Mercury 1996 Sable Manual page 235

Drive slower than you normally would.
Give your vehicle more distance to stop.
Pump the brake pedal steadily and evenly to
avoid locking your wheels. (Does not apply
to vehicles with anti-lock brakes.)
Consider using one of the lower gears.
To avoid skidding and losing control
on slippery roads, do not downshift
into 1 (First) when you are moving
faster than 20 mph (32 km/h).
If your vehicle has speed control, do
not use it on slippery roads. You
could lose control of your vehicle
and could injure someone.
If your vehicle gets stuck (for example, in mud
or snow), you may try to "rock" it out of the
spot. Shift, in a steady rhythm, between forward
and reverse gears. While in each gear, press
lightly on the accelerator and release.
Do not spin the wheels at over
35 mph (56 km/h). If you do, the
tires may fail and injure a passenger
or bystander.
