.If small heavy objects are placed on the roof, cut a
piece of 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.
Rear Seat Armrest
Vehicles with a rear seat armrest have two cupholders.
Pull the armrest down from the rear seatback to access
the cupholders.
Cargo Management System
For vehicles with a cargo management system, it is
located in the bed of the truck. The system contains
three rails located on the front and sides of the bed.
The system has four adjustable cargo tie-downs, that
can be placed on the upper and lower slides of the rail.

If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is bright enough outside. During that
delay, the instrument panel cluster may not be as bright
as usual. Make sure the instrument panel brightness
control is in the full bright position. SeeInstrument
Panel Brightness on page 4‑14.
To idle the vehicle with the automatic headlamp system
off, turn the control to the off position.
The headlamps will also stay on after you exit the
vehicle. This feature can be programmed using the
Driver Information Center (DIC), if equipped. See DIC
Vehicle Customization (With DIC Buttons)
on
page 4‑75.
If the vehicle is not equipped with DIC buttons, exit
lighting is automatic. When it is dark enough outside,
the exterior lamps remain on for 30 seconds after the
ignition is moved from ON/RUN to LOCK/OFF.
For vehicles without a radio, the instrument panel light
remains on for 30 seconds with the driver's door closed.
For vehicles with a radio, the instrument panel light
remains on for 10 minutes with the driver's door closed.
See Retained Accessory Power (RAP) on page 3‑23.
The regular headlamp system can be turned on when
needed.
