Electronic Transfer Case
(If
Equipped)
If your four-wheel-drive vehicle has the electronic
transfer case, the transfer case switches are below and
to
the left of the climate control system.
Use these switches to shift into and out
of
four-wheel
drive. You can choose among three driving settings:
.
2HI:
This setting
is
for driving in most street and
highway situations. Your front axle is not engaged
in
two-wheel drive.
4HI:
This setting engages your front axle to help
drive your vehicle. Use
4HI
when you need extra
traction, such as
on
snowy or icy roads, or in most
off-road situations.
4LO:
This setting also engages your front axle to give
you extra traction. You may never need
4LO.
It sends
the maximum power to all four wheels. You might
choose
4LO
if you were driving off-road
in
sand, mud
or deep snow and climbing or descending steep hills.
Indicator lights in the switches show you which setting
you are in. The indicator lights will come
on
briefly
when you turn on the ignition and the last chosen setting
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
remain illuminated when
the shift is completed. If for some reason the transfer
cannot make a requested shift,
it
will return to the last
chosen setting.
