Manual anti-dazzle
To reduce dazzle, adjust the lever on the underside of the mirror housing.
Wide view mirror
Depending on vehicle, a large convex
mirror is located in the front
passenger sun visor which helps to
increase visibility and reduce blind
spots.

Windscreen stickers
Do not attach stickers, e.g. toll road
stickers or similar, on the windscreen
in the area of the interior mirror.
Otherwise the detection zone of the
sensor in the mirror housing could be restricted.
Manual windows The door windows can be opened or
closed with the window cranks.
Power windows9 Warning
Take care when operating the
power windows. Risk of injury,
particularly to children.
Keep a close watch on the
windows when closing them.

3. Move out of the flow of traffic as quickly as possible without
impeding other vehicles.
4. Switch off ignition.
9 Warning
When the engine is off,
considerably more force is needed
to brake and steer. During an
Autostop the brake servo unit will still be operational.
Do not remove key until vehicle isstationary, otherwise the steeringwheel lock could engage
unexpectedly.

Automatic headlight activation
During poor lighting conditions the
headlights are switched on.
High beam
To change between low and high
beam, pull lever until a click is felt.
High beam assist This feature allows high beam to
function as the main driving light at
night and when vehicle speed is
faster than approx. 28 mph.
It switches to low beam when:
● A sensor detects the lights of oncoming or preceding vehicles.
● It is foggy or snowy.
● Driving in urban areas.
If there are no restrictions detected, the system switches back to high
beam.
Activation
Turn the outer light switch to AUTO
then push the turn signal lever
forwards to activate high beam assist.
The control indicator í illuminates
continuously in the instrument cluster when the assist is activated, while the
blue control indicator 7 3 91
illuminates when high beam is on.
Control indicator í 3 91.
Notice
Use of the system does not relieve
the driver from full responsibility for
vehicle operation.
Deactivation
Push the turn signal lever forwards
again. Control indicator í
extinguishes.
High beam assist is also deactivated when the outer light switch is moved
out of the AUTO position.
Notice
Depending on version, the system
can be also be deactivated via the
Infotainment system. Refer to
Infotainment system manual for
further information.

● Switch cooling A/C on.
● Set temperature control to warmest level.
● Set fan speed to highest level.
● Set air distribution control to V.
● Switch on heated rear window Ü.
● Open side air vents as required and direct them towards doorwindows.
● For simultaneous warming of the
foot well, set air distribution
control to J.
Notice
If V is pressed while the engine is
running, an Autostop will be inhibited
until V is pressed again.
If V is pressed while the engine is
in an Autostop, the engine will restart
automatically.

The system can be manually adapted by use of air distribution and air flow
controls.
The electronic climate control system
is only fully operational when the
engine is running.
For correct operation do not cover the
sensor on the instrument panel.

122Driving and operatingTo increase or decrease the fast idle
speed rate, consult a workshop.
Notice
When the fast idle function is
activated, the stop-start system is
automatically deactivated.
Stop-start system 3 122.
Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator is released.
Stop-start system The stop-start system helps to save
fuel and to reduce the exhaust
emission. When conditions allow, it
switches off the engine as soon as the
vehicle is at a low speed or at a
standstill, e.g. at a traffic light or in a
traffic jam. It starts the engine
automatically as soon as the clutch is
depressed. A vehicle battery sensor
ensures that an Autostop is only performed if the vehicle battery is
sufficiently charged for a restart.Activation
The stop-start system is available as soon as the engine is started, the
vehicle starts-off and the conditions
as stated below in this section are
fulfilled.
Deactivation
Deactivate the stop-start system
manually by pressing Î.
Deactivation is indicated when the
LED in the button illuminates.
Notice
When the fast idle function is
activated, the stop-start system is
automatically deactivated and
cannot be reactivated by pressing
Î . LED in button illuminates to
indicate deactivation and a
corresponding message may
appear in the Driver Information
Centre (DIC) 3 92.
Idle speed control 3 121.
Autostop
If the vehicle is at low speed or
standstill, activate an Autostop as
follows:
● depress the clutch pedal
● shift the selector lever to neutral (manual transmission) or N
(manual transmission
automated)
● release the clutch pedal
The engine will be switched off while
the ignition stays on if the required conditions are met.

146Driving and operatingParking assist
The parking assist makes reverse
parking easier by measuring the
distance between the rear of the
vehicle and obstacles. It is the driver,
however, who bears full responsibility for the parking manoeuvre.
The system consists of four ultrasonicparking sensors in the rear bumper.
Notice
Attached parts in the detection area
cause system malfunction.
Activation
When reverse gear is engaged, the
system switches itself on
automatically. Readiness for
operation is indicated by a brief
acoustic alarm.
An obstacle is indicated by buzzers.
The interval between the buzzers
becomes shorter as the vehicle gets
closer to the obstacle. When the
distance is less than 30 cm, the buzzer is continuous.9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the sensor can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
vans). Object identification in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross section, like objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist will not detect
objects out of the detection range.
