Stalling on an Incline If your vehicle stalls when you're crossing an incline, be sure you (and your passengers) get out on the uphill side, even if the door there is harder to open. If you get out on the downhill side and the vehicle starts to roll over, you'll be right in its path. ~ ~ If you have to walk down the slope, stay out of the path the vehicle will take if it does rollover. Getting out on the downhill (low) side a vehicle of If stopped across an incline is dangerous. the be vehicle rolls over, you could crushed or killed. Always get out on the uphill (high) side of the vehicle and stay well clear the rollover path. of Driving in Mud, Sand, Snow or Ice When youdrive in mud, snow or sand, your wheels won't get good traction. You can't accelerate as quickly, turning is more difficult, and you'll need longer braking distances. It's best to use a low gear when you're in mud -- the deeper the mud, the lower the gear. In really deep mud, the idea is to keep your vehicle moving so you don't get stuck. When you drive on sand, you'll sense a change in wheel traction. But it will depend upon how loosely packed the sand is. On loosely packed sand (as on beaches or sand dunes) your tires will tend to sink into the sand. This has an effect on steering, accelerating and braking. You may want to reduce the air pressure in your tires slightly when driving on sand. This will improve traction. 4-26
