Question Answer
What is the fan noise and slight
tapping sound I hear from the rear
of my hybrid?The fan noise comes from two fans
located inside the high voltage
battery. These fans turn on when
the battery requires cooling air.
The fan speed, and associated
noise level, will change according
to the amount of cooling required
to maintain good performance.
How far can I go in Electric Drive
if I run out of gas?Running out of gas is not
recommended. However, you may
be able to go about one mile,
driving at 30 mph (48 km/h), if the
battery has a normal state of
charge.
What is the engine oil change
service interval?The engine oil should be changed
every 10,000 miles (16,000 km)
under normal operating conditions.
See theScheduled maintenance
guidechapter.
Can I put E10 or E85 in my
vehicle, and how will it affect my
fuel economy?Your hybrid vehicle can use E10
(10% ethanol, 90% gasoline) fuel,
but you may notice slightly
reduced fuel economy because
ethanol contains less energy per
gallon than gasoline. Your hybrid
vehicle is not designed to use E85
(85% ethanol).
How long will my high voltage
battery last? Does it need
maintenance?The high voltage battery system is
designed to last the life of the
vehicle and requires no
maintenance.

Question Answer
Can you charge the battery with a
plug into an A/C outlet?There are no provisions for
charging the high voltage battery
from a power supply external to
the vehicle.
What is the purpose of the ECON
button?ECON mode may provide
improved fuel economy by
preventing the gasoline engine
from running for the sole purpose
of providing air conditioning. When
the engine turns off, the A/C
compressor does not operate and
warm air may come out of the
vents. In ECON mode, A/C
operates as normal when the
gasoline engine is running.
Can I tow the hybrid behind my
motor home with all four wheels
down?Yes. Your hybrid vehicle can be
“flat-towed” without modification.
See theRecreational Towing
section in theTires, Wheels and
Loadingchapter for more
information.

WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulbs work. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Check engine:TheCheck Engine
indicator light illuminates when the
ignition is first turned to the RUN
position to check the bulb and to
indicate whether the vehicle is ready for Inspection/Maintenance (I/M)
testing. Normally, the
Check Engine
light will stay on until the engine is
cranked, then turn itself off if no malfunctions are present. However, if
after 15 seconds the
Check Engine
light blinks eight times, it means
that the vehicle is not ready for I/M testing. See theReadiness for
Inspection/Maintenance (I/M) testingin theMaintenance and
Specificationschapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.

12.ECON:Press to activate/deactivate economy air conditioning
operation. ECON mode may provide improved fuel economy by
preventing the gasoline engine from running for the sole purpose of
providing A/C. When the gas engine turns off, the A/C compressor does
not operate to cool the cabin and comfort may be reduced. In ECON
mode, A/C operates as normal when the gasoline engine is running. To
prioritize cooling comfort over fuel economy, deactivate ECON. ECON
can not be selected in
(defrost) or(floor/defrost).
13.A/C:Press to activate/deactivate air conditioning. Use with
recirculated air to improve cooling performance and efficiency. Engages
automatically in AUTO,
(defrost) and(floor/defrost). Selecting
ECON mode affects A/C operation. Refer to ECON information previously
in this section.

Driver heated seat control (if equipped):Press to
activate/adjective the driver heated seat. SeeHeated seatsin the
Seating and Safety Restraintschapter.
Outside temperature:The outside temperature will appear in the
display and is labeled EXT TEMP.
Temperature conversion:To switch between Fahrenheit and Celsius,
refer toSetup menuin theMessage centersection of theDriver
Controlschapter.
Operating tips
•To reduce fog build up on the windshield during humid weather,
select
(defrost) or(floor/defrost).
•To reduce humidity build up inside the vehicle, do not drive with the
system OFF or with
(recirculated air) engaged and A/C off.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats by blocking the air from the rear seat floor
vents.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•To improve the A/C cool down, drive with the windows slightly open
for 2-3 minutes after start up or until the vehicle has been “aired out.”

analyze different occupant conditions and crash severity before activating
the appropriate safety devices to help better protect a range of
occupants in a variety of frontal crash situations.
Your vehicle’s Personal Safety Systemconsists of:
•Driver and passenger dual-stage airbag supplemental restraints.
•Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors.
•Driver’s seat position sensor
•Front passenger sensing system
•“Passenger airbag off” or “pass airbag off” indicator lamp
•Front crash severity sensor.
•Restraints Control Module (RCM) with impact and safing sensors.
•Restraint system warning light and back-up tone.
•The electrical wiring for the airbags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, front passenger sensing system, and indicator lights.
How does the Personal Safety Systemwork?
The Personal Safety Systemcan adapt the deployment strategy of your
vehicle’s safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
information to the Restraints control module (RCM). During a crash, the
RCM activates the safety belt pretensioners and/or either one or both
stages of the dual-stage airbag supplemental restraints based on crash
severity and occupant conditions.
The fact that the pretensioners or airbags did not activate for both front
seat occupants in a collision does not mean that something is wrong with
the system. Rather, it means the Personal Safety Systemdetermined
the accident conditions (crash severity, belt usage, etc.) were not
appropriate to activate these safety devices. Front airbags are designed
to activate only in frontal and near-frontal collisions (not rollovers, side
impacts or rear impacts) unless the collision causes sufficient
longitudinal deceleration. The pretensioners are designed to activate in
frontal, and in side collisions and rollovers.
Driver and passenger dual-stage airbag supplemental restraints
The dual-stage airbags offer the capability to tailor the level of airbag
inflation energy. A lower, less forceful energy level is provided for more
common, moderate-severity impacts. A higher energy level is used for
the most severe impacts. Refer toAirbag supplemental restraints
section in this chapter.

restrain children in the rear seat. The sensor also turns off the passenger
front airbag and passenger seat-mounted side airbag when the passenger
seat is empty.
When the front passenger seat is occupied and the sensing system has
turned off the passenger’s frontal airbag, the “pass airbag off” indicator
will light and stay lit to remind you that the front passenger frontal
airbag is off. SeeFront passenger sensing systemin the airbags section
of this chapter.
Front safety belt usage sensors
The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal Safety Systemto tailor the airbag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety restraintssection in this chapter.
Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions, and in side collisions and rollovers. This helps
increase the effectiveness of the safety belts. In frontal collisions, the
safety belt pretensioners can be activated alone or, if the collision is of
sufficient severity, together with the front airbags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant’s forward momentum. This helps
reduce the risk of force-related injuries to the occupant’s chest by
limiting the load on the occupant. Refer toEnergy management feature
section in this chapter.
Determining if the Personal Safety Systemis operational
The Personal Safety Systemuses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lightsection in theInstrument Clusterchapter.
Routine maintenance of the Personal Safety Systemis not required.
The Restraints control module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and front passenger sensing system. In addition, the
RCM also monitors the restraints warning light in the instrument cluster.
A difficulty with the system is indicated by one or more of the following.
