Unit of measurement To change the unit of measurement
for the duration of a journey:
With ignition off, simultaneously press
the power button 3 112 and press
and hold button on end of wiper lever; the Driver Information Centre flashes
for approx. 10 seconds until the new
unit is displayed. Release button on
end of wiper lever.

Interruption of power supply
If the power supply has been
interrupted or if the vehicle battery
voltage has dropped too low, the
values stored in the trip computer will be lost.Tachograph
The tachograph is operated as
described in the operating
instructions supplied. Observe
regulations regarding use.

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 3 110.
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 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.

■ Open all air vents.
To switch off the electronic climate
control system, switch off the fan.

104Climate 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 control109Maintenance
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
