Be sure to apply the parking brake and block the tires.

5.

Start the engine, depress the brake pedal and put the selector lever to the D position.

6.

While depressing the brake pedal, depress the accelerator pedal gradually.

7.

CAUTION:

Do not depress the accelerator pedal for 5 seconds or more during the test.

8.

Place the selector lever in the N position.

9.

Cool the CVT fluid.

Inspection

INFOID:0000000010245577

1.

Turn ON the ignition switch with the shift selector at the “P” position.

2.

Press the shift selector button with the brake pedal depressed, and confirm that the shift selector can be
moved to positions other than “P”. Also confirm that movement is not allowed from the “P” position to other
position without depressing the brake pedal.

3.

Move the shift selector and check for “excessive effort”, “sticking”, “noise” or “rattle”.

4.

Confirm that shift selector stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the shift selector is in matches the position shown
by the transaxle body.

5.

Make sure that the shift selector is moved to all the shift posi-
tions in the manner shown.

6.

When the shift selector button is pressed without applying for-
ward/backward force to the shift selector at “P”, “R”, “N”, “D”
positions, there should be no “sticking” on the shift selector but-
ton operation.

7.

The relationship between selector lever, engine starting ability,
and shift position indicator lighting should satisfy the conditions
of the following table.

8.

Confirm that the back-up lamps illuminate only when lever is placed in the “R” position. Confirm that the
back-up lamps does not illuminate when selector lever is pushed against “R” position in the “P” or “N”
position.

9.

Check that the transaxle is locked when the selector lever is in the “P” position.

10. When selector lever is set to manual shift gate, make sure that manual mode is displayed on combination

meter.
Shift selector lever to “+” and “

−

” sides, and check that set shift position changes.

Adjustment

INFOID:0000000010245578

1.
