2016 SUBARU WRX wheel

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

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

Maintenance and service/Replacing bulbs
the headlight assembly by turning it clock-
wise.

NOTE . If headlight aiming is required, con-
sult your SUBARU dealer for proper
adjustment of the headlight aim.
. It may be difficult to replace the

Consumer information and Reporting safety defects/Tire information
& Tire care – maintenance and
safety practices.
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. .
Inspect the tire tread regularly
and replace the tires before their
tread wear indicators become visi-
ble. When a tire ’ streadwear
indicator becomes visible, the tire
is worn beyond the acceptable limit
and must be replaced immediately.
With a tire in this condition, driving
at even low speeds in wet weather
can cause the vehicle to hydro-
plane. Possible resulting loss of
vehiclecontrolcanleadtoan
accident. .
Replace any damaged or un-
evenly worn tires at the time of
rotation. For information about the
tire rotation order, refer to “ Tire
rotation ” F 11-36 .
After tire rotation,
adjust the tire pressures and make
sure the wheel nuts are correctly
tightened. For information about the tightening torque and tighten-
ing sequence for the wheel nuts,
refer to “ Flat tires ” F 9-4 .
& Vehicle load limit – how to
determine
The load capacity of your vehicle is
determined by weight, not by avail-
able cargo space. The load limit of
your vehicle is shown on the
vehicle placard attached to the
driver ’ s side B-pillar. Locate the
statement “ The combined weight
of occupants and cargo should
never exceed XXX kg or XXX lbs ”
on your vehicle ’ s placard.
Thevehicleplacardalsoshows
seating capacity of your vehicle.
The total load capacity includes the
total weight of driver and all pas-
sengers and their belongings, any
cargo, any optional equipment such
as a roof rack or bike carrier, etc.
Therefore cargo capacity can be
calculated by the following method.
Cargo capacity = Load limit − (total weight of occupants + total weight
of optional equipment)
For information about vehicle load-
ing, refer to “ Loading your vehicle ”
