CAUTION!(Continued)
•Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
•
Do not drive for a prolonged period on dry pavement.
• Observe the traction device manufacturer ’s instruc-
tions on the method of installation, operating speed,
and conditions for use. Always use the suggested
operating speed of the device manufacturer ’s if it is
less than 30 mph (48 km/h).
• Do not use traction devices on a compact spare tire.
TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates.
These effects can be reduced by timely rotation of tires. The
benefits of rotation are especially worthwhile with aggres-
sive tread designs such as those on On/Off-Road type tires.
Rotation will increase tread life, help to maintain mud,
snow, and wet traction levels, and contribute to a smooth,
quiet ride. Refer to the “Maintenance Schedule” for the proper main-
tenance intervals. More frequent rotation is permissible if
desired. The reasons for any rapid or unusual wear should
be corrected prior to rotation being performed.
NOTE:
The premium Tire Pressure Monitor System will
automatically locate the pressure values displayed in the
correct vehicle position following a tire rotation.
The suggested rotation method is the “rearward-cross”
shown in the following diagram.

438 STARTING AND OPERATING
TIRE PRESSURE MONITOR SYSTEM (TPMS)
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 regularly
check the tire pressure in all of your tires and to maintain
the proper pressure. The Tire Pressure Monitor System (TPMS) consists of the
following components:
•
Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Various Tire Pressure Monitoring System Messages,
which display in the instrument cluster, and a graphic
displaying tire pressures.
• Tire Pressure Monitoring Telltale Light.
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold tire placard pressure.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will de-
crease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after the vehicle has not been driven for at least three
hours, or driven less than 1 mile (1.6 km) after a three-hour
period. Refer to “Tires – General Information” in “Start-
ing And Operating” for information on how to properly
inflate the vehicle’s tires. The tire pressure will also
increase as the vehicle is driven - this is normal and there
should be no adjustment for this increased pressure.
Tire Pressure Monitor Display

STARTING AND OPERATING 439
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning thresh-
old for any reason, including low temperature effects, or
natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above recommended cold
tire placard pressure. Once the low tire pressure warning
has been illuminated, the tire pressure must be increased to
the recommended cold tire pressure in order for the Tire
Pressure Monitoring Telltale Light to be turned 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 system will automatically update and the Tire Pressure
Monitoring Telltale Light will extinguish 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.
For example, your vehicle has a recommended cold
(parked for more than three hours) tire placard pressure of
33 psi (227 kPa). If the ambient temperature is 68°F (20°C) and the measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is sufficiently low enough to turn ON the Tire
Pressure Monitoring Telltale Light. Driving the vehicle
may cause the tire pressure to rise to approximately 28 psi
(193 kPa), but the Tire Pressure Monitoring Telltale Light
will still be ON. In this situation, the Tire Pressure Moni-
toring Telltale Light will turn OFF only after the tires have
been inflated to the vehicle’s recommended cold tire pres-
sure value.
CAUTION!
•
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
(Continued)
440 STARTING AND OPERATING
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 in a different color on the graphic
display to the vehicle’s recommended cold tire pressure
displayed in theInflate to XXXmessage.
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 system will automatically update, the graphic display of
the pressure value(s) will return to its original color and the
Tire Pressure Monitoring Telltale 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 TPM System Warning
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 instrument cluster will display a “SERVICE TPM
SYSTEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with “- -“ in
place of the pressure value(s), indicating which Tire Pres-
sure Monitoring 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:
1. Jamming due to electronic devices or driving next to facilities emitting the same Radio Frequencies as the
TPM sensors.
Low Tire Pressure Monitor Display
442 STARTING AND OPERATING
2. Installing some form of aftermarket window tinting thataffects 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 TPM sensors.
NOTE: There is no tire pressure monitoring sensor in the
spare tire. The TPMS will not be able to monitor the tire
pressure. If you install the spare tire in place of a road tire
that has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, the Tire Pressure
Monitoring Telltale Light will remain ON, a chime will
sound, and the instrument cluster will still display a
pressure value in the different color graphic display and an
Inflate to XXX kPa message will be displayed. 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 instrument cluster will display a “SERVICE
TPM SYSTEM message for 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 instru-
ment cluster will display a
SERVICE TPM SYSTEM
message for 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 spare tire, the TPMS will update automatically.
In addition, the Tire Pressure Monitoring Telltale Light will
turn OFF and the graphic in the instrument cluster 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.
TPMS Deactivation — If Equipped
The TPMS can be deactivated if replacing all four wheel
and tire assemblies (road tires) with wheel and tire assem-
blies that do not have TPMS Sensors, such as when
installing Winter wheel and tire assemblies on your ve-
hicle. To deactivate the TPMS, first, replace all four wheel
and tire assemblies (road tires) with tires not equipped
with Tire Pressure Monitoring (TPM) Sensors. Then, drive
the vehicle for 10 minutes above 15 mph (24 km/h). The
TPMS will chime, the “TPM Telltale Light” will flash on
and off for 75 seconds and then remain on and the
5
STARTING AND OPERATING 443
instrument cluster will display the “SERVICE TPM SYS-
TEM” message and then display dashes (--) in place of the
pressure values. Beginning with the next ignition switch
cycle, the TPMS will no longer chime or flash the TPM
telltale and display the “SERVICE TPM SYSTEM” message
in the instrument cluster display but dashes (--) will remain
in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPM sen-
sors. Then, drive the vehicle for up to 10 minutes above
15 mph (24 km/h). The TPMS will chime, the “TPM Telltale
Light” will flash on and off for 75 seconds and then turn off,
and the instrument cluster will display the “SERVICE TPM
SYSTEM” message. The instrument cluster will also display
pressure values in place of the dashes. On the next ignition
switch cycle the “SERVICE TPM SYSTEM” message will no
longer be displayed as long as no system fault exists.

FUEL REQUIREMENTS
3.6L Engine
This engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when
using high-quality unleaded “Regular”
gasoline having an octane rating of 87 as
specified by the (R+M)/2 method. The
use of higher octane “Premium” gaso-
line will not provide any benefit over “Regular” gasoline in
these engines.
444 STARTING AND OPERATING
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s 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.
Loading
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to insure that the GVWR has not been exceeded. The
weight on the front and rear of the vehicle should then be
determined separately to be sure that the load is properly
distributed over the front and rear axle. Weighing the
vehicle may show that the GAWR of either the front or rear
axles has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from front to
rear or rear to front as appropriate until the specified
452 STARTING AND OPERATING
Towing Requirements
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended.
CAUTION!
•Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
• Then, during the first 500 miles (805 km) that a trailer
is towed, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps the engine
and other parts of the vehicle wear in at the heavier
loads.
Perform the maintenance listed in the “Maintenance
Schedule”. Refer to “Maintenance Schedule” for the proper
maintenance intervals. When towing a trailer, never exceed
the GAWR or GCWR ratings.
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
• Make certain that the load is secured in the trailer
and 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.
• When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or damage
to brakes, axle, engine, transmission, steering, sus-
pension, chassis structure or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
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 transmission in
