Dashboard warning lights are a crucial part of modern vehicles, designed to alert drivers about potential issues or system activations. These symbols serve as an essential communication tool between the driver and the vehicle, ensuring that small issues are addressed before they turn into major problems.
Each car brand has its unique set of dashboard lights, but most follow a universal color scheme:
- Red Lights – Indicate urgent issues or potential safety hazards that require immediate attention.
- Yellow/Amber Lights – Serve as warnings for issues that need checking but do not necessarily require stopping the vehicle immediately.
- Green/Blue Lights – Inform the driver that a system is operating correctly, such as cruise control or high beams.
This guide explores the dashboard warning lights for Jeep, Subaru, and Volkswagen (VW) vehicles, helping drivers understand what each symbol means and how to respond to them.
Jeep Dashboard Symbols and Their Meanings
Jeep vehicles come with a variety of dashboard indicators designed to help drivers maintain safety and performance. Recognizing these symbols can prevent potential mechanical issues and keep the vehicle in optimal condition.
1. Engine Temperature Warning Light
Symbol: A thermometer submerged in liquid.
Meaning: This light indicates that the engine is overheating. Driving with an overheated engine can cause severe damage, including a blown head gasket or a cracked engine block. If this light appears, the driver should pull over safely, turn off the engine, and allow it to cool down before checking coolant levels. If coolant levels are low, topping them up may resolve the issue. However, if the light persists, professional assistance is required.
2. Battery Charge Warning Light
Symbol: A battery with positive and negative terminals.
Meaning: This light signals an issue with the vehicle’s charging system. A failing alternator, a weak battery, or damaged electrical wiring could be the cause. If this light appears, the driver should avoid using electrical components such as headlights, air conditioning, or the radio to conserve battery power and seek professional assistance as soon as possible.
3. Oil Pressure Warning Light
Symbol: An oil can drip liquid.
Meaning: This warning light indicates low oil pressure, which can lead to severe engine damage if left unchecked. Drivers should immediately pull over, turn off the engine, and check the oil level. If the level is low, adding oil might resolve the issue. However, if the light remains on despite adequate oil levels, it could indicate an oil pump failure or a clogged filter, requiring professional inspection.
Subaru Dashboard Symbols and Their Meanings
Subaru vehicles include several dashboard indicators that help drivers maintain their vehicle’s safety and performance. Many of these symbols relate to Subaru’s signature all-wheel-drive system and advanced safety features.
1. AT Oil Temperature Warning Light
Symbol: The words “AT OIL TEMP” displayed in capital letters.
Meaning: This warning light indicates that the automatic transmission fluid has exceeded the normal operating temperature. Overheating transmission fluid can lead to gear slippage, increased wear, and long-term damage. If this light appears, the driver should pull over, allow the transmission to cool, and check fluid levels if possible. Continuing to drive with an overheated transmission can result in costly repairs.
2. Vehicle Dynamics Control (VDC) Warning Light
Symbol: A car with skid marks behind it.
Meaning: This light signifies that Subaru’s Vehicle Dynamics Control system, which helps maintain stability by adjusting power and braking, has been deactivated or is malfunctioning. While the vehicle remains drivable, reduced traction control could make it harder to handle in slippery conditions. If the light stays on continuously, a professional inspection is recommended.
3. Brake System Warning Light
Symbol: An exclamation mark inside a circle, enclosed by parentheses.
Meaning: This light suggests an issue with the braking system, such as low brake fluid, worn brake pads, or a potential brake system failure. If the light appears while driving, the driver should pull over and inspect the brake fluid level. If the brake pedal feels soft or unresponsive, professional assistance is necessary to ensure safety.
Volkswagen (VW) Dashboard Symbols and Their Meanings
Volkswagen vehicles come equipped with a range of dashboard warning lights designed to provide drivers with critical system information. These indicators are especially important in diesel-powered VW models, which feature additional emissions-related warnings.
1. AdBlue Warning Light
Symbol: A light bulb with a droplet inside.
Meaning: This warning light is specific to diesel Volkswagen models. It indicates that the AdBlue fluid level is low. AdBlue is a liquid solution that reduces nitrogen oxide emissions in diesel engines. If the AdBlue level is too low, the vehicle may not start. Refilling the AdBlue tank promptly is essential to maintain compliance with emissions regulations.
2. Diesel Particulate Filter (DPF) Warning Light
Symbol: A rectangle with dots inside.
Meaning: This symbol warns that the diesel particulate filter (DPF) is clogged. The DPF captures and burns soot from the exhaust gases, preventing harmful emissions from being released into the air. When this light appears, driving at a higher speed (above 40 mph) for around 15 minutes may help burn off the excess soot and clear the filter. If the light remains on, professional cleaning or replacement may be necessary.
3. Tire Pressure Monitoring System (TPMS) Light
Symbol: An exclamation mark inside a flat tire icon.
Meaning: This light indicates that one or more tires have low pressure. Driving with underinflated tires can reduce fuel efficiency, affect handling, and increase the risk of a blowout. Drivers should check tire pressure as soon as possible and inflate the tires to the recommended PSI. If the light stays on after refilling, a sensor malfunction or a slow leak could be the cause.
Conclusion
Understanding dashboard symbols is essential for vehicle safety and performance. Whether driving a Jeep, Subaru, or Volkswagen, recognizing these warning lights allows drivers to take immediate action, preventing breakdowns and costly repairs.
For Jeep owners, paying attention to the Engine Temperature Warning, Battery Charge Warning, and Oil Pressure Warning lights is crucial to avoid serious mechanical failures.
Subaru drivers should be especially mindful of the AT Oil Temperature, Vehicle Dynamics Control, and Brake System warning lights to ensure their vehicle remains safe in all driving conditions.
Volkswagen owners, particularly those with diesel models, should pay close attention to the AdBlue Warning, Diesel Particulate Filter Warning, and Tire Pressure Monitoring System lights to maintain efficiency and emissions compliance.
By responding promptly to dashboard warning lights and following regular maintenance schedules, drivers can ensure their vehicles remain in peak condition while staying safe on the road.
