Stow the coupling ball bar in the bag
and secure by fixing the strap through the rear right lashing eye. Wrap
around twice and tighten the strap to
secure the bag.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is selectively braked until the snaking
ceases. While system is working keep
steering wheel as still as possible.
Trailer stability assist is a function of
the Electronic Stability Control 3 174.

Accessories and vehiclemodifications
We recommend the use of genuine
parts and accessories and factory approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products - even if they have a regulatory or
otherwise granted approval.
Any modification, conversion or other
changes made to standard vehicle
specifications (including, without
limitation, software modifications,
modifications of the electronic control units) may invalidate the warranty
offered by Opel. Furthermore, such
changes may affect driver assistance
systems, fuel consumption, CO 2
emissions and other emissions of the
vehicle. They may also invalidate the
vehicle operating permit.

Vehicle care249Wheels and tyres
Tyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.
All tyre sizes are permitted as winter
tyres 3 285.Tyre designations
E.g. 215/50 R 16 95 H215:Tyre width, mm50:Cross-section ratio (tyre height

Choose a tyre appropriate for the
maximum speed of this vehicle. Refer to the EEC Certificate of Conformity
provided with the vehicle or other national registration documents.
Optional equipment could reduce the
maximum speed of the vehicle.
Directional tyres
Directional tyres should be mountedso that they rotate in the correct
direction. The proper rotation
direction is indicated by a symbol (e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel.
This also applies to vehicles with tyre
pressure monitoring system.
Tyre pressure 3 285.

Vehicle care251Tyre 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 operating permit.
The current tyre pressures can be
shown in the Driver Information
Centre.
Midlevel display:
Select the Tyre pressure page under
the Vehicle Information Menu ? in
the Driver Information Centre 3 115.
Uplevel display:
Select the Tyre pressure page under
the Info Menu in the Driver
Information Centre 3 115.
System status and pressure warnings
are displayed by a message
indicating the corresponding tyre in
the Driver Information Centre.
The system considers the tyre
temperature for the warnings.
Temperature dependency 3 249.
A detected low tyre pressure
condition is indicated by the control
indicator w 3 112.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 285.
If w flashes for 60-90 seconds then
illuminates continuously, there is a
fault in the system. Consult a
workshop.

252Vehicle careAfter 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 driving, this
could be an indicator for approaching
a low tyre pressure condition. Check
tyre pressure.
Vehicle messages 3 122.
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 spare wheel or 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.
Use only original plastic valve caps to protect valve on any damage.Caution
Do not use metal valve caps as
they lead to valve oxidation and
damage.
Vehicle loading status
Adjust tyre pressure to load condition
according to the tyre information label or tyre pressure chart 3 285, and
select the appropriate setting in Tyre
Load within the Vehicle Information
Menu 3 115. This setting determines
the reference pressures for the tyre
pressure warnings.
The Tyre Load menu only appears
when the vehicle is at a standstill and the parking brake is applied. On
vehicles with automatic transmission
the selector lever must be in P.
Midlevel display:
Select the Tyre load page under the
Vehicle Information Menu ? in the
Driver Information Centre 3 115.

Vehicle care253Select● Light for comfort pressure up to

Auto learn function After changing wheels or wheel
positions the vehicle must be
stationary for approx. 20 minutes,
before the system recalculates. The
following relearn process takes up to
10 minutes of driving in a speed range
of 40 to 100 km/h. Avoid to drive
outside of this range for a longer time.
If possible, use a country road or
similar which allows continuous
driving. During relearn process $
can be displayed or pressure values
can swap in the Driver Information Centre.
Ensure the tyre loading status is set
according to the selected pressure
3 115.If problems occur during the relearn
process, a failure message is
displayed in the Driver Information
Centre. w will flash for 60 seconds
and then illuminate continuously.
If this happens, repeat learning
process. Keep your vehicle stationary for approx. 20 minutes and then drive
again for 10 minutes as described
above.
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.
