{CAUTION:
If you have a manual transmission removing
the key from the ignition switch will lock the
steering column and result in a loss of ability
to steer the vehicle. This could cause a
collision. If you need to turn the engine off
while the vehicle is moving, turn the key to
ACC/ACCESSORY.
ACC (ACC/ACCESSORY):This position operates
some of your electrical accessories. It unlocks the
steering wheel and ignition.
R(ON/RUN):This is the position the switch returns
to after you start your engine and release the switch.
The switch stays in the ON/RUN position when the
engine is running. But even when the ignition is
not running, you can use ON/RUN to operate your
electrical accessories and to display some 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. When
the engine starts, release the key. The ignition switch
will return to ON/RUN for normal driving.
A warning tone will sound if you open the driver’s door
while in LOCK/OFF or ACC/ACCESSORY, when
the key has not been removed from the ignition.
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.

Column Lock Release
For vehicles with an automatic transmission, the
following procedure allows the ignition to be turned
to LOCK/OFF and ignition key removal in case of a
dead battery or low voltage battery.
1. Make sure the shift lever is in PARK (P).
2. Remove the cover from the bottom of the
steering column.3. Locate the plunger.
4. Press and hold the plunger while turning the
ignition key to LOCK/OFF. Remove the key.
Have your vehicle serviced at your dealer/retailer as
soon as possible.
2-24

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 ACC/ACCESSORY
or LOCK/OFF.
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.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator pedal all
the way to the oor and holding it there as you
hold the key in START for up to a maximum
of 15 seconds. Wait at least 15 seconds between
each try, to allow the cranking motor to cool
down. When the engine starts, let go of the key
and accelerator. If the vehicle starts briey but
then stops again, do the same thing. This clears
the extra gasoline from the engine. Do not race
the engine immediately after starting it. Operate
the engine and transmission gently until the
oil warms up and lubricates all moving parts.
Notice:The engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer/retailer. If you do not, your
engine might not perform properly. Any resulting
damage would not be covered by your vehicle’s
warranty.

Electric Power Management
This vehicle has Electric Power Management (EPM),
an advanced control system. It estimates the battery’s
temperature and state of charge and then adjusts
the voltage for best performance and extended life of
the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or voltage display on the Driver Information
Center (DIC), you may see the voltage move up or
down. This is normal. If there is a problem, an alert will
be displayed.
