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:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in.
If it is, turn the steering wheel left and right while
you turn the key hard. If none of this 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
climate control system.
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 the 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 Procedure
1. With your foot off the accelerator pedal, turn your
ignition 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 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
run your engine at high speed 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. Any resulting damage
would not be covered by your vehicle’s warranty.
2-19

Engine Coolant Heater
Your vehicle has 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 cord is located on the driver’s side of the
engine compartment, behind 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 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 2-27.
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 2-28.
2-21

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 down and 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, see
If Your Vehicle is Stuck in Sand, Mud, Ice or Snow on
page 4-27.
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)
while the engine is running at high speed may
damage the transaxle. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speeds when shifting your vehicle.
2-22

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.

Manual Transaxle Operation
Five-Speed
This is your shift pattern.
Here is how to operate your manual transaxle:
FIRST (1):Press the clutch pedal and shift into
FIRST (1). Then, slowly let up on the clutch pedal as
you press the accelerator pedal.
You can shift into FIRST (1) when you are going less
than 20 mph (32 km/h). If you have come to a complete
stop and it is hard to shift into FIRST (1), put the shift
lever in NEUTRAL and let up on the clutch. Press
the clutch pedal back down. Then shift into FIRST (1).SECOND (2):Press the clutch pedal as you let up on
the accelerator pedal and shift into SECOND (2).
Then, slowly let up on the clutch pedal as you press the
accelerator pedal.
THIRD (3), FOURTH (4) and FIFTH (5):Shift into
THIRD (3), FOURTH (4) and FIFTH (5), the same way
you do for SECOND (2). Slowly let up on the clutch
pedal as you press the accelerator pedal.
To stop, let up on the accelerator pedal and press the
brake pedal. Just before the vehicle stops, press
the clutch pedal and the brake pedal, and shift to
NEUTRAL.
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.
2-25

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 PARK (P) by pushing the
lever toward the passenger side of the vehicle and
then up.
3. Turn the ignition 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 (Automatic Transaxle)
{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).
