Engine temperature warning
Driver guidance · STOP — symbol color, meaning and urgency can differ by vehicle
What the symbol may mean
High coolant temperature can signal overheating and imminent engine damage.
What to do now
Pull over safely, turn off the engine and allow it to cool. Never remove a hot radiator cap.
What a technician may check
Cooling system level, leaks, fans and thermostat need diagnosis after cooling.
Always follow the exact vehicle handbook; colored lamps and warning behavior vary across models. A serious vehicle fault should not be cleared or driven through without inspection.
