MAINTENANCE
503
Accelerator pedal
Check
the pedal for smooth operation and uneven pedal ef fort
or catching.
Brake pedal
Check the pedal for smooth operation and the proper
clearance and free play. Check the brake booster function.
Brakes
In a safe place, check that the brakes do not pull to one side
when applied.
Parking brake
Check that the pedal has the proper travel and that, on a safe
incline, your vehicle is held securely with only the parking
brake applied.
Automatic transmission ”Park” mechanism
On a safe incline, check that your vehicle is held securely with
the selector lever in ”P” position and all brakes released.
Vehicle exterior
Items listed below should be performed from time to time,
unless otherwise specified.
Wheel nuts
When checking the tires, make sure to check the nuts for
looseness. Tighten them if necessary. Fluid leaks
Check
underneath for leaking fuel, oil, water or other fluid after
the vehicle has been parked for a while. If you smell fuel fumes
or notice any leak, have the cause found and corrected
immediately.
Doors and engine hood
Check that all doors, including trunk lid, operate smoothly and
all latches lock securely. Make sure the engine hood
secondary latch secures the hood when the primary latch is
released.
Tire inflation pressure
Check the tire inflation pressure with a gauge every two
weeks, or at least once a month and adjust as shown on
the tire and loading information label. See page 548 for
additional information.
Tire surface
Check the tires carefully for cuts, damage or excessive
wear. See page 563 for additional information.

automatic transmission fluid, use only “Toyota Genuine ATF
Type WS” ( ATF JWS3324 or NWS9638) to aid in assuring
optimum transmission performance.NOTICE
Using automatic transmission fluid other than “Toyota
Genuine ATF T ype WS” may cause deterioration in shift
quality, locking up of your transmission accompanied
by vibration, and ultimately damage the automatic
transmission of your vehicle.
