If the minimum temperature Lo is set,
the climate control system runs at
maximum cooling, if cooling n is
switched on.
If the maximum temperature Hi is set,
the climate control system runs at
maximum heating.
Note
If n is switched on, reducing the set
cabin temperature can cause the
engine to restart from an Autostop or inhibit an Autostop.

Manual settingsClimate control system settings can
be changed by activating the buttons
and rotary knobs as follows.
Changing a setting will deactivate the Automatic mode.
Fan speed Z
Press lower button to decrease or
upper button to increase fan speed as
shown in the illustration. The fan
speed is indicated by the number of
segments in the display.
Pressing the lower button for longer:
fan and cooling are switched off.
Pressing the upper button for longer:
the fan runs at maximum speed.
To return to Automatic mode: Press
AUTO button.
Air distribution s, M , K
Press appropriate button for desired
adjustment. Activation is indicated by illumination of the LED in the button.
s=to windscreen and front door
windows (air conditioning is
activated in the background to
help preventing windows from
fogging)M=to head area via adjustable air ventsK=to foot well
All combinations are possible.
Return to Automatic air distribution:
press button AUTO.
Cooling n

130Climate control
Press button n to switch on cooling.
Activation is indicated by illumination
of the LED in the button. Cooling is
only functional when the engine is
running and climate control fan is switched on.
Press button n again to switch off
cooling.
The air conditioning system cools and
dehumidifies (dries) 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 off the cooling system for fuel
saving reasons. When the cooling
system is switched off, no engine restart will be requested by the
climate control system during an
Autostop. Exception: defrost system
is activated and outside temperature
above 0° C requests a restart.
The display will indicate ACON when
cooling is activated or ACOFF when
the cooling is deactivated.Activation or deactivation of cooling
operation after engine start can be
changed in the Settings menu in the
Info-Display. Vehicle personalisation

Air recirculation mode 4
Press button 4 to activate air
recirculation mode. Activation is
indicated by illumination of the LED in
the button.
Press button 4 again to deactivate
recirculation mode.
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 may mist
up from outside, when cold air is
directed towards it. If windscreen
mists up from outside, activate
windscreen wiper and deactivate s.
Basic settings Some settings can be changed in the Settings menu in the Info-Display.

Climate control131Auxiliary heater
Air heater Quickheat is an electric auxiliary airheater which automatically warms up
the passenger compartment more
quickly.Air vents
Adjustable air vents At least one air vent must be open
while the cooling is on.
To open the vent, turn the adjuster
wheel towards the bigger W symbol.
Adjust the air amount at the vent
outlet by turning the adjuster wheel.
Direct the flow of air by tilting and
swivelling the slats.
To close the vent, turn the adjuster
wheel towards the smaller W symbol.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door windows and in the foot wells.

132Climate controlMaintenance
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 the
outside temperature is too low.
Service
For optimal cooling performance, it is recommended to annually check the
climate control system, 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

applicable version), taking into
consideration the vehicle weight in running order, as specified by the
regulation.
The figures are provided only for the
purpose of comparison between
different vehicle variants and must
not be taken as a guarantee for the
actual fuel consumption of a
particular vehicle. Additional
equipment may result in slightly
higher results than the stated
consumption and CO 2 figures.
Furthermore, fuel consumption is dependent on personal driving style
as well as road and traffic conditions.Trailer hitch
General information
Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
The bulb outage detection function for
trailer brake light cannot detect a
partial bulb outage, e.g. in case of 4 x
5 Watt bulbs, the function only detects lamp outage when only a single
5 Watt lamp remains or none remain.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball
bar for towing. Always keep the
coupling ball bar in the vehicle.Driving characteristics and
towing tips
Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements.
For trailers with low driving stability
and caravan trailers with a permitted
gross vehicle weight of more than
1200 kg the use of a stabiliser is
strongly recommended when driving
above 80 km/h.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 239.

182Vehicle care
■ Open the bonnet, close all doorsand lock the vehicle.
■ Close the soft top.
■ Cover the soft top to reduce environment influences.
■ Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems are not functional, e.g. anti-theft alarm
system.
Putting back into operation When the vehicle is to be put back into
operation:
■ Connect the clamp to the negative terminal of the vehicle battery.
Activate the electronics of the
power windows.
■ Check tyre pressure.
■ Fill up the washer fluid reservoir.
■ Check the engine oil level.
■ Check the coolant level.
■ Fit the number plate if necessary.End-of-life vehicle
recovery
Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our website, where legally required. Only
entrust this work to an authorised
recycling centre.Vehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.

Vehicle care185Engine coolantThe coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be above the
filling line mark. Top up if the level is
low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Power steering fluidCaution
Extremely small amounts of
contamination can cause steering
system damage and cause it to not work properly. Do not allow
contaminates to contact the fluid
side of the reservoir cap/dipstick or
from entering the reservoir.
