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.
.The vehicle is being driven
on winding or hilly roads.

headlamps may need to be
disabled if any of the above
conditions exist.

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 thestate of charge is high, the
voltage is lowered slightly to
prevent overcharging. If the
vehicle has a voltmeter gauge
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, 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. If a battery
message is displayed, it is
recommended that the driver
reduce the electrical loads as
much as possible. See Driver
Information Center (DIC) (Base
Level)
0129 or
Driver Information Center
(DIC) (Uplevel) 0132.

with a soft cloth
dampened with a mild
soap and water solution.
Interior Glass
To clean, use a microfiber
cloth fabric dampened with
water. Wipe droplets left
behind with a clean dry cloth.
If necessary, use a commercial
glass cleaner after cleaning
with plain water.
Caution
To prevent scratching, never
use abrasive cleaners on
automotive glass. Abrasive
cleaners or aggressive
cleaning may damage the
rear window defogger.
Cleaning the windshield with
water during the first three to
six months of ownership will
reduce tendency to fog.
Speaker Covers
Vacuum around a speaker
cover gently, so that the
speaker will not be damaged.
Clean spots with water and
mild soap.
Coated Moldings
Coated moldings should be
cleaned.
.When lightly soiled, wipe
with a sponge or soft,
lint-free cloth dampened
with water.
.When heavily soiled, use
warm soapy water.
Vinyl/Rubber
If equipped with vinyl floor and
rubber floor mats, use a soft
cloth and/or brush dampened
with water to remove dust and
loose dirt. For more thorough
cleaning, use a mild soap and
water solution.
{Warning
Do not use cleaners that
contain silicone, wax-based
products, or cleaners that
increase gloss on vinyl/
rubber floor and mats.
These cleaners can
permanently change the
appearance and feel of the
vinyl/rubber and can make
the floor slippery. Your foot
could slip while operating
the vehicle, and you could
lose control, resulting in a
crash. You or others could
be injured.
Fabric/Carpet/Suede
Start by vacuuming the
surface using a soft brush
attachment. If a rotating
vacuum brush attachment is
being used, only use it on the
floor carpet. Before cleaning,
gently remove as much of the
soil as possible:
