2017.5 OPEL KARL Tyre sensors

Instruments and controls81Remaining oil life
Indicates an estimate of the oil's
useful life. The number in percentage means the current remaining oil life
and indicates when to change the
engine oil and filter 3 68.
Tyre pressure
Tyre pressures of all wheels are
displayed on this page during driving 3 158.
Tyre learn
This display allows for matching new
tire and wheel by the tyre pressure
monitoring system sensors 3 158.

158Vehicle careTemperature dependencyThe 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.
The tyre pressure value displayed in
the Driver Information Centre shows
the real tyre pressure. A cooled down
tyre will show a decreased value,
which does not indicate an air leak.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
checks the pressure of all four tyres
once a 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.
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 current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information
Centre.
The menu can be selected by
pressing the buttons on the turn
signal lever.
Press MENU to select the Vehicle
Information Menu X.
Turn the adjuster wheel to select the
tyre pressure monitoring system.

Vehicle care159System status and pressure warnings
are displayed by a message with the
corresponding tyre flashing in the
Driver Information Centre.
The system considers the tyre
temperature for the warnings.
Temperature dependency 3 157.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 75.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 189.
If
w flashes for 60-90 seconds then
illuminates continuously, there is a
fault in the system. Consult a
workshop.
After inflating, some driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure.
Vehicle messages 3 83.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w
illuminates continuously.
A temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these tyres.
Control indicator w illuminates. For
the further three tyres, the system remains operational.The use of commercially-available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
Each time the tyres are replaced, tyre
pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor; replace
valve core and sealing ring. For the
clipped sensor; replace complete
valve stem.
Vehicle loading status
Adjust tyre pressure to load condition according to the tyre information labelor tyre pressure chart 3 189, and
select the appropriate setting in the menu Tyre Load in the Driver
Information Centre, Vehicle
Information Menu 3 77 . This setting is
the reference for the tyre pressure
warnings.

160Vehicle careThe Tyre Load menu only appears if
the vehicle is in a standstill and the
parking brake is applied. On vehicles
with automatic transmission the
selector lever has to be in P.
Select:
● Lo for comfort pressure up to
3 people.
● Eco for Eco pressure up to
3 people.
● Hi for full loading.
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 exchanging the
complete wheel set and if one or more
tyre pressure sensors were replaced. The tyre pressure sensor matching
process should also be performed
after replacing a spare tyre with a
road tyre containing the tyre pressure sensor.
The malfunction light w and the
warning message or code should go
off at the next ignition cycle. The
sensors are matched to the wheel
positions, using a 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 a workshop for service. There
are two minutes to match the first
wheel position, and five minutes
overall to match all four wheelpositions. If it takes longer, the
matching process stops and must be
restarted.
The tyre pressure sensor matching
process is:
1. Apply the parking brake.
2. Turn the ignition on.
3. On vehicles with manual transmission: select neutral.
4. Use MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
6. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should be
displayed.
7. Press SET/CLR again to confirm
the selection. The horn sounds
twice to indicate that the receiver
is in relearn mode.
8. Start with the left side front wheel.
