d2ureepe,
Do not attempt to straighten out the tow
vehicle and trailer by increasing the speed.
If the transmission shifts between gears on
R
inclines repeatedly, shift to a lower gear
range manually (
2 or 1.
A lower gear and reduction of speed
reduces the chance of engine overloading
and/or overheating.
When going down an incline, shift into a
R
lower gear and use the engine's braking
effect.
Avoid riding the brakes, thus overheating
the vehicle and trailer brakes (if so
equipped).
If the engine coolant rises to an extremely
R
high temperature when the air conditioning
is on, turn off the air conditioning system.
Engine coolant heat can be additionally
vented by opening the windows, switching
the climate control fan speed to high and
setting the temperature control to the
maximum.
During a passing maneuver extreme care
R
must be exercised since your vehicle with
a trailer will require additional passing
distance ahead than when driving without
a trailer.
Because your vehicle and trailer is longer
than your vehicle alone, you will also need
to go much farther ahead of the passed
vehicle before you can return to your lane.
