Your vehicle may have
this feature.
A sliding
door security lock helps
to prevent young children
or other passengers
from opening the sliding
door using the inside
door handle.
The security door lock is located near the front of the
sliding door. There are two labels on
your vehicle to remind you that
you have this feature. One can be seen from the outside
on your sliding door.
It is located near the bottom of the
door glass, toward the front
of the door. The other label is
located on the front
of the sliding door, near the security
door lock.
This feature prevents passengers from opening the sliding side door from the inside.
To use this feature, do the following:
1. Move the lever all the way up.
2. Close the door.
To open the sliding side door while the security lock is
engaged, unlock the door and open it from the outside.
If you don’t cancel the security lock feature, adults or
older children who ride in the rear won’t be able to open
the sliding door from the inside. You should let adults
and older children know how the security door lock
works, and how to cancel the lock.

Power Windows
If you have power windows, the controls are located on
each of the front doors. The driver’s door also has a
switch for the front passenger window. Your power
windows will not work unless the ignition is in RUN or
ACCESSORY, or unless retained accessory power
is active. See “Retained Accessory Power” under
Ignition Positions on page 2-19.
Express-Down Window
The driver’s window switch also has an express-down
feature that allows you to lower the window without holding the switch. Press the down arrow on the driver’s
window switch marked AUTO briefly to activate the
express-down feature. The express-down feature can
be interrupted at any time by pressing the up arrow
end of the switch. Lightly tap the switch to open

Theft-Deterrent Systems
Vehicle theft is a big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make
it impossible to steal. However, there are ways you
can help.
Passlock@
Your vehicle is equipped with the Passlock@
theft-deterrent system.
Passlock@ is a passive theft-deterrent system. Passlock@
enables fuel
if the ignition lock cylinder is turned with
a valid key.
If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled. During normal operation,
the SECURITY light will
go off
approximately five seconds after the key is turned
to RUN.
If the engine stalls and the SECURITY light flashes, wait
until the light stops flashing before trying to restart the
engine. Remember to release the key from START as
soon as the engine starts.
If the engine is running and the SECURITY light comes
on, you will be able to restart the engine
if you turn
the engine
off. However, your Passlock@ system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock@ at this
time. You may also want to check the fuse.
See
Fuses and Circuit Breakers on page 5-93.
See your dealer for service.

Starting and Operating
Your Vehicle
New Vehicle Break-in
Nofice: Your vehicle doesn’t need an elaborate
“break-in.” But
it will perform better in the long run
if you follow these guidelines:
e
e
Keep your speed at 55 mph (88 km/h) or less
for
the first 500 miles (805 km).
Don’t drive at any one speed
- fast or
slow
- for the first 500 miles (805 km).
Don’t make full-throttle starts.
Avoid making hard stops for the first
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 “Towing
a Trailer” in the Index for more information.
Ignition Positions
With the key in the ignition, you can turn it to five
different positions.
C
A
A (ACCESSORY): This position lets you use things like
the radio, power windows and windshield wipers when
the engine is off.
To get into ACCESSORY, push in the
key and turn it toward you. Your steering wheel will
remain locked, just as it was before you inserted the key.
2-1 9

Notice: Don’t operate accessories in the
ACCESSORY position for long periods of time.
Prolonged operation of accessories in the
ACCESSORY position could drain your battery
and prevent you from starting your vehicle.
B (LOCK): This position locks your ignition, steering
wheel and transmission. It’s a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.
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 this works, then your vehicle needs service.
C (OFF): This position lets you turn off the engine but
still turn the steering wheel. Use
OFF if you must
have your vehicle in motion while the engine is
off
(for example, if your vehicle is being towed).
D (RUN): This is the position for driving.
E (START): This position starts your engine.
Retained Accessory Power (RAP)
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow certain features
on your vehicle to continue to work up to
20 minutes
after the ignition key is turned
to OFF.
Your radio, power windows and overhead console will
work when the ignition key is in RUN or ACCESSORY
Once the key is turned from RUN to
OFF, these
features will continue to work for up to
20 minutes or
until a door is opened.

Automatic Transmission Operation
There are several different positions for your shift lever.
PARK (P): This position locks your rear wheels.
It’s the best position to use when you start your
engine because your vehicle can’t move easily.
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.
CAUTION: (Continued) Don’t leave your vehicle when
the enL le
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 “Shifting Into Park (P)” in the
Index. If you’re pulling
a trailer, see “Towing a
Trailer” in the Index.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transmission
shift lock control system. You have to fully apply your
regular brakes before you can shift from PARK (P) when
the ignition key is in
RUN. If you cannot shift out of
PARK (P), ease pressure on the shift lever
- push the
shift lever all the way into PARK (P) as you maintain
brake application. Then move the shift lever into
the gear you wish. See
Shifting Out of Park (P) on
page
2-29.
