Make sure the jack is located on firm ground, and engage the jack head correctly with the sill. Raise the jack until the wheel is clear of the ground.
Unscrew the wheel bolts and remove the wheel. Fit the spare wheel and screw in the bolts. Lightly tighten the bolts with the wheelbrace then lower the car to the ground.
Securely tighten the wheel bolts in a diagonal sequence then refit the wheel trim. Stow the punctured wheel and tools back in the luggage compartment or cradle (as applicable).
