2-21 Retained Accessory Power (If Equipped)
If you have this option, after you turn the ignition off
and even remove the key, you will still have electrical
power to such accessories as the radio and power
windows for up to 10 minutes. Power is turned off if you
open a door.
Always leave your key in LOCK. If you leave your key
in any other position than LOCK, your battery will
discharge prematurely.
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.

yellowblue
2-23 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
electrical cord is located on the passenger's side of
the engine compartment near the battery.
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 may have a shift lever located
on the console between the seats or on the
steering column.
There are several different positions for your shift lever.
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.

yellowblue
2-25
Ensure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has a Brake
-Transaxle
Shift Interlock (BTSI). You have to fully apply your
regular brakes before you can shift from PARK (P)
when the ignition key is in an on position. If you cannot
shift out of PARK (P), ease pressure on the shift
lever
-- push the shift lever all the way into PARK (P)
and also release the shift lever button on floor shift
console models as you maintain brake application. Then
move the shift lever into the gear you wish. (Press the
shift lever button before moving the shift lever on floor
shift console models.) 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.
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 (
) for higher speeds.
DRIVE (D): 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 DRIVE (D)
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 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.
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
DRIVE (D) 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.

yellowblue
2-27
FIRST (1): This position gives you even more power
(but lower fuel economy) than SECOND (2). You can
use it on very steep hills, or in deep snow or mud. If the
selector lever is put in FIRST (1), the transaxle won't
shift into first gear until the vehicle is going
slowly enough.
NOTICE:
If your front wheels can't rotate, don't try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transaxle.
Also, if you stop when going uphill, don't hold
your vehicle there with only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into PARK (P)
to hold your vehicle in position on a hill.
Performance Shifting (Option)
Press PERFORM SHIFT to
allow the transaxle to shift
at higher engine speeds,
increasing acceleration
performance. An indicator
light on the switch will
glow when performance
shifting is in operation.
Downshifts will occur at a lower percentage of
accelerator application while you're in the
PERFORM SHIFT mode.
Press NORMAL SHIFT to have the transaxle shift at
lower engine speeds, increasing fuel economy. An
indicator light on the switch will glow when normal
shifting is in operation.

Computer Command Ride (Option)
Vehicles equipped with computer command ride provide
improved passenger ride comfort under a variety of road
and driving conditions.
For normal driving conditions, press the
TOURING RIDE button to get a more refined
comfortable ride. When driving conditions require
improved handling, press the PERFORM RIDE button
to get a firm ride. This mode minimizes how much the
passenger compartment leans in turns, and decreases the
up
-and-down motion of the front and rear of the vehicle
during acceleration or braking.
Even in the TOURING RIDE mode, the system will
adjust to rapid cornering, acceleration or braking.
If the computer command ride detects a problem in the
system, the lights on the TOURING RIDE and
PERFORM RIDE buttons will both come on. If this
happens, have your vehicle serviced.
Parking Brake
Your vehicle has a PUSH
TO RELEASE parking
brake. To set the parking
brake, hold the regular
brake pedal down with your
right foot. Push down the
parking brake pedal with
your left foot. If the ignition
is on, the brake system
warning light will come on
and a single chime will
be heard.
If you start to drive with the parking brake set, a chime
will sound after the vehicle has traveled approximately
40 feet (12 m).
