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

13.Turn the selector switch clockwise
to the air only position. Switch on
the compressor to inflate the tyre
with air only.
Note
The driving characteristic of the
repaired tyre is severely affected,
therefore have this tyre replaced.
If unusual noise is heard or the
compressor becomes hot, turn
compressor off for at least
30 minutes.
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
canister.
Replace the used sealant canister.
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.
