3-14 Instruments and controls & Rear differential oil CAUTION temperature warning light . The rear differential oil will deteriorate if its temperature increases enough for the rear differential oil temperature warning light to come on. It is advisable to have the rear differential oil replaced as soon as possible. Reduce vehicle speed and park the vehicle in a safe place as soon as possible if the R.DIFF TEMP light comes on. Continued driving with this light on can damage the rear differential and other parts of the powertrain. If this light comes on when the engine is running, it may indicate that the rear differential oil temperature is too hot. If the light comes on while driving, reduce vehicle speed and stop the vehicle at the nearest safe place. Park the vehicle for several minutes. After the light goes out, you can start driving. If the light does not go out, contact the nearest SUBARU dealer for service. & Low tire pressure warning light When the ignition switch is turned to the "ON" position, the low tire pressure warning light will come on for approximately 2 seconds to check that the tire pressure monitoring system (TPMS) is functioning properly. If there is no problem and all tires are properly inflated, the light will go out. Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper inflation pressure for those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under- NOTE . If the tire pressures are not correct and/or the tires are not all the same size and brand, the rear differential will be heavily loaded when the vehicle is driven, resulting in an abnormally high oil temperature. inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
