1. CONDITIONS IN WHICH THE HILL HOLDER OPERATES

The hill holder operates only when the clutch and brake pedals are depressed with the vehicle

stopped on an uphill road.

In this condition, the PHV's ball blocks the fluid passage back to the master cylinder and, therefore,

the hydraulic pressure in the wheel cylinder circuits is maintained even after the brake pedal has

been released as long as the clutch pedal is held depressed.

2. CONDITIONS IN WHICH THE HILL HOLDER DOES NOT OPERATE

The hill holder does not operate in the following conditions:

During acceleration and constant speed driving on an uphill road

Since driver does not depress the clutch pedal during acceleration or driving at a constant speed,

the pushrod keeps the ball away from the seat. The hill holder cannot maintain the pressure in the

wheel cylinder circuits when the brake pedal is released.
