Caution
Tire sealant materials are not all the
same. A non-approved tire sealant could
damage the TPMS sensors. TPMS sensor
damage caused by using an incorrect tire
sealant is not covered by the vehicle
warranty. Always use only the GM
approved tire sealant available through
your dealer or included in the vehicle.
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 tire pressure warning
light flashes for about one minute and then
stays on for the remainder of the time the
vehicle is on. A DIC warning message also
displays. The malfunction light and DIC
warning message will come on each time
the vehicle is turned on until the problem is
corrected. Some of the conditions that can
cause these to come on are:
.One of the road tires has been replaced
with the spare tire. The spare tire does
not have a TPMS sensor. The malfunction
light and the DIC message should go off
after the road tire is replaced and thesensor matching process is performed
successfully. See "TPMS Sensor Matching
Process" later in this section.
.The TPMS sensor matching process was
not done or not completed successfully
after rotating the tires. The malfunction
light and the DIC message should go off
after successfully completing the sensor
matching process. See "TPMS Sensor
Matching Process" later in this section.
.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 tires or wheels do not match
the original equipment tires or wheels.
Tires and wheels other than those
recommended could prevent the TPMS
from functioning properly. See
Buying
New Tires 0298.
.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 tire pressure
condition. See your dealer for service if the
TPMS malfunction light and DIC message
come on and stay on.
Tire Fill Alert (If Equipped)
This feature provides visual and audible
alerts outside the vehicle to help when
inflating an underinflated tire to the
recommended cold tire pressure.
When the low tire pressure warning light
comes on:
1. Park the vehicle in a safe, level place.
2. Set the parking brake firmly.
3. Place the vehicle in P (Park).
4. Add air to the tire that is underinflated. The turn signal lamp will flash.
When the recommended pressure is
reached, the horn sounds once and the
turn signal lamp will stop flashing and
briefly turn solid.
Repeat these steps for all underinflated tires
that have illuminated the low tire pressure
warning light.

294 Vehicle Care
{Warning
Overinflating a tire could cause the tire
to rupture and you or others could be
injured. Do not exceed the maximum
pressure listed on the tire sidewall. See
Tire Sidewall Labeling0285 and
Vehicle Load Limits 0162.
If the tire is overinflated by more than
35 kPa (5 psi), the horn will sound multiple
times and the turn signal lamp will continue
to flash for several seconds after filling
stops. To release and correct the pressure,
while the turn signal lamp is still flashing,
briefly press the center of the valve stem.
When the recommended pressure is reached,
the horn sounds once.
If the turn signal lamp does not flash within
15 seconds after starting to inflate the tire,
the tire fill alert has not been activated or is
not working.
If the hazard warning flashers are on, the
tire fill alert visual feedback will not work
properly. The TPMS will not activate the tire fill alert
properly under the following conditions:.There is interference from an external
device or transmitter.
.The air pressure from the inflation device
is not sufficient to inflate the tire.
.There is a malfunction in the TPMS.
.There is a malfunction in the horn or turn
signal lamps.
.The TPMS sensor identification code is not
registered to the system.
.The TPMS sensor battery is low.
If the tire fill alert does not operate due to
TPMS interference, move the vehicle about
1 m (3 ft) back or forward and try again.
If the tire fill alert feature is not working,
use a tire pressure gauge.
Air Down Mode (If Equipped)
Air Down Mode allows the driver to set a
custom tire pressure for better traction
during off-road driving. Visual and audible
alerts outside of the vehicle will alert the
driver when the desired tire pressure has
been reached. To enable Air Down Mode:
1. Park the vehicle in a safe, level place.
2. Place the vehicle in P (Park).
3. Place the vehicle in ON/RUN or press and hold the ENGINE START/STOP button for
more than five seconds. See Ignition
Positions 0167.
4. Touch the Off-Road app icon on the infotainment home screen.
5. Touch the Air Down Mode icon.
6. Select the target pressure, then press START.
7. Choose which tire to deflate. Remove the valve cap, then press and hold the tire
valve stem.
During tire deflation, the turn signal
lamp closest to the tire being deflated
will start flashing.
When the target pressure you selected
in Step 6 is reached, the horn sounds
once and the turn signal lamp will stop
flashing and turn solid for several
seconds before turning off. Replace the
valve cap. Wait for the turn signal lamp
to turn off before deflating the next tire.
If you deflate the next tire while the
turn signal lamp is still on, the Air Down
Mode will not work properly.

GMC Canyon/Canyon Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-16510661) - 2023 - CRC - 11/29/22
Vehicle Care 295
Repeat Step 7 until all tires have been
deflated. Same steps can be followed for
inflating all tires to target pressure.
While in Air Down Mode, after all tires have
been deflated lower than the vehicle’s
recommended tire pressure, the low tire
pressure warning light and the DIC warning
message may come on for all tires.
Due to late air adjustment in a tire, the tire
pressure may change by 4 to 8 kpa (0.6 to
1.2 psi) after a few minutes, once you have
stopped deflation.
Ensure that the target pressure you select is
above or below your vehicle’s current tire
pressures by a least 20 kpa (3 psi).
If the tire is underinflated or overinflated by
more than 35 kPa (5 psi) from the target
pressure you selected in Step 6, the horn
will sound multiple times and the turn
signal lamp will continue to flash for several
seconds after tire pressure adjustment stops.
To correct the pressure, while the turn
signal lamp is still flashing, add air to inflate
the tire or briefly press the center of the
valve stem to deflate the tire. When the
target pressure you selected in Step 6 is
reached, the horn sounds once and the turn
signal lamp will stop flashing and turn solid
for several seconds before turning off. If the turn signal lamp does not flash within
15 seconds after starting to inflate the tire,
the Air Down Mode has not been activated
or is not working.
If the hazard warning flashers are on, the
Air Down Mode visual feedback will not
work properly.
The Air Down Mode will not work properly
under the following conditions:
.There is interference from an external
device or transmitter.
.The air pressure from the inflation device
is not sufficient to inflate the tire.
.There is a malfunction in the TPMS.
.There is a malfunction in the horn or turn
signal lamps.
.The TPMS sensor identification code is not
registered to the system.
.The TPMS sensor battery is low.
.The vehicle is not in P (Park).
.The vehicle is off.
.START was not pressed after selecting the
target tire pressure in the Air Down
Mode app.
If the Air Down Mode does not operate due
to TPMS interference, move the vehicle
about 1 m (3 ft) back or forward and try again. If the Air Down Mode is not working,
use a tire pressure gauge to confirm tire
pressure.
{Warning
Neither tire underinflation nor
overinflation is good. Underinflated
tires, or tires that do not have
enough air, can result in:
.Tire overloading and overheating,
which could lead to a blowout
.Premature or irregular wear
.Poor handling
.Reduced fuel economy for
internal combustion engine
vehicles
.Reduced range for electric vehicles
Overinflated tires, or tires that have
too much air, can result in:
.Unusual wear
.Poor handling
.Rough ride
.Needless damage from road
hazards
