Driving safety system
In order to improve the driving safety, the following driving safety system will automatically
will be operated automatically based on various driving conditions. However, keep in mind
that these systems are only used to provide the assist functions and should not be overly
dependent during driving process.
ABS (Anti-lock Brake System)
■
There are two circuits (x-type
arrangement) in the hydraulic
system of ABS to drive the brake.
One circuit is used to connect the
front left wheel brake to the rear
right wheel brake, and the other
circuit is used to connect the front
right wheel brake to the rear left
wheel brake. If one circuit is faulty,
there are still two wheels that can
be braked.
■
ABS can be used to prevent wheel locking or slipping when the brake is applied
suddenly or applied on slippery roads, to maintain the steering control.
■
If the front wheels are slipping, the steering will not be controlled, that is, the car will be
still driven straight forward when turning the steering wheel. ABS can be used to
prevent the wheel locking and maintain the steering control because its pulse fast
braking reacts much faster than manual operation.
■
Do not depress the brake pedal in pulse mode; otherwise, ABS will be faulty. When
turning the steering wheel to avoid a danger, a strong and stable pressure should be
applied on the brake pedal to play the role of ABS. This is the so-
called “Steady
Depressing and Careful
Turning”.
■
When ABS is operated, you will feel a vibration and hear a noise from the brake pedal.
It is normal and is caused by the pulse fast braking of ABS. The operating speed of
ABS depends on the driving force (adhesion) of the wheels.
Important safety tips
■
ABS (Antilock Brake System) does not reduce the time and distance required to brake
the car. The device can only be used to control the steering during braking process.
Must maintain a safe distance from other cars.
■
ABS does not prevent the slippage caused by a sudden steering, such as quick turn or
sudden lane change. Regardless of road conditions and weather conditions, always
In front of
