7-38 Starting and operating/Tire pressure monitoring system (TPMS) (U.S.-spec. models) Control OFF indicator light turns off. With the Vehicle Dynamics Control system deactivated, traction and stability en- hancement offered by Vehicle Dynamics Control system is unavailable. Therefore you should not deactivate the Vehicle Dynamics Control system except under above-mentioned situations. NOTE . When the switch has been pressed to deactivate the Vehicle Dynamics Control system, the Vehicle Dynamics Control system automatically reacti- vates itself the next time the ignition switch is turned to the “LOCK”/“OFF” position and the engine is restarted. . If the switch is held down for 30 seconds or longer, the indicator light turns off, the Vehicle Dynamics Control system is activated, and the system ignores any further pressing of the switch. To make the switch usable again, turn the ignition switch to the “LOCK”/“OFF” position and restart the engine. . When the switch is pressed to deactivate the Vehicle Dynamics Con- trol system, the vehicle’s running per- formance is comparable with that of a vehicle that does not have a Vehicle Dynamics Control system. Do not de- activate the Vehicle Dynamics Control system except when absolutely neces- sary. . Even when the Vehicle Dynamics Control system is deactivated, compo- nents of the brake control system may still activate. When the brake control system is activated, the Vehicle Dy- namics Control operation indicator light flashes. Tire pressure monitoring system (TPMS) (U.S.-spec. models) S07AO Low tire pressure warning light The tire pressure monitoring system pro- vides the driver with a warning message when tire pressure is severely low. The tire pressure monitoring system will activate only when the vehicle is driven at speeds above 20 mph (32 km/h). Also, this system may not react immediately to a sudden drop in tire pressure (for example, a blow-out caused by running over a sharp object).
