50Seats, restraints
To restore, lift backrest to upright
position and engage. The seat slides
automatically backwards to the
original position.
In case the head restraint of the
folded backrest is blocked by the
upper windscreen frame, allow the
seat to move backwards or
downwards slightly 3 50, or set
head restraint to lowest position
3 44.
Safety function
If the power seat encounters
resistance while sliding forwards or
rearwards, it is immediately stopped
and moved in the opposite direction.
Notice
Do not sit on the seat while seat is
moving.
Power disconnection
If seat remains in forward position
with opened door for more than
10 minutes, power adjustment is
disconnected. In this event, close and open the door or switch on ignition
and operate power adjustment again.Overload
If the folding function is electrically
overloaded, the power supply is
automatically cut-off for a short time.
Power seat adjustment9 Warning
Care must be taken when
operating the power seats. There
is a risk of injury, particularly for
children. Objects could become
trapped.
Keep a close watch on the seats
when adjusting them. Vehicle
passengers should be informed
accordingly.

114Lighting
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 stay activated.
High beam assist is always active
after the ignition is switched on.
Intelligent light ranging with automatic high beam activation
Intelligent light ranging uses the
properties of Bi-Xenon headlights to
extend the light range of the low beam by up to 400 metres and additionally
activates automatic high beam
without dazzling or disturbing
oncoming or preceding traffic.
High beam is deactivated and the low
beam light range is reduced to avoid
dazzling when the following
restrictions are detected by the front
camera in the windscreen:
■ a preceding vehicle is recognised,
■ an oncoming vehicle is recognised,
■ urban areas are entered,
■ it is foggy or snowy.If there are no restrictions detected,
the system switches back to high
beam.
When the system is active, the front
camera monitors the area ahead of
the vehicle and ensures an optimum light distribution for maximum drivervision during almost all conditions.
Intelligent light ranging with automatic
high beam activation therefore
reduces the difference between
conventional low and high beam
without drastic changes in light-
range, distribution and intensity.A special topographical evaluation
function detects preceding vehicles
on hills or slopes by recognising the
rear light moving ahead. The system
adjusts the height of the light range to
ensure optimum illumination on the
road ahead without dazzling.
Activation
Intelligent light ranging and automatic
high beam activation are switched on together by pushing the indicator
lever twice. They can be switched on
with ignition on.

Driving and operating163
The system can be activated or
deactivated in the menu Settings in
the Info-Display, vehicle
personalisation 3 102.
Deactivation is indicated by a
message in the Driver Information
Centre.
Detection zones
The system sensor covers a zone of
approx. 3 metres on both sides of the
vehicle. This zone starts at each
exterior mirror and extends rearwards by approx. 3 metres. The height of the zone is approx. between 0.5 metres
and 2 metres off the ground.
The system is deactivated if the
vehicle is towing a trailer.
Side blind spot alert is designed to ignore stationary objects such as
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming
vehicles are not detected.
Fault
Occasional missed alerts can occur
under normal circumstances.Side blind spot alert does not operate when the left or right corners of the
rear bumper are covered with mud,
dirt, snow, ice or slush. Cleaning
instructions 3 218.
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.
Rear view camera
The rear view camera assists the
driver when reversing by displaying a view of the area behind the vehicle.
The view of the camera is displayed
in the Colour-Info-Display.9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view and the
advanced parking assist sensors,
e.g. below the bumper or
underneath the vehicle, are not
displayed.
Do not reverse the vehicle by only looking at the Info-Display and
check the surrounding area
behind and around the vehicle
before reversing.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged.

The ignition system and Xenon
headlights use extremely high
voltage. Do not touch.
Bonnet
Opening
Pull the release lever and return it to
its original position.
Move the safety catch sideways to the left vehicle side and open the bonnet.
Secure the bonnet support.
If the bonnet is opened during an
Autostop, the engine will be restarted automatically for safety reasons.
Closing Before closing the bonnet, press the
support into the holder.
Lower the bonnet and let it fall into the
latch from a low height (20-25 cm).
Check that the bonnet is engaged.Caution

latch to avoid dents.
Engine oil
Check the engine oil level manually on a regular basis to prevent damage
to the engine. Ensure that the correct
specification of oil is used.

200Vehicle careWheels and tyres
Wheels
On vehicles with Diesel engines no
steel rims and only special, for this
vehicle approved alloy wheels are
permitted.
Tyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Winter tyres Winter tyres improve driving safety attemperatures below 7 °C and should
therefore be fitted on all wheels.
All tyre sizes are permitted as winter
tyres 3 234.Use tyre size 225/55 R17 only as
winter tyres.
On vehicles with Diesel engines, no
steel rims and only special, vehicle-
approved alloy wheels are permitted.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
