STARTING AND OPERATING
percent of engine torqu e to the rear axle. When speed
differences are increased betw een the front and rear drive
shafts, the transfer case can transm it up to 100 percent of
available engine torqu e to the front or rear drive shafts.
Prop er operation of four wheel drive vehicles depend s on
tires of equ al size, typ e, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
When additional traction is requ ired , the 4 LOW position
can be used to lock the front and rear driveshafts together
and force the front and rear wheels to rotate at the sam e
speed . The 4 LOW position is intend ed for loose, slippery
road surfaces only. Driving in the 4 LOW position on dry
hard surfaced road s may cause increased tire wear and
damage to driveline components.
Because four wheel drive provid es improved traction,
there is a tend ency to exceed safe turning and stop ping
speed s. Do not go faster than road cond itions perm it.
When operating you r vehicle in 4 LOW, the engine speed
is approxim ately three times that of the 4 HI position at a
given road speed . Take care not to oversp eed the engine
and do not exceed 25 mph (40 km/ h).
