Self-help, vehicle care

If the specified tyre pressure is not 

reached within 10 minutes, remove the 

tyre repair kit. Move the vehicle through 

one tyre rotation, approx. 2 metres, in 

either direction. Reconnect the tyre 

repair kit and continue the filling 

process for 10 minutes. If the specified 

tyre pressure is still not reached, the tyre 

is too badly damaged. Park the vehicle 

and contact a workshop. 

Drain excess tyre pressure with the 

button over the pressure indicator.
Do not run the compressor for more 

than 10 minutes - see "Important 

information" on page 259.

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 

luggage compartment. 

15. Wipe away any sealant spill with a 

cloth.

16. Disassemble the warning triangle 3 

and store in luggage compartment, see 

page 247.

17. The enclosed sticker shows the 

maximum permitted speed at which the 

tyre repair may be used. Apply sticker in 

the driver’s field of vision. 

18. Continue driving immediately to allow 

the sealant to distribute evenly 

throughout the tyre. Stop after approx. 

6 miles/10 km (no more than 10 

minutes) and check tyre pressure. Screw 

the compressor air hose directly onto 

the tyre valve (see Fig. 17256 T). 

If tyre pressure is more than 1.3 bar, 

adjust to the prescribed value. Repeat 

the procedure until there is no more 

pressure loss. 
If the tyre pressure has fallen below 

1.3 bar, the vehicle may no longer be 

used. Contact a workshop. 

19. Stow the tyre repair kit in the luggage 

compartment, see page 256.

Self-help, vehicle care

Important Information

The driving comfort of the repaired tyre is 

severely affected, therefore have this tyre 

replaced.
If the compressor makes abnormal noises 

or heats up greatly, switch it off for at least 

30 minutes.
The integrated safety valve opens at a 

pressure of 7 bar.
Protect the compressor from moisture and 

rain.

The sealant can only be stored for approx. 

4 years. After this time, the sealing 

properties can no longer be guaranteed. 

Heed the expiration date on the sealant 

bottle.
The sealant bottle can only be used once. 

Replace a used sealant bottle.
The compressor and sealant can be used 

from approx. -30 °C.
Dispose of a used tyre repair kit in 

accordance with applicable legislation.
The adapters supplied 3 can be used to 

inflate 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. 
When using the tyre repair set, no 

consumers may be connected to the front 

accessory socket. 

Electrical system 

Fuses 

The vehicle has two fuseboxes: one behind 

a cover on the left side of the luggage 

compartment and one in the front left of 

the engine compartment.

 Warning

Do not drive faster than 50 mph 

(80 km/h). 
Do not use the temporary spare wheel for 

a lengthy period. 
Steerability and driving behaviour may 

be impaired.

9

 Warning

Electronic ignition systems generate very 

high voltages. Do not touch the ignition 

system; high voltage can be fatal. 

260

Self-help, vehicle care

We recommend carrying a complete set of 

fuses. 
Put spare fuses in the provided location in 

the fusebox in the luggage compartment. 

Open cover, see page 262. 
Before replacing a fuse, turn off the 

respective switch and the ignition. 
A blown fuse (see figures to the right) can 

be recognised by its melted wire. Do not 

install a new fuse until the cause of the 

fault has been remedied. 

Different versions of fuses are used.

There is a fuse extractor in the luggage 

compartment fusebox to facilitate 

replacement of fuses – see Fig. 17258 T for 

an example. 

Place the fuse extractor on the various 

types of fuse from the top or side, and 

withdraw fuse. 

Only fit fuses of the specified current 

rating. Each fuse has its current rating 

written on it, in addition the ratings are 

colour coded.

Fusebox in engine compartment 

The fusebox is at the front left side of the 

engine compartment. 

To open the cover, release the catch by 

inserting a screwdriver into the opening as 

far as it will go and swivelling it to the side. 

Open the cover upwards and remove. 

Depending on the equipment version, 

there are two different fuse layouts for the 

engine compartment fusebox, handling 

different electrical circuits: 

z If the luggage compartment fusebox is 

version A - see Fig. 18504 T on page 263  

- the fuse layout in the engine 

compartment is version A – see next 

column. 

z If the luggage compartment fusebox is 

version B - see Fig. 17958 T on 

page 264 - the fuse layout in the engine 

compartment is version B - see page 267. 

The Astra TwinTop always has version B.

Bulb replacement 

Before replacing a bulb, switch ignition off 

and turn appropriate switch off. 
Only hold new bulb at base! Do not touch 

the bulb glass with bare hands, otherwise 

fingerprints on the glass evaporate. 

Residue builds up on the reflector 

eventually resulting in a dull reflector. 

Inadvertently stained bulbs may be 

cleaned with a clean lint-free cloth, using 

alcohol or white spirits. 
The replacement bulb must be in 

accordance with the data on the base of 

the defective bulb. Do not exceed wattage 

given on bulb base. 

The bulbs of the front outer lights are 

replaced through openings in the front 

wheel arches: turn appropriate wheels to 

gain access, release catch and remove 

cover. 
Headlight aiming 

We recommend that headlight adjustment 

be carried out by a workshop, who will 

have special equipment. 
On headlight adjustment, the manual 

headlight range adjustment 3 must be set 

to 0.
