You can carry wide building materials (sheets of ply-
wood, etc.) by building a raised load floor. Place lumber
across the box in the indentations provided above the
wheel housings and in the bulkhead dividers to form the
floor.
WARNING!
The pickup box is intended for load carrying pur-
poses only, not for passengers, who should sit in
seats and use seat belts.
WARNING!
•Care should always be exercised when operating a
vehicle with unrestrained cargo. Vehicle speeds may
need to be reduced. Severe turns or rough roads may
cause shifting or bouncing of the cargo that may
result in vehicle damage. If wide building materials
are to be frequently carried, the installation of a
support is recommended. This will restrain the
cargo and transfer the load to the pickup box floor.
•If you wish to carry more than 600 lbs (272 kg) of
material suspended above the wheelhouse, sup-
ports must be installed to transfer the weight of
the load to the pickup box floor or vehicle damage
may result. The use of proper supports will permit
loading up to the rated payload.
•Unrestrained cargo may be thrown forward in an
accident causing serious or fatal injury.

There are stampings in the sheet metal on the inner side
bulkheads of the box in front of and behind both wheel
housings. Place wooden boards across the box from side
to side to create separate load compartments in the
pickup box.
There are four tie-down cleats bolted to the lower sides of
the pickup box that can sustain loads up to 1000 lbs (450
kg) total.
SLIDE-IN CAMPERS
Camper Applications
Certain truck models are not recommended for slide-in
campers. To determine if your vehicle is excluded, please
refer to the “Consumer Information Truck-Camper Load-
ing” document available from your dealer. For safety
reasons, follow all instructions in this important docu-
ment. NOTE:
When a cap or pickup camper is installed on a
vehicle, an alternate CHMSL (Center High Mounted Stop
Light) must be provided.
EASY-OFF TAILGATE
To simplify mounting of a camper unit with an overhang,
the tailgate can be removed quickly. If the truck is a 3500
dual rear wheel model, unplug the tailgate wire harness
from under the rear of the truck and pull the harness out
of the cargo box access hole. Unlatch the tailgate and
remove the support cables by releasing the lock tang
from the pivot, then rotate and pull away from the box.
Once the cables are free, move to the right side of the
tailgate hinge bracket.
Raise the right side of the tailgate until the right side
pivot clears the hanger bracket. Slide the entire tailgate to
the right to free the left side pivot. Remove the tailgate
from the vehicle entirely. Do not carry the tailgate loose in
the truck pickup box.

NOTE:Dual rear wheel pickup models require properly
spaced rear clearance lights. If such a vehicle is operated
without a tailgate, suitable lights must be installed.

CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
18. Brake System Warning Light
This light illuminates when the ignition key is turned to
the ON position and remains on for a few seconds. If the
light stays on longer, it may be an indication that the
parking brake has not been released. This light will
illuminate if the brake fluid is low, especially when
braking or accelerating hard. This light will illuminate if
the ABS indicator light has a malfunction. This light will
flash if the engine is running and the parking brake is on. If the light remains on when the parking brake is
released, it indicates a possible brake hydraulic system
malfunction. In this case, the light will remain on until
the cause is corrected.
If brake failure is indicated, immediate repair is necessary
and continued operation of the vehicle in this condition is
dangerous.
Acceleration which causes the rear wheels to slip for a
period of time may result in the red brake light illumi-
nating and a brake switch code being set on ABS
equipped vehicles. Depressing the brake pedal should
extinguish the red brake light.
19. ABS Warning Light
This light monitors the Anti-Lock Brake System
which is described elsewhere in this manual. This
light will come on when the ignition key is turned to the
ON position and may stay on for five seconds. If the ABS
light remains on or comes on during driving, it indicates

24. Low Washer Fluid Light
This light comes on when the washer fluid level falls
below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled.
25. Transmission Oil Temperature Warning Light
(Automatic Transmissions Only)This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g. snow plowing, off- road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off. 26. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.
27. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.
28. Low Fuel Warning Light
When the fuel level drops to 1/16 tank, the fuel
symbol will light and a single chime will sound.
(See page 178 for more information.)
NOTE: If your vehicle is equipped with an overhead
console module (CMTC), it is possible for DTE to display
“LO FUEL” before the low fuel warning light turns on in
the instrument cluster. This could occur because the low
fuel warning is set to a specified fuel tank volume and
DTE is an estimated distance calculation based on vehicle
fuel economy and remaining fuel tank volume.

Reception Quality
Satellite reception may be interrupted due to one of the
following reasons.
•The vehicle is parked in an underground parking
structure or under a physical obstacle.
•Dense tree coverage may interrupt reception in the
form of short audio mutes.
•Driving under wide bridges or along tall buildings can
cause intermittent reception.
•Placing objects over or too close to the antenna can
cause signal blockage.
REMOTE SOUND SYSTEM CONTROLS — IF
EQUIPPED
The remote sound system controls are located on the rear
surface of the steering wheel. Reach behind the wheel to
access the switches.
