2007 SUBARU IMPREZA WRX stop start

9-8In case of emergency
illustration.
The torque for tightening the nuts is 58 to
72 lbf·ft (80 to 100 N·m, 8 to 10 kgf·m).
This torque is equivalent to applying
approximately 88 to 110 lbs (40 to 50 kg)
at the top of the wheel nut wrench. Never
use your foot on the wheel nut wrench or a
pipe extension on the wrench because
you may exceed the specified torque.
Have the wheel nut torque checked at
the nearest automotive service facility.
14. Store the flat tire in the spare tire compartment.
Put the spacer and tighten the attaching
bolt firmly.
Also store the jack and wheel nut wrench
in their storage locations.
After placing the jack in its storage
location, turn the jackscrew clockwise by
hand until it becomes too hard to turn.
Then, tighten it by an additional 1/4 –1/3
of a turn using a screwdriver or the jack
handle. Unless the jack is properly se-
cured, it may rattle while the vehicle ismoving.
WARNING
Never place a tire or tire changing
tools in the passenger compartment
after changing wheels. In a sudden
stop or collision, loose equipment
could strike occupants and cause
injury. Store the tire and all tools in
the proper place. Jump starting
WARNING
. Battery fluid is SULFURIC ACID.
Do not let it come in contact with
the eyes, skin, clothing or thevehicle.
If battery fluid gets on you,
thoroughly flush the exposed
area with water immediately. Get
medical help if the fluid has
entered your eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water,
and obtain immediate medicalhelp.

dren away from the battery.
. The gas generated by a battery
explodes if a flame or spark is
brought near it. Do not smoke or
light a match while jump starting.
. Never attempt jump starting if the
discharged battery is frozen. It
could cause the battery to burst
or explode.
. Whenever working on or around
a battery, always wear suitable

7. Remove the oil filter with an oil filter wrench.
8. Before installing a new oil filter, apply a
thin coat of engine oil to the seal.
9. Clean the rubber seal seating area of
the bottom of engine and install the oil
filter by hand turning. Be careful not to
twist or damage the seal.
10. Tighten the oil filter by the amount
indicated in the following table after the
seal makes contact with the bottom of engine. Oil filter color Part number
Amount of
rotation
Black 15208AA100 1 rotation
White 15208AA09A 2/3
–3/4
rotation
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.

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.
6. Pour the coolant and fill to the reser-
voir tank ’s “FULL ”level mark.
1) Rubber gaskets
7. Put the radiator cap back on and
tighten firmly. At this time, make sure that
the rubber gasket in the radiator cap is
correctly in place.
8. Start and run the engine for more than
five minutes at 2,000 to 3,000 rpm.
9. Stop the engine and wait until the coolant cools down (122 to 140
8F [50 to
60 8C]). If there is any loss of coolant, add
coolant to the radiator ’s filler neck and to
the reserve tank ’s “FULL ”level.
10. Put the radiator cap and reservoir cap
back on and tighten firmly. Air cleaner element
The air cleaner element functions as a
filter screen. When the element is perfo-
rated or removed, engine wear will be
excessive and engine life shortened.
The air cleaner element is a viscous type.
It is unnecessary to clean or wash theelement.
WARNING
Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters
intake air but also stops flames if
the engine backfires. If the air
cleaner element is not installed
when the engine backfires, you
could be burned.
& Replacing the air cleaner element
Replace the air cleaner element according
to the maintenance schedule in the“ Warranty and Maintenance Booklet ”. Un-
der extremely dusty conditions, replace it
more frequently. It is recommended that
you always use genuine SUBARU parts. Maintenance and service

same brand. Brake booster
If the brake booster does not operate as
described in the following, have it checked
by your SUBARU dealer.
1. With the engine off, depress the brake
pedal several times, applying the same
pedal force each time. The distance the
pedal travels should not vary.
2. With the brake pedal depressed, start
the engine. The pedal should move
slightly down to the floor.
3. With the brake pedal depressed, stop
the engine and keep the pedal depressed
for 30 seconds. The pedal height should
not change.
4. Start the engine again and run for
approximately one minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake
booster operates properly if the pedal
stroke decreases with each depression. Brake pedal
Check the brake pedal free play and
reserve distance according to the main-
tenance schedule in the
“Warranty and
Maintenance Booklet ”.
& Checking the brake pedal
free play
1) 0.04 –0.12 in (1.0 –3.0 mm)
Stop the engine and firmly depress the
brake pedal several times. Lightly press
the brake pedal down with one finger to
check the free play with a force of less
than 2 lbs (10 N, 1 kg).
If the free play is not within proper
specification, contact your SUBARU deal-
er. Maintenance and service
