the bottom of the remote control.
2. Replace the two AA batteries in the compartment.
Make sure that they are installed correctly.
3. Close the battery door securely.
Notice:Do not store the remote control in heat or
direct sunlight. This could damage the remote
control and it would not be covered by your vehicles
warranty. Keep the remote control stored in a cool,
dry place.
If the remote control is to be stored for a long period of
time, remove the batteries and keep them in a cool,
dry place.
Headphones
The RSE system includes two sets of wireless infrared
headphones.
Each set of headphones has an ON/OFF control. An
indicator light will illuminate on the headphones when
they are on. If the light does not illuminate, the batteries
may need to be replaced. See ªBattery Replacementº
later in this section for more information. To turn the
headphones OFF activate the ON/OFF control.
Each set of headphones has a volume knob. To adjust
the volume, adjust this knob.
The headphones will automatically turn off if they lose the
infrared signal from the system after approximately four
minutes in order to preserve their battery power. The
signal may be lost if the system is turned off or if the
headphones are out of range of the infrared signal
transmitters that are located below the video display
screen.
Battery Replacement
To change the batteries, do the following:
1. Loosen the screw on the battery compartment door
located on the left side of the headphone earpiece.
2. Replace the two AAA batteries in the compartment.

·Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags, rags,
¯oor mats ± anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You can not see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.

Auxiliary Battery
The auxiliary battery provision can be used to supply
electrical power to additional equipment that you
may choose to add, such as a slide-in camper.
If your vehicle has this
provision, this relay will be
located on the passenger's
side of the vehicle, next
to the auxiliary battery.When using this provision, connection should only be
made to the upper stud (A) of the relay. Do not
make connections to the lower stud (B) of the relay.
The auxiliary battery circuit is protected by a megafuse
located behind the auxiliary battery.
Be sure to follow the proper installation instructions that
are included with any electrical equipment that you
install.
Notice:When using the auxiliary battery provision,
the electrical load must not exceed 30 amps.
Always turn off any electrical equipment when not
in use. Leaving electrical equipment on for extended
periods will drain your battery.
Power Winches
If you wish to use a power winch on your vehicle, only
use it when your vehicle is stationary or anchored.
