D You can tow in DRIVE (D). You may want to shift the transmission to THIRD (3) or, if necessary, a lower gear selection if the transmission shifts too often (e.g., under heavy loads and/or hilly conditions). If you have a manual transmission and you are towing a trailer, it's better not to use the highest gear. See "Tow/Haul Mode" in the Index. Three important considerations have to do with weight: D the weight of the trailer, D the weight of the trailer tongue D and the weight on your vehicle's tires. Tow/Haul Mode Tow/haul is a feature that assists when pulling a heavy trailer or a large or heavy load. The purpose of the tow/haul mode is to: D Reduce the frequency and improve the predictability of transmission shifts when pulling a heavy trailer or a large or heavy load. D Provide the same solid shift feel when pulling a heavy trailer or a large or heavy load as when the vehicle is unloaded. D Improve control of vehicle speed while requiring less throttle pedal activity when pulling a heavy trailer or a large or heavy load. Your vehicle is equipped with a button at the end of the shift lever which, when pressed, enables tow/haul. Your vehicle may be equipped with AutorideR which further improves your vehicle's ride while towing. See "AutorideR" in the Index for more information. When the button is pressed, a light on the instrument panel will illuminate to indicate that tow/haul has been selected. Tow/haul may be turned off by pressing the button again, at which time the indicator light on the instrument panel will turn off. The vehicle will automatically turn off tow/haul every time it is started. Tow/haul is designed to be most effective when the vehicle and trailer combined weight is at least 75% of the vehicle's Gross Combined Weight Rating (GCWR). See "Weight of the Trailer" later in this section. Tow/haul is most useful under the following driving conditions: D When pulling a heavy trailer or a large or heavy load through rolling terrain. in stop and go traffic. D When pulling a heavy trailer or a large or heavy load D When pulling a heavy trailer or a large or heavy load in busy parking lots where improved low speed control of the vehicle is desired. 4-57
