FEATURES
WEIGHT REDUCTION AND HIGH RIGID-
ITY
•Application ranges of high tension steel plate,
antirust steel plate, and uneven thickness steel
plate have been expanded.
•The upper frame outer and front pillar connection
has been strengthened by adopting the upper
frame-to-front pillar brace.
•The radius of each opening corner for the doors
and tailgate has been enlarged.
•Cowl top lower panel and spring house panel are
directly joined for higher rigidity.
•Strut tower bar has been adopted <4G1>.
•A front suspension axle side plate has been
adopted <4G1>.
•The air outlet garnish has been installed to the
hood, improving the sporty image and cooling
efficiency in the engine compartment. <4G1>
REDUCTION OF VIBRATION, NOISE, AND
AERODYNAMIC NOISE
•Straight frame structure has been adopted.
•Curved front floor and uneven thickness steel
plate have been adopted.
•Rigidity of the suspension installation part has
been improved.
IMPROVEMENTS IN SAFETY
•RISE (Reinforced Impact Safety Evolution) has
been used for the main body.
•Features a side door beam to boost safety upon
side impact.
•Direct combination key cylinder and inside lock
cables for the front doors have been adopted to
improve safety upon impact.
IMPROVEMENTS IN OPERATION
QUALITY
•The central door locking system, which
locks/unlocks all the doors and the tailgate, is
adopted.
•"P" position shift linked door-unlock function has
been introduced to the central door locking sys
-
tem(F1C1A).
IMPROVEMENTS OF PRODUCT
PACKAGE AND APPEARANCE
•Rigidity of door sash bottom section has been
improved.
•By improving the engaging sound between the
door latch and striker, the door locking sound
quality has been enhanced.
•UV & heat protect glass has been used for the
windshield.
•UV-reducing glass has been used for the front
door window glasses and rear door window
glasses.
•Privacy glasses have been used for rear door
window glasses, quarter window glasses, and
tailgate window glass (Option).
•Multi-mode keyless entry system (with door mir-
ror retraction/return control function) has been
adopted.
•Protector film has been attached on side sill
.
•Sunroof has been installed (Option).

GENERAL INFORMATION

The cooling system is a water-cooled pressurized,
forced circulation type which offers the following fea
-
tures:
•To stabilize engine coolant temperature, the ther-
mostat is located at the coolant inlet port from the
radiator.
•To improve engine cooling performance and save
weight, a plastic radiator tank and aluminium radi
-
ator fins are used.
•In order to save the weight, the A/C condenser
fan has been abolished, and one-fan system has
been adopted to secure sufficient cooling effect
using the radiator fan only.
•A radiator condenser tank integrated with a radia-
tor has been adopted in order to save the weight.
•A cross flow type radiator assembly whose tanks
are installed on the both sides of the radiator fins
has been adopted in order to decrease the over
-
all height of the radiator and improve the aerody-
namic performance.
•Sufficient radiator fin area and cooling fan diame-
ter are secured, and the radiator fin pitch is
increased. As a result, the capacity of the cooling
fan motor is reduced cutting down the power con
-
sumption, and the noise and weight of the cooling
fan are reduced.
