2017 SUBARU FORESTER low oil pressure

Maintenance and service/Cooling system
in hot weather, oil of higher viscosity is
required to properly lubricate the en-
gine.
&Synthetic oil
You should use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using
synthetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner ’s Manual. Refer to “Engine
oil ”F 12-4. Also, you must follow the oil
and filter changing intervals shown in the
Warranty and Maintenance booklet.
NOTE
Synthetic oil of the grade and viscosity
noted in chapter 12 is the recom-
mended engine oil for optimum engine
performance. Conventional oil may be
used if synthetic oil is unavailable.
Cooling system
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap is
removed.
CAUTION
. Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). This coolant
should not be mixed with any
other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. Should it be
necessary to top up the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand or type, the maintenance interval is
shortened to that of the mixing
coolant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Cooling fan, hose and con-
nections
Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the coolant temperature high
warning light blinks or illuminates in RED,
the cooling fan circuit may be defective.
Refer to “Coolant temperature low indica-
tor light/Coolant temperature high warning
light ”F 3-17.
Check the fuse and replace it if necessary.
Refer to “Fuses”F 11-37 and “Fuses and
circuits ”F 12-12.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
11-12

the cooling system and connections be
checked for leaks, damage, or looseness.
&Engine coolant
! Checking the coolant level
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap is
removed.
1) “FULL ”level mark
2) “LOW ”level mark
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the
“LOW ”level mark, add coolant up to the
“FULL ”level mark. If the reserve tank is
empty, remove the radiator cap and refill
coolant up to just below the filler neck as
shown in the following illustration.
1) Fill up to this level
3. After refilling the reserve tank and the
radiator, reinstall the cap and check that
the rubber gaskets inside the radiator cap
are in the proper position.

GAS STATION REFERENCE
&
Fuel:
! Non-turbo models
Use only unleaded gasoline with an octane rating of 87 AKI
(90 RON) or higher .
! Turbo models
Unleaded gasoline with an octane rating of 93 AKI (98 RON)
or higher is recommended. Unleaded gasoline with an octane
rating of 91 AKI (95 RON) or higher may be used with no
detriment to engine durability or driveability. However, you may
notice a slight decrease in maximum engine performance while
using 91 AKI (95 RON) fuel. If unleaded gasoline with an octane
rating of 91 AKI (95 RON) is not available, refer to “Fuel
requirements ”F 7-3.
&Fuel octane rating:
! RON
This octane rating is the Research Octane Number.
! AKI
This octane rating is the average of the Research Octane and
Motor Octane numbers and is commonly referred to as the Anti
Knock Index (AKI).
&Fuel capacity:
15.9 US gal (60 liters, 13.2 Imp gal)
&Engine oil:
Use only the following oils.
. API classification SN with the words “RESOURCE CON-
SERVING ”
. or ILSAC GF-5, which can be identified with the ILSAC
certification mark (Starburst mark)
For the complete viscosity requirements, refer to “Engine oil”
F 12-4.
&Engine oil capacity:
Non-turbo models: 5.1 US qt (4.8 liters, 4.2 Imp qt)
Turbo models: 5.4 US qt (5.1 liters, 4.5 Imp qt)
The indicated oil quantity is only a guideline and is estimated
based on a case when the engine oil is changed with an oil
filter. After refilling the engine with oil, the oil level should be
checked using the oil level gauge. For more details about
maintenance and service, refer to “Engine oil”F 11-10.
&Cold tire pressure:
Refer to “Tires ”F 12-10.
