Vehicle Stability Assist (VSA ), aka Electronic Stability Control (ESC), System If the low tire pressure/TPMS indicator comes on (see page 423 ), or the multi-information display shows a ''CHECK TPMS SYSTEM'' message with the indicator flashing (see page 427 ), 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. VSA OFF Switch 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 OFF SWITCH When VSA is off, the VSA activation indicator comes on as a reminder. Press and hold the switch again. It turns the system back on. VSA is turned on every time you start the engine, even if you turned it off the last time you drove the vehicle. 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 479 ). This switch is at the right side of the left vent. Press and hold it until you hear a beep. 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. 430 2010 RL
