From owners manual:
With the switch set to the AUTO position,
distribution of torque to the front and rear
wheels changes automatically, depending
on road conditions encountered [ratio; 0 :
100 (2WD) ! 50 : 50 (4WD)]. This results
in improved driving stability
c Never shift the 4WD shift switch between
4LO and 4H while driving.
c The 4H position provides greater traction.
Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could
damage drivetrain components.
Speeds over 62.5 MPH (100 km/h) in 4H
is not recommended.
c The 4LO position provides maximum
power and traction. Avoid raising vehicle
speed excessively, as the maximum
speed is approximately 31 MPH
c When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or reversing.
c Do not shift the 4WD shift switch (between
2WD, AUTO and 4H) while driving
on steep downhill grades. Use the engine
brake and low automatic transmission
gears (D1 or D2) for engine
