The coolant light in a 1994 Lexus LS 400 may illuminate for several reasons, primarily indicating low coolant levels in the reservoir. It can also signal overheating due to issues like a malfunctioning thermostat, a failing water pump, or a leak in the cooling system. It's essential to check the coolant level and inspect for any leaks or mechanical failures to prevent engine damage. If the issue persists, consulting a mechanic is advisable.

It is possible that a check engine light on a Toyota Highlander will come on if the coolant level is low. Usually, though, there is another light that will come on that says 'low coolant' on some older Toyota's.
