MIVEC (Mitsubishi Innovative Valve Timing Electronic
Control System)
M2132023500212
MIVEC is the system which continuously varies and
controls the opening and closing timings of the intake
valve and the exhaust valve.
System Configuration Diagram
MIVEC allows the optimum valve timing to be con-
trolled in accordance with the engine operation and
the idling stability to be improved, as well as the out
-
put and the torque to be better in all the operation
ranges.
•The ECM assesses the engine operation through
the signals from each sensor.
•Based on the assessed information, the ECM
sends the duty signal to the intake engine oil con
-
trol valve and exhaust engine oil control valve as
well as controls the spool valve position.
•Changing the spool valve position allows the oil
pressure to be divided into the retarded chamber
and the advanced chamber, as well as allows the
phases of the intake camshaft and the exhaust
camshaft to be continuously changed.

GENERAL INFORMATION
FOUR-WHEEL ANTI-LOCK BRAKE SYSTEM (4ABS)35B-2
GENERAL INFORMATIONM2351000100830
The ABS that ensures directional stability and con-
trollability during hard braking. ABS is standard
equippment on the ES and GTS models but is
optional.
This ABS uses a 4-sensor system that controls all
four wheels independently of each other, and has the
following features:
•EBD *1 (Electronic Brake-force Distribution sys-
tem) control that can obtain ideal rear wheel
brake force has been employed.
•The magnetic encoder for detecting the wheel
speed has been installed instead of the rotor as
the wheel speed sensor.
•For wiring harness saving and secure data com-
munication, CAN *2 bus has been adopted as a
tool of communication with other ECUs.
NOTE: .
•*1: EBD (Electronic Brake-force Distribution)
•*2: For more information about CAN (Controller
Area Network), refer to GROUP 54C
P.54C-2.

GENERAL INFORMATION
REAR SUSPENSION34-2
GENERAL INFORMATIONM2340000100977
The trailing arm type multi-link suspension is
adopted.
.
MAIN FEATURES
•The wheel tread is increased to improve corner-
ing ability.
•The roll center height is modified to improve the
steering ability.
•A double crossmember is adopted and the upper
arm, lower arm, toe control arm are joined to the
crossmember to improve suspension alignment
accuracy and maintenance performance.
•Improvement of arms installation accuracy elimi-
nates the camber adjustment to improve mainte-
nance performance.
•The trailing arm bushings are installed in the
upper position to improve the movement of the
suspension when the vehicle negotiates bumps
and increase riding comfort.
•Twin tube type shock absorber is adopted to
secure optimum rolling rigidity and improve the
steering ability.
•A high efficiency ball joint type stabilizer link is
adopted to improve steering ability.
•The toe control arm is installed in the lower posi-
tion to increase toe and camber rigidity and
improve steering ability.

GENERAL INFORMATIONM2330000100965
The MacPherson strut type suspension is adopted..
MAIN FEATURES
•The wheel tread is increased to improve corner-
ing ability.
•The roll center height is modified to improve the
steering ability.
•Increased suspension stroke improves road hold-
ing quality, and secures good adhesion even on
bumpy-rough roads to reduce shocks received
when the vehicle negotiates bumps.
•The fully flattened crossmember improves the
left/right direction rigidity of installation points of
the lower arms for high steering ability.
•Tuning of the lower arm bushes improves the
steering ability and riding comfort.
•The stabilizer bar is joined to the strut for high
efficiency to secure the optimum rolling rigidity,
and improves the steering ability.
•Total tuning of struts, springs, and bump rubbers
improves the steering ability and riding comfort.

GENERAL INFORMATION
REAR AXLE27-2
GENERAL INFORMATIONM2270000100478
The rear axle has the following features:
•The wheel bearing is a unit ball bearing (dou-
ble-row angular contact ball bearing) which incor-
porates the oil seals and is highly resistant to
thrust loads.
•The number of parts has been reduced by inte-
grating the magnetic encoder for ABS wheel
speed detection into the wheel bearing. -

STEERING WHEEL
POWER STEERING37-3
CONSTRUCTION DIAGRAM
STEERING WHEELM2370001000761
The steering wheel is designed to improve operabil-
ity, safety and maintainability and has the following
features:
•Newly designed Three-spoke type has been
adopted. For DE and ES, the steering wheel
made of urethane has been adopted. For GTS,
the steering wheel made of genuine leather has
been adopted.
•Audio remote control, voice control, and cruise
control switches are available on some models.
•Sporty and thick type grip shape has been
adopted.
•Rigid core metal reduces steering wheel vibra-
tion.
•It incorporates an SRS airbag to protect the driver
in the event of a frontal collision.
•The airbag module is equipped with an inflator
that does not contain sodium azide.
•Optimisation of the airbag specifications reduces
the risk of injury to the passengers in a collision.
