StabiliTrak® will improve your ability to accelerate when driving on a slippery road. But you can turn StabiliTrak® off if you ever need to. See StabiliTrak® System on page 4-9 and If Your Vehicle is Stuck in Sand, Mud, Ice or Snow on page 4-44. Even with StabiliTrak®, you will want to slow down and adjust your driving to the road conditions. Under certain conditions, you may want to turn StabiliTrak® off, such as when driving through deep snow and loose gravel, to help maintain vehicle motion at lower speeds. Your Anti-Lock Brake System (ABS) improves your vehicle's stability when you make a hard stop on a slippery road. Even though you have ABS, you will want to begin stopping sooner than you would on dry pavement. See Anti-Lock Brake System (ABS) on page 4-7. What is the worst time for this? Wet ice. Very cold snow or ice can be slick and hard to drive on. But wet ice can be even more trouble because it may offer the least traction of all. You can get wet ice when it is about freezing, 32°F (0°C), and freezing rain begins to fall. Try to avoid driving on wet ice until salt and sand crews can get there. Whatever the condition - smooth ice, packed, blowing, or loose snow - drive with caution. • Allow greater following distance on any slippery road. • Watch for slippery spots. The road might be fine until you hit a spot that is covered with ice. On an otherwise clear road, ice patches may appear in shaded areas where the sun cannot reach, such as around clumps of trees, behind buildings, or under bridges. Sometimes the surface of a curve or an overpass may remain icy when the surrounding roads are clear. If you see a patch of ice ahead of you, brake before you are on it. Try not to brake while you are actually on the ice, and avoid sudden steering maneuvers. 4-41
