STARTING AND DRIVING 5. Release the parking brake and brake pedal. Depress the accelerator pedal slowly for smooth starting. In normal cruising, the vehicle will start in the first gear and automatically shift up to the most suitable gear. On inclines, declines or winding roads, etc., the vehicle shifts up and down automatically according to the running conditions to obtain the suitable driving power and engine braking. In "4" position, the automatic transmission system will select the most suitable gear for the running conditions such as hill climbing, hard towing, etc. If you need to accelerate rapidly while driving, depress the accelerator pedal to the full throttle position. This provides more acceleration by automatically downshifting the transmission to the next lower gear or beyond, depending on the vehicle speed. If engine braking is needed, such as in descending a long hill, see "(b) Using engine braking". (b) Using engine braking 31L010-3 236
