Driving and operating227Alternatively, SET/CLR can be
pressed for three seconds to clear the
content of the page.
Upon successful reset, a chime will
sound and the following “Default
Sign” is indicated until the next traffic
sign is detected.
In some cases, traffic sign assistant is
cleared up automatically by the
system.
Clearing of traffic signs
There are different scenarios that
lead to clearing the currently
displayed traffic signs. After clearing,
the “Default Sign” is displayed in the
Driver Information Centre.
Reasons for signs being cleared:
● A predefined distance was driven
or time has elapsed (differs for
each sign type)
● Vehicle drives through a turn
● The speed becomes slower than 52 km/h (city entry detection)
Fault
The traffic sign assistant system may
not operate correctly if:
● The area of the windscreen, where the front camera is
located, is not clean or affected
by foreign items, e.g. stickers.
● Traffic signs are completely or partially covered or difficult to
discern.
● There are adverse environmental
conditions, e.g. heavy rain, snow,direct sunlight or shadows.
● Traffic signs are incorrectly mounted or damaged.
● Traffic signs do not comply with the Vienna Convention on traffic
signs.Caution
The system is intended to help the driver within a defined speed
range to discern certain traffic
signs. Do not ignore traffic signs
which are not displayed by the
system.
The system does not discern any other than the conventional traffic
signs that might give or end a
speed limit.
Do not let this special feature
tempt you into taking risks when
driving.
Always adapt speed to the road
conditions.
The driver assistance systems do not relieve the driver from full
responsibility for vehicle
operation.
Lane departure warning
The lane departure warning system
observes the lane markings between
which the vehicle is driving via a front camera. The system detects lane
228Driving and operatingchanges 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.
ActivationThe lane departure warning system isactivated 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 56 km/h 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 56 km/h 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.
The system can not operate when no
lane marking is detected.
232Driving and operating
The fuel filler cap can be retained in
the bracket on the fuel filler flap.
To refuel, fully insert the pump nozzle
and switch it on.
After the automatic cut-off, the tank can be topped up by operating the
pump nozzle a maximum of two more
times.
Caution
Wipe off any overflowing fuel
immediately.
To close, turn the fuel filler cap
clockwise until it clicks.
Close the flap and engage.
Vehicles with misfuel inhibitor9 Warning
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.
246Vehicle careWarning 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 five seconds. If the
engine fails to start, seek the
assistance of a workshop.Wiper blade replacement

Vehicle care265
Select Tyre load page under Vehicle
Information Menu ? in the Driver
Information Centre 3 101.
Select: ● Light for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Max for full load.
Tyre pressure sensor matching
process
Each tyre pressure 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
tyre pressure sensors were replaced. The tyre pressure sensor matching
process should also be performed
after replacing a spare wheel with a
road wheel containing the tyre
pressure sensor.
The malfunction light w and the
warning message or code should
extinguish at the next ignition cycle.
The sensors are matched to the
wheel positions, using a 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.
There are two minutes to match the
first wheel position, and five minutes
overall to match all four wheel
positions. If it takes longer, the
matching process stops and must be
restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.2. Turn the ignition on.
3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission: select neutral.
4. Press MENU on the turn signal
lever to select the Vehicle
Information Menu ? in the
Driver Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
