pressure value as shown in theInflate to XXmessage.
Once the system receives the updated tire pressures, the
system will automatically update and the TPM Telltale
Light and LOW TIRE message 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
If a system fault is detected, the TPM 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
switch is cycled, this sequence will repeat, providing the
system fault still exists. The TPM Telltale Light will turn
off when the fault condition no longer exists. A system
fault can occur due to any of the following:
1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as
the TPM sensors. 2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of 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.
Vehicles With Full Size Spare
1. The matching full size spare wheel and tire assembly has a TPM sensor that can be monitored by the TPMS.
2. If you install the full size spare in place of a road tire that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a chime will
sound and the TPM Telltale Light and LOW TIRE
message will turn ON. The Inflate to XXmessage
will also be displayed.
444 STARTING AND OPERATING
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 TPM sensors
• Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC)
• TPM Telltale Light The matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor. The full size spare can be
used in place of any of the four road tires. The TPMS will
only monitor the pressure in the full size spare tire when
it is used in place of a road tire. Otherwise, a spare with
a pressure below the low-pressure limit will not cause the
TPM Telltale Light to illuminate or the chime to sound.
Tire Pressure Monitoring Low Pressure Warnings
The TPM 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 EVIC will display a LOW TIRE
message and a graphic showing the pressure values of
each tire with the low tire pressure values flashing or
changing color. An Inflate to XXmessage will also be
displayed.
446 STARTING AND OPERATING
Service TPMS Warning
If a system fault is detected, the TPM 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
EVIC will display aSERVICE TPM 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 switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the TPM Telltale Light will no longer
flash, and the SERVICE TPM SYSTEM message 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. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as
the TPM sensors. 2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of 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.
The EVIC will also display a SERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault related to an incorrect sensor location fault is
detected. In this case, the SERVICE TPM SYSTEM
message is then followed with 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 located in the correct vehicle
position. The system still needs to be serviced as long as
the SERVICE TPM SYSTEM message is displayed.
448 STARTING AND OPERATING
Vehicles With Full Size Spare
1. The matching full size spare wheel and tire assemblyhas a TPM sensor that can be monitored by the TPMS.
2. If you install the full size spare in place of a road tire that has a pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a chime will
sound and the TPM Telltale Light will turn ON. In
addition, the EVIC will display a low pressure mes-
sage and a graphic showing the low tire pressure
value flashing or in a different color. An Inflate to XX
message will also be displayed.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h) the TPM Telltale Light will turn
OFF, and the pressure value displayed will be updated
and stop flashing or return to its original color as long
as no tire pressure is below the low-pressure warning
limit in any of the four active road tires. Vehicles With Compact Spare
1. The compact spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor 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 switch cycle, the TPM
Telltale Light will remain ON and a chime will sound.
In addition, the graphic in the EVIC will still display a
flashing pressure value or a pressure value in a
different color. An Inflate to XXmessage will also be
displayed.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPM 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.

WARNING!
Because the front wheels steer the vehicle, it is
important that you do not exceed the maximum front
or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and the
front and rear GAWR.
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.Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle-by-axle and side-by-side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.

Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer weight ratings towable for your given drivetrain.
Engine/TransmissionFrontal AreaMax. GTW (Gross
Trailer Weight) Max. Tongue Weight (See
Note)
3.6L Automatic 22 sq ft (2.04 sq m) 1,000 lbs (454 kg) 100 lbs (45 kg)
5.7L Automatic 32 sq ft (2.97 sq m) 1,000 lbs (454 kg) 100 lbs (45 kg)
Refer to local laws for maximum trailer towing speeds.
NOTE: The trailer tongue weight must be considered as
part of the combined weight of occupants and cargo, and
it should never exceed the weight referenced on the “Tire
and Loading Information” placard. Refer to “Tire Safety
Information” in “Starting and Operating” for further
information.
Trailer And Tongue Weight
Always load a trailer with 60% to 65% of the weight in
the front of the trailer. This places 10% to 15% of the
Gross Trailer Weight (GTW) on the tow hitch of your
vehicle. Loads balanced over the wheels or heavier in the
rear can cause the trailer to sway severelyside to side
which will cause loss of control of the vehicle and trailer.
Failure to load trailers heavier in front is the cause of
many trailer collisions.

Towing Requirements
To promote proper break-in of your new vehicle drive-
train components the following guidelines are recom-
mended:
WARNING!
Improper towing can lead to an injury collision.
Follow these guidelines to make your trailer towing
as safe as possible:
•Make certain that the load is secured in the trailer
and it will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
(Continued)
WARNING! (Continued)
•When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance, or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure, or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the frame or hook retainers of the vehicle hitch.
Cross the chains under the trailer tongue and allow
enough slack for turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle automatic
transmission in PARK. Always, block or chock
the trailer wheels.
• GCWR must not be exceeded.
(Continued)

STARTING AND OPERATING 471
avoids frequent downshifts. For example, choose “4” if
the desired speed can be maintained. Choose “3” or
“2” if needed to maintain the desired speed.
• To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as neces-
sary to avoid extended driving at high RPM. Return to
a higher gear or vehicle speed when grade and road
conditions allow.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed. Air Conditioning
Turn off temporarily.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Two-Wheel Drive And All-Wheel Drive
Recreational towing (with all four wheels on the ground,
or using a tow dolly) is
NOT ALLOWED. The only
acceptable method for towing this vehicle (behind an-
other vehicle) is on a vehicle trailer with all four wheels
OFF the ground.
CAUTION!
Towing this vehicle in violation of the above require-
ments can cause severe transmission and/or transfer
case damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.
