WARNING! (Continued)
•Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This
may cause the seat heater to overheat. To avoid
heated seat surfaces coming in contact and poten-
tial seat overheating, ALWAYS ensure that the seat
heater is in the off position (amber lights indicate
High/Low/Off) before placing any of the seats into
a folded flat position (if equipped).
Rear Heated Seats — If Equipped
On vehicles equipped with rear heated seats, the seats
closest to the doors are heated. The controls for these
seats are located on the rear of the center console.Press the switch once to select the High setting.
Press the switch a second time, to select the
Low setting. Press the switch a third time to
turn the heating elements Off.Rear Heated Seat Switches

When the High setting is selected, the heater will provide
a boosted heat level during the first four minutes of
operation. Then, the heat output will drop to the normal
High-temperature level. If the High setting is selected,
the system will automatically switch to Low after 30 min-
utes of continuous operation. At that time, the number of
illuminated LEDs changes from two to one, indicating
the change. The Low setting will turn Off automatically
after 30 minutes.
NOTE:Once a heat setting is selected, heat will be felt
within two to five minutes.WARNING!
•Persons who are unable to feel pain to the skin
because of advanced age, chronic illness, diabetes,
spinal cord injury, medication, alcohol use, ex-
haustion or other physical condition must exercise
care when using the seat heater. It may cause burns
even at Low temperatures, especially if used for
long periods of time.
•Do not place anything on the seat that insulates
against heat, such as a blanket or cushion. This
may cause the seat heater to overheat. To avoid
heated seat surfaces coming in contact and poten-
tial seat overheating, always ensure that the seat
heater is in the Off position (amber lights indicate
High/Low/Off) before placing any of the seats into
a folded flat position (if equipped).

6. Firmly press and release the “learn” or “training”
button. The name and color of the button may vary by
manufacturer.
NOTE:There are 30 seconds in which to initiate the next
step after the “Learn” button has been pressed.
7. Return to the vehicle and press the programmed
HomeLinkbutton twice (holding the button for two
seconds each time). If the device is plugged in and
activates, programming is complete.
If the device does not activate, press the button a third
time (for two seconds) to complete the training.
If you have any problems, or require assistance, please
call toll-free 1–800–355–3515 or, on the Internet at
www.HomeLink.com for information or assistance.
To program the remaining two HomeLinkbuttons,
repeat each step for each remaining button. DO NOT
erase the channels.Gate Operator/Canadian Programming
Canadian radio-frequency laws require transmitter sig-
nals to “time-out” (or quit) after several seconds of
transmission – which may not be long enough for
HomeLinkto pick up the signal during programming.
Similar to this Canadian law, some U.S. gate operators are
designed to “time-out” in the same manner.
It may be helpful to unplug the device during the cycling
process to prevent possible overheating of the garage
door or gate motor.
If you are having difficulties programming a garage door
opener or a gate operator, replace “Programming
HomeLink” Step 3 with the following:
3. Continue to press and hold the HomeLinkbutton
while you press and release - every two seconds
(“cycle”) your hand-held transmitter until HomeLink
has successfully accepted the frequency signal. The
EVIC display will change from “CHANNEL # TRAIN-
ING” to “CHANNEL # TRAINED.”

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant, during summer, to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50%
concentration is recommended. Refer to Fluids, Lubri-
cants, and Genuine Parts in Section 7 for the proper
coolant type.
When using the air conditioner in extremely heavy traffic, in
hot weather, especially when towing a trailer, additional
engine cooling may be required. If this situation is encoun-
tered, operate the transmission in a lower gear to increase
engine RPM, coolant flow and fan speed. When stopped inheavy traffic, it may be necessary to shift into NEUTRAL
and depress the accelerator slightly for fast idle operation to
increase coolant flow and fan speed.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months, make
sure the air intake, located directly in front of the wind-
shield, is free of ice, slush, snow, or other obstructions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.

STARTING PROCEDURE
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
•Never leave children alone in a vehicle. Leaving
unattended children in a vehicle is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Do not leave the key in
the ignition. A child could operate power win-
dows, other controls, or move the vehicle.
•Do not leave animals or children inside parked
vehicles in hot weather; interior heat buildup may
cause serious injury or death.

WARNING! (Continued)
•Be sure to turn off the engine and remove the key
from the ignition switch if you want to rest or
sleep in your car. Accidents can be caused by
inadvertently moving the shift lever. Accidents
can also be caused by pressing the accelerator
pedal. This may cause excessive heat in the ex-
haust system, resulting in overheating and vehicle
fire, which may cause serious or fatal injuries.
Keyless Go (If Equipped)
This function allows the driver to op-
erate the ignition switch with the push
of a button, as long as the ENGINE
START/STOP button is installed and
the Keyless Go ignition key (FOBIK)
can be detected inside of the vehicle.

When To Use TOW/HAUL Mode — If Equipped
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, press the TOW/HAUL switch. This will improve
performance and reduce the potential for transmission
overheating or failure due to excessive shifting. When
operating in TOW/HAUL mode, the transmission will
shift into direct gear and Overdrive will be enabled
under steady cruise conditions.
The “TOW/HAUL” indicator light will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the TOW/HAUL mode is desired,
the switch must be pressed each time the engine is
started.

NOTE:
•The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm [usu-
ally after 1 to 3 miles (1.6 to 4.8 km) of driving].
Because the engine speed is higher when the torque
converter clutch is not engaged, it may seem as if the
transmission is not shifting into Overdrive when cold.
This is normal. Manually shifting (using the ERS shift
control) between 4 (direct gear) and 5/D (Overdrive
gear) positions will demonstrate that the transmission
is able to shift into and out of Overdrive. For vehicles
with 4.7L or 5.7L engines (which have two Overdrive
gears), the transmission may not shift into the top
Overdrive gear (normal 5th gear) until the transmis-
sion fluid and engine coolant are warm.
•If the vehicle has not been driven in several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter intothe transmission. This condition is normal and will not
cause damage to the transmission. The torque con-
verter will refill within five seconds of shifting from
PARK into any other gear position.
Rocking The Vehicle
If the vehicle becomes stuck in snow, sand, or mud, it can
often be moved by a rocking motion. Move the shift lever
between DRIVE and REVERSE, while applying slight
pressure to the accelerator.
NOTE:The Electronic Stability Program (ESP) and
Traction Control (if equipped) should be turned OFF
before attempting to rock the vehicle. Refer to “Electronic
Brake Control System” in Section 3 of this manual.
The least amount of accelerator pedal pressure to main-
tain the rocking motion, without spinning the wheels or
racing the engine, is most effective. Racing the engine or
spinning the wheels, due to the frustration of not freeing
the vehicle, may lead to transmission overheating and
306 STARTING AND OPERATING

failure. Allow the engine to idle with the shift lever in
NEUTRAL for at least one minute after every five
rocking-motion cycles. This will minimize overheating
and reduce the risk of transmission failure during pro-
longed efforts to free a stuck vehicle.
CAUTION!
When “rocking” a stuck vehicle by moving between
“First” and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
FOUR-WHEEL DRIVE OPERATION
Quadra-Trac IOperating
Instructions/Precautions — If Equipped
The Quadra-Trac Iis a single-speed (HI range only)
transfer case, which provides convenient full-time four–wheel drive. No driver interaction is required. The Brake
Traction Control System (BTC), which combines standard
ABS and Traction Control, provides resistance to any
wheel that is slipping to allow additional torque transfer
to wheels with traction.
NOTE:The Quadra-Trac Isystem is not appropriate
for conditions where 4WD LOW range is recommended.
Refer to “Off-Road Driving Tips” in this section.
Quadra-Trac IIOperating
Instructions/Precautions — If Equipped
The Quadra-Trac IItransfer case is fully automatic in the
normal driving 4WD HI mode. The Quadra-Trac II
transfer case provides three mode positions — 4WD HI,
NEUTRAL, and 4WD LOW.
This transfer case is fully automatic in the 4WD HI mode.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
switch bank just above the climate controls.
Press the switch to turn on the Hazard
Warning flashers. When the Hazard
Warning flasher switch is activated, all
directional turn signals will flash on
and off to warn oncoming traffic of an
emergency. Press the switch a second
time to turn off flashers.
This is an emergency warning system and should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and is creating a safety hazard for
other motorists.
If it is necessary to leave the vehicle to go for service, the
Hazard Warning flasher will continue to operate with the
ignition key removed and the vehicle locked.NOTE:With extended use, the Hazard Warning flasher
may run down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put transmission in
NEUTRAL, but do not increase engine idle speed.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the temperature
control to maximum heat, the mode control to floor, and

Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tuneup to manufacturer’s specifica-
tions, should be obtained immediately.
