  1. What is the recommended action if your vehicle begins to overheat while driving?

    Answer: Turn on the heater and pull over safely

    Turning on the heater draws heat away from the engine, and pulling over safely prevents further damage from continued driving.

  2. What does 'tire rotation' accomplish?

    Answer: Moves tires to different positions to even out wear

    Tire rotation moves tires between axle positions to equalize tread wear, extending the life of all four tires.

  3. What is the function of the vehicle's serpentine belt?

    Answer: Drives multiple accessories like the alternator, power steering pump, and AC compressor

    The serpentine belt drives multiple engine accessories simultaneously, including the alternator, power steering pump, and air conditioning compressor.

  4. How do you know when your vehicle's coolant needs to be flushed?

    Answer: According to manufacturer schedule, typically every 30,000–50,000 miles

    Manufacturers typically recommend flushing coolant every 30,000–50,000 miles as it degrades over time, losing its anti-corrosion and freezing-point-depression properties.

  5. What happens if you drive with a broken or missing gas cap?

    Answer: Fuel evaporates and the check engine light may illuminate

    A missing gas cap allows fuel vapors to escape the tank, reducing fuel efficiency and often triggering the check engine light due to EVAP system failure.

  6. At what tread depth should tires be replaced for safety?

    Answer: 2/32 of an inch (the legal minimum)

    Tires must be replaced when tread depth reaches 2/32 of an inch, which is the legal minimum and the point where wet-road traction becomes dangerously compromised.

  7. What does the 'P' position on an automatic transmission gear selector do?

    Answer: Prevents the vehicle from rolling by locking the drivetrain

    Park (P) locks the output shaft of the transmission, preventing the vehicle from rolling, but should always be used with the parking brake.
