WARNING Risk of injury through incor‐
rect tightening torque
The wheels could come loose if the wheel
bolts or wheel nuts are not tightened to the
prescribed tightening torque.
#
Make sure the wheel bolts or wheel
nuts are tightened to the prescribed
tightening torque.
#
If you are not sure, do not move the
vehicle. Consult a qualified specialist
workshop and have the tightening tor‐
que checked immediately.
#
Always observe the instructions and safety
notes on "Changing a wheel in the event of a
flat tyre" ( / page 348).
#
Observe the wheel nut tightening torques
(
/
page 394).
#
Have all wheels retightened after 50 km.
#
When using new or newly painted wheel rims,
have the tightening torque of the wheel nuts
checked again after driving approximately
1,000 to 5,000 km.
#
