If the V button is pressed while the
engine is in an Autostop, the engine will restart automatically.Electronic climate control

The preselected temperature is
automatically regulated. In the
automatic mode the fan speed and air distribution automatically regulate the

The system can be manually adapted by use of air distribution and air flowcontrols.
The electronic climate control system
is only fully operational when the

Driving and operating111Idle speed control
To increase the idle speed press the
switch. After a few seconds the
function will be activated.
The function will be deactivated
when:
■ The clutch pedal is depressed
■ The accelerator pedal is depressed
■ MTA is not in neutral N
■ Vehicle speed is above 0 mph
■ Control indicator A, W or C
illuminate in the instrument cluster
To increase or decrease the fast idle
speed rate, consult a workshop.
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 the stop-start
Î button. Deactivation is indicated
when the LED in the button
illuminates.

128Driving and operating
Deactivation
Press switch §: speed limiter is
deactivated and the vehicle can be
driven normally.
The limit speed is stored and a
corresponding message appears in
the Driver Information Centre.
Reactivation
Press switch R. The speed limiter
function is reactivated.
Deleting the limit speed
Press switch U.
Yellow control indicator U
extinguishes in the instrument cluster.
Parking 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 ultrasonic
parking 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 1 ft, 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,
