transaxle unit, unlike the conventional MMC engine,
is arranged with the engine on the passenger side
and the transaxle on the driver’s side.

PASSIVE SAFETY
Supplemental Restraint System (SRS)
An airbag module has been provided for both the
driver’s and front passenger’s seats for safety of
the driver and front passenger. The driver’s seat
airbag module is mounted at the center of the steer-
N70AGOOAA
ing wheel, whereas the front passenger’s seat airbag
‘d
module is mounted in the instrument panel above
the glove compartment. As soon as a frontal collision
over a design G-force is detected, the
airbags inflate.

ENVIRONMENTAL CONSIDERATIONS
To meet the growing world-wide demands for saving
resources and protecting global environment, spe-
cial considerations have been incorporated to make
the ECLIPSE friendly to driver and passengers and
to the earth.
Considerations for recycling
(1) Recyclable thermo-plastic material has been
extensively used.
(2) The names of the material have been marked
on the plastic parts to facilitate recycling.
(3) Recycled materials (regenerated materials)
have been used wherever possible.
air flow
N7OAJOOAA
Protection of global environment
(1) Use of non-asbestos material for gaskets and
pads
(2) Non-Freon parts
l
Use of Freon has been limited to the neces-
sary minimum in the processes for manufac-
ture of seats, steering wheels, etc.
(3) Extending material life expectancies for less
waste
l
Anti-rust steel sheets have been used for
about 80% of the outer panels and major
members of the body.
l
Longer-life brake fluid and coolant additives
are used
(4) Better fuel economy by reducing friction and
weight in various areas
‘d

GENERAL - Technical Features
o-13
Use of maintenance-free parts
i
(1) Auto-lash adjusters have eliminated the need
for adjustment of valve clearance.
(2) An auto-tensioner has been adopted to elimi-
nate the need for adjustment of the timing belt
tension.
(3) The improved mounting accuracies of the cam-
shaft position sensor and crank angle sensor
Increased diagnostic items
The diagnostic functions for the following system
have been added so that the diagnostic trouble
codes and service data for them can be read and
actuator tests performed by use of the Scan tool
(MUT-II).
Better serviceability and easier handling
(1) The engine oil and ATF level gauge grips have
been changed to resin ones for easier handling.
The name has been marked on each grip for
identification.
(2) The fuel gauge unit and related parts have been
made demountable and remountable through
the service hole under the rear seat cushion.
(3) Both the front and rear hubs have been bolted
to the knuckles for easier demounting and
re-

mounting.
(4) When an ABS wheel speed sensor is mounted,
there is no need for adjustment of the clearance
between the sensor and rotor.

tion timing.
(4) The plastic region angle method has been
adopted for tightening the cylinder head bolts.

(5) Headlight aiming adjustment can be easily per-
formed from above the light, using a cross-
pointed screwdriver.
(6) An electric type speedometer has been adopted
for easier demounting and remounting of the
speedometer, instrument panel, transaxle, etc.
(7) The luggage compartment floor board can be
held raised so that the spare wheel, tools, etc.
can be conveniently taken out and stored.
