.If small heavy objects are placed
on the roof, cut a piece of 9 mm
or 3/8 inch plywood to fit inside
the crossrails and siderails to
spread the load. Tie the plywood
to the siderail supports.
.Tie the load and secure it to
the crossrails or the siderail
supports. Use the crossrails only
to keep the load from sliding. To
move a crossrail, lift the release
lever up, on both sides of the
rail. Then slide the crossrail to
the desired position balancing
the force side to side. Press the
release lever down on both
sides of the rail, down to tighten
it. Try to slide the crossrail back
and forth slightly to make sure it
is tight.
.To carry long items, move the
crossrails as far apart as
possible. Tie the load to the
crossrails and the siderails or
siderail supports. Also tie the
load to the bumpers, but do not
tie the load so tightly that the
crossrails or siderails are
damaged.
.After moving a crossrail, be sure
it is securely locked into the
siderail.
A Center High-Mounted Stoplamp
(CHMSL) is located above the rear
window glass.
Make sure items loaded on the roof
of the vehicle do not block or
damage the CHMSL.

installation instructions included
with the equipment. Do not use
equipment exceeding the
maximum amperage rating of
