DIC Warnings and Messages
These messages will appear if there is a problem
sensed in one of your vehicle’s systems. Vehicles that
are rst sold in Canada will have a number after
each message. This number helps to identify the
problem. You must then press INFO or INFO RESET to
clear the display screen for further use. However, be

DIC Vehicle Personalization
Your vehicle is equipped with personalization capabilities
that allows you to program certain features to a
preferred setting for up to two people. The number of
programmable features varies depending upon
which model of the vehicle is purchased. On all vehicles,
features such as climate control settings, radio preset
settings, exterior lighting at unlock, remote lock and
unlock conrmation, and automatic door locks
have already been programmed for your convenience.
Some vehicles are equipped with additional features that
can be programmed including the seat position,
steering column position (if equipped) and outside mirror
position. The navigation screen preferences (if
equipped) will remain at the last set position.
If your vehicle is equipped with the ability to program
additional personalization features, the driver’s
preferences are recalled by pressing the unlock button
on the remote keyless entry transmitter or by pressing
the appropriate memory button, 1 or 2, located on
the driver’s door. Certain features can be programmed
not to recall until the key is placed in the ignition.
To change feature preferences you must use one of the
following procedures.
Entering Feature Programming
To enter feature programming mode, do the following:
1. Turn the ignition to ON, making sure the vehicle is in
PARK (P).
2. If your vehicle has memory settings, press the
appropriate memory button, 1 or 2, located on
the driver’s door panel. The DIC display will show

Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.)
The grades are molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12 inches
(25 to 30 cm), or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specied government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specied government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
