BRZ_U (A4450BE-A)
CAUTION
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
● On vehicles with an automatic transmission, do not race the engine for
more than 5 seconds in any position except the N or P position when the
brake is applied or when chocks are used in the wheels. This may cause
the transmission fluid to overheat.
■ Avoiding damage to the under spoilers (tS models)
On vehicles with under spoilers, be careful when driving, as the ground
clearance will be lower than a vehicle without them as follows:
●Front under spoiler: Ground clearance at the front of each front wheel arch
and the center of the front bumper is lower by approximately 0.4 in. (1 cm)
and 1.6 in. (4 cm), respectively.
● Side under spoilers: Ground clearance at the sides of the vehicle is lower
by approximately 1.2 in. (3 cm).
● Rear under spoilers: Ground clearance at each corner of the rear bumper
is lower by approximately 0.4 in. (1 cm).
■ Replacement of brake pad and lining
If you continue to drive despite the scraping noise from the audible brake
pad wear indicator, it will result in the need for costly brake rotor repair or
replacement.
■ Breaking-in of new brake pads and linings
Pulling the parking brake lever too forcefully may cause the rear wheels to
lock. To avoid this, be certain to pull the lever up slowly and gently.

CAUTION
■
If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehicle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( →P. 457)
■ When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your SUBARU dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, trans-
mission, differential, etc.
● Lubricant condition for the propeller shaft, bearings and suspension joints
(where possible) and the function of all joints, bearings, etc.

Exclusive content for BRZ ( )■ G-force
Displays lateral G-forces on the vehicle
Also displays, around the periphery of the G-force display, the left and
right steering amount, accelerator pedal input, and brake fluid pres-
sure
Record of the maximum G-
forces
Accelerator pedal input
Brake fluid pressure
Steering amount
If the steering wheel is turned
completely to the left or right, the
bottom side of the gauge on the
corresponding side will be illumi-
nated in red.
This display is intended for use as a guideline. Depending on factors such
as the road surface condition, temperature and vehicle speed, the display
may not show the actual condition of the vehicle.
● Resetting the record of maximum G-forces
Press and hold to reset the record.
● Changing the acceleration G-force display range
Press and hold to change the range of the acceleration G-
force display between 1.0 G and 0.5 G.
● Screen displayed while driving
While driving, the G-force screen will automatically be changed
to the power and torque curve display. To display the G-force
screen, stop the vehicle in a safe place.

G-force display
● Depending on the vehicle usage conditions , the brake fluid pressure dis-
play may not reach its maximum reading even though the brake pedal is
fully depressed.
● If a battery terminal is disconnected and reconnected, the steering
amount display may be disabled temporarily. After driving the vehicle for
a while, the display will be enabled.
■ Suspension of the settings display
● The settings cannot be changed while driving. When changing settings,
park the vehicle in a safe place.
● If a warning message is displayed, operation of the settings display will
be suspended.
■ Using the stopwatch
If the engine is stopped while the stopwatch is operating, the stopwatch will
stop and the time up to that point will be recorded.
■ Outside temperature display
● In the following situations, the correct outside temperature may not be
displayed.
• When the vehicle is very hot, such as when under the sun.
• When the vehicle is idling or being driven at low speeds such as in a
traffic jam or when the engine is stopped and then restarted immedi-
ately afterward.
• When the actual outside temperature is outside of the indicator range.
● If “ − − ” is displayed for approximately 1 minute or more or if the outside
temperature is not displayed, the system may be malfunctioning. Have
the vehicle inspected by your SUBARU dealer.
■ Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.

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.

■
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.
