EXTERIOR FEATURES
Roof rack (if equipped)
ONX4050057
Your vehicle may come equipped with
roof rack rails. If your vehicle is equipped
with roof rack rails, you may be able to
add roof rack crossbars as an accessory
(not shown).
NOTICE
If the vehicle is equipped with a
sunroof, be sure not to position cargo
onto the roof side rails in such a way
that it could interfere with sunroof
operation.
NOTICE
• When carrying cargo on the roof side
rails, take the necessary precautions
to make sure the cargo does not
damage the roof of the vehicle.
• When carrying large objects on the
roof side rails, make sure they do
not exceed the overall roof length or
width.
WARNING
• The following specification is the
maximum weight that can be loaded
onto the roof side rails. Distribute the
load as evenly as possible onto the
roof side rails and secure the load
firmly.
Loading cargo or luggage in excess
of the specified weight limit on the
roof side rails may damage your
vehicle.
ROOF SIDE
RAILS 220 lbs. (100 kg)
EVENLY DISTRIBUTED
• The vehicle center of gravity will be
higher when items are loaded onto
the roof side rails. Avoid sudden
starts, braking, sharp turns, abrupt
maneuvers or high speeds that may
result in loss of vehicle control or
rollover resulting in an accident.
• Always drive slowly and turn corners
carefully when carrying items on the
roof side rails. Severe wind updrafts,
caused by passing vehicles or natural
causes, can cause sudden upward
pressure on items loaded on the
roof side rails. This is especially true
when carrying large, flat items such
as wood panels or mattresses. This
could cause the items to fall off the
roof side rails and cause damage to
your vehicle or others around you.
• To prevent damage or loss of cargo
while driving, check frequently
before or while driving to make sure
the items on the roof side rails are
securely fastened.
