The air recirculation mode is deactivated
automatically:


after five minutes if the outside temper-
ature is below approximately 41°F
(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
(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

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

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 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.

The red SRS indicator lamp lights
up while driving.
There is a malfunction in the restraint sys-
tems. The airbags or emergency tensioning
device (ETDs) could deploy unexpectedly or
fail to activate in an accident.

Drive with added caution to the

cated as outlined above, the SRS may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked. Otherwise the SRS

There is insufficient brake fluid in the reser-
voir.

Risk of accident! Carefully stop the
vehicle and notify an authorized
Mercedes-Benz Center. Do not add
brake fluid! This will not solve the
problem.
Warning!
G
Driving with the brake warning lamp illumi-
nated can result in an accident. Have your
brake system checked immediately if the
brake warning lamp stays on. Don’t add
brake fluid before checking the brake sys-
tem.
Overfilling the brake fluid reservoir can re-
sult in spilling brake fluid on hot engine
parts and the brake fluid catching fire. You
can be seriously burned.
!If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks.

200 Practical hintsWhat to do if …?When the low engine oil level warning lamp
does not go out after starting the engine,
or comes on while the engine is running
and at operating temperature, the engine
oil level has dropped to approximately the
minimum mark on the dipstick.When this occurs, the warning lamp will
first come on intermittently and then stay
on if the oil level drops further.
If no oil leaks are noted, continue to drive
to the nearest service station where the
engine oil should be topped to the “full”
mark on the dipstick with an approved oil.Problem

Suggested solution
_
The red telescoping steering
column* warning lamp remains
lit after starting the engine.

1/3 of
total reservoir capacity.

Add washer fluid (
page 179).
N
The yellow low engine oil level
warning lamp remains lit after
starting the engine or lights up
while driving.
The engine oil level is too low.

Check the engine oil level
(page 172) and add oil as required
(page 175).

If you must add engine oil frequently,
have the engine checked for possible
leaks.!The low engine oil level warning light
should not be ignored. Extended driv-
ing with the light illuminated could re-
sult in serious engine damage that is
not covered by the Mercedes-Benz
Limited Warranty.
