Understanding the Color Codes: Green, Yellow, and Red VW Symbols

Volkswagen, like most manufacturers, uses a color-coded system for dashboard lights, similar to traffic signals, to quickly convey the urgency and nature of the message:

Green Lights: These are typically informational. Green Volkswagen Jetta symbols indicate that a system is active and functioning correctly. They are not warnings but rather confirmations.
Yellow Lights: Yellow Volkswagen Jetta symbols are caution lights. They suggest a potential issue that needs attention soon. While not immediately critical, yellow lights should prompt you to investigate and schedule a service check.
Red Lights: Red Volkswagen Jetta symbols signal serious problems requiring immediate action. When a red light appears, it often indicates a condition that could cause damage to your vehicle or compromise safety. It’s usually advised to safely stop the car and seek professional assistance.

Green Volkswagen Jetta Dashboard Symbols: Informational Lights

Green lights in your Volkswagen Jetta are purely for information, indicating systems in operation.

Daytime Running Lights: This green symbol indicates that your daytime running lights are activated, enhancing visibility during the day.
Shift Lock: This symbol confirms that the shift lock mechanism is engaged, preventing gear shifting without brake pedal application.

Yellow Volkswagen Jetta Dashboard Symbols: Caution and Warning Lights

Yellow dashboard lights in your VW Jetta signal potential issues that require timely attention. Address these promptly to prevent escalation into more significant problems.

ABS (Anti-lock Braking System): A yellow ABS symbol suggests a potential malfunction in your Jetta’s anti-lock braking system. While regular braking might still function, the ABS, crucial for preventing wheel lock-up during hard braking, may be compromised.
AdBlue Level Low: This light warns that your Jetta’s AdBlue (Diesel Exhaust Fluid) level is low. Refilling AdBlue is necessary for diesel models to reduce emissions.
AdBlue System Malfunction: Indicates a problem within the AdBlue system itself, requiring professional diagnosis and repair to maintain emission control.
Airbag System Fault: A serious warning indicating a malfunction in the airbag system. In the event of a collision, airbags may not deploy correctly. Immediate service is crucial.
Automatic Transmission Malfunction: Signals a potential issue within the automatic transmission system. This could range from minor sensor glitches to more significant mechanical problems.
Brake Light Bulb Failure: Indicates that one or more of your Jetta’s brake light bulbs has burned out, reducing visibility to drivers behind you and posing a safety risk.
Brake Pad Wear Indicator: This symbol alerts you that your Jetta’s brake pads are nearing the end of their lifespan and likely need replacement soon.
Bulb Failure: A solid yellow bulb symbol typically means a bulb is burned out. A blinking bulb symbol can indicate a headlight system issue, requiring further investigation.
Diesel Engine Pre-Glow: A solid light shows the diesel engine pre-glow system is active, especially during cold starts. A blinking light may point to a diesel engine malfunction.
Check Engine Light/Engine Malfunction: One of the more concerning yellow lights. It can indicate a wide array of engine-related issues, from minor sensor problems to more serious mechanical faults. A diagnostic check is essential.
Electric Power Control (EPC): Similar to the check engine light, the EPC light suggests potential engine management or electronic throttle control issues.
ESP/ASR (Electronic Stability Program/Anti-Slip Regulation): A solid light means ESP or Traction Control is deactivated. A blinking light indicates the system is actively intervening to maintain stability, often on slippery surfaces.
Particulate Filter (Diesel): Indicates a blockage in the diesel particulate filter, which can affect engine performance and emissions. Consult your owner’s manual for recommended actions, which may include driving at higher speeds to clear the filter.
Fuel Cap Loose or Missing: This symbol reminds you to check your fuel cap. A missing or improperly tightened fuel cap can cause fuel evaporation and trigger emission control warnings.
Hybrid Drive System Malfunction (Yellow): For Jetta hybrid models, this indicates a potential issue within the hybrid drive system, requiring a hybrid system specialist for diagnosis.
Immobilizer Active/Incorrect Key: The immobilizer symbol may light up if the system doesn’t recognize the key being used, possibly due to an incorrect key or a system malfunction.
License Plate Bulb Failure: Similar to brake light bulb failure, this indicates a burned-out license plate bulb, which is a legal requirement for vehicle visibility.
Low Fuel Level: A straightforward indicator that your Jetta is running low on fuel and you should refuel soon.
Oil Level Low: Indicates low engine oil. Check your oil level manually and top up if needed. If the light persists after topping up, there may be an oil leak or sensor issue.
Rain Sensor Malfunction: Suggests a problem with the rain sensor, which automatically controls your windshield wipers. If the light remains after restarting the car, service may be needed.
Steering System (Power Steering Reduced): A solid yellow steering wheel symbol indicates reduced power steering assist. Steering will become heavier, but the vehicle is still drivable with caution.
Tire Pressure Monitoring System (TPMS): Indicates low tire pressure in one or more tires. Check your tire pressures and inflate to the recommended levels. If the light persists, there may be a slow leak or TPMS malfunction.
Washer Fluid Low: A reminder that your windshield washer fluid is low and needs refilling for optimal windshield cleaning.

Red Volkswagen Jetta Dashboard Symbols: Critical Warning Lights

Red lights demand immediate attention. When a red symbol illuminates in your Volkswagen Jetta, safely stop the car and assess the situation or call for assistance.

AdBlue No Restart: A critical warning for diesel Jettas. It indicates a severe AdBlue system issue or critically low AdBlue, preventing engine restart after it’s turned off.
Alternator/Battery Charging Fault: A red battery symbol usually means the alternator is not charging the battery. Continued driving will drain the battery, potentially leading to the car stalling.
Coolant Level Low/Coolant Temperature High: A critical engine overheating warning. Low coolant level or high temperature can cause severe engine damage. Stop immediately and allow the engine to cool down. Do not drive until the issue is resolved.
DSG Transmission Temperature High: For Jetta models with DSG transmissions, this red light indicates the transmission is overheating. Stop the vehicle, shift to Park, and allow the transmission to cool down before proceeding.
Electric Parking Brake Fault: Indicates a malfunction with the electronic parking brake system. It may not engage or disengage properly.
Hood Open: A simple but important red light indicating that the hood (bonnet) is not properly closed. Stop and ensure it is securely latched.
Hybrid Drive System Malfunction (Red): A critical hybrid system fault in Jetta hybrid models. Stop the vehicle immediately as it indicates a severe issue with the hybrid powertrain.
Oil Pressure Low: One of the most critical red lights. It means the engine is losing oil pressure, which can cause immediate and severe engine damage. Stop the car immediately and turn off the engine. Do not restart until the issue is diagnosed and fixed.
Brake System Warning: A red brake system warning light can indicate several critical issues:
- Parking brake engaged.
- Low brake fluid level.
- Major ABS malfunction (often accompanied by a yellow ABS light).
  Any brake system warning requires immediate attention as it directly affects your ability to stop safely.
Steering System Malfunction: A blinking red steering wheel symbol signifies a serious steering system malfunction. Steering control may be severely compromised. Stop the vehicle immediately and do not drive further.
