If a tire goes at, avoid further tire
and wheel damage by driving slowly
to a level place. Turn on the
hazard warning ashers.
{CAUTION
Changing a tire can be dangerous.
The vehicle can slip off the jack
and roll over or fall on you or other
people. You and they could be
badly injured or even killed. Find a
level place to change your tire.

3. Turn off the engine and do
not restart while the vehicle
is raised.
4. Do not allow passengers to
remain in the vehicle.
To be certain the vehicle will not
move, put blocks at the front and
rear of the tire farthest away from
the one being changed. That
would be the tire on the other
side, at the opposite end of the
vehicle.When you have a at tire, place the
wheel block at the tire diagonally

place to avoid getting dirt in
the threads.
Vehicle Service and Care 9-79

{CAUTION
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
you change a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In an
emergency, you can use a cloth or
a paper towel to do this; but be
sure to use a scraper or wire brush
later, if needed, to get all the rust
or dirt off. SeeChanging a Flat Tire
on page 9-75.10. Remove any rust or dirt from
the wheel bolts, mounting
surfaces and spare wheel.
11. Place the compact spare tire on
the wheel-mounting surface.
{CAUTION
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle’s wheel

get new original equipment wheel
nuts. Stop somewhere as soon
as you can and have the nuts
tightened with a torque wrench to
the proper torque specication.
