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...
