2010 MERCEDES-BENZ GL engine

The vehicle is lowered to off-road level 2.
Once off-road level 2 is reached, you will see,
for example, the following message in the
multifunction display:
While driving, the vehicle is lowered
automatically as follows:
RAt vehicle speeds above 55 mph
(88 km/h) or if the vehicle speed stays
between 40 mph (64 km/h) and 55 mph
(88 km/h) for approximately 20 seconds,
the off-road level 2 setting is canceled and
the vehicle is lowered to the off-road
level 1.
You will see, for example, the following
message in the multifunction display:
RAt speeds above 60 mph (96 km/h) the off-
road level 1 setting is canceled and the
vehicle is lowered to the highway level.
You will see, for example, the following
message in the multifunction display:
RDepending on the ADS setting
(Y page 159), the vehicle will be lowered to
the highspeed level when traveling at
higher speeds. At speeds below 25 mph
(40 km/h) at the latest, it will be returned
to the highway level.
iThe setting is stored when you turn off the
engine.
Highway level
! Keep in mind that on rough or uneven
roads, adjusting the vehicle to a lower level
may cause the vehicle underbody to come
in contact with the road and result in
damage to the vehicle underbody. Always
make sure the vehicle has sufficient ground
clearance before adjusting it to a lower
level.
XStart the engine.
When one or more indicator lamps = are on:
XTurn outer adjustment ring : repeatedly
to position 4 until all lit indicator lamps

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

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 177).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 107). The climate
control will then adjust the interior
temperature to the set value much faster.
Deactivating the climate control

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

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 switch off 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 Condensation may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
Deactivating
It is possible to deactivate the air
conditioning. The interior air will then no
longer be cooled or dehumidified.

Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e. g. before driving through
a tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.GWarning!
Fogged windows impair visibility,
endangering you and others. If the windows
begin to fog on the inside, switching off the
air recirculation mode immediately should
clear interior window fogging. If interior
window fogging persists, make sure the air
conditioning is activated, or press button

i The air recirculation mode is activated
automatically at high outside
temperatures.
The indicator lamp in button d is not lit
when the air recirculation mode is switched

A quantity of outside air is added after
approximately 30 minutes.
If you have turned off the air conditioning
or the outside temperature is below 41‡
(5†), the air recirculation mode will not
switch on automatically.
XDeactivating: Press button d.

temperature is below approximately
41‡ (5†)
R after 5 minutes if the air conditioning and
air-drying are turned off
R after 30 minutes if the outside
temperature is above approximately
41‡ (5†)
Residual heat and ventilation
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.
i How long the system will provide heating
depends on the coolant temperature and
the battery voltage.
Regardless of the temperature and air
volume set on the climate control panel, an
interior temperature is aimed at by 72‡
(22† ) and the blower runs on low speed to
protect the vehicle battery.

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
