Your Driving and the Road
parking on Hills
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 the Index
under Parking Brake). 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.
Here's how:
Parking Downhill
Turn your wheels to the right.
You don't have to jam your tires against
the curb, if there is a curb. A gentle
contact is all you need.
Parking Uphill
If there is a curb, turn your wheels to
the left if the curb is at the right side of
your vehicle.
