inflated to the inflation pressure recom-
mended by the vehicle manufacturer on
the vehicle placard or tire inflation pres-
sure label. (If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure
label, you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicatewhen the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the installation of replacement or
alternate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
Should the warning light illuminate steadily
after blinking for approximately one min-
ute, have the system inspected by your
nearest SUBARU dealer as soon as
possible.
WARNING
If this light does not illuminate
briefly after the ignition switch is
turned ON or the light illuminates
steadily after blinking for approxi-
mately one minute, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.
If this light illuminates while driving,
never brake suddenly and keep
driving straight ahead while gradu-
ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving
serious vehicle damage and serious
personal injury could occur.
If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, replace it with a spare tire
as soon as possible.
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 TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting.
If the light illuminates steadily after
blinking for approximately one min-
ute, promptly contact a SUBARU
dealer to have the system inspected.
CAUTION
The tire pressure monitoring system
is NOT a substitute for manually
checking tire pressure. The tire
pressure should be checked peri-
odically (at least monthly) using a
tire gauge. After any change to tire
pressure(s), the tire pressure mon-
itoring system will not re-check tire
inflation pressures until the vehicle
is first driven more than 20 mph (32
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 20 mph (32 km/h) to start the
TPMS re-checking of the tire infla-
tion pressures. If the tire pressures
are now above the severe low pres-
sure threshold, the low tire pressure
warning light should turn off a few
minutes later. Therefore, be sure to
install the specified size for the frontand rear tires.
&ABS warning light
CAUTION
.If any of the following conditions
occur, we recommend that you
have the ABS repaired at the first
available opportunity by your
SUBARU dealer.
–The warning light does not
illuminate when the ignition
switch is turned to the“ON”
position.
–The warning light illuminates
when the ignition switch is
turned to the“ON”position,
but it does not turn off even
after the vehicle is started.
–The warning light illuminates
during driving.
.When the warning light is on (and
the brake system warning light is
off), the ABS function shuts
down. However, the conventional
brake system continues to oper-
ate normally.
The ABS warning light, Vehicle Dynamics
Control warning light, and brake systemwarning light illuminate simultaneously if
the EBD system malfunctions. For further
details of the EBD system malfunction
warning, refer to“Electronic Brake Force
Distribution (EBD) system warning”F3-
21.
NOTEIf the warning light behavior is as
described in the following conditions,
the ABS may be considered normal.
.The warning light illuminates when
the ignition switch is turned to the“ON”
position and turns off approximately 2
seconds after the engine has started.
.The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.
.The warning light remains illumi-
nated after the engine has been started,
but it turns off while driving.
.The warning light illuminates during
driving, but it turns off immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may illumi-
nate. This is due to the low battery voltage
and does not indicate a malfunction. When
the battery becomes fully charged, the
light will turn off.

&Brake system
warning light (red)This light illuminates with the parking
brake applied while the ignition switch is
in the“ON”position. It turns off when the
parking brake is fully released.
WARNING
.Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains illuminated,
have the brakes inspected by a
SUBARU dealer immediately.
.If at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.
The brake system warning light has the
following functions.
!Brake fluid level warningThis light illuminates when the brake fluid
level has dropped to near the“MIN”level of
the brake fluid reservoir with the ignition
switch in the“ON”position and with the
parking brake fully released.If the brake system warning light should
illuminate while driving (with the parking
brake fully released and with the ignition
switch positioned in“ON”), it could be an
indication of leaking of brake fluid or worn
brake pads. If this occurs, immediately
stop the vehicle at the nearest safe
location and check the brake fluid level. If
the fluid level is below the“MIN”mark in
the reservoir, do not drive the vehicle.
Have the vehicle towed to the nearest
SUBARU dealer for repair.
!Electronic Brake Force Distribution
(EBD) system warning
The EBD system may be malfunctioning if
the brake system warning light
/
,
Vehicle Dynamics Control warning light
and ABS warning light
/
illuminate
simultaneously during driving.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are
applied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.
If the brake system warning light
/
,
Vehicle Dynamics Control warning light
and ABS warning light
/
illuminate
simultaneously, take the following steps.
1. Stop the vehicle in the nearest safe, flatlocation.
2. Shut down the engine, apply the
parking brake and then restart it.
3. Fully release the parking brake.
4. Even if all the warning lights do not
come back on, the EBD system may have
a possible malfunction. Drive carefully to
the nearest SUBARU dealer and have the
system inspected.
5. If all the warning lights stay illuminated
or come back on after approximately 2
seconds, shut down the engine, apply the
parking brake and check the brake fluid
level.
.If the brake fluid level is not below the
“MIN”mark, the EBD system may be
malfunctioning. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
.If the brake fluid level is below the“MIN”
mark, DO NOT drive the vehicle. Instead,
have the vehicle towed to the nearest
SUBARU dealer for repair.
!Vacuum pressure system warning
The brake system warning light
/
will
illuminate when the vacuum pressure
sensor is malfunctioning or brake booster
pressure is decreasing.
If the brake warning light continues to
illuminate for several minutes after starting

never brake suddenly. Instead,
perform the following procedure.
Otherwise, an accident involving
serious vehicle damage and ser-
ious personal injury could occur.
(1) Keep driving straight ahead
while gradually reducing
speed.
(2) Slowly pull off the road to a
safe location.
(3) Check the pressure for all four
tires and adjust the pressure
to the COLD tire pressure
shown on the tire placard.
The tire placard is located on
the door pillar on the driver’s
side.
Even when the vehicle is driven a
very short distance, the tires get
warm and their pressures in-
crease accordingly. Be sure to
let the tires cool thoroughly be-
fore adjusting their pressures to
the standard values shown on the
tire placard. Refer to“Tires and
wheels”F11-21. The tire pres-
sure monitoring system does not
function when the vehicle is sta-
tionary. After adjusting the tire
pressures, increase the vehicle
speed to at least 20 mph (32 km/h)to start the TPMS rechecking of
the tire inflation pressures. If the
tire pressures are now above the
severe low pressure threshold,
the low tire pressure warning
light should turn off a few min-
utes later.
If this light still illuminates while
driving after adjusting the tire
pressure, a tire may have signifi-
cant damage and a fast leak that
causes the tire to lose air rapidly.
If you have a flat tire, replace it
with a spare tire as soon as
possible.
.When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/trans-
mitter being transferred, the low
tire pressure warning light will
illuminate steadily after blinking
for approximately one minute.
This indicates the 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.
.When a tire is repaired with liquid
sealant, the tire pressure warning
valve and transmitter may not
operate properly. If a liquid sea-lant is used, contact your nearest
SUBARU dealer or other qualified
service shop as soon as possi-
ble. Make sure to replace the tire
pressure warning valve and
transmitter when replacing the
tire. You may reuse the wheel if
there is no damage to it and if the
sealant residue is properly
cleaned off. Do not inject any tire
liquid or aerosol tire sealant into
the tires, as this may cause a
malfunction of the tire pressure
sensors. If the light illuminates
steadily after blinking for ap-
proximately one minute,
promptly contact a SUBARU
dealer to have the system in-
spected.
CAUTION
Do not place metal film or any metal
parts in the cargo area. This may
cause poor reception of the signals
from the tire pressure sensors, and
the tire pressure monitoring system
will not function properly.

sensor becomes misaligned, a system
malfunction may occur, including the in-
ability to detect vehicles entering the
detection areas. If any strong shock is
applied to the bumper, be sure to contact
your SUBARU dealer for inspection.
.Do not disassemble the radar sensors.NOTEIf the radar sensors require repair or
replacement, or the bumper area
around the radar sensors requires
repair, paintwork or replacement, con-
tact your SUBARU dealer for assis-
tance.
Reverse Automatic Braking
System (if equipped)Reverse Automatic Braking is a system
designed to help avoid collisions or reduce
collision damage when reversing the
vehicle. If a wall or an obstacle is detected
in the reversing direction, the system will
notify the driver with a warning sound and
may activate the vehicle’s brakes auto-
matically.
WARNING
.Reverse Automatic Braking is not
a system intended to replace the
driver’s responsibility to check
surrounding areas for vehicles or
obstacles to avoid a collision.
.The driver is responsible for driv-
ing safely. Always be sure to
check the surroundings visually
when reversing the vehicle.
.Since the system operation has
various limitations, the warning
sound or automatic braking may
be delayed or may not operate at
all even when an obstacle is
present in the reversing direc-
tion.
.The system is not designed todetect people (including chil-
dren), animals or other moving
objects.
.Depending on the vehicle condi-
tion or the surrounding environ-
ment, the sonar sensor’s ability
to detect objects may be compro-
mised.
NOTEThe Reverse Automatic Braking Sys-
tem records and stores the following
data when automatic braking operates.
It does not record conversations, per-
sonal information or other audio data.
.Distance from the object
.Vehicle speed
.Accelerator pedal operation status
.Brake pedal operation status
.Select lever position
.Outside temperature
.The sensitivity setting of the sonar
sensors
SUBARU and third parties contracted
by SUBARU may acquire and use the
recorded data for the purpose of vehi-
cle research and development.
SUBARU and third parties contracted
by SUBARU will not disclose or provide
the acquired data to any other third

System overviewThe system detects objects using sonar
sensors installed in the rear bumper.
.If the system determines a possible
collision with an object in the reversing
direction, automatic deceleration will be
activated. Also, beeping sounds will acti-
vate.
.If the vehicle is further reversed, auto-
matic hard braking will be applied and a
continuous beeping sound will activate.!Detecting range
1) Detecting range (width): Approximately 6
in (15 cm) outside of the vehicle width
2) Range that the system cannot detect:
Approximately 20 in (50 cm) behind the
rear of the vehicle
3) Detecting range (length): Approximately
5 ft (1.5 m) from the rear of the vehicle
WARNING
If your vehicle is trapped on a rail-
road crossing and you are trying to
escape by reversing through the
crossing gate, the system may re-
cognize the crossing gate as an
obstacle and the brake may activate.
In this case, remain calm and either
continue to depress the accelerator
pedal or cancel the system. Tocancel the system, refer to“Cancel-
ing the Reverse Automatic Braking

WARNING
Never place a tire or tire changing
tools in the passenger compartment
after changing wheels. In a sudden
stop or collision, loose equipment
could strike occupants and cause
injury. Store the tire and all tools in
the proper place.&Tire pressure monitoring
system (TPMS) (U.S.-spec.
models)The tire pressure monitoring system pro-
vides the driver with the warning message
indicated by sending a signal from a
sensor that is installed in each wheel when
tire pressure is severely low.The tire pressure monitoring system will
activate only when the vehicle is driven.
Also, this system may not react immedi-
ately to a sudden drop in tire pressure (for
example, a blow-out caused running over
a sharp object).
WARNING
.If the low tire pressure warning
light illuminates while driving,
never brake suddenly. Instead,
perform the following procedure.
(1) Keep driving straight ahead
while gradually reducing
speed.
(2) Slowly pull off the road to a
safe place. Otherwise an acci-
dent involving serious vehicle
damage and serious personal
injury could occur.

!Washing the underbody
Chemicals, salts and gravel used for
deicing road surfaces are extremely cor-
rosive, accelerating the corrosion of un-
derbody components, such as the exhaust
system, fuel and brake lines, brake cables,
floor pan and fenders, and suspension.
Thoroughly flush the underbody and inside
of the fenders with lukewarm or cold water
at frequent intervals to reduce the harmful
effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-
sion.
After driving off-road or on muddy or sandy
roads, wash the mud and sand off the
underbody. Carefully flush the suspension
and axle parts, as they are particularly
prone to mud and sand buildup. Do not use
a sharp-edged tool to remove caked mud.
CAUTION
.Be careful not to damage brake
hoses, sensor harnesses, and
other parts when washing sus-
pension components.
.Be careful not to flush the engine
bottom for a long time. It may
cause damage of some electrical
parts.
!Using a warm water washer
.Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle.
.Do not wash the same area continu-
ously.
.If a stain will not come out easily, wash
by hand. Some warm water washers are of
the high temperature, high pressure type,
and they can damage or deform the resin
parts such as moldings, or cause water to
leak into the vehicle.
&Waxing and polishingAlways wash and dry the vehicle before
waxing and polishing.
Use a good quality polish and wax and
apply them according to the manufac-
turer’s instructions. Wax or polish when
the painted surface is cool.
Be sure to polish and wax the chrome trim,
as well as the painted surfaces. Loss of
wax on a painted surface leads to loss of
the original luster and also quickens the
deterioration of the surface. It is recom-
mended that a coat of wax be applied at
least once a month, or whenever the
surface no longer repels water.
If the appearance of the paint has dimin-
ished to the point where the luster or tone
cannot be restored, lightly polish the sur-
face with a fine-grained compound. Never
polish just the affected area, but include
the surrounding area as well. Always
polish in only one direction. A No. 2000
grain compound is recommended. Never
use a coarse-grained compound. Coarse-
grained compounds have a smaller grain-
size number and could damage the paint.
After polishing with a compound, coat with
wax to restore the original luster. Frequent
polishing with a compound or an incorrect
polishing technique will result in removing
the paint layer and exposing the under-
