3. After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the "TPMS Telltale
Light" will flash on and off for 75 seconds and
then remain on solid.
4. For each subsequent ignition cycle, a chime
will sound and the "TPMS Telltale Light" will
flash on and off for 75 seconds and then
remain on solid.
5. Once you repair or replace the original road
tire and reinstall it on the vehicle in place of
the compact spare or non-matching full size
spare, the TPMS will update automatically
and the "TPMS Telltale Light" will turn off, as
long as no tire pressure is below the low-
pressure warning limit in any of the four
active road tires. 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.
Premium System — If Equipped
The Tire Pressure Monitor System (TPMS) uses
wireless technology with wheel rim mounted
electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of
the valve stem, transmit tire pressure readings
to the receiver module.
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle
monthly and to maintain the proper pressure.
The TPMS consists of the following compo-
nents:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System
messages, which will display in the instru-
ment cluster display.
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The "Tire Pressure Monitoring Telltale
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 instru-
ment cluster will display a "Tire Low" message,
an "Inflate to XX" message, and a graphic
showing the pressure values of each tire with
the low tire pressure values highlighted or 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 highlighted or in a different color in the
instrument cluster display graphic) to the vehi-
cle's recommended cold placard pressure
value, as shown in the "Inflate to XX" message.
Once the system receives the updated tire pres-
sures, the system will automatically update, the
pressure values in the graphic display in the
instrument cluster will stop being highlighted or
return to their original color, and the "Tire Pres-
sure Monitoring Telltale Light" will turn off.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(30 kPa) above the recommended cold placard
pressure in order to turn the Tire Pressure
Monitoring Telltale Light off.
