334 4-1. Maintenance and care
BRZ_U
■Parts containing resin such as the bumper
Do not scrub with abrasive cleaners.
■ 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.
■ 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 electric al 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, under body, 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.

vents which have not been tested or approved by SUBARU.
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.

Radiator and condenser
Check the radiator and condenser and clear away any foreign
objects.
If either of the above parts are extremely dirty or you are not sure of
their condition, have your vehicle checked by your SUBARU dealer.
Brake fluid■ Checking fluid level
The brake fluid level should be
between the “MAX” and “MIN”
lines on the tank.
“MAX”
“MIN”
WARNING
■When the engine is hot
Do not touch the radiator or condenser as they may be hot and cause seri-
ous injuries, such as burns.

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.

5-1. Essential information

If your vehicle needs to be towed
Emergency towingIf a tow truck is not available in an emergency, your vehicle may be
temporarily towed using a cable or chain secured to the emergency
towing eyelet to move the vehicle to a safe location or to free a stuck
vehicle from sand or snow. This should only be attempted on hard
surfaced roads for short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
vehicle's wheels, drive train, axles, steering and brakes must be in
good condition.
For vehicles with an automatic transmission, only the front towing
eyelet may be used. Towing eyelet
If towing is necessary, we recommend having your vehicle towed by
your SUBARU dealer or a comme rcial towing service, using a flat
bed truck.
The vehicle must be secured properly with safety chains. Each
safety chain should be equally tightened and care must be taken not
to pull the chains so tightly that the suspension bottoms out.

414 5-1. Essential information
BRZ_U
■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.
