Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside. This setting cuts off the
intake of outside air and recirculates the
air in the passenger compartment.Activating

Press button, (
page 173).
The indicator lamp on the button
comes on.
iThese settings should only be selected
for a short time.
Warning!
G
When the outside temperature is
below 41°F (5°C), only switch to air
recirculation mode for short periods to
prevent window fogging.
Window fogging may impair visibility and
endanger you and others.
iIf you keep button, pressed the
side windows and panorama roof with
power tilt/sliding panel* will close.Warning!
G
Never operate the side windows and the
panorama roof with power tilt/sliding pan-
el* if there is the possibility of anyone being
harmed by the closing procedure.
Vehicles without panorama roof with power
tilt/sliding panel*:
In the event that the procedure causes
potential danger, the opening and closing of
the side windows can be immediately halted
by pressing or pulling the respective window
switch.


184 Controls in detailAutomatic climate control*The automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing 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.
The air conditioning will not engage (no
cooling) if the modeAC
OFF
is activated or
modeA/C is deactivated (page 192).
iFeature availability is based on prelimi-
nary information at time of printing.
The automatic climate control may not
be available as optional equipment on
all models.
Warning
G
When operating the automatic climate
control, the air that enters the passenger
compartment through the air vents in the
footwell can be very hot or very cold
(depending on the set temperature). This
may cause burns or frostbite on unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the foot-
well air vents. If necessary change the air
flow using the air distribution controls to
direct the air away from the footwell air
vents (
page 186).
Warning!
G
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.iSevere conditions (e.g. strong air
pollution) may require replacement of
the filter before its scheduled interval.
A clogged filter will reduce the air
volume to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off, see
“Opening (Summer opening feature)”
(page 245).
Keep 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.

Maximum cooling MAXCOOL
If the left and right air distribution controls
as well as the airflow volume control are
set toU (
page 183) and there is a
high need for cooling, the display
“MAXCOOL” appears.
This provides the fastest possible cooling
of the vehicle interior (when side windows
and panorama roof with power tilt/sliding
panel* are closed).
iThese settings should only be selected
for a short time.

The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs
which are harmful to the ozone layer.Residual heat and ventilation
(available on automatic climate control
panel design A only)
With the engine switched off, it is possible
to continue to heat or ventilate the interior
for up to 30 minutes. This feature makes
use of the residual heat produced by the
engine.

The residual heat is automatically turned
off:


when the ignition is switched on


after about 30 minutes


if the battery voltage drops
!If the air conditioning cannot be turned
on again, this indicates that the air
conditioning is losing refrigerant. The
compressor has turned itself off.
Have the air conditioning checked at
the nearest authorized Mercedes-Benz
Center.
iHow long the system will provide
heating depends on

the coolant temperature


the temperature set by the operator
The blower will run at speed setting 1
regardless of the air distribution
control setting.

278 OperationDriving instructionsBrakesTo help prevent brake disk corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes.
If your brake system is normally only sub-
jected to moderate loads, you should occa-
sionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads.
If the parking brake is released and the
brake warning lamp in the instrument clus-
ter stays on, the brake fluid level in the res-
ervoir is too low.Brake pad wear or a leak in the system may
be the reason for low brake fluid in the res-
ervoir.
Have the brake system inspected by quali-
fied technicians immediately. Contact an
authorized Mercedes-Benz Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Install only brake pads and brake fluid
recommended by Mercedes-Benz.Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking
effect. Maintain a safe distance from vehi-
cles in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an
accident.
!Be very careful not to endanger other
road users when you apply the brakes.
Refer to the description of the Brake
Assist System (BAS), (
page 82).
Warning!
G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.
