ESP SUBARU IMPREZA 2016 5.G Repair Manual

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.

the following table shows the required tire
pressures that correspond to various out-

in the garage is 608F (15.6 8C).
Example:
Tire size: P205/55R16 89V and
P205/50R17 88V
Standard tire pressures:
Front: 33 psi (230 kPa, 2.3 kgf/cm

If the low tire pressure warning light
illuminates when you drive the vehicle in
cold outside air after adjusting the tire
pressures in a warm garage, re-adjust the
tire pressures using the method described
above. Then, increase the vehicle speed
to at least 20 mph (32 km/h) and check to
see that the low tire pressure warning light
turns off a few minutes later. If the low tire
pressure warning light does not turn off, the tire pressure monitoring system may
not be functioning normally. In this event,
go to a SUBARU dealer to have the
system inspected as soon as possible.
While the vehicle is driven, friction be-
tween tires and the road surface causes
the tires to warm up. After illumination of
the low tire pressure warning light, any
increase in the tire pressures caused by
an increase in the outside air temperature
or by an increase in the temperature in the
tires can cause the low tire pressure
warning light to turn off.
System resetting is necessary when the
wheels are changed (for example, a
switch to snow tires) and new TPMS
valves are installed on the newly fitted
wheels. Have this work performed by a
SUBARU dealer following wheel replace-
ment.
It may not be possible to install TPMS
valves on certain wheels that are on the
market. Therefore, if you change the
wheels (for example, a switch to snow
tires), use wheels that have the same part
number as the standard-equipment
wheels. Without four operational TPMS
valve/sensors on the wheels, the TPMS
will not fully function and the warning light
on the combination meter will illuminate
steadily after blinking for approximatelyone minute.
When a tire is replaced, adjustments are
necessary to ensure continued normal
operation of the tire pressure monitoring
system. As with wheel replacement, there-
fore, you should have the work performed
by a SUBARU dealer.
WARNING
If the low tire pressure warning light
does not illuminate briefly after the
ignition switch is turned ON or the
light illuminates steadily after blink-
ing for approximately one minute,
you should have your Tire Pressure
Monitoring System checked at a
SUBARU dealer as soon as possi-
ble.
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

Maintenance and service/Tires and wheels
NOTE
.The air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3
kgf/cm
2) when the tire becomes warm.
. The tires are considered cold when
the vehicle has been parked for at least
three hours or has been driven less
than one mile (1.6 km).
WARNING
Do not let air out of warm tires to
adjust pressure. Doing so will result
in low tire pressure.
Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally. .
Correct tire pressure (tread worn
evenly)
Roadholding is good, and steering is
responsive. Rolling resistance is low, so
fuel consumption is also lower. .
Abnormally low tire pressure (tread
worn at shoulders)Rolling resistance is high, so fuel con-
sumption is also higher.

Fuses
CAUTION
Never replace a fuse with one hav-
ing a higher rating or with material
other than a fuse because serious
damage or a fire could result.
The fuses are designed to melt during an
overload to prevent damage to the wiring
harness and electrical equipment. The
fuses are located in two fuse boxes.
One is located under the instrument panel
behind the fuse box cover on the driver ’s
seat side. To remove the cover, pull it out.
1) Spare fuses
The other one (main fuse box) is housed
in the engine compartment. Also, the
spare fuses are stored in the fuse box
cover.
The fuse puller is stored in the main fuse box in the engine compartment.
1) Good
2) Blown
If any lights, accessories or other electrical
controls do not operate, inspect the
corresponding fuse. If a fuse has blown,
replace it.
1. Turn the ignition switch to the
“LOCK”/
“OFF ”position and turn off all electrical
accessories.
2. Remove the cover.
3. Determine which fuse may be blown.
Look at the back side of each fuse box
cover and refer to “Fuses and circuits”
F 12-10.

Consumer information and Reporting safety defects/Reporting safety defects (U.S.A.)
grade C corresponds to a level of
performance which all passenger
car tires must meet under the
Federal Motor Vehicle Safety Stan-
dards No. 109. Grades B and A
represent higher levels of perfor-
mance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this
tire is established for a tire
that is properly inflated and
not overloaded. Excessive
speed, underinflation, or ex-
cessive loading, either sepa-
rately or in combination, can
cause heat buildup and possi-
ble tire failure.
Reporting safety defects
(U.S.A.)
If you believe that your vehicle has
a defect which could cause a
crash or could cause injury or
death, you should immediately in-
form the National Highway Traffic
Safety Administration (NHTSA) in
addition to notifying Subaru of
America, Inc.
If NHTSA receives similar com-
plaints, it may open an investiga-
tion, and if it finds that a safety
defect exists in a group of vehi-
cles, it may order a recall and
remedy campaign. However,
NHTSA cannot become involved
in individual problems between
you, your dealer, or Subaru of
America, Inc. To contact NHTSA,
you may call the Vehicle Safety
Hotline toll-free at 1-888-327-4236
(TTY: 1-800-424-9153); go to
http://www.safercar.gov; or write
