2-30 Torque Lock
If you are parking on a hill and you don't shift your
transaxle into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in
the transaxle. You may find it difficult to pull the shift
lever out of PARK (P). This is called ªtorque lock.º To
prevent torque lock, set the parking brake and then shift
into PARK (P) properly before you leave the driver's
seat. To find out how, see ªShifting Into PARK (P)º in
the Index.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transaxle, so you
can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
CAUTION:
Before shifting out of PARK (P) you must fully
apply your regular brakes. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. If you're pulling a trailer, see ªTowing
a Trailerº in the Index,
Your vehicle has a Brake-Transaxle Shift Interlock
(BTSI). You have to fully apply your regular brake
before you can shift from PARK (P) when the ignition is
in RUN. See ªAutomatic Transaxleº in the Index.

Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving
over high points on the road or over
road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.
Running Your Engine While
You're Parked
It's 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 under
ªEngine Exhaustº).
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan switch 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.
(See ªBlizzardº in the Index.)

CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you've left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won't move, even when you're on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle won't
move. See ªShifting Into PARK (P)º in the Index.
If you are parking on a hill and if you're pulling a
trailer, also see ªTowing a Trailerº in the Index.
Windows
Power Windows
Switches on the driver's armrest control each of the
windows while the ignition is on or retained accessory
power is active. In addition, the passenger's door
armrest has a switch for its own window.
To lower the passenger's window, pull back on the right
switch. The window will lower as long as the switch is
held. To raise either window, push the switch forward.

To idle your vehicle with the DRL off, shift the
transaxle into PARK (P). The DRL will stay off until
you shift out of PARK (P).
To turn off all exterior lamps at night when you are in
PARK (P), turn off the headlamps and move the twilight
sentinel control, located on the lower area of the
headlamp switch, all the way toward AUTO MIN. When
released, the spring control will return to the twilight
sentinel minimum delay position, and all exterior lamps
will turn off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps (Option)
The cornering lamps are designed to come on when you
signal a turn. This will provide more light for cornering
at night.
Twilight Sentinel

Twilight sentinel turns your headlamps, taillamps and
parking lamps on and off by sensing how dark it is
outside. The control is located on the lower area of the
headlamp switch.To operate this feature, leave the headlamp switch off.
The vehicle's twilight sentinel is always enabled.
Twenty
-three seconds after entering a darkened
environment, the headlamps and parking lamps will turn
on. If the ignition is turned on at night, the exterior
lamps will come on.
To turn off all exterior lamps at night when you are in
PARK (P), turn off the headlamps and move the twilight
sentinel control, located on the lower area of the
headlamp switch, all the way toward AUTO MIN. When
released, the spring control will return to the twilight
sentinel minimum delay position, and all exterior lamps
will turn off.
If you move the control all the way to AUTO MAX,
your lamps will remain on for three minutes after you
turn off your engine. If you move the control toward
AUTO MIN, the lamps will go off quickly when you
turn off your engine. You can set this delay time for only
a few seconds or up to three minutes.
Light Sensor
Your twilight sentinel and daytime running lamps work
with the light sensor on top of the instrument panel.
Don't cover it up. If you do, it will read ªdarkº and the
headlamps will come on.

Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the Universal Transmitter
until the indicator light begins to flash rapidly (after
20 seconds). Then release the buttons. This
procedure initializes the memory and erases any
previous settings for all three channels.
2. Decide which one of the three channels you want to
program. Hold the end of the hand
-held transmitter
about 2 to 5 inches (5 to 13 cm) away from the
surface of the Universal Transmitter so that you can
still see the indicator light.
3. Using both hands, press the hand
-held transmitter
button and the desired button on the Universal
Transmitter. Continue to press both buttons
through Step 4.
4. Hold down both buttons until you see the indicator
light on the Universal Transmitter flash slowly and
then rapidly. The rapid flashing indicates that the
Universal Transmitter has been programmed.
Release both buttons once the indicator light starts to
flash rapidly.If you have trouble programming the Universal
Transmitter, make sure that you have followed the
directions exactly as described. The Universal
Transmitter may not work with older garage door
openers that do not meet current Federal Consumer
Safety Standards. If you cannot program the transmitter
after repeated attempts, refer to ªRolling Codes
Programmingº later in this section or contact the
Universal Transmitter manufacturer at 1
-800-355-3515.
Be sure to keep the original hand
-held transmitter
in case you need to erase and reprogram the
Universal Transmitter.
Note to Canadian Owners: During programming, the
hand
-held transmitter may automatically stop
transmitting after one or two seconds. In this case, you
should press and re
-press the button on the hand-held
transmitter every two seconds without ever releasing the
button on the Universal Transmitter. Release both
buttons when the indicator light on the Universal
Transmitter begins to flash rapidly.

Warning Lights, Gages
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or
others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle's functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they're working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
there's a problem with your vehicle.When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual's advice.
Waiting to do repairs can be costly
-- and even
dangerous. So please get to know your warning lights
and gages. They're a big help.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts.
The safety belt light will
also come on and stay on
for about 70 seconds. If the
driver's belt is already
buckled, neither the chime
nor the light will come on.
