself off. When this happens, the indicator lamp inside
the switch starts blinking.
As soon as the battery has sufficient voltage, the
defroster automatically turns itself back on.

cluster displayPractical hints Car care Index Important!
If the electronic key is left in the starter switch
position 0 for an extended period of time, it can no
longer be turned in the lock. In this case, remove
electronic key from starter switch and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
starter switch. Do not leave the electronic key in starter
switch position 0.Notes:
A warning sounds when the driver’s door is opened
with the electronic key in starter switch position 1 or 0.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example:
Heated seats, rear window defroster. In addition, the
automatic climate air volume control should be set to
the lowest position.

•Do not forget, the engine can be started by anyone if
a KEYLESS-GO-card is left inside the vehicle.
•To be able to operate the vehicle in the case of a
malfunction in the KEYLESS-GO-system (e.g. strong
radio frequency disturbance), we recommend that
you carry the electronic key plus mechanical key
with you and keep them in a safe place so that they
are always handy. Never leave the electronic key in
the vehicle.
•To avoid radio transmission interference, never store
the KEYLESS-GO-card together with other electronic
items (e.g. cellular telephones, other KEYLESS-GO-
cards) or metallic objects (e.g. coins, metal foil).Notes:
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
