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 button proceed 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.

UNDERSTANDING THE FEATURES OF YOUR VEHICLE 287

Manual Operation Override
The system allows for manual selection of blower speed,
air distribution mode, A/C status and recirculation con-
trol.
The blower fan speed can be set to any fixed speed by
adjusting the blower control. The fan will now operate at
a fixed speed until additional speeds are selected. This
allows the front occupants to control the volume of air
circulated in the vehicle and cancel the Auto mode.
The operator can also select the direction of the airflow
by selecting one of the available mode settings. A/C
operation and Recirculation control can also be manually
selected in Manual operation.
NOTE:Each of these features operates independently
from each other. If any feature is controlled manually,
temperature control will continue to operate automati-
cally.
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 FCA 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.

CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, orwhile 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 transmission life by reducing excessive shifting
and heat buildup.
If the transmission temperature exceeds normal operat-
ing limits, the transmission controller may modify the
transmission shift schedule, reduce engine torque,
and/or expand the range of torque converter clutch
engagement. This is done to prevent transmission dam-
age due to overheating.
If the transmission becomes extremely hot, the “Trans-
mission Temperature Warning Light” may illuminate and
the transmission may operate differently until the trans-
mission cools down.

STARTING AND OPERATING 491

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.
• Underinflation increases tire flexing and can result
in overheating and tire failure.
• Overinflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can
cause damage that result in tire failure.
• Overinflated or underinflated 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.

552 STARTING AND OPERATING

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located in the
switch bank below the radio screen.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 your engine by taking the
appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, put transmission in
NEUTRAL, but do not increase engine idle speed.
CAUTION!
Driving with a hot 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” and you hear continuous chimes, turn the
engine off immediately and call for service.

WHAT TO DO IN EMERGENCIES 617

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 push the brake pedal
to engage DRIVE or REVERSE.
Use the least amount of accelerator 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
engine 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 pro-
longed efforts to free a stuck vehicle.
(Continued)
CAUTION! (Continued)
•When “rocking” a stuck vehicle by shifting be-
tween 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 trans-
mission shifting occurring).
NOTE: Push the “ESC Off” switch (if necessary), to place
the Electronic Stability Control (ESC) system in “Partial
Off” mode, before rocking the vehicle. Refer to “Elec-
tronic Brake Control” in “Starting And Operating” for
further information. Once the vehicle has been freed,
push the ESC Off switch again to restore “ESC On”
mode.

WHAT TO DO IN EMERGENCIES 649

CAUTION!
•The catalytic converter requires the use of un-
leaded fuel only. Leaded gasoline will destroy the
effectiveness of the catalyst as an emissions control
device and may seriously reduce engine perfor-
mance 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
involving engine misfire or other apparent loss of
performance, have your vehicle serviced promptly.
Continued 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 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.
