STARTING AND DRIVING

FOUR WHEEL DRIVE SYSTEM

(a) Four wheel drive control
Use the four wheel drive control lever and center
differential lock switch to select the following transfer and
center differential modes.
The "H" and "L" position of the four wheel drive control lever
provides either lock or unlock mode of the center differential
depending on the center differential lock switch position.
Use the center differential lock system if your wheels get stuck
in a ditch, or when you are driving on a slippery or bumpy
surface. When the center differential is locked, the vehicle
stability control system is automatically turned off and the
center differential lock and "VSC OFF" indicator lights come on
because the function that controls engine performance
interferes with the process of freeing your wheels.
356
As soon as the center differential lock switch is turned
on, the "VSC OFF" indicator light comes on. After the
wheels are out of the ditch or off the slippery or bumpy
surface, turn the center differential lock switch off.
Make sure the center differential lock indicator light and
vehicle stability control system off indicator light turn
off.
"H" (high speed position, center differential unlocked):
Lever at "H", center differential lock switch left out
Use this for normal driving on all types of roads, from dry
hard surfaced roads to wet, icy or snow covered roads. This
position gives greater economy, quietest ride, least wear and
better vehicle control.
"H" (high speed position, center differential locked): Lever
at "H", center differential lock switch pushed in
Use this for greater traction when you experience a loss of
power, such as wheel slipping, in the center differential unlock
mode.
"N" (neutral position): Lever at "N"
No power is delivered to the wheels. The vehicle must be
stopped.
