Tightening torques
Caution
If the vehicle is equipped with alloy
wheels, tighten the wheel bolts
manually at least for the first five
turns.
There are two different types of
wheels with two different bolts and tightening torques.
Tightening torque for alloy wheels is
100 Nm.
Tightening torque for steel wheels is
115 Nm.
Use the correct wheel bolts for the respective wheels.
Jacking positions The jacking positions shown refer to
the use of lifting arms and accessory
jacks used for changing winter /
