STARTING AND DRIVING When the "VSC/TRAC" warning light and "VSC OFF" indicator light come on, the vehicle skid control system is not operating, but there is no problem if you continue to drive. In the following cases, contact your Lexus dealer: D The "VSC/TRAC" warning light, "VSC OFF" indicator light and slip indicator light do not come on after the ignition is turned to on. D The "VSC/TRAC" warning light and "VSC OFF" indicator light remain on after the ignition is turned to on. D The "VSC OFF" indicator light comes on while driving without pushing the center differential lock switch. D Only use tires of specified size. The size, manufacturer, brand and tread pattern for all 4 tires should be the same. If you use the tires other than specified, or different type or size, the vehicle skid control system may not function correctly. When replacing the tires or wheels, contact your Lexus dealer. (See "Checking and replacing tires" on page 313.) CAUTION D Active traction control system, vehicle skid control system and anti-lock brake system are electronic systems designed to help the driver maintain control under adverse conditions. They are not a substitute for safe driving practices. Factors including speed, road conditions and driver steering input can all affect whether active traction control system, vehicle skid control system and anti-lock brake system will be effective in preventing a loss of control. Always keep safety driving in mind. If the slip indicator light flashes, sounding an alarm, special care should be taken while driving. 229
