TPMS Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more of the four active road tire
pressures are low. In addition, the EVIC will display a
“LOW TIRE” message and a graphic display of the
pressure value(s) with the low tire(s) flashing. AnInflate
Tire to XX message will also be displayed.
Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is flashing on the graphic
display to the vehicle’s recommended cold tire pressure
value as shown in the Inflate Tire to XXmessage. The
system will automatically update, the graphic display of
the pressure value(s) will stop flashing, and the “Tire
Pressure Monitoring Telltale Light” will extinguish once
the updated tire pressure(s) have been received. NOTE:
The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this infor-
mation.
SERVICE TPM SYSTEM Message
The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This text
message is then followed by a graphic display, with --in
place of the pressure value(s) indicating which TPMS
Sensor(s) is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, the “SERVICE TPM SYSTEM”

message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following scenarios:
•Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
• Installing some form of aftermarket window tinting
that affects radio wave signals.
• Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
The EVIC will also display a “SERVICE TPM SYSTEM”
message for a minimum of five seconds when a system
fault possibly related to an incorrect sensor location fault
is present. In this case, the “SERVICE TPM SYSTEM” message is then followed by a graphic display with
pressure values still shown. This indicates that the pres-
sure values are still being received from the TPM sensors
but they may not be in the correct vehicle position. The
system still needs to be serviced as long as the “SERVICE
TPM SYSTEM” message exists.
Vehicles With Compact Spare
•
The compact spare tire (if equipped) does not have a
TPMS. Therefore, the TPMS will not monitor the
pressure in the compact spare tire.
• If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition switch cycle, the “Tire
Pressure Monitoring Telltale Light” will remain on, the
“LOW TIRE” message will be displayed, a chime will
sound, and the EVIC will still display a flashing
pressure value and the Inflate Tire to XXmessage in
the graphic display.
508 STARTING AND OPERATING
•After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “Tire Pressure Monitoring
Telltale Light” will flash on and off for 75 seconds and
then remain on solid. In addition, the EVIC will
display a “SERVICE TPM SYSTEM” message for a
minimum of five seconds and then display dashes (- -)
in place of the pressure value.
• For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid, and the EVIC will display a “SERVICE TPM
SYSTEM” message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value.
• Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“Tire Pressure Monitoring Telltale Light” will turn off and the graphic in the EVIC will display a new
pressure value instead of dashes (- -), as long no tire
pressure is below the low pressure warning limit in
any of the four active road tires.
NOTE: 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.

520 STARTING AND OPERATING
ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability.
The vehicle must be serviced before any emissions
tests can be performed.
• If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“gASCAP” message will display in the odometer or a
“CHECK GASCAP” message will be displayed in the
Electronic Vehicle Information Center (EVIC). Refer to
576 MAINTAINING YOUR VEHICLE
MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Oil Change Required” message is
displayed. Severe Operating Conditions can cause the
change oil message to illuminate as early as 3,500 miles
(5,600 km) since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone otherthan your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)/Oil Change Required” in
“Understanding Your Instrument Panel” for further in-
formation.
NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
