Starting and operating B Brake booster The brake booster uses engine manifold vacuum to assist braking force. Do not turn off the engine while driving because that will turn off the brake booster, resulting in poor braking power. The brakes will continue to work even when the brake booster completely stops functioning. If this happens, however, you will have to push the pedal much harder than normal and the braking distance will increase. J Disc brake pad wear warning indicators OM-H0163 The disc brake pad wear warning indicators on the disc brakes give a warning noise when the brake pads are worn. If a squeaking or scraping noise is heard from the disc brakes while braking, immediately have your vehicle checked by your SUBARU dealer. ABS (Anti-Lock Brake System) WARNING Always use the utmost care in driving - overconfidence because you are driving with an ABS equipped vehicle could easily lead to a serious accident. - CONTINUED - 7-23
