Driving on Grades
Notice: Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher
than normal engine and transmission temperatures
may result and damage your vehicle. Frequent
stops are very important to allow the engine and
transmission to cool.
Reduce speed and shift to a lower gear before you
start down a long or steep downgrade. If you do not
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 the engine and the transmission
overheating. If your engine does overheat, see
Engine Overheating on page 5-23.
Parking on Hills
{CAUTION:
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 do not shift into
PARK (P).
When parking uphill, turn your wheels away from
the curb. When parking downhill, turn your wheels
into the curb.
2. Have someone place chocks behind the trailer
wheels.
