Driving and operating207Lane departure warningThe lane departure warning system
observes the lane markings between
which the vehicle is driving via a front
camera. The system detects lane
changes and warns the driver in the
event of an unintended lane change
via visual and acoustic signals.
Criteria for the detection of an
unintended lane change are:
● No operation of turn signals.
● No brake pedal operation.
● No active accelerator operation or speeding-up.
● No active steering.
If the driver is active, no warning will
be issued.Activation
The lane departure warning system is activated by pressing ). The
illuminated LED in the button
indicates that the system is switched
on. When the control indicator ) in
the instrument cluster illuminates
green, the system is ready to operate.
The system is only operable at
vehicle speeds above 35 mph and if
lane markings are available.
When the system recognises an
unintended lane change, the control
indicator ) changes to yellow and
flashes. Simultaneously a chime
sound is activated.
Deactivation
The system is deactivated by
pressing ), the LED in the button
extinguishes.
At speeds below 35 mph the system
is inoperable.
Fault
The lane departure warning system
may not operate properly when:
● The windscreen is not clean.
● There are adverse environmental
conditions like heavy rain, snow,
direct sunlight or shadows.
Driving and operating211Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Faults and remedies
If gas mode is not possible, check the
following:
● Is there enough liquid gas present?
● Is there enough petrol present for
starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.
In extreme situations, the system may also switch back to petrol mode if the
minimum requirements are not
fulfilled. If conditions allow, it might be
possible to manually switch back to
liquid gas operation.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If the gas odour persists, do not start
the engine. Have the cause of the
fault remedied by a workshop.
When using underground car parks,
follow the instructions of the operator
and local laws.
Notice
In the event of an accident, switch off
the ignition and lights.
Refuelling9 Danger
Before refuelling, switch off
ignition and any external heaters
with combustion chambers.
Switch off any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
Driving and operating213Vehicles with misfuel inhibitor9Warning
Do not try to open the flap of the
fuel filler neck manually on
vehicles with misfuel inhibitor.
Disregarding this could lead to
trapping of the fingers.
Vehicles with a selective catalytic
reduction system are equipped with a
misfuel inhibitor.
The misfuel inhibitor ensures that the flap of the fuel filler neck can only be
opened by using a nozzle for diesel
fuel or a funnel for emergency
refilling.
Turn the fuel filler cap slowly
anticlockwise.
The cap can be retained in the
bracket on the fuel filler flap.
Place the nozzle in a straight line to the filler neck and press with slight
force to insert.
In case of an emergency refill with a
canister, a funnel must be used to
open the cap of the filler neck.The funnel is located on the right-
hand side storage compartment in the load compartment.
Place the funnel in a straight line to
the filler neck and press with slight force to insert.
Use the funnel to fill the diesel fuel into
the filler neck.
After topping-up, put the funnel into
the plastic bag and stow it in the storage compartment.

Natural gas refuelling
224Vehicle carewebsite, where legally required. Only
entrust this work to an authorised
recycling centre.
Gas vehicles must be recycled by a
service centre authorised for gas
vehicles.Vehicle checks
Performing work9 Warning
Only perform engine compartment
checks when the ignition is off.
The cooling fan may start
operating even if the ignition is off.
9 Danger
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.
230Vehicle careCharging the vehicle battery9Warning
On vehicles with stop-start
system, ensure that the charging potential does not exceed
14.6 volts when using a battery
charger. Otherwise the vehicle
battery might be damaged.
Jump starting 3 260.
Warning label
Meaning of symbols: ● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
● See the Owner's Manual for further information.
● Explosive gas may be present in the vicinity of the vehicle battery.
Diesel fuel system bleeding If the tank has been run dry, the diesel
fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of 40 seconds. Repeat this process after
no less than 5 seconds. If the engine fails to start, seek the assistance of a
workshop.Wiper blade replacement
Lift the wiper arm until it stays in the
raised position, press button to
disengage the wiper blade and
remove.
Attach the wiper blade slightly angled
to the wiper arm and push until it
engages.
Lower wiper arm carefully.
Vehicle care249Each time the tyres are replaced, tyre
pressure monitoring system sensors
must be dismounted and serviced. For the screwed sensor, replace
valve core and sealing ring. For
clipped sensor, replace complete
valve stem.
Vehicle loading status
Adjust tyre pressure to load condition according to the tyre information labelor tyre pressure chart 3 288, and
select the appropriate setting in the
Tyre load menu in the Driver
Information Centre 3 116. This
setting is the reference for the tyre
pressure warnings.
The menu Tyre Load only appears if
the vehicle is in a standstill and the
parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.
Select:
● Light for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Max for full load.
TPMS sensor matching process Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new
wheel position after rotating the
wheels or exchanging the complete
wheel set and if one or more TPMS
sensors were replaced. The TPMS sensor matching process should also
be performed after replacing a spare
wheel with a road wheel containing
the TPMS sensor.
The malfunction light w and the
warning message or code should go
off at the next ignition cycle. The
sensors are matched to the wheel
positions, using a TPMS relearn tool,
in the following order: left side front
wheel, right side front wheel, right
side rear wheel and left side rear
wheel. The turn signal light at the
current active position is illuminated
until sensor is matched.
Consult your workshop for service or
to purchase a relearn tool. There are
2 minutes to match the first wheel
position, and 5 minutes overall to
match all four wheel positions. If it
takes longer, the matching process
stops and must be restarted.
The TPMS sensor matching process
is:
1. Apply the parking brake; on vehicles with automatic
transmission set the selector lever
to P.
2. Turn the ignition on.
