is turned off


after 30 minutes if the outside temper-
ature is above approximately 41°F
(5°C)
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-
ter approximately 6 to 17 minutes of oper-
ation depending on the outside
temperature.
Activating

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.

Air conditioner
The air conditioner is operational while the
engine is running and cools the interior air
to the temperature set by the operator.

The air conditioner 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.
!If the air conditioner cannot be turned
on again, this indicates that the air con-
ditioner is losing refrigerant. The com-
pressor has turned itself off.
Have the air conditioner checked at the
nearest authorized Mercedes-Benz
Center.

Solar panel*
Combined with the panorama slid-
ing/pop-up roof a solar panel is available.
The solar cells convert natural light into
electrical energy. When the engine is
switched off, the energy generated auto-
matically switches on the ventilation fan.
The constant air flow creates a cooler tem-
perature for cars parked in the sunlight.
The air flow depends on the intensity of the
solar radiation. The ventilation starts 2
minutes after switching off the engine.

266 OperationEngine compartmentBattery
Your vehicle is equipped with two batter-
ies:

Auxiliary battery (located in the engine
compartment).


Main battery (starter and electrical
consumers; located in the trunk).
These batteries should always be suffi-
ciently charged in order to achieve their
rated service life.
If you use your vehicle mostly for short dis-
tance trips, you will need to have the bat-
tery charge checked more frequently.
When replacing batteries, always use bat-
teries approved by Mercedes-Benz.
If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized Mercedes-Benz Center about
steps you need to observe.Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
G
Observe all safety instructions
and precautions when handling
automotive batteries.
A
Risk of explosion
D
Keep flames or sparks away
from battery. Do not smoke.
B
Battery acid is caustic. Do not
allow it to come into contact
with skin, eyes or clothing.
In case it does, immediately
flush affected area with clear
water and seek medical help if
necessary.
E
Wear eye protection.
C
Keep children away.
F
Follow the instructions in this
Operator's Manual.
