Driving and Operating

9-71

Operating the vehicle in Tow/Haul
when lightly loaded or with no trailer
at all will not cause damage.
However, there is no benefit to the
selection of Tow/Haul when the
vehicle is unloaded. Such a
selection when unloaded may result
in unpleasant engine and
transmission driving characteristics
and reduced fuel economy. Tow/
Haul is recommended only when
pulling a heavy trailer or a large or
heavy load.

Integrated Trailer Brake
Control System

The vehicle may have an Integrated
Trailer Brake Control (ITBC) system
for electric trailer brakes.

This symbol is located on the Trailer
Brake Control Panel on vehicles
with an Integrated Trailer Brake
Control System. The power output
to the trailer brakes is based on the
amount of brake pressure being
applied by the vehicle

’

s brake

system. This available power output
to the trailer brakes can be adjusted
to a wide range of trailering
situations.

The ITBC system is integrated with
the vehicle

’

s brake, anti-lock brake

and StabiliTrak systems. In trailering
conditions that cause the vehicle

’

anti-lock brake or StabiliTrak
systems to activate, power sent to
the trailer's brakes will be
automatically adjusted to minimize
trailer wheel lock-up. This does not
imply that the trailer has the
StabiliTrak system.

The vehicle may have a Trailer
Sway Control (TSC) feature. See

Trailer Sway Control (TSC) on
page 9-76

The vehicle may have a Hill Start
Assist (HSA) feature. See

Hill Start

Assist (HSA) on page 9-41

If the vehicle

’

s brake, anti-lock

brake or StabiliTrak systems are not
functioning properly, the ITBC
system may not be fully functional
or may not function at all. Make sure
all of these systems are fully
operational to ensure full
functionality of the ITBC system.

The ITBC system is powered
through the vehicle's electrical
system. Turning the ignition off will
also turn off the ITBC system. The
ITBC system is fully functional only
when the ignition is in ON or
in RUN.

The ITBC system can only be used
with trailers with electric brakes.
