TwinTop
The tools for emergency operation of
the convertible hardtop are stowed in
the glove compartment.Wheels 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.
Tyres
Tyres of size 225/45 R 17 are only
permitted if the vehicle is equipped
with electronic stability program.Astra OPC "Nürburgring
Edition" with tyres 225/40 ZR 18
This model is factory-fitted with high-
performance sports tyres, size
225/40 ZR 18. These tyres are
approved for use on public roads but
have typical racing characteristics
and a correspondingly shallow tread.
The tyres provide sportily oriented
and experienced drivers with better
performance at faster speeds on dry
road surfaces but can cause the
vehicle to break away without
warning if this limit is exceeded. Avoid adopting a risky driving style because
of this improved performance. In wet conditions adapt your driving style
and speed to the shallow tread.
Winter tyres Winter tyres improve driving safety at
temperatures below 7 °C and should
therefore be fitted on all wheels.

Vehicle care189
Tyres of size 185/65 R 15,
195/60 R 15, 195/65 R 15 and
205/55 R 16 can be used as winter
tyres.
Tyres of size 205/50 R17 must only
be used as winter tyres.
Tyres of size 215/45 R 17,
225/45 R 17, 225/40 R 18 1)
,
225/40 ZR18 and 235/35 R 19 must not be used as winter tyres.
Saloon, Station wagon, Van: tyres of
size 215/45 R 17 are only approved
as winter tyres if the vehicle was equipped with 18-inch wheels in the
factory.
Winter tyres may only be used on the Astra OPC on special alloy wheels
approved by Opel.
Run-flat winter tyres may only be
used on factory approved alloy
wheels.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.Run-flat tyres
Run-flat tyres have reinforced, self-
supporting sidewalls, which ensure
that the tyres always have a certain
amount of driveability, even when
there is no pressure.
Run-flat tyres are only permitted on
vehicles with electronic stability
program and tyre pressure monitoring system or deflation detection system.Caution
Check tyre pressures regularly
even if run-flat tyres are fitted.
Depending on tyre manufacturer, run-
flat tyres can be identified from a
marking on the tyre wall. E.g.
ROF=RunonFlat for Goodyear orSSR=Self Supporting Runflat Tyre
for Continental.
Use of run-flat tyres is only permitted
in combination with factory approved
alloy wheels.
Do not use a tyre repair kit.
The ECO tyre pressure must not be
used.
Run-flat tyres must not be combined
with standard tyres.
If converting to standard tyres, note
that the vehicle is not equipped with a spare wheel or tyre repair kit.
Driving with a damaged tyre
A loss in tyre pressure is indicated by
the tyre pressure monitoring system
or the deflation detection system.
If a tyre has no pressure, continued
driving is possible
■ at a speed of max. 80 km/h
■ up to a distance of 80 km9 Warning
The vehicle will be more difficult to
steer and handle. Braking
distance will be longer.
Adapt driving style and speed to the changed conditions.
1) Astra OPC: Permitted as winter tyres without tyre chains.

192Vehicle care
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,

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 care199
The spare wheel well is not designedfor all permitted tyre sizes. If a wheel
wider than the spare must be stowed
in the spare wheel well after changing
wheels, the floor cover can be placed on the projecting wheel.
This must be taken into consideration
when the load compartment is being
loaded, particularly with the Astra
TwinTop 3 41.
Station wagon
Take adapter and hooks from the rails
in the load compartment walls. Raise
the rear lashing eyes and lift the floor cover to the vertical position so that it
rests on the roof lining. When closing,
guide the lashing eyes through the
slots in the floor cover. Vehicles with
cargo box: removal 3 75.
TwinTop
Accessing the spare wheel when the roof is open: Engage load
compartment cover on the rear
window frame and activate the
loading aid 3 77 . Raise the floor cover
in the load compartment.
Temporary spare wheel
Use of the temporary spare wheel
could affect driveability. Have the
defective tyre renewed or repaired as soon as possible.
Only mount one temporary spare
wheel. Do not drive faster than
80 km/h. Take curves slowly. Do not
use for a long period of time.
The use of the temporary spare wheel
on the rear axle is not permitted while
towing another vehicle. Therefore
mount the temporary spare wheel on
the front axle and a full-size tyre on
the rear axle.Tyre chains 3 193.
Directional tyres Fit directional tyres such that they rollin the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
The following applies to tyres fitted
opposing the rolling direction:
■ Driveability may be affected. Have the defective tyre renewed or
repaired as soon as possible.
■ Drive particularly carefully on wet and snow-covered road surfaces.
