312 Vehicle Care
The rubber in tires ages over time.
This also applies to the spare tire,
if the vehicle has one, even if it is
never used. Multiple factors
including temperatures, loading
conditions, and inflation pressure
maintenance affect how fast aging
takes place. GM recommends that
tires, including the spare if
equipped, be replaced after six
years, regardless of tread wear. The
tire manufacture date is the last four
digits of the DOT Tire Identification
Number (TIN) which is molded into
one side of the tire sidewall. The
first two digits represent the week
(01–52) and the last two digits, the
year. For example, the third week of
the year 2010 would have a
four-digit DOT date of 0310.
Vehicle Storage
Tires age when stored normally
mounted on a parked vehicle. Park
a vehicle that will be stored for at
least a month in a cool, dry, clean
area away from direct sunlight to
slow aging. This area should be freeof grease, gasoline, or other
substances that can deteriorate
rubber.
Parking for an extended period can
cause flat spots on the tires that
may result in vibrations while
driving. When storing a vehicle for
at least a month, remove the tires or
raise the vehicle to reduce the
weight from the tires.
Buying New Tires
GM has developed and matched
specific tires for the vehicle. The
original equipment tires installed
were designed to meet General
Motors Tire Performance Criteria
Specification (TPC Spec)
system rating. When
replacement tires are needed,
GM strongly recommends
buying tires with the same TPC
Spec rating.
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of the
vehicle, including brake system
performance, ride and handling,
traction control, and tire
pressure monitoring
performance. GM's TPC Spec
number is molded onto the tire's
sidewall near the tire size. If the
tires have an all-season tread
design, the TPC Spec number
will be followed by MS for mud
and snow. See
Tire Sidewall
Labeling 0298.
GM recommends replacing worn
tires in complete sets of four.
Uniform tread depth on all tires
will help to maintain the
performance of the vehicle.
Braking and handling
performance may be adversely
affected if all the tires are not
replaced at the same time.
If proper rotation and
maintenance have been done,
all four tires should wear out at
about the same time. See Tire
Rotation 0310. However, if it is

.Whether the vehicle is ready to
be towed. Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
Caution
Use of a shield mounted in front
of the vehicle grille could restrict
airflow and cause damage to the
transmission. The repairs would
not be covered by the vehicle
warranty. If using a shield, only
use one that attaches to the
towing vehicle.
Dinghy Towing
These vehicles may be dinghy
towed from the front. These vehicles
can also be towed by placing them
on a platform trailer with all four
wheels off the ground. Also see the
information on dolly towing later in
this section.
For vehicles being dinghy towed,
the vehicle should be run at the
beginning of each day and at each RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle to be towed and secure it to the
towing vehicle.
2. Start the vehicle.
3. Shift the transmission to N (Neutral).
4. Put the vehicle into ACCESSORY Mode by
pressing ENGINE START/
STOP one time without the brake pedal applied. An amber
light will appear in the button
when in ACCESSORY Mode.
See
Ignition Positions 0192.
The chime will ring
continuously for 30 minutes.
Leave the transmission in
N (Neutral).
5. Turn off all accessories that are not needed.
It is required to charge the battery of
the towed vehicle during
recreational vehicle towing.
Caution
If the vehicle is towed without
performing each of the steps
listed under “Dinghy Towing,” the
automatic transmission and AWD
system could be damaged. Be
sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.
