radio RAM CHASSIS CAB 2012 Repair Manual

Preparations For Jump-Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE: The positive battery post is covered with a
protective cap. Lift up on the cap to gain access to the
positive battery post. WARNING!• Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is on. You can be injured by
moving fan blades.
• Remove any metal jewelry such as watch bands or
bracelets that might make an inadvertent electrical
contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift the automatic transmission
into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories.Positive Battery Post
6 WHAT TO DO IN EMERGENCIES 389

Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with MOPAR  Glass Cleaner or any commercial
household-type glass cleaner. Never use an abrasive type
cleaner. Use caution when cleaning the inside rear win-
dow equipped with electric defrosters or the right rear
quarter window equipped with the radio antenna. Do
not use scrapers or other sharp instruments which may
scratch the elements. When cleaning the rearview mirror,
spray cleaner on the towel or rag that you are using. Do
not spray cleaner directly on the mirror.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet soft rag. A mild soap solution may be
used, but do not use high alcohol content or abrasive
cleaners. If soap is used, wipe clean with a clean damp rag. 2. Dry with a soft cloth.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the car to
wash them. Dry with a soft cloth.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
FUSES
Totally Integrated Power Module
The Totally Integrated Power Module is located in the
engine compartment near the battery. This center con-
tains cartridge fuses and mini fuses. A description of each
fuse and component may be stamped on the inside cover,

CAUTION! (Continued)• When replacing a blown fuse, it is important to
use only a fuse having the correct amperage rating.
The use of a fuse with a rating other than indicated
may result in a dangerous electrical system over-
load. If a properly rated fuse continues to blow, it
indicates a problem in the circuit that must be
corrected.
VEHICLE STORAGE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to mini-
mize the drain on your vehicle’s battery:
• Disconnect the Ignition-Off Draw (IOD) fuse located in
the Integrated Power Module, located in the engine
compartment. The IOD cavity includes a snap-in re-
tainer that allows the fuse to be disconnected without
removing it from the fuse block. • As an alternative to the above steps you may discon-
nect the negative cables from both batteries.
• Any time you store your vehicle or keep it out of
service (i.e., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
NOTE:
• When reinstalling the IOD fuse push firmly until fully
seated; the gauges in the instrument cluster will do a
full sweep when the ignition switch is turned to the
RUN position. This is a normal condition.
• When the vehicle is shipped from the factory, the IOD
fuse is in the up or extracted position. If the radio,
interior lamps, keyless entry or other features do not
work with the key OFF, check the position of the fuse

INSTALLATION OF RADIO TRA
NSMITTING
EQUIPMENT
Special design considerations are incorporated into this vehi-
cle’s electronic system to provide immunity to radio frequency
signals. Mobile two-way radios and telephone equipment must
be installed properly by trained personnel. 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 con-
nection 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 accu-
racy 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 nor-
mal may require special precautions.
All installations should be checked for possible interference
between the communications equipment and the vehicle’s
electronic systems.
