Operation
Brake Demand Sensors: The stability control system was
designed to supplement the driver's actions. By directly
measuring driver brake demand, the system can transition
seamlessly between driver-intended and system-intended
braking pressure. For example, if during a certain maneuver,
the system calculates 40 psi (276 kPa) is needed and the driver
is only applying 20 psi (138 kPa), the system compensates
automatically to deliver the needed 40 psi (276 kPa).
If,
however, during the same maneuver, the driver steps on the
brake pedal quickly to apply a higher [above 40 psi (276 kPa)]
braking level, the driver’s braking input overrides the temporary
change made by the system.
ABS / Stability System Interaction: With the ABS-based
stability control system, the ABS system is given priority at the
wheel ends to manage wheel slip for optimal braking. The ABS
system functions similarly whether the stability system or the
driver applies the brakes.
International ® Ride Optimized Suspension (IROS)
(If Equipped)
CAUTION
To prevent property damage, do not operate a
vehicle without air in the suspension springs.
Operating the vehicle without air in the air
suspension springs will damage the suspension,
degrade
ride performance and may cause
transmission damage.
The suspension system automatically adjusts to different loads
to maintain a constant frame height. The system allows for
ease of vehicle loading and provides improved vehicle ride and
increased driver comfort. The system is completely automatic.
Automatic Transmission Operation
Standard Allison 1000 PTS Transmission
WARNING
To prevent personal injury and / or death, or
damage to property, hold the brake pedal down
while you move the gearshift from position
to
position to prevent unexpected vehicle
movement.
WARNING
To prevent personal injury and / or death, or
damage to property, check to see that area behind
vehicle is clear of people, animals, and objects
before backing up.
Use a spotter whenever
possible and always keep that person in sight. If
so desired, backup alarms are available through
your IC Bus
® dealer. However, they are never a
substitute for the above procedures.
NOTE: For complete transmission operation, refer also to
separate Allison Transmission Operation Manual.
