2009 MERCEDES-BENZ SLR window

194 Controls in detailAutomatic climate controlAir conditioning
The air conditioning (cooling) function is
operational when the engine is running and
cools the vehicle interior down to the se-
lected temperature. In addition, the cool-
ing function dehumidifies the air in the
vehicle interior, thus preventing the
windows from fogging up.Deactivating
It is possible to deactivate the cooling
function of the automatic climate control
system. The air in the vehicle will then no
longer be cooled or dehumidified.

Press ± button (
page 186).
The indicator lamp on the ±
button comes on. The cooling function
switches off after a short delay.Activating
Moist air can fog up the windows. You can
dehumidify the air with the air
conditioning.

Press ± button again (
page 186).
The indicator lamp on the ± button
goes out.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.
Warning!
G
If you turn off the cooling function, 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/or
others.i
Condensation may drip out from underneath
the vehicle. This is normal and not an indication
of a malfunction.
i
Under certain circumstances, e.g. when the
fuel system is too hot and needs to be cooled,
the cooling switches on again automatically. The
red lamp on the ± button the automatic
climate control panel flashes.
After cooling the fuel system sufficiently, the air
conditioning switches off again and the red lamp
stops flashing.
!
If you press the ± button on the auto-
matic climate control panel and it starts to flash,
this indicates that the air conditioning is losing
refrigerant. The compressor has turned off. The
air conditioning cannot be turned on again.
Have the air conditioning checked at the nearest
authorized Mercedes-Benz Center.

opened or closed completely and a door is
open.
Warning!
G
To prevent possible accidents, only drive the
vehicle with the soft top either completely
closed and locked, or fully lowered into its
storage compartment.
If the soft top does not open or close com-
pletely, the soft top hydraulic system is de-
pressurized and the soft top is lowered:

after approximately seven minutes
when the ignition is switched on


after approximately 15 seconds when
the ignition is switched off
Shortly before the soft top is lowered, a
warning will sound and the K symbol and
the message
Top Lowering
appear in the
multifunction display.
Lock the soft top again before driving any
further. Otherwise, the unlocked soft top
could open while the vehicle is in motion and
cause you to lose control of the vehicle. You
or others could be injured as a result.

sure that nobody is trapped or injured by the
moving parts such as the soft top linkage.
If potential danger exists, release the soft
top switch. The soft top folding mechanism
stops immediately.Warning!

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. A child’s
unsupervised access to a vehicle could
result in an accident and/or serious
personal injury.
!
The opened soft top is stored behind the
roll-over bars. Never sit on the stored soft top
and never store objects on it. You will otherwise
damage the soft top.
Never use the space that emerges between the
roll-over bars and the rear window when the soft
top is closed as a storing space.
!
When you open or close the soft top, make
sure


there is sufficient clearance, as the soft top
swings upwards


that the soft top fabric is not frozen


that the soft top is not dirty or wet


that no items are placed on the soft top
Otherwise the soft top or other vehicle compo-
nents could be damaged.
!
Please keep in mind that weather conditions
can sometimes change rapidly. Make sure to
close the soft top when leaving the vehicle. If
water enters the vehicle interior, vehicle elec-
tronics could be damaged which is not covered
by the Mercedes-Benz Limited Warranty.

Do not place heavy or fragile objects, or ob-
jects having sharp edges in the map pocket.
In an accident, during hard braking or sud-
den maneuvers, they could be thrown
around inside the vehicle, and cause injury
to vehicle occupants.i
Canada only: The compact guide is located
in the map pocket.
Warning!
G
To help avoid personal injury during a colli-
sion or sudden maneuver, exercise care
when storing objects in the vehicle. Put lug-
gage or cargo in the trunk. Do not pile lug-
gage or cargo higher than the seat backs.
Do not place anything on the shelf below the
rear window.
Parcel nets cannot secure hard or heavy
objects.
Keep compartment lids closed. This will help
to prevent stored objects from being thrown
about and injuring vehicle occupants during
an accident.

243 Operation
Driving instructions
Road salts and chemicals can adversely
affect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired braking
efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking
efficiency should be tested as soon as
possible after driving is resumed.
For more information, see “Winter driving”
(
page 292).
Standing water
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Warning!
G
If the vehicle becomes stuck in snow, make
sure snow is kept clear of the exhaust pipe
and from around the vehicle with the engine
running. Otherwise deadly carbon monoxide
(CO) gases may enter vehicle interior
resulting in unconsciousness and death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the
vehicle not facing the wind.Warning!
G
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the
road surface is free of ice.
!
Do not drive through flooded areas or water
of unknown depth. Before driving through water,
determine its depth. Never accelerate before
driving into water. The bow wave could force
water into the engine and auxiliary equipment,
thus damaging them.
If you must drive through standing water, drive
slowly to prevent water from entering the pas-
senger compartment or the engine compart-
ment. Water in these areas could cause damage
to electrical components or wiring of the engine
or transmission, or could result in water being in-
gested by the engine through the air intake caus-
ing severe internal engine damage. Any such
damage is not covered by the Mercedes-Benz
Limited Warranty.
