Front passenger occupant detection system
Your vehicle is equipped with a front passenger occupant detection
system. Using the sensors installed under the seat cover, the system
detects the conditions of the front passenger seat and activates or
deactivates the frontal airbag for front passenger seat. The occupant
detection system may not inflate the front passenger’s SRS frontal
airbag even when the driver’s SRS frontal airbag deploys. This is not
a malfunction. If the seatbelt buckle switch and/or front passenger’s
occupant detection system have fa iled, the SRS airbag system warn-
ing light will illuminate. Have the system inspected by your SUBARU
dealer immediately if the SRS ai rbag system warning light illumi-
nates.
If your vehicle has sustained impact , this may affect the proper func-
tion of the SUBARU advanced front al airbag system. Immediately
contact your SUBARU dealer a nd have your vehicle inspected. Do
not use the front passenger seat while driving to your SUBARU
dealer.

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.

■
Low fuel level warning light
When the vehicle is on an incline, curve and so forth, the fuel inside the tank
moves, which may cause the warning light to come on early.
■ Front passenger detection sensor and passenger seatbelt reminder
and warning buzzer
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and warning
buzzer to sound, even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■
When the tire pressure warning light comes on (if equipped)
Check the tire inflation pressure and adjust to the appropriate level.
■The tire pressure warning light may turn on due to natural causes
(if equipped)
The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire (vehicles with a tire pres-
sure monitoring system)
The compact spare tire is not equipped with a tire pressure warning
valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire has been replaced with the spare
tire. Replace the spare tire with the repaired tire and adjust the tire infla-
tion pressure. The tire pressure warning light will go off after a few min-
utes.
