RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Recreational Towing 2WD Models
Recreational towing of 2WD models is not allowable.
Towing the vehicle with the transmission in NEUTRAL
can cause severe transmission damage. Removal of the
driveshaft for towing is not recommended since this
allows transmission fluid to leak out.
Recreational Towing 4WD Models
CAUTION!
Vehicles equipped with an NV 140 Transfer Case
(which has no NEUTRAL position) may NOT be
used for recreational towing.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
despite the transmission position. The parking brake
should always be applied when the driver is not in
the vehicle.
CAUTION!
Internal damage to the transfer case will occur if a
front or rear wheel lift is used when recreational
towing.
