Trailer Sway
Control (TSC)
Trailer Sway Control (TSC)
2500 and 3500 series vehicles with
StabiliTrak have a Trailer Sway
Control (TSC) feature. If the vehicle
is towing a trailer and the system
detects that the trailer is swaying,
the vehicle's brakes are applied
without the driver pressing the brake
pedal. If the vehicle is equipped with
the Integrated Trailer Brake Control
(ITBC) system, StabiliTrak may also
apply the trailer brakes. The TCS/
StabiliTrak warning light will flash on
the instrument panel cluster to notify
the driver to reduce speed. If the
trailer continues to sway, StabiliTrak
will reduce engine torque to help
slow the vehicle.
Adding non‐dealer/non‐retailer
accessories can affect the vehicle's
performance. SeeAccessories and
Modifications

Vehicles that have a tire pressure
monitoring system may give an
inaccurate low‐pressure warning
if non‐TPC Spec-rated tires
are installed on your vehicle.
Non‐TPC Spec-rated tires may
give a low‐pressure warning that
is higher or lower than the proper
warning level you would get with
TPC Spec-rated tires. SeeTire
Pressure Monitor System
on
page 10‑65.
Your vehicle's original equipment
tires are listed on the Tire and
Loading Information label. See
Vehicle Load Limits
on page 9‑23for more information about the Tire
and Loading Information label and
its location on your vehicle.
Different Size Tires and
Wheels
If you add wheels or tires that are
a different size than your original
equipment wheels and tires, this
could affect the way your vehicle
performs, including its braking,
ride and handling characteristics,
stability, and resistance to rollover.
Additionally, if your vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
{WARNING
If you add different sized wheels,
your vehicle may not provide an
acceptable level of performance
and safety if tires not
recommended for those wheels
are selected. You may increase
the chance that you will crash and
suffer serious injury. Only use GM
specific wheel and tire systems
developed for your vehicle, and
have them properly installed by
a GM certified technician.

Vehicle Data
Recording and
Privacy
Your GM vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven.
For example, your vehicle uses
computer modules to monitor and
control engine and transmission
performance, to monitor the
conditions for airbag deployment
and deploy airbags in a crash, and,
if so equipped, to provide antilock
braking to help the driver control the
vehicle. These modules may store
data to help your dealer technician
service your vehicle. Some modules
may also store data about how you
operate the vehicle, such as rate of
fuel consumption or average speed.
These modules may also retain the
owner’s personal preferences, such
as radio pre-sets, seat positions,
and temperature settings.

Customer Information 13-17
Event Data Recorders
This vehicle has an Event Data
Recorder (EDR). The main purpose
of an EDR is to record, in certain
crash or near crash-like situations,
such as an airbag deployment or
hitting a road obstacle, data that
will assist in understanding how
a vehicle's systems performed.
The EDR is designed to record data
related to vehicle dynamics and
safety systems for a short period of
time, typically 30 seconds or less.
The EDR in this vehicle is designed
to record such data as:
.How various systems in your
vehicle were operating
.Whether or not the driver and
passenger safety belts were
buckled/fastened
.How far, if at all, the driver was
pressing the accelerator and/or
brake pedal
.How fast the vehicle was
travelingThis data can help provide a better
understanding of the circumstances
in which crashes and injuries occur.
Important:
EDR data is recorded
by your vehicle only if a non-trivial
crash situation occurs; no data is
recorded by the EDR under normal
driving conditions and no personal
data (e.g., name, gender, age,
and crash location) is recorded.
However, other parties, such as
law enforcement, could combine
the EDR data with the type of
personally identifying data
routinely acquired during a
crash investigation.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is
needed. In addition to the vehicle
manufacturer, other parties, such
as law enforcement, that have the
special equipment, can read the
information if they have access to
the vehicle or the EDR. GM will not access this data or
share it with others except: with
the consent of the vehicle owner
or, if the vehicle is leased, with the
consent of the lessee; in response
to an official request by police or
similar government office; as part of
GM's defense of litigation through
the discovery process; or, as
required by law. Data that GM
collects or receives may also be
used for GM research needs or may
be made available to others for
research purposes, where a need is
shown and the data is not tied to a
specific vehicle or vehicle owner.
