You may notice, during cooler weather conditions,
that the tire pressure monitor light, located on
the instrument panel cluster, and the CHECK TIRE
PRESSURE message will appear when the
vehicle is rst started and then turn off as you
start to drive the vehicle. This could be an early
indicator that the tire pressures are getting low and
need to be in ated to the proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and in ated to
the in ation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
in ation pressure label. (If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire in ation pressure label, you
should determine the proper tire in ation
pressure for those tires.)As an added safety
feature, your vehicle
has been equipped with
a tire pressure
monitoring system
(TPMS) that illuminates
a low tire pressure
telltale when one
or more of your tires is
signi cantly
under-in ated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and in ate them to the
proper pressure. Driving on a signi cantly
under-in ated tire causes the tire to overheat and
can lead to tire failure. Under-in ation also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-in ation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.

Resetting the TPMS Identi cation Codes
Each TPMS sensor has a unique identi cation
code. Any time you rotate your vehicle’s tires or
replace one or more of the TPMS sensors,
the identi cation codes will need to be matched to
the new tire/wheel position. The sensors are
matched to the tire/wheel positions in the following
order: driver’s side front tire, passengers side
front tire, passengers side rear tire, and driver’s
side rear tire using a TPMS diagnostic tool.
See your GM dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. If increasing the tire’s
air pressure, do not exceed the maximum in ation
pressure indicated on the tire’s sidewall.
You will have two minutes to match the rst
tire/wheel position, and ve minutes overall to
match all four tire/wheel positions. If it takes longer
than two minutes, to match the rst tire and
wheel, or more than ve minutes to match all four
tire and wheel positions the matching process
stops and you will need to start over.The TPMS sensor matching process is outlined
below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Using the DIC, press the vehicle information
button until the RELEARN TIRE POSITIONS
message displays. If your vehicle does not
have the DIC buttons, press the trip odometer
reset stem located on the instrument panel
cluster until the RELEARN TIRE POSITIONS
message displays.
4. If your vehicle has the DIC buttons, press the
set/reset button. The horn will sound twice to
indicate the TPMS receiver is ready, and
the TIRE LEARNING ACTIVE message will
display. If your vehicle does not have the DIC
buttons, press and hold the trip odometer
reset stem until the horn chirps twice and the
TIRE LEARNING ACTIVE message is
displayed.
