High Beam Assist (HBA)
Optionally available with some 2017MY Subaru vehicles, the High Beam Assist (HBA) system
is designed to increase the use of the vehicle’s High Beam headlights to improve low ambient
light visibility. This is accomplished by automatically switching the headlights between high
and low beam according to the conditions in front of the vehicle. The HBA system provides the
following benefits to the driver:
• Reduced operation of the headlight switch
• Prevents driver from forgetting to turn off the high beams
• Improves EyeSight® recognition during nighttime driving

Caution: 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.
