Navigation System Information

Navigation systems use the Global Positioning System (GPS) - a network of communications satellites placed in precise, very high orbits around the earth. These satellites continuously transmit signals that are received by the vehicle's navigation system. The vehicle's navigation system receives signals from three of these satellites simultaneously. By using triangulation, it then can determine the vehicle's location with an incredible degree of accuracy anywhere on the earth. Typically, the navigation system will be able to pinpoint a vehicle's location to within a few yards.

Bluetooth Information

The Bluetooth® feature is a wireless communication system for consumer mobile devices. Wireless communication between devices is done on a 2.4 GHz frequency band that is prescribed by the Bluetooth Special Interest Group. Communication speed is 12Mbps (Megabytes per second). Transmission range is approximately 33 feet.

Vehicle Stability Control (VSC)

More consumers are aware of electronic stability control (ESC), which is the generic term for technology that helps the driver maintain control and directional stability of the vehicle in a turn. ESC is gaining favor among consumer safety groups, lawmakers and regulatory bodies. Scientific studies have demonstrated the effectiveness of this safety feature, especially in lowering the risk of single-vehicle accidents. With ESC generating so much interest, more safety-minded shoppers are requesting electronic stability control.

The Tundra's version of ESC is called Vehicle Stability Control or VSC. This safety feature is standard on all Tundras and is part of the comprehensive STAR safety system.

VSC is an extension of Tundra's sophisticated electronic brake-control system. A computer monitors a network of sensors to compare the vehicle's speed and direction with the driver's steering-wheel position and throttle input. If the computer senses a deviation between the driver's intended path and the vehicle's direction, VSC will modulate the brakes individually and manipulate the throttle to help the vehicle return to course. VSC is not a traction-control feature; it is a vehicle-control feature.

In certain situations such as off-road maneuvering over difficult terrain, VSC may inhibit experienced drivers. VSC can be turned off using a dash-mounted switch but will return automatically if the engine is turned off and then started again.
