The Importance of Dashboard Warning Lights

Modern vehicles, including the Ford Ranger, are equipped with numerous sensors and computerized systems that constantly monitor various aspects of the vehicle’s performance. When these systems detect an issue, they illuminate specific warning lights on the dashboard to alert the driver. These lights serve as an early warning system, allowing you to address potential problems before they escalate into more serious and costly repairs.

Ford uses a colour-coded system for its dashboard symbols, making it easier for drivers to gauge the urgency of the warning:

• Green: Indicates that a system is active or functioning correctly.
• Yellow/Amber: Indicates that something is not functioning correctly and requires attention soon.
• Red: Signals a serious problem that requires immediate action.

Understanding this colour system can help you quickly assess the severity of any warning light that appears on your dashboard.

Key Engine Warning Lights to Watch For
