Vehicle Care
Factory-installed Tyre Inflater Kits use a
GM-approved liquid tyre sealant. Using
non-approved tyre sealants could damage
the TPMS sensors. See
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 pressure 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. The spare tyre does
not have a TPMS sensor. The malfunction
light and DIC message should go off after
the road tyre is replaced and the sensor
matching process is performed
successfully. See
“
TPMS Sensor Matching
Process
”
following.
.
The TPMS sensor matching process was
not done or not completed successfully
after rotating the tyres. The malfunction
light and the DIC message should go off
after successfully completing the sensor
matching process. See "TPMS Sensor
Matching Process" following.
.
One or more TPMS sensors are missing or
damaged. The malfunction light and the
DIC message should go off when the
TPMS sensors are installed and the sensor
matching process is performed
successfully. See your dealer for service.
.
Replacement tyres or wheels do not
match the original equipment tyres or
wheels. Tyres and wheels other than
those recommended could prevent the
TPMS from functioning properly. See
.
.
Operating electronic devices or being near
facilities using radio wave frequencies
similar to the TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning properly, it
cannot detect or signal a low tyre pressure
condition. See your dealer for service if the
TPMS malfunction light and DIC message
come on and stay on.
Tyre Fill Alert (If Equipped)
This feature provides visual and audible
alerts outside the vehicle to help when
inflating an underinflated tyre to the
recommended cold tyre pressure.
When the low tyre pressure warning light
comes on:
1. Park the vehicle in a safe, level place.
2. Apply the parking brake firmly.
3. Place the vehicle in P (Park).
4. Add air to the tyre that is underinflated.
The indicator lamp will flash.
When the recommended pressure is
reached, the horn sounds once and the
indicator lamp will stop flashing and
briefly turn solid.
Repeat these steps for all underinflated
tyres that have illuminated the low tyre
pressure warning light.

Warning
Overinflating a tyre could cause the tyre
to rupture and you or others could be
injured. Do not exceed the maximum
pressure listed on the tyre sidewall.
