2016 SUBARU WRX engine overheat

other than Sport Sharp (S#) mode is
selected.
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 another 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.
. While the engine is cool, you cannot
change to Sport Sharp (S#) mode. Limited slip differential (LSD)
(STI) The LSD provides optimum distribution of
power according to the difference in
revolutions between the right and left
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads or when high speed
driving.
CAUTION. Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
. If one tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely
affect the LSD.
. If you use a temporary spare tire
to replace a flat tire, be sure to
use the original temporary spare
tire stored in the vehicle. Using
other sizes will adversely affect
the LSD. Power steering & STI The vehicle is equipped with a hydraulic
power steering system. The power steer-
ing system operates only when the engine
is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.
CAUTIONDo not hold the steering wheel at the
fully locked position left or right for
more than 5 seconds. This may
damage the power steering pump.
NOTE Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is
normal. It does not indicate power
steering system trouble.Starting and operating/Limited slip differential (LSD) (STI)

Starting and operating/Power steering
& Except STI
Power steering warning light
The vehicle is equipped with an electric
power steering system. The power steer-
ing system operates only while the engine
is running. When the ignition switch is
turned to the “ ON ” position, the power
steering warning light on the combination
meter illuminates to inform the driver that
the warning system is functioning properly.
Then, if the engine started, the warning
light turns off to inform the driver that the
steering power assist is operational.
CAUTION
While the power steering warning
light is illuminated, there may be
more resistance when the steering wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.
NOTE If the steering wheel is operated in the
following ways, the power steering
control system may temporarily limit
the power assist in order to prevent the
system components, such as the con-
trol computer and drive motor, from
overheating.
. The steering wheel is operated fre-
quently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently turn-
ing the steering wheel during parallel
parking.
. The steering wheel remains in the
fully turned position for a long period
of time.
At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
force will be restored after the steering
wheel is not operated for a while and
the power steering control system has
an opportunity to cool down. However,
if the power steering is operated in a
non-standard way which causes power assist limitation to occur too fre-
quently, this may result in a malfunc-
tion of the power steering control
system.

Braking & Braking tips WARNINGNever rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.
! When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the vehicle
at a safe speed while lightly depressing
the brake pedal to heat up the brakes.
! Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To
help prevent this, shift into a lower gear to
get stronger engine braking.
! Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could cause a loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe place.
& Brake system ! Two separate circuits
Your vehicle has two separate circuit
brake systems. Each circuit works diag-
onally across the vehicle. If one circuit of
the brake system should fail, the other half
of the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop the
vehicle.
! Brake booster
The brake booster uses engine manifold
vacuum to assist braking force. Do not
turn off the engine while driving because
that will turn off the brake booster, result-
ing in poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, however, you
will have to depress the pedal much
harder than normal and the braking dis-
tance will increase. ! Brake assist system
WARNINGDo not be overconfident about the
brake assist. It is not a system that
brings more braking ability to the
vehicle beyond its braking capabil-
ity. Always use the utmost care
when driving regarding vehicle
speed and safe distance.
CAUTIONWhen you need to brake suddenly,
continue depressing the brake pedal
strongly to obtain the effect of the
brake assist.
Brake assist is a driver assistance system.
It assists the brake power when the driver
cannot depress the brake pedal strongly
and the brake power is insufficient.
Brake assist generates the brake power
according to the speed at which the driver
depresses the brake pedal.
NOTE When you depress the brake pedal
strongly or suddenly, the following
phenomena occur. However, even
though these occur, they do not indi- Starting and operating/Braking

Starting and operating/Parking your vehicle
! Hill Holder indicator light
When the Hill Holder function is activated,
the Hill Holder indicator light illuminates.
Refer to “ Hill Holder indicator light (models
with electronic parking brake system) ”
F 3-24.
! Emergency brake
CAUTION
Use the emergency brake only in
case of an emergency. If the emer-
gency brake is excessively used,
the brake parts will wear down
faster or the brake may not work
sufficiently due to brake overheat-
ing. NOTE . While using the emergency brake,
the electronic parking brake indicator
light and the indicator light on the
parking brake switch illuminate and a
chirp sounds.
. While using the emergency brake, a
sound may be heard from the engine
compartment. This is the operating
sound of the brake that is activated by
the Vehicle Dynamics Control system,
and does not indicate a malfunction.
If the foot brake has a malfunction, you
can stop the vehicle by pulling the parking
brake switch continuously.
While applying the emergency brake, the
electronic parking brake indicator light and
the indicator light on the parking brake
switch illuminate and a chirp sounds.
! Electronic parking brake system
warning
CAUTION
If the brake system warning light
turns on, the electronic parking
brake system may be malfunction-
ing. Immediately stop your vehicle
in the nearest safe location and
contact your SUBARU dealer.
If a malfunction occurs in the electronic parking brake system, the brake system
warning light turns on. Refer to “ Electronic
parking brake indicator light (models with
electronic parking brake system) ” F 3-23.
& Parking tips When parking your vehicle, always per-
form the following items.
. Apply the parking brake firmly.
. For MT models, put the shift lever in the
“ 1 ” (1st) for upgrade or “ R ” (Reverse) for a
downgrade.
. For CVT models, put the select lever in
the “ P ” (Park) position.
Never rely on the mechanical friction of
the transmission alone to hold the vehicle.
When parking on a hill, always turn the
steering wheel. When the vehicle is7-48

Engine overheating WARNINGNever 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 off the engine 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 11-9.
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 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 3-11.
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 11-18.
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 overheating
