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: • Reduce the frequency and improve the predictability of transmission shifts when pulling a heavy trailer or a large or heavy load. Tow/Haul is designed to be most effective when the vehicle and trailer combined weight is at least 75 percent 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: • When pulling a heavy trailer or a large or heavy load through rolling terrain. • Provide the same solid shift feel when pulling a heavy trailer or a large or heavy load as when the vehicle is unloaded. • When pulling a heavy trailer or a large or heavy load in stop and go traffic. • Improve control of vehicle speed while requiring less throttle pedal activity when pulling a heavy trailer or a large or heavy load. Your vehicle may be equipped with a button at the end of the shift lever which, when pressed, enables tow/haul. Your vehicle may be equipped with Autoride® which further improves your vehicle's ride while towing. See Autoride® on page 4-62 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. • 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. Operating the vehicle in tow/haul when lightly loaded or with no trailer at all will not cause damage. However, there is no benefit to the selection of Tow/Haul when the vehicle is unloaded. Such a selection when unloaded may result in unpleasant engine and transmission driving characteristics and reduced fuel economy. Tow/Haul is recommended only when pulling a heavy trailer or a large or heavy load. 4-64
