4WD GMC JIMMY 2000 Owner's Manual

2-29 Automatic Transfer Case (If Equipped)
The transfer case switches
are to the right of the
steering wheel on the
instrument panel. Use these
switches to shift into and
out of four
-wheel drive.
You can choose among four
driving settings:
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.
AUTO 4WD: This setting is ideal for use when road
conditions are variable. When driving your vehicle in
AUTO 4WD, the front axle is engaged, but the vehicle's
power is sent only to the rear wheels. When the vehicle
senses a loss of traction, the system will automatically
engage four
-wheel drive. Driving in this mode results in
slightly lower fuel economy than 2HI.

2-30
4HI: Use 4HI when you need extra traction, such as on
snowy or icy roads or in most off
-road situations.
This setting also engages your front axle to help drive
your vehicle.
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.
CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the transmission
is in PARK (P), or if you have a manual
transmission, even if you are in gear. You or
someone else could be seriously injured. Be sure
to set the parking brake before shifting the
transfer case to NEUTRAL. See ªParking Brakeº
in the Index.
NEUTRAL: Shift the vehicle's transfer case to
NEUTRAL only when towing your vehicle. See
ªRecreational Vehicle Towingº or ªTowing Your
Vehicleº in the Index for more information.
Indicator lights in the switches show 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
to your dealer for service. An indicator light will
flash while shifting the transfer case. 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.
If the SERVICE 4WD light stays on, you should take
your vehicle to your dealer for service. See ªService
4WDº in the Index for further information.
Shifting to 4HI or AUTO 4WD

This can be done at any speed, and the indicator light
will flash while shifting. It will remain illuminated when

Shifting to 4LO
To shift to 4LO, the vehicle's engine must be running
and the vehicle must be stopped or moving less
than 3 mph (4.8 km/h) with the transmission in
NEUTRAL (N) or with the clutch pedal pressed for

method for shifting into 4LO is to have your vehicle
moving 1 or 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 less than 3 mph (4.8 km/h) and the
transmission is in NEUTRAL (N) or with the clutch
pedal pressed for vehicles with manual transmission.
After 30 seconds, the transfer case will return to the
setting last chosen.Shifting Out of 4LO

vehicle must be stopped or moving less than 3 mph
(4.8 km/h) with the transmission in NEUTRAL (N), or
with the clutch pedal pressed for vehicles with manual
transmission, and the engine running. The preferred
method for shifting out of 4LO is to have your vehicle
moving 1 or 2 mph (1.6 to 3.2 km/h). Press and release
the 4HI, AUTO 4WD or 2HI switch. You must wait for
the 4HI, AUTO 4WD or 2HI indicator light to stop
flashing and remain illuminated before shifting your
transmission into gear.
If the 4HI, AUTO 4WD or 2HI switch is pressed
when your vehicle is in gear and/or moving, the 4HI,
AUTO 4WD or 2HI indicator light will flash for
30 seconds but will not complete the shift unless your
vehicle is moving less than 3mph (4.8 km/h) with the
transmission in NEUTRAL (N) or with the clutch pedal
pressed for vehicles with manual transmission.
