Auto-dimming mirror
The reflection brightness of the exterior

the interior rear view mirror will respond 
automatically to glare when
the ignition is switched on, and
incoming light from headlamps falls on 
the sensor in the interior rear view mir-
ror
The rear view mirror will not react if
reverse gear is engaged
the interior lighting is turned on
Warning!
G
The auto-dimming function does not react if 
incoming light is not aimed directly at sen-
sors in the interior rear view mirror.
The interior rear view mirror does not react, 
for example, if the rear window sunshade is 
in raised position.
Glare can endanger you and others.Warning!
G
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 respiratory system. 
In case it does, immediately flush affected 
area with water, and seek medical help if 
necessary.

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-
ter approximately 6 to 17 minutes of oper-
ation depending on the outside 
temperature.
Activating
Press buttonF (
page 198) or 
(
page 210) or1(
page 199) 
or (
page 211) on the respective 
climate control panel.
The indicator lamp on the button 
comes on.Deactivating
Press buttonF or1 again.
The indicator lamp on the button goes 
out.Warning!
G
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 flashing, 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 
automatically turns itself back on.

200 Controls in detailDual-zone automatic climate controlThe climate control is operational whenev-
er the engine is running. You can operate 
the climate control system in either the au-
tomatic or manual mode. The system cools 
or heats the interior depending on the se-
lected interior temperature and the cur-
rent outside temperature.Nearly all dust particles, pollutants and 
odors are filtered out before outside air en-
ters the passenger compartment through 
the air distribution system.
The air conditioning will not engage (no 
cooling) if the AC
OFF
 mode is activated or 
AC mode is deactivated (
page 206).
Warning!
G
When operating the climate control, the air 
that enters the passenger compartment 
through the air vents in the footwell can be 
very hot or very cold (depending on the set 
temperature). This may cause burns or frost-
bite to unprotected skin in the immediate 
area of the air vents. Always keep sufficient 
distance between unprotected parts of the 
body and the footwell air vents. If necessary 
change the air flow using the air distribution 
controls (
page 198) to direct the air away 
from the footwell air vents.
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up, 
impairing visibility and endangering you and 
others.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval. A 
clogged filter will reduce the air volume 
to the interior.
If the vehicle interior is hot, ventilate 
the interior before driving off.
Keep the air intake grille in front of the 
windshield free of snow and debris.
Do not obstruct air flow by placing ob-
jects on the air flow-through exhaust 
slots below the rear window.

Use temperature controls1 and6 
(page 198) or (

ly adjust the air temperature on each side 
of the passenger compartment. You 
should raise or lower the temperature set-
ting in small increments, preferably start-
ing at 72°F (22°C).
Increasing
Turn the temperature control1 or6 
(page 198) or (

The climate control system will corre-
spondingly adjust the interior air tem-
perature.

air distribution. 
iWhen the air conditioning is switched 
off, the outside air supply and circula-
tion are also switched off. Only choose 
this setting for a short time. Otherwise 
the windows could fog up.
