CallWarning Light Guide
A dashboard light is the vehicle’s way of asking for attention, but not every light means the same level of urgency. The safest next step depends on which light is on, whether it is flashing, and what the vehicle is doing at the same time.
Oil pressure, temperature, brake system, and charging-system warnings should be treated as urgent. If the oil pressure light or temperature warning comes on, pull over safely, shut the engine down, and avoid driving until the cause is checked.
A steady check engine light may allow cautious driving to a shop if the vehicle feels normal. A flashing check engine light can point to a misfire that may damage the catalytic converter, so it should be inspected quickly and driven as little as possible.
A brake warning light can mean the parking brake is on, brake fluid is low, or a system fault needs attention. ABS and traction lights can affect how the vehicle behaves during hard braking or slippery conditions even if normal braking still feels okay.
Diesel trucks may show glow plug, DEF, emissions, water-in-fuel, fuel filter, or power-reduction warnings. Some warnings can place the truck into reduced power or no-start conditions if the problem is ignored.
If the light is steady and the vehicle feels normal, short cautious driving may be possible. If the light is flashing, the engine runs rough, power drops, or another warning appears, stop driving and request diagnostics.
Oil pressure, engine temperature, brake system warnings, severe charging warnings, and any flashing warning paired with rough running or smoke should be treated as urgent.
No. Codes identify the system or condition being reported. Testing is still needed before replacing parts.
Send the year, make, model, mileage, which light is on, whether it flashes, when it appeared, and any noises, smells, leaks, overheating, or drivability changes.
