2006 SUBARU LEGACY oil temperature

8-28 Driving tips
sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle’s brakes. Do not
make sudden downshifts. yWhen driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. y When driving uphill in hot weather, pay
attention to the water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT vehicles) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air con-
ditioner and stop the vehicle at the nearest
safe place. Refer to the “Engine overheat-
ing” section in chapter 9, and “Warning
and indicator lights” section in chapter 3.
NOTE
With AT vehicles, the temperature of
engine coolant is less likely to rise to
the OVERHEAT zone in the “D” posi-
tion than in the manual mode position. y If your vehicle has an automatic trans-
mission, avoid using the accelerator pedal
to stay stationary on an uphill slope in-
stead of using the parking brake or foot
brake. That may cause the transmission fluid to overheat. T
Parking on a grade
Always block the wheels under both vehi-
cle and trailer when parking. Apply the
parking brake firmly. You should not park
on a hill or slope. But if parking on a hill or
slope cannot be avoided, you should take
the following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, re-
lease the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then ap-
ply the parking brake; slowly release the
regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P” (automatic transmis-
sion) and shut off the engine.

9-12 In case of emergency
5. Start the engine of the vehicle with the
booster battery and run it at moderate
speed. Then start the engine of the vehi-
cle that has the discharged battery.
6. When finished, carefully disconnect the
cables in exactly the reverse order.Engine overheating
If the engine overheats, pull off the road
safely and stop the vehicle in a safe place. „If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down. „ If no steam is coming from
the engine compartment
1. Keep the engine running at idling
speed.
2. Open the hood to ventilate the engine compartment.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays at the
overheated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank.
If the coolant level is below the “MIN”
mark, add coolant up to the “MAX” mark.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
is under pressure. Removing the
cap while the engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.

11 - 1 2 Maintenance and service
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.

*: 5W-30 is preferred.
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.

Power steering fluid „Checking the fluid level
The power steering fluid expands greatly
as its temperature rises; the fluid level dif-
fers according to fluid temperature. There-
fore, the reservoir tank has two different
checking ranges for hot and cold fluids.
Check the power steering fluid level
monthly.
1. Park the vehicle on a level surface, and
stop the engine.
2. Check the fluid level of the reservoir
tank.
When the fluid is hot after the vehicle has
been run: Check that the oil level is be-
tween “HOT MIN” and “HOT MAX” on the
surface of the reservoir tank.
When the fluid is cool before the vehicle is
run: Check that the oil level is between
“COLD MIN” and “COLD MAX” on the sur-
face of the reservoir tank.
3. If the fluid level is lower than the appli-
cable “MIN” line, add the recommended
fluid as necessary to bring the level be-
tween the “MIN” and “MAX” line. If the fluid level is extreme low, it may indi-
cate possible leakage. Consult your
SUBARU dealer for inspection. „
Recommended fluid
“Dexron III” Type Automatic Transmis-sion Fluid
Be careful not to burn yourself be-
cause the fluid may be hot. yWhen power steering fluid is be-
ing added, use only clean fluid,
and be careful not to allow any dirt
into the tank. And never use dif-ferent brands together.
y Avoid spilling fluid when adding it
in the tank.

y Be careful not to spill power steer-
ing fluid when adding it. If power
steering fluid touches the exhaust
pipe, it may cause a bad smell,
smoke, and/or a fire. If power
steering fluid gets on the exhaust
pipe, be sure to wipe it off.
