Question Answer
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:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the on position
(when the engine is not running), or in a position between on and start,
or by applying the parking brake when the ignition is turned to the on
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level and the
brake system should be inspected immediately by your authorized dealer.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Have the vehicle checked by your authorized dealer. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.
Airbag readiness:If this light fails
to illuminate when the ignition is
turned to the on position, continues
to flash or remains on, have the
system serviced immediately by your authorized dealer. A chime will also
sound when a malfunction in the supplemental restraint system has been
detected.

WARNING:Reclining the seatback can cause an occupant to
slide under the seat’s safety belt, resulting in severe personal
injuries in the event of a collision.
WARNING:Sitting improperly out of position or with the seat
back reclined too far can take off weight from the seat cushion
and affect the decision of the passenger sensing system, resulting in
serious injury or death in a crash. Always sit upright against your
seatback, with your feet on the floor.
WARNING:To reduce the risk of possible serious injury: Do not
hang objects off seat back or stow objects in the seatback map
pocket (if equipped) when a child is in the front passenger seat. Do
not place objects underneath the front passenger seat or between the
seat and the center console (if equipped). Check the “passenger airbag
off” or “pass airbag off” indicator lamp for proper airbag status. Refer
toFront passenger sensing systemsection for additional details.
Failure to follow these instructions may interfere with the front
passenger seat sensing system.
The control is located on the outboard side of the seat cushion.
Press to raise or lower the front
portion of the seat cushion.
Press to raise or lower the rear
portion of the seat cushion.

SAFETY RESTRAINTS
Personal Safety System
The Personal Safety Systemprovides an improved overall level of
frontal crash protection to front seat occupants and is designed to help
further reduce the risk of airbag-related injuries. The system is able to
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 may activate 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.
Front crash severity sensor
The front crash severity sensor enhances the ability to detect the
severity of an impact. Positioned up front, it provides valuable
information early in the crash event on the severity of the impact. This
allows your Personal Safety Systemto distinguish between different
levels of crash severity and modify the deployment strategy of the
dual-stage airbags and safety belt pretensioners.
Driver’s seat position sensor
The driver’s seat position sensor allows your Personal Safety Systemto
tailor the deployment level of the driver dual-stage airbag based on seat
position. The system is designed to help protect smaller drivers sitting
close to the driver airbag by providing a lower airbag output level.
Front passenger sensing system
For airbags to do their job they must inflate with great force, and this
force can pose a potentially deadly risk to occupants that are very close
to the airbag when it begins to inflate. For some occupants, like infants
in rear-facing child seats, this occurs because they are initially sitting
very close to the airbag. For other occupants, this occurs when the
occupant is not properly restrained by safety belts or child safety seats
and they move forward during pre-crash braking. The most effective way
to reduce the risk of unnecessary injuries is to make sure all occupants
are properly restrained. Accident statistics suggest that children are
much safer when properly restrained in the rear seating positions than in
the front.
WARNING:Air bags can kill or injure a child in a child seat.
NEVERplace a rear-facing child seat in front of an active air
bag. If you must use a forward-facing child seat in the front seat, move
the seat all the way back.
