as soon as possible and inflate the
tyres to the recommended pressure
shown on the tyre loading
information label. See Vehicle Load
Limits on page 9 9.
A message to check the pressure in
a specific tyre displays in the DIC
display screen. The low tyre
pressure warning light and the DIC
warning message come at each
ignition cycle until the tyres are
inflated to the correct inflation
pressure. Using the Driver
Information Centre (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 28 and Tyre
Messages on page 5 45.
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.
The 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 9, for an example
of the Tyre and Loading Information
label and its location. Also see Tyre
Pressure on page 10 61.
The TPMS can warn about a low
tyre pressure condition but it does
not replace normal tyre
maintenance. See Tyre Inspection
on page 10 67, Tyre Rotation on
page 10 67 and Tyres on
page 10 59.
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.
Vehicle Care
Factory-installed Tyre Inflator Kits
use a GM approved liquid tyre
sealant. Using non-approved tyre
sealants could damage the TPMS
sensors. See Tyre Sealant and
Compressor Kit on page 10 76 for
information regarding the inflator kit
materials and instructions.
TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
system detects a malfunction, the
low tyre warning light flashes for
about one minute and then stays on
for the remainder of the ignition
cycle. A DIC warning message also
displays. The malfunction light and
DIC warning message come on at
each ignition cycle until the problem
is corrected. Some of the conditions
that can cause these to come
on are:
One of the road tyres has been
replaced with the spare tyre,
if the vehicle has one. The spare
