Use the four–wheel drive control switch
knob and center differential lock switch
to select the transfer and center differ-
ential modes.
The "H4" and "L4" positions of the four–
wheel drive control switch knob provide
either lock or unlock mode of the center
differential depending on the center differ-
ential 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 skid control system is
automatically turned off and the center dif-
ferential lock and "VSC OFF" indicator
lights come on because the function that
controls engine performance interferes
with the process of freeing your wheels.
NOTICE
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
Make sure that the center differential
lock indicator light and vehicle skid
control system off indicator light turn
off.
"H4" (high speed position, center differ-
ential unlocked): Four–wheel drive control
switch knob at "H4", 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.
"H4" (high speed position, center differ-
ential locked): Four–wheel drive control
switch knob at "H4", 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.
