planning to visit there, here are some tips that
can make your trips safer and more enjoyable.
See Off-Road Driving on page 372 for information
about driving off-road.
•
Keep your vehicle in good shape. Check all
fluid levels and also the brakes, tires, cooling
system, and transmission. These parts can
work hard on mountain roads.
CAUTION:
{
If you do not shift down, your brakes
could get so hot that they would not work
well. You would then have poor braking or
even none going down a hill. You could
crash. Shift down to let your engine assist
your brakes on a steep downhill slope.
