'06 HIGHLANDER_U (L/O 0508) (d) Charging System Warning Light This warning light comes on when the ignition switch is turned to the "ON" position, and goes off when the engine is started. When there are problems in the charging system while the engine is running, the warning light comes on. (e) Low Engine Oil Pressure Warning Light This light warns that the engine oil pressure is too low. If it flickers or stays on while you are driving, pull off the road to a safe place and stop the engine immediately. Call a Toyota dealer or qualified repair shop for assistance. The light may occasionally flicker when the engine is idling or it may come on briefly after a hard stop. There is no cause for concern if it then goes out when the engine is accelerated slightly. The light may come on when the oil level is extremely low. It is not designed to indicate low oil level, and the oil level must be checked using the level dipstick. (f) Malfunction Indicator Lamp This lamp comes on when the ignition key is turned to the "ON" position and goes off after the engine starts. This means that the warning light system is operating properly. If the lamp remains on, or the lamp comes on while driving, first check the followings. NOTICE When the charging system warning light comes on while the engine is running, malfunctions such as the engine drive belt being broken may have occurred. If the warning light comes on, immediately stop the vehicle in a safe place and contact your Toyota dealer. D Empty fuel tank If the fuel tank is empty, refuel immediately. D Loose fuel tank cap If the fuel tank cap is loose, securely tighten it. These cases are temporary malfunctions. The malfunction indicator lamp will go off after taking several driving trips. If the lamp does not go off even after several trips, contact your Toyota dealer as soon as possible. NOTICE Do not drive the vehicle with the warning light on-even for one block. It may ruin the engine. 137
