Main Menu Table Of Contents 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 Activation Indicator When VSA activates, you will see the VSA activation indicator blink (see page 67 ). Vehicle Stability Assist (VSA) System Indicator If this indicator comes on while driving, 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 or comes back on while driving, have the VSA system inspected by your dealer. NOTE: The main function of the VSA system is generally known as Electronic Stability Control (ESC). The system also includes a traction control function. 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. You will also see a ''CHECK VSA SYSTEM'' message on the multiinformation display if there is a problem with the VSA system. If the low tire pressure/TPMS indicator comes on (see page 307 ), or the multi-information display shows a ''CHECK TPMS SYSTEM'' message with the indicator flashing (see page 310 ), the VSA system automatically turns on even if the VSA system is turned off with the VSA OFF switch. In this case, you cannot turn the VSA system off by pressing the VSA OFF switch again. 312 2009 RDX
