PART 8: MAINTENANCE AND SERVICE CAB HEATER-AIR CONDITIONER
(R05/10) Y53-6032 – 215 –
WARNING!
Although the brakes will continue to
operate with a malfunction in either circuit, the
vehicle should not be operated until the system
is repaired, and both braking circuits, including
all pneumatic and mechanical components, are
working properly. Failure to do so may result in
death or personal injury.
CAUTION: Do not attempt to recycle the anti-
lock system until the vehicle has been
brought to a full stop.
NOTE: If one wheel on any driven axle continues
to slip or spin for approximately 4 seconds, this
will cause the anti-lock controller for that axle to
go into the fail-safe mode, and the warning light
will give a shutdown signal. In this case, the anti-
lock system can be turned back on, and the warn-
ing light extinguished, by turning the key switch
OFF and ON, after the vehicle has been brought
to a full stop. When the key switch is turned back
on, the warning light will illuminate and remain on
for 3 to 5 seconds. This is a built-in function test of
the warning light.
Cab Heater-Air Conditioner
The combination heater-air conditioner provides comfort
for those in the cab through accurate control of the cab
environment in all weather conditions. Regular attention
will help you keep your unit running well.
NOTES:Keep the engine exhaust system and the
vehicle’s cab/sleeper ventilation system properly
maintained. It is recommended that the vehicle’s
exhaust system and cab/sleeper be inspected
• by a competent technician every 15,000 miles
• whenever a change is noticed in the sound of
the exhaust system
• whenever the exhaust system, underbody, cab
or sleeper is damaged
