front or rear wheels are spinning can cause damage to the
transfer case.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD or
4WD LOCK positions at a given road speed. Take care
not to overspeed the engine and do not exceed 40 km/h
(25 mph).
Proper operation of four-wheel-drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
WARNING!
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 driveshafts 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.
