1999 Subaru Forester Owner's Manual - Page 240

Starting and operating OM-H2791 D If the ABS warning light illuminates while the vehicle is in motion, stop towing the trailer and have repairs carried out immediately by the nearest SUBARU dealer. B Driving on grades D Before going down a steep hill, slow down and shift into low gear in order to utilize the engine braking effect and prevent overheating of your vehicle's brakes. Do not make sudden downshifts. D When driving uphill in hot weather, the air conditioner may turn off automatically to protect the engine from overheating. D When driving uphill in hot weather, pay attention to the water temperature gauge needle (for all vehicles) and ATF OIL TEMP warning light (for AT vehicles) since the engine and transmission are relatively prone to overheating under these conditions. If the water temperature gauge needle approaches the OVERHEAT zone or the ATF OIL TEMP warning light illuminates, immediately switch off the air conditioner and stop the vehicle at the nearest safe place. Refer to Engine Overheat section (chapter 8), and Warning and Indicator Lights section (chapter 3) in the owner's manual. D If your vehicle has a automatic transmission, avoid using the accelerator pedal to stay stationary on an uphill slope instead of using the parking brake or foot brake. This may cause the transmission fluid to overheat. Also, if your vehicle is equipped with an automatic transmission, avoid driving with the gear selector lever in "D" when towing a heavy trailer to prevent fluid overheating. - CONTINUED - 7-55
