0 Move the lever up as far as it will go.
3. If you have four-wheel drive, be sure the transfer
case is in a drive gear
-- not in NEUTRAL (N).
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
hand, your vehicle
is in PARK (P).
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.

Parking Your Vehicle (Manual
Transmission Models Only)
Before you get out of your vehicle, put your manual
transmission
in REVERSE (R), turn off the engine, and
firmly apply the parking brake.
If you have four-wheel drive, be sure your transfer case
is in a drive gear. Your vehicle could roll
if it isn’t.
If you are parking
on a hill, or if you are pulling a
trailer, see “Towing a Trailer” in the Index.

A 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 firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is
running unless you have to.
If you’ve 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 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). Always
set your parking brake. Follow the proper steps
to be
sure your vehicle won’t move. See “Shifting Into
PARK
(P)” in the Index.
If you’re pulling a trailer,
see “Towing a Trailer” in
the Index.

Cruise Control (If Equipped)
With cruise control, you can
maintain a speed of about
25 mph (40 km/h) or more
without keeping your foot
on the accelerator. This can
really help on
long trips.
Cruise control does
not
work at speeds below about
25 mph (40 km/h).
When you apply your brakes, the cruise control
shuts
off.
0 Cruise control can be dangerous where you
can't drive safely at a steady speed.
So,
don't use your cruise control on winding
roads or in heavy traffk.
slippery roads. On such roads,
fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.

Setting Cruise Control Resuming a Set Speed
If you leave your cruise control switch on when
you9re not using cruise, you might hit a button
and
go into cruise when you don’t want to. You
could be startled and even lose control. Keep
the cruise control switch
OFF until you want
to use it.
1. Move the cruise switch to ON.
2. Get up to the speed you want.
3. Press in the SET button
at the end
of the lever
and release
it.
4. Take your foot off the
accelerator pedal. Suppose
you set your cruise control at a desired speed
and then you apply the brake. This,
of course, shuts off
the cruise control.
But you don’t need to reset it.
Once you’re going about
25 mph (40 kdh) or more,
you can move the cruise
switch from
ON to
RIA (Resume/Accelerate)
for about half a secQp4,
You’ll
go right back up to your chosen speed and
stay there.
Remember, if you hold the switch at R/A longer than
half a second, the vehicle will keep going faster
until
you release the switch or apply the brake. So unless you
want to
go faster, don’t hold the switch at WA.

Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher speed.
Press the button at the end of the lever, then release
the button and the accelerator pedal. You’ll now
cruise at the higher speed.
Move the cruise switch from ON to R/A. Hold it
there until you get up to the speed you want, and
then release
the switch. (To increase your speed in
very small amounts, move the switch to
R/A for less
than half a second. Each time you do this, your
vehicle will go about
1 mph (I .6 km/h) faster.)
Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:
Press in the button at the end of the lever until you
reach the lower speed you want, then release
it.
To slow down in very small amounts, press the
button for less than half a second. Each time you do
this, you’ll go
1 mph (1.6 km/hl slower.
Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When
you take your foot off
the pedal, your vehicle will slow
down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load
and the steepness of the hills.
When going up steep hills, you may have to step on the
accelerator pedal to maintain your speed.
If the steepness
of the hill causes the vehicle speed to drop more than
15 mph (24 km/h) below the set speed, your cruise control
will automatically disengage. When going downhill, you
may have to brake or
shift to a lower gear to keep your
speed down.
Of course, applying the brake takes you out
of cruise control. Many drivers find this to
be too much
trouble and don’t use cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
0 Step lightly on the brake pedal or
0 Move the cruise switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory
is erased.

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.
the headlamp switch is off and
the parking brake is released.
