50Seats, restraintsFront airbag systemThe front airbag system consists of
one airbag in the steering wheel and
one in the instrument panel on the
front passenger side. These can be
identified by the word AIRBAG.
Additionally there is a warning label
on the side of the instrument panel,
visible when the front passenger door
is open.
The front airbag system is triggered in
the event of an accident of a certain
severity. The ignition must be
switched on.
The inflated airbags cushion the
impact, thereby reducing the risk of
injury to the upper body and head of
the front seat occupants
considerably.9 Warning
Optimum protection is only
provided when the seat is in the
proper position 3 37.
Keep the area in which the airbag
inflates clear of obstructions.
Fit the seat belt correctly and
engage securely. Only then the
airbag is able to protect.
Side airbag system
The side airbag system consists of an
airbag in each front seat backrest.
This can be identified by the word
AIRBAG .
The side airbag system is triggered in the event of an accident of a certain
severity. The ignition must be
switched on.
The inflated airbags cushion the
impact, thereby reducing the risk of
injury to the upper body and pelvis in
the event of a side-on collision
considerably.

Illuminates when the engine is
runningCaution
Engine lubrication may be
interrupted. This may result in
damage to the engine and/or
locking of the drive wheels.
1. Depress clutch.
2. Select neutral gear, set selector lever to N.
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.
Check oil level before seeking
assistance of a workshop 3 140.

Lighting91
If the vehicle is equipped with theautomatic light control function, the
system switches between daytime
running lights and headlights
automatically depending on the
lighting conditions. Automatic light
control 3 89.
Adaptive forward lighting Cornering light
Depending on the steering angle,
vehicle speed and gear selected
when cornering, an additional light
will illuminate the corner of the road
on the respective side.
The cornering light is switched off
automatically after prolonged use and at vehicle speeds above 25 mph.Hazard warning flashers
Operated with the ¨ button.
In the event of hard braking, the
hazard warning flashers may turn on
automatically. Switch off by pressing
the ¨ button.
Turn and lane-change
signalsLever up=right turn signalLever down=left turn signal
When the steering wheel is turned
back, the lever automatically returns
to its original position and the
indicator is deactivated. This will not happen when making a minor
steering manoeuvre such as lane
changing.

Lighting95Lighting featuresExit lighting
Headlights come on for approx.
1 minute after the vehicle is parked
and the system is activated.
Activating 1. Switch off ignition.
2. Remove ignition key.
3. Pull turn signal lever 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.

Driving and operating109
systems function during an Autostop,
but there will be a controlled reduction
in power steering assist and vehicle
speed is reduced.
Stop-start system 3 111.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in the area of the pedals.
Steering If power steering assist is lost
because the engine stops or due to a system malfunction, the vehicle can
be steered but may require increased
effort.Caution
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.

Driver Information Centre.
Turn key to position D 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.
Before restarting or to switch off the
engine, turn key back to St.
During an Autostop, the engine can be started by depressing the clutch
pedal. Stop-start system 3 111.
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.

136Driving and operating
The pitch of the audible warning will
change if a turn signal light on the
trailer or the towing vehicle fails.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While the system is working,keep steering wheel as still as
possible.
Trailer stability assist (TSA) is a
function of the Electronic stability
program (ESP) 3 125.Auxiliary features
