Recirculation
When outside air contains smoke, odors, or high humidity,
or if rapid cooling is desired, you may wish to recirculate
interior air by pressing the recirculation control button. The
recirculation indicator will illuminate when this button is
selected. Press the button a second time to turn off the
Recirculation mode and allow outside air into the vehicle.
NOTE:In cold weather, use of recirculation mode may lead
to excessive window fogging. On systems with Manual
Climate Controls, the recirculation mode is not allowed in
Defrost mode to improve window clearing operation.
Recirculation will be disabled automatically if this mode is
selected. Attempting to use recirculation while in this
mode will cause the LED in the control button to blink and
then turn off.
Operating Tips
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended. Refer
to “Fluids and Lubricants” in “Technical Specifications” for
proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Refer to “Dealer Service” in “Servicing
And Maintenance” for proper coolant selection. Use of the
air recirculation mode during Winter months is not recom-
mended because it may cause window fogging.
Vacation/Storage
Any time 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 fresh air
with the blower setting on high. This will ensure adequate
system lubrication to minimize the possibility of compres-
sor damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost on
the inside of the glass in very cold weather. To clear the
windows, select Defrost or Mix mode and increase the
front blower speed. Do not use the Recirculation mode
without A/C for long periods, as fogging may occur.

3. Temperature Gauge•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather or up mountain
grades. It should not be allowed to exceed the upper
limits of the normal operating range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Servicing And Mainte-
nance.” Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H,”

pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H,” turn the engine off immediately and call an
authorized dealer for service.
4. Tachometer •Indicates the engine speed in revolutions per minute
(RPM x 1000).
5. Instrument Cluster Display •When the appropriate conditions exist, this display
shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
INSTRUMENT CLUSTER DISPLAY
Your vehicle may be equipped with an instrument cluster
display, which offers useful information to the driver. With
the ignition in the STOP/OFF mode, opening/closing of a
door will activate the display for viewing, and display the
total miles, or kilometers, in the odometer. Your instrument

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
— Battery Charge Warning Light
This light illuminates when the battery is not charging
properly. If it stays on while the engine is running, there
may be a malfunction with the charging system. Contact
your authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.
— Door Open Warning Light
This indicator will illuminate when one or more door(s) are
not fully closed.
NOTE: If the vehicle is moving and a door is opened, there
will also be a single chime.
— Electronic Throttle Control (ETC) Warning
Light
This light informs you of a problem with the Electronic
Throttle Control (ETC) system. If a problem is detected
while the vehicle is running, the light will either stay on or flash depending on the nature of the problem. Cycle the
ignition when the vehicle is safely and completely stopped
and the transmission is placed in the PARK position. The
light should turn off. If the light remains on with the
vehicle running, your vehicle will usually be drivable;
however, see an authorized dealer for service as soon as
possible.
If the light continues to flash when the vehicle is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is placed in the ON/RUN or
MAR/ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.
— Engine Coolant Temperature Warning Light
This light warns of an overheated engine condition. If the
engine coolant temperature is too high, this indicator will
illuminate and a single chime will sound. If the tempera-
ture reaches the upper limit, a continuous chime will be
sound for four minutes or until the engine is able to cool:
whichever comes first.
If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift

the transmission into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal, turn the
engine off immediately and call for service. Refer to “If
Your Engine Overheats” in “In Case Of Emergency” for
further information.
— Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light
turns on while driving, stop the vehicle and shut off the
engine as soon as possible. A chime will sound when this
light turns on.
Do not operate the vehicle until the cause is corrected. This
light does not indicate how much oil is in the engine. The
engine oil level must be checked under the hood.
— Transmission Temperature Warning Light — If
Equipped
This light indicates high transmission fluid temperature.
This may occur with strenuous usage such as trailer
towing. If this light turns on, stop the vehicle and run the
engine at idle or slightly faster, with the transmission in
PARK or NEUTRAL, until the light turns off. Once the light
turns off, you may continue to drive normally.
WARNING!
If you continue operating the vehicle when the Trans-
mission Temperature Warning Light is illuminated you
could cause the fluid to boil over, come in contact with
hot engine or exhaust components and cause a fire.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Warning Light illuminated will eventually cause
severe transmission damage or transmission failure.
— Seat Belt Reminder Warning Light
When the ignition is first placed in the ON/RUN or
MAR/ON/RUN position, if the driver ’s seat belt is un-
buckled, a chime will sound and the light will turn on.
When driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Reminder Light will flash
or remain on continuously and a chime will sound. Refer to
“Occupant Restraints Systems” in “Safety” for further
information.

Refer to “Recreational Towing” in “Starting And Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the Electronic Range Select
(ERS) shift control (refer to “Electronic Range Select (ERS)
Operation” in this section for further information) to select
a lower gear range. Under these conditions, using a lower
gear range will improve performance and extend transmis-
sion life by reducing excessive shifting and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the transmis-
sion shift schedule, reduce engine torque, and/or expand the
range of torque converter clutch engagement. This is done to
prevent transmission damage due to overheating.
If the transmission becomes extremely hot, the “Transmis-
sion Temperature Warning Light” may illuminate and the
transmission may operate differently until the transmission
cools down.
During cold temperatures, transmission operation may be
modified depending on engine and transmission tempera-
ture as well as vehicle speed. This feature improves warm
up time of the engine and transmission to achieve maxi-
mum efficiency. Engagement of the torque converter
clutch, and shifts into 8th or 9th gear, are inhibited until the
transmission fluid is warm (refer to the “Note” under
“Torque Converter Clutch” in this section). Normal opera-
tion will resume once the transmission temperature has
risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for abnor-
mal conditions. If a condition is detected that could result in
transmission damage, Transmission Limp Home Mode is
activated. In this mode, the transmission may operate only in

Speed Control — If Equipped
•Do not use on hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.

5. Insert a small screwdriver or a similar tool into the gearselector override access hole (at the right front corner of
the gear selector assembly), then push and hold the
override release lever down. While holding the override
release lever down, push the lock button on the gear
selector and move the gear selector to the NEUTRAL
position.
6. The vehicle may then be started in NEUTRAL.
7. Reinstall the gear selector boot.IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase the engine idle speed
while preventing vehicle motion with the brakes.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you

WARNING!(Continued)
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on HOT
(H), and you hear continuous chimes, turn the engine
off immediately and call for service.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Push and hold the lock button on the gear selector.
Then shift back and forth between DRIVE and REVERSE,
while gently pressing the accelerator. Use the least amount of accelerator pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing the engine.
NOTE:
Shifts between DRIVE and REVERSE can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL for more
than two seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission 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 prolonged efforts to
free a stuck vehicle.
NOTE: Push the ESC Off switch, to place the Electronic
Stability Control (ESC) system in Partial Offmode, before
rocking the vehicle. Refer to “Electronic Brake Control
System” in “Safety” for further information. Once the
vehicle has been freed, push the ESC Offswitch again to
restore ESC On mode.7

WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle’s wheels
faster than 30 mph (48 km/h) or for longer than 30
seconds continuously without stopping when you are
stuck and do not let anyone near a spinning wheel, no
matter what the speed.
CAUTION!
•When “rocking” a stuck vehicle by shifting between
DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.
• Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure. It
can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmis-
sion shifting occurring).
