Section 3 Instrument Panel
201

When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or 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 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 267.
Battery Run-Down Protection
This feature shuts off the dome lamps if they
are left on for more than 10 minutes when
the ignition is in LOCK. This will help prevent
the battery from running down.
221

If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together,
it means that something may be wrong
with the airbag system. If this ever
happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger seat
may not have the protection of the frontal
airbag. SeeAirbag Readiness Light
on page 242.
Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, but the engine is
not running, as a check
to show you it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving, you
may have a problem with the charging system.
It could indicate that you have problems with the
generator, the generator drive belt, or another
electrical problem. Have it checked right away.
Driving while this light is on could drain your battery.
When this light comes on, the Driver Information
Center (DIC) will also display the SERVICE
BATTERY NOT CHARGING SYSTEM message.
SeeDIC Warnings and Messages on page 267
for more information.
If you must drive a short distance with the light
on, be certain to turn off all your accessories,
such as the radio and air conditioner, to reduce
the drain on your battery.
245

Voltmeter Gage
When your engine
is not running, but the
ignition is in RUN,
this gage shows your
battery’s state of
charge in DC volts.
When the engine is running, the gage shows the
condition of the charging system. The charging
system regulates voltage based on the state of
the battery for improved fuel economy and battery
life. The gage may transition from a higher to
lower or a lower to higher reading, this is normal.
Readings between the low and high warning
zones indicate the normal operating range.Readings in the low warning zone may occur
when a large number of electrical accessories are
operating in the vehicle and the engine is left at
an idle for an extended period. This condition
is normal since the charging system is not able
to provide full power at engine idle. As engine
speeds are increased, this condition should
correct itself as higher engine speeds allow the
charging system to create full power. If there is
a problem with the battery charging system,
this light will come on or the SERVICE BATTERY
CHARGING SYSTEM DIC message will display.
SeeDIC Warnings and Messages on page 267
andCharging System Light on page 245for more
information.
Brake System Warning Light
With the ignition on, the brake system warning
light will come on when you set the parking brake.
If you try to drive with the parking brake engaged,
a chime will sound when the vehicle speed is
greater than 3 mph (5 km/h).
246

SERVICE BATTERY CHARGING
SYSTEM
On some vehicles, this message displays if there
is a problem with the battery charging system.
Under certain conditions, the charging system
light may also turn on in the instrument panel
cluster. SeeCharging System Light on page 245.
Driving with this problem could drain the battery.
Turn off all unnecessary accessories. Have
the electrical system checked as soon
as possible. See your dealer.
SERVICE BRAKE SYSTEM
This message displays along with the brake
system warning light if there is a problem with
the brake system. SeeBrake System Warning
Light on page 246. If this message appears, stop
as soon as possible and turn off the vehicle.
Restart the vehicle and check for the message
on the DIC display. If the message is still displayed
or appears again when you begin driving, the
brake system needs service as soon as possible.
See your dealer.
SERVICE BRAKES SOON
This message displays if there is a problem with
the brake system. If this message appears, stop
as soon as possible and turn off the vehicle.
Restart the vehicle and check for the message on
the DIC display. If the message is still displayed
or appears again when you begin driving, the
brake system needs service. See your dealer.
SERVICE PARK ASSIST
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system, this message displays
if there is a problem with the URPA system.
Do not use this system to help you park.
SeeUltrasonic Rear Parking Assist (URPA)
on page 222for more information. See your
dealer for service.

Trailer Wiring Harness
Heavy-Duty Trailer Wiring Package
Your vehicle is equipped with the seven-wire
trailer towing harness. This harness with a
seven-pin universal heavy-duty trailer connector
is attached to the rear bumper beam. It is located
next to the integrated trailer hitch.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 #
** If you are charging a remote (non-vehicle)
battery, press the tow/haul mode button 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, you can turn on the headlamps as a
second way to boost the vehicle system and
charge the battery.
# The fuses for these circuits are installed in the
underhood electrical center, but the wires are
not connected. These circuits should be connected
by your dealer or a qualied service technician.
