BRAKE
2. HILL HOLDER
CAUTION:
• Description in parentheses is a characteristic of hill holder and does not indicate abnormality.
Depressing force required for clutch pedal equipped to hill holder specifications is 20 to 29 N (2 to 3
kgf, 4 to 7 lb) larger than the conventional specifications, which does not constitute abnormality.
• When vehicle cannot travel (brake cannot be released) because return spring is broken, remove
adjust nut, disconnect clutch and PHV, and then return PHV lever to release the brake. (Be sure to ap-
ply the parking brake before starting this operation.)
• The hill holder may not be activated on a slope of an extremely small inclination.
1. Counterforce of
clutch pedal is too
strong.
2. Vehicle does not
stop on uphill road of
3° ° ° ° or higher
inclination.
3. Shock is felt when
starting.
4. Vehicle slips down
when starting.
5. Vehicle cannot start
after stoppage.
6. Abnormal sound is
generated upon
releasing brake pedal
when stopping.
7. Abnormal sound is
generated when
operating clutch
pedal.
