How should you use an anti-lock braking system in an emergency stop?
-
A.
Pump the pedal quickly to prevent lockup.
-
B.
Stab the pedal, release, and stab again.
-
C.
Shift to neutral before pressing the pedal.
-
D.
Apply firm, steady pressure and hold the pedal. Correct
The answer is "Apply firm, steady pressure and hold the pedal."
Anti-lock brakes handle the modulation for you, so a driver plants the pedal and holds it. Choice A tempts drivers who learned pumping as the general skid-braking answer for older cars and carry that technique over to a system the manual specifically tells them not to pump.
The traps in the wrong answers
A. Pump the pedal quickly to prevent lockup.
Pumping is the older technique for non-ABS brakes; the manual forbids it on ABS. This answer carries a pre-ABS pumping habit into a car the manual assumes has anti-lock brakes.
B. Stab the pedal, release, and stab again.
Stab-and-release is a form of pumping, which the manual rules out for ABS. This answer renames pumping as stabbing without changing what the pedal is doing.
C. Shift to neutral before pressing the pedal.
Neutral is not part of the ABS procedure the manual describes. This answer adds a manual-transmission step that has no place in the ABS instruction.
