The tow truck connector provides electrical
supply from the tow truck to the rear clearance
lights, the rear flasher lights, the tail lights and the
stop lights.
CAUTION
Air filled through the emergency fill valves must
not exceed 144 psi.
EMERGENCY AND PARKING BRAKES
During normal operation, if air pressure in any
brake circuit drops below 60 psi (414 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 depressed.
WARNING
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 gages to make sure that the brake
system air pressure is greater than or equal to
95 psi (655 kPa).
NOTE
The alarm will sound if the ignition switch has
been turned to OFF without applying the
parking brake. The same beep will sound if
pressure is still applied to the service brake
pedal.
NOTE
The stop lights automatically turn on when the
parking brake is applied and the engine is
running.
LOOSEWHEELNUT INDICATORS
All vehicle wheels are equipped with loose wheel
nut indicators that can help identify a loose wheel
nut with a simple visual inspection.
When the wheel nuts are torqued to spec, the
indicators are placed on the wheel nuts in a
uniform pattern (clockwise orientation).
If a nut loosens, its corresponding indicator will
become out of sequence (turned counter-
clockwise). this out-of-sequence indicator will be
visible during the walk around inspection.
