With that warning, it is most likely you have too much oil in the motor. To check this you access the oil level through the dash display. The procedures to read the display are in the operator's manual. The oil is supposed to be measured at approximately 100 degrees C. If in deed it is too high, you will have to have it sucked out through a tube at the right rear of the motor or remove the drain plug and try to guess the right amount to drain, but this exposes you to the risk of being burned by the hot oil. This vehicle may not be equipped with a traditional dipstick. If you just had teh vehicle serviced and this display came on, then you should have the shop that did the work correct the level.
YOU DO NOT GUESS THE RIGHT AMOUNT!!! YOU PUT 100% FULL SYNTHETIC MOBILE ONE OIL IN. FIRST-YOU TURN THE KEY TO THE FIRST POSITION,SO ALL DASH LIGHTS ILLUMINATE,SECOND-ON THE LEFT HAND SIDE OF THE STEERING WHEEL YOU SCROLL THROUGH THE INFORMATION SYSTEM UNTIL YOU REACH OUTSIDE TEMP OF THE VEHICLE.THIRD-YOU PRESS THE ARROW UP BUTTON ON THE LEFT HAND SIDE OF THE STEERING WHEEL. IT WILL PROMPT YOU TO MAKE SURE THE CAR IS LEVEL. THEN TURN THE KEY TO THE SECOND POSITION(DO NOT START IT)AND IT WILL THEN TAKE ABOUT 5 SEC. TO READ AND CALCULATE HOW MANY QUARTS OF OIL YOU HAVE OR NEED. MINE JUS NEEDED 1.5 QUARTS :) THATS WHY I KNOW.
