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.
Use the valve cap key to make
unscrewing the valve caps easier.
The valve cap key is located on the
inside of the tank flap.
Tyre pressure 3 212.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
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:
1. Identify the engine identifier code.
Engine data 3 207.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 212.
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 on a vehicle with tyre
pressure monitoring system, switch
off ignition.
Temperature dependency
The 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
10 kPa for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
Vehicle care183The tyre pressure value displayed in
the Info-Display shows the real tyre
pressure. A cooled down tyre will
show a decreased value, which does
not indicate an air leak.
Tyre pressure monitoring system
The tyre pressure monitoring system
checks the pressure of all four wheels
once per 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. If
wheels without sensors are mounted,
the tyre pressure monitoring system
is not operational.
Note
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 tyre pressure sensors monitor
the air pressure in the tyres and
transmit tyre pressure readings to a
receiver located in the vehicle.
Each tyre, including the spare, should be checked monthly when cold and
inflated to the recommended inflation
pressure 3 212.
Low tyre pressure conditionA detected low tyre pressure
condition is indicated by control
indicator w 3 88.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 212.
When the system detects a
malfunction, w will flash for approx.
one minute and then remain
continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When w is illuminated, the system
may not be able to detect or signal low tyre pressure as intended.
If w illuminates at lower temperatures
and extinguishes after driving, this
could be an indicator for approaching
a low tyre pressure condition. Check
tyre pressure.
184Vehicle careTyre pressures in Info-Display
The current tyre pressures can be
shown in the menu item Tyres in the
Board Computer menu. Press BC on
the Infotainment system and select
the menu item.
The tyre pressure monitoring system
automatically detects the vehicle
load. A corresponding message may appear on the Info-Display if
inconsistent tyre pressures are
detected. In some versions, the
message is displayed in abbreviated
form.
For example, the following messages can be displayed:
A graphic indicating the left rear tyre
is shown together with the current tyre
pressure; slight pressure deviation.
Reduce speed. Check tyre pressure
at next opportunity with an
appropriate gauge and correct if
necessary.
On the Colour-Info-Display, this
message will appear in yellow.A graphic indicating the front left tyre
is shown together with the current tyre
pressure; significant pressure
deviation or direct pressure loss.
Steer out of the flow of traffic as
quickly as possible without
endangering other vehicles. Stop and
check the tyres. Mount the spare
wheel if necessary 3 190.
On the Colour-Info-Display, this
message will appear in red.

Vehicle care185If the tyre pressure is to be reduced or
increased, switch off the ignition. Tyre
pressures 3 182, 3 212.
General information The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved tyre repair kits can be used.
Tyre repair kit 3 187.
Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
The tyre pressure monitoring system
valve cores and sealing rings must be
replaced each time the tyres are
changed.
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 replacing one or
more of the tyre pressure sensors.The tyre pressure sensor matching
process should also be performed
after replacing a spare tyre with a
road tyre containing a tyre pressure
sensor. The control indicator w and
the warning message should
extinguish at the next ignition cycle.
The sensors are matched to the tyre/
wheel positions, using a TPMS
relearn tool, in the following order:
● left front tyre
● right front tyre
● right rear tyre
● left rear tyre
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 tyre pressure sensor matching
process is as follows:
1. Apply the electrical parking brake 3 143 ; on vehicles with automatic
transmission move the selector
lever to position P.
2. Turn the ignition on 3 125.
3. Initiate the TPMS Learn Mode by simultaneously pressing p and
q on the radio remote control,
- or -
Press INFO on the Infotainment
system until a tyre learn message appears on the Info-display.
Press and hold OK.
The horn sounds twice and the left front turn signal also illuminates
as confirmation that Learn Mode
has been enabled.
4. Start with the left front tyre. 5. Place the relearn tool against the tyre sidewall, near the valve stem.
Then press the button to activate
the tyre pressure sensor. A horn
chirp confirms that the sensor
identification code has been
Vehicle care187Wheel covers
Wheel 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.
They must be fitted to the tyres
symmetrically in order to achieve a
concentric fit.
9 Warning
Damage may lead to tyre blowout.
Special snow chains are only
permitted when they are designed
with a rotating chain belt on the tyre
tread, no chain links on the wheel
inboard sides and the chains add no
more than 12 mm to the tyre tread.
For further information regarding
correct snow chain usage for the tyre
size, contact a specialised vehicle
parts dealer or snow chain
manufacture. Tyre chains are only
permitted on tyres of size
235/60 R17 and 235/55 R18.General
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit
Minor damage to the tyre tread or
sidewall 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 near the rim
cannot be repaired with the tyre repair kit.

Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel
3 187.
Make the following preparations and
observe the following information:
● Park the vehicle on a level, firm and non-slippery surface. The
front wheels must be in the
straight-ahead position.
● Apply the electrical parking brake
3 143 and engage first gear,
reverse gear or P.
● Remove the spare wheel 3 193.● Never change more than one
wheel at a time.
● Block wheel diagonally opposite the wheel to be changed, by
placing wedge blocks or
equivalent in front and behind the wheel.
● Use the jack only to change wheels in case of puncture, not
for seasonal winter or summer
tyre changes.
● Never exceed jack maximum working load (900 kg).
● If the ground on which the vehicle
is standing is soft, a solid board
(max. 1 cm thick) should be
placed under the jack.
● Do not raise the vehicle more than is necessary to change a
wheel.
● No people or animals may be in the vehicle when it is jacked-up.
● Never crawl under a jacked-up vehicle.
192Vehicle careIf this is not the case, carefully
lower the vehicle immediately and
reposition the jack. Raise the
vehicle until the wheel is just clear of the ground.
6. Unscrew wheel nuts completely and wipe clean with a cloth.

Spare wheel
Temporary spare wheel
Some vehicles are equipped with a tyre repair kit instead of a spare
wheel.
The temporary spare wheel is
designed for use on your vehicle only.
If mounting a spare wheel which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
Use of the temporary spare wheel
could affect driveability, particularly if
using winter tyres. Have the defective
tyre renewed as soon as possible and have the wheel balanced and fitted tothe vehicle.Caution
The use of a spare wheel that issmaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The temporary spare wheel is located in the load compartment below the
floor cover and is secured with a
screw-in retainer.
