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

Disabling the TRAC systemIf the vehicle gets stuck in mud, dirt or snow, the TRAC system may
reduce power from the engine to the wheels. Pressing to turn
the system off may make it easier for you to rock the vehicle in order
to free it.
In this case, the brake LSD function remains on. To turn the TRAC system off,
quickly press and release the
button.The Traction Control System OFF
indicator light will come on.
Press the button again to turn the
system back on.

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.

2-5. Driving information
●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.

Interior features
■The defoggers can be operated when
Vehicles without a keyless access with push button start system
The engine switch is in the “ON” position.
Vehicles with a keyless access with push button start system
The push-button ignition switch is in “ON” mode.
■The outside rear view mirror defoggers (vehicles with outside rear view
mirror defoggers)
Turning the rear window defogger on will turn the outside rear view mirror
defoggers on.
■When continuous operation is set (vehicles with an automatic air con-
ditioning system)
During continuous operation, the defogger stops operating for 2 minutes
after every 15 minutes of continual operation. Even during the 2 minutes that
operation stops, the operating light remains illuminated. The rear window
defogger will continue to operate in this cycle until it is turned off.
■Customization that can be configured at SUBARU dealer (vehicles with
an automatic air conditioning system)
The rear window defogger can be set to 15-minute operation or continuous
operation. (Customizable features →P. 445)
WARNING
■When the outside rear view mirror defoggers are on (vehicles with out-
side rear view mirror defoggers)
Do not touch the outside surface of the rear view mirrors, as they can
become very hot and burn you.
CAUTION
■To prevent battery discharge
Do not leave the rear window defogger on longer than necessary when the
engine is stopped.
