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.
ACC (ACC/ACCESSORY):This position allows things
like the radio and windshield wipers to operate while
the engine is off.
R(ON/RUN):This position is where the key returns
to after the vehicle is started. With the engine off,
the ON/RUN 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.
/(START):This position starts the engine. Let go
of the key when the engine starts. The key will return
to the ON/RUN for normal driving.
A continuous warning chime will sound and a KEY IN
IGNITION message will display on the Driver Information
Center (DIC) if the key is turned to LOCK/OFF or
ACC/ACCESSORY and the driver’s door is opened.
Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s door.
Always remember to remove your key from the ignition
and take it with you. This will lock your ignition and
transmission. Also, always remember to lock the doors.
The battery could be drained if you leave the key in
the ignition while your vehicle is parked. You may not
be able to start your vehicle after it has been parked
for an extended period of time.
Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
Sunroof (if equipped)
Power to these features will continue to operate for
up to 10 minutes after the key is turned to LOCK/OFF
until a door is opened.

Starting the Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position – this is a
safety feature. To restart when you are already moving,
use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm. 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.Your 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 for many seconds, 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.
Engine cranking can be stopped by turning the
ignition switch to the ACC/ACCESSORY or
LOCK/OFF position.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.

Torque Lock
If you are parking on a hill and you do not 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 nd 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 nd out how, seeShifting Into PARK (P)
on page 2-34.
When you are ready to drive, move the shift lever out
of PARK (P)beforeyou release the parking brake.
If torque lock does occur, you may need to have another
vehicle push your vehicle 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)
This vehicle has an electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal unless the shift lever is
in PARK (P) with the shift lever button fully released,
and
Prevent movement of the shift lever out of PARK (P),
unless the ignition is in ON/RUN and the regular
brake pedal is applied.
The shift lock release is always functional except in the
case of an uncharged or low voltage (less than 9 volt)
battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-46for more
information.
To shift out of PARK (P) use the following:
1. Apply the brake pedal.
2. Press the shift lever button.
3. Move the shift lever to the desired position.
