relative distance between the vehicle and an obstacle.
Warning indicators for the front area are located above
the center air outlets in the dashboard.
Warning indicators for the rear area are located in the
rear passenger compartment lamp.

segments light up, depending on the distance. An
intermittent acoustic warning will also sound as the

When the “ENGINE OIL LEVEL – CHECK LEVEL”
message appears while the engine is running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning will first come on
intermittently and then stay on if the oil level drops
further.
If no oil leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The engine oil level warnings should not be ignored.
