06 09.07 When the anti −lock brake system is activated, the following conditions may occur. They do not indicate a malfunction of the system: CAUTION Do not overestimate the anti −lock brake system: Although the anti −lock brake system assists in providing vehicle control, it is still important to drive with all due care and maintain a moderate speed and safe distance from the vehicle in front of you, because there are limits to the vehicle stability and effectiveness of steering wheel operation even with the anti− lock brake system on. If tire grip performance exceeds its capability, or if hydroplaning occurs during high speed driving in the rain, the anti −lock brake system does not provide vehicle control. D You may hear the anti−lock brake system operating and feel the brake pedal pulsating and the vibrations of the vehicle body and steering wheel. You may also hear the motor sound in the engine compartment even after the vehicle is stopped. Anti −lock brake system is not designed to shorten the stopping distance: Always drive at a moderate speed and maintain a safe distance from the vehicle in front of you. Compared with vehicles without an anti −lock brake system, your vehicle may require a longer stopping distance in the following cases: D Driving on rough, gravel or snow− covered roads. D At the end of the anti−lock brake system activation, the brake pedal may move a little forward. D Driving with tire chains installed. D Driving over the steps such as the joints on the road. D Driving on roads where the road surface is pitted or has other differences in surface height. Install all 4 tire of specified size at appropriate pressure: The anti −lock brake system detects vehicle speeds using the speed sensors for respective wheels' turning speeds. The use of tires other than specified may fail to detect the accurate turning speed resulting in a longer stopping distance. 2007 YARIS SEDAN from Oct. '06 Prod. (OM52736U) 177
