Some of the details shown here will vary according to model. For instance, the location of the spare wheel and jack is not the same on all cars. However, the basic principles apply to all vehicles.
Do not change a wheel in a situation where you risk being hit by another vehicle. On busy roads, try to stop in a lay-by or a gateway. Be wary of passing traffic while changing the wheel – it is easy to become distracted by the job in hand.
- When a puncture occurs, stop as soon as it is safe to do so.
- Park on firm level ground, if possible, and well out of the way of other traffic.
- Use hazard warning lights if necessary.
- If you have one, use a warning triangle to alert other drivers of your presence.
- Apply the handbrake and engage first or reverse gear (or Park on models with automatic transmission).
- Chock the wheel diagonally opposite the one being removed – a couple of large stones will do for this.
- If the ground is soft, use a flat piece of wood to spread the load under the jack.
On Astra models the jack and wheel brace are stowed under the spare wheel beneath the luggage compartment floor. On Zafira models they are beneath a cover at the rear of the luggage compartment floor.
The spare wheel is beneath a cover in the luggage compartment on Astra models. Raise the cover, remove the screw and lift out the spare wheel. Place it beneath the sill as a precaution against the jack failing. On Zafira models, the spare wheel is under the rear of the vehicle. Lift the rear of the luggage compartment floor, and slacken the bolt in the floor, using the wheelbrace. Unhook the catch, lower the spare, and detach the cable. The spare can now be lifted out.
On models with steel wheels, use the special tool to pull the wheel trim from the wheel. On models with alloy wheels, use the screwdriver provided inserted at the wheel bolt holes, to prise off the trim. Where an anti-theft device is fitted, use the tool provided to remove the trim. Loosen each wheel bolt by half a turn.
All models have depressions in the sill vertical web, which indicate the points at which the jack head is to be attached. On Astra models, the depressions are concealed by flaps in the outer sill bodywork. Prise out the flaps to access the jacking points. Position the jack head under the jacking point and make sure that the slot in the head engages correctly with the vertical web of the sill. Turn the handle until the base of the jack touches the ground then make sure that the base is located directly below the sill. Raise the vehicle until the wheel is clear of the ground. If the tyre is flat make sure that the vehicle is raised sufficiently to allow the spare wheel to be fitted.
Remove the bolts and lift the wheel from the vehicle. Place it beneath the sill in place of the spare as a precaution against the jack failing. Fit the spare wheel and tighten the bolts moderately with the wheel brace.
Lower the vehicle to the ground, then finally tighten the wheel bolts in a diagonal sequence. Refit the wheel trim. Note that the wheel bolts should be tightened to 110 Nm (81 Ibf ft) at the earliest opportunity.
- Remove the wheel chocks.
- Stow the jack and tools in the correct locations in the car.
- Check the tyre pressure on the wheel just fitted. If it is low, or if you don’t have a pressure gauge with you, drive slowly to the nearest garage and inflate the tyre to the right pressure.
- Have the damaged tyre or wheel repaired as soon as possible.
