180 STARTING AND OPERATING Brake Transmission Shift Interlock System (BTSI) This vehicle is equipped with a brake transmission shift interlock system (BTSI) that holds the gearshift lever in the P (Park) position when the ignition switch is in an unlocked position. To move the gear selector lever out of the P (Park) position, the ignition switch must be turned to the OFF, ON, or START position, the brake pedal and the button on the front side of the shifter handle must be depressed. Electronically Controlled Five Speed Automatic Transmission (4.7L Engine Only) This electronically controlled transmission provides a precise shift schedule. The transmission electronics are self calibrating; therefore, the first few shifts on a new vehicle may be somewhat abrupt. This is a normal condition, and precision shifts will develop within a couple hundred miles (kilometers). Protect Mode - Electronically Controlled Transmission (4.7L Engine Only) This transmission is monitored electronically for abnormal conditions. If an abnormal condition is detected, the transmission's electronic controller will automatically select direct gear (in the Drive position) or 2nd gear (in the 2 or 1 position). This feature will allow the vehicle to be driven to the dealer for service minimizing any damage to the transmission. Some conditions that will cause the transmission to use this alternate gear selection are momentary and the transmission can be reset to the normal shift program by performing the following: • Stop the vehicle and shift into P (Park). • Turn the ignition key to the OFF position and then restart the engine. • Shift into the desire shift range and resume driving.
