System (TCS) 0 212.
Indicator lights on the shift control
switch indicate which setting you
are in. The indicator lights will come
on briefly when you turn on the
ignition and the selected setting will
remain on. If the lights do not come
on, you should take the vehicle in
for service. An indicator light will
flash while shifting. It will stay on
when the shift is completed. If the
transfer case does not shift, it will
return to the last chosen setting.
When the ignition key is in the
position 2, the transfer case shift
control module monitors the transfer
case shift control switch to
determine if the driver desires a new
setting. At a turn of the transfer case
shift control switch, the lamp of the
new desired setting will begin to
flash to inform the driver that the
transfer case shift control module
has received the request for a new
setting. The lamp continues to flash
until all shifting criteria has been
met and the new setting has been
reached or has been engaged.
Once the new setting is fully active,
the switch indicator lamp for the
new setting will remain on
constantly.
Note
Continuous driving on 4 or 4 on
high adherence tracks (dry
compacted dirt or paved roads),
mainly on turns or sudden
maneuvers, is not recommended, as
it will cause premature wear of
drivetrain components as well
increasing fuel consumption. It is
always recommended to disable 4
or 4 after its intended usage.

Shifting from Four-Wheel High

or Four-Wheel High to Four-
Wheel Low (2
or 4 to 4 )
To shift from Two-Wheel High 2 or
four-wheel high 4 to four-wheel
low 4 , the vehicle must be stopped
or moving less than 5 km/h with the
transmission in N (Neutral). The

vehicle moving 1.6 to 3.2 km/h .

four-wheel low 4 setting. You must
wait for the four-wheel low 4
