2014 SUBARU IMPREZA WRX brake

CAUTION
. Be careful not to damage brake
hoses, sensor harnesses, and
other parts when washing sus-
pension components.
. Be careful not to flush the engine
bottom for a long time. It may
cause damage of some electricalparts.
! Using a warm water washer
. Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle. . Do not wash the same area continu-
ously.. If a stain will not come out easily, wash
by hand. Some warm water washers are
of the high temperature, high pressure
type, and they can damage or deform the
resin parts such as moldings, or cause
water to leak into the vehicle.
& Waxing and polishing
Always wash and dry the vehicle before
waxing and polishing.
Use a good quality polish and wax and
apply them according to the manufac-turer ’s instructions. Wax or polish when
the painted surface is cool. Be sure to polish and wax the chrome trim,
as well as the painted surfaces. Loss of
wax on a painted surface leads to loss of
the original luster and also quickens the
deterioration of the surface. It is recom-
mended that a coat of wax be applied at
least once a month, or whenever the
surface no longer repels water.
If the appearance of the paint has dimin-
ished to the point where the luster or tone
cannot be restored, lightly polish the
surface with a fine-grained compound.
Never polish just the affected area, but
include the surrounding area as well.
Always polish in only one direction. A
No. 2000 grain compound is recom-
mended. Never use a coarse-grained
compound. Coarse-grained compounds
have a smaller grain-size number and
could damage the paint. After polishing
with a compound, coat with wax to restore
the original luster. Frequent polishing with
acompoundoranincorrectpolishing
technique will result in removing the paint
layer and exposing the undercoat. When
in doubt, it is always best to contact your
SUBARU dealer or an auto paint specia-list.
CAUTION
Do not use any agents with organic solvents on the surface of the bulb
assembly cover. However, if a polish
or wax with organic solvents is
applied to the cover surface, com-
pletely wipe off the polish or wax.
Otherwise, the cover surface may bedamaged.
NOTE
Be careful not to block the windshield
washer nozzles with wax when waxing
the vehicle. & Cleaning aluminum wheels
. Promptly wipe the aluminum wheels
clean of any kind of grime or agent. If dirt
is left on too long, it may be difficult to
clean off. . Do not use soap containing grit to
clean the wheels. Be sure to use a neutral
cleaning agent, and later rinse thoroughly
with water. Do not clean the wheels with a
stiff brush or expose them to a high-speed
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 otheragents.

10-4Appearance care/Corrosion protection
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 reliableoperation. &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 of maintenance and treatment if you needassistance.
Repair chips and scratches in the paint as
soon as you find them.
Check the interior of the vehicle for water
and dirt accumulation under the floor mats
because that could cause corrosion.
Occasionally check under the mats to
make sure the area is dry.
Keep your garage dry. Do not park your
vehicle in a damp, poorly ventilated
garage. In such a garage, corrosion can
be caused by dampness. If you wash the
vehicle in the garage or put the vehicle
into the garage when wet or covered with
snow, that can cause dampness.
If your vehicle is operated in cold weather
and/or in areas where road salts and other
corrosive materials are used, the door
hinges and locks, trunk lid lock, and hood
latch should be inspected and lubricated
periodically.

11-4Maintenance and service/Maintenance precautions
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.
. Do not tamper with the wiring of
the SRS airbag system or seat-
belt pretensioner system, or at-
tempt to take its connectors
apart, as that may activate the
system or it can render it inop-
erative. NEVER use a circuit
tester for this wiring.
If your SRS airbag or seatbelt
pretensioner needs service, con-
sult your nearest SUBARU deal-
er. &
Before checking or servicing
in the engine compartment
WARNING
. Always stop the engine and set
the parking brake firmly to pre-
vent the vehicle from moving.
. Always let the engine cool down.
Engine parts become very hot
when the engine is running and
remain hot for some time after
the engine is stopped.
. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
. Always remove the key from the
ignition switch. When the ignition
switch is in the “ON ”position,
thecoolingfanmayoperate
suddenly even when the engine
is stopped.
. Before performing any servicing
on a vehicle equipped with a
remote engine start system (a
dealer option) temporarily place
that system in the service mode
to prevent it from unexpectedly
starting the engine. &
When checking or servicing
in the engine compartment
CAUTION
Do not contact the belt cover while
checking the components in the
engine compartment. Doing so may
cause your hand to slip off the belt
cover and result in an unexpected
injury.
