NOTE
This light also illuminates when the fuel
filler cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator light illuminating
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure nothing is interfering
with the sealing of the cap. Tightening the
cap will not make the CHECK ENGINE
warning light turn off immediately. It may
take several driving trips. If the light does
not turn off, take your vehicle to your
authorized SUBARU dealer immediately.
!If the light is blinking
If the light is blinking while driving, an
engine misfire condition has been de-
tected which may damage the emission
control system.
To prevent serious damage to the emis-
sion control system, you should do the
following.
. Reduce vehicle speed.
. Avoid hard acceleration.
. Avoid steep uphill grades.
. Reduce the amount of cargo, if possi-
ble.
. If towing a trailer, stop doing so as soon
as possible (trailer towing permitted with
Crosstrek models only). The CHECK ENGINE warning light may
stop blinking and illuminate steadily after
several driving trips. You should have your
vehicle checked by an authorized
SUBARU dealer immediately.

After that, this indicator light/warning light
changes toBLUEand maintains illumina-
tion in BLUE. This BLUEilluminated light
turns off when the engine is warmed up
sufficiently.
If the engine coolant temperature in-
creases over the specified range, the
indicator light/warning light blinks in
RED . At this time, the engine is close to
overheating.
If the engine coolant temperature in-
creases further, the indicator light/warning
light illuminates in REDcontinuously. At
this time, the engine may be overheating.
When the indicator light/warning light
blinks in REDor illuminates in RED, safely
stop the vehicle as soon as possible, and
refer to the emergency steps to take in the
case of engine overheating. Refer to
“Engine overheating ”F 9-13. After that,
have the system checked by your nearest
SUBARU dealer.
Also, if the indicator light/warning light
often blinks in RED, the electrical system
may be malfunctioning. Contact your
SUBARU dealer for an inspection.
NOTE
If the engine is restarted after a certain
driving condition, this indicator light/ warning light may illuminate in RED.
However, this is not a malfunction if the
indicator light/warning light turns off
after a short time.
&Charge warning light
If this light illuminates when the engine is
running, it may indicate that the charging
system is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the alternator belt. If the belt is
loose, broken or if the belt is in good
condition but the light remains illuminated,
contact your nearest SUBARU dealer
immediately.
&Oil pressure warning
light
If this light illuminates when the engine is
running, it may indicate that the engine oil
pressure is low and the lubricating system
is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil is
at the proper level but the light remainsilluminated, contact your nearest
SUBARU dealer immediately.
For details about checking the engine oil
level or adding the engine oil, refer to
“Engine oil
”F 11-8.
CAUTION
Do not operate the engine with the
oil pressure warning light illumi-
nated. This may cause serious en-
gine damage.
&Engine low oil level
warning light
This light illuminates when the engine oil
level decreases to the lower limit.
If the engine low oil level warning light
illuminates while driving, park the vehicle
in a safe and level location, and then
check the engine oil level. When the
engine oil level is not within the normal
range, refill with engine oil. Refer to
“Engine oil ”F 11-8.

CAUTION
Trapping small animals in the cool-
ing fan and belts of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.
NOTE
Engine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
Starting and stopping the
engine (models without
push-button start system)
CAUTION
Do not operate the starter motor
continuously for more than 10 sec-
onds. If the engine fails to start after
operating the starter for 5 to 10
seconds, wait for 10 seconds or
more before trying again.
NOTE
It may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically
controlled throttle’s self-diagnosis
function. To overcome it, keep the
ignition switch in the “ON”position
for approximately 10 seconds before
starting the engine.
& Starting engine
! General precautions when starting
engine
WARNING
.Never start the engine from out-
side the vehicle (except when
using the remote engine start
system). It may result in an
accident.
. Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
. Do not start the engine near dry
foliage, paper, or other flam-
mable substances. The exhaust
pipe and exhaust emissions can
create a fire hazard at high
temperatures.
CAUTION
. If the engine is stopped during
driving, the catalyst may over-
heat and burn.

Driving tips/Trailer towing (Crosstrek models)
!Driving on grades
. Before going down a steep hill, slow
down and shift into lower gear (if neces-
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.
. When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating.
. When driving uphill in hot weather, pay
attention to the following indicators be-
cause the engine and transmission are
relatively prone to overheating.
: Coolant temperature high warning light
: AT OIL TEMP warning light (CVT models)
If the coolant temperature high warning
light and/or the AT OIL TEMP warning light
illuminates, immediately turn off the air
conditioner and stop the vehicle in the
nearest safe location. For further instruc-
tions and additional information, refer to
the following sections. –“If you park your vehicle in case of
an emergency ”F 9-2
–“ Engine overheating ”F 9-13
–“ Coolant temperature low indicator
light/Coolant temperature high warn-
ing light ”F 3-17 –“
AT OIL TEMP warning light (CVT
models) ”F 3-19
. For CVT models, avoid using the
accelerator pedal to stay stationary on
an uphill slope instead of using the
parking brake or foot brake. That may
cause the transmission fluid to overheat.
! Parking on a grade
Always block the wheels under both
vehicle and trailer when parking. Apply
the parking brake firmly. You should not
park on a hill or slope. 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
under both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then
apply the parking brake; slowly release
the regular brakes.
5. Shift into 1st or reverse gear (MT
models) or “P ” position (CVT models)
and shut off the engine.

Engine overheating
WARNING
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.
If the engine overheats, safely pull off the
road and stop the vehicle in a safe
location.
& If steam is coming from the
engine compartment
. Turn the ignition switch to the “LOCK”/
“OFF ”position and get everyone away
from the vehicle until it cools down.
. Contact an authorized SUBARU deal-
er.
& If no steam is coming from
the engine compartment
1. Keep the engine running at idling
speed. 2. Open the engine hood to ventilate the
engine compartment. Refer to
“Engine
hood ”F 11-5.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact an authorized
SUBARU dealer for repair.
3. After the coolant temperature high
warning light that has blinked or illumi-
nated in REDturns off, turn off the engine.
For details about the warning light, refer to
“Coolant temperature low indicator light/
Coolant temperature high warning light ”
F 3-17.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank. If the coolant level is below the
“LOW ”mark, add coolant up to the “FULL ”
mark.
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to “Engine coolant ”F 11-11.
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.
In case of emergency/Engine overheating9-13

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.
&
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.

When there is only a small amount of
washer fluid remaining, the windshield
washer fluid warning light will illuminate.
When this occurs, refill the washer fluid.
&Adding the windshield
washer fluid
CAUTION
Never use engine coolant as washer
fluid because it could cause paint
damage.
Remove the washer tank filler cap, then
add windshield washer fluid until it
reaches the “FULL”mark on the tank.
& Windshield washer fluid
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean
water.
In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid. SUBARU Windshield Washer Fluid
contains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the following
table.
Washer Fluid
Concentration Freezing
Temperature
30% 10.48F( −12 8C)
50% −48F( −20 8C)
100% −498F( −45 8C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside temperature, it may freeze and block the
nozzles.
CAUTION
.
Adjust the washer fluid concen-
tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.
