Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly bring the charge back up. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up or down.
This is normal. If there is a problem, an alert will be
displayed.
The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be spinning
fast enough at idle to produce all the power that is
needed for very high electrical loads.
A high electrical load occurs when several of the
following are on, such as: 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 increaseengine 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,
BATTERY VOLTAGE LOW, or LOW BATTERY. 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 3-64.
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.
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.

DVD Radio Error Messages
Player Error:This message displays when there are
disc load or eject problems.
Disc Format Error:This message displays, if the disc
is inserted with the disc label wrong side up, or if
the disc is damaged.
Disc Region Error:This message displays, if the disc
is not from a correct region.
No Disc Inserted:This message displays, if no disc is
present when the
Zor DVD/CD AUX button is pressed
on the radio.
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 P (Park). 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.

Headphones
The RSE includes two 2-channel wireless headphones
that are dedicated to this system. Channel 1 is dedicated
to the DVD player, while Channel 2 is dedicated to RSA
selections. These headphones are used to listen to
media such as CDs, DVDs, MP3s, DVDAs, radio, any
auxiliary source connected to A/V jacks, or the auxiliary
input jack, if the vehicle has this feature. The wireless
headphones have an On/Off button, channel 1/2 switch,
and a volume control.If the vehicle has a third row video screen display, it
may have two additional headphones.
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
RSE 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.
The headphones automatically turn off after four hours
of continuous use.

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.1 through 0 (Numeric Keypad):The numeric keypad
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.
}10 (Double Digit Entries):Press this button to
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:
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.
