Anti-lock braking systems (ABS) help you steer in emergencies by restoring traction to
your tires.

What It Does

What It Does: Helps prevent wheels from locking up – possibly allowing the driver to
steer to safety.

back – that’s normal.

How it works

WHAT IT DOES
Four-wheel anti-lock brakes help you steer as you brake during an emergency.

THE TECHNOLOGY BEHIND IT

Wheel sensors detect when your car’s tires begin locking up. Then, they rapidly apply and
release (pulse) the brakes to automatically keep your tires from skidding.

5/7
WHAT YOU NEED TO DO
When you feel or hear the ABS vibrating, continue to firmly press and hold the brake
– then steer to safety.

TIPS FOR USING

If your car doesn’t have 4-wheel ABS or the ABS is not working, make sure to pump
the brakes if your car begins to skid.
ABS works most effectively when the tires are properly inflated and in good
condition.
Common causes of 4-wheel ABS malfunctions include worn brake linings and air or
dirt in the brake fluid.
