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
186Vehicle carematched to this tyre and wheel
position. The next relevant turn
signal illuminates.
6. Proceed to the right front tyre, and
repeat the procedure in Step 5.
7. Proceed to the right rear tyre, and
repeat the procedure in Step 5.
8. Proceed to the left rear tyre, and repeat the procedure in Step 5.
The horn sounds twice to indicate
the sensor identification code has been matched, and the tyre
pressure sensor matching
process is no longer active.
9. Turn off the ignition.
10. Set all four tyres to the recommended inflation pressure
3 212.
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.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels. Ensure that the direction
of rotation of the wheels is the same
as before.
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
speedometer as well as the nominal
tyre pressure and make other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
If wheel rims of a different type are to
be installed, the wheel nuts may also
need to be changed. We recommend you consult a workshop.
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.
In vehicles with a tyre repair kit, there may not be a jack and vehicle tool kit.

To remove sealant canister, release sealant filler hose and air hose, slide
canister out of housing and unscrew hose from canister. Dispose of thecanister as prescribed by applicable
laws.
The accessory adapter supplied can
be used to pump up other items e.g. footballs, air mattresses, inflatable
dinghies etc. The adapter is located
on the underside of 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.
Vehicle care191●Do not start the engine when it is
raised on the jack.
● Clean wheel nuts and thread before mounting the wheel.9Warning
Do not grease wheel bolt, wheel
nut and wheel nut cone.
1. Pull off the wheel cover.
2. Install the wheel wrench ensuring that it locates securely and loosen
each wheel nut by one turn by
turning anticlockwise.
3. The location of front and rear jacking points is indicated by
notches on the bottom edge of the vehicle, under the doors.
4. Before positioning the jack, set it to the necessary height by
rotating the eye by hand.
Position jack at the jacking point
located nearest to the wheel concerned so that the jack claw
spans the vertical base. Ensure
the jack is positioned correctly.
The jack base must be on the
ground directly below the jacking
point in a manner that prevents it
from slipping.
5. Attach wheel wrench to eye of threaded rod and rotate wrench
clockwise to raise 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.
Do not grease the threads. Put
wheel nuts somewhere where the threads will not be soiled.

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.
Push both levers on the floor cover
towards the handle and pull up the
cover by the handle. Hang the hook
to the upper part of the tailgate
opening.

Remove the retainer by rotating it
anticlockwise and remove temporary
spare wheel from the spare wheel
well.
Only mount one temporary spare
wheel. Do not drive faster than
80 km/h. Take curves slowly. Do not
use for a long period of time.
When the temporary spare wheel is
fitted, do not take the vehicle through an automatic vehicle wash with guide
rails. The temporary spare wheel may get caught on the rails, causing
damage to the tyre, wheel and other
vehicle parts.
The use of tyre chains is not permitted
on the temporary spare wheel.

194Vehicle careDirectional tyres
Fit directional tyres such that they roll in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
The following applies to tyres fitted
opposing the rolling direction:
● Driveability may be affected. Have the defective tyre renewed
or repaired as soon as possible
and fit it instead of the spare
wheel.
● Do not drive faster than 80 km/h.
● Drive particularly carefully on wet
and snow-covered road
surfaces.9 Warning
Storing a jack, a wheel or other
equipment in the load
compartment could cause injury if they are not fixed in place
properly. During a sudden stop or
a collision, loose equipment could
cause personal injury or damage
to the vehicle.
Always store the jack and vehicle
tools in their respective storage
compartments and secure them properly.
Always place the damaged wheel
in the load compartment, secured
