Electric Power Steering System
11-1
INTRODUCTION
Our vehicle is equipped with Electric Power
Steering System (EPS). To keep reliability of
EPS during operation, please correctly use
EPS system according to the following
descriptions and keep up with daily inspections
and maintenance.
T h i s c h a p t e r a l s o p r o v i d e s i m p o r t a n t
information to safely use the EPS system. If
you encounter any problems during operation or
maintenance, please consult your local dealer.
ADVANTAGES OF EPS SYSTEM:
1) High efficiency. Traditional hydraulic power
steering systems are connected by
mechanical and hydraulic systems and are of
low efficiencies; usually 60%-70%. However,
the EPS system is connected by a
mechanical and electric motor and it has a
much higher efficiency of up to 90%.
2) The EPS system starts the motor only when it
needs to generate power without increasing
fuel consumption.
3) The power of the EPS system is controlled by
software, so that the vehicle can be operated
with power steering at various speeds.
4) The EPS system, uses a rigid connection
system, so the impact of road conditions on
steering wheel is greatly decreased.
No pollution to environment. For the
traditional hydraulic power steering system,
the hydraulic circuit has hydraulic hose and
fittings inside the system so oil leaks may
occur, and hydraulic hoses are not
recyclable. This system type can produce
pollution to the environment. However,
the EPS system does not cause pollution to
the environment.
5) If the engine does not start, the EPS system
can also work off the battery, and once
sufficient power is generated, the power
steering system is function able.
IMPORTANT INFORMATION
FOR SAFETY:
This vehicle is equipped with EPS system,
please read this chapter carefully before
operating the vehicle, and only when you are
familiar with and master the EPS system
methods and precautions. Make inspections of
the EPS system at regular intervals to ensure
