GMC Acadia 15919282 Owner's Manual page 333

When a low tire pressure condition is
detected, the TPMS illuminates the
low tire pressure warning light
located on the instrument panel
cluster.
At the same time a message to
check the pressure in a specific tire
appears on the Driver Information
Center (DIC) display. The low tire
pressure warning light and the DIC
warning message come on at each
ignition cycle until the tires are
inflated to the correct inflation
pressure. Using the DIC, tire
pressure levels can be viewed by the
driver. For additional information and
details about the DIC operation and
displays see DIC Operation and
Displays (With DIC Buttons) on
page 3-47 or DIC Operation and
Displays (Without DIC Buttons) on
page 3-53 and DIC Warnings and
Messages on page 3-58.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as you start to drive. This
could be an early indicator that the
air pressure in the tire(s) are getting
low and need to be inflated to the
proper pressure.
A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle's
original equipment tires and the
correct inflation pressure for your
vehicle's tires when they are cold.
See Loading the Vehicle on
page 4-16, for an example of the
Tire and Loading Information label
and its location on your vehicle.
Also see Inflation - Tire Pressure
on page 5-43.
Service and Appearance Care
Your vehicle's TPMS can warn you
about a low tire pressure condition
but it does not replace normal
tire maintenance. See Tire
Inspection and Rotation on
page 5-50 and Tires on page 5-37.
Notice: Using non-approved tire
sealants could damage the Tire
Pressure Monitor System (TPMS)
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use the
GM approved tire sealant available
through your dealer/retailer.
Factory-installed Tire Inflator Kits use
a GM approved liquid tire sealant.
Using non-approved tire sealants
could damage the TPMS sensors.
See Tire Sealant and Compressor
Kit on page 5-58 for information
regarding the inflator kit materials
and instructions.
