Climate control1079Warning
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.
To return to Automatic mode: Press
AUTO button.
Rear heating system
The rear passenger compartment
heating fan assists air flow to the rear
passenger compartment via the rear
air vents.
The rate of air flow is determined by
the fan. Air temperature is controlled
using the temperature control on the
instrument panel.
Rear air conditioning system
The rear air conditioning system is
actuated in conjunction with the front
passenger compartment air
conditioning system.
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.
108Climate controlAuxiliary 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.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat, set the
air distribution to V and turn the fan
on.
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

9 Warning
When refuelling, switch off the
remote control unit as well as the
heater!
The remote control has a maximum
range of 1000 metres. The range may
be reduced due to environmental
conditions and as the battery
becomes weaker.
112Climate controlAir 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.9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Centre air vents
To open or close the centre air vents
and direct the flow of air, tilt the slats
up or down and turn the adjuster
wheel left or right.
Side air vents
To open or close the side air vents, tilt the slats up or down.
Direct the flow of air by rotating the
vents.
Depending upon the position of the
temperature control, air will be
directed into the vehicle via the side
air vents.
Rear air vents
Depending on vehicle, additional
adjustable air vents are located in the
rear passenger compartment.
Fixed air vents Additional air vents are located
beneath the windscreen and door
windows, in the foot wells and,
depending on vehicle, in the rear
passenger compartment.
Glovebox cooler
The air conditioning system can also
keep the contents of the glovebox
cool.
116Driving and operatingStarting 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.

Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emissions. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It restarts the engine
automatically as soon as the clutch
pedal is depressed.
A vehicle battery sensor ensures that
an Autostop is only performed if the
vehicle battery is sufficiently charged
for a restart.
Driving and operating121Conditions for an Autostop
