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
level.
■ Switch on heated rear window Ü.
■ Open side air vents as required and
direct them towards the door
windows.

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.
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 85.
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.
Parking9 Warning
■ Do not park the vehicle on an
easily ignitable surface. The
high temperature of the exhaust system could ignite the surface.
■ Always apply the parking brake.
Activate the parking brake
without pressing the release
button. Apply as firmly as
possible on a downhill slope or
134Driving and operating9Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Control indicator b 3 87.
Deactivation
TC can be switched off when spinning of drive wheels is required:
press button t briefly to deactivate
TC, k illuminates. Deactivation is
displayed as status message in the
Driver Information Centre.
TC is reactivated by pressing the t
button again.
TC is also reactivated the next time
the ignition is switched on.
Electronic Stability Control Electronic Stability Control (ESC)
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.
ESC is operational after each engine
start as soon as the control indicator b extinguishes.
When ESC operates b flashes.9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.

Forward collision alert
The forward collision alert can help to
avoid or reduce the damage caused
by front-end crashes. If a vehicle
directly ahead is approached too
quickly, a warning chime and alert in
the Driver Information Centre is
provided.
Driving and operating139
The green illuminated vehicle ahead
symbol A appears in the
speedometer when the system has
detected a vehicle in the driving path. A precondition is that forward collision
alert is activated in the vehicle
personalisation menu 3 100 or that it
is not deactivated with button V
(depending on the system, see
following).
Forward collision alert based on front camera system
Forward collision alert uses the front
camera system in the windscreen to
detect a vehicle directly ahead, in
your path, within a distance of approx.
60 metres.
Activation
Forward collision alert operates
automatically above 25 mph, if it is not deactivated with button V, see
below.
Selecting the alert sensitivity
The alert sensitivity can be set to
near, medium or far.
Press button V: the current setting is
shown on the Driver Information
Centre. Press button V again to
change the alert sensitivity.
Alerting the driver
When approaching another vehicle
too rapidly, the collision alert warning page will be indicated in the Driver
Information Centre. Simultaneously a
warning chime sounds. Depress the
brake pedal, if it is required by the situation.
Deactivation
The system can be deactivated.
