84StorageLoading information
■ Heavy objects in the loadcompartment should be placedagainst the seat backrests. Ensure
the backrests are securely
engaged. If objects can be stacked, the heavier objects should be
placed at the bottom.
■ Secure objects with lashing straps attached to lashing eyes 3 75.
■ Secure loose objects in load compartment to prevent sliding.
■ When transporting objects in theload compartment, the backrests of
the rear seats must not be angled
forward.
■ Do not allow the load to protrude above the upper edge of the
backrests.
■ Do not place any objects on the load compartment cover or theinstrument panel.
■ The load must not obstruct the operation of the pedals, parking
brake and gear selector, or hinder
the freedom of movement of the
driver. Do not place any unsecured objects in the interior.
■ Do not drive with an open load compartment.
■ Station wagon: fit safety net when objects are being transported in theload compartment. Close load
compartment cover.
■ Astra TwinTop: pay attention to maximum loading height with roof
open. Do not place objects on top
of or next to the load compartmentblind, on the cover of the
deployable anti-roll bars or behind
the rear head restraints.
■ The payload is the difference between the permitted gross
vehicle weight (see identification
plate 3 212) and the EC kerb
weight.
To calculate the EC kerb weight,
enter the data for your vehicle in the
Weights table at the front of this
manual.
The EC kerb weight includes
weights for the driver (68 kg),
luggage (7 kg) and all fluids (tank
90 % full).
Optional equipment and
accessories increase the kerb
weight.
■ Driving with a roof load increases the sensitivity of the vehicle to
cross-winds and has a detrimental
effect on vehicle handling due to
the vehicle’s higher centre of
gravity. Distribute the load evenly
and secure it properly with retaining
straps. Adjust the tyre pressure and vehicle speed according to the load

conditions. Check and retighten thestraps frequently.
Do not drive faster than 120 km/h. The permissible roof load is 75 kg and 100 kg for Station wagon with
roof railing. The roof load is the
combined weight of the roof rack
and the load.

voltage is too low or the system is
overloaded.■ Continuous warning buzzer during roof operation if the anti-roll bars
have been triggered.
■ Continuous warning buzzer starting
one minute before the end of the
9-minute standby time with the roof
in an intermediate position or the loading aid in a raised position.
■ Persistent warning buzzer when closing the tailgate, if the lowering
process of the electric load aid is
not complete or has been
interrupted.
Battery voltage
Low battery voltage in radio remote
control or electronic key. On vehicles
without check control, the message
InSP3 appears in the instrument
panel display. Replace the battery
3 20, 3 22.
Brake light switch
Brake light does not come on during
braking. Have the cause of the fault
remedied immediately by a
workshop.Engine cooling level
Low fluid level in engine cooling
system. Check coolant immediately

Tools
Vehicles with tyre repair set
The tool kit and tyre repair set are in
a storage compartment below the
floor cover in the load compartment.
Vehicles with spare wheel
The jack and tool kit are in a stowage
compartment in the boot below the
spare wheel. Spare wheel 3 198

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.
Wheel changing Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 193.
Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-skid surface. The front wheels
must be in the straight-ahead
position.
■ Apply the parking brake and engage first gear, reverse gear or
P .
■ Remove the spare wheel 3 198.
■ On the Astra TwinTop, the roof must be closed before the vehicle
is raised.

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.
