CONTROLS AND INSTRUMENTS
Initial Adjustment of HSA
Warning of HSA → Refer to page 4-156
ADVICE
When a failure warning buzzer sounds, the HSA system is faulty. Have your
vehicle inspected at the nearest Isuzu Dealer as soon as possible.
•
If your vehicle has a manual transmission,
make an initial adjustment of the HSA in
the following cases. No initial adjustment is
necessary for a Smoother equipped model.
• The clutch is replaced or the clutch
pedal play is adjusted.
• The HSA releases the brakes much
too slowly or much too quickly when
the vehicle is started.
• The control unit of the HSA is
replaced.
Adjustment
1. Pull the parking brake lever, make
sure the gearshift lever is placed in
"N" and then start the engine.
2. Depress the clutch pedal, place the
gearshift lever into "2" (2nd gear), and
press the HSA reset switch. A buzzer
makes two short beeps repeatedly
and the HSA indicator light flashes.
3. Slowly release the clutch pedal and
when the engine speed drops 30 to
50 r/min from the idle speed, press
either the "FAST" side or "SLOW"
side of the HSA adjustment switch.
The buzzer will stop.
4. Depress the clutch pedal, place the
gearshift lever into "N" and slowly
release the clutch pedal.
