2016 SUBARU IMPREZA fuel cap

Clear away ice and snow that has
accumulated under the fenders to avoid
making steering difficult. During severe
winter driving, stop when and where it is
safe to do so and check under the fenders
periodically.
!Parking in cold weather
WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the engine
running.
CAUTION
.Do not use the parking brake
when parking for long periods in
cold weather since it could freeze
in that position.
. When the vehicle is parked in
snow or when it snows, raise the
wiper blades off the glass to
prevent damage to them.
. When the vehicle has been left
parked after use on roads heavily
covered with snow, or has been
left parked during a snowstorm, icing may develop on the brake
system, which could cause poor
braking action. Check for snow
or ice buildup on the suspension,
disc brakes and brake hoses
underneath the vehicle. 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
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-

information on braking on slippery sur-
faces, refer to “ABS (Anti-lock Brake
System) ”F 7-32 and “Vehicle Dynamics
Control system ”F 7-34.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of

ious injury.
CAUTION
Do not carry spray cans, containers
with flammable or corrosive liquids
or any other dangerous items inside
the vehicle.
NOTE
For better fuel economy, do not carry
unneeded cargo.
&Vehicle capacity weight
Vehicle placard
The load capacity of your vehicle is
determined by weight, not by available
cargo space. The maximum load you can
carry in your vehicle is shown on the
vehicle placard attached to the driver ’s
side door pillar. It includes the total weight
of the driver and all passengers and their
belongings, any optional equipment such
as a trailer hitch, roof rack or bike carrier,
etc., and the tongue load of a trailer.
& GVWR and GAWR (Gross
Vehicle Weight Rating and
Gross Axle Weight Rating)
Certification label
The certification label attached to the
bottom of driver ’s side door pillar shows
GVWR (Gross Vehicle Weight Rating) and
GAWR (Gross Axle Weight Rating).
The GVW (Gross Vehicle Weight) must
never exceed the GVWR. GVW is the
combined total of weight of the vehicle,
fuel, driver, all passengers, luggage, any
optional equipment and trailer tongue
load. Therefore, the GVW changes de-
pending on the situation. The GVWR
equals Curb Weight (actual weight of your
vehicle –including standard equipment,
fluids, emergency tools and spare tire

maximum gross weight. The chains
should cross under the trailer tongue to
prevent the tongue from dropping onto the
ground in case it should disconnect from
the hitch ball. Allow sufficient slack in the
chains taking tight turn situations into
account; however, be careful not to let
them drag on the ground.
WARNING
Do not connect safety chains to any
part of the vehicle other than the
safety chain hooks.
Hitch harness connector
8. Connect the hitch wire harness’s black
four-pin wire connector to the towing
trailer ’s wire harness. 9. Confirm proper function of the hitch
wire harness by individually activating the
brake, stop and turn signal lights on the
trailer.
NOTE
Always disconnect the trailer wire har-
ness before launching or retrieving a
watercraft.
&
If not towing a trailer
. Remove the ball mount from the hitch
receiver tube and insert the receiver cover
onto the hitch receiver tube.
. Place the dust cap over the four-pin
connector of the hitch wire harness to
protect against possible damage.
. Occasionally lubricate terminals of the
four-pin connector using terminal grease.
Trailer towing (Crosstrek
models)
CAUTION
This “Trailer towing ”section is
applicable for Crosstrek models.
Other vehicle models are neither
designed nor intended to be used
for trailer towing. Therefore, never
tow a trailer with other vehicle
models.
Your vehicle is designed and intended to
be used primarily as a passenger-carrying
vehicle. Towing a trailer puts additional
loads on your vehicle’ s engine, drivetrain,
brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safety
and satisfaction depend upon proper use
of correct equipment and cautious opera-
tion of your vehicle. Seek the advice of
your SUBARU dealer to assist you in
purchasing a hitch and other necessary
towing equipment appropriate for your
vehicle. Do not use towing equipment
other than genuine SUBARU towing
equipment. In addition, be sure to follow
the instructions for proper installation and
use provided by the trailer or caravan ’s

Maintenance and service/Engine oil
Engine oil
CAUTION
.If the level gauge cannot be
pulled out easily, twist the level
gauge right and left, then gently
pull it out. Otherwise, you may be
injured accidentally straining
yourself.
. Use only engine oil with the
recommended grade and vis-
cosity.
. 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. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
& Engine oil consumption
Some engine oil will be consumed while
driving. The rate of consumption can be
affected by such factors as transmission
type, driving style, terrain and tempera-
ture. Under the following conditions, oil
consumption can be increased and thus
require refilling between maintenance
intervals:
. When the engine is new and within the break-in period
.
When the engine oil is of lower quality
. When the incorrect oil viscosity is used
. When engine brakin g is employed
(repeatedly)
. When the engine is operated at high
engine speeds (for extended periods of
time)
. When the engine is operated under
heavy loads (for extended periods of time)
. When towing a trailer (Crosstrek mod-
els)
. When the engine idles for extended
periods of time
. When the vehicle is operated in stop
and go and/or heavy traffic situations
. When the vehicle is used under severe
thermal conditions
. When the vehicle accelerates and
decelerates frequently
Under these or similar conditions, you
should check your oil at least every 2nd
fuel fill-up and change your engine oil
more frequently. Different drivers in the
same car may experience different results.
If your oil consumption rate is greater than
expected, contact your authorized
SUBARU retailer who may perform a test
under controlled conditions.

&Checking the oil level
1. Park the vehicle on a level surface and
turn the ignition switch to the “LOCK”/
“OFF ”position. If you check the oil level
just after turning the ignition switch to the
“LOCK ”/“OFF ”position, wait a few minutes
for the oil to drain back into the oil pan
before checking the level.
2. Pull out the level gauge, wipe it clean,
and insert it again.
3. Be sure the level gauge is correctly

Maintenance and service/Cooling system
&Recommended grade and
viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Refer to “Engine oil ”F 12-4.
NOTE
Engine oil viscosity (thickness) 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 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.

&
Safety precautions
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
11-10

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 11-35 and “Fuse panel
located in the engine compartment ”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
the cooling system and connections be
checked for leaks, damage, or looseness.

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.
