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 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 remain illuminated when the shift
is completed.
Shifting from 2HI to 4HI
Press and release the 4HI switch. This can be done at any
speed, and the indicator light will flash while shifting.
It
will remain illuminated when the shift is completed.
Shifting from 4HI to 2HI
Press and release the 2HI switch. This can be done at
any speed, and the system will unlock automatically.
Shifting from 2HI or 4HI to 4LO
To shift from 2HI or 4HI to 4L0, the vehicle must be
stopped or moving less than 3 mph (4.8 km/h) with the
transmission
in
NEUTRAL (N). The preferred method
for shifting into 4LO is to have your vehicle moving
1 to 2 mph (1.6 to 3.2 km/h). Press and release the
4LO switch. You must wait for the 4LO indicator light
to stop flashing and remain illuminated before shifting
your transmission into gear.
If the 4LO switch is pressed
when
your vehicle is in
gear and/or moving, the 4LO indicator light will flash
for 30 seconds and not complete the shift unless your
vehicle is moving slower than 3 mph (4.8 k d h ) and the
transmission is in NEUTRAL (N).
