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 of the
power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, 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 the exterior lamps or any interior
lamp is left on and the ignition is
turned off, the battery rundown
protection system automatically
turns the lamp off after about
10 minutes.

weather.
For ECO a/c, touch A/C again. This
setting balances fuel economy and
air conditioning comfort. In warm
weather conditions, auto stops may
occur more frequently, last longer,
and the vehicle interior may be
warmer during auto stops as
compared to the MAX A/C setting.
This setting allows higher humidity
inside the vehicle and window
fogging may occur before the
engine restarts.
@:Press to turn on recirculation.
An indicator light comes on. Air is
recirculated to quickly cool the
inside of the vehicle or to reduce the
entry of outside air and odors. If selected during cool or cold
weather, the windshield and
windows may fog. Turn off
recirculation to help clear the
windshield and windows.
If equipped, the Air Quality Sensor
may operate the recirculation mode
automatically. See
“Climate and Air
Quality” underVehicle
Personalization 0138.
Auto Defog : If equipped, the
climate control system may have a
sensor to automatically detect high
humidity inside the vehicle. When
high humidity is detected, the
climate control system may adjust to
outside air supply and turn on the
air conditioner. The fan speed may
slightly increase to help prevent
fogging. If the climate control
system does not detect possible
window fogging, it returns to normal
operation.
To turn Auto Defog off or on, see
“Climate and Air Quality” under
Vehicle Personalization 0138.

off when the ignition is placed in the
ACC/ACCESSORY or LOCK/OFF
position.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization 0138.
When Auto Rear Defog is selected,
the rear window defogger turns on
automatically when the interior
temperature is cold and the outside
temperature is about 4 °C (40 °F)
and below. The auto rear defogger
turns off automatically after about
10 minutes, or after five minutes if
the outside temperature is not
as cold.
The upper gridlines on the rear
window are antenna lines and are
not intended to heat when the
defogger is activated.
