  1. You are adjusting the driver’s head restraint. Where should its center be?

    Correct answer: At about the center of the back of your head.

    Position the head restraint to support the back of the head. A low setting behind the neck does not provide the intended protection.

  2. Your car has driver-assistance features. What must you still be prepared to do?

    Correct answer: Control the vehicle yourself if a feature fails or is unavailable.

    Assistance technology does not replace the driver. Understand its limits and remain ready to operate the vehicle safely without it.

  3. Your vehicle has forward-collision warning but no automatic emergency braking. An alert sounds. What should you do?

    Correct answer: Assess the hazard and take the necessary braking or avoidance action.

    A warning-only system alerts the driver; it does not itself brake the vehicle. Know which functions your own vehicle actually provides.

  4. Mud or snow covers a sensor used by your assistance system. What should you do?

    Correct answer: Clean it as directed and do not rely on the system to detect every hazard.

    Obstructed sensors can limit assistance features. Follow the owner’s instructions and keep checking the surroundings yourself.
