TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new
wheel position after rotating the
wheels 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
wheel with a road wheel 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 wheel positions, using a TPMS 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 signal
light at the current active position is
illuminated until sensor is matched.
Consult your workshop for service or
to purchase a relearn tool. There are
two minutes to match the first wheel position, and five minutes overall tomatch all four 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.
2. Turn the ignition on.
3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission automated: move
and hold the selector lever for
five seconds in position N until P
is displayed in the DIC. P
indicates that the sensor
matching process of the TPMS
can be started.
4. Use the MENU button on the turn
signal lever to select the Vehicle
Menu in the DIC.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.

6. Press the SET/CLR button to
begin the sensor matching process. A message requesting
acceptance of the process should
display.
7. Press the SET/CLR button again
to confirm the selection. The horn sounds twice to signal 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
the TPMS 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 the sensoridentification code has been
matched to the left side rear
wheel, and the TPMS 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matching process is no longer
active.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 pressure
label.
15. Ensure the tyre loading status is set according selected pressure
3 93.
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 DIC 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).
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.

Vehicle care205
Tyres age, even if they are not used.
We recommend tyre replacement
every six 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 to make other
vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.Caution
When converting to wheels with 14'', the ground clearance will be
reduced. This must be considered when passing over obstacles.
9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Wheel 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.
Steel wheels: When using locking
wheel nuts don't attach wheel covers.
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.

General information Notice
The driving characteristics of the
repaired tyre are 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.
The built-in safety valve opens at a
pressure of seven bar (102 psi).
Note the expiry date of the kit. After
this date its sealing capability is no
longer guaranteed. Pay attention to
storage information on sealant
bottle.
Replace the used sealant bottle. Dispose of the bottle as prescribed
by applicable laws.
The compressor and sealant can be used from approx. -30 °C.
The adapters supplied can be used
to pump up other items e.g.
footballs, air mattresses, inflatable
dinghies etc. They are located on the
underside of the compressor. To
remove, screw on compressor air hose and withdraw adapter.
Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 206.Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-skid surface. The front wheels
must be in the straight-ahead
position.
■ Apply the parking brake and engage first gear, reverse gear or
P .
■ Remove the spare wheel 3 214.
■ Never change more than one wheel
at once.
■ Use the jack only to change wheels
in case of puncture, not for
seasonal winter or summer tyre
change.
■ The jack is maintenance-free.
■ If the ground on which the vehicle is standing is soft, a solid board
(max. 1 cm thick) should be placed
under the jack.
■ Take heavy objects out of the vehicle before jacking up.
■ No people or animals may be in the
vehicle when it is jacked-up.

Vehicle care213
3. Ensure the jack is correctlypositioned under the relevant
vehicle jacking point.
4. Set the jack to the necessary height. Position it directly below
the jacking point in a manner that
prevents it from slipping.
Attach jack handle and with the
jack correctly aligned rotate handle until wheel is clear of theground.
5. Unscrew the wheel bolts.
6. Change the wheel. Spare wheel 3 214.
7. Screw on the wheel bolts.
8. Lower vehicle.
9. Install the wheel wrench ensuring that it locates securely and tighten
each bolt in a crosswise
sequence. Tightening torque is
110 Nm.
10. Align the valve hole in the wheel cover of the steel wheel with the
tyre valve before installing.
Install wheel bolt caps or center
cap on alloy wheel.
11. Install vehicle jacking point cover.
12. Stow the replaced wheel 3 214,
the vehicle tools 3 198 and the
key adapter 3 56.
13. Check the tyre pressure of the installed tyre and the wheel bolttorque as soon as possible.
Have the defective tyre renewed or
repaired as soon as possible.

220Vehicle care
Do not clean the engine compartmentwith a steam-jet or high-pressure jet
cleaner.
Thoroughly rinse and leather-off the
vehicle. Rinse leather frequently. Use
separate leathers for painted and
glass surfaces: remnants of wax on
the windows will impair vision.
Exterior lights Headlight and other light covers aremade of plastic. Do not use any
abrasive or caustic agents, do not use
an ice scraper, and do not clean them dry.
Polishing and waxing
Wax painted parts of the vehicle
regularly (at the latest when water no longer beads). Otherwise, the
paintwork will dry out.
Polishing is necessary only if the paint
has become dull or if solid deposits
have become attached to it.
Paintwork polish with silicone forms a
protective film, making waxing
unnecessary.Unpainted plastic body parts must not be treated with wax or polishing
agents.
Matt filmed body parts or decor tapes
must not be polished, to avoid
gleaming. Do not use hot wax
programmes in automatic car washes if the vehicle is equipped with these
parts.
Matt painted decor parts, e.g. mirror
housing cover, must not be polished.
Otherwise these parts would become agleam or the colour would be
dissolved.
Windows and windscreen wiper blades
Use a soft lint-free cloth or chamois
leather together with window cleaner
and insect remover.
When cleaning the rear window from
inside, always wipe in parallel to the
heating element to prevent damage.
For mechanical removal of ice, use a
sharp-edged ice scraper. Press the
scraper firmly against the glass so
that no dirt can get under it and
scratch the glass.Clean smearing wiper blades with a
soft cloth and window cleaner.
Remove dirt residues from smearing
wiper blades by using a soft cloth and window cleaner. Also make sure to
remove any residues such as wax,
insect residues and similar from the
window.
Ice residues, pollution and continuous
wiping on dry windows will damage or even destroy the wiper blades.
Sunroof
Never clean with solvents or abrasive
agents, fuels, aggressive media
(e.g. paint cleaner, acetone-
containing solutions etc.), acidic or
highly alkaline media or abrasive
pads. Do not apply wax or polishing
agents to the sunroof.
Wheels and tyres Do not use high-pressure jet
cleaners.
Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
