2017 SUBARU FORESTER speed sensor

Starting and operating/BSD/RCTA
1) The detection range of the radar sensors
2) The out of detection range of the radarsensors
B) Vehicle that may not be detected
WARNING
The approaching vehicle (B) may
not be detected because the vehicle
reversing is blocked by a parked
vehicle. Always be sure to check the
surroundings with your eyes when
reversing the vehicle, because the
detectability of RCTA is limited.
& System operation
! Operating conditions
The BSD/RCTA will operate when all of
the following conditions are met.
. The ignition switch is in the “ON ”
position.
. The BSD/RCTA warning indicator and
BSD/RCTA OFF indicator are turned off.
. The vehicle is driven at speeds above
6 mph (10 km/h) (except when reversing).
. The shift lever/select lever is in the “R”
position (RCTA only).
The BSD/RCTA will not operate in the
following situations.
. The BSD/RCTA OFF indicator is on.
. The vehicle speed is below 6 mph (10
km/h) even when the BSD/RCTA OFF
indicator remains off (except when rever-
sing).
NOTE
. In the following case, the BSD/RCTA
will stop operating and the BSD/RCTA
warning indicator will appear. If the
BSD/RCTA warning indicator appears,
have your vehicle inspected at a
SUBARU dealer as soon as possible.
–When a malfunction occurs in the
system, including the BSD/RCTA
approach indicator light .
In the following cases, the BSD/
RCTA will temporarily stop operating
(or may stop operating) and the BSD/
RCTA warning indicator will appear.
–When the radar sensor becomes
significantly misaligned (If the or-
ientation of the radar sensor is
shifted for any reason, readjust-
ment is required. Have the sensor
adjusted at a SUBARU dealer.)
– When a large amount of snow or
ice sticks to the rear bumper sur-
face around the radar sensors
– When the vehicle is driven on a
snow-covered road or in an envir-
onment in which there are no
objects around (such as in a desert)
for a long time
– When the temperature around
the radar sensors increased exces-
sively due to long driving on uphill
grades in summer, etc.
– When the temperature around
the radar sensors becomes extre-
mely low
– When the vehicle battery voltage
lowers
– When the vehicle battery be-
comes overvoltage
When the above conditions are cor-
rected, the BSD/RCTA will resume
7-60

operation and the BSD/RCTA warning
indicator will disappear. However, if the
BSD/RCTA warning indicator has ap-
peared for a prolonged time, have the
system inspected at a SUBARU dealer
as soon as possible.
.The detectability of the radar sen-
sors is restricted. The BSD/RCTA de-
tection may be impaired and the sys-
tem may not operate properly under the
following conditions.
–When the rear bumper around
the radar sensors is distorted
– When ice, snow or mud adheres
to the rear bumper surface around
the radar sensors
– When stickers, etc. are affixed on
the areas of the radar sensors on
the rear bumper
– During adverse weather condi-
tions such as rain, snow or fog
– When driving on wet roads such
as snow-covered roads and
through puddles
. The radar sensors may not detect or
may have difficulty detecting the fol-
lowing.
–Small motorcycles, bicycles, pe-
destrians, stationary objects on the
road or road side, etc.
– Vehicles with body shapes that
the radar may not reflect (vehicles with a low body height such as
sports cars or a trailer with no
cargo)
–
Vehicles that are not approach-
ing your vehicle even though they
are in the detection area (either on a
neighboring lane to the rear or
beside your vehicle when rever-
sing) (The system determines the
presence of approaching vehicles
based on data detected by the radar
sensors.)
– Vehicles traveling at significantly
different speeds
– Vehicles driving in parallel at
almost the same speed as your
vehicle for a prolonged time
– Oncoming vehicles
– Vehicles in a lane beyond the
neighboring lane
– Vehicles travelling at a signifi-
cantly lower speed that you are
trying to overtake
. On a road with extremely narrow
lanes, the system may detect vehicles
driving in a lane next to the neighbor-
ing lane.& BSD/RCTA approach indica-

Starting and operating/Reverse Automatic Braking System
NOTE
.To ensure correct operation of the
BSD/RCTA, observe the following pre-
cautions.
–Always keep the bumper surface
near the radar sensors clean.
– Do not affix any stickers or other
items on the bumper surface near
the radar sensors.
– Do not modify the bumper near
the radar sensors.
– Do not paint the bumper near the
radar sensors.
– Do not expose the bumper near
the radar sensors to strong im-
pacts. If a sensor becomes misa-
ligned, a system malfunction may
occur, including the inability to
detect vehicles entering the detec-
tion 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.
. If 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
driving 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
allevenwhenanobstacleis
present in the reversing direc-
tion.
. The system is not designed to detect 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 become
unstable.
NOTE
The 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 con-
tracted by SUBARU may acquire
and use the recorded data for the
purpose of vehicle research and
development. SUBARU and third
parties contracted by SUBARU will
not disclose or provide the acquired
7-66

data to any other third party except
under the following conditions.– The vehicle owner has given his/
her consent.
– The disclosure/provision is
based on a court order or other
legally enforceable request.
– Data that has been modified so
that the user and vehicle cannot be
identified is provided to a research
institution for statistical processing
or similar purposes.
& Reverse Automatic Braking
System overview
The 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 activate. If the
vehicle is further reversed, automatic 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 brakes may acti-
vate. In this case, remain calm and
either continue to depress the accel-
erator pedal or cancel the system. To cancel the system, refer to
“Can-
celing the Reverse Automatic Brak-
ing system operation ”F 7-72.
& Operating conditions
The Reverse Automatic Braking system
will operate when all of the following
conditions are met.
. The ignition switch is in the “ON ”
position
. The EyeSight warning indicator is off
. The Reverse Automatic Braking fail
indicator is off
. HALT (Reverse Automatic Braking
system OFF) indicator is off
. The Reverse Automatic Braking sys-
tem is set to on
. The select lever is in the “R ”position
. The vehicle speed is between 1 to 9
mph (1.5 to 15 km/h)
NOTE
. When the Reverse Automatic Brak-
ing fail indicator is illuminated, the

nated, the Reverse Automatic Braking
system cannot be operated.
.In the following cases, the system
may not be able to properly detect an
obstacle. Promptly contact a SUBARU
dealer to have the system inspected.
–A sticker, paint, or a chemical is
applied to the rear bumper near the
sonar sensor
– The rear bumper is modified
– The rear bumper has been re-
moved and reattached
– The ground clearance is changed
due to the vehicle ’s loading condi-
tion or modification
– Ice, snow or mud is adhered to
the rear bumper near the sonar
sensor
– The rear bumper is exposed to
strong impact, or the rear bumper is
deformed
. On a steep hill, the system ’s auto-
matic braking ability will be reduced.
. The system is designed to avoid
collisions by automatic hard braking
when the vehicle ’s reversing speed is
less than approximately 3 mph (5
km/h). However, the system does not
guarantee that the vehicle will be able
to avoid collisions in any situation.
. If the vehicle is reversed at an
extremely slow speed, the driver ’s operation may be prioritized. In this
case, automatic braking will not oper-
ate.
.
The system may not be able to
detect the following objects
–Sharp or thin objects such as
poles, fences and ropes which may
not reflect the sound wave emitted
from the sonar sensor
– Objects that are too close to the
rear bumper when the select lever is
set to the “R ” position
– Objects with a surface which may
not reflect the sound wave emitted
from the sonar sensor such as a
chain link fence.
. Objects the system is not designed
to detect
–Pedestrians
– Moving objects including moving
vehicles
– Objects which absorb sound
waves such as cloth or snow
– Objects whose surface has a
diagonal angle
– Objects that are low to the
ground such as parking blocks
– Objects that are high above the
ground such as objects hanging
from above
. The system may not be able to
properly detect objects or may cause a system malfunction when the follow-
ing conditions exist
High frequency sound from other
sources are nearby– Horn sound from another vehicle
– Engine sound from other vehi-
cles
– Sound of an air brake
– Vehicle detection equipment or a
sonar from another vehicle
– A sound wave with a frequency
similar to the vehicle ’s system is
transmitted nearby
– A
vehicle equipped with the same
system is reversing toward your
reversing direction
Weather conditions – Extremely high or extremely low
temperatures in which the area near
the sonar sensor becomes too hot
or too cold to operate
– The rear bumper near the sonar
sensors is exposed to heavy rain or
a significant amount of water
– Fog, snow or sandstorm, etc.
– Air is moving rapidly such as
when a strong wind is blowing

In case of emergency/Flat tires
17. When storing the spare tire after
repairing a flat tire, be sure to place the
spacer in the manner shown in the
illustration, and then tighten the bolt in
the rear side of the bracket.
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)
Low tire pressure warning light (type A)
Low tire pressure warning light (type B)
The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when a tire
pressure is severely low relative to the
selected TPMS mode.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 25 mph (40 km/h). Also,
this system may not react immediately to a
sudden drop in tire pressure (for example,
a blow-out caused by running over a
sharp object).
WARNING
If the low tire pressure warning light
illuminates while driving, never
brake suddenly and keep driving
straight ahead while gradually redu-
cing speed. Then slowly pull off the
road to a safe place. Otherwise an
accident involving serious vehicle
damage and serious personal injury
could occur.
Check the pressure for all four tires
and adjust the pressure to the COLD
tire pressure shown on the vehicle
placard on the door pillar on the
driver ’s side. If this light still illumi-
nates while driving after adjusting
the tire pressure, a tire may have

the underbody. Carefully flush the suspen-
sion and axle parts, as they are particu-
larly 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 polishing
Always 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
surface 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 recom-
mended. 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
acompoundoranincorrectpolishing
technique will result in removing the paint layer and exposing the undercoat. When
in doubt, it is always best to contact your
SUBARU dealer or an auto paint specia-
list.
CAUTION
Do not use any agents with organic
solvents on the surface of the bulb
assembly cover. However, if a polish
or wax with organic solvents is
applied to the cover surface, com-
pletely wipe off the polish or wax.
Otherwise, the cover surface may be
damaged.
NOTE
Be careful not to block the windshield
washer nozzles with wax when waxing
the vehicle.
&
Cleaning aluminum wheels
. Promptly wipe the aluminum wheels
clean of any kind of grime or agent. If dirt
is left on too long, it may be difficult to
clean off.
. Do not use soap containing grit to
clean the wheels. Be sure to use a neutral
cleaning agent, and later rinse thoroughly
with water. Do not clean the wheels with a
stiff brush or expose them to a high-speed

Parking brake stroke
Check the parking brake stroke according
to the maintenance schedule in the
“Warranty and Maintenance Booklet ”.
When the parking brake is properly
adjusted, braking power is fully applied
by pulling the lever up 7 to 8 notches
gently but firmly (approximately 45 lbf [200
N, 20.4 kgf]). If the parking brake lever
stroke is not within the specified range,
have the brake system checked and
adjusted at your SUBARU dealer.
Tires and wheels
& Types of tires
You should be familiar with type of tires
present on your vehicle.
! All season tires
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads.
All season tires are identified by “ALL
SEASON ”and/or “M+S ”(Mud & Snow) on
the tire sidewall.
! Summer tires
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-
covered or icy roads.
If you drive your vehicle on snow-covered
or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to
replace all four tires. !
Winter (snow) tires
Winter tires are best suited for driving on
snow-covered and icy roads. However
winter tires do not perform as well as
summer tires and all season tires on roads
other than snow-covered and icy roads.
& Tire pressure monitoring
system (TPMS) (if equipped)
The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low. The tire pressure monitor-
ing system will activate only when the
vehicle is driven. Also, this system may
not react immediately to a sudden drop in
tire pressure (for example, a blow-out
caused by running over a sharp object).
If you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to
pressures higher than those shown on the
tire placard. Specifically, inflate them by an
extra 1 psi (6.9 kPa, 0.07 kgf/cm
2) for
every difference of 10 8F (5.6 8C) between
the temperature in the garage and the
