system
The adjusting screws are located
above the headlight.
Turn the adjusting screws with the
screwdriver clockwise by half a turn.
For deactivation, turn the adjusting
screws counterclockwise by half a
turn.
Caution
Have the adjustment of the
headlights checked after
deactivation.
We recommend consulting a
workshop.
Vehicles with adaptive forward
lighting system

The headlights are aimed
automatically.
Every time the ignition is switched on,
f flashes as a reminder for approx. 4
seconds.
For deactivation operate the same
procedure as described above. f will
not flash when function is
deactivated.

Reversing functionIf the headlights are on and reverse
gear is engaged, both corner lights
are switched on. They remain
illuminated for 20 seconds after
disengaging reverse gear or until
driving faster than 17 km/h in a
forward gear.
High beam assist
This feature allows high beam as
main driving light by night and when
vehicle speed is faster than 40 km/h.
It switches to low beam when: ■ the camera in the windscreen detects the lights of oncoming or
preceding vehicles
■ the vehicle speed is slower than 20 km/h
■ it is foggy or snowy
■ driving in urban areasActivation
The high beam assist is activated by
pushing the indicator lever twice at a
speed above 40 km/h.
The green control indicator l
illuminates continuously when the
assist is activated, the blue one 7
illuminates when high beam is on.
Control indicator l 3 88.
Deactivation
Push indicator lever once. It is also
deactivated when front or rear fog
lights are switched on.
If a headlight flash is activated when
the high beam is on, the high beam
assist will be deactivated.
If a headlight flash is activated when
the high beam is off, the high beam
assist will remain activated.
High beam assist is always active
after the ignition is switched on.
Dynamic automatic headlight
levelling
To prevent oncoming traffic from dazzle, headlight levelling is
automatically adjusted based on
inclination information measured by
front and rear axle, acceleration or
deceleration and vehicle speed.
Fault in Adaptive forward
lighting system When the system detects a failure in
the Adaptive forward lighting system,
the system moves to a preset position to avoid dazzling of oncoming traffic.
Have the cause of the failure
remedied by a workshop as soon as
possible.

Misted light covers
The inside of the light housing may
mist up briefly in poor, wet and cold weather conditions, in heavy rain or
after washing. The mist disappears
quickly by itself; to help switch on the
headlights.Interior lighting

Climate control119
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
might inhibit Autostops.
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.Air vents
Adjustable air vents
At least one air vent must be open
while the cooling is on.
To open the vent, turn the adjuster
wheel to the right. Adjust the air
amount at the vent outlet by turning
the adjuster wheel.

122Driving and operatingStarting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
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
battery.

Manual transmission: operate clutch.
Automatic transmission: operate
brake and move the selector lever to
P or N.
Do not operate the accelerator pedal. Diesel engine: turn the key to position2 for preheating until control
indicator ! extinguishes.
Turn the key briefly to position 3 and
release: an automatic procedure
operates the starter with a short delay
as long as the engine is running, see
Automatic Starter Control.

Driving and operating123
Before restarting or to switch off the
engine, turn the key back to position
0 .
During an Autostop, the engine can
be started by depressing the clutch
pedal.
Key lock release
Some vehicles with an automatic
transmission are equipped with an electronic key lock release system.
The key lock release is designed to
prevent ignition key removal unless
the selector lever is in P.
Starting the vehicle at low
temperatures
Starting the engine without additional
heaters is possible down to -25 °С for diesel engines and -30 °C for petrol
engines. Required is an engine oil
with the correct viscosity, the correct fuel, performed services and a
sufficiently charged battery. With
temperatures below -30 °C the
automatic transmission requires a
warming phase of approx. 5 minutes.
The selector lever must be in position P .Automatic Starter Control
This function controls the engine
starting procedure. The driver does
not have to hold the key in position 3.
Once applied, the system will go on starting automatically until the engine
is running. Because of the checking
procedure, the engine starts running
after a short delay.
Possible reasons for a non-starting
engine:
■ Clutch pedal not operated (manual transmission)
■ Brake pedal not operated or selector lever not in P or N
(automatic transmission)
■ Timeout occurred
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.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
emissions. 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 battery sensor ensures
that an Autostop is only performed if
the 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.
