Ignition Positions
With the key in the ignition
switch, you can turn the
key to four different
positions.
{CAUTION:
On manual transaxle vehicles, turning the key
to LOCK and removing it will lock the steering
column and result in a loss of ability to steer
the vehicle. This could cause a collision. If you
need to turn the engine off while the vehicle is
moving, turn the key only to ACC. Do not push
the key in while the vehicle is moving.Notice:If your key seems stuck in LOCK and you
can not 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. Turn
the key only with your hand. Using a tool to force it
could break the key or the ignition switch. If none of
these works, then your vehicle needs service.
LOCK:This position locks your steering wheel, ignition,
shift lever and transaxle. This is the only position in
which you can insert or remove the key. For easier key
operation when unlocking the steering wheel, move the
steering wheel from right to left and turn the key to ACC.
ACC (ACCESSORY):This position operates some of
your electrical accessories, such as the radio, but
not the ventilation fan.
ON:This is the position to which the switch returns after
you start your engine and release the key. The switch
stays in ON when the engine is running. But even when
the engine is not running, you can use ON to operate
your electrical accessories, and to display some
instrument panel warning lights.
START:This position starts the engine. When the
engine starts, release the key. The switch will return to
ON for normal driving. Do not turn the key to START
if the engine is running.
Even if the engine is not running, ACC and ON allow
you to operate electrical accessories, such as the radio.

Starting Your Engine
Automatic Transaxle
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Shifting into PARK (P) with the vehicle
moving could damage the transaxle. Shift into
PARK (P) only when your vehicle is stopped.
Manual Transaxle
The shift lever should be in NEUTRAL and the parking
brake engaged. Hold the clutch pedal to the floor and
start the engine. Your vehicle will not start if the clutch
pedal is not all the way down — that is a safety feature.
Starting Your Engine
1. With your foot off 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 does not start, wait about 15 seconds and try
again to start the engine by turning the ignition key to
START. Wait about 15 seconds between each try.
When your engine has run about 10 seconds to
warm up, your vehicle is ready to be driven. Do not
race your engine when it is cold.
If the weather is below freezing (32°F or 0°C),
let the engine run for a few minutes to warm up.
3. If your engine still will not 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.
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 do not, your engine
might not perform properly.

Engine Coolant Heater (Canada Only)
Your vehicle may have an engine coolant heater. In
very cold weather 0°F (−18°C) or colder, the engine
coolant heater can help. You will 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. At
temperatures above 32°F (0°C), use of the coolant
heater is not required.
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 near the battery.
3. Plug the cord 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
CAUTION: (Continued)
CAUTION: (Continued)
and cause a re. You could be seriously injured.
Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not 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 do not, 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 will be
parking your vehicle. The dealer can give you the
best advice for that particular area.

Automatic Transaxle Operation
If your vehicle has an automatic transaxle, the shift
lever is located on the console between the seats.
Movement between certain positions requires pushing
the shift lever toward the passenger side while shifting.
This prevents you from changing positions unexpectedly
by blocking the straight movement of the shift lever
while the vehicle is moving.PARK (P):This position locks your front wheels. It is
the best position to use when you start your engine
because your vehicle cannot 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 rmly set. Your vehicle can roll.
Do not 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 will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P).
SeeShifting Into Park (P) (Automatic Transaxle)
on page 2-29.
2-22

Ensure that 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 apply
your regular brakes before you can shift from PARK (P)
when the key is in ON. If you cannot shift out of
PARK (P) while holding the brake pedal down, see
Shifting Out of Park (P) (Automatic Transaxle) on
page 2-30.
REVERSE (R):Use this gear to back up.
When shifting from NEUTRAL (N) to REVERSE (R),
you need to apply the regular brake and push the shift
lever toward the passenger side of the vehicle and
then forward.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transaxle.
The repairs would not be covered by your warranty.
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,
seeIf You Are Stuck: In Sand, Mud, Ice or Snow
on page 4-28.NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart while you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine racing may damage the transaxle.
The repairs would not be covered by your warranty.
Be sure the engine is not racing when shifting
your vehicle.
2-23

AUTOMATIC OVERDRIVE (D4):This position is for
normal driving.
Notice:Driving your vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transaxle. Have your vehicle
serviced right away. You can drive in SECOND (2)
when you are driving less than 35 mph (55 km/h) and
AUTOMATIC OVERDRIVE (D4) for higher speeds
until then.
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:Do not drive in SECOND (2) at speeds
over 65 mph (105 km/h), or you can damage
the transaxle. Use AUTOMATIC OVERDRIVE (D4) as
much as possible. Do not shift into SECOND (2)
unless you are going slower than 65 mph (105 km/h)
or you can damage your engine.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
shift lever is put in FIRST (1), the transaxle will not shift
into first gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
If there is a malfunction with the automatic transaxle,
the malfunction indicator lamp (MIL) or the HOLD
indicator light will turn on or flash. SeeMalfunction
Indicator Lamp on page 3-28orHold Mode Light
on page 3-28.
Have your vehicle fixed as soon as possible.
2-24

NEUTRAL:Use this position when you start or idle
your engine.
REVERSE (R):To back up, press down the clutch
pedal, lift up the ring on the shift lever and shift
into REVERSE (R). Let up on the clutch pedal slowly
while pressing the accelerator pedal.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transaxle.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
Also, use REVERSE (R), along with the parking brake,
for parking your vehicle.Shift Speeds
{CAUTION:
If you skip a gear when you downshift, you could
lose control of your vehicle. You could injure
yourself or others. Don’t shift down more than
one gear at a time when you downshift.
2-27

Shifting Into Park (P)
(Automatic Transaxle)
{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 rmly 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 will
not move, even when you are on fairly level
ground, use the steps that follow.
1. Hold the brake pedal down and set the parking
brake.
2. Move the shift lever into the PARK (P) position by
pushing the lever toward the passenger side of the
vehicle and then up.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
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 rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
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
have 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). If you can, it means
that the shift lever was not fully locked into PARK (P).
