Warning and Indicator Lights
& Engine Low Oil Level Warning Light s03ae58
This light illuminates when the engine oil level decreases to the lower limit.
If the warning light illuminates, check the engine oil level on a level surface. When the engine oil level is not within the normal range, refill with engine oil. Refer to“ Engine Oil” FP424. After adding or changing the engine oil, warm up the engine and stop it on a level surface, then start the engine after a lapse of 1 minute or more. Confirm that the warning light has turned off after the engine has started. If the warning light does not turn off after refilling the engine oil, or the light illuminates even though the engine oil level is within the normal range, have the vehicle checked by a SUBARU dealer.
NOTE
. The oil level will be detected by the system just after turning the ignition switch to the“ OFF” position. If the oil level is below the lower limit when the ignition switch is turned to the“ ON” position, the engine low oil level warning light will turn on.
. When the vehicle is parked on a steep slope, the engine low oil level warning light may not illuminate even if the oil level is below the
lower limit to avoid erroneous lighting.
& AT OIL TEMP Warning Light( CVT Models) s03ae07
If this light illuminates when the engine is running, it may indicate that the transmission fluid temperature is too hot.
If the light illuminates while driving, immediately stop the vehicle in a safe place and let the engine idle until the warning light turns off.
! Transmission control system warning s03ae0701
If the“ AT OIL TEMP” warning light flashes after the engine has started, it may indicate that the transmission control system is not working properly. Contact your nearest SUBARU dealer for service immediately.
& Low Tire Pressure Warning Light( U. S.- Spec. Models) s03ae08
When the ignition switch is turned to the“ ON” position, the low tire pressure warning light will illuminate 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 tire 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 underinflated. 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.
