CAUTION:
{
Shifting the transfer case to NEUTRAL
can cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be seriously injured. Be sure to set
the parking brake before placing the transfer
case in NEUTRAL. See Parking Brake on
page 2-37.
NEUTRAL: Shift the vehicle's transfer case to
NEUTRAL only when towing your vehicle. See
Recreational Vehicle Towing on page 4-46 or Towing
Your Vehicle on page 4-46 for more information.
Indicator lights in the buttons show which setting you
are in. The indicator lights will come on briefly when you
turn on the ignition and one will stay on. If the lights
do not come on, you should take your vehicle to your

shifting the transfer case. It will remain illuminated when
the shift is complete. If for some reason the transfer
case cannot make a requested shift, it will return to the
last chosen setting.
If the SERVICE 4WD light stays on, you should take
your vehicle to your dealer for service. See Service
Four-Wheel Drive Warning Light on page 3-35 for further
