GAUGES, METERS AND SERVICE REMINDER INDICATORS (n) Vehicle Stability Control System Warning Lights These lights warn that there is a problem somewhere in the vehicle stability control system or traction control system. If the "VSC" warning light and "VSC OFF" indicator light come on, have your vehicle checked by Lexus dealer as soon as possible. The lights will come on when the ignition switch is turned to "ON", and will go off after about a few seconds. The lights may stay on for 60 seconds after the ignition switch is turned to the "ON" position. It is normal if they go out after a while. Depressing the brake pedal repeatedly may turn on the lights. It is normal if they go out after a few seconds. If the "VSC" warning light and "VSC OFF" indicator light come on, the vehicle stability control system does not activate, however, it is no problem to continue your driving. (o) Low Tire Pressure Warning Light and Chimes This light and chimes warn you that the tire inflation pressure is low. This light comes on when the ignition switch is turned to the "ON" position and goes off after a few seconds. This means the low tire pressure warning light is operating properly. If the warning light does not go off, or comes on or blinks during driving, or the chimes sound, this indicates that tire inflation pressure is low. Make sure there is no flat tire. If the warning light comes on again even after air is put in the tires, a tire may still be flat. If this warning light comes on, the action you must take is completely different depending on the type of tires used. You must understand how to distinguish tires between standard tires and run-flat tires in order to operate your vehicle safely and should refer to page 341. If you drive over about 180 km/h (112 mph) with the tires not inflated at the designated pressure for high speed driving, the warning light may turn on. If the tires are at the designated pressure for ordinary speed driving, decreasing the speed will turn off the warning light. (For the designated pressure for high speed driving, see "Specifications" on page 326.) This warning light may turn on due to natural causes such as natural air leaks or tire inflation pressure changes caused by temperature. In this case, adjusting the tire inflation pressure will turn off the warning light. For details about adjusting the tire inflation pressure, see "Checking tire inflation pressure" on page 329. 49
