RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
CAUTION!
Internal damage to the transfer case will occur if a
front or rear wheel lift is used when recreational
towing.
NOTE: The transfer case must be shifted into N (Neutral)
for recreational towing.
Shifting Into Neutral (N)
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
recreational towing to prevent damage to internal
parts.
1. Depress brake pedal.
2. Shift automatic transmission into N (Neutral) or depress
clutch pedal on manual transmission.
3. Shift transfer case lever into N (Neutral).
4. Start engine.
5. Shift automatic transmission into D (Drive) or manual
transmission into gear.
6. Release brake pedal and ensure that there is no vehicle
movement.
7. Shut the engine off and place the ignition key into the
unlocked OFF position.
8. Shift automatic transmission into P (Park).
9. Apply parking brake.
10. Attach vehicle to the tow vehicle with tow bar.
11. Release parking brake.
CAUTION!
Damage to the transmission may occur if the transmission
is shifted into P (Park) with the transfer case
in N (Neutral) and the engine running. With the
transfer case in N (Neutral) ensure that the engine is
off prior to shifting the transmission into P (Park)
(refer to steps 7 – 8 above).
Shifting Out Of Neutral (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Shift automatic transmission into N (Neutral) or depress
clutch pedal on manual transmission.
2. Shift transfer case lever into desired position.
3. Shift automatic transmission into D (Drive) or release
clutch on manual transmissions.
NOTE: When shifting out of transfer case N (Neutral)
on automatic transmission equipped vehicles, turning
the engine off may be required to avoid gear clash.
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
despite the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
² Do not use a bumper mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
