This position locks the ignition. It also locks the
transmission and steering column. This is the only
position in which the ignition key can be inserted or
removed.
Do not turn the engine off when the vehicle is moving.
This will cause a loss of power assist in the brake and
steering systems and disable the airbags.
In an emergency:1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This may deplete
power assist, requiring increased brake pedal
force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving. After shifting to
N (Neutral), firmly apply the brakes and steer the
vehicle to a safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition to LOCK/OFF. On vehicles with
an automatic transmission, the shift lever must
be in P (Park) to turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake
on
page 3‑26. The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from right to
left while turning the key to ACC/ACCESSORY. If this
doesn't work, then the 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 can be used to operate
electrical accessories and to display some of the
warning and indicator lights. The switch stays in this
position when the engine is running.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle if
the battery is allowed to drain for an extended period
of time.
D (START): This position starts the engine. When the
engine starts, release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound and the Driver Information
Center (DIC) will display DRIVER DOOR OPEN when
the driver door is opened if the ignition is in LOCK/OFF,
ACC/ACCESSORY and the key is in the ignition. See
DIC Warnings and Messageson page 4‑49for more
information.

Retained Accessory Power (RAP)
The following accessories can be used for up to
10 minutes after the engine is turned off.
.Audio System
.Audio Steering Wheel (if equipped)
.Clock
.Power Windows
.Sunroof (if equipped)
Power to these accessories works up to 10 minutes or
until the driver door is opened.
The instrument panel cluster lights stay on for a few
seconds, then will go out. Once the driver door is
opened, the power shuts off to these accessories. The
vehicle has a feature designed to protect the battery
against drainage. For more information see Inadvertent
Power Battery Saver
on page 4‑14and Electric Power
Management on page 4‑14.
Starting the Engine
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart
the engine when the vehicle is already moving, use
N (Neutral) only. Notice:
Do not try to shift to P (Park) if the vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when the vehicle
is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition to START. When the engine starts, let
go of the key. The idle speed will slow down
as the engine warms. Do not race the engine
immediately after starting it. Operate the engine
and transmission gently to allow the oil to warm up
and lubricate all moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is
turned to the START position, and then released
when the engine begins cranking, the engine will
continue cranking for a few seconds or until the
vehicle starts. If the engine does not start and the
key is held in START, cranking will be stopped
after 15 seconds to prevent cranking motor
damage. To prevent gear damage, this system also
prevents cranking if the engine is already running.

Automatic Transmission Operation
The vehicle may have a shift lever located either on the
steering column or on the console between the seats.
P (Park):This position locks the front wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park
on page 3‑27. If you are pulling a trailer,
see Towing a Trailer on page 5‑25.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to
fully apply the regular brakes before you can shift from
P (Park) while the ignition is in ON/RUN. If you cannot
shift out of P (Park), ease pressure on the shift lever
and push the shift lever all the way into P (Park) as you
maintain brake application. Then move the shift lever
into the gear you want. See Shifting Out of Park
on
page 3‑28.
R (Reverse): Use this gear to back up.
