Activated automatically when low beams
come on. This is the normal low beam light
pattern.

side of the road is improved, reducing glare
to oncoming and preceding vehicles.
The high beams may not turn off
automatically if the system cannot detect
another vehicle's lamps because of any of
the following:
.The other vehicle's lamps are missing,
damaged, obstructed from view,
or otherwise undetected.
.The other vehicle's lamps are covered
with dirt, snow, and/or road spray.
.The other vehicle's lamps cannot be
detected due to dense exhaust, smoke,
fog, snow, road spray, mist, or other
airborne obstructions.
.The vehicle's windshield is dirty, cracked,
or obstructed by something that blocks
the view of the light sensor.
.The vehicle is loaded such that the front
end points upward, causing the light
sensor to aim high and not detect
headlamps and taillamps.
.Driving on winding or hilly roads.The automatic high-beam headlamps may
need to be disabled if any of the above
conditions exist.

The exit lighting for exterior lights can be

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.
Battery Power Protection
The battery saver feature is designed to
protect the vehicle's battery.
If some interior lamps are left on and the
ignition is turned off, the battery rundown
protection system automatically turns the
lamp off after some time.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes
after the ignition is turned off, if the parking
lamps or headlamps have been manually
left on. This protects against draining the
battery. To restart the 10-minute timer, turn
the exterior lamp control to the
Oposition
and then back to the
;or2position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.
