Your oil light might come on at start up when the car is in idle. It should however, go off when the engine has built enough pressure.
If the light comes on when you are driving then you need to pull over and switch the engine off.
You should check the level of the oil by using a dipstick (look for a yellow handle with the word OIL on it). Pull the dipstick out and wipe it off using a clean cloth. Reinsert the dipstick and pull it out again.
Check the reading to see if the oil level is below the marked line on the dipstick. If it is low, you need to top up the oil. This should solve the problem.
If the oil level seems to be fine then the problem lies with the oil pump.
You can solve the problem of low oil level by topping up the oil in the oil sump otherwise, you should have your car towed to a mechanic.
Do not attempt to drive it any further until you know exactly what is wrong.
If you don’t have a dipstick and some do not, you must contact an ASE Certified mechanic, dealership or repair shop to investigate further.
