cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you're turning with
a
trailer, n ~ k e wider turns than

so
your 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 your instrument panel
will
flash
whenever you signal
a
turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you're about to turn, change lanes or stop.
When towing
a
trailer, the arrows on your instrument
panel will flash for turns even if the bulbs
on
the trailer
are burned out. Thus, you may
think
drivers behind you
are seeing your signal when they are not.
It's
important
t o
check occasionally to be sure the trailer bulbs are
still working.
Reduce speed and shift to
a
lower gear h~fi>re you start
down a long or steep downgrade. 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.
If you have an automatic transmission, you can tow in
AUTOMATIC OVERDRIVE
(a).
You may want to
shift the transmission to THIRD ( 3 ) or, if necessary, a
lower gear selection if the transmission shifts too often
(e.g., under heavy loads and/or hilly conditions).
When towing
a t
high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than at normal altitudes. I f 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 j for
a
few
minutes before turning the engine off. I f you do get the
overheat warning. see "Engine Overheating" in
the Index.
