3. When the system is set up for your comfort level, it isnot necessary to change the settings. You experience the
greatest efficiency by simply allowing the system to
function automatically.
NOTE:
• It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode, and blower speed to provide
comfort as quickly as possible.
• The temperature can be displayed in U.S. or Metric units
by selecting the US/Metric customer-programmable fea-
ture.
To provide you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan remains on low
until the engine warms up. The blower increases in speed
and transition into Auto mode.Manual Operation Override
This system offers a full complement of manual override
features. The AUTO symbol in the front ATC display will
be turned off when the system is being used in the manual
mode.
NOTE: The system will not automatically sense the pres-
ence of fog, mist or ice on the windshield. Defrost mode
must be manually selected to clear the windshield and side
glass.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
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.

grades. It should not be allowed to exceed the upper
limits of the normal operating range.
WARNING!
•Driving with a hot engine cooling system could
damage 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.
• 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
Maintenance.” Follow the warnings under the Cool-
ing System Pressure Cap paragraph.

WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
— Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to indicate 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.
NOTE: This light may turn on if the accelerator and brake
pedals are pressed at the same time.
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
ACC/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 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.
— Hood Open Warning Light — If Equipped
This warning light will illuminate when the hood is left
open and not fully closed.
88 GETTING TO KNOW YOUR INSTRUMENT PANEL

When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, or traveling into strong head winds), use the
AutoStick shift control (refer to AutoStick in this section for
further information) to select a lower gear. Under these
conditions, using a lower gear will improve performance
and extend transmission life by reducing excessive shifting
and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller will expand the range of
torque converter clutch engagement. This is done to pre-
vent transmission damage due to overheating.
During cold temperatures, transmission operation may be
modified depending on engine coolant temperature. Nor-
mal operation will resume once the engine temperature has
risen to a suitable level.
Instrument Cluster Messages
Dedicated messages will be displayed in the instrument
cluster to alert the driver when certain unusual conditions
occur.Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission remains
in a fixed gear regardless of which forward gear is selected.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home Mode allows the vehicle to be driven to an
authorized dealer for service without damaging the trans-
mission.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is nolonger detected, the transmission will return to normal
operation.

STARTING AND OPERATING 173

•Avoid using speed control when AutoStick is engaged
because the transmission will not shift automatically.
• Transmission shifting will be more noticeable when
AutoStick is enabled.
• The system may revert to automatic shift mode if a fault
or overheat condition is detected.
To disengage AutoStick mode, return the gear selector to
the DRIVE position. You can shift in or out of the AutoStick
position at any time without taking your foot off the
accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.
SPORT MODE
The Sport mode increases steering feedback to the driver
with slight increases in effort and throttle pedal-to-engine
response. Changes to the transmission shift schedules for
more aggressive shifting will occur on automatic transmis-
sion versions.
Sport driving mode is useful while driving on winding
roads where more steering precision is desired.

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 engine idle speed.
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
see or hear steam coming from under the hood, do not

WARNING! (Continued)
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 pointer rises to the H (red) mark, the
instrument cluster will sound a chime. When safe, pull
over and stop the vehicle with the engine at idle. Turn
off the air conditioning and wait until the pointer
drops back into the normal range. If the pointer
remains on the H (red) mark for more than a minute,
turn the engine off immediately and call for service.
GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector cannot be
moved out of the PARK position, you can use the following
procedure to temporarily move the gear selector:
1. Turn the engine OFF.
2. Firmly apply the parking brake.
216 IN CASE OF EMERGENCY

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!
•Racing the engine or spinning the wheels may lead
to transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL
(Continued)
CAUTION! (Continued)
for at least one minute after every five rocking-
motion cycles. This will minimize overheating and
reduce the risk of clutch or transmission failure
during prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shifting between
DRIVE/SECOND GEAR and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train 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).
218 IN CASE OF EMERGENCY

Exhaust System
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, have the exhaust
system inspected each time the vehicle is raised for lubri-
cation or oil change. Replace as required.
WARNING!
•Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to “Safety Tips” in “Safety” for further information.
• A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be

WARNING! (Continued)
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.
CAUTION!
•The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective-
ness of the catalyst as an emissions control device
and may seriously reduce engine performance and
cause serious damage to the engine.
• 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.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
8
SERVICING AND MAINTENANCE 241

keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE:Intentional tampering with emissions control sys-
tems can result in civil penalties being assessed against
you.
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 tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not interrupt the ignition when the transmission is in
gear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the
vehicle.
• Do not idle the engine with any ignition components
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.Cooling System
WARNING!
• You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never open a cooling system pressure cap
when the radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised. The
fan starts automatically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling fan, discon-
nect the fan motor lead or turn the ignition to the
OFF mode. The fan is temperature controlled and can
start at any time the ignition is in the ON mode.
Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty or rusty in
appearance, the system should be drained, flushed and
refilled with fresh engine coolant (antifreeze). Check the
front of the A/C condenser for any accumulation of bugs,
