RUN (D): This is the position the switch returns to after
you start your engine and release the switch. This is the
position for normal driving. Even when the engine is not
running, you can use RUN to operate your electrical
power accessories and to display some instrument panel
warning lights.
START (E): This position starts your engine. When the
engine starts, release the key. The ignition switch will
return to RUN for normal driving.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
Key Reminder Warning
If you leave your key in the OFF ignition position, you will
hear a warning chime when you open the driver's door.
Always leave your key in LOCK. If you leave it in any
other position, you will drain your battery power.
Retained Accessory Power
After you turn the ignition off and remove the key, you
will still have electrical power to such accessories as the
power windows, audio steering wheel controls, clock,
sunroof (if equipped) and the radio for up to 10 minutes.
The instrument cluster lights will stay on for a few
seconds, then will go out. Once you open a door, the
power will shut off.

Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position
-- that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only.
NOTICE:
Don't try to shift to PARK (P) if your vehicle is
moving. If you do, you could damage the
transaxle. Shift to PARK (P) only when your
vehicle is stopped.
Starting Your V6 Engine
1. Without pushing the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid
draining your battery or damaging your starter.

2. If it doesn't start right away, hold your key in
START for about three to five seconds at a time until
your engine starts. Wait about 15 seconds between
each try to help avoid draining your battery or
damaging your starter.
3. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline. Try
pushing your accelerator pedal all the way to the floor
and holding it there as you hold the key in START for
about three seconds. If the vehicle starts briefly but
then stops again, do the same thing, but this time keep
the pedal down for five or six seconds. This clears the
extra gasoline from the engine. After waiting about
15 seconds, repeat the normal starting procedure.
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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The engine coolant heater cord is located on
the passenger's side of the vehicle, above the
headlamp assembly.
3. Plug it into a normal, grounded 110
-volt AC outlet.
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three
-prong
11 0
-volt AC outlet. If the cord won't reach, use a
heavy
-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug and store
the cord as it was before to keep it away from moving
engine parts. If you don't, it could be damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Automatic Transaxle Operation
Your automatic transaxle has a shift lever located on the
steering column.
PARK (P): This position locks your front wheels.
It's the best position to use when you start your engine
because your vehicle can't move easily.
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.

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 is in RUN. If you cannot
shift out of PARK (P), ease pressure on the shift lever
and 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.

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

Going less than about 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.
THIRD (3): This position is also used for normal
driving, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (
).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (
):

When driving on hilly, winding roads

When towing a trailer, so there is less shifting
between gears

When going down a steep hillSECOND (2): This position gives you more power
but lower fuel economy than THIRD (3). 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.
NOTICE:
Don't drive in SECOND (2) for more than
5 miles (8 km), or at speeds over 55 mph
(90 km/h), or you can damage your transaxle.
Use AUTOMATIC OVERDRIVE (
) or
THIRD (3) as much as possible.
Don't shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h), or you can
damage your engine.

To release the parking brake, hold the regular brake
pedal down and push the parking brake pedal with your
left foot. This will release the parking brake pedal.
When you lift your left foot, the parking brake pedal
will follow it to the released position.
If you try to drive approximately 20 feet (6.1 m) with
the parking brake on, the brake light stays on and a
chime sounds until you release the parking brake.
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
explains 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.
