SAFETY
3 - 2
Warning:
Always apply parking before leaving
driver's seat.
Note:
Each time the parking brake is applied
and ignition key is turned or left to the
ON
posi-
tion, the stoplights automatically light up.
ABS Brakes (antilock braking
system)
The purpose of the antilock braking system is to
preserve the stability and steerability of a vehicle
during braking.
On slippery roads and in emergency situations,
overbraking frequently induces wheel locking.
Antilock braking system provides maximum
braking performance while maintaining adequate
steerability on slippery roads.
Also, on smooth or slippery surfaces, the stop-
ping distance with locked wheels is greatly ex-
tended; on rough surfaces the problem is tire
abrasion.
The basis of ABS is constant monitoring of the
wheel behavior during braking. Sensors on each
wheel of front and drive axles continually monitor
the wheel speed during braking, transmitting the
information to a four-channel electronic proces-
sor which senses when a wheel is about to lock.
Modulating valves quickly adjust the brake pres-
sure (up to 5 times per second) to prevent wheel
from locking. Each wheel is thereby controlled
according to the grip available between it's tire
and the road.
In this way the vehicle is brought to a halt in the
shortest possible time, while remaining stable
and under driver's control.
Caution:
On slippery roads, motorists behind
you may not be able to brake as fast as you; so
where possible, give a prior warning by lightly
depressing brake pedal several times before
braking.
Air System Emergency
Fill Valve
The vehicle is equipped with two air system
emergency fill valves to supplement the air sys-
tem when air pressure is low and engine cannot
be operated.
The rear valve is located in engine R.H. side
compartment.
12033M
The front valve is located in the front service
compartment.
These two air system emergency fill valves are
fitted with the same valve stems as standard
tires, and can be filled by any standard external
air supply line.
The rear air system emergency fill valve will
supply air for all systems (brakes, suspension
and accessories) while the front fill valve will
supply air for accessories only.
Caution:
Air filled through these points will pass
through the standard air filtering system provided
by Prévost. Do not fill air through any other
points.
