Automatic car washes
● Fold the mirrors before washing the vehicle. Start washing from the front
of the vehicle. Make sure to and extend the mirrors before driving.
● When having your vehicle washed in an automatic car wash, make sure
beforehand that the car wash is of suitable type to avoid scratches to the
vehicle surface and harm to your vehicle’s paint.
● Vehicles with a rear spoiler: In certain automatic car washes, the rear
spoiler may interfere with machine operation. This may prevent the vehi-
cle from being cleaned properly or result in damage to the rear spoiler.
● Vehicles with CFRP (Carbon Fiber Reinforced Plastic) parts: Do not use
automatic car washes as they may damage the rear wing or its finish.
■ High pressure car washes
● Do not allow the nozzles of the car wash to come within close proximity
of the windows and door frames as water may enter the cabin.
● Before using the car wash, check that the fuel filler lid on your vehicle is
closed properly.
■ Alloy wheels
● Remove any dirt immediately by using a neutral detergent.
● Wash detergent off with water immediately after use.
● To protect the paint from damage, make sure to observe the following
precautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after
driving or parking in hot weather
■ Parts containing resin such as the bumper
Do not scrub with abrasive cleaners.

CAUTION
■
When using a high pressure car wash
Do not bring the nozzle tip close to boots (rubber or resin manufactured
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.

Engine coolantThe coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold. Reservoir cap
“FULL”
“LOW”
If the level is on or below the
“LOW” line, add coolant up to the
“FULL” line.
CAUTION
■To prevent serious engine damage
Check the oil level on a regular basis.
■ When replacing the engine oil
●Be careful not to spill engine oil on the vehicle components.
● Avoid overfilling, or the engine could be damaged.
● Check the oil level on the dipstick every time you fill the oil.
● Be sure the engine oil filler cap is properly tightened.
■If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant filler cap, radiator cap,
drain cock and water pump.
If you cannot find a leak, have your SUBARU dealer pressure test the cap
and check for leaks in the cooling system.

■When replacing wheels (vehicles with a tire pressure monitoring
system)
The wheels of your SUBARU are equipped with tire pressure warning
valves and transmitters that allow the tire pressure monitoring system to
provide advanced warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, the tire pressure warning valves and
transmitters must be installed. (
→P. 375)
WARNING
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may result in loss of handling control.
●Never use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.
■When installing the wheel nuts
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing an
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
●Be sure to install the wheel nuts with
the tapered ends facing inward.
Installing the nuts with the tapered
ends facing outward can cause the
wheel to break and eventually cause
the wheel to come off while driving,
which could lead to an accident
resulting in death or serious injury.
