Chevrolet Dashboard Lights Explained

Your 2025 Chevrolet Trailblazer’s dashboard is more than just a display—it’s your vehicle’s way of communicating important information about its systems and your safety. From reminders to warnings, these lights ensure you stay informed while on the road. Understanding what these symbols mean can help you maintain your vehicle’s performance and safety. Below, we’ll break down the key dashboard lights and what they tell you.

Seat Belt and Airbag Warning Lights

Driver Seat Belt Reminder

This light activates when you start the vehicle, and your seat belt is unbuckled. It will flash initially and remain lit until you buckle up. The Trailblazer also features reminders for front and rear passengers, ensuring everyone stays safe.

Airbag Readiness Light

When you turn on your vehicle, this light will flash briefly to indicate the system is functioning. If it stays on, there’s a problem with the airbag system that requires immediate service. Additionally, a separate warning light monitors the status of the front passenger airbag, ensuring it’s ready to deploy when needed.

Safety and Driver Assistance Warning Lights

The following features will only appear if your vehicle is equipped with them.

Lane Keep Assist (LKA) Icon

When equipped with LKA, this light shows the system’s status. A white light means the system is inactive, green indicates it’s actively helping you stay in your lane, and orange/amber signals that you may have unintentionally crossed a lane line.

Lane Departure Warning (LDW) Icon

This icon lights up green when the system is active. If it flashes orange/amber, it means you’ve crossed a detected lane line without signaling.

Automatic Emergency Braking (AEB) Disabled Light

If AEB or Enhanced AEB is set to “Alert Only” or “Off,” this light appears to remind you that automatic braking is disabled.

Forward Collision Alert Vehicle Ahead Indicator

A green light means the system detects a vehicle ahead, while an orange/amber light warns you may be following too closely.

Cruise Control and Adaptive Cruise Control (ACC) Lights

A white cruise control icon indicates the system is on but not set, while green means a speed has been set. For ACC, white means the system is on, but no following gap is set, and green means it's actively maintaining a gap.

Braking, Accelerating, and Steering Warning Lights

Brake System Warning Light

This light flashes briefly when you start your vehicle. If it stays on, there may be an issue with the brakes, such as low brake fluid.

Hill Descent Control Light

If your Trailblazer has this feature, the light will flash when it’s engaged. A blinking light indicates the system is actively controlling your speed on a hill.

Traction Control System/Electronic Stability Control (TCS/ESC) Light

This light flashes when the system is actively working to improve traction or stability.

Tire Pressure Light

If your vehicle has a Tire Pressure Monitor System, this light flashes briefly at startup. If it stays on, it indicates low tire pressure.

Engine and Battery Warning Lights

Check Engine Light (Malfunction Indicator Lamp)

This light signals an issue with your engine or propulsion system. For EVs, it may indicate a charging problem.

Engine Oil Pressure Light

This light activates when the engine is off, but the vehicle is on. If it stays lit while driving, it may indicate low oil pressure.

Charging System and Battery Fault Lights

A persistent charging system light signals an electrical system issue, while the battery fault light indicates a problem with the high-voltage battery in EV models.

Service Vehicle Soon/Propulsion System Failure Light

This warning means your EV has detected a potential battery issue and power consumption will be reduced to protect the system.

Headlamp Warning Lights

High-beam Light Icon

This light activates when you switch from low to high beams by pushing the turn signal lever away from you.

Adaptive Forward Lighting Light

If your Trailblazer is equipped with Adaptive Forward Lighting, this light warns of system malfunctions.

Lamps On Reminder Light

This light appears when your exterior lamps, including headlights and taillights, are on.

Front Fog Lamp Light

This icon illuminates when your fog lamps are on. Note that fog lamps automatically turn off when high beams are engaged.
