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.

to the right of
your headlight switch up

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.

hts, fog lamps,
