them. If the blades do become
worn or damaged, get new blades
or blade inserts.
Windshield wipers work in all power
modes, except when the ignition
is set to LOCK/OFF. After the
engine is turned off, wipers will work
in Retained Accessory Power
(RAP) mode until a door is opened.

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 bring the charge
back up. When the state of charge is
high, the voltage is lowered
slightly to prevent overcharging. If
the vehicle has a voltmeter gage 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 fastenough 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 Driver Information
Center (DIC) message might be
displayed, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
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 3-37.
Battery Run-Down
Protection
This feature shuts off the dome
lamp if it is left on for more
than 20 minutes when the ignition is
in LOCK/OFF. This helps to
prevent the battery from being
drained.
Instrument Panel 3-17

[(Floor):Air is directed to the
oor outlets, side window outlets,
and defroster. Recirculation is
not available in this mode.
/(Floor/Defog):This mode clears
the windows of fog and moisture.
Air is directed to the windshield, side
window, and oor outlets. The
system runs the air conditioning
unless the outside temperature is
near freezing or below. Recirculation
is not available in this mode.
0(Defrost):This mode clears
the windshield of fog or frost
more quickly. Air is directed to the
windshield and side window
outlets. The system runs the air
conditioning system unless
the outside temperature is near or
below freezing. Recirculation is
not available in this mode.
Do not drive the vehicle until all the
windows are clear.
#(Air Conditioning):Press to
turn the air conditioning system on
or off. An indicator light comes
on when the air conditioning
is turned on. This system cools and
dehumidies the air entering the
vehicle.
The air conditioning will not function
if the fan is turned off. If air
conditioning is selected with fan off,
the indicator light ashes three
times and then turns off.
A slight change in engine
performance may occur when the
air conditioning compressor shuts off
and turns on again. This is normal.
The system is designed to make
adjustments to help with fuel
economy while still maintaining the
selected temperature.
The air conditioning system removes
moisture from the air, so a small
amount of water might drip
under the vehicle while idling or
after turning off the engine. This is
normal.@(Recirculation):Press to turn
the recirculation mode on or off. An
indicator light comes on when the
recirculation is on. This mode
recirculates and helps to quickly cool
the air inside the vehicle. It can be
used to prevent outside air and odors
from entering the vehicle.
Recirculation is available in the
bi-level and vent modes. This mode
cannot be selected while in the oor,
oor/defog or defrost modes. If you
try to select the recirculation mode,
the indicator ashes three times
indicating it is not available in that
mode. When the recirculation mode
is turned on, the air conditioning
turns on automatically.
When it is hot enough outside, the
recirculation mode may turn on
automatically to help improve cooling
performance. The indicator light will
be lit to show this mode is active. If
the recirculation button is pressed
while in this mode, the light ashes
three times and stays on to indicate
that recirculation may not be shut off.

Warning Lights,
Gages, and Indicators
Warning lights and gages can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gages could
prevent injury.
Warning lights come on when there
may be or is a problem with one
of the vehicle’s functions. Some
warning lights come on briey when
the engine is started to indicate
they are working.
Gages can indicate when there may
be or is a problem with one of the
vehicle’s functions. Often gages and
warning lights work together to
indicate a problem with the vehicle.When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains what
to do. Follow this manual’s advice.
Waiting to do repairs can be
costly and even dangerous.
