Avoid driving at excessive engine speeds.
This may result in serious engine damage
that is not covered by the Mercedes-Benz
Limited Warranty.
Shift gear in a timely manner.
For more information on driving, see “Driving
instructions” ( Y page 221).
Automatic transmission G
Warning!
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.
X Depress the brake pedal.
The gear selector lever lock is released.
X Shift 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.
Only depressing the brake pedal releases
the gear selector lever lock.
X Wait for the gear selection process to
complete before setting the vehicle in
motion.
X If engaged, release the parking brake.
X Release the brake pedal.
X Carefully depress the accelerator pedal.
After a cold start, the automatic transmission
shifts at a higher engine speed. This allows the catalytic converter to reach its operating
temperature earlier.
For

more information on driving, see “Driving
instructions” ( Y page 221). Problems while driving
The
engine runs erratically and misfires R
An ignition cable may be damaged.
R The engine electronics may not be
operating properly.
R Unburned gasoline may have entered the
catalytic converter and damaged it.
X Give very little gas.
X Have 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.
X
Stop the vehicle in a safe location as soon
as possible.
X Turn off the engine immediately.
X Allow the engine and coolant to cool off.
X Check the coolant level and add coolant if
necessary ( Y page 196).
In case of accident If the vehicle is leaking fuel:
X
Do not start the engine under any
circumstances.
X Exit the vehicle at a safe distance from the
roadway.
X Notify local fire and/or police authorities.
If the extent of the damage cannot be
determined:
X Contact an authorized Mercedes-Benz
Center or call Roadside Assistance. 82

Climate control system
Overview of climate control system functions
Your vehicle is equipped with either of the following climate control systems: Climate control
(Y page 162) Automatic climate control
(Y page 163)The climate control combines a heating and
ventilation system with a cooling system. The automatic 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.

Notes on climate control system
The climate control system is operational
whenever the engine is running. You can
operate the climate control system in either
the automatic 9
or manual mode. The system
cools or heats the interior depending on the
selected interior temperature.
It can only function optimally when you are
driving with the windows and the retractable
hardtop closed.
Nearly

all dust particles, pollutants and odors
are filtered out before outside air enters the passenger compartment through the air
distribution system. G
Warning!
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 165) is
deactivated. G
Warning!
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.
X Keep the air intake grille in front of the
windshield free of snow and debris.
When the retractable hardtop is closed, 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. The climate
control will then adjust the interior
temperature to the set value much faster. Deactivating the climate control
system
G
Warning!
When the climate control system is
deactivated, the outside air supply and
circulation are also deactivated. Only choose
this setting for a short time when the

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. G
Warning!
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.

G
Warning!
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold

(depending on the set temperature). This
may cause burns or frostbite to unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
For best possible performance of the climate
control:
X Keep the air intake grille in front of the
windshield

free of snow, leaves, sticks, and
any other debris.
X Always keep all air vents and grilles in the
passenger compartment free from
obstruction.
