WARNING!
Fitting other wheel sizes to the vehicle will change
the vehicle’s handling characteristics and may
lead to an accident resulting in severe personal in-
juries, death and property damage.
Do not use retreaded/ remolded tires. This process
does not always permit previous damage to the
detected. Therefore vehicle safety cannot be
guaranteed if retreaded/remolded tires are fitted
.

A wheel could work loose. To avoid the risk of serious or
fatal injuries or vehicle damage, please bear the follow-
ing points in mind: Always replace wheel bolts that are damaged or
rusted.
Never apply oil or grease to wheel bolts. If a wheel hub thread is damaged, you must not drive the
vehicle. Consult a qualified specialist workshop. Be sure to use correct mounting bolts. Check
tightness of wheel bolts or nuts regularly and
retighten with a torque wrench, if necessary.
Tighten wheel bolts or nuts in a cross-pattern
sequence.Mounting bolts and tightening torque, see Chapter 12,
‘‘Installing a Wheel’’. After changing a wheel, the wheel bolts or nuts
must be tightened once the vehicle has been
driven for about 30 miles (50 km).If new or repainted wheels are fitted, the wheel bolts or
nuts must be retightened again after about 600 to 3,000
miles (about 1,000 to 5,000 km).
