Question 3872
How does the ISA system (intelligent speed assistance) work?
- It detects that the inflation pressure of a tire is incorrect.
- It helps detect an obstacle by applying emergency braking.
- It helps maintain speed through specific and appropriate information.
Show answer and explanation
Correct answer: It helps maintain speed through specific and appropriate information.
ISA tells you the speed limit for the stretch of road you’re driving on and helps you stay within it. It gets the limit from signs or navigation maps and shows it on the instrument panel, like the 80 sign shown on the instrument panel in the image. If you exceed it, it warns you or reduces power, but you can always press the accelerator harder. Braking for an obstacle is AEB’s job, and monitoring tire pressure is TPMS’s job.
