of cupholders and console storage.Rear Armrest Cupholder With Smart FoldElectrical Power Outlets
The auxiliary 12 Volt (13 Amp) power outlet can provide
power for in-cab accessories designed for use with the
standard “cigar lighter” plug. The 12 Volt power outlets
and 5 Volt (2.5 Amp) USB Port (Charge Only) have a cap
attached to the outlet indicating “12V DC,” together with
either a key symbol, battery symbol, or USB symbol.
A key symbol indicates that the ignition must be in the ON/
RUN or ACC positions for the outlet to provide power. The
battery symbol indicates that the outlet is connected to the
battery, and can provide power at all times.
CAUTION!

• Do not exceed the maximum power of 160 Watts (13 Amps) at 12 Volts. If the 160 Watts (13 Amps) power rating is
exceeded, the fuse protecting the system will need to be
replaced.

• Power outlets are designed for accessory plugs only. Do not insert any other object in the power outlets as this
will damage the outlet and blow the fuse. Improper use
of the power outlet can cause damage not covered by
your New Vehicle Limited Warranty.

NOTE:
If you are installing a Toolbox, Ladder Rack or Headache
Rack at the front of the Pickup Box, you must use Mopar Box
Reinforcement Brackets that are available from an autho-
rized dealer.
You can carry wide building materials (sheets of plywood,
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.
There are stampings in the sheet metal on the inner side
bulkheads of the box in front of and behind both wheel hous-
ings. 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.

RAMBOX — IF EQUIPPED
The RamBox system is an integrated pickup box storage and
cargo management system consisting of three features:
• Integrated box side storage bins
• Cargo divider
• Bed rail tie-down system
WARNING!
• The pickup box is intended for load carrying purposes only, not for passengers, who should sit in seats and
use seat belts.
• 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 materialsuspended above the wheelhouse, supports 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 acci -
dent causing serious or fatal injury.

Base / Midline Instrument Cluster Descriptions
1. Tachometer• Indicates the engine speed in revolutions per minute(RPM x 1000).
2. Voltmeter
• When the vehicle is in the RUN state, the gauge indi -
cates the electrical system voltage. The pointer should
stay within the normal range if the battery is charged.
If the pointer moves to either extreme left or right and
remains there during normal driving, the electrical
system should be serviced.
NOTE:
In vehicles equipped with Stop/Start, a reduced voltage may
be present during an Autostop.
3. Instrument Cluster Display
• When the appropriate conditions exist, this displayshows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information. 4. Oil Pressure Gauge
• The pointer should always indicate the oil pressurewhen the engine is running. A continuous high or low
reading under normal driving conditions may indicate
a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
NOTE:
In vehicles equipped with Stop/Start, an oil pressure indica -
tion of zero is normal during an Autostop.
5. Speedometer
