automatically if the airbags deploy.
Turn and lane-change
signalsLever up=right turn signalLever down=left turn signal
The lever always springs back to its
original position.
If the lever is moved past the
resistance point, the turn signal is
switched on constantly. When the
steering wheel moves back, the turn
signal is automatically deactivated.
For three flashes, e.g. when changing lanes, press the lever until resistance
is felt and then release. This function
can be activated or deactivated
depending on the key used 3 95.
Move the lever to the resistance point
and hold for longer indication.
Switch the turn signal off manually by moving the lever slightly.
Acoustic turn signal The volume of the acoustic turn signal
can be adjusted. This function can be programmed depending on the key
used 3 95.

Air recirculation system 4
The air recirculation mode is 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.
In warm and very humid ambient air conditions, the windscreen might mist up from outside, when cold air is
directed to it. If windscreen mists up
from outside, activate windscreen
wiper and deactivate s.
Maximum cooling
Briefly open the windows so that hot air can disperse quickly.
■ Cooling n on.
■ Air circulation system 4 on.
■ Set temperature control to coldest level.
■ Set fan speed to highest level.
■ Set air distribution control to M.
■ Open all vents.
Demisting and defrosting the
windows
■ Cooling n on.
■ Set temperature control to warmest
level.
■ Set fan speed to highest level.
■ Set air distribution control to l.
■ Switch on heated rear window Ü.
■ Open side air vents as required and
direct them towards the door
windows.
Notice
If the settings for demisting and
defrosting are selected, an Autostop will be inhibited.
If the settings for demisting and
defrosting are selected while the
engine is in an Autostop, the engine will restart automatically.

Auxiliary heater Air heater
Quickheat is an electric auxiliary air
heater which automatically warms up
the passenger compartment more
quickly.
Coolant heater
Diesel-engined vehicles have a fuel-
powered auxiliary heater.Air vents
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.
Set the direction of the air flow by
turning the adjuster wheel from right to left and raise or lower the horizontal slats.
Page 115 of 231

Climate control113
To close the vent, turn the adjuster
wheel to left or right to its stop.
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.
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 outside
temperature is too low.
Service For optimal cooling performance, it isrecommended 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

118Driving and operating
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.
Control indicator - 3 81.
Restart of the engine by the
stop-start system
The selector lever has to be in N 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 defrosting function is activated■ 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 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.■ If the vehicle is on a level surface or
uphill slope, engage first gear or set the selector lever to P before
switching off the ignition. On an
uphill slope, turn the front wheels
away from the kerb.
If the vehicle is on a downhill slope, engage reverse gear or set theselector lever to P before switching
off the ignition. Turn the front
wheels towards the kerb.
■ Lock the vehicle and activate the anti-theft locking system and the
anti-theft alarm system.

Driving and operating129
ABS starts to regulate brake pressureas soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent though
a pulse in the brake pedal and the
noise of the regulation process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off the system performs a self-test which may be audible.
Control indicator u 3 82.
Adaptive brake light
During full braking, all three brake
lamps flash for the duration of ABS
control.Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Always apply parking brake firmly
without operating the release button,
and apply as firmly as possible on a
downhill or uphill slope.
To release the parking brake, pull the lever up slightly, press the release
button and fully lower the lever.
To reduce the operating forces of the
parking brake, depress the foot brake
at the same time.
Control indicator R 3 81.

130Driving and operatingBrake assistIf the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as
soon as the vehicle begins to
accelerate.
The hill start assist is not active during
an Autostop.Ride control systems
Electronic stability
program
Electronic stability program
(ESP® Plus
) improves driving stability
when necessary, regardless of the type of road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESP® Plus
is operational as soon as
control indicator v extinguishes.
