Roadside wheel change

Warning: Do not change a wheel in a situation where you risk being hit by other traffic. 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.
The spare wheel and tools are stored in the luggage compartment. Remove the cover then slacken the retaining nut and remove the jack.
Undo the wing nut and remove the retaining plate, and lift the spare wheel from the luggage compartment.
Undo the wing nut and remove the wheel chock from the inside of the rear panel. Place the chock behind or in front (as applicable) of the wheel diagonally opposite to the one to be removed.
Remove the wheelbrace from the luggage compartment lid (Saloon and Coupe) or floor (Touring).
Remove the wheel trim/hub cap (as applicable) then slacken each wheel bolt by a half turn. If anti-theft wheel bolts are fitted, they can be slackened using the adapter supplied in the tool kit attached to the boot lid.
Locate the jack head under the jacking point nearest to the wheel that is to be removed. As the jack is raised, the head must enter the rectangular recess in the jacking point.
Make sure the jack is located on firm ground then turn the jack handle clockwise until the wheel is raised 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 vehicle to the ground.
ecurely tighten the wheel bolts in the sequence shown then refit the wheel trim/hub cap (as applicable). Stow the punctured wheel and tools back in the luggage compartment and secure them in position. Note that the wheel bolts should be slackened and retightened to 100 Nm (74 Ibf ft) at the earliest possible opportunity.
