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 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 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 4-41.
Battery Run-Down Protection
The battery run-down feature is designed to protect the
vehicle’s battery.
When any interior lamp (trunk, reading lamps, or dome
lamp) is left on when the ignition is turned off, the
battery run-down protection system automatically shuts
the lamp off after 20 minutes. This prevents draining
of the battery.
To reactivate the interior lamps, do one of the following:
•Open any door.
•Press any Remote Keyless Entry (RKE) transmitter
button.
•Press the power door lock switch.
•Press the remote trunk release.
•Turn the lamp that was left on to off and then to on
again.

Operation and Fuel Economy
The climate control system is dependent upon other
vehicle systems for heat and power input. Certain
climate control settings can lead to higher fuel usage
and/or fewer Auto Stops.
The following are climate control settings that use
more fuel:
•Normal air conditioning mode.
•The defrost mode.
•Extreme temperature settings, such as
60°F (15°C) / 90°F (32°C).
•High fan speed settings.
To help reduce fuel usage:
•Use the full automatic control as described under
Automatic Operation.
•Use hybrid air conditioning, instead of the normal
air conditioning.
•Select a temperature setting that is higher in hot
weather and lower in cold weather.
•Turn off the air conditioning when it is not needed.
•Only use defrost to clear the windows.
These suggestions will help to reduce fuel consumption,
but may reduce overall comfort.

Automatic Operation
AUTO (Automatic):Select AUTO on both the fan
speed knob and the air delivery mode knob to activate
the automatic system. When automatic operation is
active the system controls the inside temperature and
air delivery.
Use the steps below to place the entire system in full
automatic control:
1. Turn the fan knob and the mode knob to the AUTO
position.
The current set temperature displays. When AUTO
is selected, the air conditioning operation and air
inlet is automatically controlled. The air conditioning
compressor runs while the outside temperature is
over about 40°F (4°C). The air inlet is normally
set to outside air. If it is hot outside, the air inlet can
automatically switch to recirculate inside air to
help quickly cool down the vehicle.2. Set the temperature.
An initial setting of 73°F (23°C) is recommended.
Allow about 20 minutes for the system to regulate.
Press the
worxarrow temperature buttons
to adjust the temperature setting as necessary. If
the temperature is set at 60°F (15°C) the system
remains at the maximum cooling setting. If the
temperature is set at 90°F (32°C) the system
remains at the maximum heat setting. Choosing
either maximum setting does not cause the vehicle
to heat or cool any faster.
Do not cover the sensor located on the top of the
instrument panel near the windshield. This
sensor regulates air temperature based on the
intensity of the sun.
Also do not cover the sensor grille on the lower
right side of the climate control faceplate, as
this regulates the inside temperature.
To avoid blowing cold air at engine start-up in cold
weather, the system delays turning on the fan
until warm air is available. The length of delay
depends on the engine coolant temperature. Turning
the fan knob overrides this delay and changes
the fan to the selected speed.

Engine Coolant Temperature
Warning Light
This light indicates that the
engine coolant has
overheated or the radiator
cooling fan is not
working.
This light comes on briefly when the engine is started. If
it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally the
indicator light goes off.
If the light comes on and the vehicle has been operating
under normal driving conditions, pull off the road, stop
the vehicle, and turn off the engine as soon as possible.
SeeCooling System on page 6-22for more information.
Tire Pressure Light
For vehicles with a tire pressure monitoring system, this
light comes on briefly when the engine is started. It
provides information about tire pressures and the Tire
Pressure Monitoring System.
When the Light is On Steady
This indicates that one or more of the tires are
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC) on page 4-37for more
information. Stop and check the tires as soon as it is
safe to do so. If underinflated, inflate to the proper
pressure. SeeInation - Tire Pressure on page 6-49for
more information.

Hill and Mountain Roads
Driving on steep hills or through mountains is different
than driving on flat or rolling terrain. Tips for driving
in these conditions include:
•Keep the vehicle serviced and in good shape.
•Check all fluid levels and brakes, tires, cooling
system, and transmission.
•Going down steep or long hills, shift to a
lower gear.
{WARNING:
If you do not shift down, the brakes could get so
hot that they would not work well. You would then
have poor braking or even none going down a hill.
You could crash. Shift down to let the engine
assist the brakes on a steep downhill slope.
{WARNING:
Coasting downhill in N (Neutral) or with the ignition
off is dangerous. The brakes will have to do all the
work of slowing down and they could get so hot
that they would not work well. You would then
have poor braking or even none going down a hill.
You could crash. Always have the engine running
and the vehicle in gear when going downhill.
•Stay in your own lane. Do not swing wide or cut
across the center of the road. Drive at speeds
that let you stay in your own lane.
•Top of hills: Be alert — something could be in your
lane (stalled car, accident).
•Pay attention to special road signs (falling rocks
area, winding roads, long grades, passing or
no-passing zones) and take appropriate action.

Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 6-14
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it
again, keeping the tip down and check the level.

Automatic Transmission Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid loss.
If a leak occurs, take your vehicle to the dealer/retailer
and have it repaired as soon as possible.
Change the fluid and filter at the intervals listed in
Scheduled Maintenance on page 7-3, and be sure to
use the transmission fluid listed inRecommended Fluids
and Lubricants on page 7-10.
Notice:Use of the incorrect automatic transmission
uid may damage the vehicle, and the damages may
not be covered by the vehicle’s warranty. Always
use the automatic transmission uid listed in
Recommended Fluids and Lubricants on page 7-10.
