h
(2HI): This setting is used for driving in most street
and highway situations. Your front axle is not engaged
in two-wheel drive. This setting also provides the
best fuel economy.
G
(4HI): Use 4HI when you need extra traction, such
a on snowy or icy roads or in most off-road situations.
This setting also engages your front axle to help
drive your vehicle. This is the best setting to use when
plowing snow.
g
(4LO): This setting also engages your front axle
and delivers extra torque. You may never need 4LO.
It sends maximum power to all four wheels. You might
choose 4LO if you are driving off-road in deep sand,
deep mud, deep snow and climbing or descending steep
hills. When operating in 4LO, the gear ratio is extra
deep when compared to 4HI. The transmission gear shift
feel will be exaggerated.

CAUTION:
{
Shifting the transfer case to NEUTRAL
can cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be seriously injured. Be sure to set
the parking brake before placing the transfer
case in NEUTRAL. See Parking Brake on
page 2-49.
NEUTRAL: Shift the vehicle's transfer case to
NEUTRAL only when towing your vehicle. See
Recreational Vehicle Towing on page 4-63 or Towing
Your Vehicle on page 4-62 for more information.
Indicator lights in the switches show which setting your
transfer case is in. The indicator lights will come on
briefly when you turn on the ignition and one will stay on.
If the lights do not come on, you should take your
vehicle to your dealer for service. An indicator light will
flash while the transfer case is being shifted. It will
remain illuminated when the shift is complete. If
for some reason the transfer case cannot make a
requested shift, it will return to the last chosen setting.
