Safety Warnings and Symbols
You will ®nd a number of safety cautions in this book.
We use a box and the word CAUTION to tell you about
things that could hurt you if you were to ignore the
warning.
{CAUTION:
These mean there is something that could hurt
you or other people.
In the caution area, we tell you what the hazard is.
Then we tell you what to do to help avoid or reduce the
hazard. Please read these cautions. If you don't, you
or others could be hurt.You will also ®nd a circle
with a slash through it in
this book. This safety
symbol means ªDon't,º
ªDon't do thisº or ªDon't let
this happen.º
iii

Vehicle Damage Warnings
Also, in this book you will ®nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see CAUTION
and NOTICE warnings in different colors or in different
words.
You'll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a speci®c component, control,
message, gage or indicator.
If you need help ®guring out a speci®c name of a
component, gage or indicator, reference the
following topics:
·Seats and Restraint Systems in Section 1
·Features and Controls in Section 2
·Instrument Panel Overview in Section 3
·Climate Controls in Section 3
·Warning Lights, Gages and Indicators in Section 3
·Audio System(s) in Section 3
·Engine Compartment Overview in Section 5

Ignition Positions
With the key in the ignition switch, you can turn it to ®ve
different positions.
(A) ACCESSORY:This position lets you use your
electrical accessories such as power windows, power
sunroof (if equipped), radio and the windshield wipers.
To use, push in the ignition key and turn it toward
you. Your steering wheel will remain locked, just as it
was before you inserted the key.
(B) LOCK:This is the only position in which you can
remove the key. This position locks your ignition,
steering wheel and transaxle. It's a theft-deterrent
feature.
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.
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.
(C) OFF:This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the
steering wheel like LOCK and it doesn't send any
electrical power to the accessories. The instrument
panel cluster will remain powered in LOCK to illuminate
the gear shift indicator. The cluster will also activate
the parking brake light when the parking brake is
set. Use OFF if you must have your vehicle in motion
while the engine is not running.
(D) RUN:This is the position the switch returns to after
you start your engine and release the switch. This is
also the position for normal driving. Even when the
engine is not running, you can use RUN to operate your
electrical accessories and to display some instrument
panel warning lights.
(E) START:This position starts your engine. When the
engine starts, release the key. The ignition switch
will return to RUN for normal driving.
2-22

Key Reminder Warning
If you leave your key in OFF, you will hear a warning
chime when you open the driver's door.
Always leave your key in LOCK while the engine is off.
If you leave it in any other position, you will drain
your battery power.
Retained Accessory Power (RAP)
After you turn the ignition off and remove the key, you
will still have power to such accessories as the
power windows, audio steering wheel controls (if
equipped), clock, sunroof (if equipped) and the radio for
up to 10 minutes. The instrument panel 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.
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 doesn't start within 10 seconds, hold your key in
START for about 10 seconds at a time until your
engine starts. Wait about 15 seconds between
each try.
3. If your engine still won't start (or starts but then
stops), it could be ¯ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
¯oor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
brie¯y but then stops again, do the same thing.
This time keep the pedal down for ®ve or six
seconds to clear the extra gasoline from the engine.
After waiting about 15 seconds, repeat the normal
starting procedure.
2-23

SECOND (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 (
X) 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.
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 won't shift
into ®rst gear until the vehicle is going slowly enough.
Notice:If your front wheels won't turn, 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 to hold your vehicle in position on a hill.
Parking Brake
This vehicle has a PUSH
TO RELEASE parking
brake pedal. 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 in RUN or OFF, the brake system
warning light will turn on while the parking brake is set.
The parking brake uses the brakes on the rear
wheels.
To release the parking brake, hold the regular brake
pedal down and push the parking brake pedal with your
left foot. 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.
