[Information Screen]
This screen indicates the direction of energy trans-
mission. It is also possible to check the current drive
method (engine, motor or both) and status of power
generation by the engine and that of charging regen-
erative energy.
This screen indicates the average fuel consumption,
amount of recovered energy and fuel consumption for
that moment. Average fuel consumption is displayed
at 5-minutes intervals. The recovered energy display
indicates the amount of energy recovered over the past
5 minutes, with each mark representing 50Wh.

A range of features for comfort - the more you use them,
the better they get.
Multi-Information Display

The 5.8º wide touch panel type multi-information color LCD
is standard.

Energy monitor, fuel consumption and other vehicle information
screens, audio operation status and audio operation screen can
be indicated on the multi-information display. The outside tem-
perature are also indicated on the screen.
[Audio system]

An AM/FM cassette and 4-speaker system compatible with the
multi-information display has been adopted.

As the touch panel type display is used to operate the audio sys-
tem, the multi-information display simultaneously indicates the
operating status of the audio system.

The antenna provided is a collapsible style pole antenna posi-
tioned at the center of the roof.
[GPS Voice Navigation]

A GPS (Global Positioning System) voice navigation system
is optional.

The multi-information display can show the map on favorite
type among turn list, arrow display and enlarged intersection.

Using DVD (Digital Versatile Disk) as a memory source for map
data, a large quantity of information can be processed.

Head Impact Protection Structure
The construction of the pillar trims and roof side adopted gives full consideration to protecting the heads of
the driver and passengers from injury in the event of a collision. In addition, impact absorbing material has
been built into the interior of each pillar trim and roof side which are most likely to be the cause of head
injuries in a collision.
SRS Airbag
SRS airbags are standard for the driver and front passenger seats on all models. In the event of a frontal collision,
the airbags function to support the seatbelts in reducing the impact to the driver and front passenger. Also,
SRS side airbags are available as a option. The SRS side airbags have been designed to help reducing the
impact energy that is transmitted to the driver and front passenger in the event of a side collision.
Seatbelt with Pre-tensioner and Force-limit-
ing Mechanism
Three-point type seatbelts with pre-tensioner and force limiter are standard on the front seats of all models.
An ELR-equipped seatbelt is provided on the driver's side and an ALR/ELR selectable one on the passenger
side.
Three sets of 3-point type
ALR/ELR selectable seatbelts are fitted on the rear seats.

2. Body Shell

The joining construction (A-A cross section) of the cowl side panel, front pillar, and the instrument panel
reinforcement has been optimized to restrain the generation of vibrations.

By joining the under body and the front pillar with a pillar brace (B-B cross section), as well as the upper
end of the front pillar with the roof header (C-C cross section), the generation of vibrations has been re-
strained.

By providing a gusset (D) in the quarter wheel house and a reinforcement (E) in the upper back panel, the
generation of vibrations in the rear body area has been restrained.

2) Impact Absorbing Structure for Side Collision
Impact energy of a side collision directed to the cabin area is dispersed throughout the body via pillar
reinforcements, side impact protection beams, floor cross members, thus helping minimize the impact
energy finally directed to the cabin. In addition, the body is made reinforced joints and high strength
sheet steel, in order to help maintain the maximum preservation of the cabin space. And, in order to
make the door energy absorbent, a closed cross section configuration is provided at the belt line area
of the front and rear doors.
By providing an energy absorbing urethane pad in the front door panel and an energy absorbing mate-
rial in the door panel and the center pillar garnish, the impact of a collision can be dampened.
A head impact protection structure has been adopted. With this type of construction, if the occupant's
head hits against the roof side rail and pillar in reaction to a collision, the inner panel of the roof side
rail and pillar collapses to help reduce the impact.

RUST-RESISTANT BODY
1. General
Rust-resistant performance is enhanced by extensive use of anti-corrosion sheet steel and an anti-corrosion
treatment by applying wax, sealer and anti-chipping paint to easily corroded parts such as the hoods, doors
and rocker panels.
2. Anti-Corrosion Sheet Steel
Anti-corrosion sheet steel is used in all areas other than the roof and interior parts.

LOW VIBRATION AND LOW NOISE BODY
1. General
Effective application of vibration damping and noise suppresant materials reduces engine and road noise.
2. Sound Absorbing and Vibration Damping Materials

Adoption of the dash panel silencer made the reduction of the engine and road noise and improved the
quietness in the compartment.

Foamed urethane sponge, foamed seal material, felt and roof silencer pad are applied onto the roof panel
and pillars to reduce wind and road noise.

The adoption of the floor silencer realized the reduction of the engine and road noise. Also, the adoption
of RSPP (Recycled Sound Proof Products) for raw material realized the improvement of recylability.
