Instead, the "oil lamp" (likely the low oil pressure warning light) only comes on when there's a problem detected with the oil pressure. If this light comes on, do not continue driving. This indicates a serious issue with your engine's lubrication system and could cause catastrophic engine damage.
If the light is on, here's what you should do:
1. Check the oil level immediately. Use the dipstick to check if the oil is low. If it is, add the correct type and amount of oil (check your owner's manual).
2. If the oil level is fine and the light remains on, get your vehicle towed to a qualified mechanic immediately. This indicates a more serious problem, such as a failing oil pump, a hole in the engine block, or a sensor malfunction. Driving with the low oil pressure light on will likely result in significant engine damage.
There's no "reset" for a low oil pressure warning; you need to address the underlying mechanical issue. Don't confuse this with an oil change reminder light (if your Escalade even has one – it’s unlikely for that year); those are usually reset by a mechanic during an oil change service.
