This warning light indicates the engine oil pressure is low.
If the warning light illuminates while driving:
1. Drive safely to the side of the road, park and turn the engine off.
2. Allow the vehicle to sit for five minutes, then check the engine oil level. If the level is low, add oil as required.
If the warning light remains on after adding oil or if oil is not available, call an authorized HYUNDAI dealer.
CAUTION
If the engine is not stopped immediately after the engine oil pressure warning light is illuminated, severe damage could result.
CAUTION
If the oil pressure warning light stays on while the engine is running, serious engine damage may result. The oil pressure warning light comes on whenever there is insufficient oil pressure. In normal operation, it should come on when the ignition switch is turned on, then go out when the engine is started.
