2010 Chevrolet Suburban 2500 Owner's Manual - Page 384

If, after stalling, you try to back down the hill and decide you just cannot do it, set the parking brake, put your transmission in P (Park), and turn off the engine. Leave the vehicle and go get some help. Exit on the uphill side and stay clear of the path the vehicle would take if it rolled downhill. If the vehicle has a transfer case with a N (Neutral) position, do not shift the transfer case to Neutral when you leave the vehicle. Leave it in some gear. Driving Downhill When off-roading takes you downhill, consider: . How steep is the downhill? Will I be able to maintain vehicle control? What is the surface like? Smooth? Rough? Slippery? Hard-packed dirt? Gravel? Are there hidden surface obstacles? Ruts? Logs? Boulders? What is at the bottom of the hill? Is there a hidden creek bank or even a river bottom with large rocks? . . { WARNING: If the vehicle has the two‐speed automatic transfer case, shifting the transfer case to Neutral can cause your vehicle to roll even if the transmission is in P (Park). This is because the Neutral position on the transfer case overrides the transmission. You or someone else could be injured. If you are going to leave your vehicle, set the parking brake and shift the transmission to P (Park). But, if the vehicle has a two‐speed automatic transfer case, do not shift the transfer case to Neutral. . If you decide you can go down a hill safely, try to keep the vehicle headed straight down. Use a low gear so engine drag can help the brakes so they do not have to do all the work. Descend slowly, keeping the vehicle under control at all times. 5-20
