■Before emergency towing
Release the parking brake.
Shift the select lever to N (vehicles with an automatic transmission)
or shift lever to neutral (vehicles with a manual transmission).
Vehicles without a keyless access with push button start system:
Turn the engine switch to the “A CC” (engine off) or “ON” (engine
running) position.
Vehicles with a keyless access with push button start system: Turn
the push-button ignition switch to “ACC” (engine off) or “ON”
(engine running) mode.
■ If towing a vehicle
Do not tow another vehicle. If towing a vehicle that has broken down is
unavoidable, avoid towing a vehicle that is heavier than your vehicle. Also,
do not pull out a vehicle that has fallen into a ditch.
WARNING
■Caution while towing
●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
● If the engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.

*1: Driver’s seatbelt buzzer:Vehicles without a keyless access with push button start system
The driver’s seatbelt buzzer sounds to alert the driver that his or her seatbelt
is not fastened. Once the engine switch is turned to the “ON” position, the
buzzer sounds for 6 seconds. If the vehicle reaches a speed of 12 mph (20
km/h), the buzzer sounds once. If the seatbelt is still unfastened after 24
seconds, the buzzer will sound intermittently for 10 seconds. Then, if the
seatbelt is still unfastened, the buzzer will sound in a different tone for 20
more seconds.
Vehicles with a keyless access with push button start system
The driver’s seatbelt buzzer sounds to alert the driver that his or her seatbelt
is not fastened. Once the
push-button ignition switch is turned to “ON”
mode
, the buzzer sounds for 6 seconds. If the vehicle reaches a speed of
12 mph (20 km/h), the buzzer sounds once. If the seatbelt is still unfastened
after 24 seconds, the buzzer will sound intermittently for 10 seconds. Then,
if the seatbelt is still unfastened, the buzzer will sound in a different tone for
20 more seconds.
*2: Front passenger’s seatbelt buzzer:
The front passenger’s seatbelt buzzer sounds to alert the front passenger
that his or her seatbelt is not fastened. The buzzer sounds once if the vehi-
cle reaches a speed of 12 mph (20 km/h). If the seatbelt is still unfastened

■If the tire pressure monitoring system is inoperative (if equipped)
The tire pressure monitoring system will be disabled in the following con-
ditions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmit-
ters are used.
●If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
●If the tire inflation pressure is 55 psi (380 kPa, 3.87 kgf/cm2 or bar) or
higher.
The tire pressure monitoring system may be disabled in the following
conditions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
●If non-genuine SUBARU wheels are used. (Even if you use SUBARU
wheels, the tire pressure monitoring system may not work properly
with some types of tires.)
●If tire chains are used.
●If a large metallic object which can interfere with signal reception is
put in the trunk.
■If the tire pressure warning light frequently comes on after blinking
for approximately one minute (if equipped)
If the tire pressure warning light frequently comes on after blinking for
approximately one minute when the push-button ignition switch is turned
to “ON” mode (vehicles with a keyless access with push button start sys-
tem) or the engine switch is turned to the “ON” position (vehicles without
a keyless access with push button start system), have it checked your
SUBARU dealer.
