2006 SUBARU IMPREZA oil change

1-18 Seat, seatbelt and SRS airbags
1. Insert a key or other hard pointed ob-
ject into the slot in the connector (buckle)
on the right-hand side and push it in, and
the connector (tongue) plate will discon-
nect from the buckle.
2. Allow the retractor to roll up the belt. You should hold the webbing end and
guide it back into the retractor while it is
rolling up. Insert the tongue plate into the
belt holder.
Seatbelt maintenance
To clean the seatbelts, use a mild soap
and lukewarm water. Never bleach or dye
the belts because this could seriously af-
fect their strength.
Inspect the seatbelts and attachments in-
cluding the webbing and all hardware pe-
riodically for cracks, cuts, gashes, tears,
damage, loose bolts or worn areas. Re-
place the seatbelts even if only minor
damage is found.

Do not allow the retractor to roll
up the seatbelt too quickly. Other-
wise, the metal tongue plates may
hit against the trim, resulting in
damaged trim.
Have the seatbelt fully rolled up
so that the tongue plates are neat-
ly stored. A hanging tongue plate
can swing and hit against the trim
during driving, causing damage to
the trim.
100290Keep the belts free of polishes,
oils, chemicals and particularly
battery acid.
Never attempt to make modifica-
tions or changes that will prevent
the seatbelt from operating prop-
erly.

11-8 Maintenance and service
Engine oil
Checking the oil level
Check the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again.
3. Be sure the dipstick is correctly insert-
ed until it stops with the graphic
symbol on its top appearing as
shown in the illustration.
1) Notch
2) Upper level
3) Lower level
4. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the up-
per level.
If you check the oil level just after stopping
the engine, wait a few minutes for the oil to
drain back into the oil pan before checking
the level.
Just after driving or while the engine is
warm, the engine oil level reading may be
in a range between the upper level and
the notch mark. This is caused by thermal
expansion of the engine oil.
To prevent overfilling the engine oil, do not
add any additional oil above the upper lev-
el when the engine is cold.
Changing the oil and oil filter
Change the oil and oil filter according to
the maintenance schedule in the “Warran-
ty and Maintenance Booklet ”.
The engine oil and oil filter must be
changed more frequently than listed in the
maintenance schedule when driving on
dusty roads, when short trips are frequent-
ly made, or when driving in extremely cold
whether.
1. Warm up the engine by letting the en-
gine idle for approximately 10 minutes to
ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine.
3. Remove the oil filler cap.
B00467
Use only engine oil with the rec-
ommended grade and viscosity.
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. If en-
gine oil gets on the exhaust pipe,
be sure to wipe it off.

3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.
Changing the coolant
Always add genuine Subaru cooling sys-
tem conditioner whenever the coolant is
replaced.
Change the engine coolant and add gen-
uine Subaru cooling system conditioner
using the following procedures according
to the maintenance schedule.
1. Remove the under cover.
2. Place a proper container under the
drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the
coolant from the radiator. Then drain the
coolant from the reserve tank. Tighten the
drain plug securely.
NOTE (Turbo model only)
The cap (without tabs) on top of the ra-
diator does not need to be removed. To add coolant, remove the cap (with tabs)
on the coolant tank on top of the en-
gine.
4. Install the under cover.
Non-turbo models
1) Filler neck
2) Fill up to this level
Be careful not to spill engine cool-
ant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on the
exhaust pipe, be sure to wipe it
off.
Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
B00018
B00019
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.

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 is removed and
replaced for tire rotation or to change a
flat, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose, tight-
en 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.
Be sure to fit tire chains on uniformly
and completely around the tire, otherwise
the chains may scratch the wheel.
When wheel nuts, balance weights, or
the center cap is replaced, be sure to re-
place them with genuine SUBARU parts
designed for aluminum wheels.
Intercooler water spray
(WRX-STI)
Add water to the intercooler water spray
tank when the intercooler water spray
warning light in the combination meter
comes on. The warning light comes on
when the water in the tank has decreased
to approximately 0.4 liters (0.4 US qt, 0.4
Imp qt). The tank is located on the right-hand side
of the trunk.
NOTE
Use only pure water for refilling.
In cold weather (when you do not use
the intercooler water spray), keep the
tank half-empty in case the water freez-
es. A larger amount of water could
break the tank if it froze.
