2014 SUBARU IMPREZA WRX coolant level

3-10Instruments and controls/REV indicator light and buzzer (STI)
&Temperature gauge
1) Normal operating range
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON ”position.
The coolant temperature will vary in
accordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range
and high revving operation when the
engine is not warmed up enough should
be avoided.
CAUTION
If the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.
Refer to “Engine overheating ”F9-
12. REV indicator light and buz-
zer (STI)
The REV alarm system has the following functions. .
When the engine speed reaches the
level that was previously set, the REV
indicator light illuminates to inform you. At
this time, a buzzer also sounds if the
buzzer setting is activated. . Whenever the engine speed enters the
red zone of the tachometer, the REV
indicator light flashes.
If you press the trip knob, the odometer/
trip meter will show the engine speed that
has already been set.

7-8Starting and operating/Preparing to drive
.A vehiclefails the OBDII inspection if
the “CHECK ENGINE ”warning light is not
properly operating (light is illuminated or is
not working due to a burned out bulb) or
there is one or more diagnostic trouble
codes stored in the vehicle ’s computer.
. A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBDII system readiness monitors “NOT
READY ”is greater than one. If the
vehicle ’s battery has been recently re-
placed or disconnected, the OBDII system
inspection may indicate that the vehicle is
not ready for the emission test. Under this
condition, the vehicle driver should be
instructed to drive his/her vehicle for a few
days to reset the readiness monitors and
return for an emission re-inspection. . Owners of rejected or failing vehicles
should contact their SUBARU Dealer for service.
Some states still use dynamometers in
their emission inspection program. A
dynamometer is a treadmill or roller-like
testing device that allows your vehicle ’s
wheels to turn while the vehicle remains in
one place. Prior to your vehicle being put
on a dynamometer, tell your emission
inspector
not to place your SUBARU
AWD vehicle on a two-wheel dynam-
ometer. Otherwise, serious transmis-
sion damage will result. The U.S. Environmental Protection
Agency (EPA) and states using two-wheel
dynamometers in their emission testing
program have EXEMPTED SUBARU
AWD vehicles from the portion of the
testing program that involves a two-wheel
dynamometer. There are some states that
use four-wheel dynamometers in their
testing program. When properly used, this
equipment should not damage a SUBARU
AWD vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
Preparing to drive
You should perform the following checks
and adjustments every day before you
start driving.
1. Check that all windows, mirrors, and
lights are clean and unobstructed.
2. Check the appearance and condition
of the tires. Also check tires for properinflation.
3. Look under the vehicle for any sign of leaks.
4. Check that the hood, trunk (4-door)
and rear gate (5-door) are fully closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside
and outside mirrors.
7. Fasten your seatbelt. Check that your
passengers have fastened their seatbelts.
8. Check the operation of the warning
and indicator lights when the ignition
switch is turned to the
“ON ”position.
9. Check the gauges, indicator and warn-
ing lights after 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.

&Sport Sharp (S#) mode
! For maximum performance driving
For sports-minded drivers, the Sport
Sharp (S#) mode offers an exhilarating
level of engine performance and control.
The throttle becomes more responsive
regardless of the engine speed. Delivering
maximum driving enjoyment, this mode is
ideal for tackling twisting roads and for
merging or overtaking other vehicles on
the freeway with confidence. &
SI-DRIVE selector
When you rotate the SI-DRIVE selector to
the left, the current SI-DRIVE mode
changes to Sport (S) mode. When you
rotate it to the right, the mode changes to
Sport Sharp (S#) mode, and when you
push it, the mode changes to Intelligent (I)
mode. After performing this operation, the
switch returns to its original location.
NOTE . The next time you turn on the
engine, after you turned off the engine
in the Sport Sharp (S#) mode, the SI-
DRIVE mode changes to the Sport (S)mode.. The next time you turn on the
engine, after you turned off the engine
in the Sport (S) mode or Intelligent (I)
mode, the SI-DRIVE mode will stay in the same mode as when the engine
was turned off..
While the engine is running, if the
CHECK ENGINE warning light/malfunc-
tion indicator light illuminates, the SI-
DRIVE mode changes to the Sport (S)
mode. In this case, it is not possible to
change to the Sport Sharp (S#) mode or
Intelligent (I) mode.. If there is a possibility that the
engine could overheat because of a
temperature increase of the engine
coolant, it is not possible to change to
the Sport Sharp (S#) mode. While the
vehicle is in the Sport Sharp (S#) mode,
it changes to the Sport (S) mode when
the engine coolant temperature in- creases.. If any of the SI-DRIVE indicators
blink, the SI-DRIVE system may be
malfunctioning. Contact your SUBARU
dealer.

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 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
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to “Engine coolant ”F 11-12.
1. Keep the engine running at idlingspeed. 2. Open the 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 your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If temperature gauge stays in the over-
heated zone, turn off the engine. Refer to“ Temperature gauge ”F 3-10.
4. After the engine has fully cooled down,
check the coolant level in the reservetank.
If the coolant level is below the “LOW ”
mark, add coolant up to the “FULL ”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. Towing
If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following
procedures for safety.
WARNING
Never tow AWD models with the
front wheels raised off the ground
while the rear wheels are on the
ground, or with the rear wheels
raised off the ground while the front
wheels are on the ground. This will
cause the vehicle to spin away due
to the operation or deterioration of
the center differential.

! 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 isremoved.
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
as required.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.
