■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. ( →P. 405)
● If the replaced fuse blows again, have the vehicle inspected by your
SUBARU dealer.
■ If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
WARNING
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage, and possibly a fire or injury.
●Never use a fuse of a higher amperage rating than indicated, or use any
other object in place of a fuse.
● Always use a genuine SUBARU fuse or equivalent.
● Do not modify the fuse or the fuse box.
CAUTION
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your
SUBARU dealer.

WARNING
■
Replacing light bulbs
● Only replace a bulb when it is cool enough to touch. Do not attempt to
replace bulbs while they are hot, as doing so may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
● Fully install the light bulbs and any parts used to secure them. Failure to
do so may result in heat damage, fire, or water entering a light unit. This
may damage the light or cause condensation to build up on the inner side
of the lens.
■ When changing the back-up lights
Stop the engine and wait until the exhaust pipes have cooled down suffi-
ciently. The lights are located near the exhaust pipe and touching a hot
exhaust pipe can cause burns.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.

Hazard war ning flashers
■Hazard warning flashers

vehicle has to be stopped in the road due to a breakdown, etc.
Press the switch.
All the turn signal lights will
flash. To turn them off, press
the switch once again.
When the turn signal lights are

■Before emergency towing
Release the parking brake.
Shift the select lever to N (vehicles with an automatic transmission)
or shift lever to neutral (vehicles with a manual transmission).
Vehicles without a keyless access with push button start system:
Turn the engine switch to the “A CC” (engine off) or “ON” (engine
running) position.
Vehicles with a keyless access with push button start system: Turn
the push-button ignition switch to “ACC” (engine off) or “ON”
(engine running) mode.
■ If towing a vehicle
Do not tow another vehicle. If towing a vehicle that has broken down is
unavoidable, avoid towing a vehicle that is heavier than your vehicle. Also,
do not pull out a vehicle that has fallen into a ditch.
WARNING
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
● If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.

Towing with a sling-type truck
WARNING
■
Installing towing eyelets to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelets may come loose during towing. This
may lead to accidents that cause serious injury or even death.
■ After towing
● Always remove the towing eyelet. Failure to do so can cause the SRS air-
bags to not operate correctly in the event of a frontal collision.
● Always remove the towing eyelets. Failure to do so may prevent the fuel
pump shut off system from operating properly if the vehicle receives an
impact from the rear.
