If a tyre loses pressure the control
indicator w illuminates red. Stop
immediately and check tyre pressure.
Control indicator w 3 99.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised: Switch on the ignition,
press and hold the DDS button for
approx. 4 seconds, control indicator
w flashes three times.
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).
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.
If there is more wear at the front than
the rear, swap round front wheels and rear wheels periodically.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 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 reprogram the
speedometer and make other vehicle
modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
Vehicle care193Wheel coversWheel 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.
Remove the wheel covers if tyre
chains are to be installed.9 Warning
Use of unsuitable tyres or wheel
covers could lead to sudden
pressure loss and thereby
accidents.
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.
Tyre chains are permitted on tyres of
size 185/65 R 15, 195/60 R 15,
195/65 R 15, 205/55 R 16 and
205/50 R17.
Tyre chains are not permitted on tyres of size 225/45 R 17, 225/40 R 18,
225/40 ZR18 and 235/35 R 19 2)
.
Saloon, Station wagon, Van: tyre chains are only approved on tyres of
size 215/45 R 17 if the vehicle was
equipped with 18-inch wheels in the
factory.
The use of tyre chains is not permitted on the temporary spare wheel.
Tyre repair kit Minor damage to the tyre tread can be
repaired with the tyre repair kit.
Do not remove foreign bodies from
the tyres.
Tyre damage exceeding 4 mm or that
is near the rim cannot be repaired with the tyre repair kit.2) Just permitted with limitation steering angle.

6.Unscrew valve cap from defective
tyre.
7. Screw tyre inflation hose to valve.
8. The switch on the compressor must be set to §.
9. Connect the compressor plug to the accessory socket or cigarette
lighter socket.
To avoid discharging the battery,
we recommend running the
engine.10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is inflated.13. The prescribed tyre pressureshould be obtained within
10 minutes. Tyre pressure
3 225 . When the correct pressure
is obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for 10 minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
196Vehicle care
Drain excess tyre pressure with
the button over the pressure indicator.
Do not run the compressor longer than 10 minutes.
14. Detach the tyre repair kit. Screw the filler hose to the free
connection on the sealant bottle.
This prevents sealant leakage.
Stow the tyre repair kit in the load
compartment.
15. Remove any excess sealant using a cloth.
16. Take the label indicating maximum permitted speed from
the sealant bottle and affix in the
driver's field of view.
17. Continue driving immediately so that sealant is evenly distributed
in the tyre. After driving approx.
10 km (but no more than
10 minutes), stop and check tyre
pressure. Screw compressor air
hose directly onto tyre valve and
compressor when doing this.
If tyre pressure is more than
1.3 bar , set it to the correct value.Repeat the procedure until there
is no more loss of pressure.
If the tyre pressure has fallen
below 1.3 bar, the vehicle must
not be used. Seek the assistance
of a workshop.
18. Stow away tyre repair kit in load compartment.
Note
The driving characteristics 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.
The built-in safety valve opens at a
pressure of 7 bar.
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.

Spare wheel
Some vehicles are equipped with a
tyre repair kit instead of a spare
wheel.The spare wheel can be classified as
a temporary spare wheel depending
on the size compared to the other
mounted wheels and country
regulations.
The spare wheel has a steel rim.
Use of a spare wheel that is smaller
than the other wheels or together with winter tyres could affect driveability.
Have the defective tyre replaced as
soon as possible.
The spare wheel is in the load
compartment beneath the floor
covering. It is secured in the recess
with a wing nut.
Vehicle care205
Wheels and tyresDo 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.
Paintwork damageRectify minor paintwork damage witha touch-up pen before rust forms.
Have more extensive damage or rust
areas repaired by a workshop.
Underbody Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.Before and after winter, wash the
underbody and have the protective
wax coating checked.
Engine compartment
Areas of the engine compartment that
are painted in the same colour as the vehicle must be looked after like any
other painted surface.
It is advisable to wash the engine
compartment before and after winter
and preserve it with wax. Protect the
alternator and brake fluid reservoir
with plastic sheets before washing
the engine.
When washing the engine with a
steam-jet cleaner, do not direct the
steam jet towards components of the
antilock brake system, air
conditioning system or the belt drive
and its components.
After an engine wash, have all engine
room components preserved
thoroughly by a workshop using
protective wax.
Do not use high-pressure jet
cleaners.TwinTop
Clean all seals with a damp soft lint- free cloth. Allow to dry completely. Treat all seals, e.g. on the roof and
windscreen frame, with the special
maintenance kit (available from your
Opel Service Partner) from time to
time. Good contact between the fine
rubber lips and the sealing surfaces
prevents leaks and reduces clamping
forces.
