the tyres and transmit the tyre
pressure readings to a receiver
located in the vehicle.
When a low tyre pressure condition
is detected, the TPMS illuminates
the low tyre pressure warning light
located on the instrument cluster.
If the warning light comes on, stop
as soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. See Vehicle Load
Limits on page 9-14.
A message to check the pressure in
a specific tyre displays in the Driver
Information Centre (DIC). The low
tyre pressure warning light and the
DIC warning message come on at
each ignition cycle until the tyres
are inflated to the correct inflation
pressure. Using the DIC, tyre
pressure levels can be viewed. For
additional information and details
about the DIC operation and
displays, see Driver Information
Centre (DIC) on page 5-22 and Tyre
Messages on page 5-34.
The low tyre pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the
air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tyre and Loading Information
label shows the size of the original
equipment tyres and the correct
inflation pressure for the tyres when
they are cold. See Vehicle Load
Limits on page 9-14, for an example
of the Tyre and Loading Information
label and its location. Also see Tyre
Pressure on page 10-43.
The TPMS can warn about a low
tyre pressure condition but it does
not replace normal tyre
maintenance. See Tyre Inspection
on page 10-48, Tyre Rotation on
page 10-49, and Tyres on
page 10-40.
Notice: Tyre sealant materials are
not all the same. A non-approved
tyre sealant could damage the
TPMS sensors. TPMS sensor
damage caused by using an
incorrect tyre sealant is not
covered by the vehicle warranty.
Always use only the
GM-approved tyre sealant
available through your dealer or
included in the vehicle.
