IMPACT SAFETY BODY, RISE*
NOTE: RISE*: Reinforced Impact Safety Evolution
The front and rear structures to absorb high energy,
and the highly tough cabin structure reduce the risk
of passenger injuries at front-, rear-, and side-impact
collisions, secure the space for life protection, and
facilitate rescuing passengers.

POWER WINDOW WITH SAFETY MECHA-
NISM
The power window with safety mechanism has been
adopted to automatically roll down and stop the door
window glass as soon as the occurrence of jamming
is detected at the time of rolling up the door window
glass.
SUNROOF WITH SA FETY MECHANISM
The sunroof with safe ty mechanism has been
adopted so that the roof lid glass can move in the
reverse direction and stop when application of exter
-
nal force hinders the movement during the sliding to
close or tilt down operation.
TRIMS AND HEADLINING
The head impact absorption structure has been
adopted for the pillar trim, quarter trim, and headlin
-
ing so that impact towards the head of a passenger
can be reduced.

IMPROVEMENT ON RECYCLING EFFICIENCY
ClassificationMain Components
Components made
of recycled
materialsChip materials produced during manufacturing process has been reused as the
following components: Door inside handle, bu mper, radiator grille, instrument panel,
door trims, or floor padding.
Waste materials produced by other i ndustries have been reused as the following
components: Engine oil level gauge, air filter casing, and sound absorbing materials
for dash panel
Components made
of materials which
can be easily
recycledThermoplastic resin has been utilised as the following components: Inside door
handle, bumper, radiator grille, instrument panel, door trim
Thermoplastic resin has been utilised as t he following components: Vacuum hose for
engine control, air intake hose, hood weather strip, tailgate opening weather strip
REDUCTION OF MATERIAL BURDEN ON ENVIRONMENT
ItemMain Components
Elimination of
environmental
burden materialsLead-free materials have been utilised as the following components: Radiator, fuel
tank, power steering oil pressure hose, el ectrodeposition paint for body, glass ceramic
print, heater core, battery terminals, wiring harness
Non-asbestos material has been used for engine gaskets.
PVC(polyvinyl chloride)-free materials ha ve been used for the waterproofing film.
Prevention of
ozone depletionAir conditioner filled with new refrigerant (HFC 134a) has been installed.
Prevention of air
pollutionEmployment of a metal cylinder head gasket reduces the volume of incomplete
combustion generated between the cylinder block and cylinder head, and suppresses
the level of unburned hydrocarbon (HC).
SERVICEABILITY AND RELIABILITY

MULTI USE TESTER-III (M.U.T.-III) SUB
ASSEMBLY
Comprehensive improvements have been made to
the M.U.T.-II, a tester for diagnosing problems with
the electronic control system. For easier servicing,
the newly developed M.U.T.-III has greatly improved
functions and is much easier to use. The M.U.T.-III
expands the functions of the M.U.T.-II in the following
ways:
1.CAN* bus diagnosis
•Auto diagnosis function for the CAN commu-
nications bus line is added.
NOTE: *CAN: Controller Area Network (for further
details, refer to GROUP 54C
P.54C-2).

GENERAL INFORMATION
POWER PLANT MOUNT32-2
GENERAL INFORMATION
M2320000100663
An inertia main shaft 3-point support type has been
adopted as an engine mount system, which has the
following features.
•By optimising the 3-point mount layout, the idling
vibration and acceleration noise are decreased
drastically.
•The transmission mounting insulator is built into
the body side member in order to absorb the
vibration transmitted from the engine efficiently.
•By connecting the engine roll stopper rod assem-
bly to the high-rigidity front axle No.1 crossmem-
ber, the vibration transmitted from the engine is
decreased.

GENERAL INFORMATION
POWER STEERING37-2
GENERAL INFORMATION
M2370000100851
Electric power steering system has been adopted for
all models in order to ensure an optimised steering
feeling.
FEATURES
•Improved fuel consumption by reduction of
engine load, and weight saving by decrease of
the number of parts have been achieved with the
introduction of the electric power steering system.
•3-spoke type steering wheel integrated with an
SRS airbag has been adopted.
•Impact-absorbing mechanism and tilt steering
mechanism have been adopted.
