fuse Ram 4500 Chassis Cab 2019 Owner's Manual

INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this
vehicle’s electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained person-
nel. The following must be observed during installation.
The positive power connection should be made directly
to the battery and fused as close to the battery as possible.
The negative power connection should be made to body
sheet metal adjacent to the negative battery connection.
This connection should not be fused.
Antennas for two-way radios should be mounted on the
roof or the rear area of the vehicle. Care should be used
in mounting antennas with magnet bases. Magnets may
affect the accuracy or operation of the compass on
vehicles so equipped.
The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use
only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to
ensure a low Standing Wave Ratio (SWR).Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible interfer-
ence between the communications equipment and the
vehicle’s electronic systems.
WARNING:
Operating, servicing and maintaining a
passenger vehicle or off-road highway
motor vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to
the State of California to cause cancer and
birth defects or other reproductive harm.
To minimize exposure, avoid breathing
exhaust, do not idle the engine except as
necessary, service your vehicle in a
well-ventilated area and wear gloves or
wash your hands frequently when servicing
your vehicle. For more information go to
www.P65Warnings.ca.gov/passenger-vehicle.

DRIVING AND ALCOHOL
Drunken driving is one of the most frequent causes of
accidents.
Your driving ability can be seriously impaired with blood
alcohol levels far below the legal minimum. If you are
drinking, don’t drive. Ride with a designated non-
drinking driver, call a cab, a friend, or use public trans-
portation.
WARNING!
Driving after drinking can lead to an accident.
Your perceptions are less sharp, your reflexes are
slower, and your judgment is impaired when you
have been drinking. Never drink and then drive.
This manual illustrates and describes the operation of
features and equipment that are either standard or op-
tional on this vehicle. This manual may also include a
description of features and equipment that are no longer
available or were not ordered on this vehicle. Please
disregard any features and equipment described in this
manual that are not on this vehicle.
FCA US LLC reserves the right to make changes in design
and specifications, and/or make additions to or improve-
ments to its products without imposing any obligation

Some vehicles may be equipped with a rear cupholder that
consists of two cup wells for rear passenger convenience.Rear Cup Wells
Electrical Power Outlets

The auxiliary 12 Volt (13 Amp) power outlet can provide
power for in-cab accessories designed for use with the stan -
dard “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 key 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.2

118 GETTING TO KNOW YOUR VEHICLE
An auxiliary power outlet can be found in the tray on top of
the center stack. This power outlet only works when the
vehicle is in the ON/RUN or ACC position.Power Outlet — Top Of Center Stack
Power Outlet Fuse Locations:
• F104 Fuse 20 A Yellow UCI Port/ USB Rear Center Console
• F90Fuse 20 A Yellow Instrument Panel Power Outlet Battery Fed (If Equipped) • F91 Fuse 20 A Yellow Instrument Panel Power Outlet Igni
-
tion Fed (If Equipped)
• F93 Fuse 20 A Yellow Cigar Lighter/ Instrument Panel Power Outlet (If Equipped)
When the vehicle is turned off, be sure to unplug any equip -
ment as to not drain the battery of the vehicle. All accessories
connected to the outlet(s) should be removed or turned off
when the vehicle is not in use to protect the battery against
discharge.
WARNING!
To avoid serious injury or death:
• Only devices designed for use in this type of outlet should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving the vehicle.
• If this outlet is mishandled, it may cause an electric shock and failure.

3. Pull the bulb straight from it's socket and replace.Removing The Bulb From The Bulb SocketFUSES
WARNING!
• When replacing a blown fuse, always use an appro -
priate replacement fuse with the same amp rating as the
original fuse. Never replace a fuse with another fuse of
higher amp rating. Never replace a blown fuse with
metal wires or any other material. Do not place a fuse
inside a circuit breaker cavity or vice versa. Failure to
use proper fuses may result in serious personal injury,
fire and/or property damage.
• Before replacing a fuse, make sure that the ignition is off and that all the other services are switched off and/
or disengaged.
• If the replaced fuse blows again, contact an authorized dealer.
• If a general protection fuse for safety systems (air bag system, braking system), power unit systems (engine
system, transmission system) or steering system blows,
contact an authorized dealer.
