5-20 Removing the Spare Tire and Tools
The jacking equipment you'll need is stored by your
vehicle's rear doors, along the passenger's side wall.
Remove your jack cover by pulling it away from the
side wall and down to release the tabs securing the top
of the cover.
Remove the wheel blocks by turning the top nut
counterclockwise. Remove the nut and washer, then pull
the wheel blocks off the bolt. Push down on the bolt and
remove the hooked end from the slot. Slide the jack
toward the front of the vehicle and lift it from the
mounting. Remove the extension and the ratchet from
the pouch.

5-22
Put the flat end of the extension on an angle through the
hole in the rear door frame, above the bumper. Be sure
the flat end connects into the hoist shaft.
Turn the ratchet counterclockwise to lower the spare tire
to the ground. Keep turning the ratchet until the spare
tire can be pulled out from under the vehicle.
When the tire has been
lowered, tilt the retainer
plate at the end of the cable
and pull it through the
wheel opening.
Pull the tire out from under the vehicle.
NOTICE:
To help avoid vehicle damage, do not drive the
vehicle before cable is restored.

6-6
While refueling, place the cap in the holder on the fuel
filler door.
To remove the cap, turn it slowly to the left
(counterclockwise). The cap has a spring in it; if you let
go of the cap too soon, it will spring back to the right.
CAUTION:
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you if you open the
fuel filler cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any ªhissº noise to stop. Then unscrew
the cap all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See ªCleaning the
Outside of Your Vehicleº in the Index.
