POWER STEERING
FEATURES
To improve steering feeling and response of the
steering system, the following steering system has
been adopted.
D
The system has been equipped with the MOMO
leather 3-spoke-type steering wheel with
built-in SRS airbag.
D
A steering column with a shock absorbing
mechanism and a tilt steering mechanism has
been adopted.
D
Integral-type rack and pinion gear with high rigidity
and excellent response has been adopted.
D
A variable capacity pump has been adopted to
reduce
power
losses
and
improve
fuel
consumption. When the engine speed increases,
the pump chamber capacity is reduced
proportionally so that only the necessary amount
of power steering fluid is discharged.
D
Improved the cooling efficiency of power steering
fluid by adopting a cooler tube to the fluid line.

STEERING WHEEL
There are two types of MOMO leather 3-spoke-type
steering wheels (built-in SRS air bag) with different
desigins.

<RS(option), RS-II>
STEERING SHAFT AND COLUMN
For the steering column, an impact absorbing
mechanism which absorbs impact energy in the
event of a collision as well as a tilt steering
mechanism which enables the driver to obtain an
optimum driving position have been adopted.
