Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Warning
Light will illuminate in the instrument
cluster and a chime will sound when
tire pressure is low in one or more of
the four active road tires. In addition, the
instrument cluster will display a "Tire Low"
message for a minimum of five seconds, an
"Inflate to XX" message and a graphic showing
the pressure values of each tire with the low tire
pressure values in a different color.
Tire Pressure Monitoring Low Pressure Warning
Should this occur, you should stop as soon as
possible and inflate the tires with low pressure
(those in a different color in the instrument
cluster graphic) to the vehicle’s recommended
cold placard pressure value as shown in the
"Inflate to XX" message. Once the system
receives the updated tire pressures, the system
will automatically update, the pressure values
in the graphic display in the instrument cluster
will return to their original color, and the Tire
Pressure Monitoring Warning Light will turn off.
The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order
for the TPMS to receive this information.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the Tire Pressure Moni-
toring Warning Light off.
Tire Fill Alert
Tire Fill Alert notifies the user when the placard
tire pressure is attained while inflating or
deflating the tire.
The customer may choose to disable or enable
the Tire Fill Alert feature through use of the
customer settings in the radio.
NOTE:
Only one tire can be filled at a time when
using the Tire Fill Alert system.
The Tire Fill Alert feature cannot be entered if
an existing TPM system fault is set to “active”
or if the system is in deactivation mode
(if equipped).
The system will be activated when the system
detects an increase of tire pressure while
inflating the tire. The ignition must be in the
RUN mode, with the transmission in PARK (P).
NOTE:
It is not required to have the engine running to
enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode.
When Tire Fill Alert Mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster.
