Lighting117Lighting features
Exit lighting
Headlights come on for approx.
30 seconds after the vehicle is parked
and the system is activated.
Activating 1. Switch off ignition.
2. Remove ignition key.
3. Pull stalk towards steering wheel.
This action can be repeated up to
four times.
The headlights are turned off immediately by turning the light switch
to any position and returning to 7.
Battery discharge protection To prevent discharge of the vehicle
battery when the ignition is switched
off, some interior lights may be
switched off automatically after some
time.
Climate control125Fan speed
Adjust the air flow to select the
desired speed.
turn clockwise:increase air flowturn anticlock‐
wise:decrease air flow
Notice
Rear air conditioning cannot be
switched on during an Autostop.
Stop-start system 3 138.
Combi
Additional air conditioning is supplied to the rear passenger compartment
via the air vents located above the
driver and front passenger
compartment.
With the front passenger
compartment air conditioning system
switched on, adjust the air flow to
select the desired speed.
Ensure the air vents are open when in
use, to prevent ice forming in the
system due to lack of air movement.
Auxiliary heaterCoolant heater
The engine-independent, fuel-
powered coolant heater provides
rapid heating of the engine coolant to
enable heating of the vehicle interior
without the engine running.
Notice
Depending on version, an additional
coolant heater may be switched on
automatically to speed up heating
when the ignition is on and the
outside temperature is below 5 ℃.9 Warning
Do not operate the system when
refuelling, when dust or
combustible vapours are present
or in enclosed spaces (e.g.
garage).
Before starting or programming the
system to start, turn the vehicle's
climate control system to heat, set the
air distribution to V and turn the fan
on.
Switch off when not required. Heating stops automatically after the
programmed runtime. It will also
cease to operate if the vehicle fuel
level drops too low.
During operation, power from the
vehicle battery is used. The driving
time should therefore be at least as
long as the heating time. For short
journey times, check the vehicle
battery regularly and recharge if
necessary.
To ensure efficient performance,
briefly operate the auxiliary heater
once a month.

136Driving and operatingCaution
Vehicles equipped with hydraulic
power steering:
If the steering wheel is turned until it reaches the end of its travel, and
is held in that position for more
than 15 seconds, damage may
occur to the power steering
system and there may be loss of
power steering assist.
Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys and after new
disc brake pads have been fitted.
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
vehicle battery.
Stop-start system 3 138.
Diesel particle filter 3 144.

Driving and operating137Steering wheel lockRemove key from ignition switch and
turn steering wheel until it engages.9 Danger
Never remove the key from
ignition switch during driving as
this will cause steering wheel lock.
Starting the engine
Manual transmission: operate clutch.
Manual transmission automated:
operate brake; transmission
automatically shifts to N.
Do not accelerate.
Turn the key to position 2 for
preheating, and hold until control
indicator N extinguishes from the
Driver Information Centre.
Notice
Depending on vehicle, if a gear is
engaged during preheating, a
message may appear in the Driver
Information Centre (DIC) 3 104
indicating that the clutch pedal must be depressed when starting the
engine.
Turn key to position 3 and release.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 15 seconds before
repeating starting procedure. If
necessary, depress accelerator
before repeating starting procedure.Notice
Rear-wheel drive: When starting on
a level surface with an unladen
vehicle, it is recommended that
second gear is selected when
starting off.
Before restarting or to switch off the
engine, turn key back to 0.
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Stop-start system 3 138.
Turbo engine warm-up
Upon start-up, engine available
torque may be limited for a short time, especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully
protect the engine.
Driving and operating139Deactivation
Deactivate the stop-start system
manually by pressing Î.
Deactivation is indicated when the
LED in the button illuminates.
To reactivate, press Î again. The
LED extinguishes in the button. The system is reactivated automatically
the next time the ignition is switched
on.
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 3 104.
Idle speed control 3 138.
AutostopManual transmission
If the vehicle is at low speed or
standstill, activate an Autostop as
follows:
● depress the clutch pedal
● move the selector lever to neutral
● release the clutch pedal
Control indicator Ï may flash if the
clutch is not released sufficiently.Manual transmission automated
If the vehicle is at a standstill, activate an Autostop as follows:
● selector lever in position N (or
A/M )
● depress brake pedal firmly
● do not accelerate
The engine will be switched off while
the ignition stays on if the required
conditions are fulfilled.
An Autostop is indicated when Ï
illuminates green in the instrument
cluster 3 103.
During an Autostop, the heating
performance, power steering and
brake performance will be
maintained. Brake assist, however, is
not available 3 158.
Notice
If you exit the vehicle while the
engine is in an Autostop, a warning
chime will sound as a reminder that
the engine is on standby and has not been switched off.
140Driving and operating9Warning
Switch off engine and ignition
before exiting the vehicle.
Conditions for an Autostop
The stop-start system checks if each
of the following conditions is fulfilled,
otherwise an Autostop will be
inhibited and control indicator \ will
illuminate in the instrument cluster.
● the stop-start system is not manually deactivated
● the bonnet is fully closed
● the vehicle battery is sufficiently charged and in good condition
● the engine is warmed up
● the engine coolant temperature is
not too high
● the ambient temperature is not too low
● the defrosting function is not activated
● the climate control system does not inhibit an Autostop
● the rear air conditioning system is
not activated
● the brake vacuum is sufficient
● the self-cleaning function of the diesel particle filter is not active
3 144
● the vehicle has moved since the last Autostop
Otherwise an Autostop will be
inhibited.
An Autostop may become
unavailable as the ambient
temperature approaches freezing
point.
Certain settings of the climate control
system may also inhibit an Autostop.
See "Climate control" chapter for
further information 3 118.
Immediately after motorway driving
an Autostop may be inhibited.
New vehicle running-in 3 136.
Vehicle battery discharge protection
To ensure reliable engine restarts, several vehicle battery discharge
protection features are implemented
as part of the stop-start system.Restart of the engine by the driverManual transmission
With the selector lever in neutral,
depress the clutch pedal to restart the
engine.
Notice
If any gear is selected, the clutch
pedal must be fully depressed to
restart the engine.
If the engine does not restart first
time, depress clutch pedal fully again.Manual transmission automated
With the selector lever in position N
(or A/M ) and the parking brake
released, release the brake pedal to
restart the engine.
Engaging reverse gear or depressing
the accelerator pedal may also restart the engine.
The green control indicator Ï will
extinguish in the instrument cluster
when the engine is restarted. If
certain conditions are not fulfilled, a
restart will not take place. Start using
the ignition key.
