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.
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 “Shifting
Into Park
(P)” in the Index. If you’re pulling a
trailer, see “Towing a Trailer”
in the Index.
REVERSE
(R): Use this gear to back up.
Notice: Shifting to REVERSE (R) while your vehicle
is moving forward could damage your transmission.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow, ice
or sand without damaging your transmission, see
If You
Are Stuck: In Sand, Mud, Ice or Snow on page 4-42.
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
NEUTRF’
lk’’ when your vehicle is beir- towed.
Shifting into a drive gear while your engine
is
“racing” (running at high speed) is dangerous.
Unless your foot
is firmly 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 transmission caused by
shifting out of PARK
(P) or NEUTRAL (N) with
the engine racing isn’t covered by your warranty.
DRIVE (D): This position is for normal driving. If
you need more power for passing, and you’re:
0 Going less than about 35 mph (55 km/h), push your
Going about 35 mph (55 km/h) or more, push the
accelerator
pedal about halfway down.
accelerator all the way down.
You’ll shift down to the next gear and have more power.

Parking Brake
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.
A chime will activate and the warning light will flash
when the parking brake is applied and the vehicle
is moving at least
3 mph (5 km/h) for at least three
seconds.
If the ignition is on when the parking brake is released,
the brake system warning light will go
off.
Notice: Driving with the parking brake on can
cause your rear brakes
to overheat. You may have
to replace them, and you could also damage
other parts
of your vehicle.
If you are towing a trailer and are parking on any hill,
see
Towing a Trailer on page 4-51.
To release the parking brake, hold the regular brake
pedal down. Pull the bottom edge
of the lever, located
above the parking brake pedal, with the parking
brake symbol, to release the parking brake.
2-22

Shifting Into Park (P)
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. 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,
use the steps that follow.
With four-wheel
drive, if your transfer case
is in NEUTRAL,
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. If you’re pulling a trailer, see
“Towing a Trailer’’
in the Index.
1. Hold the brake pedal down with your right foot and
2. Move the shift lever into PARK (P) like this:
set
the parking brake.
/ 1
I.
Pull the shift lever toward you.
2-23

Move the lever up as far as it will go.
3. Turn the ignition key to LOCK.
4. 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
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.
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.
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).
2-24

Torque Lock
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 lnto
Park
(P) on page 2-23.
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)
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
is in RUN. See Automatic Transmission
Operation on page
2- 18.
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 into the 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 LOCK.
2. Apply and hold the brake until the end of Step 4.
3. Shift the vehicle to NEUTRAL (N).
4. Start the vehicle and then shift to the drive gear
5. Have the system fixed as soon as you can.
you want.

Running Your Engine While You
Are Parked
It’s better not to park with the engine running. But if you
ever have
to, here are some things to know.
Idling the engine with the climate control
system
off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
“Engine Exhaust.’’
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan is at the highest setting. One place
this
can happen is a garage. Exhaust - with
CO
- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be
a blizzard. See
“Winter Driving’’ in the Index.
It can be d,,,gersus to b-. dt 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).
Follow the proper steps to be sure your vehicle won’t
move. See
Shifting Into Park (P) on page 2-23.
If you’re pulling a trailer, see Towing a Trailer on
page 4-5 1.

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. Fully functional
daytime running lamps are required on all vehicles
first sold in Canada.
The DRL system will come on when the following
conditions are met:
The ignition is on,
0 the exterior lamp control is in AUTO
0 the automatic transmission is not in PARK (P), and
0 the light sensor determines it is daytime.
When the
DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either. When
it begins to
get dark, the automatic headlamp
system will switch from DRL to the headlamps or the last
chosen headlamp setting that was used.
W-hen you turn the exterior iamp controi
to off, the
headlamps will go off, and your DRL lamps will
illuminate, provided it is not dark outside.
Shifting the transmission into PARK
(P) will allow you to
idle the vehicle with the DRL off. The DRL will stay
off until you release the parking brake or shift the
transmission out of PARK (P).
Puddle Lamps
Your vehicle is equipped with puddle lamps to help you
see the area near the base
of the front doors when it
is dark out. The puddle lamps will illuminate when a door
is opened or when you press the UNLOCK button on
the keyless entry transmitter.
