operating the seat belt with pre -tensioner s.
SEAT BEL T RETRACT OR WITH FORCE

The driver ’s /front p asseng er’s seat belt retractor has
been e quipped with a force limit er. The force limiter
is a device which operat es when a predetermined
force is applied, an d limits the for ce.

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.

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

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

refer to the Workshop Manual.
SWS INPUT SIGNAL CHECK USING
M.U.T.-III
When the M.U.T.-III is connected to the diagnosis
connector and any of the SWS-linked switches is
operated, the PC buzzer sounds to evaluate whether
the switch is normal or not.
SWS INPUT SIGNAL CHECK AND ECU

The switch signals sent by ECUs and the operations
of these ECUs can be confirmed by using the SWS
monitor and the M.U.T.-III.
