CAUTION
• If the warning light and warning buzzer come on while the exhaust brake is
being used, immediately pull off to a safe place well clear of traffic and take the
following actions.
- With the engine still running, turn off the exhaust brake switch. A problem in
the exhaust brake system will be confirmed if the warning light goes out in
several seconds.
- If the warning light does not go out, the problem will be in the brake booster
for the foot (main) brake.
Have your vehicle inspected at the nearest Isuzu Dealer as soon as possible.
• This light should come on to provide a bulb check when the engine control
switch is turned to the "ON" position. It should go out when the engine has
started. If the light does not come on when the engine control switch is turned
to "ON", it could indicate a burned out bulb or a blown fuse. Have the system
repaired if the light does not come on during this check.

CONTROLS AND INSTRUMENTS
Exhaust Brake Switch
ABS Warning Light
This warning light should come on when
the starter switch is turned to the "ON"
position, and then should go out after
approximately 2 seconds.
This warning light comes on together with
the brake system warning light whenever
there is a problem in the anti-lock brake
system (ABS). In this case, the ABS stops
working but the brakes still function as
ordinary service brakes.
