ABS FAQ

●What is ABS?

ABS is abbreviation of Anti-Lock System. ABS ensures to maintain good braking stability and cornering while

keeping optimum braking distance on various road surfarces.

●Why use ABS?

During braking, vehicle will lose steering ability when front wheel lock and vehicle will slid when rear wheel block.

ABS will ensure your control to vehicle when braking by preventing wheel from blocking. With ABS function, driver can

bypass obstacles on way.

How to tell if an ABS installed?

Two methods recommended：

Firstly, check if there is a short lighting ABS warning light on instruments panel or switches panel;

Secondly, consult from the dealer.

● How ABS operate?

Upon wheel speed sensor signal and certain control logic, ABS ECU controls each wheel brake channel pressure

through solenoid valve repeatedly regulating.

●How to tell if ABS is operating?

When ABS operating, brake pedal vibrating will be felt and ECU operating sound will be heard

Warning: DO NOT be afraid at this moment, DPRESSED brake pedal firmly and keep pedal depressed.

● Is an ABS installed vehicle braking distance shorter than a vehicle without ABS?

In most cases, YES, especially on an icy, snowy or a wet road surface. DO NOT forget to turn steering wheel to

bypass obstacles on way even under crucial circumstances.

●How if ABS fail?

If ABS fails, ABS warning light will be on steadily，ABS will not work but conventional brake still operates. You may

brake as per conventional braking method.

When ABS warning light turns on?

ABS warning light goes on for 1.7 second and then off after engine on. During driving, ABS will not go on until ABS

fails. Therefore, the fault must be repaired as soon as possible once ABS warning light goes on during normal driving

condition. We recommend you to repair the fault at vehicle service shop and do not try to repair ABS by yourself.

Precautions on ABS

4 MUST ITEMS

1、Depress brake pedal and keep pedal depressed firmly to obtain enough and consecutive braking force for ABS

operating effectively.

2、To keep enough braking distance, when driving on a good road surface, at least 3 seconds braking time must be left for

front vehicle and a longer braking time must be left when driving on a bad road surface.

3、Practice applying ABS brake beforehand, get familiar with and have adaptability to pedal vibrating while ABS

operating. Both parking lot and square are good places for practicing applying urgent ABS braking.

4、Carefully read DRIVER MANUAL for a good understanding of operating items provided by the vehicle manufacturer

who install the ABS system.

4 NOT ITEMS

1、DO NOT drive an ABS installed vehicle more careless than a vehicle without ABS. Even for an ABS installed

vehicle, a sharp cornering, fast way-changing way and other sharp steering operations are hazard and not recommended.

2、DO NOT depress brake pedal repeatedly. When driving an ABS installed vehicle, depressing pedal repeatedly will

cause ABS intermittent on, which will decrease braking efficiency and increase braking distance. Actually, ABS itself

increases and decreases brake force at a high-speed rate, and offers effective steering wheel control.

3、DO NOT forget to turn steering wheel. ABS offers effective steering wheel control ability, but cannot automatically

carry out steering operation itself.

4、 DO NOT be afraid of normal ABS hydraulic system operation sound and brake pedal vibrating whiling braking.

Such phenomenon is normal by which driver can feel ABS is operating.
