ESP SUBARU FORESTER 2017 SJ / 4.G Repair Manual

Starting and operating/BSD/RCTA
BSD/RCTA (if equipped)
The BSD/RCTA consists of rear radar with
Blind Spot Detection and Rear Cross
Traffic Alert.
These functions enable the system to
detect objects or vehicles to the rear,
drawing attention to the driver when
changingalaneorwhendrivingin
reverse.
WARNING
The driver is responsible for driving
safely. Always be sure to check the
surroundings with your eyes when
changing lanes or reversing the
vehicle.
The system is designed to assist the
driver by monitoring the rear and
side areas of the vehicle during a
lane change or reversing. However,
you cannot rely on this system
alone in assuring the safety during
a lane change or reversing. Over-
confidence in this system could
result in an accident and lead to
serious injury or death. Since the
system operation has various limita-
tions, the flashing or illumination of
the BSD/RCTA approach indicatorlight may be delayed or it may not
operate at all even when a vehicle is
present in a neighboring lane or
approaching from either side.
The driver is responsible for paying
attention to the rear and side areas
of the vehicle.
&
System features
BSD/RCTA consists of the following func-
tions.
. To detect a vehicle in a blind spot on an
adjacent lane or a vehicle approaching at
high speed while driving the vehicle (Blind
Spot Detection)
. To detect a vehicle approaching from
the right or left while reversing the vehicle
(Rear Cross Traffic Alert)
The system uses radar sensors for the
above functions.
NOTE
The BSD/RCTA radar sensor has been
certified by the radio wave related laws
of the U.S. When driving in other
countries, certification of the country
where the vehicle is driven must be
obtained. For certification in the U.S.,
refer to “Certification for the BSD/
RCTA ”F 7-65. !
Blind Spot Detection (BSD)
1) Operating range
The system notifies the driver of vehicles
existing in the blind area. If the system
detects a vehicle existing in the blind area,
it warns the driver of dangers by illuminat-
ing the BSD/RCTA approach indicator
light(s) on the outside mirror(s). If the
driver operates the turn signal lever in the
direction where the BSD/RCTA approach
indicator light is illuminating, the system
warns the driver of dangers by flashing the
BSD/RCTA approach indicator light.

light may illuminate when driving close to
solid objects on the road or road side
(such as guardrails, tunnels and side-
walls).
. The BSD/RCTA approach indicator
light may flash when turning at an inter-
section in urban areas or a multilane
intersection.
. The BSD/RCTA approach indicator
light may flash and the warning buzzer

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

common sense precautions such as those
in the following list should be taken.
.Make certain that you and all of your
passengers are wearing seatbelts.
. Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio.
. Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain.
. Slow down and employ extra caution at
all times. When driving off-road, you will
not have the benefit of marked traffic
lanes, banked curves, traffic signs and
the like.
. Do not drive across steep slopes.
Instead, drive either straight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or
down slopes that are too steep.
. Avoid sharp turning maneuvers, espe-
cially at higher speeds.
. Do not grip the inside or spokes of the
steering wheel. A bad bump could jerk the
wheel and injure your hands. Instead drive
with your fingers and thumbs on the
outside of the rim.
. If driving through water, such as when
crossing shallow streams, first check the depth of the water and the bottom of the
stream bed for firmness and ensure that
the bed of the stream is flat. Drive slowly
and cross the stream without stopping.
The water should be shallow enough that
it does not reach the vehicle’
s under-
carriage. Water entering the engine air
intake or the exhaust pipe or water
splashing onto electrical parts may da-
mage your vehicle and may cause it to
stall. Never attempt to drive through
rushing water; regardless of its depth, it
can wash away the ground from under
your tires, resulting in possible loss of
traction and even vehicle rollover.
. Always check your brakes for effec-
tiveness immediately after driving in sand,
mud or water. Do this by driving slowly
and stepping on the brake pedal. Repeat
that process several times to dry out the
brake discs and brake pads.
. Do not drive or park over or near
flammable materials such as dry grass or
fallen leaves, as they may burn easily. The
exhaust system is very hot while the
engine is running and right after engine
stops. This could create a fire hazard.
. After driving through tall grass, mud,
rocks, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stones,
sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from the underbody. If the vehicle is used with
these materials trapped or adhering to the
underbody, a mechanical breakdown or
fire could occur.
.
Secure all cargo carried inside the
vehicle and make certain that it is not
piled higher than the seatbacks. During
sudden stops or jolts, unsecured cargo
could be thrown around in the vehicle and
cause injury. Do not pile heavy loads on
the roof. Those loads raise the vehicle’ s
center of gravity and make it more prone
to tip over.
. If you must rock the vehicle to free it
from sand or mud, depress the accelerator
pedal slightly and move the shift lever/
select lever back and forth between “1”/
“D ”and “R”repeatedly. Do not race the
engine. For the best possible traction,
avoid spinning the wheels when trying to
free the vehicle.
. When the road surface is extremely
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st. For CVT models with
manual mode, refer to “Selection of
manual mode ”F 7-27.
. Never equip your vehicle with tires
larger than those specified in this manual.
. Wash the vehicle’ s underbody after off-
road driving. Suspension components are
particularly prone to dirt buildup, so they

frost or snow etc. on the power rear
gate, remove it. If you forcibly
operate the power rear gate with
frost or snow, it may cause a mal-
function.
&Driving on snowy and icy
roads
To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle’ s braking perfor-
mance on snowy and icy roads. For
information on braking on slippery sur-
faces, refer to “ABS (Anti-lock Brake
System) ”F 7-37 and “Vehicle Dynamics
Control system ”F 7-39.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
vehicle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’sintakesystemandmay
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
! Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window.
If the wiper blades are frozen to the
windshield or rear window, perform the
following procedure.
. To thaw the windshield wiper blades,
use the defroster with the airflow selection
in “
”and the temperature set for
maximum warmth until the wiper blades
are completely thawed. Refer to “Climate
control ”F 4-1.
. If your vehicle is equipped with a wiper deicer, use it. It is helpful to thaw the
windshield wiper blades. Refer to
“Defog-
ger and deicer ”F 3-116.
. To thaw the rear wiper blade, use the
rear window defogger. Refer to “Defogger
and deicer ”F 3-116.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
with the airflow selection in “
”and the
temperature set for maximum warmth.
After the windshield gets warmed enough
to melt the frozen snow on it, wash it away
using the windshield washer. Refer to
“Windshield washer ”F 3-106.
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
warning flasher to alert other drivers.
Refer to “Hazard warning flasher ”F 3-8.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and freez-
ing temperatures. Blades of this type give
superior wiping performance in snowy
conditions. Be sure to use blades that
are suitable for your vehicle.

Driving tips/Loading your vehicle
NOTE
When tire chains cannot be used, use
of another type of traction device (such
as spring chains) may be acceptable if
use on your vehicle is recommended
by the device manufacturer, taking into
account tire size and road conditions.
Follow the device manufacturer’s in-
structions, especially regarding max-
imum vehicle speed.
To help avoid damage to your vehicle,
drive slowly, readjust or remove the
device if it is contacting your vehicle,
and do not spin your wheels. Damage
caused to your vehicle by use of a
traction device is not covered under
warranty.
Make certain that any traction device
you use is an SAE class S device, and
use it on the front wheels only. Always
use the utmost care when driving with
a traction device. Overconfidence be-
cause you are using a traction device
could easily lead to a serious accident.& Rocking the vehicle
If you must rock the vehicle to free it from
snow, sand, or mud, depress the accel-
erator pedal slightly and move the shift
lever/select lever back and forth between
“1”/“D ”and “R”repeatedly. Do not race the
engine. For the best possible traction,
avoid spinning the wheels when trying to
free the vehicle.
When the road surface is extremely
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than in 1st (MT models and CVT
models with manual mode).
If your vehicle is a CVT model with manual
mode, for information about holding the
transmission in the 2nd position, refer to
“Selection of manual mode ”F 7-27.
Loading your vehicle
WARNING
. Never allow passengers to ride
on a folded rear seatback or in
the cargo area. Doing so may
result in serious injury.
. Never stack luggage or other
cargo higher than the top of the
seatback because it could tumble
forward and injure passengers in
the event of a sudden stop or
accident. Keep luggage or cargo
low, as close to the floor as
possible.

Trailer towing
Your vehicle is designed and intended to
be used primarily as a passenger-carrying
vehicle. Towing a trailer puts additional
loads on your vehicle’s engine, drivetrain,
brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safety
and satisfaction depend upon proper use
of correct equipment and cautious opera-
tion of your vehicle. Seek the advice of
your SUBARU dealer to assist you in
purchasing a hitch and other necessary
towing equipment appropriate for your
vehicle. Do not use towing equipment
other than genuine SUBARU towing
equipment. In addition, be sure to follow
the instructions on correct installation and
use provided by SUBARU.
SUBARU assumes no responsibility for
injuries or vehicle damage that result from
trailer towing equipment, or from any
errors or omissions in the instructions
accompanying such equipment or for your
failure to follow the proper instructions.
Regularly check that the hitch mounting
bolts and nuts are tightened securely.
& Warranties and maintenance
SUBARU warranties do not apply to
vehicle damage or malfunction caused
by trailer towing. If you use your vehicle to
tow a trailer, more frequent maintenance
will be required due to the additional load.
(Refer to “Maintenance schedule under
severe driving conditions ”in the “Warranty
and Maintenance Booklet ”.)
Under no circumstances should a trailer
be towed with a new vehicle or a vehicle
with any new powertrain component (en-
gine, transmission, differential, wheel
bearings, etc.) for the first 1,000 miles
(1,600 km) of driving.
& Maximum load limits
WARNING
Never exceed the maximum load
limits explained in the following.
Exceeding the maximum load limits
could cause personal injury and/or
vehicle damage.
CAUTION
. Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg) total weight.
. Before towing a trailer, check the
trailer total weight, GVW, GAWs
and tongue load. Make sure the
load and its distribution in your
vehicle and trailer are accepta-
ble.
! Total trailer weight
Total trailer weight
The total trailer weight (trailer weight plus

the rear axle of the towing vehicle.
This may cause the rear wheels to
skid, especially during braking or
when vehicle speed is reduced dur-
ing cornering, resulting in over-
steer, spin out and/or jackknifing.
&Trailer hitches
WARNING
Never drill the frame or under-body
of your vehicle to install a commer-
cial trailer hitch. If you do, danger-
ous exhaust gas, water or mud may
enter the passenger compartment
through the drilled hole. Exhaust
gas contains carbon monoxide, a
colorless and odorless gas which is
dangerous, or even lethal, if inhaled.
Also, drilling the frame or under-
body of your vehicle could cause
deterioration of strength of your
vehicle and cause corrosion around
the drilled hole.
CAUTION
. Do not modify the vehicle ex-
haust system, brake system, or
other systems when installing a hitch or other trailer towing
equipment.
. Do not use axle-mounted hitches
as they can cause damage to the
axle housing, wheel bearings,
wheels or tires.
Do not use a trailer hitch other than a
genuine SUBARU trailer hitch. A genuine
SUBARU hitch is available from your
SUBARU dealer.
& Connecting a trailer
! Trailer brakes
WARNING
.Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg)
total weight.
. Do not directly connect your
trailer ’s hydraulic brake system
to the hydraulic brake system in
your vehicle. Direct connection
would cause the vehicle ’s brake
performance to deteriorate and
could lead to an accident.
If your trailer ’s total weight (trailer weight
plus its cargo weight) exceeds 1,000 lbs (453 kg), the trailer is required to be
equipped with its own brake system.
Electric brakes or surge brakes are
recommended, and must be installed
properly. Check that your trailer
’s brakes
conform with Federal, state/province and/
or other applicable regulations. Your
SUBARU ’s brake system is not designed
to be tapped into the trailer ’s hydraulic
brake system. Please ask your SUBARU
dealer and professional trailer supplier for
more information about the trailer ’s brake
system.
! Trailer safety chains
WARNING
Always use safety chains between
your vehicle and the trailer. Towing
trailer without safety chains could
create a traffic safety hazard if the
trailer separates from the hitch due
to coupling damage or hitch ball
damage.
In case the trailer hitch connector or hitch
ball should break or become discon-
nected, the trailer could get loose and
create a traffic safety hazard.
For safety, always connect the towing
vehicle and trailer with trailer safety
chains. Two chains should be used in

Appearance care/Corrosion protection
washing device.
.Clean the vehicle (including the alumi-
num wheels) with water as soon as
possible when it has been splashed with
sea water, exposed to sea breezes, or
driven on roads treated with salt or other
agents.Corrosion protection
Your SUBARU has been designed and
built to resist corrosion. Special materials
and protective finishes have been used on
most parts of the vehicle to help maintain
fine appearance, strength, and reliable
operation.
& Most common causes of
corrosion
The most common causes of corrosion
are:
1. The accumulation of moisture retain-
ing dirt and debris in body panel sections,
cavities, and other areas.
2. Damage to paint and other protective
coatings caused by gravel and stone
chips or minor accidents.
Corrosion is accelerated on the vehicle
when:
1. It is exposed to road salt or dust
control chemicals, or used in coastal
areas where there is more salt in the air,
or in areas where there is considerable
industrial pollution.
2. It is driven in areas of high humidity,
especially when temperatures range just
above freezing.
3. Dampness in certain parts of the vehicle remains for a long time, even
though other parts of the vehicle may be
dry.
4. High temperatures will cause corro-
sion to parts of the vehicle which cannot
dry quickly due to lack of proper ventila-
tion.
&
To help prevent corrosion
Wash the vehicle regularly to prevent
corrosion of the body and suspension
components. Also, wash the vehicle
promptly after driving on any of the
following surfaces.
. roads that have been salted to prevent
them from freezing in winter
. mud, sand, or gravel
. coastal roads
After the winter has ended, it is recom-
mended that the underbody be given a
very thorough washing.
Before the beginning of winter, check the
condition of underbody components, such
as the exhaust system, fuel and brake
lines, brake cables, suspension, steering
system, floor pan, and fenders. If any of
them are found to be rusted, they should
be given an appropriate rust prevention
treatment or should be replaced. Contact
your SUBARU dealer to perform this kind

Maintenance and service/Replacement of brake pad and lining
Replacement of brake pad
and lining
The disc brakes 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.
CAUTION
If you continue to drive despite the
scraping noise from the audiblebrake pad wear indicator, it will
result in the need for costly brake
rotor repair or replacement.
&
Breaking-in of new brake
pads and linings
When replacing the brake pad or lining,
use only genuine SUBARU parts. After
replacement, the new parts must be
broken in as follows.
! Brake pad and lining
While maintaining a speed of 30 to 40
mph (50 to 65 km/h), step on the brake
pedal lightly. Repeat this five or more
times.
! Parking brake lining
1. Drive the vehicle at a speed of
approximately 22 mph (35 km/h).
2. With the parking brake release button
pushed in, pull the parking brake lever
SLOWLY and GENTLY (pulling with a
force of approximately 33.7 lbf [150 N,
15.3 kgf]).
3. Drive the vehicle for approximately
220 yards (200 meters) in this condition.
4. Wait 5 to 10 minutes for the parking
brake to cool down. Repeat this proce-
dure.
5. Check the parking brake stroke. If the parking brake stroke is out of the specified
range, adjust it by turning the adjusting nut
located on the parking brake lever.
Parking brake stroke:
7–8 notches / 45 lbf (200 N, 20.4 kgf)
WARNING
A safe location and situation should
be selected for break-in driving.
CAUTION
Pulling the parking brake lever too
forcefully may cause the rear
wheels to lock. To avoid this, be
certain to pull the lever up slowly
and gently.
