Making Turns
Notice: Making very sharp turns
while trailering could cause
the trailer to come in contact with
the vehicle. The vehicle could
be damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer won't strike soft shoulders,
curbs, road signs, trees or other
objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
flash whenever signaling a turn
or lane change. Properly hooked up,
the trailer lamps also flash, telling
other drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument panel flash for
turns even if the bulbs on the trailer
are burned out. For this reason
you may think other drivers
are seeing the signal when they are
not. It is important to check
occasionally to be sure the trailer
bulbs are still working.
Driving on Grades
Because of the added load of the
trailer, the vehicle's engine may
overheat on hot days, when going up
a long or steep grade with a trailer. If
the engine coolant temperature gage
indicates overheating, turn off the air
conditioning to reduce engine load,
pull off the road and stop in a safe
spot. Let the engine run while
parked, preferably on level ground,
with the transmission in P (Park) for
a few minutes before turning the
engine off.
Driving Your Vehicle
Reduce speed and shift to a lower
gear before starting down a long
or steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
On a long uphill grade, shift down
and reduce the vehicle speed
to around 55 mph (88 km/h) to
reduce the possibility of the engine
and the transmission overheating.
