Lighting Features
Entry Lighting
Some exterior lamps and the interior lamps
turn on briefly at night, or in areas with
limited lighting, when
Kis pressed on the
Remote Keyless Entry (RKE) transmitter.
When a door is opened, the interior lamps
come on if the dome lamp control is in the
DOOR position. After about 30 seconds the
exterior lamps turn off. Entry lighting can be
disabled manually by changing the ignition
out of the OFF position, or by pressing the
RKE transmitter
Qbutton.
This feature can be changed. See “Vehicle
Locator Lights” underVehicle Personalization
0 99.
Exit Lighting
Some exterior lamps and interior lamps turn
on when the key is removed from the
ignition.
The exterior and interior lamps remain on
for a set amount of time, then automatically
turn off. If equipped with Keyless Access,
the exterior lamps automatically turn on
when the driver door is opened after the
ignition is turned off. The interior lights turn on when the ignition
is turned off.
The exterior lamps turn off immediately by
turning the exterior lamp control off.
This feature can be changed. See
Vehicle
Personalization 099.
Battery Load Management
The vehicle has Electric Power Management
(EPM), which 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. The
voltmeter gauge or the voltage display on
the Driver Information Center (DIC),
if equipped, may show the voltage moving
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 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 DIC message might be
displayed and it is recommended that the
driver reduce the electrical loads as much as
possible.
