o-4GENERAL - Technical Features
BASIC CONSTRUCTION
The 4WD vehicles are equipped with
2.OL DOHC
16-valve turbocharged engine and incorporate new
technologies such as full time 4WD of center
differential type with viscous coupling differential
limiting for excellent running stability and excellent
Steering
l Light weight and compact rack and pinion
type for high steering response
l Tilt steering mechanism to give optimum
driving position
\driving across bad roads, and $-wheel independent
suspension for comfortable riding.
Adopted on
2WD vehicles are 2.OL DOHC 16-valveengine, MacPherson strut type front suspension
and torsion axle
typ.e 3-link rear suspension.
Rear suspension
l Self-aligning double wishbone type suspen-
sion for comfortable ride
(4WD)l Torsion axle type 3 link suspension for
outstanding driving stability
(2WD)l Negative chamber for outstanding steer-
ability during high speed driving
0 Anti-lift geometry for high stability duringbraking
lIntegral torsional bar type axle beam for
optimum roll stiffness (2WD)
\Front propeller shaft (3-piece
4-joint type)
lRobro joint to absorb lengthwise and angular
change and prevent transmission of vibrations.
(4WD)
IFront suspension
The front suspension of McPherson strut type
independent suspension system
l Under steer geometry for outstanding steering
stability
l Negative offset geometry for outstanding
stabil-ity at braking
0 Offset coil springs for comfortable ride
Brakes
l Cross piping dual type proportioning valvethat keeps balanced braking power even at
failure of the hydraulic system.
l Four wheel disc brake system for high
braking power.

GENERAL - Technical Featureso-5ENGINE
The engines are the transverse-mounted engine
especially for front-engine/front-wheeldrive orfront-engine/4-wheel drive models, the
2.OL DOHC
16-valve engine with high-performance, silent-
operation,low-vibration,low-noise,low-fuel-
consumption features, an engine that fully displays
the most
up-todate engine technology.

FEATURESHigh performance and low fuel consumption
l The rocker arm reduces the valve-actuation torque as well as fuel consumption.
l Air-intake efficiency improved through the adoption of the optimum air-intake system layout.
l Improved response and fuel consumption has been achieved by electronic control multipoint
fuel injection.
l Water-cooled turbocharger.
Quiet operation
l Noise and vibration have been decreased by the adoption of roller rocker arms.
l Noise generated by the valve mechanism has been decreased by the hydraulic auto lash adjusters.
l Vibrations have been decreased by the adoption of bearing caps with beams which increase the
rigidity of the crankshaft support points.
-Serviceability
l Complete self-diagnosis functions.
l Enhanced reliability through the adoption of gold-plated connector terminals.
l Use of an auto tensioner achieves maintenance-free, automatic adjustment of timing belt
tension.
l Use of the auto lash adjusters achieves maintenance-free, automatic adjustment of valve clearance
.o The 2coil ignition system without a distributor supplies sufficient ignition energy even during
high speed operation.

GENERAL -Technical Featureso-74WD
(Four-wheel drive)The full time 4WD system adopts viscous coupling
unit (VCU) as the differential limiting device for thecenter differential of 4WD vehicle to achieve auto-
matic and ideal distribution of engine torque to the
front and rear wheels.

O-8GENERAL - Technical FeaturesTHEFT-ALARM SYSTEM (OPTION for4WD
VEHICLES)To make the vehicle theftproof, this system is so
designed that the headlights go on and off and the
horn is sounded intermittently for ‘about threeminutes when the locked door, hood or liftgate has
been forced open without using a key.
Furthermore, the starter circuit is interrupted so that
the engine may not be operated, making the vehicle
theftproof.
About 20 seconds after all doors are closed
and locked, the rear hatch is closed, and the
hood is closed---t SYSTEM ARMED4uthorized
