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
a maximum of 15 seconds. This clears the extra
gasoline from the engine. If the engine still won't start
or starts briefly but then stops again, repeat step 1 or 2,
depending on temperature. When the engine starts,
release the key and the accelerator pedal.
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.
Starting Your 3400 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. If it doesn't start in three seconds (or starts
but then stops), push the accelerator pedal about
one
-quarter of the way down for 12 more seconds, or
until it starts.

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.

Engine Coolant Heater (If Equipped)
2.4L L4 Engine

yellowblue
2-19
3400 V6 Engine
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. On
the 2.4L L4 engine the engine coolant heater cord is
located in front of the engine coolant surge tank. On
the 3400 V6 engine the engine coolant heater cord is
located near the air cleaner/filter.
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 console between
the seats.
PARK (P): This 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
2-21
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 apply your regular
brake before you can shift from PARK (P) when the
ignition key is in ON. 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) and 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.) See ªShifting Out of
PARK (P)º later in this section.
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 (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, however, it offers more power and lower fuel
economy than AUTOMATIC OVERDRIVE (D). 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.
NOTICE:
Don't drive in SECOND (2) for more than
25 miles (41 km), or at speeds over 55 mph
(88 km/h), or you can damage your transaxle. Use
AUTOMATIC OVERDRIVE (D) 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.

yellowblue
2-23
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 can 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.
Parking Brake
To set the parking brake, hold the regular brake pedal
down with your right foot. Pull up on the parking brake
handle. If the ignition is on, the brake system warning
light will come on.

yellowblue
2-24
To release the parking brake, hold the regular brake
pedal down. Pull the parking brake handle up until you
can press the release button. Hold the release button in
as you move the brake handle all the way down.
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 a 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.
