Check Oil Light If the light comes on and you hear a chime or stays on after starting your vehicle, your engine oil level should be checked. Passlock Warning Light This light will come on briefly whenyou turn the ignition on. The light will stay on until the engine starts. CHECK OIL THEFT SYSTEM Prior to checking theoil level, be sure your vehicle has been shut off for several minutes and is on a level surface. Checkthe oil level on your dipstick and bring it to the proper level. See "Engine Oil"in the Index. NOTE: A false CHECK OIL light may be generated when parking on steep grades. The oil level monitoring system only checks oil level during the brief period between key on and engine crank. It does not monitor engine oil level when the engine is running. Additionally, an oil level check is only performed if the engine has been turnedoff for a considerable periodof time allowingthe oil normally in circulation to drain backinto the oil pan. If the light flashes for several seconds,the Passlock system has entered a tamper mode. If the vehicle fails to start, see "Passlock" in the Index. If the light comes on continuously while driving and stays on, there may be a problem with the Passlock system. Your vehicle will not be protected by Passlock, and you shouldsee your retailer.
