Cavity Cartridge Fuse Micro Fuse Description
CAUTION!
When installing the power distribution
center cover, it is important to ensure
the cover is properly positioned and fully
latched. Failure to do so may allow water
to get into the power distribution center
and possibly result in an electrical
system failure.
When replacing a blown fuse, it is
important to use only a fuse having the
correct amperage rating. The use of a
fuse with a rating other than indicated
may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem
in the circuit that must be corrected.
WARNING!
Do not attempt to change a tire on the
side of the vehicle close to moving
traffic. Pull far enough off the road to
avoid the danger of being hit when oper-
ating the jack or changing the wheel.
Being under a jacked-up vehicle is
dangerous. The vehicle could slip off the
jack and fall on you. You could be
crushed. Never put any part of your body
under a vehicle that is on a jack. If you
need to get under a raised vehicle, take
it to a service center where it can be
raised on a lift.
Never start or run the engine while the
vehicle is on a jack.
The jack is designed to be used as a tool
for changing tires only. The jack should
not be used to lift the vehicle for service
purposes. The vehicle should be jacked
on a firm level surface only. Avoid ice or
slippery areas.

Removing The Spare Tire
Preparations For Jacking
1. Park on a firm, level surface. Avoid ice orslippery areas.
2. Turn on the Hazard Warning flasher.
3. Apply the parking brake.
4. Shift the automatic transmission into PARK (P), or a manual transmission into
REVERSE (R).
5. Turn the ignition OFF. 6. Block both the front and rear of the wheel
diagonally opposite the jacking position.
For example, if the right front wheel is
being changed, block the left rear wheel.

NOTE:
Passengers should not remain in the vehicle
when the vehicle is being lifted or raised.
WARNING!
Do not attempt to change a tire on the side
of the vehicle close to moving traffic. Pull
far enough off the road to avoid being hit
when operating the jack or changing the
wheel.

Jacking Instructions
Jack Warning Label1. Remove the spare tire, jack and tools
from the stored location.
2. Loosen (but do not remove) the wheel lug nuts by turning them to the left one turn

Assembled Jack And Tools
WARNING!
Carefully follow these tire changing
warnings to help prevent personal injury or
damage to your vehicle:
Always park on a firm, level surface as
far from the edge of the roadway as
possible before raising the vehicle.
Turn on the Hazard Warning flashers.
Block the wheel diagonally opposite the
wheel to be raised.
Apply the parking brake firmly and shift
an automatic transmission to PARK.
Never start or run the engine with the
vehicle on a jack.
Do not let anyone sit in the vehicle when
it is on a jack.
Do not get under the vehicle when it is
on a jack. If you need to get under a
raised vehicle, take it to a service center
where it can be raised on a lift.
Only use the jack in the positions indi -
cated and for lifting this vehicle during a
tire change.
If working on or near a roadway, be
extremely careful of motor traffic.
To assure that spare tires, flat or
inflated, are securely stowed, spares
must be stowed with the valve stem
facing the ground.
WARNING! (Continued) CAUTION!
Do not attempt to raise the vehicle by
jacking on locations other than those
indicated.

5. Raise the vehicle by turning the jack screw clockwise. Raise the vehicle only
until the tire just clears the surface and
enough clearance is obtained to install
the spare tire. Minimum tire lift provides
maximum stability. 6. Remove the lug nuts and wheel.
7. Mount the spare tire on the axle.
8. Install the lug nuts with the cone-shaped
end toward the wheel. Lightly tighten the
lug nuts clockwise.
9. Lower the vehicle by turning the jack screw to the counterclockwise, and
remove the jack. WARNING!
Raising the vehicle higher than necessary
can make the vehicle less stable. It could
slip off the jack and hurt someone near it.
Raise the vehicle only enough to remove
the tire.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the wheel nuts
fully until the vehicle has been lowered.
Failure to follow this warning may result in
serious injury.
