If you park your vehicle in
case of an emergencyUse the hazard warning flasher in day or
night to warn other drivers when you have
to park your vehicle under emergency
conditions.
Avoid stopping on the road. It is best to
safely pull off the road if a problem occurs.
You can activate the hazard warning
flasher regardless of the ignition switch
position.
Turn on the hazard warning by pushing the
hazard warning flasher switch. Turn it off
by pushing the switch again.
NOTEWhen the hazard warning flasher is on,
the turn signals do not work.
Temporary spare tire (if
equipped)
WARNING
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the tire pressure monitoring system
(TPMS) is unable to monitor all four
road wheels. Contact your SUBARU
dealer as soon as possible for tire
and sensor replacement and/or sys-
tem resetting.
CAUTION
.Never use any temporary spare
tire other than the original. Using
other sizes may result in severe
mechanical damage to the drive
train of your vehicle.
.Always conform to the following
instructions when using the tem-
porary spare tire. Otherwise, a
seriously dangerous situation

may occur.
The temporary spare tire is smaller and
lighter than a conventional tire and is
designed for emergency use only. Re-
move the temporary spare tire and re-
install the conventional tire as soon as
possible because the spare tire is de-
signed only for temporary use.
Check the inflation pressure of the tem-
porary spare tire periodically to keep the
tire ready for use. For the correct tire
pressure, refer to“Temporary spare tires”
F12-9.
When using the temporary spare tire, note
the following.
.Drive with caution when temporary
spare tire is fitted. Avoid hard acceleration
and braking, or fast cornering, as control of
the vehicle may be lost.
.Do not exceed 50 mph (80 km/h).
.Do not put a tire chain on the temporary
spare tire. Because of the smaller tire size,
a tire chain will not fit properly.
.Do not use two or more temporary
spare tires at the same time.
.Do not drive over obstacles. This tire
has a smaller diameter, so road clearance
is reduced.
1) Tread wear indicator bar
2) Indicator location mark.When the wear indicator appears on
the tread, replace the tire.
.The temporary spare tire must be used
only on a rear wheel. If a front wheel tire
gets punctured, replace the wheel with a
rear wheel and install the temporary spare
tire in place of the removed rear wheel.
.Always set the driver’s control center
differential to the manual mode and adjust
the initial LSD torque to the minimum.
Maintenance toolsYour vehicle is equipped with the following
maintenance tools.

WARNING
.Do not jack up the vehicle on an
incline or a loose road surface.
The jack can come out of the
jacking point or sink into the
ground and this can result in a
severe accident.

tools in the passenger compart-
ment after changing wheels. In a
sudden stop or collision, loose
equipment could strike occu-
pants and cause injury. Store
the tire and all tools in the proper
place..When you store a flat tire, be sure
to set the rear seatback to the
upright position. If you fold down
the seatback, an accident or
injury may occur when the flat
tire suddenly moves.
&Sealing flat tire (models with
flat tire repair kit)
WARNING
Read these instructions and
warnings carefully before sealing a
flat tire.
Compliance with these instructions
is vital to ensuring vehicle safety.
Noncompliance with these instruc-
tions means risking tire damage,
which can affect vehicle handling
and lead to loss of vehicle control.
This may result in serious injury or
death.
If the tire is punctured, you can seal the flat
tire temporarily by using the flat tire repair
kit. You can seal a flat tire caused, for
example, by nails or similar objects with
less than 0.2 in (4 mm). However, depend-
ing on the type and extent of tire damage,

北米Model "A1700BE-B" EDITED: 2017/ 10/ 11
some tires can only be partially sealed or
not sealed at all, and this condition may
cause a loss of tire pressure. A loss of tire
pressure can affect vehicle handling,
leading to the loss of vehicle control.
After sealing the flat tire temporarily,
change the tires with new ones as soon
as possible. We recommend that you have
the sealed tire changed by your nearest
SUBARU dealer. You may reuse the wheel
if the attached sealant is wiped off, but the
valve of the wheel must be replaced with a
new one. If you reuse the wheel without
replacing the valve, air may leak from the
valve.
For tire replacement, refer to“Tire replace-
ment”F11-36.!Safety precautions when sealing flat
tire
Observe the following rules when sealing a
flat tire.
1) Sealing is possible
2) Sealing is not possible
WARNING
.Do not use the flat tire repair kit in
the following cases.
–The tire has already been
damaged as a result of being
driven in the under inflated
condition.
–The tire damage is not located
within the visible tread of the
tire.–The tire damage is on the
sidewall of the tire.
–When the tire has been taken
off of the wheel.
–The wheel or the tire valve of
the flat tire is damaged.
–Two or more tires have been
punctured.
–The expiration date of the
sealant has passed.
–The tire is punctured by
pointed items such as nails
of 0.2 in (4 mm) or larger.
.When inflating the flat tire, if the
tire inflation pressure does not
reach the green zone of the
pressure gauge within 10 min-
utes, do not continue to seal the
tire. We recommend that you
contact your SUBARU dealer.
.Drive with caution and avoid
making sudden steering or driv-
ing maneuvers.
.Do not exceed a maximum speed
of 50 mph (80 km/h).
.Do not exceed a maximum driv-
ing distance of 125 miles (200
km).
.Do not use tire chains on a sealed
tire.
