GMC 1996 Jimmy Owner's Manual page 81

To shift into or out of 4LO:
1. The vehicle must be moving less than 3 mph
(4.8 km/h) with the transmission
in
NEUTRAL (N)
for an automatic transmission. For a manual
transmission, the clutch pedal must be engaged.
The preferred method for shifting into or out of
4LO is to have your vehicle moving I to 2 mph
( 1 -6 to 3.2 km/h).
2. Press the transfer case shift button and shift i n one
continuous motion.
Don't pause in N SET PARK BRAKE as you shift into
or out of 4L0, or your gears could clash.
Remember that driving in 4HI or 4LO may reduce
fuel economy.
Also,
driving in four-wheel drive on
dry pavement could cause your tires to wear faster and
make your transfer case harder to shift and reduce
powertrain longevity.
Electronic Transfer Case (Option)
If your four-wheel-drive
vehicle has the electronic
transfer case, the transfer
.. . .
case switches are above
the radio controls.
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 i n 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.
