change wheel SUBARU WRX 2016 User Guide

The auto mode has 3 modes as follows. Mode Operation
AUTO [+] This mode emphasizes traction
control and strengthens the
limitation of differential action
that is suitable for driving on
slippery roads for vehicle stabi-
lity.
AUTO This mode is suitable for most
driving situations.
AUTO [ − ] This mode is suitable when you
seek quick response from the
steering wheel and smooth
driving.
! Mode setting method
In most situations, it is recommended that
the “ AUTO ” mode is selected.
Push the control switch forward to select the “ AUTO [+] ” mode. After setting the
mode, “ AUTO [+] ” appears.
Pull the control switch rearward to select
the “ AUTO [ − ] ” mode. After setting the
mode, “ AUTO [ − ] ” appears.
When the “ AUTO [+] ” mode is selected,
pull the control switch rearward to change
to the “ AUTO ” mode. When the “ AUTO
[ − ] ” mode is set, push the control switch
forward to change to the “ AUTO ” mode.& Manual mode
In the manual mode, you can use the
center differential control switch to adjust
the initial LSD torque as desired. When
this mode is selected, the “ AUTO ” indica-
tor disappears.Starting and operating/Driver ’ s Control Center Differential (C.DIFF/DCCD) (STI)

Starting and operating/Driver ’ s Control Center Differential (C.DIFF/DCCD) (STI)
! Center differential control switch
and indicator
The control switch is located beside the
parking brake lever. By pushing the
control switch forward or pulling it rear-
ward, it is possible to change the initial
LSD torque.
The center differential indicator on the
combination meter gives six levels of
indication. The indicator and control
switch are linked; when the switch is
pushed or pulled to change the initial
LSD torque, the indicator changes accord-
ingly. Push the switch forward to increase the
initial LSD torque; when the “ LOCK ”
indicator appears, the initial LSD torque
setting is maximum. The center differential
will then be almost completely locked. Pull the switch rearward to reduce the
initial LSD torque. When the lowest posi-
tion of the driver ’ s control center differen-
tial indicator is displayed, the initial LSD
torque will be minimum. Under this condi-
tion, only the Mechanical LSD torque will
limit the differential action.
CAUTION
. Do not operate the control switch
when a wheel slippage occurs.
Wait until the wheelspin has been
brought under control.
. Under any of the following con-
ditions after setting to the man-
ual mode, pull the center differ-
ential control switch to minimize
the initial LSD torque:7-22

“ ” appears, downshifting is possible.
When both indicators appear, upshifting
and downshifting are both possible. When
the vehicle stops (for example, at traffic
signals), the downshift indicator turns off.
Gearshifts can be performed using the
shift paddle behind the steering wheel.
To upshift to the next higher gear position,
pull the shift paddle that has “ + ” indicated
on it. To downshift to the next lower gear
position, pull the shift paddle that has “ – ”
indicated on it.
To deselect the manual mode, return the
select lever to the “ D ” position from the “ M ”
position. CAUTIONDo not place or hang anything on
the shift paddles. Doing so may
result in accidental gear shifting.
NOTE Please read the following points care-
fully and bear them in mind when using
the manual mode.
. If you attempt to shift down when
the engine speed is too high, i.e., when
a downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible.
. If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond.
. You can perform a skip-shift (for
example, from 4th to 2nd) by operating
the shift paddle twice in rapid succes-
sion.
. The transmission automatically se-
lects 1st gear when the vehicle stops
moving.
. If the temperature of the transmis-
sion fluid becomes too high, the “ AT
OIL TEMP ” warning light on the combi-
nation meter will illuminate. Immedi-
ately stop the vehicle in a safe location and let the engine idle until the warning
light turns off.
. By selecting the Sport Sharp (S#)
mode, upshifting will not occur auto-
matically. According to the road condi-
tions, shift change manually so that the
tachometer needle does not enter the
red zone. Also, if the engine revolu-
tions reach the specified number, the
fuel supply will be cut. In this case,
perform shift up operation.
& Shift lock function The shift lock function helps prevent the
improper operation of the select lever.
. The select lever cannot be operated
unless the ignition switch is turned to the
“ ON ” position and the brake pedal is
depressed.
. The select lever cannot be moved from
the “ P ” position to any other position
before the brake pedal is depressed.
Depress the brake pedal first, and then
operate the select lever.
. Only the “ P ” position allows you to turn
the ignition switch from the “ ACC ” position
to the “ LOCK ” / “ OFF ” position and remove
the key from the ignition switch.
. If the ignition switch is turned to the
“ LOCK ” / “ OFF ” position while the select
lever is in the “ N ” position, the select leverStarting and operating/Continuously variable transmission

other than Sport Sharp (S#) mode is
selected.
NOTE . The next time you turn on the
engine, after you turned off the engine
in the Sport Sharp (S#) mode, the SI-
DRIVE mode changes to the Sport (S)
mode.
. The next time you turn on the
engine, after you turned off the engine
in the Sport (S) mode or Intelligent (I)
mode, the SI-DRIVE mode will stay in
the same mode as when the engine
was turned off.
. While the engine is running, if the
CHECK ENGINE warning light/malfunc-
tion indicator light illuminates, the SI-
DRIVE mode changes to the Sport (S)
mode. In this case, it is not possible to
change to another mode.
. If there is a possibility that the
engine could overheat because of a
temperature increase of the engine
coolant, it is not possible to change to
the Sport Sharp (S#) mode. While the
vehicle is in the Sport Sharp (S#) mode,
it changes to the Sport (S) mode when
the engine coolant temperature in-
creases.
. While the engine is cool, you cannot
change to Sport Sharp (S#) mode. Limited slip differential (LSD)
(STI) The LSD provides optimum distribution of
power according to the difference in
revolutions between the right and left
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads or when high speed
driving.
CAUTION. Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
. If one tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely
affect the LSD.
. If you use a temporary spare tire
to replace a flat tire, be sure to
use the original temporary spare
tire stored in the vehicle. Using
other sizes will adversely affect
the LSD. Power steering & STI The vehicle is equipped with a hydraulic
power steering system. The power steer-
ing system operates only when the engine
is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.
CAUTIONDo not hold the steering wheel at the
fully locked position left or right for
more than 5 seconds. This may
damage the power steering pump.
NOTE Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is
normal. It does not indicate power
steering system trouble.Starting and operating/Limited slip differential (LSD) (STI)

hicle is stationary. 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 minutes 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 un-
able to monitor all four road
wheels. Contact your SUBARU
dealer as soon as possible for
tire and sensor replacement and/
or system 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 trunk. This may cause
poor reception of the signals from
the tire pressure sensors, and the
tire pressure monitoring system will
not function properly. FCC ID: CWTWD1U781

Maintenance and service/Tires and wheels
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 approximately
one 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.
WARNINGIf 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
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 minute,
promptly contact a SUBARU dealer
to have the system inspected.
& Tire inspection Check on a daily basis that the tires are
free from serious damage, nails, and
stones. At the same time, check the tires
for abnormal wear.
Contact your SUBARU dealer immedi-
ately if you find any problem.
NOTE . When the wheels and tires strike
curbs or are subjected to harsh treat-
ment as when the vehicle is driven on a
rough surface, they can suffer damage11-32

Maintenance and service/Tires and wheels
& Tire rotation direction mark
Example of tire rotation direction mark
1) Front
If the tire has the rotation direction
specification, the tire rotation direction
mark is placed on its sidewall.
When you install a tire that has the tire
rotation direction mark, install the tire with
the direction mark facing forward. & Tire rotation
Vehicles equipped with 4 non-unidirec-
tional tires
1) Front
Vehicles equipped with unidirectional tires
1) Front Tire wear varies from wheel to wheel.
Move the tires to the positions shown in
the illustration each time they are rotated.
For the tire rotation schedule, refer to the
“ Warranty and Maintenance Booklet ” .
Replace any damaged or unevenly worn
tires at the time of rotation. After tire
rotation, adjust the tires pressures and
make sure the wheel nuts are correctly
tightened.
After driving approximately 600 miles
(1,000 km), check the wheel nuts again
and retighten any nut that has become
loose.
& Tire replacement The wheels and tires are important and
integral parts of your vehicle ’ s design;
they cannot be changed arbitrarily. The
tires fitted as standard equipment are
optimally matched to the characteristics
of the vehicle and were selected to give
the best possible combination of running
performance, ride comfort, and service
life. It is essential for every tire to have a
size and construction matching those
shown on the tire placard and to have a
speed symbol and load index matching
those shown on the tire placard.
Using tires of a non-specified size detracts11-36

from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle ’ sground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern), con-
struction, and size. You are advised to
replace the tires with new ones that are
identical to those fitted as standard equip-
ment.
For safe vehicle operation, SUBARU
recommends replacing all four tires at
the same time.
WARNING. When replacing or installing
tire(s), all four tires must be the
same for the following items.
(a) Size
(b) Circumference
(c) Speed symbol
(d) Load index
(e) Construction
(f) Manufacturer
(g) Brand (tread pattern)
(h) Degrees of wear For items (a) to (d), you must
obey the specification that is
printed on the tire placard. The
tire placard is located on the
driver ’ s door pillar.
If all four tires are not the same in
items (a) to (h), there is a possi-
bility that it may lead to serious
mechanical damage to the drive
train of your car and affect the
following factors.
— Ride
— Handling
— Braking
— Speedometer/Odometer
calibration
— Clearance between the body
and the tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
. Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires.
Doing so can dangerously re-
duce controllability, resulting in
an accident. & Wheel replacement When replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from SUBARU dealers.
WARNINGUse only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of
vehicle control could lead to an
accident.
NOTE When any of the wheels are removed
and replaced for tire rotation or to
change a flat tire, always check the
tightness of the wheel nuts after driv-
ing approximately 600 miles (1,000 km).
If any nut is loose, tighten it to the
specified torque. Maintenance and service/Tires and wheels
11-37

Maintenance and service/Aluminum wheels
Aluminum wheels Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
. When any of the wheels are removed
and replaced for tire rotation or to change
a flat tire, always check the tightness of
the wheel nuts after driving approximately
600 miles (1,000 km). If any nut is loose,
tighten it to the specified torque.
. Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
. Never let the wheel rub against sharp
protrusions or curbs.
. When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for aluminum wheels. Windshield washer fluid CAUTIONNever use engine coolant as washer
fluid because it could cause paint
damage.
When there is only a small amount of
washer fluid remaining, the windshield
washer fluid warning indicator will illumi-
nate. When this occurs, refill the washer
fluid as follows. Remove the washer tank filler cap, then
add windshield washer fluid until it
reaches the “ FULL ” mark on the tank. If
windshield washer fluid is unavailable use
clean water.
In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid. SUBARU Windshield Washer Fluid
contains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the following
table.11-38
