Wheels and tyres
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.
We recommend not swapping the
front wheels with the rear wheels and vice versa, as this can affect vehicle
stability. Always use less worn tyres on the rear axle.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.Tyre designations
E.g. 195/55 R 16 95 H195:tyre width, mm55:cross-section ratio (tyre height
to tyre width), %R:belt type: RadialRF:type: RunFlat16:wheel diameter, inches91:load index e.g. 91 is equivalent

Choose a tyre appropriate for the
maximum speed of your vehicle.
The maximum speed is achievable at kerb weight with driver (75 kg) plus
125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.

Vehicle care153Directional tyresDirectional tyres must be mounted so
that they rotate in the correct
direction. The proper rotation
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at least every 14 days and before any
long journey.
Do not forget the spare wheel.
This also applies to vehicles with tyre pressure monitoring system.
Tyre pressure 3 184.
The tyre pressure information label
on the driver's door frame indicates
the original equipment tyres and the
correspondent tyre pressures.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
The ECO tyre pressure serves to
achieve the smallest amount of fuel
consumption possible.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options.
For the correct tyre pressure value,
follow the procedure below:
● Identify the engine identifier code.
Engine data 3 180.
● Identify the respective tyre.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle or other national registration
documents.The driver is responsible for correct adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
If the tyre pressure must be reduced
or increased, switch off ignition. After
adjusting tyre pressure switch on
ignition and select the relevant setting on the page Tyre Load in the Driver
Information Centre 3 76.
Page 156 of 201

154Vehicle careTemperature dependencyThe tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
The tyre pressure value displayed in
the Driver Information Centre shows
the real tyre pressure. A cooled down
tyre will show a decreased value,
which does not indicate an air leak.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
checks the pressure of all four tyres
once a minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only 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.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle operating permit.
The current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information
Centre.
The menu can be selected by
pressing the buttons on the stalk.
Press MENU to select the Vehicle
Information Menu X.
Turn the adjuster wheel to select the
tyre pressure monitoring system.

Vehicle care155System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
Driver Information Centre.
The system considers the tyre
temperature for the warnings.
Temperature dependency 3 153.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 74.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 184.
If
w flashes for 60-90 seconds then
illuminates continuously, there is a
fault in the system. Consult a
workshop.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure.
Vehicle messages 3 82.
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 temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these tyres.
Control indicator w illuminates. For
the further three tyres, 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.
Operating electronic devices or being close to facilities using similar wave
frequencies 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 the
clipped sensor; replace complete
valve stem.
Vehicle loading status
Adjust tyre pressure to load condition according to the tyre information labelor tyre pressure chart 3 184, and
select the appropriate setting in the menu Tyre Load in the Driver
Information Centre, Vehicle
Information Menu 3 76 . This setting is
the reference for the tyre pressure
warnings.
Page 158 of 201

156Vehicle careThe Tyre Load menu 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:
● Lo for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Hi for full loading.
Tyre pressure sensor matching
process
Each tyre pressure 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
tyre pressure sensors were replaced. The tyre pressure sensor matching
process should also be performed
after replacing a spare tyre with a
road tyre containing the tyre pressure 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 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 light at the current active position
is illuminated until sensor is matched.
Consult a workshop for service. There
are 2 minutes to match the first wheel position, and 5 minutes overall tomatch 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 manual transmission: select neutral.
4. Use MENU on the stalk to select
the Vehicle Information Menu in
the Driver Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
6. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should be
displayed.
7. Press SET/CLR again to confirm
the selection. The horn sounds
twice to indicate that the receiver
is in relearn mode.
8. Start with the left side front wheel.
9. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
Page 159 of 201

Vehicle care157the tyre pressure sensor. A horn
chirp confirms that the sensor
identification code has been
matched to this wheel position.
10. Proceed to the right side front wheel, and repeat the procedure
in Step 9.
11. Proceed to the right side rear wheel, and repeat the procedure
in Step 9.
12. Proceed to the left side rear wheel, and repeat the procedure
in Step 9. The horn sounds twice
to indicate that the sensor
identification code has been
matched to the left side rear
wheel, and the tyre pressure
sensor matching process is no
longer active.
13. Turn off the ignition.
14. Set all four tyres to the recommended air pressure level
as indicated on the tyre
information label.
15. Ensure the tyre loading status is set according to the selected
pressure 3 76.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
indicators (TWI). Their position is
indicated by markings on the
sidewall.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel size
If tyres of a different size than those fitted at the factory are used, it may be necessary to reprogramme the
nominal tyre pressure and make
other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced 3 154.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Page 160 of 201

158Vehicle careWheel coversWheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the
relevant wheel and tyre combination
requirements must be used.
If the wheel covers and tyres used are
not factory approved, the tyres must
not have a rim protection ridge.
Wheel covers must not impair brake
cooling.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
Tyre chains
Tyre chains are only permitted on the
front wheels.
Always use fine mesh chains that add no more than 10 mm to the tyre tread
and the inboard sides (including chain lock).
9 Warning
Damage may lead to tyre blowout.
Tyre chains are only permitted on
tyres of size 165/65 R14.
Tyre chains are not permitted on tyres of size 185/55 R15 and 195/45 R16.
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that is at the tyre's sidewall cannot be
repaired with the tyre repair kit.9 Warning
Do not drive faster than 50 mph.
Do not use for a lengthy period.
Steering and handling may be
affected.
If you have a flat tyre:
Apply the parking brake and engage
first gear or reverse gear.
