The automatic central locking function can
be switched off ( Y page 144).
Automatic transmissionGWarning!
It is dangerous to shift the automatic
transmission out of park position P or neutral
position N if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and when your right
foot is firmly on the brake pedal.
! Only shift the automatic transmission into
reverse gear R or park position P when the
vehicle is stopped. Otherwise the
automatic transmission could be damaged.
XDepress the brake pedal.
The gear selector lever can now be used.XShift the automatic transmission into drive
position D or reverse gear R.
i
Shifting the automatic transmission out of
park position P is only possible with the
brake pedal depressed.
Without the brake pedal depressed, the
gear selector lever can be moved up or
down. However, the parking pawl remains
engaged, not allowing shifting to occur.
XWait for the gear selection process to
complete before setting the vehicle in
motion.XIf engaged, release the parking brake.XRelease the brake pedal.XCarefully depress the accelerator pedal.
After a cold start, the automatic transmission
shifts at a higher engine speed. This allows
the catalytic converter (gasoline engine) or
the oxidation catalyst (diesel engine) to reach
its operating temperature earlier.
For more information on driving, see “Driving
instructions” ( Y page 254).
Problems while driving
The engine runs erratically and misfires
R Gasoline engine: An ignition cable may be
damaged.
R The engine electronics may not be
operating properly.
R Gasoline engine: Unburned gasoline may
have entered the catalytic converter and
damaged it.
XGive very little gas.XHave the problem checked at an authorized
Mercedes-Benz Center as soon as possible.
The coolant temperature is above
248‡ (120†)
The coolant is too hot and is no longer cooling
the engine.
XStop the vehicle in a safe location as soon
as possible.XTurn off the engine immediately.XAllow the engine and coolant to cool off.XCheck the coolant level and add coolant if
necessary ( Y page 226).
In case of accident
If the vehicle is leaking fuel:
XDo not start the engine under any
circumstances.XExit the vehicle at a safe distance from the
roadway.XNotify local fire and/or police authorities.
If the extent of the damage cannot be
determined:
XContact an authorized Mercedes-Benz
Center or call Roadside Assistance.112Driving and parkingControls in detail

Climate control system
Overview of climate control system functions
Your vehicle is equipped with either of the following climate control systems:
Dual-zone automatic climate control
USA only
Canada only
3-zone automatic climate control
Canada only
The dual-zone automatic climate control
combines an automatic heating and
ventilation system with a cooling system.
You can adjust the dual-zone 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.
Rear climate control
Canada only
The rear climate control allows separate climate settings for the rear compartment.180Climate control systemControls in detail

It can only function optimally when you are
driving with the windows, the tilt/sliding
sunroof or tilt/sliding panel closed.
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 ( Y page 185) is
deactivated.
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.
XKeep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing objects on
the air flow-through exhaust slots below the
rear window.
i If the vehicle interior is hot, ventilate the
interior before driving off, see “Summer
opening feature” (Y page 107). The climate
control will then adjust the interior
temperature to the set value much faster.
Deactivating the climate control
systemGWarning!
When the climate control system is
deactivated, the outside air supply and
circulation are also deactivated. Only choose
this setting for a short time. Otherwise the
windows could fog up, impairing visibility and
endangering you and others.

or
XPress button Ã.
The indicator lamp above the button comes
on. Air volume and air distribution are
adjusted automatically.
Air conditioning
The air conditioning is operational while the
engine is running and cools the interior air to
the temperature set by the operator. In
addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging.
GWarning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
i Condensated water may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.

The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.
Deactivating
It is possible to deactivate the air
conditioning. The interior air will then no
longer be cooled or dehumidified.

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!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.

Ventilated glove box
The glove box can be ventilated, for instance
to cool its contents, when the climate control
system is activated. The level of airflow to the
glove box depends on the airflow and air
distribution settings. The temperature of the
air is approximately the same as that of the
air flowing from the center air vents.
! Close the glove box air vent when heating
the vehicle interior. Activate the air
conditioning (cooling function) when the
outside temperature is high. Otherwise,
temperature-sensitive items stored in the
glove box could be damaged.
