Understanding dashboard warning lights in your Vauxhall Corsa is essential for keeping you safe on the road, as they alert you to potential issues that could lead to accidents or breakdowns.
Ignoring them might result in costly repairs or unsafe driving conditions, so knowing what each one means helps with timely maintenance and prevents minor problems from becoming major ones. Always check your owner’s manual for model-specific details, and consult a mechanic if a light persists.
Quick Navigation
Red Warning Lights (Stop Immediately)
These lights indicate serious problems that require you to stop driving right away to avoid danger or damage.

Signals low oil pressure, which can cause engine damage from lack of lubrication or overheating. Pull over safely, turn off the engine, check oil level, and add if needed; do not drive until fixed.
Brake System Alert
Indicates issues like low brake fluid or a fault in the braking system, risking reduced stopping power. Stop immediately, check fluid levels, and seek professional help before driving again.
Battery Charge
Shows a problem with the battery or charging system, possibly due to a failing alternator. Stop the vehicle, inspect connections, and get it towed if it won’t start to prevent stranding.
Coolant Temperature
