CAUTION!(Continued)
moisture and dirt from entering the valve stem,
which could damage the TPMS sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
This is the TPMS warning indicator located in the
instrument cluster.
The 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.
498 STARTING AND OPERATING
NOTE:It is particularly important for you to check the
tire pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, a LOW TIRE PRESSURE
message and “Inflate Tire to XX” message will be dis-
played for a minimum of five seconds, and an audible
chime will be activated when one or more of the four
active road tire pressures are low. 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. The recommended cold placard pressure value is
the pressure value in the
Inflate Tire to XXmessage
displayed in the EVIC/DID. The system will automati-
cally update and the Tire Pressure Monitoring Light will
extinguish and the LOW TIRE PRESSURE and “Inflate
Tire to XX” messages will turn off once the updated tire
pressures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) to
receive this information.
Service TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and then remain on solid when a
system fault is detected. The system fault will also sound
a chime and display a “SERVICE TPM SYSTEM” mes-
sage for a minimum of five seconds. If the ignition key is
cycled, this sequence will repeat providing the system
fault still exists. The Tire Pressure Monitoring Telltale
5
STARTING AND OPERATING 499
Light will turn off when the fault condition no longer
exists. A system fault can occur with any of the following
scenarios:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE: Your vehicle is equipped with a compact spare
wheel and tire assembly.
1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not moni-
tor the tire 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 key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
and LOW TIRE PRESSURE and “Inflate Tire to XX”
messages will still turn ON due to the low tire.
3. However, after driving the vehicle for up to 20 min- utes 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 and a “SERVICE
TPM SYSTEM” message will be displayed for a mini-
mum of five seconds.
4. For each subsequent ignition key cycle, a chime will sound and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on
solid and a “SERVICE TPM SYSTEM” message will be
displayed for a minimum of five seconds.
500 STARTING AND OPERATING
5. Once you repair or replace the original road tire andreinstall it on the vehicle in place of the compact spare
tire, the TPMS will update automatically and the Tire
Pressure Monitoring 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 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 your tires regularly 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 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. The audible chime will sound once
every ignition cycle for the first condition that it detects.
In addition, the EVIC/DID will display a “Inflate Tire to
XX” message for a minimum of five seconds and a
graphic of the pressure value(s) with the low tire(s)
5
STARTING AND OPERATING 501
displayed in a different color. The recommended cold
placard pressure inflation value is the pressure value
displayed in theInflate Tire to XX message displayed in
the EVIC/DID.
Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible
and inflate all tires that are in a different color on the
graphic display to the vehicle’s recommended cold plac-
ard pressure value. The system will automatically up-
date, the “Inflate Tire to XX” message will no longer be
displayed, the graphic display of the pressure value(s)
will return to their normal color, and the Tire Pressure
Monitoring Light will extinguish once the updated tire
pressure(s) have been received. The vehicle may need to
be driven for up to 20 minutes above 15 mph (24 km/h)
to receive this information.Service TPMS Message
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and then remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC/DID will display a “SERVICE TPM
SYSTEM” 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
Tire Pressure Monitoring Sensor(s) is not being received.
If the ignition key 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
with any of the following scenarios:

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight values are
determined by weighing your vehicle on a commercial
scale before any occupants or cargo are added.
Overloading
The load carrying components (springs, tires, wheels,
etc.) of your vehicle will provide satisfactory service as
long as you do not exceed the GVWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.

Towing Requirements — Tires
•Do not attempt to tow a trailer while using a compact
spare tire.
• Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting And Oper-
ating” for proper tire inflation procedures.
• Check the trailer tires for proper tire inflation pres-
sures before trailer usage.
• Check for signs of tire wear or visible tire damage
before towing a trailer. Refer to “Tires – General
Information” in “Starting And Operating” for the
proper inspection procedure.
• When replacing tires, refer to “Tires – General Infor-
mation” in “Starting And Operating” for proper tire replacement procedures. Replacing tires with a higher
load carrying capacity will not increase the vehicle’s
GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
•
Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically
actuated brakes. When towing a trailer equipped with
a hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (450 kg) and required for trailers in excess of
2,000 lbs (907 kg).
