Driving On Grades
Reduce speed and shift to a:lower gear before you start
down a long or steep doyngrade. If you don't shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around 45 mph (70 km/h) to reduce the
possibility of engine and transmission overheating.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than
at
normal altitudes. If you turn
your engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating. To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in PARK
(P)
for a few
minutes before turning the engine off.. If you do get the
overheat warning, see "Engine Overheating" in the Index.
Parking on.Hills
You really should not park your vehicle, with a trailer
attached, .on a hill.
If
something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but don't shift into
PARK (P) yet. Then turn your wheels into the curb
if facing downhill or into traffic if facing ,uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Re-apply the regular brakes. Then apply your
parking brake and then shift to
PARK
(P).
5. Release the regular brakes.
