fuel additives SUBARU OUTBACK 2017 6.G Owners Manual

Starting and operating/Fuel
additives will help prevent deposits from
forming in your engine and fuel system.
This helps keep your engine in tune and
your emission control system working
properly, and is a way of doing your part
for cleaner air. If you continuously use a
high quality fuel with the proper detergent
and other additives, you should never
need to add any fuel system cleaning
agents to your fuel tank.
Many gasolines are now blended with
materials called oxygenates. Use of these
fuels can also help keep the air cleaner.
Oxygenated blend fuels, such as MTBE
(Methyl Tertiary Butyl ether) or ethanol
(ethyl or grain alcohol) may be used in
your vehicle, but should contain no more
than 15% MTBE or 10% ethanol for the
proper operation of your SUBARU.
Do not use any gasoline that contains
more than 10% ethanol, including from
any pump labeled E15, E30, E50 or E85
(which are only some examples of fuel
containing more than 10% ethanol).
In addition, some gasoline suppliers are
now producing reformulated gasolines,
which are designed to reduce vehicle
emissions. SUBARU approves the use of
reformulated gasoline.
If you are not sure what the fuel contains,you should ask your service station
operators if their gasolines contain deter-
gents and oxygenates and if they have
been reformulated to reduce vehicle emis-
sions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following.
.
Fuel should be unleaded and have an
octane rating no lower than that specified
in this manual.
. Methanol (methyl or wood alcohol) is
sometimes mixed with unleaded gasoline.
Methanol can be used in your vehicle
ONLY if it does not exceed 5% of the fuel
mixture ANDif it is accompanied by
sufficient quantities of the proper cosol-
vents and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanol EXCEPT
under these conditions.
. If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a different brand of gaso-
line before seeking service at your
SUBARU dealer.
. Fuel system damage or driveability
problems which result from the use of
improper fuel are not covered under the
SUBARU Limited Warranty.& Fuel filler lid and cap
! Refueling
Only one person should be involved in
refueling. Do not allow others to approach
the area of the vehicle near the fuel filler
pipe while refueling is in progress.
Be sure to observe any other precautions
that are posted at the service station.
1. Stop the vehicle and turn off the
engine.
2. To open the fuel filler lid, pull the lid
release lever up. The lever is on the floor
at the left of the driver ’s seat.

Driving tips/Winter driving
–When the vehicle has been left
parked during a snowstorm
Check for snow or ice buildup on the suspension, disc brakes and
brake hoses underneath the ve-
hicle. If there is caked snow or
ice, remove it, being careful not
to damage the disc brakes and
brake hoses and ABS harness.
When parking for long periods in cold
weather, you should observe the following
tips.
1. For MT models, place the shift lever in
the “1”or “R”position. For CVT models,
place the select lever in the “P”position.
2. Use tire stops under the tires to
prevent the vehicle from moving.
! Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an
antifreeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used
for an extended period, it is best to have the fuel tank filled to capacity.

Driving on snowy and icy
roads
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
vehicle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’sintakesystemandmay
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.) Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle
’s braking perfor-
manceonsnowyandicyroads.For
information about braking on slippery
surfaces, refer to “ABS (Anti-lock Brake
System) ”F 7-33 and “Vehicle Dynamics
Control system ”F 7-35.
! Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blade rubbers are not frozen to
the windshield or rear window.
If the wiper blade rubbers are frozen to the
windshield or rear window, perform the
following procedure.
. To thaw the windshield wiper blade
rubbers, use the defroster with the airflow
selection in “
”and the temperature set
for maximum warmth until the wiper blade
rubbers are completely thawed. Refer to
“Climate control ”F 4-1.
. If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blade rubbers. Refer to
“Defogger and deicer ”F 3-61.
. To thaw the rear wiper blade rubbers,
use the rear window defogger. Refer to
“Defogger and deicer ”F 3-61.
