Use these buttons to shift into and out of four-wheel
drive. You can choose from the following:
m
2 (Two-Wheel High): This setting is for driving in
most street and highway situations. Your front axle is
not engaged in two-wheel drive.
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 2-29.
N (NEUTRAL): Shift the vehicle's transfer case to
NEUTRAL only when towing your vehicle.
m
4 (Four-Wheel High): This setting engages your
front axle to help drive your vehicle. Use four-wheel
high when you need extra traction, such as on snowy
or icy roads, or in most off-road situations.
2-26
n
4 (Four-Wheel Low): This setting also engages
your front axle to give you extra traction. It sends the
maximum power to all four wheels. You might
choose four-wheel low if you were driving off-road in
sand, mud, or deep snow and while climbing or
descending steep hills.
Indicator lights in the buttons show you which setting
you are 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 in
for service. An indicator light will flash while shifting.
It will stay on when the shift is completed.
If for some reason the transfer case does not shift, it will
return to the last chosen setting.
