2007 SUBARU IMPREZA light

Cleaning the interior
Use a soft, damp cloth to clean the climate
control panel, audio equipment, instru-
ment panel, center console, combination
meter panel, and switches. (Do not use
organic solvents.) &Seat fabric
Remove loose dirt, dust or debris with a
vacuum cleaner. If the dirt is caked on the
fabric or hard to remove with a vacuum
cleaner, use a soft brush then vacuum it.
Wipe the fabric surface with a tightly
wrung cloth and dry the seat fabric
thoroughly. If the fabric is still dirty, wipe
using a solution of mild soap and luke-
warm water then dry thoroughly.
If the stain does not come out, try a
commercially-available fabric cleaner. Use
the cleaner on a hidden place and make
sure it does not affect the fabric adversely.
Use the cleaner according to its instruc-tions. NOTE
When cleaning the seat, do not use
benzine, paint thinner, or any similarmaterials. &
Leather seat materials
The leather used by SUBARU is a high
quality natural product which will retain its
distinctive appearance and feel for many
years with proper care.
Allowing dust or road dirt to build up on the
surface can cause the material to become
brittle and to wear prematurely. Regular
cleaning with a soft, moist, natural fiber
cloth should be performed monthly, taking
care not to soak the leather or allow water
to penetrate the stitched seams.
A mild detergent suitable for cleaning
woolen fabrics may be used to remove
difficult dirt spots, rubbing with a soft, dry
cloth afterwards to restore the luster. If
your SUBARU is to be parked for a long
time in bright sunlight, it is recommended
that the seats and headrests be covered,
or the windows shaded, to prevent fading
or shrinkage.
Minor surface blemishes or bald patches
may be treated with a commercial leather
spray lacquer. You will discover that each
leather seat section will develop soft folds
or wrinkles, which is characteristic of
genuine leather. & Synthetic leather upholstery
The synthetic leather material used on the
SUBARU may be cleaned using mild soap or detergent and water, after first vacuum-
ing or brushing away loose dirt. Allow the
soap to soak in for a few minutes and wipe
off with a clean, damp cloth. Commercial
foam-type cleaners suitable for synthetic
leather materials may be used when
necessary. NOTE
Strong cleaning agents such as sol-
vents, paint thinners, window cleaner
or gasoline must never be used on
leather or synthetic interior materials. &
Climate control panel, audio
panel, instrument panel,
console panel, and switches
Use a soft, damp cloth to clean the climate
control panel, audio equipment, instru-
ment panel, center console, combination
meter panel, and switches. NOTE
Do not use organic solvents such as
paint thinners or gasoline, or strong
cleaning agents that contain those solvents. Appearance care

CAUTION
. Never over tighten the oil filter
because that can result in an oil leak.
. Thoroughly wipe off any engine
oil that has spilled over the
exhaust pipe and/or under-cover.
If spilled oil is not promptly
wiped up, the oil could cause afire.
11. Reinstall under cover.
12. Pour engine oil through the filler neck. Oil capacity (guideline): 4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only guideline.
The necessary quantity of oil depends on
the quantity of oil that has been drained.
The quantity of drained oil differs slightly
depending on the temperature of the oil and the time the oil is left flowing out. After
refilling the engine with oil, therefore, you
must use the dipstick to confirm that the
level is correct.
13. Start the engine and make sure that no
oil leaks appear around the filter
’s rubber
seal and drain plug.
14. Run the engine until it reaches the
normal operating temperature. Then stop
the engine and wait a few minutes to allow
the oil drain back. Check the oil level
again and if necessary, add more engineoil.
CAUTION
Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire.

Replacement of brake pad
and lining
The right front disc brake and the right rear
disc brake 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 audible
brake 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 moretimes. ! 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 lbs [147 N, 15kg].)
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 / 44 lbs (196 N, 20 kg)
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. Maintenance and service

tread separation, and destruction of
the tires. The resulting loss of
vehicle control could lead to anaccident.
& Wheel balance
Each wheel was correctly balanced when
your vehicle was new, but the wheels will
become unbalanced as the tires become
worn during use. Wheel imbalance causes
the steering wheel to vibrate slightly at
certain vehicle speeds and detracts from
the vehicle ’s straight-line stability. It can
also cause steering and suspension sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not
correctly balanced, have them checked
and adjusted by your SUBARU dealer.
Also have them adjusted after tire repairs
and after tire rotation. NOTE
Loss of correct wheel alignment*
causes the tires to wear on one side
and reduces the vehicle ’s running
stability. Contact your SUBARU dealer
if you notice abnormal tire wear.
*: The suspension system is designed to hold
each wheel at a certain alignment (relative to
the other wheels and to the road) for optimum
straight-line stability and cornering perfor- mance.
& Wear indicators
1) New tread
2) Worn tread
3) Tread wear indicator
Each tire incorporates a tread wear
indicator, which becomes visible when
the depth of the tread grooves decreases
to 0.063 in (1.6 mm). A tire must be
replaced when the tread wear indicator
appears as a solid band across the tread.
WARNING
When a tire ’s tread wear indicator
becomes visible, the tire is worn
beyond the acceptable limit and
must be replaced immediately. With a tire in this condition, driving at
high speeds in wet weather can
cause the vehicle to hydroplane.
The resulting loss of vehicle control
can lead to an accident.
NOTE
For safety, inspect tire tread regularly
and replace the tires before their tread
wear indicators become visible. & Tire rotation direction markExample 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. Maintenance and service
