Subaru Forester: Connecting a trailer / Side mirrors

After hitching a trailer to your vehicle,
check that the standard side mirrors
provide a good rearward field of view
without significant blind spots. If significant
blind spots occur with the vehicle’s standard
side mirrors, use towing mirrors that
conform with Federal, state/province and/
or other applicable regulations.
CAUTION
Direct splicing or other improper
connection of trailer lights may
damage your vehicle’s electrical
system and cause a malfunction of
your vehicle’s lighting system...

The wheels and tires are important and
integral parts of your vehicle’s design; they
cannot be changed arbitrarily. The tires
fitted as standard equipment are optimally
matched to the characteristics of the
vehicle and were selected to give the best
possible combination of running performance,
ride comfort, and service life...
