114Climate controlAir conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has controls for:
n=cooling4=air recirculation
Cooling n
Operated with the n button and is
functional only when the engine and
fan are running.
The air conditioning system cools and dehumidifies (dries) as soon as the
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. Activated cooling
might inhibit Autostops.
Air recirculation system 4
Operated with the 4 button.9Warning
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.
Air distribution to l: Air recirculation
is deactivated.
Maximum cooling Briefly open the windows so that hot
air can disperse quickly.
■ Cooling n on.
■ Air recirculation system 4 on.
■ Press air distribution switch M.
■ Set temperature control to coldest level.
■ Set fan speed to highest level.
■ Open all vents.
Demisting and defrosting the
windows V
■ Press button V: fan automatically
switches to higher speed, the air distribution is directed towards the
windscreen.
■ Set temperature control to warmest

be inhibited until the V button is
pressed again.
If the l button with activated fan is
pressed while the engine is running,
an Autostop will be inhibited until the
l button is pressed again or until
the fan is deactivated.
If the V button is pressed while the

AUTO=automatic mode4=manual air recirculationV=demisting and defrosting
Heated rear window Ü 3 30.
The preselected temperature is
automatically regulated. In the
automatic mode, the fan speed and
air distribution automatically regulate
the air flow.
The system can be manually adapted via the use of air distribution and air
flow controls.
Each change of settings is shown in
the Info-Display for a few seconds.
The electronic climate control system
is only fully operational when the
engine is running.

Automatic mode AUTO
Basic setting for maximum comfort:■ Press AUTO button, the air
distribution and fan speed are
regulated automatically.
■ Open all air vents.
■ Press n to switch on cooling.
■ Set the desired temperature.
Temperature preselection Temperatures can be set to the
desired value.
If the minimum temperature is set, the
climate control system runs at
maximum cooling.
If the maximum temperature is set, the climate control system runs at maximum heating.
Notice
If the temperature will be reduced for
climate comfort reasons, an
Autostop can be inhibited or the
engine will restart automatically,
when cooling is switched on.
Stop-start system 3 122.
The temperature can be adjusted separately for driver and front
passenger side.
Demisting and defrosting the
windows V
■ Press button V.
■ Temperature and air distribution are set automatically and the fan
runs at high speed.
■ Switch on heated rear window Ü.
■ To return to previous mode: press button V, to return to automatic
mode: press button AUTO.Notice
If the V button is pressed while the
engine is running, an Autostop will
be inhibited until the V button is
pressed again.
If the l button with activated fan is
pressed while the engine is running,
an Autostop will be inhibited until the
l button is pressed again or until
the fan is deactivated.
If the V button is pressed while the
engine is in an Autostop, the engine will restart automatically.
If the l button is pressed with
activated fan while the engine is in an Autostop, the engine will restart
automatically.
Manual settings Climate 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
The selected fan speed is indicated
with x and a number in the display. If
the fan is switched off, the air
conditioning is also deactivated.

Combination of settings are possible.
Return to automatic air distribution:
Deactivate corresponding setting or
press button AUTO.
Cooling n
Activate or deactivate with the n
button.
The air conditioning system cools and dehumidifies (dries) when outsidetemperature 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. Activated cooling
may inhibit an Autostop.
The display will indicate Eco when
cooling is deactivated.
Air recirculation mode 4
Press button 4 once to activate the
manual air 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.
Air conditioning with the engine
not running
When ignition is off, the residual heat or cooling in the system can be used
for climate control in passenger
compartment.
Auxiliary heater Air heater
Quickheat is an electric auxiliary air
heater which automatically warms up the passenger compartment more
quickly.

118Climate controlAir 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 to the right. 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 to the left.
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.
Maintenance
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.

Control of the vehicleNever coast with engine not
running (except during Autostop)
Many systems will not function in this
situation (e.g. brake servo unit, power steering). Driving in this manner is a
danger to yourself and others. All
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 122.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.Steering
If power steering assist is lost
because the engine stops or due to a
system malfunction, the vehicle can
be steered but may require increased
effort.
Control indicator c 3 86.Caution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.

Driving and operating121Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and
engine oil consumption may be
higher and the cleaning process of the diesel particle filter may take
place more often. Autostop may be inhibited to allow for charging the
battery.
Diesel particle filter 3 125.Ignition switch positions0=Ignition off1=Steering wheel lock released,

Manual transmission: operate clutch.
Automatic transmission: operate
brake and move the selector lever to
P or N.
Do not operate the accelerator pedal. Diesel engine: turn the key to position2 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 3 and
release: an automatic procedure
operates the starter with a short delay
as long as the engine is running, see
Automatic Starter Control.
