Jeep 2006 Grand Cherokee - Manual (Page 172)

NOTE: The optional cross rails have seven specific
locations identified by a feature on both the side rail and
the cross rail. Cross rails must be secured in one of the
seven detent locations on the side rail to prevent move-
ment with a sudden stop. For improved windnoise
performance when cross rails are not in use, place them
in detent positions #2 (second detent from the front of the
vehicle) and #7 (detent closest to the rear of the vehicle)
as indicated with a unique feature on the side rails.
CAUTION!
•
To prevent damage to the roof of your vehicle, DO NOT
carry any loads on the roof rack without cross rails
installed. The load should be secured and placed on top
of the cross rails, not directly on the roof. If it is
necessary to place the load on the roof, place a blanket
or some other protection between the load and the roof
surface.
•
To avoid damage to the roof rack and vehicle, do not
exceed the rated load capacity of your cross rail system
or the roof rack system maximum load capacity of 150
lbs (68 kg). Always distribute heavy loads as evenly as
possible and secure the load appropriately.
•
Long loads which extend over the windshield, such as
wood panels or surfboards, should be secured to both
the front and rear of the vehicle.
•
Travel at reduced speeds and turn corners carefully
when carrying large or heavy loads on the roof rack.
Wind forces, due to natural causes or nearby truck
traffic, can add sudden upward loads. This is especially
true on large flat loads and may result in damage to the
cargo or your vehicle.
