FEATURES

Power steering has been adopted in all vehicles to
make the steering system easier to handle.

•

A 4-spoke steering wheel is used.

•

A steering column has a shock absorbing
mechanism and a tilt steering mechanism.

•

Integral-type rack and pinion gear with high
rigidity and excellent response is used.

•

A vane type pump with a fluid flow rate control
system which change steering effort according to
the engine speed is used.

•

The separate plastic resin oil reservoir is used to
reduce weight and to make the fluid level
checking easier.

•

The cooler tube assembly is installed on the
power steering fluid line to improve the cooling
performance of the power steering fluid.
