– Stow and attach the replaced wheel in the spare wheel well.
– Stow the vehicle tool kit in the space provided.
– Check the tyre pressure on the spare wheel just mounted as soon as

– Have the tightening torque of the wheel bolts checked with a torque
wrench as soon as possible. The ti ghtening torque for steel and light
alloy wheels must be 120 Nm.
– Have the defective tyre repaired as soon as possible.
WARNING
It is necessary to observe the guidelines given on ⇒page 188, “New tyres and wheels” if the vehicle is subseq uently fitted with tyres which are different to those it was fitted with at the works.
Note
•If you find, when changing the wheel, that the wheel bolts are corroded and difficult to turn, the bolts must be replac ed before checking the tightening torque.
•Drive cautiously and only at a moderate speed to a workshop where the tight- ening torque can be checked.
