FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
The use of tire sealants is not recommended and may
compromise the integrity of your tires.
Spare tire information
The spare tire for your vehicle is stowed under the rear of your vehicle
(except cutaway and stripped chassis models).
To remove the spare tire:
1. Open the rear doors and remove
the thumb screw and anti-theft
bracket. If finger pressure will not
remove the thumb screw, use the
lug wrench to loosen the screw.
2. Remove the access cover from
the rubber strip behind the left
door.
3. Remove the jack handle from the
right side compartment and insert
the tip of the jack handle through
the access hole and into the tube.
4. Turn the jack handle
counterclockwise until the cable is
slack and the tire can be slid from
under the vehicle.
5. Remove the retainer from the
spare tire.
To stow the cable retainer with the spare removed, turn the jack handle
clockwise until all slack is removed.
