Common questions
Why did several warning lights come on at once?
A weak battery, wheel-speed sensor fault, or communication problem can trigger several systems. Read the stored codes before replacing random parts.
Can I drive with a yellow warning light?
Often yes, but it depends on the symbol. Drive gently and schedule a check if the light stays on, flashes, or the car feels different.
Which warning lights mean stop now?
Oil pressure, coolant temperature, brake, charging, and flashing check-engine lights should be treated as stop-safely warnings.
