The air conditioning system cools and
dehumidifies (dries) when outside
temperature is above a specific level. Therefore condensation may form
and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel.
Air recirculation system 4
The air recirculation mode is operated
with the 4 button.9Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the vehicle occupants to feel drowsy.
Maximum cooling
Briefly open the windows so that the heated air can disappear quickly.
■ Cooling n on.
■ Set air distribution control to M.
■ Set temperature control to required
temperature value.
■ Set fan control to A.
■ Open all vents.
The automatic climate control
automatically cools to the specified
value with the maximum cooling
power.
With the temperature control turned
to its minimum setting, the system
continually runs at maximum cooling. The system is automatically set to air
recirculation when the air conditioning
is on.

130Climate control
Air conditioning with the engine
not running When ignition is off, the residual heat
or cooling in the system can be used
for climate control in passenger
compartment.
Press the AUTO button with the
ignition off. Residual air conditioning
on will appear briefly in the display.
Residual climate control can only
operate for a limited period of time. To
cancel, press the AUTO button.
Auxiliary heater
Air heater Quickheat is an electric auxiliary air
heater which warms up the
passenger compartment more
quickly.
Coolant heater Diesel-engined vehicles have a fuel-
powered auxiliary heater.Air vents
Adjustable air vents
At least one air vent must be open
while cooling is on in order to prevent
the evaporator from icing up due to lack of air movement.
To open vent, turn the adjuster wheel
to B.
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster
wheel to 7.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door windows and in the foot wells.

Climate control131Maintenance
Air intake
The air intakes in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.
Air conditioning regular
operation In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when outside
temperature is too low.
Service For optimal cooling performance, it isrecommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
■ Functionality and pressure test■ Heating functionality
■ Leakage check
■ Check of drive belts
■ Cleaning of condenser and evaporator drainage
■ Performance check

Control of the vehicleNever coast with engine not
running
Many systems will not function in this
situation (e.g. brake servo unit, power
steering). Driving in this manner is a
danger to yourself and others.
Pedals To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
Fuel and engine oil consumption may be higher during the running-in
period.

Starting engine with ignition
switch
Operate clutch and brake, automatic
transmission in P or N, do not
accelerate; for diesel engines, turn
the key to position 2 for preheating
until control indicator ! goes out;
turn key briefly to position 3 and
release key when engine is running.
Before restarting or to switch off the
engine, turn key back to position 0.
Starting engine with the
Start/Stop button
The electronic key must be inside the
vehicle. Operate clutch and brake,
automatic transmission in P or N, do
not accelerate, for diesel engines,
press the button briefly to start
preheating, move the steering wheel
slightly to release the steering wheel
lock, wait until control indicator !
goes out and then press button for
1 second and release when the
engine is running.

134Driving and operating
To repeat the starting procedure or to
switch off the engine, press the button again.
Starting the vehicle at low
temperatures
The start of the engine without
additional heaters is possible down to -25 °С for diesel engines and -30 °C
for petrol engines. Required is an engine oil with the correct viscosity,
the correct fuel, performed services
and a sufficiently charged battery.
With temperatures below -30 °C the
automatic transmission and the
manual transmission automated
need a warming phase of approx. 5
minutes. The selector lever must be
in position P respectively N.
Overrun cut-off The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator is released.Parking
■ Do not park the vehicle on an easily
ignitable surface. The high
temperature of the exhaust system
could ignite the surface.
■ Always apply parking brake without
pressing release button. Apply as
firmly as possible on downhill or
uphill slopes. Depress the foot
brake at the same time to reduce
operating force.
■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock engages.
■ If the vehicle is on a level surface or
uphill slope, engage first gear or set
the selector lever to P before
switching off the ignition. On an uphill slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill slope, engage reverse gear or set the
selector lever to P before switchingoff the ignition. Turn the front
wheels towards the kerb.
■ Lock the vehicle and activate the anti-theft locking system and the
anti-theft alarm system.
