Making Turns
Notice: Making very sharp turns while
trailering could 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, make wider
turns than normal. Do this 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
When you tow a trailer, your vehicle may
need additional wiring. Check with your
dealer/retailer. 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 to
check occasionally to be sure the trailer bulbs
are still working.
Driving On Grades
When towing a trailer on long uphill grades while
the outside temperature is above 85°F (29°C),
reduce your vehicle speed to 45 mph (72 km/h)
to avoid overheating the engine cooling system.
Reduce speed and shift to a lower gear before
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.
Pay attention to the engine coolant gage.
If the indicator is in the red area, turn off the
air conditioning to reduce engine load. See
Engine Overheating on page 371.
