Set the vehicle to the parking brake and engage first or reverse gear or the parking lock.
Turn on the hazard warning lights and place an emergency stop sign on the road.
Block the wheels of the opposite side with stones or wooden blocks.
Insert your fingers into the holes in the wheel cover and remove it.
If the car has alloy wheels with hidden fastening, insert a screwdriver into the side recess on the cap and remove the cap.
Use a key to open the "secret" bolt for fastening the wheels, if your car has one.
Loosen the wheel mounting bolts by about a turn each.
Place the jack under the threshold of the car with the bevel facing inward at the designated place of the lower edge of the body. The jack should enter the vertical brace of the body.
On soft ground, place a board under the jack.
Raise the car.
Completely unscrew the wheel mounting bolts.
Remove the wheel, put on the spare wheel. The centering pin from the on-board tool kit can help here if you screw it into the bolt hole before installing the wheel.
Apply grease or liquid lubricant to the cone and threads of the wheel bolt.
Tighten the bolts evenly and crosswise, turning the wheel first one way and then the other so that it is perfectly centered on the hub.
Lower the vehicle and tighten the bolts (110 Nm).
Put on the cap. Pay attention to the cutout for the tire valve.
After a short drive, check that the bolts are securely seated.
Hint: If the wheel bolts cannot be screwed into the wheel hub, the cause may be a brake disc that has turned on the hub. Turn it until the holes line up.
