Before storing the cargo panels,
make sure that the latches on
the cargo panels are in the
locked position. The latches are
locked when they are parallel to
the front and back edge of the
panel.

Cargo Tie-Downs
The vehicle has cargo tie downs,
located in the rear cargo area.
These can be used to secure cargo.
The tie downs can also be used to
secure the cargo cover panel strap
system, if the vehicle has one. For
more information seeCargo Cover
Panels on page 4‑5.
Roof Rack System
{WARNING
If something is carried on top of
the vehicle that is longer or wider
than the roof rack —like paneling,
plywood, or a mattress —the
wind can catch it while the vehicle
is being driven. The item being
carried could be violently torn off,
and this could cause a collision
and damage the vehicle. Never
carry something longer or wider
than the roof rack on top of the
vehicle unless using a GM
certified accessory carrier.
For vehicles with a roof rack, the
rack can be used to load items. For
roof racks that do not have
crossrails included, GM Certified
crossrails can be purchased as an
accessory. See your dealer for
additional information. Notice:
Loading cargo on the
roof rack that weighs more than
91 kg (200 lbs) or hangs over the
rear or sides of the vehicle may
damage the vehicle. Load cargo
so that it rests evenly between
the crossrails, making sure to
fasten cargo securely.
To prevent damage or loss of cargo
when driving, check to make sure
crossrails and cargo are securely
fastened. Loading cargo on the roof
rack will make the vehicle’ s center
of gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden
braking or abrupt maneuvers,
otherwise it may result in loss of
control. If driving for a long distance,
on rough roads, or at high speeds,
occasionally stop the vehicle to
make sure the cargo remains in its
place.

4-12 Storage
Do not exceed the maximum vehicle
capacity when loading the vehicle.
For more information on vehicle
capacity and loading, seeVehicle
Load Limits on page 9‑15.
.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.

Engine Oil Pressure Light
Notice:Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty.
Check the oil level as soon as
possible. Add oil if required, but
if the oil level is within the
operating range and the oil
pressure is still low, have the
vehicle serviced. Always follow
the maintenance schedule for
changing engine oil.
This light comes on briefly while
starting the engine. If it does not,
have the vehicle serviced by your
dealer. If the system is working
normally, the indicator light then
goes off. If the light comes on and stays on, it
means that oil is not flowing through

information. When fuel is added this
light and message should go off.
If they do not, have the vehicle

indicator light turns off. If it does not
come on, have the vehicle serviced
by your dealer.
If the light stays on and the engine
does not start, there could be a
problem with the theft-deterrent
system.
This light is also used to indicate the
