1-6. Security system
Engine immobilizer system
The vehicle's keys have built-in transponder chips that prevent the
engine from starting if the key has not been previously registered in
the vehicle's on-board computer.
Never leave the keys inside the vehicle when you leave the vehicle.
This system is designed to help prevent vehicle theft but does not
guarantee absolute security against all vehicle thefts.
Vehicles without a keyless
access with push button
start system
The indicator light flashes after
the key has been removed
from the engine switch to indi-
cate that the system is operat-
ing.
The indicator light stops flash-
ing after the registered key
has been inserted into the
engine switch to indicate that
the system has been can-
celed.

WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS airbag system warn-
ing light not come on when you start the engine, this could mean that these
systems are not available to help protect you in an accident, which could
result in death or serious injury. Have the vehicle inspected by your
SUBARU dealer immediately if this occurs.
*4
: Vehicles without a keyless access with push button start sys- tem
These lights turn on when the engine switch is turned to the “ON”
position to indicate that a system check is being performed. They
will turn off after the engine is started. There may be a malfunction
in a system if a light does not come on, or if the lights do not turn off.
Have the vehicle inspected by your SUBARU dealer for details.
Vehicles with a keyless access with push button start system
These lights turn on when the push-button ignition switch is turned
to “ON” mode to indicate that a system check is being performed.
They will turn off after the engine is started. There may be a mal-
function in a system if a light does not come on, or if the lights do
not turn off. Have the vehicle inspected by your SUBARU dealer for
details.

When driving
Driving assist systems
When the TRAC/Vehicle stability control (VSC) systems are operating
The slip indicator light will flash
while the TRAC (brake LSD
function)/Vehicle stability control
(VSC) systems are operating.
To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
■Vehicle stability control (VSC)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
■TRAC (Traction Control)
Helps to maintain drive power and pr event the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads.
The TRAC system is also equipped with the brake LSD function.
■Electric power steering
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

When driving
■Turning off both TRAC and Vehicle stability control (VSC) systems
To turn the TRAC and Vehicle stability control (VSC) systems off, press and
hold for more than 3 seconds while the vehicle is stopped.
The Traction Control System OFF indicator light and the Vehicle stability
control (VSC) off indicator light will come on.
In this case, the brake LSD function remains on.
Press the button again to turn the systems back on.
■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 Vehicle stability control (VSC) SPORT mode
Vehicles without a keyless access with push button start system
When the engine switch is turned to “LOC K” position after driving in Vehicle
stability control (VSC) SPORT mode, the mode is automatically deactivated.
Vehicles with a keyless access with push button start system
When the push-button ignition switch is turned off after driving in Vehicle sta-
bility control (VSC) SPORT mode, the mode is automatically deactivated.
■Sounds and vibrations caused by the ABS, brake assist, TRAC and
Vehicle stability control (VSC) systems
●A sound may be heard from the engi ne compartment when the brake
pedal is depressed repeatedly, when the engine is started or just after the
vehicle begins to move. This sound does not indicate that a malfunction
has occurred in any of these systems.

When driving
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 control (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.

Maintenance and care
■Adding fluid
Make sure to check the fluid type and prepare the necessary items.
Fluid typeFMVSS No.116 fresh 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.
