function is activated and the engine is running, the system switches
between daytime running lights and headlights depending on the external lighting conditions.
For reasons of safety, it is advisable
to have the automatic light control

Air conditioning system
Additional to the heating and
ventilation system, the air
conditioning system has:
AC=cooling4=air recirculationCooling (AC)
Operated with the AC button and
functional only when the engine and
fan are running. LED illuminates in
the button when activated.
The air conditioning system cools and
dehumidifies (dries) the air 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.
Notice
Air conditioning performance is
reduced when ECO mode has been
activated 3 108.
Air recirculation system 4
Operated with the 4 button. LED
illuminates in the button when
activated.9 Warning
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 from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen might mist up from outside when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and avoid the use
of air distribution settings J and V.
Maximum cooling
Briefly open the windows so that hot
air can disperse quickly.
■ Cooling AC on.
■ Air recirculation system 4 on.
■ Set air distribution control to M.

The preselected temperature is
automatically regulated. In Automatic mode, the fan speed and air

The system can be manually adapted via the use of air distribution and air
flow controls.
Electronic climate control system is only fully operational when the engine is running.

■ Switch on the fan.
■ Press AUTO button; fan speed, air
distribution, cooling and air

automatically.
■ Set the desired temperature.
■ Open all air vents.

102Climate control
Rear air conditioning fan switch
The rear air conditioning fan assists
air flow to the rear passenger
compartment via the rear air vents.
Switch on the fan while the air
conditioning system is operating to
allow cooled and dehumidified (dried) air to be distributed.
The rate of air flow is determined by
the fan.
Auxiliary heater
Coolant heater The Eberspächer engine-
independent, fuel-powered coolant
heater provides rapid heating of the
engine coolant to enable heating of
the vehicle interior without the engine
running.Caution
Do not touch the exhaust pipe. It
may be hot even after the engine
has been switched off, due to
coolant heater operation.
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat and the
air distribution to V.
9Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.
Control units The timer or remote control unit turns
the system on and off, and is used to
programme specific departure times.

Climate control107Maintenance
Air intake
The air intake 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 is
recommended that the climate control system be checked annually, 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

Driving economically ECO mode
ECO mode is a function that
optimises fuel consumption. It affects engine power, heating, air
conditioning and electrical
consumers.
Activation
Press the ECO button. Control
indicator ECO illuminates in the
instrument cluster when activated.
During driving, it is possible to
temporarily disable ECO mode, e.g.
to increase engine performance, by
depressing the accelerator pedal
firmly. ECO flashes in the instrument
cluster.
ECO mode is reactivated when
pressure is reduced on the
accelerator pedal. ECO stops
flashing and illuminates continuously.
Deactivation
Press the ECO button again. Control
indicator ECO extinguishes in the
instrument cluster.
Control of the vehicle Never 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.

Driving and operating109
PedalsTo ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals.
Steering
If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
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.
During the running-in period fuel and
engine oil consumption may be
higher and the cleaning process of the diesel particle filter may take
place more often.
