{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. To help
prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
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 even more certain the vehicle will not
move, you should 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 your vehicle has a at tire, use the following
example as a guide to assist you in the placement
of wheel blocks.
The following information will tell you next how to
use the jack and change a tire.

Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage.
To avoid expensive brake repairs, evenly
tighten the wheel nuts in the proper sequence

falling off your vehicle. For the secondary latch
to work, the spare tire must be installed with
the valve stem pointing down. SeeStoring a Flat
