Maintenance and care
WARNING
■Chemicals in the battery
A battery contains poisonous and corrosive sulfuric acid and may produce
hydrogen gas which is flammable and explosive. To reduce the risk of death
or serious injury, take the following precautions while working on or near the
battery:
●Do not cause sparks by touching the battery terminals with tools.
●Do not smoke or light a match near the battery.
●Avoid contact with eyes, skin and clothes.
●Never inhale or swallow electrolyte.
●Wear protective safety glasses when working near the battery.
●Keep children away from the battery.
■Where to safely charge the battery
Always charge the battery in an open area. Do not charge the battery in a
garage or closed room where there is not sufficient ventilation.
■Emergency measures regarding electrolyte
●If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immedi-
ate medical attention. If possible, continue to apply water with a sponge or
cloth while traveling to the nearest medical facility.
●If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or burning, get medical
attention immediately.
●If electrolyte gets on your clothes
It can soak through clothing on to your skin. Immediately take off the cloth-
ing and follow the procedure above if necessary.
●If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Get emergency medical attention
immediately.

Registering ID codes (vehicles with a tire pressure monitoring
system)
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your SUBARU dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your SUBARU dealer.
■Replacing tires and wheels (vehicles with a tire pressure monitor-
ing system)
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pressure monitoring system will not work properly.
After driving for about 20 minutes, the tire pressure warning light comes
on after blinking for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Low profile tires
Generally, low profile tires will wear more rapidly and tire grip perfor-
mance will be reduced on snowy and/or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains on snowy and/or
icy roads and drive carefully at a speed appropriate for road and weather
conditions.

Maintenance and care
■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. (oP. 342)
●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.

Maintenance and care
■When replacing light bulbs
SUBARU recommends that you use genuine SUBARU products designed
for this vehicle.
Because certain bulbs are connected to circuits designed to prevent over-
load, non-genuine parts or parts not designed for this vehicle may be unus-
able.

WARNING
■Replacing light bulbs
●Turn off the lights. Do not attempt to replace the bulb immediately after
turning off the lights.
The bulbs become very hot and 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 light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
■When changing the back-up lights
Stop the engine and wait until the exhaust pipe has cooled sufficiently. The
lights are located near the exhaust pipe and touching a hot exhaust pipe can
cause burns.

WARNING
■Discharge headlights
●Contact your SUBARU dealer before replacing the discharge headlights
(including light bulbs).
●Do not touch the discharge headlight’s high voltage socket when the head-
lights are turned on.
An extremely high voltage of 25000 V will be discharged and could result
in serious injury or death by electric shock.
●Do not attempt to take apart or repair the low beam discharge headlight
bulbs, connectors, power supply circuits, or related components.
Doing so could result in electric shock and serious injury or death.
■To prevent damage or fire
Make sure bulbs are fully seated and locked.
