Climate control115Air 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.

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.
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
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.

Driving and operating123
Deactivation
Deactivate the stop-start system
manually by pressing the eco button.
Deactivation is indicated when the
LED in the button extinguishes.
Autostop
If the vehicle is at a low speed or at a standstill, activate an Autostop as
follows:
■ Depress the clutch pedal
■ set the lever in neutral
■ release the clutch pedal
The engine will be switched off while
the ignition stays on.
An Autostop is indicated by the
needle at the AUTOSTOP position in
the tachometer.
During an Autostop, the heating
performance, power steering and
brake performance will be
maintained.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled:
■ The stop-start system is not manually deactivated
■ the bonnet is fully closed
■ the driver's door is closed or the driver's seat belt is fastened
■ the battery is sufficiently chargedand in good condition
■ the engine is warmed up
■ the engine coolant temperature is not too high
■ the engine exhaust temperature is not too high, e.g. after driving with
high engine load
■ the ambient temperature is not too low
■ the climate control system allows an Autostop
■ the brake vacuum is sufficient
■ the self-cleaning function of the diesel particle filter is not active
■ the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
Ambient temperature near to the
freezing point can inhibit an Autostop.
Certain settings of the climate control
system may inhibit an Autostop. See
Climate control chapter for more
details.
124Driving and operating
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 121.
Battery discharge protection
To ensure reliable engine restarts, several battery discharge protection
features are implemented as part of
the stop-start system.
Power saving measures
During an Autostop, several electrical
features such as auxiliary electric
heater or rear window heating are
disabled or switched into a power
saving mode. The fan speed of the
climate control system is reduced to
save power.
Restart of the engine by the
driver Depress the clutch pedal to restart the
engine.
The engine start is indicated by the
needle at the idle speed position in
the tachometer.If the selector lever is shifted out of
neutral before depressing the clutch
first, control indicator - illuminates
or is shown as a message in the Driver Information Centre.
Control indicator - 3 84.
Restart of the engine by the
stop-start system
The selector lever has to be in neutral to enable an automatic restart.
If one of the following conditions occurs during an Autostop, the
engine will be restarted automatically
by the stop-start system:
■ The stop-start system is manually deactivated
■ the bonnet is opened
■ the driver's seat belt is unfastened and the driver's door is opened
■ the engine temperature is too low
■ the battery is discharged
■ the brake vacuum is not sufficient
■ the vehicle starts to move■ the climate control system requests
an engine start
■ the air conditioning is manually switched on
If the bonnet is not fully closed, a
warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during engine restart might be
noticeable.
Parking ■ Do not park the vehicle on an easily
ignitable surface. The high
temperature of the exhaust system
could ignite the surface.
■ Always apply parking brake without
pressing release button. Apply as
firmly as possible on downhill or
uphill slopes. Depress the foot
brake at the same time to reduce
operating force.
■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock engages.
130Driving and operatingManual transmission
To engage reverse, with the vehicle
stationary wait 3 seconds after
depressing the clutch pedal and then press the release button on the
selector lever and engage the gear.
If the gear does not engage, set the
lever to neutral, release the clutch
pedal and depress again; then repeat
gear selection.
Do not slip the clutch unnecessarily.
When operating, depress the clutch
pedal completely. Do not use the
pedal as a foot rest.
Caution
It is not advisable to drive with the hand resting on the selector lever.
Drive systems
All-wheel drive
The All-Wheel Drive (AWD) system
enhances driving characteristics and
stability, and helps to achieve the best possible driveability regardless of
ground surface. The system is always
active and cannot be deactivated.
The torque is distributed steplessly
between the wheels of the front and rear axle, depending on the driving
conditions. Additionally the torque
between the rear wheels is distributed
depending on the surface.
For optimum system performance,
the vehicle's tyres should not have
varying degrees of wear.
When using a temporary spare
wheel, the AWD system is
automatically disabled.
The AWD system will also be
temporarily disabled to protect the
system from overheating if there is
excessive wheel spin. When the
system cools down, AWD will be
restored.
