The Reason the Engine Oil Light Comes On

Model: (Various brands) Various
Part: Service warning light

Video tutorial

In this video, you will see why the engine oil light comes on: the reason is insufficient oil pressure in the lubrication system. When you start the vehicle, the light comes on because the engine is not yet running, so the system is not under pressure.

It should turn off as soon as the engine starts. If it comes on while you are driving, it is a serious warning because a lack of pressure in the circuit can cause severe damage to the engine.

There may be a significant leak in the circuit, problems with the oil pump, or issues with the pressure sensor. If the light is flashing, it indicates the need for an oil change.

You do not need to stop but should arrange for the change as soon as possible.

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
