NOTE:
In some situations the jack may need to be
placed on its side in order to be pushed under
the vehicle. Return the jack to its correct
orientation once it is under the vehicle.
3. Place the wrench on the jack screw and turn
to the right until the jack head is properly
engaged in the appropriate location. Do not
raise the vehicle until you are sure the jack
is securely engaged.
4. Raise the vehicle by turning the jack screw to the right, using the swivel wrench. Raise
the vehicle only until the tire just clears the
surface and enough clearance is obtained
to install the compact spare tire. Minimum
tire lift provides maximum stability.
WARNING!
Being under a jacked-up vehicle is
dangerous. The vehicle could slip off the jack
and fall on you. You could be crushed. Never
get 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.

10. Place the deflated (flat) tire and compact
spare tire cover assembly in the rear cargo
area. Do not stow the deflated tire in the
compact spare tire location. Have the
full-sized tire repaired or replaced, as soon
as possible.
11. Stow the cable and wheel spacer before driving the vehicle. Reassemble the winch
handle extensions to form a “T” and fit the
winch T-handle over the drive nut. Rotate
the nut to the right until the winch
mechanism clicks at least three times.
NOTE:
Refer to the “Spare Tire Tools” section for
instructions on assembling the T-handle.
12. Stow the jack, jack handle and winch handle tools back in the stowage
compartment.
13. Check the compact spare tire pressure as soon as possible. Correct the tire pressure,
as required.Securing The Compact Spare Tire

1. Assemble the winch handle extensions to form a T-handle and fit the winch T-handle
over the drive nut. Rotate the nut to the left
until the winch mechanism stops turning
freely. This will allow enough slack in the
cable to allow you to pull the wheel spacer
out from under the vehicle.

2. Assemble the winch handle extensions to form the spare tire hook, and pull the wheel
spacer from under the vehicle. 3. Turn the compact spare tire so that the
valve stem is down, and place the tire into
the compact spare tire/cover assembly.
Slide the wheel spacer through the center of
the wheel and compact spare tire/cover
assembly, so that the two retainer tabs
snap out and engage the compact spare tire
cover on the opposite side.
WARNING!
A loose compact spare tire/cover assembly,
thrown forward in a collision or hard stop
could endanger the occupants of the vehicle.
Always stow the compact spare tire with the
cover assembly in the place provided.
CAUTION!
The winch mechanism is designed for use
with the winch T-handle only. Use of an air
wrench or other power tools is not
recommended and can damage the winch.
WARNING!
Verify that both retainer tabs of the wheel
spacer have been properly extended through
the center of the wheel and compact spare
tire/cover assembly. Failure to properly
engage both retainer tabs could result in loss
of the compact spare tire and cover
assembly, which will cause vehicle damage
and may cause loss of vehicle control and
serious personal injury.
CAUTION!
The compact spare tire/cover assembly must
be used when the compact spare tire is
stored. Failure to use this cover could
drastically reduce the life of the compact
spare tire.

4. Using the winch T-handle, rotate the drive
nut to the right until the compact spare
tire/cover assembly is drawn into place
against the underside of the vehicle.
5. Continue to rotate the nut to the right until you hear the winch mechanism click three
times. It cannot be overtightened. Check
under the vehicle to ensure the compact
spare tire/cover assembly is positioned
correctly against the underside of the
vehicle.Road Tire Installation
Vehicles Equipped With Wheel Covers

1. Mount the road tire on the axle.

2. To ease the installation process for steel wheels with wheel covers, install two lug
nuts on the mounting studs which are on
each side of the valve stem. Install the lug
nuts with the cone shaped end of the nut
toward the wheel. Lightly tighten the lug
nuts.

Tire And Wheel Cover Or Center Cap
3. Align the valve notch in the wheel cover with
the valve stem on the wheel. Install the
cover by hand, snapping the cover over the
two lug nuts. Do not use a hammer or
excessive force to install the cover.
4. Install the remaining lug nuts with the cone shaped end of the nut toward the wheel.
Lightly tighten all the lug nuts until the
wheel sits flush onto the hub and there is no
play. The nuts will have to be fully tightened
once the vehicle is lowered. Tightening an
improperly seated wheel under vehicle load
can damage the threads, cause vibration,
and undermine safety.
5. Lower the vehicle to the ground by turning the jack handle counterclockwise.
CAUTION!
The winch mechanism is designed
specifically to stow a compact spare tire only.
Do not attempt to use the winch to stow the
full size deflated tire, or any other full-size
tire, as the tire may not be held securely.
Vehicle damage may result.
1 — Valve Stem
2 — Valve Notch
3 — Wheel Lug Nut
4 — Wheel Cover
5 — Mounting Stud
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.

224IN CASE OF EMERGENCY
TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service.
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for this
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
structural members of the vehicle, not to
bumpers or associated brackets. State and
local laws regarding vehicles under tow must be
observed. If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.

Master Cylinder — Brake Fluid Level Check
The fluid level in the master cylinder should be
checked when performing underhood services,
or immediately if the “Brake System Warning
Light” indicates system failure.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up
to the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because
it may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear.
However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only manufacturer's recommended brake
fluid. Refer to “Fluids And Lubricants” in
“Technical Specifications” for further
information.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission
performance and life. Use only the
manufacturer's specified transmission fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications. It is
important to maintain the transmission fluid at
the correct level using the recommended fluid.
No chemical flushes should be used in any
transmission; only the approved lubricant
should be used.
WARNING!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri -
cants” in “Technical Specifications” for
further information. Using the wrong type of
brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory
installed hydraulic master cylinder
reservoir.
To avoid contamination from foreign matter
or moisture, use only new brake fluid or
fluid that has been in a tightly closed
container. Keep the master cylinder reser -
voir cap secured at all times. Brake fluid in
a open container absorbs moisture from
the air resulting in a lower boiling point. This
may cause it to boil unexpectedly during
hard or prolonged braking, resulting in
sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
