GENERAL MAINTENANCE
(2006/01- )
1. INSPECT STEERING LINKAGE AND GEAR HOUSING
(a) Check the steering wheel free play.
(b) Check the steering linkage for looseness or
damage.
(1) Check that the tie rod ends do not have
excessive play.
(2) Check that the dust seals and boots are not
damaged.
(3) Check that the boot clamps are not loose.
(4) Check that the steering gear housing is not
damaged.
(5) Check that the connectors are properly
connected to the steering gear housing.
2. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
(1) Jack up the front of the vehicle and place
wooden blocks with a height of 180 to 200 mm
(7.09 to 7.87 in.) under the front tires.
(2) Lower the vehicle until the front coil spring has
about half its ordinary load. Place stands under
the vehicle for safety.
(3) Check that the front wheels are pointing
straight ahead. Use wheel chocks on all 4
wheels.
(4) Using a lever, pry up the end of the lower arm.
Check the amount of play.
Maximum ball joint vertical play:
0 mm (0 in.)
If there is any play, replace the ball joint.
(b) Check the dust cover for damage.
3. INSPECT DRIVE SHAFT BOOTS
(a) Check the drive shaft boots for loose clamps,
grease leakage, kinks or damage.
4. INSPECT AUTOMATIC TRANSAXLE FLUID LEVEL
(a) Visually check the transmission for fluid leakage. If
oil is leaking, find the cause and repair it.
5. INSPECT TRANSFER OIL (for 4WD)
(a) Visually check the transfer for oil leakage. If oil is
leaking, find the cause and repair it.
6. INSPECT REAR DIFFERENTIAL OIL (for 4WD)
(a) For the rear differential oil inspection, refer to the
following procedures (see page DF-3).

TIRE AND WHEEL – TIRE PRESSURE WARNING SYSTEMTW–7
TW
(b) Under the following conditions, the system may not
function properly;
• Areas, facilities or devices that use similar radio
frequencies are located in the vicinity of the
vehicle.
• Devices using similar radio frequencies are used
in the vehicle.
• Large amounts of snow or ice are stuck to the
vehicle, especially on the wheels and around the
wheel houses.
• The battery of the transmitter is depleted.
• Tires and wheels without tire pressure warning
valves and transmitters are used.
• Snow tires and tire chains are used.
• If wheels other than the specified ones are used,
the system may not function properly because
different radio waves are transmitted from the tire
pressure warning valve and transmitter.
• Depending on the tire type, the tire pressure
warning valve and transmitter may not function
properly even though the specified wheels are
used.
• The system may not function properly if it is
initialized with tire pressures which are not the
specified values.
(c) The average life of the grommet of the tire pressure
warning antenna and receiver is approximately 5
years, at which time it must be replaced. Retighten
the valve nut if the valve is leaking air, if it is less
than 5 years old, and there is no problem with the
grommets.
(d) After removing and installing the ECU or a sensor,
output a diagnosis code and check that it is a
normal code.
3. FUNCTION OF COMPONENTS
Components Function
Tire pressure warning antenna and receiver • Combined as a single unit with a disc wheel air valve, it measures
tire pressure and temperature, and transmits an ID number for
measurement value and identification
• Battery is built into valve
Tire pressure warning antenna and receiver Receives necessary signals from tire pressure warning antenna and
receiver and transmits them to tire pressure warning ECU
Tire pressure warning ECU • Receives signal from receiver and identifies it as vehicle's own
signal.
• If measurement value is equal to or lower than specified value, it
transmits a signal so that the air pressure warning light on
combination meter turns on.
Tire pressure warning light Located in the combination meter, it informs driver of lowered tire air
pressure and system failure
