Automatic reactivation of TRAC and Vehicle stability control (VSC) sys-
tems
After turning the TRAC and Vehicle stability control (VSC) systems off, the
systems will be automatically reactivated in the following situations:
● Vehicles without a keyless access with push button start system: When
the engine switch is turned to “LOCK” position
● Vehicles with a keyless access with push button start system: When the
push-button ignition switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed is more than approximately 31 mph (50 km/h).
If both the TRAC and Vehicle stability control (VSC) systems are turned
off, automatic reactivation will not occur when vehicle speed increases.
■ Automatic deactivation of “TRACK” mode
Vehicles without a keyless access with push button start system
When the engine switch is turned to “LOCK” position after driving in
“TRACK” mode, the mode is automatically deactivated.
Vehicles with a keyless access with push button start system

WARNING
■
TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ When the Vehicle stability control (VSC) and/or brake LSD function is
activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/Vehicle stability co ntrol (VSC) systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/Vehicle stability control (VSC) systems off
unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and Vehicle stability cont rol (VSC) systems will not function
correctly if different tires are installed on the vehicle.
Contact your SUBARU dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Hill star t assist
The hill start assist system helps to maintain braking force to assist
starting off forward while facing uphill or starting off backward while
facing downhill. As the hill start assist system is initially disabled,
enable the system to make it oper able. The enabled/disabled setting
will be maintained the next time the engine is started.
When the system is enabled,
the hill start assist ON indica-
tor will be illuminated.
■ Enabling the hill start assist system
Park your vehicle in a flat, safe location.
Make sure that the parking brake is securely engaged.
Stop the engine by turning the engine switch to the “LOCK”
position (vehicles without a keyless access with push but-
ton start system) or turning the push-button ignition switch
off (vehicles with a keyless access with push button start
system).
Start the engine and check that the ABS warning light and
slip indicator are off.
Press and hold for
approximately 30 seconds.
Check that both the Vehicle
stability control (VSC) off indi-
cator and Traction Control Sys-
tem OFF indicator illuminate
and then turn off.

button ignition switch is turned to “ACC” mode or turned off.
■ Notes for the hill start assist system
● A slight jolt may be felt when starting off backward with the select lever in
R (vehicles with an automatic transmission) or the shift lever in R (vehi-
cles with a manual transmission) and then moving forward.
● If the braking power of the hill start assist system is insufficient, depress
the brake pedal.
● While the vehicle is stopped, make sure to depress the brake pedal.

●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.

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.
