High/low beam change (dim- mer)

High beam

Low beam

When the headlights are on high beam, the high beam indicator light “ ” on the combination meter is also on.

Headlight flasher

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.

When the headlights are on high beam, the high beam indicator light “ ” on the combination meter also illuminates.

NOTE

The high beam assist function uti- lizes the stereo camera installed at the position of the front map lights.

For details on how to handle the stereo camera, refer to the Owner’s Manual supplement for the EyeSight system.

The high beam assist function automati- cally changes the headlight from high beam to low beam (or vice versa).

When all of the following conditions are met, the headlight will change to high beam.

When the vehicle speed increases to or above 20 mph (32 km/h).

There is no preceding or oncoming vehicle.

When the forward area of the vehicle is bright.

When there is a preceding or oncoming vehicle.

When the EyeSight system is malfunc- tioning or is temporarily stopped.

Do not overestimate the capacity of the high beam assist function. The driver always has the responsibility to understand the surrounding situation, to drive safely, and to change the headlight mode manually if necessary.

The factory setting (default setting) for this function is set as “operational”. This setting can be changed to OFF (non-operation) at SUBARU dealers. For more details, contact a SUBARU dealer.

The high beam assist function will be activated when all the following conditions are met.

The light control switch is in the “AUTO” position and the low beam headlights are on automatically.

The turn signal lever is pushed forward.

High beam assist indicator light

When the high beam assist function is activated, the high beam assist indicator light on the combination meter will illumi- nate.

The sensitivity of the high beam assist function can be lowered by performing the following operations.

Before turning the ignition switch to the “ON” position, set the light control switch to the “AUTO” position and push the signal lever forward (high beam position).

Turn the ignition switch to the “ON” position and within approximately 15 sec- onds, press the “ / ” (following distance setting) switch more than 10 times con- secutively.

When the sensitivity of the high beam assist function is lowered, the high beam assist indicator light “” on the combina- tion meter will flash.

The sensitivity of the high beam assist function cannot be lowered in the following conditions.

Cruise control or Adaptive Cruise Control indicator is illuminated

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.

At this time, the high beam assist function will turn off, the high beam assist indicator light will turn off and the high beam indicator light will turn on.

After manually changing the head- light mode to the high beam, if you turn on the high beam assist function, return the light control switch to the “AUTO” position.

When manually changing the head- light mode to the high beam, if you turn the light control switch to the “ ” position, the instrument panel illumina-

tion, parking lights, front side marker lights, rear side marker lights, tail lights and license plate lights will be on.

! Tips for the high beam assist sys- tem

The high beam assist function recog- nizes the conditions surrounding the ve- hicle based on the brightness of illumina- tion 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 or fogged

When the windshield is cracked or damaged

When the stereo camera is de- 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 or uneven surfaces

When driving on a road with many 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.

Color or brightness of the headlights of an oncoming vehicle or the tail lights of a vehicle ahead

The headlights of the oncoming vehicle or the tail lights of the vehicle ahead are covered with mud, snow, etc.

Movement and direction of an on- coming vehicle or a vehicle ahead

When the headlights of an oncom- ing vehicle or the tail lights of a vehicle ahead illuminate on only one side

When the oncoming vehicle or vehicle ahead is a motorcycle

Conditions of a road (slope, curve, road surface, etc.)

Number of passengers and weight of loaded cargo

Limitation of the detection ability of the stereo camera

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.

Instruments and controls/Steering Responsive Headlight (SRH) 3-71
