●Check for and remove any excess ice or snow that may have
accumulated on the exterior lights, vehicle's roof, chassis,
around the tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes
before getting in the vehicle.
● If a door is opened and closed when its side window is frozen,
the window safety device will operate and the side window
open/close function linked to door operation may not operate
correctly. If this occurs, perform the following after the ice has
melted.
Open the side window until it is approximately halfway open
with the door closed.
Fully close the window by pulling the switch up to the one-
touch closing position and continue holding the switch for 1
second or more after the window fully closes.
The window position is reset and the safety device operations will
be released.
■When driving the vehicle
Accelerate the vehicle slowly, keep a safe distance between you
and the vehicle ahead, and drive at a reduced speed suitable to
road conditions.
■ When parking the vehicle (in the winter time or in the cold
latitudes)
Park the vehicle and move the select lever to P (automatic trans-
mission) or shift lever to 1 or R (manual transmission) without
setting the parking brake. The parking brake may freeze up, pre-
venting it from being released. If necessary, block the wheels to
prevent inadvertent sliding or creeping.

■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.

WARNING
■
When washing the vehicle
● Do not wash the engine compartment and area adjacent to it. If water
enters the engine air intake or electrical parts it will cause engine trouble or
a malfunction of the power steering.
● When washing the vehicle, the brakes may get wet. As a result, the brake
stopping distance will be longer. To dry the brakes, drive the vehicle at a
safe speed while lightly depressing the brake pedal to heat up the brakes.
● When washing inner fenders, underbody, bumpers and protruding objects
such as exhaust pipes and exhaust finishers, be careful to prevent injuries
from contacting sharp ends.
■ Precautions regarding the exhaust pipes
Exhaust gasses cause the exhaust pipes and rear bumper diffusers to
become quite hot.
When washing the vehicle, be careful not to touch the pipes and diffusers
until they have cooled sufficiently, as touching hot exhaust pipes and rear
bumper diffusers can cause burns.

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.

SUBARU warranties do not cover any part of the vehicle which is damaged
by adding or applying chemicals and/or solvents other than those approved
or recommended by SUBARU.

Adding fluid
Make sure to check the fluid type and prepare the necessary items.
Fluid type
FMVSS No.116 DOT 3 or DOT 4 brake fluid
ItemsClean funnel
■ Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
WARNING
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets in your eyes, flush your eyes with clean water immediately.
If you still experience discomfort, see a doctor.
CAUTION
■ If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.
