230 STARTING AND OPERATING Automatic Transmission Shifting from D (Drive) to P (Park) or R (Reverse) (or from P or R to D) should be done only after the accelerator pedal is released and the vehicle is stopped. Be sure to keep your foot on the brake when moving the shift lever between these gears. WARNING! It is dangerous to shift the selector lever out of "P" or "N" if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal. Brake Transmission Shift Interlock System This vehicle is equipped with a brake transmission shift interlock system (BTSI), which holds the gearshift lever in the P (Park) position when the ignition switch is in the OFF position. To move the gear selector lever out of the P (Park) position, turn the ignition switch to the ON position, and press the brake pedal and the button on the front of the shifter handle.
