10-62 Vehicle Care
Check that all wheel nuts are
properly tightened. See Wheel
Nut Torque under Capacities
and Specifications on
page 12 2.
WARNING
Rust or dirt on a wheel,
or on the parts to which it is
fastened, can make wheel
nuts become loose after a
time. The wheel could come
off and cause a crash. When
changing a wheel, remove
any rust or dirt from places
where the wheel attaches to
the vehicle. In an emergency,
a cloth or a paper towel can
be used, however, use a
scraper or wire brush to
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change
or tire rotation to prevent
corrosion or rust build-up.
Do not get grease on the flat
wheel mounting surface or
on the wheel nuts or bolts.

the tires have only 1.6 mm (1/16 in)
or less of tread remaining. See Tire
