tow JEEP LIBERTY 2003 Owners Manual

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 (Neu-
tral) for recreational towing.
Shifting Into Neutral (N)
Use the following procedure to prepare your vehicle for
recreational towing.
STARTING AND OPERATING 267

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.
Transmission damage may occur if the automatic
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 steps7±8above).

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
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
Do not use a bumper mounted clamp-on tow bar on
your vehicle. The bumper face bar will be damaged.

Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic
converter and, once the engine has started, ignite and
damage the converter and vehicle.
Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle. Tow straps are recommended
when towing the vehicle, chains may cause vehicle
damage.
WARNING!
Stand clear of vehicles when pulling with tow
hooks. Tow straps and chains may break, causing
serious injury.

Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage
your engine.
