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:
Before going down a steep hill, slow
down and shift to a lower gear (if necessary,
use 1st gear) in order to utilize the
engine braking effect and prevent overheating
of your vehicle’s brakes. Do not
make sudden downshifts.
When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating...
The SRS side airbag and SRS curtain
airbag are designed as follows:
To deploy in the event of an accident
involving a moderate to severe side impact
collision
To function on a one-time-only basis
The SRS side airbag and SRS curtain
airbag are not designed to deploy in the
following cases:
In most lesser side impacts
In most frontal or most rear impacts
(because the SRS side airbag and SRS
curtain airbag deployment would not protect
the occupant in those situations)
The SRS curtain airbags are also designed
to deploy when the vehicle is in an
extremely inclined state such as during a
rollover...
