2. The front tires must be properly
inflated. If necessary, move a
rear tire to the front to replace a
flat or damaged tire.
3. Place a 1.2 m (4 ft) X 102 mm
(4 in) X 102 mm (4 in) wood
beam (4) under the front cradle
crossmember (3), and on top of
both tow chains (5) to ensure the
tow chains do not come into
contact with the front fascia (1).
Try to minimize the contact of
the chains with the flexible
air dam (2).
4. Ramps (2) are required for the
front fascia (3) to clear the
flatbed (1). The ramp height
should be approximately 102 mm
(4 in). Lower the flatbed onto the
set of ramps.
5. After the front tires are on the
flatbed adjust the flatbed upward
to provide additional clearance
between the air dam, fascia, and
flatbed.
6. When the fascia has enough
clearance to clear the flatbed,
lower the flatbed, and finish
pulling the vehicle onto the
flatbed.
7. Secure the vehicle to the
flatbed (2) using nonabrasive
straps (1) through all four wheel
openings and secure the straps
to the flatbed (2).
