132 1-7. Safety information
BRZ_U (A4450BE-A)
The front passenger’s frontal airbag ON and OFF indicators show
you the status of the front passenger’s SRS frontal airbag. When
the engine switch is turned to the “ON” position, (vehicles without a
keyless access with push button start system), or the push-button
ignition switch is turned to “ON” mode (vehicles with a keyless
access with push button start system), both the ON and OFF indi-
cators illuminate for 6 seconds during the system check. After the
system check, both the ON and OFF indicators turn off for 2 sec-
onds. Then, either the ON or OFF indicator illuminates depending
on the condition of the front passenger’s frontal airbag.
When the OFF indicator remains off and ON indicator illuminates,
the front passenger’s frontal airbag may deploy during a collision.
When the OFF indicator illuminates and ON indicator remains off,
the front passenger’s frontal airbag does not deploy during a colli-
sion.
If the front passenger’s frontal airbag ON and OFF indicators
remain on when the engine switch is turned to the “ON” position
(vehicles without a keyless access with push button start system)
or the push-button ignition switch is turned to “ON” mode (vehicles
with a keyless access with push button start system), or the indica-
tors remain off after the system check, the system may be malfunc-
tioning. Have the vehicle inspected by your SUBARU dealer
immediately.
After that, one of the indicators illuminates depending on the status
of the front passenger’s SRS frontal airbag determined by the
SUBARU advanced frontal airbag monitoring system.

Turn the engine switch to the “ON” position (vehicles without a
keyless access with push button start system), or the push-
button ignition switch to “ON” mode (vehicles with a keyless
access with push button start system). The ON and OFF indi-
cators illuminate for 6 seconds during the system check and
after the system check is performed, the ON and OFF indica-
tors turn off for 2 seconds. Then, the OFF indicator remains
off while the ON indicator is illuminated. If the ON indicator
remains off and the OFF indicator is illuminated, move the
occupant to the rear seat backwards and immediately contact
your SUBARU dealer and have the vehicle inspected.
If the front passenger’s frontal airbag ON indicator illuminates and the OFF indicator turns off
even when an infant or a small child is in a child restraint system (including booster seat)
This can be caused by the child restraint system being installed incor-
rectly. Perform the following.
Vehicles without a keyless access with push button start sys-
tem:
The engine switch is turned to the “LOCK” position.
Vehicles with a keyless access with push button start system:
Turn the push-button ignition switch off.
Remove the child restraint system from the seat. By referring
to the child restraint manufacturer’s recommendations as well
as the child restraint system installation procedure in “child
restraint system”, correctly reinstall the child restraint system.

■
Engine speed while driving (vehicl es with an automatic transmission)
In the following conditions, the engine speed may become high while driving.
This is due to automatic up-shifting control or down-shifting implementation
to meet driving conditions. It does not indicate sudden acceleration.
● The vehicle is judged to be driving uphill or downhill
● When the accelerator pedal is released
● When driving on curves
● When the brake pedal is firmly depressed
■ New vehicle break-in driving (the first 1000 miles [1600 km])
The performance and long life of your vehicle are dependent on how you
handle and care for your vehicle while it is new. Follow these instructions
during the first 1000 miles (1600 km):
● Do not allow the engine speed to exceed 4000 rpm except in an emer-
gency.
● Do not drive at one constant engine or vehicle speed for a long time,
either fast or slow.
● Avoid starting suddenly and rapid acceleration, except in an emergency.
● Avoid hard braking, except in an emergency.
The same break-in procedures should be applied to an overhauled engine,
newly mounted engine or when brake pads or brake linings are replaced
with new ones.
■ Replacement of brake pad and lining
The front disc brake and the rear disc brake have audible wear indicators on
the brake pads. If the brake pads wear close to their service limit, the wear
indicator makes a very audible scraping noise when the brake pedal is
applied.
If you hear this scraping noise each time
you apply the brake pedal, have the
brake pads serviced by your SUBARU
dealer as soon as possible.
