Parking
GWarning!
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system. These materials could be
ignited and cause a vehicle fire.
Vehicle movement may result in serious
personal injury or damage to the vehicle or
vehicle drivetrain. Therefore, always do the
following before turning off the engine and
leaving the vehicle:
R Keep right foot on the brake pedal.
R Engage the parking brake.
R Shift the automatic transmission into park
position P.
R Slowly release the brake pedal.
R When parked on an incline, always turn the
front wheels towards the road curb.
R Turn the SmartKey in the starter switch to
position 0 and remove the SmartKey from
the starter switch, or press the KEYLESS-
GO start/stop button.
R Take the SmartKey with you and lock the
vehicle when leaving.
Parking brake GWarning!
Engaging the parking brake while the vehicle
is in motion can cause the rear wheels to lock
up. You could lose control of the vehicle and
cause an accident. In addition, the vehicle’s
brake lights do not light up when the parking
brake is engaged.
GWarning!
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it with
you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children could
release the parking brake and/or shift the
automatic transmission out of park position
P , either of which could result in an accident
and/or serious personal injury.

Your vehicle is equipped with either of the following climate control systems:
Climate control (Y page 167)3-zone automatic climate control
USA only (Y page 173)
Canada only (Y page 175)
The climate control combines an automatic
heating and ventilation system with a cooling
system. You can adjust the automatic
climate control separately for the driver’s
and passenger side.
The 3-zone automatic climate control
combines an automatic heating and
ventilation system with a cooling system.
You can adjust the 3-zone automatic climate
control separately for each zone in the
vehicle.

The climate control is operational whenever
the engine is running. You can operate the
climate control system in either the
automatic or manual mode. The system cools
or heats the interior depending on the
selected interior temperature and the current
outside temperature.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.GWarning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
The air conditioning will not engage (no
cooling) if the A/C mode is deactivated
( Y page 169).
GWarning!
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
Keep the air intake grille in front of the
windshield free of snow and debris.
i If the vehicle interior is hot, ventilate the
interior before driving off, see “Summer
opening feature” (Y page 102). The climate
control will then adjust the interior
temperature to the set value much faster.
Deactivating the climate control
system
GWarning!
When the climate control system is switched
off, the outside air supply and circulation are
also switched off. Only choose this setting for
a short time. Otherwise the windows could fog

addition, the air conditioning dehumidifies
the interior air and helps prevent window

The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.
! If the air conditioning cannot be activated
again, this indicates that the air
conditioning is losing refrigerant. The
compressor has turned off.
Have the air conditioning checked at the
nearest authorized Mercedes-Benz Center.
Automatic mode
When operating the climate control system in
automatic mode, the interior air temperature,
air volume and air distribution are adjusted
automatically.
In automatic mode, cooling with
dehumidification is switched on. This function
can be switched off if necessary.GWarning!

Notes on 3-zone automatic climate
control
With the help of a sun sensor, the automatic
climate control determines the relation of the
sun to the vehicle and automatically adjusts
the inside temperature for every individual
zone.
The automatic climate control is operational
whenever the engine is running. It cools the
vehicle’s interior according to the angle and
intensity of the sun’s rays, the outside
temperature and the selected temperature.
You can operate the automatic climate
control in either the automatic or manual
mode.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.
GWarning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
