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. If you have an automatic transmission, shift to PARK (P). 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. Driving Across an Incline Sooner or later, an off-road trail will probably go across the incline of a hill. If this happens, you have to decide whether to try to drive across the incline. Here are some things to consider: • A hill that can be driven straight up or down may be too steep to drive across. When you go straight up or down a hill, the length of the wheel base - the distance from the front wheels to the rear wheels - reduces the likelihood the vehicle will tumble end over end. But when you drive across an incline, the much more narrow track width - the distance between the left and right wheels - may not prevent the vehicle from tilting and rolling over. Also, driving across an incline puts more weight on the downhill wheels. This could cause a downhill slide or a rollover. 266
