GMC SONOMA 2004 Owner's Manual

You can adjust the crossrails to handle loads of various
sizes. Just loosen the slider knobs at each end of
the crossrail and move them to where you want them.
Make sure both sides of the crossrails are even,
then tighten the slider knobs.
Be sure the cargo is properly loaded. Follow these
guidelines:
•Carrying small, heavy loads on the roof is not
recommended.
•Secure the load using the tie downs at both ends of
the crossrails. When loading cargo directly on the
roof panel, use the crossrails to keep the load from
shifting.
•If you need to carry long items, move the crossrails
as far apart as possible. Tie the load to the tie
downs provided. Also tie the load to the bumpers.
Do not tie the load so tightly that the crossrails
or side rails are damaged.
Notice:Loading cargo on the luggage carrier that
weighs more than 100 lbs. (45 kg) or hangs over the
rear or sides of the vehicle may damage your
vehicle. Load cargo so that it rests on the slats as
far forward as possible and against the side
rails, making sure to fasten it securely.Don’t exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading seeLoading Your Vehicle on
page 4-45.
To prevent damage or loss of cargo as you’re driving,
check now and then to make sure the luggage
carrier and cargo are still securely fastened.
Bed Rails
{CAUTION:
If your vehicle has bed rails, they are there for
appearance only. If you try to tie down a load
with them, or to secure things in your truck,
not only can it damage the bed rails, but the
load can loosen. This could cause injury to
you or others. Secure loads by using the cargo
tie-down loops, inside the truck bed area.

Sunroof
If your vehicle has a
sunroof, the switch is
located between the sun
visors.
The sunroof switch will only work when the ignition is on
or when the ignition is off and retained accessory
power is active. See “Retained Accessory Power” under
Ignition Positions on page 2-17for more information.To operate the sunroof using the power switch do the
following:
1. When vent opening the sunroof press and hold the
side of the switch with the roof symbol on it until the
roof is vented.
2. Press and hold the side of the switch with the roof
symbol on it again to fully open the roof. The roof
will stop when it is fully opened.
Releasing the switch at any time will stop the roof
at that position.
3. To close the sunroof press the side of the switch
opposite of the roof symbol and hold it until the
glass panel is seated.
2-42

Manually Closing the Sunroof
If you are unable to operate the sunroof using the
switch, check the fusible link under the dashboard.
Your vehicle, when new, came with a tool for manually
operating the sunroof. See your dealer if you cannot
locate this tool in your vehicle.
To manually close the sunroof do the following:
1. Use a flat bladed tool to remove the cover.2. Insert the key and turn to the right.
