3. Pull turn signal lever towards steering wheel.
This action can be repeated up to
four times.

Climate control121Fan speed
Adjust the air flow to select the
desired speed.
turn clockwise:increase air flowturn anti-clock‐
wise:decrease air flow
Notice
Rear air conditioning cannot be
switched on during an Autostop.
Stop-start system 3 134.
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.

132Driving 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 3 134.
Diesel particle filter 3 140.

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) 3 100
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 3 134.
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.
