Vehicle Stability Assist (VSA ), aka Electronic Stability Control (ESC), System 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 506 ). 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 Your vehicle is equipped with a hill start assist feature to help prevent the vehicle from rolling on steep inclines as you move your foot from the brake pedal to the accelerator. This feature operates for up to 1.5 seconds in any drive gear position (when faced uphill) or in reverse (when faced downhill). This feature requires that the vehicle has come to a complete stop before it can work. Hill start assist may not hold a heavily loaded vehicle, such as when your vehicle is connected to a trailer, or prevent your vehicle from rolling downhill on a very steep or slippery slope.
