Featwes & Contmk
The front axle portion of the indicator diagram will light up when you shift into
four-wheel drive.
A slight delay between shifting and the indicator’s lighting is
normal.
If the indicator does not light up, or if the front axle light does not go
out after you shift out of four-wheel drive, have your dealer check your
system.
When your headlights or parking lights are on, rotate the dial\

to the right of
your headlight switch up
to brighten, or down to dim, your transfer case
indicator light.
Transfer Case Shift Positions
2H (High): This setting is for driving in most street and highway situations.
Your front axle is not engaged in two-wheel drive.
4H (High): This setting engages your front axle to help drive your vehicle.
Use
4H when you need extra traction, such as on wet or icy roads, or in
most
off -road situations.
N (Neutral): Shift to this setting only when your vehicle needs to be towed or
when using a power take
off.
4L (Low): This setting also engages your front axle to give you extra traction,
but should be used only for off-road or on extremely slippery surfaces.
You can shift from
2H to 4H or from 4H to 2H while the vehicle is moving.
Your front axle will engage faster
if you take your foot off of the accelerator
for a few seconds after you shift. In extremely cold weather it may be
necessary to stop or slow the vehicle to shift out of
2H.
To shift into or out of 4L or N (Neutral):
1. Slow the vehicle to a roll, about 3 mph (5 kmlh) and shift your
2. Shift the transfer case shift lever in one continuous motion.
transmission into neutral.
Don’t pause in
N (Neutral) as you shift the transfer case into 4L, or your
aears could clash.
Kernember that driving
in 4H or 4L may reduce fuel economy. Also, driving in
four-wheel drive on dry pavement could cause your tires to wea\
r faster and
make your transfer case harder
to shift.
Front Axle Locking Feature
The front axle locks and unlocks automatically when you shift the transfer
case.
A slight delay for the axle to lock or unlock is normal. If the outside
temperature is very hot, or the vehicle has been used under hard driving
conditions, there may be a slight delay for the axle to unlock.

Turn Signa/ and Lane Change Indicator
(I
The turn signal has two upward (for Right) and two downward \
(for Left)
positions. These positions allow you to signal a turn
or a lane change.
To signal a turn, move the lever all the way up or down. When the turn is
finished, the lever will return automatically.
A green arrow on the instrument panel will flash in the direction of the turn
or lane change.
To signal a lane change, just raise
or lower the lever until the green arrow
starts
to flash. Hold it there until you complete your lane change. The lever
will return by itself when you release it.
As you signal a turn or a lane change, if the arrows flash twice as fast as
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 green
arrows don't go on at all when you signal a turn, check the \
fuse (see "Fuses" in the Index) and for burned-out bulbs.
Operation of Lighfs
Although your vehicle's lighting system (headlights, parking lig\
hts, fog lamps,
side marker lights and taillights) meet all applicable federal \
lighting
requirements, certain states and provinces may apply their own lighting
regulations that may require special attention before you operat\
e these lights.
For example, some jurisdictions may require that you operate your l\
ower

Features & Controls
beam lights with fog lamps at all times, or that headlights b\
e turned on
whenever you must use your windshield wipers.
In addition, most jurisdictions
prohibit driving solely with parking lights, especially at dawn \
or dusk. It is
recommended that you check with your own state or provincial h\
ighway
authority for applicable lighting regulations.
Headight High-Low Beam
- K2242
To change the headlights from low beam to high or high to low, \
pull the turn
signal lever all the way toward you. Then release

are on, this blue light
on the instrument panel also will be on.

You can switch your headlights from high to low beam by pulling o\
n the turn

off. Have your headlight wiring checked
right away
if this happens.
Headlights-On Reminder
A buzzer will sound when your headlights are turned on and your ignition is
in Off, LOCK or Acc.
Fog Lamps
Use your optional fog lamps for better vision in foggy or misty conditions.
Your fog lamps will operate with your low beam headlights or parking li\
ghts
on,
and go off when the high beam headlamps are on. Switching to low
beam headlights or parking lights will let you use the fog la\
mps again.
The fog lamp switch is on the instrument panel below the heating controls.
Press the side of the switch with the fog lamp symbol on
it to turn the fog
lamps on, and the left side of the switch
to turn them off. A light will glow in
the left side of the switch when they are on.
K2294
Remember, fog lamps alone will not give off as much light as your headlights.
Never use your fog lamps in the dark without turning on your headlights.

Daytime Running Lights (DRL) Indicator Light (Canada Only)
K2318
If your vehicle was first sold, when new, in Canada, you will have this light on
the instrument panel. It goes on whenever the Daytime Running \
Lights are on.
Daytime Running Lights (Canada Only)
The Canadian Federal Government has decided that “Daytime Run\
ning
Lights” (DRL) are a useful feature, in that
DRL can make your vehicle more
visible to pedestrians and other drivers during daylight hours. DRL are
required on new vehicles sold in Canada.
The high beam headlights will come on at reduced brightness in daylight
when:
The ignition is on
The headlight switch is off, and
The parking brake is released
When you turn on your headlights, the DRL
will switch off and the exterior
lights will come on. When you turn
off the headlights, the exterior lights will
go out and the high beam lights will switch to the reduced brightness
of DRL
again. The DRL indicator light on the instrument panel will go\
on whenever
the DRL are on. This light means that only the DRL are on. When you turn
on your exterior lights, this light will go out.
Of course, you may still turn on
the headlights any time you need to.
To idle your vehicle with the DRL off, set the parking brake. The DRL will
stay
off until you release the parking brake.
