Wheel Nut
CAUTION
0 Three types of wheel nuts are used, one is
designed for use with steel wheels, one for
use with aluminum wheels, and one for use
with spare wheels. Do not mix different types
of wheel nuts.

Tire Repair
CAUTION
When replacing tire, take extra care not to damage
tire bead, rim-flange and bead seat.
Install tire, noting the following items
a. Install valve core and inflate to proper pressure.
Check
the locating rings of the tire to be sure
they show around the rim flanges on both sides
b. Check valves for leakage after inflating tires.
c.
Be sure to tighten valve caps firmly by hand
WARNING:
When, while tire
is being inflated, bead snaps
over safety hump,
it might break. Thus, to avoid
serious personal
injury, never stand over tire when
inflating it Never inflate to a pressure greater than
40 psi (275 kPa). If beads fail to seat at that
pressure, deflate
the tire, lubricate it again, and
then reinflate it. If the tire is overinflated, the
bead might break, possibly resulting
in serious
personal inlury.
Wheel Inspection
Check wheel rim (expecially rim flange and
bead
seat) for rust, distortion, cracks or other
damage Examine wheel rim for
lateral and radial runout,
using dial gauge

Spare Tire
This model is equipped with the Space Saver Spare
tire or the Foldable Spare tire
The spare tire
is designed for emergency use only
It
IS stored in a deflated condition
An inflator (canister or air pump) has been
provided to inflate the spare
The spare tire can be used repeatedly for
emergency situations However, the canister must
be replaced after each inflation
Be sure to obtain the proper size canister for spare
tire
size
CAUTION:
The spare tire
is restricted in driving speed up to a
maximum
of 80km/h (50MPH) for short
distances and emergency use only.
INFLATION WITH APPROVED INFLATOR
1 Before changing tire, carefully read the caution
and directions affixed on both the inflator and
the spare tire
2 Remove the uninflated spare tire and the
inflator from rear compartment
WARNING. Do not inflate at
this point.
3 Jack up front or rear of vehicle as required and
remove the damaged
tire Then mount the
uninflated spare
tire to the axle (Tighten
wheel nuts slightly
)
On aluminum wheels equipped vehicles be sure to
use spare wheel nuts in the tool bag
The wheel nuts for aluminum wheels must not be
used on the spare tire wheel to avoid the wheel
coming off the axle and causing personal injury.
4 Using Canister
(1) With tire valve at 6 o'clock position. inflate the
spare tire with the canister Place tire canister
on the
tire inflaction valve and push squarely
until
gas can be heard entering the tire It takes
about
3 minutes
WARNING:
The metal parts of the canister become extremely
cold during inflation and can cause frost bite.
Therefore, avoid contact with the metal, use a
glove or other means
of protection.

CHASSIS AND BODY MAINTENANCE
Spare Til
(2) To ensure complete emptying of the canister,
hold the canister in position for one minute
after sound stops
If temperature is below -10°C (14OF), the
canister must be warmed on
the windshield
defroster for five to ten minutes to provide
tire
inflation
b. In cold weather, the tire may not look fully
.inflated Therefore, drive slowly for the
first
mile, as the tire temperature rises the pressure
will mcrease.
a
Using Air Compressor
(1) Remove the valve cap from the spare tire and
securely connect the air pump hose in
its place
(2) Connect the power cord plug of the air pump
to the cigarette lighter socket The spare
tire
may be inflated to the recommended pressure
28 psi (200 kPa) in about 6 minutes Adjust
the
tire pressure per the tire placard with tire
pressure gauge
If the air pump operation is slow, run the engine
while the air pump is operating In this case,
remove jack with
the spare tire attached to the
axle.
WARNING:

hot.
(3) Disconnect the power cord plug from socket
Check the
tire for air leakage, and then
securely install and tighten the valve cap
5 Lower car and fully tighten wheel nuts
Do not
install the wheel cover on the spare tire
DEFLATION
1 Deflate tire by depressing button on tire
inflation valve or by removing valve core
WARN1 NG.
