39 Getting started
Driving


Do not fasten a seat belt around a per-
son and another object at the same
time.


Check your seat belt during travel to
ensure that it is properly positioned.


Ensure that the seat belt is always fit-
ted snugly. You should avoid wearing
bulky clothing, such as winter coats,
when traveling in the vehicle.
Starting the engine
Gearshift pattern for automatic
transmissionP Park position with selector lever lock
R Reverse gear
N Neutral
D Drive position
More information can be found in the
“Controls in detail” section (
page 137).

Make sure that the gear selector lever
is set to P.
Warning!
G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced by
an authorized Mercedes-Benz Center.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive with at least one window
fully open.

152 Controls in detailAutomatic climate controlAir recirculation mode

ature is below approximately 41°F
(5 °C)


after five minutes if the air conditioner
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.
Warning!
G

41°F (5°C), only switch to air recirculation
mode for short periods to prevent window
fogging.
iIf you keep button
,
pressed, the
side windows will close.
The air recirculation mode is activated
automatically


at high outside temperatures


if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases, for example in a
tunnel
If you have turned off the air condition-
er (page 155) or the outside
temperature is below 41°F (5°C), the
air recirculation mode will not switch

The air conditioning 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 AC
OFF
button on the automatic
climate control panel starts to blink,
this indicates that the air conditioning
is losing refrigerant. The compressor
has turned itself off. The air condition-
ing cannot be turned on again.


Have the air conditioner checked at
the nearest authorized
Mercedes-Benz Center.

184 Controls in detailDriving systemsVehicle level control
Your vehicle automatically adjusts its ride
height to:

reduce fuel consumption


increase vehicle safety
The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed:


With increasing speed, ride height is re-
duced by up to approximately one inch
(25 mm).


With decreasing speed, the ride height
is again raised to the selected vehicle
level.Select the level 1 and 2 settings only when
required by current driving conditions.
Otherwise:


Fuel consumption may increase.


Handling may be impaired.iThese height adjustments are so small
that you may not notice any change.
Warning!
