know about. They're called Range Selection Mode, and Tow/haul Mode. The Range Selection Mode literally gives you fingertip control of the transmission gear range. This can help control vehicle speed while driving downhill or towing a trailer… It lets you select a desired range of gears. To use this feature, do the following: Move the shift lever to the Manual position. Then press the plus-minus buttons on the steering column shift lever, to select the desired range of gears for the current driving conditions. As you're driving, the vehicle will automatically shift up and down within this gear range,, but will never exceed your chosen gear. While using Range Selection Mode, Cruise Control and the Tow/Haul Mode can be used, but Grade Braking is not available in this mode. The other transmission mode you should understand is the Tow/Haul Mode. This feature changes transmission points to smooth shifting while trailering, or driving up or down hills. The selector button is located on the end of the steering column shift lever. When Tow/Haul Mode is selected the tow/haul indicator light will come on. You can use this feature to assist when you're doing some serious driving: like down steep hills or mountain grades, towing, or hauling a heavy load. The transmission will automatically adjust to those conditions for you. Low traction mode assists in vehicle acceleration when road conditions are slippery, like when there's ice or snow. Low Traction Mode is activated by shifting to "M2". This will cause the transmission to start out in 2nd gear as opposed to 1st gear, and help reduce the chance of tire spin on a slippery surface by delivering less torque to the rear wheels. Note: It is active automatically when in Tow/Haul mode. Grade Braking is available and UTILIZED in Tow/Haul mode. It assists in maintaining desired vehicle speeds when driving on downhill grades. Grade Braking monitors things like, vehicle speed, acceleration, engine torque and brake pedal usage. This feature automatically utilizes the engine and transmission to slow the vehicle, and helps reduce wear on the braking system. So... when your needs involve climbing a mountain or hauling heavy stuff, your Yukon's “6 Speed Auto Trans with "tap up-down shift" & "Tow Haul transmission” , offers easy-to-use customizable features that will give you added control & power... Enjoy !
