10-62 Vehicle Care
Triangle Shown, Without Similar
The triangle may be located
near each wheel on the vehicle's
exterior.
Notice: If a jack is used to raise
the vehicle without positioning it
correctly, the vehicle could be
damaged. When raising the
vehicle on a jack, avoid contact
with the rear axle control arms.
5. Attach the wrench to the jack,
and turn the wrench clockwise to
raise the jack head 7.6 cm (3 in).
6. Do not raise the vehicle yet. Put
the compact spare tire near you.
WARNING
Getting under a vehicle when it is
lifted on a jack is dangerous.
If the vehicle slips off the jack,
you could be badly injured or
killed. Never get under a vehicle
when it is supported only by
a jack.
WARNING
Raising the vehicle with the jack
improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle.
7. Raise the vehicle by turning the
wrench clockwise in the jack.
Raise the vehicle far enough off
the ground so that there is
enough room for the spare tire to
fit under the wheel well.
8. Remove all the wheel nuts and
the flat tire.
9. Remove the plastic spare tire
heat shield by pulling the rubber
latch. Store the plastic spare tire
heat shield. See Storing the
Spare Tire later in this section
for more information.
