–Check the tyre pressure on the spare wheel just mounted as
soon as possible.
– Have the tightening torque of the wheel bolts checked with
a torque wrench as soon as possible. The tightening 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 227,
“New tyres and wheels” if the vehicle is subsequently 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 replaced before checking the tight-
ening torque.
•Drive cautiously and only at a moderate speed to a workshop where
the tightening torque can be checked.
