Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE
PRESSURE” message will display in the instrument
cluster, an Inflate to XX message will be displayed and
a chime will sound when tire pressure is low in one or
more of the four active road tires. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
to the vehicle’s recommended cold placard pressure
value as shown in the Inflate to XXmessage. Once the
system receives the updated tire pressures, the system
will automatically update and the “Tire Pressure Moni-
toring 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.
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.
Service TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. The system fault will
also sound a chime. If the ignition is cycled, this sequence
will repeat, providing the system fault still exists. The

4. For each subsequent ignition cycle, a chime will soundand 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 levels. 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 components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System messages,
which display in the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID).
• 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 Driver Information
520 STARTING AND OPERATING
Page 523 of 702

Display (DID) will display anInflate to XXmessage and
a graphic showing the pressure values of each tire with
the low tire pressure values in a different color.
Should this occur, you should stop as soon as possible
and inflate the tires with low pressure (those in a
different color in the DID 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
DID will return to their original color, and the “Tire
Pressure Monitoring Telltale 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.
SERVICE TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for 75
seconds and then remain on solid. The system fault will
also sound a chime. In addition, the DID will display a
SERVICE SYSTEM message for a minimum of five
seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being
received.

If the ignition is cycled, this sequence will repeat, pro-
viding the system fault still exists. If the system fault no
longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, and the “SERVICE SYSTEMmessage will no longer display, and a pressure value will
display in place of the dashes. A system fault can occur
due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.

Vehicles With Compact Spare
1. The compact spare tire does not have a tire pressuremonitoring sensor. Therefore, the TPMS will not moni-
tor the pressure in the compact spare tire.
2. 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 cycle, the “TPMS
Telltale Light” will remain on and a chime will sound.
In addition, the graphic in the DID will still display a
different color pressure value and an Inflate to XX
message.
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. In addition, the DID will display a “SERVICE
SYSTEM” message for five seconds and then display
dashes (- -) in place of the pressure value. 4. For each subsequent ignition cycle, a chime will
sound, the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid, and the DID
will display a “SERVICE SYSTEM” message for five
seconds and then display dashes (- -) in place of the
pressure value.
5. 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
“TPMS Telltale Light” will turn off and the graphic in
the DID will display a new pressure value instead of
dashes (- -), 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.

5. After you have stopped pumping fuel, remove the fuelfiller nozzle and replace the fuel filler cap.
6. Tighten the fuel filler cap about one quarter turn until you hear one click. This is an indication that the fuel
filler cap is properly tightened.
7. To close the fuel filler door, push the center-rear edge (9 o’clock position) of the fuel filler door and then
release. The fuel filler door will latch closed.
NOTE:
• In certain cold conditions, ice may prevent the fuel
filler door from opening. If this occurs, lightly push on
the fuel filler door around the perimeter to break the
ice build up.
• If the fuel filler cap is not tightened properly, the MIL
will come on. Be sure the fuel filler cap is tightened
every time the vehicle is refueled.Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“CHECK GASCAP” message will be displayed in the
Electronic Vehicle Information Center (EVIC) or Driver
Information Display (DID). Refer to “Electronic Vehicle
Information (EVIC) or Driver Information Display
(DID)” in “Understanding Your Instrument Panel” for
further information. Tighten the fuel filler cap until a
“clicking” sound is heard. This is an indication that the
fuel filler cap is properly tightened. Refer to “Onboard
Diagnostic System” in “Maintaining Your Vehicle” for
further information.

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
“CHECK GASCAP” message will be displayed in the
Electronic Vehicle Information Center (EVIC) or Driver
Information Display (DID). Refer to “Electronic Vehicle
Information (EVIC) or Driver Information Display
(DID)” in “Understanding Your Instrument Panel” for

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 will influence when the “Oil
Change Required” message is displayed. Severe Operat-
ing 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 “Oil Change Reset”
in “Electronic Vehicle Information Center (EVIC)” or
Driver Information Display (DID)” in “Understanding
Your Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km), twelve months or
350 hours of engine run time, whichever comes first. The
350 hours of engine run or idle time is generally only a
concern for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment or is
operated predominately at idle or only very low engine
RPM’s. This type of vehicle use is considered Severe
Duty.
