3-20 Instruments and controls/Warning and indicator lights itoring system will not re-check tire inflation pressures until the vehicle is first driven to a vehicle speed of at least 20 mph (32 km/h). After adjust- ing the tire pressures, increase the vehicle speed to at least 20 mph (32 km/h) to start the TPMS re-checking of the tire inflation pressures. If the tire pressures are now above the severe low pressure threshold, the low tire pressure warning light should turn off a few minutes later. Therefore, be sure to install the specified size for the front and rear tires. & ABS warning light CAUTION . If any of the following conditions occur, we recommend that you have the ABS system repaired at the first available opportunity by your SUBARU dealer. – The warning light does not illuminate when the ignition switch is turned to the “ON” position. – The warning light illuminates when the ignition switch is turned to the “ON” position, but it does not turn off even after starting the vehicle. – The warning light illuminates while driving. . When the warning light is on (and the brake system warning light is off), the ABS function shuts down. However, the conventional brake system continues to oper- ate normally. The ABS warning light illuminates to- gether with the brake system warning light if the EBD system malfunctions. For further details of the EBD system mal- function warning, refer to “Brake system warning light” F3-20. NOTE If the warning light behavior is as described in the following conditions, the ABS system may be considered normal. . The warning light illuminates when the ignition switch is turned to the “ON” position and turns off approxi- mately 2 seconds after the engine has started. . The warning light illuminates right after the engine is started but turns off immediately, remaining off. . The warning light remains illumi- nated after the engine has been started, but it turns off while driving. . The warning light illuminates while driving, but it turns off immediately and remains off. When driving with an insufficient battery voltage such as when the engine is jump started, the ABS warning light may illumi- nate. This is due to the low battery voltage and does not indicate a malfunction. When the battery becomes fully charged, the light will turn off. & Brake system warning light WARNING . Driving with the brake system warning light on is dangerous. This indicates your brake system may not be working properly. If the light remains illuminated, have the brakes inspected by a SUBARU dealer immediately. . If at all in doubt about whether the brakes are operating prop- erly, do not drive the vehicle. Have your vehicle towed to the nearest SUBARU dealer for re- pair.
