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.

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
•The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in the ON/RUN and the light is not on.
•The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if the battery has recently been
replaced or if the battery has run down. The
diagnostic system is designed to evaluate critical
emission control systems during normal driving. This
can take several days of routine driving. If this
has been done and the vehicle still does not pass
the inspection for lack of OBD II system readiness,
your dealer/retailer can prepare the vehicle for
inspection.
Oil Pressure Light
If the vehicle has low
engine oil pressure, this
light stays on after
the engine is started, or
comes on and a chime
sounds while driving
the vehicle.
{WARNING:
Do not keep driving if the oil pressure is low. The
engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.

Auto Stop Mode
The AUTO STOP indicator on the tachometer shows
that the engine is stopped and is in the fuel saving
mode.
When the ignition key is turned off, the tachometer
needle drops to the OFF indicator.
If the ignition is on, the vehicle is in AUTO STOP, and
the driver’s door is opened, a chime sounds.
Charge/Assist Gage
The CHARGE/ASSIST
gage displays the charge,
into and out of the
hybrid battery.
When the gage indicates ASSIST, the electric motor
assists for maximum acceleration.
When the gage indicates CHARGE, the electric motor
operates as a generator to perform regenerative braking
while decelerating. SeeRegenerative Braking on
page 3-30for more information.
The gage also indicates CHARGE when the system is
recharging the hybrid battery.
If the hybrid battery or other hybrid components are
very hot or cold, the CHARGE and ASSIST functions
may be suspended until the component temperatures
are normal. United States

KEY FOB BATT (Battery) LOW
This message displays if the Remote Keyless Entry
(RKE) transmitter battery is low. Replace the battery in
the transmitter. See “Battery Replacement” under
Remote Keyless Entry (RKE) System Operation on
page 3-4.
LOW FUEL
This message displays when your vehicle is low on fuel.
Refill the fuel tank as soon as possible. SeeFuel

LOW TRACTION
This message displays and the ESC/TCS light on the
instrument panel cluster flashes when the system
is actively limiting wheel spin. Slippery road conditions
