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...
Other information:
WARNING
Always use safety chains between
your vehicle and the trailer. Towing
trailer without safety chains could
create a traffic safety hazard if the
trailer separates from the hitch due
to coupling damage or hitch ball
damage.
In case the trailer hitch connector or hitch
ball should break or become disconnected,
the trailer could get loose and
create a traffic safety hazard...
