5. While holding the door lock switch in the lock
position, move the shift lever out of and back
into PARK (P).
6. Release the door lock switch to set
the desired mode.
After initially moving the shift lever out of and back into
PARK (P), each additional shift cycle will advance
the programming from the current mode to the next
operating mode. The automatic door lock and unlock
functions will operate as de®ned by each mode
listed previously. If cycled beyond Mode 4, the vehicle
will enter operating Mode 1.
Disconnecting the vehicle's battery for up to a year will
not change the last programmed mode of the
programmable automatic power door locks.Lockout Protection
This feature helps to prevent a driver from locking the
keys inside of the vehicle by disabling the power
door locks when the following occurs:
·A door is opened,
·the key is left in the ignition, and
·a power door lock is pressed.
You may override the lockout protection feature by
holding the power door lock switch in the lock position
for more than three seconds while the key is in the
ignition and any door is open.
Remember, this feature can't guarantee that you'll never
be locked out of your vehicle. If you use the manual
door lock or if you leave the key in your vehicle, but not
in the ignition you could still be locked out of your
vehicle. Always remember to take your keys with you.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out and
close the door. See ªDelayed Lockingº in this section for
more information.

or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
·Make sure all other windows are shut.
·Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See ªClimate Control

Clean and dry the key. Wait about three minutes and try
again. If the starter still won't work, and the key
appears to be clean and dry, wait about three minutes
and try another ignition key. At this time, you may
also want to check the fuse. See
Fuses and Circuit
Breakers on page 5-89. If the starter won't work with the
other key, your vehicle needs service. If your vehicle
does start, the ®rst ignition key may be faulty. See your
dealer or a locksmith who can service the PASS-Key
žII.
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won't work. The
SECURITY warning light on the instrument panel will
then come on. But you don't have to wait three minutes
before trying another ignition key.
See your dealer or a locksmith who can service the
PASS-Key
žII to have a new key made.If you're ever driving and the SECURITY warning light
comes on, you will be able to restart your engine if
you turn it off. Your PASS-Key
žII system, however, is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by the
PASS-Key
žII system.
If you lose or damage a PASS-Key
žII ignition key, see
your dealer or a locksmith who can service

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle doesn't need an elaborate
ªbreak-in.º But it will perform better in the long run
if you follow these guidelines:
·Don't drive at any one speed Ð fast or
slow Ð for the ®rst 500 miles (805 km). Don't
make full-throttle starts.
·Avoid making hard stops for the ®rst 200 miles
(322 km) or so. During this time your new
brake linings aren't yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
·Don't tow a trailer during break-in. See ªTowing
a Trailerº in the Index for more information.
Ignition Positions
With the ignition key in the ignition, you can turn the key
to ®ve different positions:
A (ACCESSORY):This position lets you use the radio
and windshield wipers when the engine is off. To
use ACCESSORY, push in the key and turn it toward
you. Your steering wheel will stay locked.
B (LOCK):This is the only position in which you can
insert or remove the key. This position locks the ignition,
steering wheel and transaxle. It's a theft-deterrent
feature.
2-19

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. Use OFF if you must have your vehicle pushed or
towed.
D (RUN):This position is where the key returns to after
you start your vehicle. With the engine off, you can
use RUN to display some of your warning and
indicator lights.
E (START):This position starts your engine.
A warning chime will sound if you open the driver's door
when the ignition is in OFF, LOCK or ACCESSORY
and the key is in the ignition.Retained Accessory Power (RAP)
With Retained Accessory Power (RAP), your power
windows and audio system will continue to work for up
to 10 minutes after the ignition key is turned to OFF
and before any of the doors are opened.
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.

Automatic Transaxle Operation
The shift lever for the automatic transmission is on the
steering column.
The graphic shown above is displayed on your
instrument panel cluster and will indicate the gear your
vehicle is in.
Maximum engine speed is limited on automatic transaxle
vehicles when you're in PARK (P) or NEUTRAL (N) to
protect driveline components from improper operation.
There are several different positions for your shift lever.{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.
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.
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.
2-23

Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transaxle shift lock control system. You must fully apply
your regular brakes before you can shift from PARK (P)
when the ignition is in RUN. If you cannot shift out
of PARK (P), increase pressure on the shift lever by
pushing is all the way in to PARK (P) while keeping the
brake pedal pushed down. Then move the shift lever
out of PARK (P). See
Shifting Out of Park (P) on
page 2-29
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.
REVERSE (R):Use this gear to back up.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transaxle, see If
You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-31.
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 into a drive gear while your engine is
ªracingº (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.
Don't shift into a drive gear while your engine
is racing.
Notice:Damage to your transaxle caused by
shifting into a drive gear with the engine racing isn't
covered by your warranty.
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
(
X)for higher speeds.
