Whatever the condition -- smooth ice, packed, blowing or loose snow -- drive with caution. If you have traction control, keep the system on. It will improve your ability to accelerate when driving on a slippery road. But you can turn the traction control system off if you ever need to. You should turn the system off if your vehicle ever gets stuck in sand, mud, ice or snow. See "Rocking Your Vehicle" in the Index. Even though your vehicle has a traction control system, you'll want to slow down and adjust your driving to the road conditions. See "Traction Control System" in the Index. If you don't have traction control, accelerate gently. Try not to break the gentle traction. If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more. What's 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's 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. 4-26
