FILL VALVE IN ENGINE COMPARTMENT
12211
CAUTION
Air filled through the two emergency fill valves
will pass through the standard air filtering-
drying system. Do not fill air at any other
location. Do not exceed 120 psi (827 kPa).
EMERGENCY AND PARKING
BRAKES
During normal operation, if air pressure in any
brake circuit drops below 40 psi (276 kPa),
spring-loaded emergency brake will be
immediately applied at full capacity to the drive
axle wheels to stop the vehicle.
Spring-loaded parking brake is applied by pulling
up the control valve knob located on the L.H.
lateral console.
Parking brake is not designed to be used as a
service brake. For normal driving conditions, the
control valve knob must remain in the down
position.
DANGER
Always apply the parking brake before leaving
the driver's seat.
NOTE
Only use the parking brake to supplement the
service brake to stop the vehicle in emergency
conditions. The stopping distance will be
considerably longer than when using normal
service brake.
NOTE
Before releasing the parking brake by pushing
down the control valve knob, check the
pressure gauges to make sure that the brake
system air pressure is greater than or equal to
95 psi (655 kPa).
NOTE
A beep will sound if the ignition switch has
been turned off without applying the parking
brake. The same beep will sound if pressure
is still applied to the service brake pedal.
NOTE
The stoplights will automatically turn on when
the parking brake is applied and the ignition
key is turned to the ON position.
DAYTIME RUNNING LIGHTS
The inner lamps only also called high beams
illuminate automatically when the engine is
started and the parking brake is released to
serve as daytime running lights. The daytime
running lights provide added safety by making
the traveling vehicle more visible to other drivers
during the day.
The daytime running lights system turns the
headlights on when:
•
Engine is running;
•
Parking brake is released;
•
The exterior lighting switch is set to the OFF
position or pressed to the first position.
