or rusted.

Incorrect wheel bolts or improperly tightened
wheel bolts can cause the wheel to come off.
This could cause an accident. Make sure to
use the correct wheel bolts.

Other wheel bolts may come loose.
Do not tighten the wheel bolts when the
vehicle is raised. Otherwise, the vehicle could

bolts when remounting the original wheel
after it has been repaired.

surfaces.
To prevent damage to the
paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.

Place the emergency spare wheel on the
wheel hub and push it on.
Tighten the wheel bolts until they are
finger-tight.
