Infotainment System 7-39
The RSE includes two 2-channel
wireless headphones that are
dedicated to this system. Channel 1
is dedicated to the video screen,
while Channel 2 is dedicated to
Rear Seat Audio (RSA) selections.
These headphones can be used to
listen to the radio, CDs, DVDs,
MP3s, DVD-As, or any auxiliary
source connected to A/V jacks or
the auxiliary input jack, if the vehicle
has this feature. The wireless
headphones have a power button,
channel 1 or 2 switch, and a volume
control.
Push the power button to turn on
the headphones. An indicator light
located on the headphones comes
on. If the light comes on, but there
is intermittent sound and/or static on
the headphones, or if the indicator
light does not come on, the batteries
might need to be replaced. See
“Battery Replacement”later in this
section for more information. Switch
the headphones to Off when not
in use. Infrared transmitters are located at
the rear of the overhead console.
The headphones shut off
automatically to save the battery
power if the RSE system and RSA
are shut off, or if the headphones
are out of range of the transmitters
for more than three minutes. If you
move too far forward or step out of
the vehicle, the headphones lose
the audio signal.
To adjust the volume on the
headphones, use the volume control
located on the right side.
For optimal audio performance, the
headphones must be worn correctly.
Headphones should be worn with
the headband over the top of the
head for best audio reception. The
symbol L (Left) appears on the
outside bottom edge of the ear cup
and should be positioned on the left
ear. The symbol R (Right) appears
on the outside bottom edge of the
ear cup and should be positioned on
the right ear.

headphones in heat or direct
sunlight. This could damage the
headphones and repairs will not
be covered by the warranty.
Storage in extreme cold can
weaken the batteries. Keep the
headphones stored in a cool, dry
place.
If the foam ear pads attached to the
headphones become worn or
damaged, the pads can be replaced
separately from the headphone set.

The A/V jacks are color coded to
match typical home entertainment
system equipment.
The A/V jacks, located on the rear
of the floor console, allow audio or
video signals to be connected from
an auxiliary device such as a
camcorder or a video game unit to
the RSE system. Adapter
connectors or cables (not included)
may be required to connect the
auxiliary device to the A/V jacks.

Driving and Operating 9-91
Fifth-wheel or gooseneck kingpin
weight should be 15 to 25 percent of
the trailer weight up to the maximum
amount specified in the trailering
chart for the vehicle. See“Weight of
the Trailer” underTrailer Towing on
page 9‑73 for more information.
The hitch should be located in the
pickup bed so that its centerline is
over or slightly in front of the rear
axle. Take care that it is not so far
forward that it will contact the back
of the cab in sharp turns. This is
especially important for short box
pickups. Trailer pin box extensions
and sliding fifth-wheel hitch
assemblies can help this condition.
There should be at least six inches
of clearance between the top of the
pickup box and the bottom of the
trailer shelf that extends over
the box.
Make sure the hitch is attached to
the tow vehicle frame rails. Do not
use the pickup box for support.Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Instructions about safety chains
may be provided by the hitch
manufacturer or by the trailer
manufacturer. If the trailer being
towed weighs up to 2 271 kg
(5,000 lbs) with a factory-installed
step bumper, safety chains may be
attached to the attaching points on
the bumper; otherwise, safety
chains should be attached to holes
on the trailer hitch platform. Always
leave just enough slack so the
combination can turn. Never allow
safety chains to drag on the ground.
Trailer Brakes
A loaded trailer that weighs more
than 900 kg (2,000 lbs) needs to
have its own brake system that is
adequate for the weight of the
trailer. Be sure to read and follow the instructions for the trailer brakes
so they are installed, adjusted, and
maintained properly.
Do not tap into the vehicle's
hydraulic brake system.
Auxiliary Battery
The auxiliary battery provision can
be used to supply electrical power
to additional equipment that may be
added, such as a slide-in camper.
If the vehicle has this provision, this
relay will be located on the driver
side of the vehicle, next to the
underhood electrical center.
Be sure to follow the proper
installation instructions included with
any electrical equipment that is
installed.
Notice:
Leaving electrical
equipment on for extended
periods will drain the battery.
Always turn off electrical
equipment when not in use and
do not use equipment that

exceeds the maximum amperage
rating of 40 amperes for the
auxiliary battery provision.
Trailer Wiring Harness
The vehicle is equipped with one of
the following wiring harnesses for
towing a trailer or hauling a slide-in
camper.
Basic Trailer Wiring
All regular, extended cab and crew
cab pickups have a seven-wire
trailer towing harness.
For vehicles not equipped with
heavy duty trailering, the harness is
secured to the vehicle's frame
behind the spare tire mount. The
harness requires the installation of a
trailer connector, which is available
through your dealer.
If towing a light-duty trailer with a
standard four-way round pin
connector, an adapter is available
from your dealer.Heavy-DutyTrailer Wiring Harness
Package
For vehicles equipped with heavy
duty trailering, the harness
connector is mounted in the bumper.
The seven-wire harness contains
the following trailer circuits:
.Yellow: Left Stop/Turn Signal
.Dark Green: Right Stop/Turn
Signal
.Brown: Taillamps
.White: Ground
.Light Green: Back-up Lamps
.Red: Battery Feed*
.Dark Blue: Trailer Brake*
*The fuses for these two circuits are
installed in the underhood electrical
center, but the wires are not
connected. They should be
connected by your dealer or a
qualified service center. The fuse
and wire for the ITBC is factory
installed and connected if the
vehicle is equipped with an ITBC.
The fuse for the battery feed is not
required if the vehicle has an
auxiliary battery. If the vehicle does
not have an auxiliary battery, have
your dealer or authorized service
center install the required fuse.
If charging a remote (non-vehicle)
battery, press the Tow/Haul Mode
button, if equipped, located at the
end of the shift lever. This will boost
the vehicle system voltage and
properly charge the battery. If the
trailer is too light for Tow/Haul
Mode, or the vehicle is not equipped
with Tow/Haul, turn on the
