2014 SUBARU IMPREZA WRX torque

11-30Maintenance and service/Tires and wheels
Using tires of a non-specified size detracts
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
size, circumference, speed symbol, load
index, construction, manufacturer, brand
(tread pattern), and degrees of wear. You
are advised to replace the tires with new
ones that are identical to those fitted as
standard equipment.
For safe vehicle operation, SUBARU
recommends replacing all four tires at
the same time.
WARNING
. When you replacing or installing
tire(s), all four tires must be the
same for 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 the items (a) to (d), you must
obey the specification that is
printed on the tire placard. The
tire placard is located on the
bottom of driver
’s door pillar.
If all of four tires are not the same
for items (a) to (h), there is a
possibility that serious mechan-
ical damage could occur to the
drive train of your car, and affect
the following. — Ride
— Handling
— Braking
— Speedometer/Odometer
calibration— Clearance between the body
and 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.
WARNING
Use 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 anaccident.
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.

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
If you spray washer fluid on the windshield
but the supply of washer fluid appears to
diminish, check the level of washer fluid in
the tank.
Washer fluid level gauge
Remove the washer tank filler cap, then
check the fluid level indicated by the level
gauge (attached to the inside of the cap).
If the level is near the
“Low ”mark, add
fluid until it reaches the “Hi ”level on the

&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
vehiclecontrolcanleadtoanaccident. . To maximize the life of each tire
and ensure that the tires wear
uniformly, it is best to rotate the
tires every 7,500 miles (12,000 km).
For information about the tire rota-
tion order, refer to “Tire rotation ”
F 11-29 .
Replace any damaged or
unevenly worn tires at the time of rotation. After tire rotation, adjust
the tire pressures and make sure
the wheel nuts are correctly tigh-
tened. For information about the
tightening torque and tightening
sequence for the wheel nuts, refer to
“Flat tires ”F 9-5 .
& 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 trailer hitch, roof rack or bike carrier, etc., and the tongue load of
a trailer. Therefore cargo capacity
can be calculated by the following method.
Cargo capacity = Load limit
(total
weight of occupants + total weight
of optional equipment + tongue
load of a trailer (if applicable))
For information about vehicle load-
ing, refer to “Loading your vehicle ”
F 8-10 .
NOTE
Your vehicle is neither designed
nor intended to be used for
trailer towing. Therefore, never
tow a trailer with your vehicle.
