Turn Signals When Towing a Trailer

When towing a trailer, the vehicle may need a different
turn signal flasher and/or extra wiring. Check with your
dealer. The arrows on the instrument panel will flash
whenever signaling a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you are about to turn, change lanes or stop.
When towing a trailer, the arrows on the instrument
panel will flash for turns even if the bulbs on the trailer
are burned out. You may think drivers behind you
are seeing your signal when they are not. It is important
to check occasionally to be sure the trailer bulbs are
still working.

Driving On Grades

Reduce speed and shift to a lower gear before starting
down a long hill or steep downgrade. If the vehicle 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's speed to around 45 mph (70 km/h) to reduce
the possibility of engine and transaxle overheating.
If towing a trailer, you may want to drive in THIRD (3)
