342 STARTING AND OPERATING Gear Ranges NOTE: Under extreme cold temperatures (-10°F (-23°C) and when in DRIVE, transmission operation may be briefly limited to only second gear operation. Normal operation will resume once the transmission temperature has risen to a suitable level. DO NOT race the engine when shifting from PARK or NEUTRAL position into another gear range. WARNING! • Never use the PARK position as a substitute for the parking brake. Always apply the parking brake fully when parked to guard against vehicle movement and possible injury or damage. • It is dangerous to move the shift lever out of PARK or NEUTRAL if the engine speed is higher than the 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. PARK This range supplements the parking brake by locking the transmission. The engine can be started in this range. Never use PARK while the vehicle is in motion. Apply the parking brake when leaving the vehicle in this range. Always apply the parking brake first, then place the shift REVERSE lever in the PARK position. This range is for moving the vehicle backward. Use only after the vehicle has come to a complete stop.
