Lighting 6-9
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 one of these messages displays,
it is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) on page 5‑18.Battery Power Protection
The dome lamp is shut off 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.

Introduction
Determine which radio the vehicle
has and read the following pages to
become familiar with its features.
{WARNING
Taking your eyes off the road
for extended periods could
cause a crash resulting in injury
or death to you or others. Do not
give extended attention to
entertainment tasks while driving.
This system provides access to
many audio and non‐audio listings.
To minimize taking your eyes off the
road while driving, do the following
while the vehicle is parked:
.Become familiar with the
operation and controls of the
audio system.
.Set up the tone, speaker
adjustments, and preset radio
stations. For more information, see
Defensive
Driving on page 9‑2.
Notice: Contact your dealer
before adding any equipment.
Adding audio or communication
equipment could interfere with
the operation of the vehicle's
engine, radio, or other systems,
and could damage them. Follow
federal rules covering mobile
radio and telephone equipment.
The vehicle has Retained
Accessory Power (RAP). With RAP,
the audio system can be played
even after the ignition is turned off.
See Retained Accessory Power
(RAP)
on page 9‑35for more
information.
For vehicles with a navigation radio
system, see the separate Navigation
System manual.

8-2 Climate Controls
9(Fan Control): Turn clockwise or
counterclockwise to increase or
decrease the fan speed.
Air Delivery Mode Control: Turn
clockwise or counterclockwise to
change the direction of the airflow in
the vehicle. The airflow can be set
between modes.
To change the current mode, select
one of the following:
H (Vent): Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is directed to the
instrument panel outlets, and the
remaining air to the floor outlets
and the defroster and side window
outlets. Cooler air is directed to the
upper outlets and warmer air to the
floor outlets. [
(Floor): Air is directed to the
floor outlets, side window outlets,
and defroster. Recirculation is not
available in this mode.
/ (Floor/Defog): This clears the
windows of fog and moisture. Air is
directed to the windshield, side
window, and floor 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 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
dehumidifies 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 flashes
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
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
