Ignition Positions
Use the key to turn the ignition switch to
five different positions.
C
ACCESSORY (A): This position lets you use things
like the radio and
the windshield wipers when the
engine is
off. Push in the key and turn it toward you.
Your steering wheel will remain locked, just as it was
before you inserted the key.
I NOTICE:
Don’t operate accessories in the ACCESSORY
position for long periods
of time. Prolonged
operation
of accessories in the ACCESSORY
position could drain your battery and prevent
you from starting your vehicle.
LOCK
(B): This position locks your ignition, steering
wheel and transmission.
It’s a theft-deterrent feature.
You will only be able to remove your key when the
ignition is turned to LOCK.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. Use
OFF if you must have
your vehicle in motion while the engine is off (for
example, if your vehicle is being towed).
RUN (D): This is the position for driving.
START (E): This position starts your engine.

NOTICE:
If your key seems stuck in LOCK and you can’t
turn
it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch.
If none of this works, then your
vehicle needs service.
Retained Accessory Power
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow certain features
on your vehicle to continue to work up to
20 minutes
after the ignition key
is turned to OFF.
Your radio, power windows, sunroof and overhead
console will work when the ignition key is in RUN or
ACCESSORY. Once the key is turned from RUN to
OFF, these features will continue to work for up to
20 minutes or until a door is opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position -- that’s a
safety feature.
To restart when you’re already moving,
use NEUTRAL (N) only.
I 1
I NOTICE:
Don’t 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.
1. Without pushing the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as your
engine gets warm.

Locking Rear Axle
Your locking rear axle can give you additional traction
on snow, mud, ice, sand or gravel.
It works like a
standard axle most
of the time, but when one of the rear
wheels has no traction and the other does, this feature
will allow the wheel with traction to move the vehicle.
Four-wheel Drive
Because your vehicle has four-wheel drive, you can
send your engine’s driving power to all four wheels for
extra traction.
To shift out of two-wheel drive and into
four-wheel drive, push the
4HI or 4LO button on the
transfer case switch. You should use
2HI for most
normal driving conditions.
Driving in the 4HI or 4LO positions for a long
time on dry
or wet pavement could shorten the
life
of your vehicle’s drivetrain.
Electronic Transfer Case
The transfer case switches
are above the radio controls.
Use
these switches to shift into and out of four-wheel
drive.
You can choose among three driving settings:
2HI: This setting is for driving in most street and
highway situations. Your front axle is not engaged in
two-wheel drive.
4HI: This setting engages your front axle to help drive
your vehicle. Use
4HI when you need extra traction,
such as on snowy or icy roads, or in most
off-road situations.

Rotate the knob to the right to the master lamps symbol
to turn on all the lamps listed as well as
the headlamps.
Rotate the
knob all the way to the left to turn off your
lamps and put the system in automatic headlamp mode.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be dim.
Your vehicle is equipped with High Intensity Discharge
(€€ID) headlamps. Your headlamps come on at lower
intensity and gradually increase to full brightness.
Your vehicle is equipped with
a light sensor on the top
of the instrument panel under the radio speaker grille,
so
be sure it is not covered, which will cause the system to
be on whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather, a tunnel or fueling your vehicle in a low-light
area. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp systems
so that driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system will only be affected when the light
sensor
sees a change in lighting lasting longer than
the delay.
To idle your vehicle with the automatic headlamp
system
off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps
are manually turned on and your ignition
is in
OFF, LOCK or ACCESSORY. To disable the
chime, rotate the thumb wheel all the way down. In
the
automatic mode, the headlamps turn off once the
ignition key is in
OFF,
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.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows
the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you
if there is an electrical problem. The
system check includes
the air bag sensors, the air bag
module, the wiring and the diagnostic module. For more
information
on the air bag system, see “Air Bag” in
the Index.
This light will come on
when you start your engine,
and
it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may
not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when
you turn the ignition key to RUN. If the
light doesn’t come
on then, have it fixed so it will be
ready to warn
you if there is a problem.
Charging System Indicator Light
The charging system light
will come on briefly when
you turn on the ignition, but
’ the engine is not running,
as a check to show you it
is working.
It should go out once the engine
is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system.
It could indicate that
you have problems with
a generator drive belt, or
another electrical problem. Have
it checked right away.
Driving while this light
is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
