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 care195●A discharged battery can already
freeze at a temperature of 0 °C.
Defrost the frozen battery before
connecting jump leads.
● Wear eye protection and protective clothing when
handling a battery.
● Use a booster battery with the same voltage (12 Volts). Its
capacity (Ah) must not be much less than that of the discharged
battery.
● Use jump leads with insulated terminals and a cross section of
at least 16 mm 2
(25 mm 2
for
diesel engines).
● Do not disconnect the discharged
battery from the vehicle.
● Switch off all unnecessary electrical consumers. The
Infotainment system may be
damaged if switched on while jump starting.
● Do not lean over the battery during jump starting.
● Do not allow the terminals of one
lead to touch those of the other
lead.● The vehicles must not come into contact with each other during
the jump starting process.
● Apply the electrical parking brake
3 143, transmission in neutral,
automatic transmission in P.
● Open the positive terminal protection caps of both batteries.
Lead connection order:
1. Connect the red lead to the positive terminal 1 of the booster
battery.
2. Connect the other end of the red lead to the positive terminal 2 of
the discharged battery.
3. Connect the black lead to the negative terminal 3 of the booster
battery.
4. Connect the other end of the black
lead to a vehicle grounding point,
such as the engine block 4 or an
engine mounting bolt. Connect as far away from the discharged
battery as possible, however at
least 60 cm.
Route the leads so that they cannot
catch on rotating parts in the engine
compartment.
To start the engine: 1. Start the engine of the vehicle providing the jump start.
2. After 5 minutes, start the other engine. Start attempts should be
made for no longer than
15 seconds at an interval of
1 minute.
3. Allow both engines to idle for approx. 3 minutes with the leads
connected.
4. Switch on electrical consumers (e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
