120Climate control9Warning
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 A/C on.
● Air recirculation system 4 on.
● Set air distribution control to M.
● Set temperature control to coldest level.
● Set fan speed to highest level.
● Open all air vents.
Demisting and defrosting the
windows
● Set temperature control to warmest level.
● Set fan speed to highest level.
● Set air distribution control to V.
● Switch cooling A/C on.
● Switch on heated rear window Ü.
● Open side air vents as required and direct them towards doorwindows.
● For simultaneous warming of the
foot well, set air distribution
control to J.

122Climate controlCooling A/C
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.
Note
Air conditioning performance is
reduced when ECO mode has been
activated 3 131.
If no cooling or drying is required
press A/C OFF to switch the cooling
system off, thus saving fuel. LED
illuminates in the button.
To return to Automatic mode: Press
AUTO button.
Air recirculation mode u
Activate or deactivate manual air recirculation mode with u. 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.
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.
Page 126 of 235

124Climate controlSet the fan < to regulate the amount
of cooled air to be flown into the rear
passenger compartment.
Auxiliary heater Coolant heater
The 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.

9 Warning
When refuelling, switch off the
remote control unit as well as the
heater!
The remote control has a maximum
range of 1000 m. The range may be
reduced due to environmental
conditions and as the battery
becomes weaker.

Teach remote control (Type B)
Up to four additional remote control
units may also be configured. During
additional teaching processes, the
oldest transmitter will be deleted each
time.
Remove the heater fuse for
5 seconds, then refit the fuse. Within
2–6 seconds press OFF for
1 second. Teaching is completed.
If the remote has not been used for a long period, press the OFF button six
times at intervals of 2 seconds, then
press and hold for another
2 seconds, then wait 2 minutes.
Manual control
Depending on version, the auxiliary
heater can also be switched on for the
last duration time or the default
duration 30 minutes, or cut-off
immediately, using the button on the
lower part of the instrument panel,
beside the steering wheel.
The LED in the button confirms
operation.
Battery replacement
Replace the battery when the range
of the remote control is reduced or when the battery charge symbol
flashes.

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

Depending upon the position of the
temperature control, air will be
directed into the vehicle via the side
air vents.
