General notes
In automatic mode, the set temperature is main-
tained at aconstant level. The system automat-
ically regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode works best when cooling with
air dehumidification is also activated. If neces-
sary, cooling with air dehumidification can be
deactivated.

Air vents
Important safety notes
GWARNING
Very hot or very cold air can flow from the air
vents. This could result in burns or frostbitei n
the immediate vicinity of the air vents. There
is ar isk of injury.
Make sure that all vehicle occupants always
maintain asufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
In order to ensure the direct flow of fresh air
through the air ventsi nto the vehicle interior,
please observe the following notes:
Rkeep the air inlet between the windshield and
the hood free of blockages, such as ice, snow or leaves.
Rnever cover the air ventsora ir intake grilles in
the vehicle interior.
iFor virtually draft-free ventilation, adjust the
sliders of the air ventstot he center position.

erwise, water may enter the vehicle interior or
the engine compartment.This can damage
the electronic component sinthe engine or
the automatic transmission. Water can also
be drawn in by the engine' sair suction nozzles
and this can cause engine damage.
If you have to drive on stretches of road on which
water has collected, please bear in mind that:
Rin the case of standin gwater, the water level
must be no higher than the lower edge of the
vehicle body
Ryou should drive no faster than walking pace
Off-road fording
!Under no circumstances should you accel-
erate before entering the water. The bow
wave could cause water to enter and damage
the engine and other assemblies.
!Do not open any of the vehicle's doors while
fording. Otherwise, water could get into the
vehicle interior and damage the vehicle's
electronics and interior equipment.
iYou may only drive through fresh water.
RObserve the safety notes (Ypage 127) and
general notes (Ypage 127) on driving off-
road.
REstablish how deep the water is and the char-
acteristics of the body of water before ford-
ing.
RSwitc hoff automatic climate control
RShift the transfer case to the off-road driving
position LOW RANGE (Ypage 145).
REngage the differential locks if necessary
(Ypage 148).
RAvoid high engine speeds.
REnter and exit the water at aflat place and at
as teady walking pace.
RDrive slowly and at an even speed through the
water.
REnsure that abow wave does not form as you
drive.
RDo not stop and do not switch off the engine.
Water offers ahigh degree of resistance, and
the ground is slippery and in some cases
unstable. Therefore, it is difficult and danger-
ous to pull away in water.
RClean any mud from the tire tread after ford-
ing.
RApply the brakes to dry them after fording. Always observe the fordingd
epth values
(
Ypage 283).
Winter driving
GWARNING
If you shift down on aslippery road surface in
an attempt to increase the engine' sbraking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on aslippery road surface.
GWARNING
If you select the LOW RANGE off-road gear on
as lippery road surface, the wheels could lose
traction:
Rif you remove your foot from the accelera-
tor pedal when driving
Rif off road ABS intervenes when braking
If the wheels lose traction .the vehicle can no
longer be steered. There is an increased dan-
ger of skidding and accidents.
Never select the LOW RANGE off-road gear
when driving on slippery road surfaces.
Have your vehicle winter-proofed at aqualified
specialist workshop at the onset of winter.
Drive particularly carefully on slippery road sur-
faces. Avoid sudden acceleration, steerin gand
braking maneuvers. Do not use cruise control or DISTRONIC PLUS.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the automatic transmission to position
N .
The outside temperature indicator is not
designed to serve as an ice-warning device and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after ashort delay.
Indicated temperatures just above the freezing
point do not guarantee that the road surface is
free of ice. The road may still be icy, especially in
wooded areas or on bridges. The vehicle could
skid if you fail to adapt your driving style. Always
