Vehicle Stability Assist (VSA ), aka Electronic Stability Control (ESC), System VSA is turned on every time you start the engine, even if you turned it off the last time you drove the vehicle. In certain unusual conditions when your vehicle gets stuck in shallow mud or fresh snow, it may be easier to free it with the VSA temporarily switched off. When the VSA system is off, the traction control system is also off. You should only attempt to free your vehicle with the VSA off if you are not able to free it when the VSA is on. Immediately after freeing your vehicle, be sure to switch the VSA on again. We do not recommend driving your vehicle with the VSA and traction control systems switched off. VSA and Tire Sizes Driving with varying tire or wheel sizes may cause the VSA to malfunction. When replacing tires, make sure they are of the same size and type as your original tires (see page 574 ). If you install winter tires, make sure they are the same size as those that were originally supplied with your vehicle. Exercise the same caution during winter driving as you would if your vehicle was not equipped with VSA. Hill Start Assist On models with SH-AWD Your vehicle is equipped with a hill start assist feature to help prevent the vehicle from rolling on inclines as you move your foot from the brake pedal to the accelerator. To activate hill start assist, you must come to a complete stop and make sure the shift lever is either in D or S when facing uphill, or reverse when facing downhill. This feature begins working a few seconds after you are in the correct gear position. Release the brake pedal. The brakes remain engaged briefly to keep the vehicle from rolling forward or backward. Gently apply the accelerator pedal as in normal driving. Hill start assist will release brake pressure gradually as you accelerate. Driving 512 2013 TL
