Ensure the shift lever is fully in PARK (P) before
starting the engine. 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 key is in RUN. 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 wish. See ªShifting Out of
PARK (P)º in the Index.
REVERSE (R): Use this gear to back up.
NOTICE:
Shifting to REVERSE (R) while your vehicle is
moving forward could damage your transaxle.
Shift to REVERSE (R) only after your vehicle
is stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transaxle, see
ªStuck: In Sand, Mud, Ice or Snowº in the Index.NEUTRAL (N): In this position, your engine
doesn't connect with the wheels. To restart when you're
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
CAUTION:
Shifting out of PARK (P) or NEUTRAL (N) while
your engine is ªracingº (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people or
objects. Don't shift out of PARK (P) or
NEUTRAL (N) while your engine is racing.
NOTICE:
Damage to your transaxle caused by shifting out
of PARK (P) or NEUTRAL (N) with the engine
racing isn't covered by your warranty.

2-32
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).

2-33
Shifting Out of PARK (P)
Your vehicle has an automatic transaxle shift lock control
system. 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 OFF. Open and close the driver's
door to turn off RAP.
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. 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.

2-83
Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or may
begin programs to inspect the emission control equipment
on your vehicle. Failure to pass this inspection could
prevent you from getting a vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON light is on or not
working properly.
Your vehicle will not pass this inspection if the
OBD (on
-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle would
be considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.
Oil Pressure Light
This light tells you if there
could be a problem with
your vehicle's engine
oil pressure.
The oil pressure light can come on briefly when you
turn your key to RUN. It goes off once you turn the key
to START. That's just a check to be sure the light works.
This is normal and doesn't show a problem. If it doesn't
come on and then go off, be sure to have it fixed so it
will be there to warn you if there is a problem.
When this light comes on and stays on, and a chime
sounds, it means oil isn't going through the engine
properly. The oil could be low, or there might be some
other oil problem. See your dealer for service.

2-84
CAUTION:
Don't keep driving if the oil pressure is low.
If you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Service Vehicle Soon Light
This light will come on if
your vehicle has certain
non
-emission
related problems.
For example, if the entire electrical system fails to send
and receive messages from the vehicle's components,
the SERVICE VEHICLE SOON warning light
comes on.
These problems may not be obvious and may affect
vehicle performance or durability. Consult a qualified
dealership for necessary repairs to maintain top vehicle
performance. This light will come on briefly when the
ignition is turned on to show that it is working properly.

2-86
Driver Information Center (DIC)
(If Equipped)
Your vehicle may be equipped with a Driver Information
Center (DIC). The DIC will display information about
how your vehicle is functioning, as well as warning
messages if a system problem is detected.
The following buttons are
on the DIC control panel
which is located to the left
of the steering column:

ODO/TRIP: Use this button to display your total and
trip miles.

FUEL INFO: Press this button to display fuel
information such as fuel used, fuel range and
fuel economy.
GAGE INFO: Use this button to display oil pressure,
oil life, coolant temperature, tire pressure and
battery information.

RESET: This button, used along with other buttons,
will reset system functions.

ENG/MET: Use this button to change the display
between English and metric units.DIC Controls and Displays
There are two lines in the DIC display. The bottom line on
the display area is left blank when the DIC displays the
driver number identified when entering the vehicle. You
can have your dealer program your name to appear on this
display line. See your dealer for more information.
When you turn the ignition on, the DIC will display your
DRIVER NUMBER. The system will then perform a status
check and display any messages if a problem is detected.
If there are no problems detected, the display will return
to the mode selected by that driver the last time the
ignition was turned off.
