A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at high
speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable
to the driver. If so, a Driver Information Center (DIC)
message might be displayed, such as Battery Saver
Active or Service Battery Charging System. If this
message is displayed, it is recommended that the
driver reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 3-59.
Battery Run-Down Protection
This feature shuts off the dome, and reading lamps
if they are left on for more than 10 minutes when
the ignition is off. This will keep the battery from
running down.
Accessory Power Outlet(s)
Accessory power outlets can be used to connect
auxiliary electrical equipment, such as a cellular
telephone or CB radio.
There are two under the climate controls, one inside
the center oor console, one on the rear of the center
oor console and one accessory power outlet in the
rear cargo area on the passenger side.
To use an accessory power outlet, remove the protective
cap. When not in use, always cover the accessory
power outlet with the protective cap.
The accessory power outlets are powered, even with
the ignition off. Continuing to use accessory power
outlets while the ignition is in LOCK/OFF may cause
the vehicle’s battery to run down.
Notice:If electrical devices are left plugged into
a power outlet, the battery may drain causing
your vehicle not to start or damage to the battery.
This would not be covered by the warranty.
Always unplug all electrical devices when turning
off your vehicle.

Using the Auxiliary Input Jack
The radio system has an auxiliary input jack located on
the lower right side of the faceplate. This is not an
audio output; do not plug the headphone set into the
front auxiliary input jack. An external audio device such
as an iPod, laptop computer, MP3 player, CD player,
or cassette tape player, etc. can be connected to
the auxiliary input jack for use as another audio source.
Drivers are encouraged to set up any auxiliary device
while the vehicle is in PARK (P). SeeDefensive Driving
on page 4-2for more information on driver distraction.
To use a portable audio player, connect a 3.5 mm
(1/8 inch) cable to the radio’s front auxiliary input jack.
When a device is connected, press the radio CD/AUX
button to begin playing audio from the device over
the vehicle speakers.
For optimal sound quality, increase the portable audio
device’s volume to the loudest level.
It is always best to power the portable audio device
through its own battery while playing.
O(Power/Volume):Turn clockwise or
counterclockwise to increase or decrease the
volume of the portable player. Additional volume
adjustments might have to be made from the portable
device if the volume is not loud or soft enough.BAND:Press to listen to the radio when a portable
audio device is playing. The portable audio device also
continues to play.
CD/AUX (CD/Auxiliary):Press to play a CD when a
portable audio device is playing. Press again and
the system begins playing audio from the connected
portable audio player. If a portable audio player is
not connected, “No Input Device Found” displays.
DVD/CD AUX (CD/Auxiliary):Press this button to cycle
through DVD, CD, or Auxiliary when listening to the
radio. The DVD/CD text label and a message showing
track or chapter number displays when a disc is in
either slot. Press this button again and the system
automatically searches for an auxiliary input device,
such as a portable audio player. If a portable audio
player is not connected, “No Aux Input Device” displays.
If a disc is in both the DVD slot and the CD slot the
DVD/CD AUX button cycles between the two sources
and does not indicate “No Aux Input Device”. If a
front auxiliary device is connected, the DVD/CD AUX
button cycles through all available options, such
as: DVD slot, CD slot, Front Auxiliary, and Rear Auxiliary
(if available). See “Using the Auxiliary Input Jack(s)”
later in this section, or “Audio/Video (A/V) Jacks” under,
Rear Seat Entertainment (RSE) System on page 3-105
for more information.

subtitles and to move through subtitle options when a
DVD is playing. The format and content of this function
vary for each disc.
AUX (Auxiliary):Press this button to switch the system
between the DVD player and an auxiliary source.
d(Camera):Press this button to change camera
angles on DVDs that have this feature when a DVD is
playing. The format and content of this function vary
for each disc.

provides the capability of direct chapter or track
number selection.
\(Clear):Press this button within three seconds after
entering a numeric selection, to clear all numerical
inputs.

select chapter or track numbers greater than nine.
Press this button before entering the number.
If the remote control becomes lost or damaged, a new
universal remote control can be purchased. If this
happens, make sure the universal remote control uses a
code set of Toshiba
®.
Battery Replacement
To change the remote control batteries, do the following:
1. Slide the rear cover back on to the remote control.
2. Replace the two batteries in the compartment.
Make sure that they are installed correctly, using
the diagram on the inside of the battery
compartment.
3. Replace the battery cover.
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.
