Light control switch
CAUTION
.Use of any lights for a long period
of time while the engine is not
running can cause the battery to
discharge.
.Before leaving the vehicle, make
sure that the lights are turned off.
If the vehicle is left unattended
for a long time with the lights
illuminated, the battery may be
discharged.
Models with“keyless access with
push-button start system”:
The light control switch operates when the
push-button ignition switch is in the“ACC”
or“ON”position.
Regardless of the position of the light
control switch, the illuminated lights are
turned off when the push-button ignition
switch is turned off.
Models without“keyless access with
push-button start system”:
The light control switch operates when the
key is inserted in the ignition switch.
Regardless of the position of the light
control switch, the illuminated lights areturned off when the key is removed from
the ignition switch.
NOTEThe light control switch can be oper-
ated (except auto on/off headlights),
even under the following conditions.
.when the push-button ignition
switch is turned off (models with“key-
less access with push-button start
system”)
.when the key is not inserted into the
ignition switch (models without“key-
less access with push-button start

NOTE.You cannot lower the sensitivity of
the high beam assist function in the
following conditions.
–Cruise control or Adaptive Cruise
Control is in operation
–The EyeSight warning indicator
(yellow) is illuminated
.The sensitivity of the high beam
assist function returns to normal level
the next time the ignition switch is
turned to the“LOCK”/“OFF”position
and the engine is restarted.
!How to change the headlight
mode manually
Change to the low beam:
Return the turn signal lever to the center
position to turn off the high beam assist
function. Then the high beam assist
indicator will turn off.
Change to the high beam:
Turn the light control switch to the“
”
position to change the headlight mode to
the high beam.
At this time, the high beam assist function
will turn off, the high beam assist indicator
will turn off and the high beam indicator
light will turn on.
NOTEAfter manually selecting the high beam
mode:
.If you want to turn on the high beam
assist function, return the light control
switch to the“AUTO”position.
.Turn the light control switch to the
“
”position to turn on the instrument
panel illumination, parking lights, front
side marker lights, rear side marker
lights, tail lights and license plate
lights.
!Tips for the high beam assist
function
.The high beam assist function recog-
nizes the condition surrounding the vehicle
based on the brightness of illumination
ahead of your vehicle, etc. Therefore, the
headlight mode may switch in some
situations that do not match to the driver’s
sense.
.A bicycle or cargo cycle may not be
detected.
.Under the following situations, the high
beam assist function may not work prop-
erly. As a result, the glare of the high beam
may disturb the oncoming vehicle or
vehicle ahead. Also, the low beam mode
may continue although there are no
oncoming vehicles and vehicles ahead.In the such cases, change the headlight
mode manually.
–In bad weather (fog, snow, sand
storm, heavy rain, etc.)
–When the windshield glass is dirty,
fogged, cracked or damaged
–Whenthestereocameraisde-
formed or the stereo camera lenses
are dirty
–If there are lights similar to the
headlights or the tail lights in the
surrounding area
–When an oncoming vehicle or ve-
hicle ahead is driven without its head-
lights and tail lights on
–If the headlights of an oncoming
vehicle or the tail lights of a vehicle
ahead are dirty or discolored, or if the
light beams are not aimed correctly
–When a rapid change of brightness
continues while driving
–When driving on a road with many
ups and downs, uneven surfaces or
curves
–When there are some objects that
reflect light strongly, such as a road
sign or a mirror in vehicle ahead
–When the rear part of the vehicle
ahead, such as a container, reflects
light strongly
–When the headlights of your vehicle
are damaged or dirty

–When your vehicle is tilted, such as
in case the vehicle has a flat tire or is
being towed
–Immediately after the engine has
started
.In the following conditions, the head-
light mode will not be automatically chan-
ged from the high beam to the low beam.
–When your vehicle passes an on-
coming vehicle suddenly in a blind
curve
–When another vehicle passes in
front of your vehicle
–When an oncoming vehicle or ve-
hicle ahead comes in and out of view
because of continuous curves, median
strips, roadside trees, etc.
.If the stereo camera detects the light of
the front fog lights of an oncoming vehicle,
the headlight mode may change from the
high beam to the low beam automatically.
.The headlight mode may change from
the high beam to the low beam, or the low
beam mode may continue, when affected
by a street light, traffic signal, illumination
of an advertisement board, or a reflective
object such as a road sign and signboard.
.The timing of the change of headlight
mode may differ due to the following
factors.
–the vehicle condition (e.g., the num-
ber of passengers or the weight ofloaded cargo)
–surrounding situation (e.g., the
movement and direction of an oncom-
ing vehicle or vehicle ahead)
–detection limitations of the camera
angle
&Headlight flasher
CAUTION
Do not hold the lever in the flashing
position for more than just a few
seconds.
To flash the headlights, pull the lever
toward you and then release it. The high
beam will stay on for as long as you hold
the lever. The headlight flasher works even
though the lighting switch is in the“
”(off)
position.
When the headlights are on high beam, the
high beam indicator light“
”on the
combination meter is also on.

&Daytime running light system
WARNING
When the daytime running lights are
illuminated, the tail lights do not
illuminate. When it becomes dark
outside, turn the light switch to the
“
”position to illuminate the head-
lights and tail lights. This will im-
prove visibility and allow other dri-
vers to see your vehicle more easily.
The daytime running lights will automati-
cally illuminate when the following condi-
tions are fulfilled.
.The engine is running.
.The parking brake is fully released.
.The light control switch is in the“AUTO”
(if equipped),“
”or off position.
.For CVT models, the select lever is in a
position other than the“P”position.
NOTEWhen the light switch is in the“
”
position, the instrument panel illumina-
tion, front side marker lights, tail lights
and license plate lights are also illumi-
nated.
Steering Responsive Head-
light (SRH) (if equipped)1) The target area of illumination when SRH
is activated
2) The target area of illumination when SRH
is not activatedSRH is a function that automatically moves
the headlight beam to the left or right in
accordance with the steering angle and
vehicle speed. This function helps to
improve the visibility at night by illuminat-
ing the road ahead at corners and inter-
sections.NOTESRH only activates when the vehicle is
traveling forward at the speed of ap-
proximately 5 mph (8 km/h) and over.
&To turn on/off the SRHOperate the combination meter display
(color LCD) to turn on/off the SRH. For
details, refer to“SRH”F3-43.SRH OFF indicatorThe SRH OFF indicator on the combina-
tion meter turns off when SRH is turned on.
The SRH OFF indicator on the combina-
tion meter illuminates when SRH is turned
off.
If SRH is malfunctioning, a message
appears on the warning screen when the
ignition switch is in the“ON”position. It
indicates that SRH has been deactivated.
Contact a SUBARU dealer for an inspec-
tion.

a small amount of air may flow from the
foot outlets when ventilation mode is
displayed.
.If you operate any of the buttons on
the control panel other than the“OFF”
button, rear window defogger button
and temperature control dial(s) during
FULL AUTO mode operation, the

outside conditions are no longer
dusty.NOTEWhen the battery is disconnected or the
battery voltage drops, the air inlet
selection operation indicator light may
blink. This does not indicate a malfunc-
tion. However, if the indicator light
blinks every time you start the engine,
a malfunction may occur in the elec-
trical circuit. Have the vehicle in-
spected at the nearest SUBARU dealer.
