52Seats, 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 52, or set
head restraint to lowest position
3 46.
Safety function
If the power seat encounters
resistance while sliding forwards or
rearwards, it is immediately stopped
and moved in the opposite direction.
Note
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.
Seat lengthwise adjustment
Move switch forwards/backwards.

116Lighting
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 operating1659Warning
Side blind spot alert does not
replace driver vision.
The system does not detect: ■ Vehicles outside the side blind zones which may be rapidly
approaching.
■ Pedestrians, cyclists or animals.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects a vehicle in the side blind zone while driving
forward, either while passing a
vehicle or being passed, an amber warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol B starts flashing
amber as a warning not to change
lanes.
Note
If the passing vehicle is at least
10 km/h faster than the passed
vehicle, the warning symbol B in the
relevant exterior mirror will not
illuminate.
Side blind spot alert is active from
speeds of 10 km/h up to 140 km/h.
Driving faster than 140 km/h
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the speed again will extinguish the
warning symbols. If a vehicle is then
detected in the blind zone, the
warning symbols B will illuminate as
normal on the relevant side.
When the vehicle is started, both exterior mirror displays will briefly
come on to indicate that the system is operating.
The system can be activated or
deactivated in the menu Settings in
the Info-Display, vehicle
personalisation 3 104.
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.

Vehicle care1839Danger
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
Do not press the bonnet into the
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.
Recommended fluids and lubricants
3 227.
Check with the vehicle on a level
surface. The engine must be at
operating temperature and switched
off for at least 5 minutes.

204Vehicle 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 3 239.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.

Fit directional tyres such that they roll in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure Check the pressure of cold tyres atleast every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Unscrew the valve cap.
