Shifting Out of Park (P)
(Automatic Transmission)
Your vehicle has an automatic transmission shift
lock control system. You have to apply your
regular brake before you can shift from PARK (P)
when the ignition is in ON. SeeAutomatic
Transmission Operation on page 106.
If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the way
into PARK (P) as you maintain brake application.
Then move the shift lever into the gear you wish.
Press the shift lever button before moving the
shift lever.
Parking Your Vehicle
(Manual Transmission)
Your vehicle has a manual transmission. Before
you get out of your vehicle, move the shift
lever into REVERSE (R), and rmly apply the
parking brake. Once the shift lever has been
placed into REVERSE (R) with the clutch pedal
pressed in, turn the ignition key to LOCK, remove
the key and release the clutch.
If you are parking on a hill, or if your vehicle is
pulling a trailer, seeTowing a Trailer on page 297.
Parking Over Things That Burn
{CAUTION:
Things that can burn could touch hot
exhaust parts under your vehicle and
ignite. Do not park over papers, leaves,
dry grass, or other things that can burn.
119

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 120.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is at
the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park in
a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 281.
{CAUTION:
It can be dangerous to get out of your
vehicle if the automatic transmission shift
lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can
roll. Do not leave your vehicle when the
engine is running unless you have to. If
you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle
will not move, even when it is on fairly
level ground, always set the parking brake
and move the automatic transmission
shift lever to PARK (P), or the manual
transmission shift lever to NEUTRAL.
Follow the proper steps to be sure your vehicle will
not move. SeeShifting Into Park (P) (Automatic
Transmission) on page 117andParking Your
Vehicle (Manual Transmission) on page 119.
If you are pulling a trailer with your vehicle, see
Towing a Trailer on page 297.

If you have a newer garage door opener with rolling
codes, please be sure to follow Steps 6 through 8 to
complete the programming of your Universal Home
Remote Transmitter.
Read the instructions completely before attempting
to program the Universal Home Remote.
Because of the steps involved, it may be helpful to
have another person available to assist you in
the programming steps.
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal
Home Remote programming. It is also
recommended that upon the sale of the vehicle,
the programmed Universal Home Remote buttons
should be erased for security purposes. See
“Erasing Universal Home Remote Buttons” later in
this section or, for assistance, seeCustomer
Assistance Offices on page 452.
Be sure that people and objects are clear of the
garage door or gate operator you are
programming. When programming a garage door,
it is advised to park outside of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.Programming Universal Home Remote
Follow these steps to program up to three
channels:
1. Press and hold down the two outside
Universal Home Remote buttons, releasing
only when the Universal Home Remote
indicator light begins to ash, after
20 seconds. Do not hold down the buttons for
longer than 30 seconds and do not repeat
this step to program a second and/or
third hand-held transmitter to the remaining
two Universal Home Remote buttons.
2. Position the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from the
Universal Home Remote buttons while
keeping the indicator light in view.
3. Simultaneously press and hold both the
desired Universal Home Remote button
and the hand-held transmitter button. Do not
release the buttons until Step 4 has been
completed.
Some entry gates and garage door openers
may require you to substitute Step 3 with
the procedure noted in “Gate Operator and
Canadian Programming” later in this section.
140

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to time out or quit after several seconds
of transmission. This may not be long enough
for Universal Home Remote to pick up the signal
during programming. Similarly, some U.S. gate
operators are manufactured to time out in
the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator or garage door
opener by using the “Programming Universal
Home Remote” procedures, regardless of where
you live, replace Step 3 under “Programming
Universal Home Remote” with the following:
Continue to press and hold the Universal Home
Remote button while you press and release every
two seconds (cycle) the hand-held transmitter
button until the frequency signal has been
successfully accepted by the Universal Home
Remote. The Universal Home Remote indicator
light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming
Universal Home Remote” to complete.
Using Universal Home Remote
Press and hold the appropriate Universal Home
Remote button for at least half of a second.
The indicator light will come on while the signal is
being transmitted.
Erasing Universal Home Remote
Buttons
To erase programming from the three Universal
Home Remote buttons do the following:
1. Press and hold down the two outside buttons
until the indicator light begins to ash, after
20 seconds. Do not hold the two outside
buttons for longer than 30 seconds.
2. Release both buttons.
The Universal Home Remote is now in the training
(learning) mode and can be programmed at any
time beginning with Step 2 under “Programming
Universal Home Remote” shown earlier in
this section.
Individual buttons cannot be erased, but they can
be reprogrammed. See “Reprogramming a
Single Universal Home Remote Button” following
this section.

Using Cruise Control on Hills
How well your cruise control works on hills depends
upon your speed, load, and the steepness of the
hills. When going up steep hills, you might want
to step on the accelerator pedal to maintain the
vehicle speed. When going downhill, you might
have to brake or shift to a lower gear to keep the
vehicle speed down. Of course, applying the brake
turns off the cruise control. Many drivers nd this
to be too much trouble and do not use cruise control
on steep hills.
Ending Cruise Control
To turn off the cruise control, do one of the following:
Step lightly on the brake pedal.
Move the cruise control switch to off.
Lightly tap or press the clutch, if you have
a manual transmission.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
the cruise control set speed memory is erased.
Exterior Lamps
The control on the driver’s side of your instrument
panel operates the exterior lamps.
O(Exterior Lamps):Turn the knob, located to
the right of this symbol, to choose one of the
four exterior lamp positions.
