Meaning
This light means a sensor has measured the engine oil LEVEL as below its minimum. It is a different warning from the red oil pressure light, which indicates the engine is not maintaining oil pressure right now, and from the oil change reminder, which is only a service interval.

Can I drive?
Drive with caution
Check and correct the level before driving further; running an engine low on oil causes wear that does not reverse, and a genuinely low level can progress to a loss of oil pressure.

Editorial review
If this light appears with brake, steering, airbag, overheating, oil pressure, fuel, smoke, or fire symptoms, treat it as safety-critical.
Short answer
This light means a sensor has measured the engine oil LEVEL as below its minimum. It is a different warning from the red oil pressure light, which indicates the engine is not maintaining oil pressure right now, and from the oil change reminder, which is only a service interval.

Key takeaways
Low level and low pressure are different warnings with very different urgency.
Correct the level before driving further, and find out where the oil went.

Engine oil level low light
This light means a sensor has measured the engine oil LEVEL as below its minimum. It is a different warning from the red oil pressure light, which indicates the engine is not maintaining oil pressure right now, and from the oil change reminder, which is only a service interval.
Common triggers
Oil consumed between services faster than expected
An oil leak losing oil externally
An underfill at the last oil change
A faulty oil level sensor reading low incorrectly
What to check
Park on level ground, let the engine sit for several minutes, then check the dipstick or the electronic reading
Top up with the correct oil specification to the full mark — do not overfill
Look under the vehicle and around the engine for leak evidence
If the level is correct but the light persists, have the level sensor checked

Frequently asked questions
Is this the same as the red oil pressure light?
No, and the difference matters. A low LEVEL warning gives you time to check and top up. A red oil PRESSURE warning means stop the engine now — pressure has already been lost.
How much oil should I add?
Add a small amount at a time and re-check. Overfilling is its own problem: it can aerate the oil and damage seals.
