RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
CAUTION!
Front or rear wheel lifts should not be used. Internal
damage to the transmission or transfer case will occur
if a front or rear wheel lift is used when recreational
towing.
Two-Wheel Drive Models
Recreational towing is allowed ONLY if the rear drive-
shaft is removed. See your authorized dealer or refer to
the Service Manual.Towing with the rear wheels on the
ground while the driveshaft is connected can result in
severe transmission damage.
WARNING!
If the driveshaft is removed, the vehicle can roll even
if the transmission is in PARK, which could cause
serious injury or death.
The parking brake must be firmly engaged and the
wheels chocked during driveshaft removal and installa-
tion. The parking brake must remain engaged unless the
vehicle is securely and properly connected to the tow
vehicle, or the driveshaft is completely reinstalled. See
your authorized dealer for proper driveshaft removal
and reinstallation procedures, including flange
orientation/alignment, use of thread-locking compound,
proper bolt torque specifications, etc.

tral), automatic transmission must be shifted into PARK,
and manual transmission must be placed in gear (not in
NEUTRAL) for recreational towing.

WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle. Use the following procedure to prepare your vehicle for
recreational towing.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in N (Neutral) before recre-
ational towing to prevent damage to internal parts.
1. Turn the engine off.
2. Press the brake pedal.
3. Shift the automatic transmission into NEUTRAL or
press the clutch pedal on a manual transmission.
4. Shift the transfer case lever into N (Neutral).
