WARNING
Always wait for the gear change process from
HIGH RANGE to LOW RANGE – and from LOW
RANGE to HIGH RANGE – to complete. Do not
turn off the engine while changing gear and
do not switch the automatic transmission to
another gear.
If you do not wait for the gear change process
to complete, it may not be correctly imple-
mented. The transfer case may then be in
neutral and the connection between the
engine and the drive axles may be disen-
gaged. The vehicle could then move freely,
even if a gear is engaged, and could inadver-
tently start moving, particularly if it is on a
slope.
