Show answer & explanation

Correct answer: C. Schedule a diagnostic check with a mechanic as soon as possible.

The 'Check Engine' light indicates a problem detected by the vehicle's onboard diagnostic system. While it might not always signify an immediate breakdown, it's crucial to have it diagnosed by a mechanic to prevent potential damage, identify emissions issues, or address safety concerns.

Why the other options are wrong

  • A. While checking oil is part of general maintenance, the 'Check Engine' light can indicate many issues beyond just oil level; pulling over immediately isn't always necessary unless other symptoms are present.
  • B. Ignoring the light is unsafe and can lead to more significant, costly repairs or emissions test failure in the future.
  • D. Continuing to drive without understanding the issue could worsen the problem or lead to a breakdown, especially if the light is flashing.
