Delayed Exit Lighting
This feature illuminates the interior for a period of
time after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to
work. When the key is removed, interior illumination
will activate and remain on until one of the following
occurs:
The ignition is in ON.
The power door locks are activated.
An illumination period of 20 seconds has
elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled
and the interior lamps will remain on because a
door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. It automatically prohibits the
dimming of the instrument panel displays during
the daylight while the headlamps are on so
that you will still be able to see the displays.
Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on
and off.
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 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 199.
Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained, if the interior courtesy
lamps, reading/map lamps, visor vanity lamps
or trunk lamp are accidentally left on. If any
of these lamps are left on, they will automatically
turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until
one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then
on again.
The headlamps will timeout after 10 minutes, if they
are manually turned on before the ignition is off.

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 a
generator drive belt, or another electrical problem.
Have it checked right away. Driving while this
light is on could drain your battery.
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.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good braking,
though, you need both parts working well.
If the warning light comes on, there is a brake
problem. Have your brake system inspected
right away.
This light should come on briey when you turn
the ignition key to RUN. If it does not come
on then, have it xed so it will be ready to warn
you if there is a problem.

SERVICE BATTERY CHARGING
SYSTEM
This message displays when there is a problem
with the generator and battery charging systems.
Driving with this problem could drain the battery.
Turn off all unnecessary accessories. Stop
and turn off the vehicle as soon as it is safe to do
so. Have the electrical system checked by your
dealer immediately.
SERVICE BRAKE SYSTEM
This message displays when service is required
on the brake system. Have the brake system
serviced by your dealer as soon as possible.
The brake system warning light also appears on
the instrument panel cluster when this message
appears on the DIC. SeeBrake System Warning
Light on page 181.
SERVICE POWER STEERING
This message displays when a problem is
detected with the power steering system. When
this message is displayed, you may notice that the
effort required to steer the vehicle increases or
feels heavier, but you will still be able to steer the
vehicle. Have your vehicle serviced by your
dealer immediately.
SERVICE THEFT SYSTEM
This message displays when there is a problem
with the theft-deterrent system programmed in the
key. A fault has been detected in the system
which means that the system is disabled and it is
not protecting the vehicle. The vehicle usually
restarts; however, you may want to take the
vehicle to your dealer before turning off the engine.
