Shifting Out of NEUTRAL
To shift out of NEUTRAL:
1. Set the parking brake and apply the regular brake
pedal.
2. Turn the ignition to RUN with the engine off.
3. Shift the transmission to NEUTRAL (N).
4. Press the button for the desired transfer case
shift position (Two-Wheel High, Four-Wheel
High, AUTO 4WD, or Four-Wheel Low).
5. After the transfer case has shifted out of NEUTRAL
the red light will go out.
6. Release the parking brake.
7. You may start the engine and shift the transmission
to the desired position.Excessively shifting the transfer case into or out of the
different modes may cause the transfer case to enter the
shift protection mode. This will protect the transfer case
from possible damage and will only allow the transfer
case to respond to one shift per 10 seconds. The transfer
case may stay in this mode for up to three minutes.
Electronic Transfer Case
If your four-wheel-drive
vehicle has the electronic
transfer case, the transfer
case switches are located

An arrow on the instrument
panel cluster will ash in
the direction of the turn or
lane change.
As you signal a turn or a lane change, if the arrows
ash more quickly than normal, a signal bulb may
be burned out and other drivers won’t see your turn
signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you signal
a turn, check for burned-out bulbs and a blown fuse.
SeeFuses and Circuit Breakers on page 5-123.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each ash of the turn
signal and the message TURN SIGNAL ON will also
appear in the DIC. To turn the chime and message off,
move the turn signal lever to the off position.
Headlamp High/Low-Beam Changer
53(Headlamp High/Low Beam Changer):To
change the headlamps from low to high beam, push the
lever toward the instrument panel. To return to low-beam
headlamps, pull the multifunction lever toward you. Then
release it.
When the high beams are
on, this indicator light on
the instrument panel
cluster will also be on.
3-8

Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass. It
works even if your headlamps are in the automatic
position.
To use it, pull the turn signal lever toward you, then
release it.
If your headlamps are in the automatic position or on
low beam, your high-beam headlamps will turn on.
They’ll stay on as long as you hold the lever toward
you. The high-beam indicator on the instrument panel
cluster will come on. Release the lever to return to
normal operation.
Windshield Wipers
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
gently loosen or thaw them. Damaged wiper blades
may not clear the windshield well, making it harder to
see and drive safely. If the blades do become damaged,
install new blades or blade inserts. For more information,
seeWindshield Wiper Blade Replacement on page 5-71
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.You control the windshield wipers by turning the band
with the wiper symbol on it.
8(Mist):For a single wiping cycle, turn the band to
mist. Hold it there until the wipers start. Then let go. The
wipers will stop after one wipe. If you want more wipes,
hold the band on mist longer.
N(Delay):You can set the wiper speed for a long or
short delay between wipes. This can be very useful in
light rain or snow. Turn the band to choose the delay
time. The closer to the top of the lever, the shorter
the delay.
6(Low Speed):For steady wiping at low speed,
turn the band away from you to the rst solid band past
the delay settings. For high-speed wiping, turn the band
further, to the second solid band past the delay settings.
To stop the wipers, move the band to off.
1(High Speed):For high-speed wiping, turn
the band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.

Your vehicle is equipped with a light sensor located on
the top of the instrument panel in the defroster grille.
Be sure it is not covered, or the system will be on
whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. 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.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take approximately one minute for
the automatic headlamp system to change to DRL if it is
bright enough outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make sure
your instrument panel brightness control is in the full
bright position. SeeInstrument Panel Brightness on
page 3-18.To idle your vehicle with the automatic headlamp
system off, turn the control to the off position.
You may be able to turn off your Automatic Headlamp
System. SeeDaytime Running Lamps (DRL) on
page 3-15for more information.
Your headlamps will also stay on after you exit the
vehicle. You can program this feature using the Driver
Information Center (DIC). SeeDIC Vehicle Customization
on page 3-64.
As with any vehicle, you should turn on the regular
headlamp system when you need them.
3-16

Dome Lamp Override
E(Dome Lamp Override):You can use the dome
override button, located below the exterior lamps control,
to set the dome lamps to come on automatically when a
door is opened, or to remain off. To turn the lamps off,
press the button into the in position. With the button in
this position, the dome lamps will remain off when the
doors are open. To return the lamps to automatic
operation, press the button again and return it to the
out position. With the button in this position, the dome
lamps will come on when you open a door.
Entry Lighting
Your vehicle is equipped with an illuminated entry
feature.
When the doors are opened, the dome lamps will come
on if the dome override button is in the out position. If the
dome override button is pressed in, the lamps will not
come on.
Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition. The lights will
not come on if the dome override button is pressed in.
Front Reading Lamps
The reading lamps are located on the overhead console.
To turn on the reading lamps, press the button located
next to each lamp. To turn them off, press the button
again.
The lamps can be adjusted to point in the direction
you want.
Your vehicle may also have reading lamps in other
locations. To turn the lamps on or off, press the button
located next to the lamp. The lamps are xed and cannot
be adjusted.
Cargo Lamp
The cargo lamp button is
located on the left side of
the instrument panel. Press
the button to turn the cargo
lamp on. Press the button
again to turn it off.

Instrument Panel Cluster
Your instrument cluster is designed to let you know at a glance how your vehicle is running. You will know how fast
you are going, about how much fuel you have and many other things you will need to know to drive safely and
economically.
