Your vehicle is equipped with
removable Recovery Hitches,
designed for short distance recovery
purposes only. Use only the provided
hitches, according the following
instructions. When using this
connection, do not transport your
vehicle over long distances. (If your
vehicle does not have the proper
hitches, contact your dealer.)
All lubricating and clutch application
oil pressure is provided by an
engine-driven pump, which will not
work when the engine is stopped.
You could seriously damage your
vehicle by towing it with the driveline
connected and the drive wheels on
the ground. Worse, when vehicles are
towed, either by wrecker or piggyback,

the lubricant in the top front of the
drive axle will drain to the rear. This
will leave the top components dry. The
resulting friction may damage them.
Always remove the main drive axle
shafts before towing your vehicle.
CAUTION
Remove the drive axle shafts or lift the
driving wheels off the ground before
towing the vehicle. Towing the vehicle
with either the wheels on the ground or
the axle shafts in the axles will cause
damage to the axle gears.
CAUTION
If your vehicle has a Meritor axle with a
driver-controlled main differential lock,
install the caging bolt before removing
the axles for towing, see Driver Con-
trolled Main Differential Lock on page
2-16. Installing the caging bolt pre-
vents damage by locking internal axle
components in position.

CAUTION
Connect only to the Recovery Hitches,
see Vehicle Recovery Guidelines on
page 2-12. Connections to other struc-
tural parts could damage the vehicle.
Do not attach to bumpers or brackets.
Use only equipment designed for this
purpose. Failure to comply may result
in equipment damage.
