Q: Are there some things I should not do when driving down a hill? A: Yes! These are important because, if you ignore them, you could lose control and have a serious accident. • When driving downhill, avoid turns that take you across the incline of the hill. A hill that is not too steep to drive down may be too steep to drive across. You could roll over if you do not drive straight down. • Never go downhill with the transmission in NEUTRAL (N). This is called "free wheeling." The brakes will have to do all the work and could overheat and fade. Q: Am I likely to stall when going downhill? A: It is much more likely to happen going uphill. But if it happens going downhill, here is what to do. 1. Stop your vehicle by applying the regular brakes. Apply the parking brake. 2. Shift to PARK (P) and, while still braking, restart the engine. 3. Shift back to a low gear, release the parking brake, and drive straight down. 4. If the engine will not start, get out and get help. 309
