High performance driving
precautions
WARNING
High performance driving is inher-
ently dangerous. It should be per-
formed only on a closed, super-
vised course by drivers with ade-
quate skill and experience. High
performance driving should never
be performed on public roads.
When driving on public roads, al-
ways obey posted speed limits and
other applicable laws. Failure to
follow these warnings, and the
steps outlined below, may result in
serious injury or death.
CAUTION
High performance driving presents
a high risk of damage to your
vehicle and its component parts. It
requires additional maintenance
and vehicle preparation, and should
be performed only by drivers with
adequate skill and experience. Fail-
ure to follow the steps outlined
below may result in significant
damage to your vehicle. Addition-
ally, your vehicle warranties do not
cover damage that results from
high performance driving.
Precautions for high performance driv-
ing are listed as follows. However, the
listed precautions are minimum re-
quirements and additional measures
may be necessary to ensure safety. It
is the owner's responsibility to main-
tain the vehicle in its optimum condi-
tion and acknowledge the risk of high
performance driving.
& Before driving
1. Inspect the remaining brake pad thick-
ness and replace them if they are 6 mm or
less. Consult your SUBARU dealer for
replacement.
2. Prior to high performance driving,
check the brake related parts. If changing
the brake fluid to a high performance
brake fluid, use an Ethylene glycol based
brake fluid equivalent to genuine brake
fluid. Do not use silicone based fluids.
When a high performance fluid is used,
check the brake related parts and perform
an inspection frequently, including the
brake hoses. These parts may be ex-
posed to heat from high performance
driving.
Change the fluid to genuine DOT3 fluid or
DOT4 fluid after high performance driving.
3. If new brake pads have been fitted,
prior to high performance driving, perform
a brake quenching to achieve immediate
and constant deceleration when braking
at high speeds. Regarding brake quench-
ing, refer to the following steps. Drive the
vehicle for approximately 50 miles (80
km) while avoiding excessive acceleration
and sudden braking. Then drive the
vehicle for approximately 50 more miles
(80 km) to burnish the brake pads. To
burnish the brake pads, gradually in-
crease the vehicle speed and apply
strong braking.
4. The power steering fluid level is
recommended to be maintained at "HOT
MIN" due to the thermal expansion of the
fluid when heated up. Refer to the vehicle
Owner's Manual for details.
5. To improve engine cooling in high
ambient temperatures, the undercover
may be removed to increase the engine
cooling efficiency. Consult your SUBARU
dealer for details.
6. Make sure that the cooling vents/
ducts, intercooler and the radiator are
free of blockage.
