•To program the two remaining HomeLink® buttons,
repeat each step for each remaining button. DO NOT
erase the channels.
Reprogramming A Single HomeLink® Button
(Non-Rolling Code)
To reprogram a channel that has been previously trained,
follow these steps:
1. Cycle the ignition to the ON/RUN position.
2. Push and hold the desired HomeLink® button until
the indicator light begins to flash after 20 seconds.Do
not release the button.
3.Without releasing the buttonproceed with “Program-
ming A Non-Rolling Code” step 2 and follow all
remaining steps.
Canadian/Gate Operator Programming
For programming transmitters in Canada/United States
that require the transmitter signals to “time-out” after
several seconds of transmission.
Canadian radio frequency laws require transmitter sig-
nals to time-out (or quit) after several seconds of trans-
mission – which may not be long enough for HomeLink®
to 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.
1. Cycle the ignition to the ON/RUN position.

12. Tachometer
The white area of the scale shows the permissible engine
revolutions-per-minute (RPM x 1000) for each gear range.
Before reaching the red area, ease up on the accelerator to
prevent engine damage.
13. Engine Temperature Warning Light
This light warns of an overheated engine condition. As
engine coolant temperatures rise and the gauge ap-
proachesH, this indicator will illuminate, and a single
chime will sound after reaching a set threshold. Further
overheating will cause the temperature gauge to passH,
a continuous chime will occur until the engine is allowed
to cool or the four minutes duration is expired, which-
ever come 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 ve-
hicle. 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 “What To
Do In Emergencies” for further information.
14. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake

•Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
Mode by pushing the Recirculation button. However,
under certain conditions, while in Automatic Mode,
the system is blowing air out the defrost vents. When
these conditions are present, and the Recirculation
button is pushed, the indicator will flash and then turn
off. This tells you that you are unable to go into
Recirculation Mode at this time. If you would like the
system to go into Recirculation Mode, you must first
move the Mode knob to Panel, Bi-Level, Mix, or Floor
and then push the Recirculation button. This feature
reduces the possibility of window fogging.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheating.
A solution of 50% OAT (Organic Additive Technology)
coolant that meets the requirements of Chrysler Material
Standard MS.90032 and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation Mode during winter months is
not recommended because it may cause window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

If the transmission temperature exceeds normal operat-
ing limits, the transmission controller will modify the
transmission shift schedule and 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 “Transmission
Temperature Warning Light” may illuminate and the
transmission may operate differently until the transmis-
sion cools down.
During very cold temperatures (-4°F [-20°C] or below),
transmission operation may be modified depending on
engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal 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 fourth gear regardless of which forward gear is
selected. PARK, REVERSE, and NEUTRAL will continue
to operate. The Malfunction Indicator Light (MIL) may be
illuminated. Limp Home Mode allows the vehicle to be
driven to an authorized dealer for service without dam-
aging the transmission.
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 switch to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.

this happens, the transmission overheat indicator light
will come on, and the vehicle will slow slightly until the
transmission cools down enough to allow a return to the
requested speed. This is done to prevent transmission
damage due to overheating. If the high speed is main-
tained, the overheating may reoccur, as before, in a cyclic
fashion.
LOW (L) — If Equipped
Use this range for engine braking when descending very
steep grades. In this range, the transmission will down-
shift for maximum engine braking, and upshifts will
occur only to prevent engine overspeed.
AUTOSTICK
Autostick (Six-Speed Automatic Transmission)
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Operation
When the shift lever is in the DRIVE position, the
transmission will operate automatically, shifting between
the six available gears. To engage AutoStick, simply tap
the shift lever to the right or left (+/-) while in the DRIVE
position. Tapping (-) to enter AutoStick mode will down-
shift the transmission to the next lower gear, while using
(+) to enter AutoStick mode will retain the current gear.
When AutoStick is active, the current transmission gear is
displayed in the instrument cluster.
In AutoStick mode, the transmission will shift up or
down when the driver moves the shift lever to the right
(+) or left (-), unless an engine lugging or overspeed

WARNING!
Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary areas
are affected by improper tire pressure:
•Safety and Vehicle Stability
•Economy
•Tread Wear
•Ride Comfort
Safety
WARNING!
•Improperly inflated tires are dangerous and can
cause collisions.
•Under-inflation increases tire flexing and can re-
sult in overheating and tire failure.
•Over-inflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can
cause damage that result in tire failure.
•Overinflated or under-inflated tires can affect ve-
hicle handling and can fail suddenly, resulting in
loss of vehicle control.
•Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
instrument panel, below the radio.
Push the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Push the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE:With extended use the Hazard Warning flashers
may wear 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, 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.

and REVERSE (with automatic transmission) or 2nd gear
and REVERSE (with manual transmission), while gently
pushing the accelerator. Use the least amount of accelera-
tor pedal pressure that will maintain the rocking motion,
without spinning the wheels, or racing the engine.
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 clutch or 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 Off#mode,
before rocking the vehicle. Refer to “Electronic Brake
Control” in “Starting And Operating” for further infor-
mation. Once the vehicle has been freed, push the#ESC
Off#switch again to restore#ESC On#mode.
CAUTION!
•When “rocking” a stuck vehicle by shifting be-
tween DRIVE/2nd 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 trans-
mission shifting occurring).

WHAT TO DO IN EMERGENCIES 467

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.
NOTE:Intentional tampering with emissions control
systems 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 specifica-
tions, should be obtained immediately.
To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
