Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake, or slow, the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not 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.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-27for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.

Ignition Positions
With the ignition key in the
ignition, the key can be
turned to four different
positions.
In order to shift out of PARK (P), the ignition must be in
ON/RUN and the regular brake pedal must be applied.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way.
If none of this works, then your vehicle needs
service.A (LOCK/OFF):This is the only position in which the
ignition key can be inserted or removed. This position
locks the ignition and transmission. It is a theft-deterrent
feature.
If the steering wheel is locked, move it from right to left
and turn the key to ACC/ACCESSORY. If none of
this works, then your vehicle needs service.
B (ACC/ACCESSORY):This position lets the radio
and windshield wipers operate while the engine is off.
To use ACC/ACCESSORY, turn the key clockwise.
C (ON/RUN):This position is where the key returns to
after the vehicle is started. This position displays
some of the warning and indicator lights.
The battery could be drained if you leave the key in
the ACC/ACCESSORY or ON/RUN position with the
engine off. You may not be able to start your vehicle if the
battery is allowed to drain for an extended period of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER’S DOOR AJAR
when the driver’s door is opened if the ignition is in
LOCK/OFF, ACC/ACCESSORY and the key is in
the ignition. SeeDIC Warnings and Messages on
page 3-52for more information.
2-22

PARK (P):This position locks your front wheels. It is
the best position to use when the engine is started
because your vehicle cannot move easily.
{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 rmly 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 will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 4-27.Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You must fully
apply your regular brakes rst and then press the
shift lever button before you can shift from PARK (P)
while the ignition is in ON/RUN. If you cannot shift out of
PARK (P), ease pressure on the shift lever and push
the shift lever all the way into PARK (P) as you maintain
brake application. Then press the shift lever button
and move the shift lever into another gear. SeeShifting
Out of PARK (P) on page 2-32.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
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,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-20.
2-27

NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
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. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be covered
by your warranty. Be sure the engine is not running
at high speed when shifting your vehicle.DRIVE (D):This position is for normal driving.
It provides the best fuel economy for your vehicle.
If you need more power for passing, and you are:
Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push the
accelerator pedal all the way down.
You will shift down to the next gear and have
more power.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-12.
Notice:Driving your vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transmission. Have your
vehicle serviced right away. You can drive in
SECOND (2) when you are driving less than 35 mph
(55 km/h) and DRIVE (D) for higher speeds until then.
2-28

THIRD (3):This position is also used for normal driving.
However, it reduces vehicle speed more than DRIVE
(D) without using your brakes. You might choose THIRD
(3) instead of DRIVE (D) when driving on hilly, winding
roads, when towing a trailer, so there is less shifting
between gears and when going down a steep hill.
SECOND (2):This position reduces vehicle speed
even more than THIRD (3) without using your brakes.
You can use SECOND (2) on hills. It can help control
your speed as you go down steep mountain roads.
You would also then want to use your brakes off and on.
Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transmission. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or DRIVE (D)
instead of SECOND (2).FIRST (1):This position reduces vehicle speed even
more than SECOND (2) without using your brakes.
You can use it on very steep hills, or in deep snow or
mud. If the shift lever is in FIRST (1) while the vehicle is
moving forward, the transmission will not shift into
rst gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle
in one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.

Parking Brake
The parking brake is
located to the left of the
brake pedal, near the
driver’s door.
To set the parking brake, hold the brake pedal down
with your right foot. Push down the parking brake pedal
with your left foot.
To release the parking brake, hold the brake pedal down
with your right foot and push the parking brake pedal with
your left foot. When you lift your left foot, the parking
brake pedal will follow it to the released position.
A warning chime will sound and a brake warning light
located on the instrument panel cluster will come
on, if the parking brake is set, the ignition is on and the
vehicle speed is greater than 5 mph (8 km/h).Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
If you are towing a trailer and parking on any hill, see
Towing a Trailer on page 4-27.
Shifting Into PARK (P)
{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 rmly 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 will
not move, even when you are on fairly level
ground, use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 4-27.
