All wheels must be equipped with
pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information Centre
(DIC).
The menu can be selected by the
buttons on the turn signal lever.Press the MENU button to select the
Vehicle Information Menu X .
Turn the adjuster wheel to select the
tyre pressure monitoring system.
System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
DIC.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 87.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 210.
If w flashes for 60-90 seconds and
then illuminates continuously, there is a fault in the system. Consult a
workshop.
After inflating, driving may be
required to update the tyre pressure
values in the DIC. During this time w
may illuminate.
Vehicle care179
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting
low pressure. Check tyre pressure.
Vehicle messages 3 95.
If the tyre pressure shall 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 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.
Vehicle loading status
Adjust tyre pressure to load condition according to tyre information label or
tyre pressure chart 3 210, and select
the relevant setting in the menu Tire
Load in the Driver Information Centre,
Vehicle Information Menu 3 90.Select:
■ Light for comfort pressure up to
3 people
■ Eco for Eco pressure up to
3 people
■ Max for full loading
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new tyre/
wheel position after rotating the tyres
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 tyre
with a road tyre containing the TPMS
sensor.
The malfunction light and the warning
message or code should go off at the
next ignition cycle. The sensors are
matched to the tyre/wheel positions,
using a TPMS relearn tool, in the
following order: left side front tyre,
right side front tyre, right side rear
tyre, and left side rear.
180Vehicle care
Consult your workshop for service or
to purchase a relearn tool. There are
two minutes to match the first tyre/
wheel position, and five minutes
overall to match all four tyre/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.
3. Use the MENU button on the turn
signal lever to select the Vehicle
Information Menu in the Driver
Information Centre (DIC).
4. Turn the adjuster wheel to scroll to
the tyre pressure menu.
5. Press the SET/CLR button to
begin the sensor matching process. A message requesting
acceptance of the process should display.6. Press the SET/CLR button again
to confirm the selection. The horn
sounds twice to signal the
receiver is in relearn mode.
7. Start with the left side front tyre.
8. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the TPMS sensor. A horn chirp
confirms that the sensor
identification code has been
matched to this tyre and wheel
position.
9. Proceed to the right side front tyre,
and repeat the procedure in Step 8.
10. Proceed to the right side rear tyre,
and repeat the procedure in
Step 8.
11. Proceed to the left side rear tyre, and repeat the procedure inStep 8. The horn sounds twice to
indicate the sensor identification
code has been matched to the
driver side rear tyre, and the
TPMS sensor matching process
is no longer active.12. Turn off the ignition.
13. Set all four tyres to the recommended air pressure level
as indicated on the tyre pressure
label.
14. Ensure the tyre loading status is set according selected pressure
3 90.
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).
Vehicle care195
Paintwork damageRectify minor paintwork damage witha touch-up pen before rust forms.
Have more extensive damage or rust areas repaired by a workshop.
Underbody Some areas of the vehicle underbody
have a PVC undercoating while other
critical areas have a durable
protective wax coating.
After the underbody is washed, check the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.Liquid gas system9 Danger
Liquid gas is heavier than air and
can collect in sink points.
Take care when performing work
at the underbody in a pit.
For painting work and when using a
drying booth at a temperature above
60 °C, the liquid gas system must be
completely evacuated.
Do not make any modifications to the
liquid gas system.
Towing equipment Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.
Rear carrier system Clean the rear carrier system with a
steam-jet or high-pressure jet cleaner
at least once a year.
Operate the rear carrier system
periodically if not in regular use, in
particular during winter.
Interior care
Interior and upholstery Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
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 a
weak 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.

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.
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 81.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
specifiations 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
3 202.
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.
