GM None Pontiac Aztek - Manual (Page 276)

Unless you have the anti-lock braking system, you will
want to brake very gently, too. (If you do have anti-lock,
see Braking on page 4-7. This system improves your
vehicle’s stability when you make a hard stop on a
slippery road.) Whether you have the anti-lock braking
system or not, you will want to begin stopping sooner
than you would on dry pavement. Without anti-lock
brakes, if you feel your vehicle begin to slide, let up on
the brakes a little. Push the brake pedal down steadily
to get the most traction you can. Remember, unless you have anti-lock, if you brake so
hard that your wheels stop rolling, you will just slide.
Brake so your wheels always keep rolling and you can
still steer.
• Whatever your braking system, 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 can not reach: 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.
