ABS FAQ 

1. What is ABS? 

ABS is an acronym for “Anti-lock Brake System”, which serves to ensure optimal 

braking distance and excellent brake stability and steerability on all kinds of road 

surfaces. 

 

2. What does ABS do for me? 

ABS offers an important safety advantage by preventing the wheels from locking 

during emergency braking situations which will cause loss in steering control of front 

wheel and offtracking or side skidding of rear wheel, allowing drivers to maintain 

control over steering and operate vehicles more effectively to steer around obstacles. 

 

3. How do I know if the vehicle I’m driving has ABS? 

Two methods recommended: 1. check your dashboard for a shortly lighted ABS 

warning light; or 2. simply ask your dealer. 

 

4. How does ABS work? 

The electronic control unit in ABS modulates brake pressure at all four wheels 

through an electromagnetic valve according to signals sent by wheel speed sensors 

and some certain control logics, just like the way an experienced driver pumps brake 

pedal, the difference is that a computer reacts much quicker than human brains, and 

the effect is also much better. 

 

5. How do I know my ABS is working? 

You will hear a mechanical sound and feel some pulsation in brake pedal when ABS 

is working. It is important not to take your foot off the brake pedal when you hear 

noise or feel vibrations, but instead continue to apply firm pressure.

6. Do cars with ABS stop more quickly than cars without it?   

Under most conditions the answer is yes, especially on snow-covered or wet road 

surfaces. However, don’t forget to steer around any obstacles you see on the roads. 

 

7. What if ABS fails? 

ABS warning light goes on once ABS fails. In this case ABS is deactivated, while 

conventional brake system remains undamaged, which means you still can brake 

following normal procedure. 

 

8. When does ABS warning light go on? 

ABS warning light goes on for about 1.7 seconds after starting vehicle, and then goes 

out. After that, the light will go on only when ABS failure occurs. Therefore, you are 

supposed to go to service station once the light goes on again, and any DIY repair of 

ABS is not recommended.

“Four Dos” and “Four Don’ts” of ABS 

 

“Four Dos” 

Do keep your foot on the brake pedal. Maintain firm and continuous pressure on the 

brake while steering to enable four-wheel ABS to work properly.   

Do allow enough distance to stop. Allow three seconds or more braking time when 

driving under good conditions after vehicles. Allow more time if conditions are 

hazardous. 

Do practice driving with ABS. Become accustomed to pulsations that occur in the 

brake pedal when ABS is activated. Empty parking lots or other open areas are 

excellent places to practice emergency stops. 

Do consult the Driver’s Manual for additional driving instructions on the anti-lock 

brake system. 

 

Four “Don’ts” 

Don’t drive an ABS-equipped vehicle more aggressively than vehicles without ABS. 

Driving around curves faster, changing lanes abruptly or performing other aggressive 

steering maneuvers is neither appropriate nor safe with any vehicle. 

Don’t pump the brakes. In ABS-equipped vehicles, pumping the brake turns the 

system on and off, which might result in weakening braking performance and increase 

of braking distance. ABS pumps the brakes for you automatically at a much faster rate, 

and allows better steering control. 

Don’t forget to steer. ABS enables drivers to steer in emergency braking situations, 

but the system itself does not steer. 

Don’t be alarmed by mechanical noises and/or slight pedal pulsations while applying 

the brake in an ABS-equipped vehicle. These conditions are normal and let the driver 

know ABS is working.
