Operation
ATC OFF ROAD or MUD / SNOW Switch
The optional ATC system comes equipped with one
of two switches that perform the same functions of
enabling and disabling the ATC system.
NOTE: Be sure to turn the ATC OFF ROAD or MUD /
SNOW switch off when you return to a firm surface.
The function of this switch is to allow greater engine
power and more wheel spin.
When operating on
soft road surfaces, place the OFF ROAD or MUD /
SNOW switch in the ENABLE position. The switch
indicator will flash slowly to indicate that this function
has been selected, and will flash rapidly whenever
ATC is operating to control excessive wheel spin.

WARNING
To prevent property damage, personal injury,
and / or death, vehicles equipped with Stability
Control have reduced effectiveness when pulling
double or triple trailers.
WARNING
To prevent property damage, personal injury,
and / or death, Stability Control systems are
designed to enhance overall vehicle stability
by automatically reducing vehicle speed under
certain conditions. Drivers operating a Stability
Control equipped vehicle should employ safe
driving practices and assume no additional
driving risks.
CAUTION
To prevent property damage, modification
to vehicles equipped with stability control
systems require prior approval through Navistar
or the stability control system manufacturer.
Unapproved
modifications may result in
diminished stability control performance.
The optional stability control system provides the core ABS
function as well as ATC and Roll Stability functions.
Core ABS Functions: The core ABS reduces wheel lock-up
to help drivers maintain steering control while braking. Antilock
Braking Systems (ABS) use wheel speed sensors, ABS
pressure modulator valves, and an Electronic Control Unit
(ECU) to control either four or six wheels of a vehicle. ECUs
optimize slip between the tire and the road surface by monitoring
individual wheel turning motion during braking.
Roll Stability Functions: The control system (RSP or RSC)
helps to mitigate rollovers through advanced sensing, engine
torque control, and automatic application of the vehicle brakes.
