To unlock the driver’s door, press the UNLOCK
button.
If you press this button again within five seconds, all the
remaining doors (except the third door)
will unlock. The

Matching Transmitter(s) To Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any remaining transmitters with you when you
go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have
only four transmitters
matched to it. Under normal use,
the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If
you have to
get close to your vehicle before the transmitter works,
it’s probably time to change the battery.
NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage
the transmitter.
Use one three volt, type CR2032, or equivalent battery.

Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for
joy riders or professional thieves -- so
don’t do it.
When you park your vehicle and open the driver’s door, you’ll hear a tone reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and
so will your
ignition.
If you have an automatic transmission, taking
your key out also locks your transmission. And
remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember
to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it’s best to lock it
up and take your keys.
But what
if you have to leave your ignition key? What if
you have to leave something valuable in your vehicle?
Put your valuables in a storage area, like your
glove box.
Lock all the doors except the driver’s.
New Vehicle “Break-In”
NOTICE:
Your modern vehicle doesn’t need an elaborate
“break-in.” But it will perform better in the long
run
if you follow these guidelines:
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.
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.
0 Don’t tow a trailer during break-in. See
“Towing a Trailer’’ in the Index for
more information.

Ignition Positions
You can use your key to turn your ignition switch to five
different positions.
A E
ACCESSORY (A): ACCESSORY lets you use things
like the radio, power windows and the windshield
wipers when the engine
is off. Push in the key and turn
it towards you. Your steering wheel will remain locked,
just as it was before you inserted the key.
LOCK (B): 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.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn’t lock the steering
wheel like
LOCK. Use OFF if you must have your
vehicle
in motion while the engine is off (for example,
your vehicle
is being pushed).
RUN (D): This is the position for driving.
START (E): This starts your engine.

If your vehcle is equipped with an automatic transmission,
it now features an electronic shift position indicator within
the instrument cluster. This display must be powered
anytime the
shift lever is capable of being moved out of
PARK (P). This means that if your key is in OFF, rather
than
LOCK, there will be a small current drain on your
battery which could discharge your battery over
a period
of time. If you have to leave your key in the
ignition
in OFF for an extended period, it is recommended
that you disconnect the battery cable from the battery to
prevent discharging your battery.
PARK
(P): This 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)
I
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).
If you have four-wheel drive, your vehicle
will be free to roll -- even if your shift lever
is in PARK
(P) -- if your transfer case is in
NEUTRAL
(N). So, be sure the transfer case is in
a drive gear, two-wheel high
(2H) or four-wheel
high
(4H) or four-wheel low (4L) -- not in
NEUTRAL
(N). See “Shifting Into PARK (P)” in
the Index.

4. Turn the ignition key to LOCK.
5. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your

Leaving Your Vehicle With the Engine
Running (Automatic Transmission
Models Only)
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 firmly set.
If you have
four-wheel drive with
a manual transfer case
shift lever and your transfer case is in
NEUTRAL
(N), your vehicle will be free to roll,
even if your shift lever is in PARK
(P). So be sure
the transfer case is in
a drive gear -- not in
NEUTRAL
(N). And, if you leave the vehicle with
the engine running, it could overheat and even
catch fire.
You or others could be injured. Don’t
leave your vehicle with the engine running unless
you have
to.

If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and the
parking brake is firmly set before you leave
it. After you
move 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) without first pulling it
toward
you. If you can, it means that the shift lever
wasn’t fully locked into PARK
(P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you don’t shift your
transmission into PARK (P) properly, the weight of the
vehicle may put
too much force on the parking pawl in
the transmission. You may find
it difficult to pull the
shift lever out of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and then
shift into PARK (P) properly before you leave the
driver’s seat.
To find out how, see “Shifting Into
PARK (P)” in the Index.
When you are ready
to drive, move the shift lever out of
PARK (P)
before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill
to take some of the
pressure from the parking pawl in the transmission,
so
you can pull the shift lever out of PARK (P).
Shifting Out of PARK (P)
(Automatic Transmission)
Your vehicle has a brake-transmission shift interlock
system. You have
to fully apply your regular brakes
before you can shift from PARK (P) when the ignition
is in RUN. See “Automatic Transmission” in the Index.
If you cannot shift out of PARK (P), ease pressure on
the shift lever and push the shift lever all the way up
into PARK (P) as you maintain brake application. Then,
move the shift lever to any gear you want.
If you ever hold the brake pedal down but still can’t
shift out
of PARK (P), try this:
1. Turn the key to OFF,
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the vehicle and shift to the drive gear you want.
5. Have the brake-transmission shift interlock system
fixed as soon as you can.

Headlamps On Reminder
A buzzer will sound when your headlamps are turned
on and the key is turned to the
OFF, LOCK or
ACCESSORY position. If
you need to use your
headlamps when the key is turned to
OFF, LOCK or
ACCESSORY, the buzzer can be turned
off by turning
the thumb wheel next to the parking lampheadlamp
knob all the way down.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front
of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful
in the
short periods after dawn and before sunset.
The DRL system will make your headlamps come
on at
a reduced brightness when:
the ignition is on,
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be on.
Your instrument panel won’t be
lit up either.
When it begins to get dark, your DRL indicator light
is a
reminder to turn your headlamp switch on. The other
lamps that come on with your headlamps will also
come
on.
When you turn off the headlamp switch, the regular
lamps will go off, and your headlamps will change to
the reduced brightness
of DRL.
To idle your vehicle with the DRL off, set the parking
brake. The DRL will stay off until you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
