Vehicle Stability Assist (VSA ), aka Electronic Stability Control (ESC), System The vehicle stability assist (VSA) system helps to stabilize the vehicle during cornering if the vehicle turns more or less than desired. It also assists you in maintaining traction while accelerating on loose or slippery road surfaces. It does this by regulating the engine's output, and by selectively applying the brakes. When VSA activates, you may notice that the engine does not respond to the accelerator in the same way it does at other times. There may also be some noise from the VSA hydraulic system. You will also see the VSA activation indicator blink. The VSA system cannot enhance the vehicle's driving stability in all situations and does not control your vehicle's entire braking system. It is still your responsibility to drive and corner at reasonable speeds and to leave a sufficient margin of safety. VSA Off Indicator When VSA is off, the VSA off indicator comes on as a reminder. Vehicle Stability Assist (VSA) System Indicator When VSA activates, you will see the VSA system indicator blink. If this indicator comes on while driving, you will also see a ''CHECK VSA SYSTEM'' and/or ''CHECK HILL START ASSIST SYSTEM'' message on the multi-information display. Drive cautiously as the VSA may not be functioning. Without VSA, your vehicle will have normal braking and cornering ability, but it will not have VSA traction and stability enhancement. Also, the VSA OFF switch will not operate. Pull to the side of the road when it is safe, and turn off the engine. Reset the system by restarting the engine. If the VSA system indicator stays on, have the VSA system inspected by your dealer. If the indicator does not come on when the ignition switch is turned to the ON (II) position, there may be a problem with the VSA system. Have your dealer inspect your vehicle as soon as possible. : Models equipped with the keyless access system have an engine start/stop button instead of an ignition switch. ON Mode is the equivalent of ON (II). For more information, see pages 178 and 181 . NOTE: The main function of the VSA system is generally known as Electronic Stability Control (ESC). The system also includes a traction control function. 484 2010 TL
