ting started” section.
Rear view mirror
Automatic antiglare rear view mirror
The reflection brightness of the exterior 
rear view mirror on the driver’s side and 
the inside rear view mirror will respond au-
tomatically to glare when
the ignition is switched on, and
incoming light from headlamps falls on 
the sensor in the inside rear view mir-
ror.
The rear view mirror will not react if
reverse gear is engaged
the interior lighting is turned on
the wind screen is installed 
(page 134)
Warning!
G
The automatic antiglare function does not 
react if incoming light is not aimed directly 
at sensors in the inside rear view mirror.
The inside rear view mirror and the exterior 
rear view mirror on the driver’s side do not 
react, for example, if the wind screen is in-
stalled.
Glare can endanger you and others.
Warning!

In the case of an accident, liquid electrolyte 
may escape from the mirror housing if the 
mirror glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with 
eyes, skin, clothing, or the respiratory sys-
tem. In case it does, immediately flush af-
fected area with water, and seek medical 
help if necessary.

(5 °C)
after five minutes if the air conditioning 
is turned off
after 30 minutes if the outside temper-
ature is above approximately 41°F

At outside temperatures above 79°F 
(26 °C), the system will not automatically 
switch back to outside air. A quantity of 
outside air is added after approximately 
30 minutes.
Rear window defroster
The rear window defroster uses a large 
amount of power. To keep the battery 
drain to a minimum, switch off the defrost-
er as soon as the rear window is clear. The 
defroster is automatically deactivated af-

Any accumulation of snow and ice should be 
removed from the rear window before driv-
ing. Visibility could otherwise be impaired, 
endangering you and others.!If the rear window defroster switches 
off too soon and the indicator lamp 
starts blinking, this means that too 
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system 
responds automatically by deactivating 
the rear window defroster. 
As soon as the battery has sufficient 
voltage, the rear window defroster au-
tomatically turns itself back on.
iCondensation may drip out from under-
neath the vehicle. This is normal and 
not an indication of a malfunction.
Warning!

While driving, deactivate the air conditioning 
only temporarily to prevent window fogging.
