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.

components: Engine oil level gauge, air filter casing, and sound absorbing materials
for dash panel
Components made

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
M2000028000528
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).

TECHNICAL FEATURES

IMPROVED SERVICEABILITY
•Employment of an automatic hydraulic timing belt
tensioner offers timing belt reliability, reduced
operating noise, and better serviceability. <4G1>
•Wiring harness section of the crank angle sensor
has been moulded integrally with the timing belt
cover, improving serviceability and reliability.
<4G1>
•Due to the adoption of the timing chain and the
timing chain tensioner, maintenance-free and reli
-
ability have been improved. <4A9>
•Since adoption of unvolatile memory (EEPROM*)
helps the learned value not to be initialised when
the battery terminal or connector of the control
unit is disconnected, maintainability can be
improved.
NOTE: *EEPROM: Electrical Erasable Programma-
ble ROM (information to be memorised can be
electronically written into and erased from ROM)
•Since the adoption of electric power steering
makes hydraulic pipes and oil pumps unneces
-
sary, maintainability can be improved.
•Employment of operative A/C piping layout and
refrigerant leak detection system enhances serv
-
iceability.

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.
