ON-VEHICLE INSPECTION
1. CHECK THE FLUID LEVEL
HINT:
Drive the vehicle so that the engine and transaxle are at normal
operating temperature.
Fluid temperature: 70 - 80 °C (158 - 176 °F)
(a) Park the vehicle on a level surface and set the parking
brake.
(b) With the engine idling and the brake pedal depressed,
shift the shift lever into all positions from P to L position,
and return to P position.
(c) take out the dipstick and wipe it clean.
(d) Put it back fully into the pipe.
(e) take it out and check that the fluid level is in the HOT posi-
tion.
If there are leaks, it is necessary to repair or replace O-rings,
FIPGs, oil seals, plugs and/or other parts.
