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.

down a long or steep downgrade. If you don't shift

speed to around 45 mph (70 km/h) to reduce the
possibility of engine and transmission overheating.

DRIVE (D) when towing a trailer. Operating
your
vehicle in DRIVE ( D ) when towing
a
trailer will
minimize heat buildup and extend the life of your
transmission. Or. if you have a manual transmission. it's

similar to engine overheating. To avoid this. let the
engine run while parked (preferably on level ground)
