CAUTION
Never use oil or grease on the bolts or nuts.
Doing so may lead to overtightening the nuts
and damaging the bolts. The nuts may loose
and the wheels may fall off, which could cause
a serious accident. If there is oil or grease on
any bolt or nut, clean it.
IN CASE OF AN EMERGENCY
8. Lower the vehicle completely and tighten the
wheel nuts.
Turn the jack handle counterclockwise to lower the
vehicle.
Use only the wheel nut wrench to tighten the nuts.
Do not use other tools or any additional leverage other
than your hands, such as a hammer, pipe or your foot.
Make sure the wrench is securely engaged over the
nut.
Tighten each nut a little at a time in the order shown.
Repeat the process until all the nuts are tight.
