Driving tips
T 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.
T Trailer lights
Connection of trailer lights to your vehicle's electrical
system requires modifications to the vehicle's lighting
circuit to increase its capacity and accommodate wir-
ing changes. To ensure the trailer lights are connected
properly, please consult your SUBARU dealer. Check
8-32
for proper operation of the turn signals, the brake
lights and parking lights each time you hitch up.
Direct splicing or other improper connection of
trailer lights may damage your vehicle's electri-
cal system and cause a malfunction of your ve-
hicle's lighting system.
T Tires
Make sure that all the tires on your vehicle are properly
inflated to the pressure specified on the tire placard lo-
HS8022BA
cated on the driver's side center pillar.
Trailer tire condition, size, load rating and proper infla-
tion pressure should be in accordance with the trailer
manufacturer's specifications.
