200Driving and operating
■traffic signs are incorrectly mounted
or damaged
■ traffic signs do not comply with the Vienna Convention on traffic signs
(Wiener Übereinkommen über
Straßenverkehrszeichen)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 systemobserves 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
by 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 ) button.
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.
236Vehicle care
In right-hand drive vehicles, the fuse
box is located behind a cover in the
glovebox. Open the glovebox and
remove the cover.

Vehicle care241Caution
Tyre pressure monitoring system
warns just about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
Select the Tyre pressure monitoring
page under the Info Menu in the
Driver Information Centre 3 106
System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
Driver Information Centre.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 103.
If w lights up, stop as soon as
possible and inflate the tyres as
recommended 3 288.
After inflating driving may be required
to update the tyre pressure values in
the Driver Information Centre. During
this time w may light up.
If w lights up at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting
low pressure. Check tyre pressure.
Vehicle messages 3 115.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. Control indicator w
illuminates. For the further three
wheels the system remains
operational.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory
approved repair kits can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each 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.
242Vehicle care
Vehicle loading statusAdjust tyre pressure to load condition according tyre information label or
tyre pressure chart 3 288, and select
the according setting in the Tyre
loading page under the Settings
menu in the Driver Information Centre
3 106.
Select:
■ Light for comfort pressure up to
3 people
■ Eco for Eco pressure up to
3 people
■ Max for full loading
Auto learn function
After changing wheels the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn process takes up to 10 minutes of
driving with a minimum speed of
12 mph. In this case $ can be
displayed or pressure values can
swap in the Driver Information Centre.
If problems occur during the relearn
process, a warning message is
displayed in the Driver Information
Centre.
Temperature dependency Tyre pressure depends on the
temperature of the tyre. During
driving tyre temperature and pressure increase.
The tyre pressure value displayed in
the Driver Information Centre shows
the actual tyre pressure. Therefore it
is important to check tyre pressure
with cold tyres.Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons, it is
recommended that the tread depth of
the tyres on one axle should not vary
by more than 2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
Vehicle care259
Clean the leather upholstery with
clear water and a soft cloth. In case of
heavy soiling, use leather care.
The instrument cluster and the
displays should only be cleaned using a soft damp cloth. If necessary use aweak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water
or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
Plastic and rubber parts
Plastic and rubber parts can be
cleaned with the same cleaner as
used to clean the body. Use interior cleaner if necessary. Do not use any
other agent. Avoid solvents and petrol in particular. Do not use high-
pressure jet cleaners.

Confirmations
Confirmation of service is recorded in the Service and Warranty Booklet.The date and mileage is completed
with the stamp and signature of the
servicing workshop.
Service and maintenance261
Make sure that the Service and
Warranty Booklet is completed
correctly as continuous proof of
service is essential if any warranty or goodwill claims are to be met, and is
also a benefit when selling the
vehicle.
Service interval with remaining
engine oil life duration The service interval is based on
several parameters depending on
usage.
The service display lets you know
when to change the engine oil.
Service display 3 97.Recommended fluids,
lubricants and parts
Recommended fluids and
lubricants
Only use products that meet the
recommended specifications.
Damage resulting from the use of
products not in line with these
specifications will not be covered by
the warranty.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for
gasoline and diesel engines. If it is unavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 265.
Topping up engine oil
Engine oils of different manufacturers
and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
