Whatever the condition - smooth ice, packed, blowing, or loose snow - drive with caution. 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 363 and If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 406. 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. 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. 403
