Wheel bolts
Wheel bol ts mus t alwa ys be tigh tened to the co rrect
torque .
The design of wheel bolts is matched to the factory installed rims. If
differe nt rims a re fitte d, the correc t wheel bolt s wi th the r ig ht length
and co rrectly s haped bolt heads must be used. Th is ensures that
w heels are fitte d se cu rely and that the br ake system fun ctions
correctly .
In certain circumstances, yo u may not use wheel bolts from a
different veh icle -even if it is the same model~
page 346.
& WARNING
Improperly tightened or ma intained wheel bolts can become
loose causing los s of control, a collision and seriou s per sonal
injury .
• Always keep the wheel bolts and the thread s in the wheel hub s
clean so the wheel bolts can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled , even
if tightened to the specified torque.
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle .
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss . If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving . If the tightening torque i s too h igh, the wheel
bolts and threads can be damaged and the wheel can become
loose .
