Buick RIVIERA 1993 Manual page 177

As you go over the top of a hill, be alert. There could
be something in your lane, like a stalled car or an
accident.
Parking on Hills
You may see highway signs on mountains that warn
of
special problems. Examples are long grades,
passing or no-passing zones, a falling rocks area, or
winding roads. Be alert to these and take appropriate
action.
Winter driving can present special problems. See
,
"Winter Driving" in the Index.
Hills and mountains mean spectacular scenery. But
please be careful where you stop if you decide to look at
the view or take pictures. Look for pull-offs or parking
areas provided for scenic viewing.
Another part of this manual tells how to use your
parking brake (see "Parking Brake" in the Index). But
on a mountain or steep hill, you can do one more thing.
You can
turn
your front wheels to keep your vehicle
from rolling downhill or out into traffic.
