To program the new key:
1. Insert the ignition key in the ignition and start the
engine. If the engine will not start see your dealer
for service.
2. After the engine has started, turn the key to OFF, and
remove the key.
3. Insert the key to be programmed and turn it to RUN
within 10 seconds of removing the previous key.
4. The PASS KEY light will turn off once the key has
been programmed. It may not be apparent that the
PASS KEY light went on due to how quickly the key
is programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the PASS KEY light comes
on and stays on, you will be able to restart your engine if
you turn it off. Your PASS
-Key III system, however, is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by the PASS
-Key
III system at this time.
If you lose or damage a PASS
-Key III key, see your
dealer or a locksmith who can service PASS
-Key III to
have a new key made.
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the long
run if you follow these guidelines:

Don't drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.

3. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try this:
Wait 15 seconds to let the starter motor cool down.
Then push your accelerator pedal all the way to the
floor. Hold it there. Then hold the key in START.
This clears the extra gasoline from the engine. When
the engine starts, let go of the key and the accelerator
pedal. If the engine still doesn't start, wait another
15 seconds and repeat this step.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See ªTowing
Your Vehicleº in the Index.
Engine Coolant Heater (If Equipped)
In very cold weather, 0
F (-18
C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm
-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.

Automatic Transaxle Operation
Maximum engine speed is limited when you're in
PARK (P) or NEUTRAL (N), to protect driveline
components from improper operation.
There are several different positions for your shift lever.
PARK (P): This gear position locks your front wheels.
It's the best position to use when you start your engine
because your vehicle can't move easily.
Ensure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has Brake
-Transaxle
Shift Interlock (BTSI). You must fully apply your
regular brakes before you can shift from PARK (P)
when the ignition key is in RUN. As you step on the
brake pedal, while in PARK (P), you may hear a click
from the solenoid of the BTSI. This ensures that the
BTSI is operating properly.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 this section.
CAUTION:
It is 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 have 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).
See ªShifting Into PARK (P)º in the Index. If
you're pulling a trailer, see ªTowing a Trailerº in
the Index.

AUTOMATIC OVERDRIVE (D): This position is for
normal driving. If you need more power for passing,
and you're:

Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You'll shift down to the next gear and have more power.
NOTICE:
If your vehicle seems to start up rather slowly, or
if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens, have
your vehicle serviced right away. Until then, you
can use SECOND (2) when you are driving less
than 35 mph (55 km/h) and AUTOMATIC
OVERDRIVE (D) for higher speeds.
THIRD (3): This position is also used for normal
driving, but it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE.
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):

When driving on hilly, winding roads.

When towing a trailer (so there is less shifting
between gears).

When going down a steep hill.
SECOND (2): This position gives you more power, but
lower fuel economy. You can use SECOND (2) on hills.
It can help control your speed as you go down steep
mountain roads, but then you would also want to use
your brakes off and on.

Parking Brake
To set the parking brake,
hold the regular brake pedal
down with your right foot
and push down on the
parking brake pedal with
your left foot.
If the ignition is on, the brake system warning light will
come on. See ªBrake System Warning Lightº in
the Index.
To release the parking brake, hold the regular brake
pedal down with your right foot while you push down
on the parking brake pedal with your left foot. (To
release the tension on the parking brake cable, you will
need to apply about the same amount of pressure to the
parking brake pedal as you did when you set the parking
brake.) When you remove your foot from the parking
brake pedal, it will pop up to the released position.NOTICE:
Driving with the parking brake on can cause
your rear brakes to overheat. You may have to
replace them, and you could also damage other
parts of your vehicle.
If you are towing a trailer and are parking on any hill,
see ªTowing a Trailerº in the Index. That section shows
what to do first to keep the trailer from moving.

Shifting Into PARK (P)
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. If
you have 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, use the steps that
follow. If you're pulling a trailer, see ªTowing a
Trailerº in the Index.
1. Hold the brake pedal down with your right foot and
set the parking brake with your left foot.2. Move the shift lever into PARK (P) like this:
Pull the lever toward you.

2-50 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 Brake-Transaxle Shift Interlock
(BTSI). You have to fully apply your regular brakes
before you can shift from PARK (P), when the ignition
is in RUN.
