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.
CAUTION: (Continued)
CAUTION: (Continued)
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 ªPulling
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.
If you cannot shift out of PARK (P), ease pressure on
the shift lever
-- push the shift lever all the way into
PARK (P) as you maintain brake application. Then
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 key to the OFF ignition position.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear you want.
5. Take your vehicle to an authorized service center 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.

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.

When the DRL are on, only your high-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps won't be on. Your instrument panel
lights won't be on either.
When it is dark enough outside, your low
-beam
headlamps will come on. The other lamps that turn on
with your headlamps will also turn on. When it is bright
enough outside, the regular lamps will go off, and your
high
-beam headlamps change to the reduced brightness
of DRL.
To turn off all exterior lighting at night when you are
parked, turn off the headlamps and move the twilight
sentinel control all the way toward MIN. The exterior
lamps will turn back on automatically when you move
the transaxle out of PARK (P).
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Cornering Lamps (If Equipped)
The cornering lamps are designed to turn on when you
signal a turn. This will provide more lighting when
cornering at night.
Twilight Sentinel
Twilight sentinel turns your
lamps on and off by sensing
how dark it is outside.
To operate it, leave the lamp switch off.
If you move the control all the way to MAX, your
headlamps will remain on for three minutes after you
turn off your engine. As you move the control toward
MIN, the headlamps will turn off more quickly when
you turn off your engine. You can change this delay time
from only a few seconds to three minutes.

2-43 Illuminated Entry (If Equipped)
Press the UNLOCK button on the remote keyless entry
transmitter (if equipped) and the interior courtesy lamps
will turn on and stay on for up to one minute. The lamps
will turn off immediately by pressing the LOCK button
on the remote keyless entry transmitter, starting the
engine or activating the power door locks.
Delayed Entry Lighting
When you open the door, the interior lamps will turn on.
When you close the door with the ignition off, the
interior lamps will stay on for 25 seconds or until the
ignition is turned to an on position. Note that locking the
doors will override the delayed entry lighting feature
and the lamps will turn off right away.
Theater Dimming
This feature allows for a three to five-second fade out of
the courtesy lamps instead of immediate turn off.
Delayed Exit Lighting
With this feature, the interior lamps will turn on and stay
on for up to 25 seconds after you remove the key from
the ignition. This will give you time to find the door pull
handle or lock switches.
Perimeter Lighting (If Equipped)
When the UNLOCK button on the remote keyless entry
transmitter is pressed, the headlamps, parking lamps,
back
-up lamps and cornering lamps will turn on if it is
dark enough outside according to the twilight sentinel.
If your vehicle is not equipped with twilight sentinel
and perimeter lighting is active, the lights will turn on
whenever the UNLOCK button on the transmitter
is pressed.
Personal Choice Programming
This feature can be programmed in the on or off mode
for each transmitter.
To turn the feature off:
1. Turn the ignition key to OFF.
2. Press and hold LOCK on the power door lock switch
throughout this procedure. All the doors will lock.
3. Press the instant alarm on the remote keyless entry
transmitter. Perimeter lighting remains on at this
time and the horn will chirp two times.

2-58 Speedometer and 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. If you see
bright silver lines between the numbers, you'll know
that someone has probably tried to turn it back. The
numbers may not be true.
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 it must be. But 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.
Trip Odometer
A trip odometer can tell you how far you have driven
since you last set it to zero. To reset it, push the button.
Tachometer (If Equipped)
The tachometer tells you
how fast the engine is
going. It displays engine
speed in thousands
of revolutions per
minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the red area or engine damage may occur.

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.

2-60 Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks the
air bag's electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see ªAir
Bagº in the Index.
This light will come on
when you start your engine,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Battery System Warning Light
Standard Cluster Gage Cluster
When you turn the key to RUN, one of these lights will
turn on briefly to show that your generator and battery
charging systems are working.
If the light stays on, you need service and you should
take your vehicle to the dealer at once. To save your
battery until you get there, turn off all accessories and
set your climate control system to OFF.
