WHEELS AND TIRES
WHEELS AND TIRES
SPECIAL NOTES ABOUT WHEELS AND TIRES
1. Do not use wheels or tires other than the specified types.
2. Aluminum wheels are easily scratched. When washing them, use a soft cloth, never a wire brush. If the
vehicle is steam cleaned, do not allow boiling water to contact the wheels.
3. If alkaline compounds (such as saltwater or road salts) get on aluminum wheels, wash them as soon as
possible to prevent damage. Use only a neutral detergent.
9MUOQX-004
NOTES REGARDING TIRE REPLACEMENT
Note the following points when tires are to be removed from or mounted onto the wheels.
1. Be careful not to damage the tire bead, the rim bead, or the edge of the rim.
2. Use a wire brush, sandpaper, or cloth to clean and remove all rust and dirt from the rim edge and the
rim bead.
3. When cleaning aluminum wheels, use a soft cloth, never a wire brush or sandpaper.
4. Remove any pebbles, glass, nails, and other foreign items embedded in the tire tread.
5. Be sure the air valve is installed correctly.
6. Apply a soapy solution to the tire bead and the edge of the rim.
7. After mounting a tire onto a wheel, inflate the tire to 250-300 kPa (2.55-3.06 kg/cm2, 35.55-42.66
psi). Check to be sure that the bead is seated correctly onto the rim and that there are no air leaks. Then
reduce the pressure to the specified level.
8. If a tire iron is used to change a tire on an aluminum wheel, be sure to use a piece of rubber between
the iron lever and the wheel to avoid damage to the wheel. Work should be done on a rubber mat, not
on a hard or rough surface.

PRE-INSPECTION
1. Check the tire inflations and set to the recommended pressure, if necessary.
2. Inspect the front wheel bearing play; replace the bearing if necessary.
3. inspect the wheel and tire runout.
4. Inspect the ball joints and steering linkage for any excessive looseness.
5. The vehicle must be on level ground and have no luggage or passenger load.
6. The difference in height between the left and right sides from the center of the wheel to the fender brim
must not exceed
10mm (0.39 in).
7. Shake the vehicle to check operation of the shock absorbers.

Inspection
Brake system warning lamp
1. Disconnect the connector from the brake fluid level sensor.
2. Connect a jumper wire between “G/Y” and “6” terminal
(body ground).
3. Start the engine and check that the BRAKE warning lamp
illuminates.
Caution
l Be sure that the parking brake is fully released be-
fore checking.
4. If there is no illumination, check the fuse, bulb, and wiring
harness.
Brake fluid level sensor
Connect an ohmmeter to each terminal of the brake fluid lev-
el sensor connector.
Check for continuity when the float is moved up and down.
The sensor is good if there is continuity when the float is be-
low the “MIN” mark, and if there is no continuity when the
float is above the “MAX” mark. If the sensor does not pass
this test, replace it.
Fuel-level warning lamp
1. Disconnect the connector from the fuel tank unit.
2. Connect the connector terminal “W/R” to the body ground.
3. Start the engine and check that the FUEL warning lamp il-
luminates.
4. If there is no illumination, check the fuse, warning lamp, and
wiring harness.
Alternator warning lamp
1. Start the engine, connect the connector terminal “W/B” to
a body ground.
2. Check that the alternator warning lamp illuminates.
3. If there is no illumination, check the warning lamps, wiring
harness and alternator. Replace or repair as necessary.
Engine oil pressure warning lamp
1. Disconnect the connector from the oil pressure switch.
2. Start the engine and connect the connector terminal “Y/R”
to a body ground.
3. Check that the “OIL” warning lamp illuminates. If it does
not, replace the sender switch or repair the wiring harness
if bulb is not burnt out.

U TROUBLESHOOTING GUIDE
Case 1: Insufficient refrigerant
Measured pressure
Low-pressure side: Less than 78.5 kPa (0.8 kg/cm2, 11.4 psi)
High-pressure side: 785-883 kPa (8-9 kg/cm2, 114-128 psi)
Condition
l Outlet air from vents not cold.
l Bubbles seen in sight glass.
Step 1
1. Check for oil stains on the pipes, hoses and other parts, (Refer to illustration below.)
2. If oil staining is found at the connection of pipes or hoses, replace the O-ring; then, evacuate, charge,
and test the system.
3. If oil staining is not found, go to Step 2.
05UOUX-02
Step 2
1. Check for leakage from the following connections with a gas leak tester.
l Inlet and outlet of condenser.
l Inlet and outlet of receiver/drier.
l Inlet and outlet of compressor.
l Sight glass.
l Inlet and outlet of cooling unit.
2. If leakage is evident, go to Step 3.
3. If leakage cannot be found, evacuate, charge, and test the system. (System OK, but refrigerant leaked
gradually over time.)
Step 3
1. Check tightening torque of the connection where leak was detected.
2. If the connection is loose, tighten the connection to the specified torque; then evacuate, charge, and test
the system. --
3. If the connection is properly tightened, replace the O-ring; then evacuate, charge, and test the system.
