Chevrolet 2007 HH7 Owner's Manual page 265

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.
If your vehicle has the Enhanced Traction System
(ETS), it will improve your ability to accelerate
when driving on a slippery road. Even though your
vehicle has this system, you will want to slow
down and adjust your driving to the road
conditions. Under certain conditions, you may
want to turn the ETS off, such as when driving
through deep snow and loose gravel, to help
maintain vehicle motion at lower speeds. See
Enhanced Traction System (ETS) on page 246.
If your vehicle does not have ETS, accelerate
gently. Try not to break the fragile traction. If you
accelerate too fast, the drive wheels will spin
and polish the surface under the tires even more.
Unless your vehicle has the Anti-Lock Brake
System (ABS), you will want to brake very gently,
too. If your vehicle does have ABS, see
Anti-Lock Brake System (ABS) on page 243. ABS
improves your vehicle's stability when you
make a hard stop on a slippery road. Whether
your vehicle has ABS or not, you will want to begin
stopping sooner than you would on dry pavement.
Without ABS, 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.
