Hummer 2007 H3 - Manual (Page 282)

Include an ice scraper, a small brush or broom,
a supply of windshield washer fluid, a rag,
some winter outer clothing, a small shovel, a
flashlight, a red cloth, and a couple of reflective
warning triangles. And, if you will be driving under
severe conditions, include a small bag of sand,
a piece of old carpet, or a couple of burlap bags
to help provide traction. Be sure you properly
secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where the tires
meet the road probably have good traction.
However, if there is snow or ice between the
tires and the road, you can have a very slippery
situation. You will have a lot less traction, or
grip, and will need to be very careful.
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.
