2006 SUBARU LEGACY SAE

8-12 Driving tips
require the use of tire chains, in which
case put the chains on the front wheels
only. Use only SAE class S type chains
that are of the correct size for your tires so
as not to damage the vehicle body or sus-
pension.
When driving with tire chains, drive at
speeds below 19 mph (30 km/h). When a
temporary spare tire is on a front wheel,
replace the temporary spare tire with the
rear tire on the same side of the vehicle,
and then fit chains on the front tires.
Always use the utmost care when driving
with tire chains – overconfidence because
you are driving with tire chains could eas-
ily lead to a serious accident. „ Rocking the vehicle
If you must rock the ve hicle to free it from
snow, sand, or mud, depress the acceler-
ator pedal slightly and move the selector
lever back and forth between “D” and “R”
repeatedly. Do not race the engine. For
the best possible traction, avoid spinning
the wheels when trying to free the vehicle.
When the road surface is extremely slip-
pery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT).
Refer to the “Automatic transmission – 4- speed” and “Automatic transmission – 5-
speed” section in chapter 7 for information
on holding the transmission in 2nd posi-
tion.Loading your vehicle
Never allow passengers to ride on a
folded rear seatback, in the trunk or
in the cargo area. Doing so may re-
sult in serious injury.
y
Never stack luggage or other car-
go higher than the top of the seat-
back because it could tumble for-
ward and injure passengers in the
event of a sudden stop or acci-
dent. Keep luggage or cargo low,
as close to the floor as possible.

Oil capacity (Guideline):
2.5-liter models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
3.0-liter models: 5.8 US qt (5.5 liters, 4.8
Imp qt)
The oil quantity indicated above is only a
guideline. The necessary quantity of oil
depends on the quantity of oil that has
been drained. The quantity of drained oil
differs slightly depen ding on the tempera-
ture 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 nor-
mal 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 engine oil. „ Recommended grade and
viscosity
Oil grade:
ILSAC GF-4, which can be identified
with the ILSAC certification mark
(Starburst mark)
or API classification SM with the
words “ENERGY CONSERVING”
These recommended oil grades can be
identified by looking for either or both of
the following marks displayed on the oil
container.
ILSAC Certification Mark (Starburst Mark) API Service label
1) Indicates the oil quality by API designa-
tions
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving ca- pabilities
In choosing an oil, you want the proper
quality and viscosity, as well as one that
will add to fuel economy. The following ta-
ble lists the recommended viscosities and
applicable temperatures.
When adding oil, different brands may be
used together as long as they are the same API classifica tion and SAE viscosity
as those recommended by SUBARU.
Use only engine oil with the recom-
mended grade and viscosity.

Engine oil viscosity (t hickness) affects fuel
economy. Oils of lower viscosity provide
better fuel economy. However, in hot
weather, oil of higher viscosity is required
to properly lubricate the engine. „ Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in ar-
eas with very high temperatures, or used
for heavy-duty applications such as tow-
ing a trailer, use of oil with the following
grade and viscosities is recommended.

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. yThe cooling system has been
filled at the factory with a high
quality, corrosion-inhibiting, year-
around coolant which provides
protection against freezing down to –33 °F (–36 °C). For adding, use
genuine SUBARU coolant or an
equivalent: a mixture of 50% soft
water and 50% ethylene-glycol ba-
sis coolant. Use of improper cool-
ants may result in corrosion in the
cooling system. It is important to
maintain protection against freez-
ing and corrosion, even if freezing
temperatures are not expected.
Never mix different kinds of cool-
ant.

Maintenance and service 11 - 2 1
Turbo models
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again. 1) Upper level
2) Lower level
3. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil through the dipstick hole to
bring the level up to the upper level.

Be careful not to spill manual trans-
mission oil when adding it. If oil
touches the exhaus t pipe, it may
cause a bad smell, smoke, and/or a
fire. If oil gets on the exhaust pipe,
be sure to wipe it off.
