Trailer Sway Control (Tsc) - Cadillac XT4 Owner's Manual

Turn Signals When Towing a
Trailer
When properly connected, the trailer
indicators will illuminate to indicate
the vehicle is turning, changing lanes,
or stopping. When towing a trailer,
the arrows on the instrument cluster
will illuminate even if the trailer is not
properly connected or the bulbs are
burned out.

Trailer Sway Control (TSC)

Vehicles with StabiliTrak/Electronic
Stability Control (ESC) have a Trailer
Sway Control (TSC) feature. Trailer
sway is unintended side-to-side
motion of a trailer while towing. If the
vehicle is towing a trailer and the TSC
detects that sway is increasing, the
vehicle brakes are selectively applied
at each wheel, to help reduce
excessive trailer sway. If equipped with
the Integrated Trailer Brake Control
(ITBC) system, and the trailer has an
electric brake system, StabiliTrak/ESC
may also apply the trailer brakes.
If TSC is enabled, the Traction Control
System (TCS)/StabiliTrak/ESC warning
light will flash on the instrument
cluster. Reduce vehicle speed by
gradually removing your foot from the
accelerator. If trailer sway continues,
StabiliTrak/ESC can reduce engine
torque to help slow the vehicle. TSC
will not function if StabiliTrak/ESC is
turned off. See Traction Control/
Electronic Stability Control 0 224.
Warning
Trailer sway can result in a crash
and in serious injury or death, even
if the vehicle is equipped with TSC.
If the trailer begins to sway, reduce
vehicle speed by gradually removing
your foot from the accelerator. Then
pull over to check the trailer and
vehicle to help correct possible

causes, including an improperly or
overloaded trailer, unsecured load,
improper trailer hitch configuration,
or improperly inflated or incorrect
vehicle or trailer tyres. See Towing
Equipment 0 280 for trailer ratings
and hitch setup recommendations.
Trailer Tyres
Special Trailer (ST) tyres differ from
vehicle tyres. Trailer tyres are
designed with stiff sidewalls to help
prevent sway and to support heavy
loads. These features can make it
difficult to determine if the trailer tyre
pressures are low only based on a
visual inspection.
Always check all trailer tyre pressures
before each trip when the tyres are
cool. Low trailer tyre pressure is a
leading cause of trailer tyre blowouts.
Trailer tyres deteriorate over time. The
trailer tyre sidewall will show the
week and year the tyre was
