At R&R Auto Group in Schuylkill Haven, Pennsylvania, we know that your Chevrolet is equipped with advanced technology designed to keep you safe, efficient, and informed. One of the most important features of your vehicle’s safety system is the dashboard warning lights — those small but vital icons that appear on your instrument cluster to alert you of everything from system activations to potential maintenance concerns.
Knowing what these lights mean, and when to act, can make all the difference in preventing costly repairs and keeping your Chevrolet performing at its best.
The Color Code: Understanding the Urgency
Modern Chevrolet vehicles use color-coded warning lights to help you understand the level of attention a particular issue requires.
Red Warning Lights signal a critical issue that needs immediate attention. These often indicate safety or mechanical problems that could cause damage or compromise your ability to drive safely.
Yellow or Orange Warning Lights represent issues that require prompt service. They’re not emergencies but should never be ignored — these are early warnings that something needs attention soon.
Green or Blue Lights are generally informational, showing that a system is active, such as your cruise control, high beams, or turn signals. These lights confirm functionality, not faults.
Red Warning Lights: Stop and Check Immediately
When a red light appears, it’s time to pull over safely and evaluate the situation or contact the R&R Auto Group Service Department immediately.
Brake System Warning Light:
If this icon glows red, it can mean several things — the parking brake might still be engaged, brake fluid may be low, or there could be a more serious problem within the braking system. Driving with this light on can be dangerous, as it may reduce your stopping power.
Oil Pressure Warning Light:
This light, shaped like an oil can, warns that your engine oil pressure is dangerously low. Driving under these conditions can cause severe engine damage. Pull over immediately, shut off the engine, and check the oil level. If the level is normal, the issue could be a faulty sensor or a deeper oil pump concern — have it inspected right away.
Engine Temperature Warning Light:
This red thermometer symbol means your engine is overheating. Continuing to drive with an overheated engine risks permanent internal damage. Pull over, turn off the engine, and allow it to cool before checking coolant levels.
Battery Charge Warning Light:
Indicated by a battery symbol, this light shows a malfunction in your vehicle’s charging system. The issue could stem from the alternator, battery, or voltage regulator. If this light stays on, have your vehicle serviced immediately before it stalls or fails to restart.
Yellow or Orange Lights: Proceed with Caution
Yellow or orange lights are less urgent than red, but they still require prompt action. These alerts often indicate a system malfunction or maintenance issue that, if ignored, could become costly over time.
Check Engine Light (CEL):
The most familiar warning, the Check Engine Light, can signal a range of issues — from a loose gas cap to more serious problems like misfires, emission system failures, or sensor malfunctions. Even if your Chevrolet seems to run fine, it’s crucial to have this diagnosed by certified technicians at R&R Auto Group.
Tire Pressure Monitoring System (TPMS) Light:
This horseshoe-shaped icon with an exclamation point appears when one or more tires are underinflated. Driving on low tire pressure reduces fuel efficiency and increases the risk of a blowout. Inflate your tires to the recommended PSI and monitor the light. If it stays on, the system may need recalibration.
Traction Control or Stability Control Warning Light:
If this light illuminates while driving, your traction or stability system is actively working to maintain grip on slippery roads. However, if it stays on continuously, it could indicate a fault in the system — one that needs service to ensure your safety in poor weather conditions.
ABS Warning Light:
This light indicates an issue with your Anti-lock Braking System. While your standard brakes may still function, the ABS feature — which prevents wheel lockup during hard braking — may be disabled. This can affect control during emergency stops, making prompt inspection essential.
Green and Blue Lights: System Status Indicators
Green and blue lights generally signal that a particular system or feature is currently active, not that there’s a problem.
High Beam Indicator (Blue):
This icon appears whenever your high beam headlights are engaged. It’s a reminder to switch back to low beams when approaching oncoming traffic.
Cruise Control Indicator (Green):
When you set your cruise control, this light appears to confirm that the system is active and maintaining your set speed.
Turn Signal and Headlight Indicators:
Simple yet important, these lights show the activation of everyday systems — confirming that your Chevrolet’s essential features are operating as intended.
What to Do When a Warning Light Appears
When a warning light appears on your Chevrolet’s dashboard, the best course of action depends on the color and type of alert:
If it’s red, pull over safely and contact R&R Auto Group immediately. Continuing to drive could lead to major mechanical damage or safety risks.
If it’s yellow or orange, schedule a service appointment soon. These lights often point to issues that are easily fixed when caught early but can become expensive if ignored.
If it’s green or blue, no action is required — just be aware that the system is currently operating.
