Daytime running light system
● The daytime running lights illuminate using the same lights as the parking
lights and illuminate brighter than the parking lights.
● To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designed for use
at night.)
• The engine is running
• The select lever is shifted out of P (Vehicles with an automatic trans-
mission)
• The parking brake is released
• The headlight switch is off or in the “AUTO”
* position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate even if the parking
brake is set again.
● When the turn signal indicators are flashing, the daytime running light on
the side that the turn signals are flashing will turn off.
● When the hazard warning flashers ar e flashing, both daytime running
lights will turn off.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help
improve fuel economy.
■ Headlight control sensor
Headlight control sensor is located on the
passenger's side.
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

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.
Disabling the TRAC system
If 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.

“TRACK” mode
Your vehicle is equipped with two types of control modes to accom-
modate various driving preferences. The control modes can be
selected with the “TRACK” switch. Normal mode allows secure and
smooth normal driving. When the switch is pressed and held for 1
second or more, “TRACK” mode is activated. Control characteristics
such as the Vehicle stability control (VSC) and TRAC are adjusted to
afford maneuverability closer to what a driver may desire, while a
sense of security is retained. “TRACK” mode/Normal mode
The “TRACK” indicator and Vehi-
cle stability control (VSC) off indi-
cator come on when in “TRACK”
mode.
To change back to normal mode
while in “TRACK” mode, press
or the “TRACK” switch.
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 sta-
bility control (VSC) off indicator light will come on.
However, on vehicles with an automatic transmission, the brake LSD
function will remain 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 “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
When the push-button ignition switch is turned off after driving in “TRACK”
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.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.

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.

■ 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.
■ The system may be malfunctioning when
In the following situations, the system may be malfunctioning. Have the vehi-
cle inspected by your SUBARU dealer.
● The slip indicator is illuminated.
● The hill start assist ON indicator turns off and a buzzer sounds.
