Leaving Your Vehicle With the
Engine Running
CAUTION:
It can be dangerous to leave your vehicle with the
engine running. Your vehicle could move
suddenly if the shift lever is not fully in PARK (P)
with the parking brake firmly set. And, if you
leave the vehicle with the engine running, it could
overheat and even catch fire. You or others could
be injured. Don't leave your vehicle with the
engine running unless you have to.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you've moved the shift lever into PARK (P), hold the
regular brake pedal down. Then, see if you can move the
shift lever away from PARK (P) without first pulling it
toward you. If you can, it means that the shift lever
wasn't fully locked into PARK (P).
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).

2-56
Shifting Out of PARK (P)
Your vehicle has an automatic transaxle shift lock
control system. You have to fully apply your regular
brakes before you can shift from PARK (P), when the
ignition is in RUN.
As you step on the brake pedal, while in PARK (P), you
may hear a click from the solenoid of the system. This
ensures that the system is operating properly. See
ªAutomatic Transaxle Operationº in the Index.If you cannot shift out of PARK (P), ease pressure on
the shift lever by pushing it all the way into PARK (P)
as you maintain brake application. Then try to move the
shift lever into the gear you want. If you ever hold the
brake pedal down but still can't shift out of PARK (P),
try this:
1. Turn the ignition key to OFF.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the engine and then shift to the drive gear
you want.
5. Have the vehicle fixed as soon as you can.

Parking Over Things That Burn
CAUTION:
Things that can burn could touch hot exhaust
parts under your vehicle and ignite. Don't park
over papers, leaves, dry grass or other things that
can burn.
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.

2-58
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 Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the 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.
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're pulling a trailer, see ªTowing a Trailerº in
the Index.
Horn
You can sound the horn by pressing the horn symbols on
your steering wheel.

Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Decide which one of the three channels (one of the
HomeLink buttons) you want to program.
2. Press and hold the desired button on HomeLink
through Step 3.
3. When the HomeLink indicator light begins to blink
slowly (this may take up to 30 seconds), hold the
hand
-held transmitter about 1 to 3 inches (3 to 8 cm)
away from HomeLink and then press and hold the
transmit button on the hand
-held transmitter.
Continue to hold both buttons until the indicator
light on HomeLink begins to flash rapidly (this may
take up to 90 seconds).If you have trouble programming HomeLink, make
sure that you have followed the directions exactly as
described and that the battery in the hand
-held
transmitter is not weak. If you still cannot program it,
move the hand
-held transmitter to the left or right or
forward or backward or flip it upside down. HomeLink
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 ªTraining a Garage Door Opener with
a ªRolling Codeº Featureº later in this section or contact
the manufacturer of HomeLink at 1
-800-355-3515, or
on the internet at www.homelink.com.
Be sure to keep the original hand
-held transmitter
in case you need to erase and reprogram the
HomeLink Transmitter.

Speedometer and Tamper
Resistant Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). Your
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used in Canada).
Your vehicle has a tamper
-resistant odometer.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
If it can't, then it's set at zero and a label must be put on
the driver's door to show the old mileage reading when
the new odometer was installed.
Dual Trip Odometers
In addition to the standard odometer, the cluster can also
display two separate trip odometers (designated by the
letter A or B in the display window) as well as your
vehicle's Engine Oil Life (designated by the word OIL
in the display window). The display can be toggled
between the odometer, the trip odometers and engine
oil life by quickly pressing and releasing the trip/reset
button located to the right of the temperature gage.
The display toggles once each time the trip/reset button
is pressed for less than 1.5 seconds. The display toggles
in the following sequence: Odometer
- Trip
Odometer A
- Trip Odometer B - Engine Oil Life.
If the engine oil life is left on the display, it will
automatically toggle back to the odometer after
approximately 15 seconds. Each of the two trip
odometers can be used to keep track of different trip
distances (for example, the mileage of a long trip
and the mileage driven on the current tank of fuel).
The trip odometers will continue to keep track of miles
(kilometers) driven even if they are not currently
displayed. To reset the odometer to zero (0), press and
hold the trip/reset button for at least 1.5 seconds, but less
than three seconds. Only the trip odometer that is
showing in the display will be reset.

2-102
Retro-Active Reset
Each of the two trip odometers has a feature called
retro
-active reset. This feature can be used to set either
(or both) trip odometer(s) to the number of miles
(kilometers) driven since the ignition was last turned on.
This can be used if you forget to reset your trip
odometer at the beginning of a trip. To use the
retro
-active reset feature, press and hold the trip/reset
button for at least three seconds. The trip odometer will
then display the number of miles (kilometers) driven
since the ignition was last turned on and you began
driving. (If you use the retro
-active reset feature after
you have started the vehicle, but before you begin
moving, the display will show the number of miles
(kilometers) you drove during the last ignition cycle.)
Once you begin driving, the trip odometer will
accumulate mileage. For example, if you have driven
5.0 miles (8.0 km) since you started your vehicle, and
then activate the retro
-active reset feature, the display
will show 5.0 miles (8.0 km). As you drive, the display
will then increase to 5.1 miles (8.2 km), 5.2 miles
(8.4 km), etc. Only the trip odometer that is displayed
will be affected by the retro
-active reset so that both trip
odometers can be used separately.
Warning Lights, Gages, Messages
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.
