Operational only in ignition switch
positions ACC or ON.
Control indicator in button.
Turn off as soon as vision is clear.
Rear window and exterior mirror heating is
switched off automatically after approx.
15 minutes.
To avoid discharging the battery, do not
operate when you are just starting the
vehicle, or if there is a build up of snow or
ice. Operate only with the engine running.
Do not use sharp instruments or abrasive
cleaners on rear window or exterior mirrors,
and avoid scratching or damaging their
heating elements.
Heated front seats 3
Operational only in ignition switch
positions ACC or ON.
Press switch ß on respective side one or
more times to set the desired heat output.
Control indicator in switch indicates which
of the three heating levels is active.
To switch heating off, set heat output to
the lowest level and press the switch again.
The control indicato r will extinguish.
Prolonged use could cause damage to
delicate and thin clothing and burn seat
occupants.
Avoid subjecting seats to heavy impacts,
as this may cause damage to the heating
element.
If temperature continues to rise, turn seat
heating off and consult a workshop.
Glove compartment cooling 3
Cooled air is fed into the glove
compartment through an air opening,
when the air conditioning is turned on.
Rotate adjustment wheel anti-clockwise to
allow the air conditioning to keep the
contents of the glove compartment cool.
Rotate adjustment wheel clockwise to close
air opening when glove compartment
cooling is not required.

Ventilation
zTurn air recirculation mode 4 off.
z For maximum ventilation to head area:
set air distribution rotary knob to M.
z For ventilation to footwell:
set air distribution rotary knob to K.
z For simultaneous ventilation to head
area and footwell:
set air distribution rotary knob to L.
z Turn temperature rotary knob to blue
area for cooling.
z Set fan to desired speed.
z Open adjustable centre and side air
vents. Heating
The amount of heat is dependent on the
engine temperature and is thus not fully
attained until the engine is warm.
For rapid warming of the passenger’s
compartment:
z
Activate air recirculation mode 4.
z Set the air distribution rotary knob to
K or L .
z Turn temperature ro tary knob to red
area for warm air.
z Set fan to 4 .
z Open adjustable side air vents.
Do not use this setting for extended
periods, as gradual deterioration in air
quality and an increase in humidity may
cause windows to mist up. To obtain a temperat
ure for a "cool head
and warm feet" effect:
z Turn air recirculation mode 4 off.
z Set the air distribution rotary knob to L.
z Turn temperature rotary knob to the
middle.
z Set fan to desired speed.
z Open adjustable centre and side air
vents.
The comfort and general wellbeing of
vehicle occupants are to a large extent
dependent on a suitab le ventilation and
heating setting.

z Switch on fan. Window demisting and defrosting
To clear misted or icy
windows, e.g. due to
damp weather, damp clothing or low
outside temperatures:
z Set air distribution rotary knob to l.
z Turn temperature ro tary knob to red
area for warm air. z
Set fan to 4.
z Close centre air vents.
z Open adjustable side air vents and direct
them towards door windows.
z Switch on heated rear window Ü.
For simultaneous warming of the footwell,
set air distribution rotary knob to J.
Air conditioning n and air recirculation
4 are turned on automatically to
improve defrosting efficiency when
position J or l is selected.
To prevent windows from misting up, do
not set air distribution rotary knob to
position J or l in extremely humid
weather when temperature rotary knob is
set to blue area for cooling.
9 Warning
Failure to follow thes e instructions could
lead to misted or icy windows and
accidents stemming from impaired
visibility.

Air recirculation mode
During ’normal’ operation, the heating,
ventilation and air co nditioning system
uses outside air. To prevent fumes or
unpleasant odours from entering the
vehicle when in stationary traffic and when
rapid heating or cooling of the passenger
compartment is required, press button 4;
control indicator in the button illuminates
and air is recirculated. Air recirculation mode should only be used
for brief periods, due to gradual
deterioration in air quality and an increase
in humidity, causing windows to mist up.
Driving with air recirculation mode on for
extended periods may cause vehicle
occupants to feel drowsy.
Press button
4 again to turn air
recirculation mode off; control indicator in
the button extinguishes and outside air is
drawn into the vehicle.
Air conditioning system
As a supplement to the heating and
ventilation system, the air conditioning
system cools and dehumidifies (dries)
inflowing air and removes dust and pollen,
to provide maximum comfort under any
weather conditions.
If cooling or dehumi dification is not
required, switch off cooling in order to save
fuel.

Cooling
Operational only with engine running and
with the fan switched on:
Control indicator in the button illuminates
when air conditioning is enabled and
extinguishes when the system is switched
off.
Cooling switches off automatically at low
outside temperatures.
Engine power and performance may be
affected when the system is on.
If the fan is switched off, the air
conditioning system will not operate. Once activated, the air conditioning
system is operated via the normal heating
and ventilation controls.
Even with air conditioning on, if
temperature rotary knob is set to warm, the
vehicle will still produce warm air in the
passenger compartment.
To improve efficiency of the air
conditioning, always close the windows,
to prevent chilled air from escaping.
Switching on the air conditioning will assist
in windscreen demisting. In very hot
temperatures, before starting the engine,
allow hot air to escape from the vehicle by
opening the windows and sun roof
3.
When the air conditioning system is
switched on, at least one of the adjustable
centre or side air vents must be open, so
that the evaporator does not ice up due to
lack of air movement.
Driving in stop-and-go traffic may reduce
the effectiveness of the air conditioning
system.
Using the air conditioning system when
driving up long hills or in heavy traffic
can cause engine overheating. If engine
coolant temperature warning control
indicator W illuminates in instrument
panel, turn off air co nditioning and allow
engine to idle for a few minutes (see
page 71). Normal cooling

Electronic Climate Control (ECC) 3
Provides the greatest amount of comfort in
the vehicle interior, regardless of the
weather, outside temperature or season.
To ensure a constant and comfortable
climate in the vehicle, the temperature of
the inflowing air, the air flow rate, air
distribution mode, air recirculation mode
and air conditioning are automatically
adapted based on the climate conditions
outside the vehicle and the current
temperature of the vehicle interior.
Temperature changes due to external
influences, such as direct sunlight, are
automatically compensated. When cooling (air conditioning
compressor) is active, air is cooled and
dehumidified.
The pollen filter removes dust, soot, pollen
and spores from the
inflowing outside air.

Automatic air recirculation
The automatic air recirculation system has
an air quality sensor to detect harmful
ambient gases, in which case it will switch
automatically to air recirculation mode.
Press automatic air recirculation button t;
the system provides the optimum settings
for almost all conditions. Control indicator
in the button illuminates when automatic
air recirculation is enabled.
Press button t again to turn automatic air
recirculation system off; control indicator in
the button extinguishes and outside air is
drawn into the vehicle.
The system is only operational when the
engine is running. Automatic mode
Basic setting for maximum comfort:
z
Press AUTO button.
z Open all air vents.
z Set temperature using central rotary
knob.
All air vents are actuated automatically in
automatic mode. The air vents should
therefore always be open - see page 104.
The control indicator in the AUTO button
illuminates when automatic mode has
been selected.
To switch the system off, set fan to x .Temperature preset
The central rotary knob can be used to set
the temperature; 22 °C, 24 °C and 26 °C
appear on the rotary
knob. Intermediate
settings are possible.
The selected temperature is maintained.
At the lowest or highest temperature
setting, the system works at maximum
cooling or heating.
