Starting and operating NOTE If the warning light behavior is as described below, the ABS system may be considered normal. D The warning light comes on right after the engine is started but goes out immediately, remaining off. D The warning light remains on after the engine has been started, but it goes out when the vehicle speed reaches about 8 mph (12 km/h). D The warning light comes on during driving, but it goes out immediately and remains off. When driving with an insufficient battery voltage such as when the engine is jump started, the ABS warning light may come on. This is due to the low battery voltage and does not indicate a malfunction. When the battery becomes fully charged, the light will go out. VDC (Vehicle Dynamics Control) system (if equipped) WARNING Always use the utmost care in driving - overconfidence because you are driving with a VDC system equipped vehicle could easily lead to a serious accident. D Even if your vehicle is equipped with VDC, winter tires or snow chains should be used when driving on snow-covered or icy roads; in addition, vehicle speed should be reduced considerably. Simply having a VDC system does not guarantee that the vehicle will be able to avoid accidents in any situation. D Activation of the VDC system is an indication that the road being travelled on has a slippery surface; since having VDC is no guarantee that full vehicle control will be maintained at all times and under all conditions, its activation should be seen as a sign that the speed of the vehicle should be reduced considerably. - CONTINUED - CAUTION 7-25
