CAUTION!
• Do not attempt to make a shift while only the
front or rear wheels are spinning. The Selec-Trac
transfer case is not equipped with a synchronizer
and therefore the front and rear driveshaft speeds
must be equal for the shift to take place. Shifting
while only the front or rear wheels are spinning
can cause damage to the transfer case.
• When operating your vehicle in 4LO, the engine
speed is approximately three times that of the
2WD, 4 PART TIME, or 4 FULL TIME positions at
a given road speed. Take care not to overspeed the
engine and do not exceed 25 mph (40 km/h).
Proper operation of 4-wheel drive vehicles depends on
tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
can cause damage to the transfer case.
STARTING AND OPERATING 231
WARNING!
• Because 4-wheel drive provides improved trac-
tion, there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than road con-
ditions permit.
• You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging
the parking brake. The transfer case Neutral (N)
position disengages both the front and rear drive-
shafts from the powertrain and will allow the
vehicle to move regardless of the transmission
position. The parking brake should always be
applied when the driver is not in the vehicle.
