WARNING
■SRS airbag precautions
●Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbag has deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garni shes, are damaged or cracked, have
them replaced by your SUBARU dealer.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your SUBARU dealer.
The SRS airbags may malfunction or deploy (inflate) accidentally, causing
death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags.
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear

WARNING
■Front passenger occupant detection system precautions
●Never install a rearward facing child seat in the front passenger’s seat
even if the front passenger’s SRS frontal airbag is deactivated. Be sure to
install it in the rear seat in a correct manner. Also, it is strongly recom-
mended that any forward facing child seat or booster seat be installed in
the rear seat, and that even children who have outgrown a child restraint
system be also seated in the rear seat. This is because children sitting in
the front passenger’s seat may be killed or severely injured should the
front passenger’s SRS frontal airbag deploy. SUBARU believes that the
rear seats are the safest place for children
● If luggage or electronic devices are placed on the front passenger seat,
the OFF indicator may turn off and the ON indicator may illuminate. If this
occurs, the front passenger’s airbag may deploy during a collision. If this is
not desirable, remove the luggage or el ectronic devices from the front pas-
senger seat.
● Modifications for persons wi th disabilities that may affect the front passen-
ger occupant detection system. (U.S. onl y) Removing, replacing or modify-
ing any parts of the front seats, seatbelts, front bumper, front side frame,
instrument panel, combination meter, steering wheel, steering column,
tires, suspension or floor panel can affect the operation of the SUBARU
front passenger occupant detection system.

WARNING
■
TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ When the Vehicle stability control (VSC) and/or brake LSD function is
activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/Vehicle stability co ntrol (VSC) systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/Vehicle stability control (VSC) systems off
unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and Vehicle stability cont rol (VSC) systems will not function
correctly if different tires are installed on the vehicle.
Contact your SUBARU dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension

■Brake (vehicles with brembo brake)
●Painted brake calipers
• When using detergent, use neutral detergent. Do not use hard brushes
or abrasive cleaners, as they will damage the paint.
• Do not use detergent on the brake calipers when they are hot.
• Wash detergent off immediately after use.
● Rust may form if the vehicle is parked with wet brake pads or disc rotors,
causing them to stick. Before parking the vehicle after it is washed, drive
slowly and apply the brakes several times to dry the parts.
■ CFRP (Carbon Fiber Reinforced Plastic) part (if equipped)
●Remove any dirt using a neutral detergent. Do not use hard brushes or
abrasive cleaners. Do not use st rong or harsh chemical cleaners.
● As the CFRP parts may change color if they are exposed to ultraviolet
rays for extended periods of time, SUBARU recommends that your vehi-
cle be stored in a place where it will not be exposed to direct sunlight.
● Do not use wax that contains abrasives.
■ When washing the vehicle
Wear rubber gloves and use a hand brush when washing down underbody,
inner fenders and suspension to effectively remove mud and dirt off.

cover), connectors or the following parts. The parts may be damaged if they
come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
■ Cleaning the rear bumper cherry red stripe (tS models)
● When using a high pressure car wash (pressure washer) to wash your
vehicle, keep the nozzle a safe distance (11.9 in. [30 cm] or more) from the
stripe. Do not use the high pressure car wash on the same area continu-
ously.
● When using a heated or steam high pressure car wash or extra high-pres-
sure pressure washer, do not point the nozzle directly at the stripe, other-
wise the stripe may come off or be damaged.
● Carefully read the label of a car wash soap before using it, as some car
wash soaps may adversely affect the adhesion strength of the stripe.
● If dirt cannot be removed from the stripe, clean it off using a soft cloth
dampened with a neutral detergent diluted with water.
■ Avoiding damage to the under spoilers (tS models)
● When cleaning the under spoilers, do not use organic substances such as
gasoline, paint thinner, acidic or alkaline solutions, or other detergent.
● The under spoilers may deform if exposed to high temperatures or
extreme heat.
