2007 SUBARU IMPREZA WRX stop start

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.
See the “In case of emergency ”in

Outside temperature indica- tor
1) U.S.-spec. models
2) Canada-spec. models
The outside temperature indicator shows
the outside temperature in a range from 22 to 122 8F( 30 to 50 8C).
The indicator can give a false reading
under any of the following conditions: . When there is too much sun.
. During idling; while running at low
speeds in a traffic jam; when the engine
is restarted immediately following a shut- down. . When the actual outside temperature
falls outside the specified indicator range. REV indicator light and buz-
zer (WRX-STI)The REV alarm system issues a warning
using the REV indicator light (and a
buzzer if additionally selected) when the
engine speed reaches a level previously
set using the REV setting knob.
If you press the trip knob when the ignition
switch is in the
“LOCK ”position, the
outside temperature indicator will show
the engine speed that has already beenset. Instruments and controls

NOTE
Even if the REV alarm system is not set,
the REV indicator light will come on
whenever the engine speed enters thetachometer ’s red zone.
& Setting the alarm-level en-
gine speed
1. Turn the REV setting knob clockwise
or counterclockwise, then release it and
let it return to its initial position. The buzzer
will sound. The REV alarm system is now
ready to be set.
2. Turn the REV setting knob to select
the desired alarm-level engine speed.
At this time, the outside temperature
indicator will show the engine-speed setting. .
Counterclockwise ( ): Speed setting
changes downward by 100 rpm. . Clockwise (+): Speed setting
changes upward by 100 rpm.
The speed setting will stop changing if
it reaches 0 rpm or the maximum
engine speed.

The alarm-level engine speed can be set
(in 100 rpm steps) within the range from
2,000 rpm to 7,000 rpm.
The indicator shows the setting as follows:
Speed (rpm) Indication 00 0
2,000 20
2,100 21 ––
7,000 70
Approximately 3 seconds after you stop
turning the knob, the REV alarm system
will automatically enter its next setting
mode (step 3 below), in which you can
activate or deactivate the buzzer.
3. Activate or deactivate the buzzer as
desired using the REV setting knob. .Turn the knob clockwise (+) to
activate the buzzer. The indicator willshow “ON ”, and the buzzer will sound three times. With the buzzer activated,
engine-speed warnings are given by
both the REV indicator light and the
buzzer. .
Turn the knob counterclockwise ( )
to deactivate the buzzer. The indicator
will show “– –”, and the buzzer will not
sound. With the buzzer deactivated,
engine-speed warnings are given only
by the REV indicator light.
Approximately 3 seconds after you stop
turning the knob, the buzzer will sound
once to indicate the end of the setting
procedure. The indicator will return to
showing the outside temperature.
Also, the tachometer needle will return to approximately “0 ”.
NOTE . The REV alarm system does not
operate while settings are being en- tered.. The speed-setting mode terminates
if 0 rpm is selected.. The speed-setting mode is canceled
if the ignition switch is turned to OFF or
the vehicle starts moving before the
setting procedure is finished.. Speed setting is impossible when
the vehicle is moving.. The set engine speed may differ

fuel quantity of approximately 4.0 US
gal (15 liters, 3.3 Imp gal).
CAUTION
(Turbo model only)
Promptly put fuel in the tank when-
ever the low fuel warning light
comes on. Engine misfires as a
result of an empty tank could cause
damage to the engine.
& 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.

&CHECK ENGINE warn-
ing light/Malfunction in-
dicator lamp
CAUTION
If the CHECK ENGINE light comes
on while you are driving, have your
vehicle checked/repaired by your
SUBARU dealer as soon as possi-
ble. Continued vehicle operation
without having the emission control
system checked and repaired as
necessary could cause serious da-
mage, which may not be covered by
your vehicle ’s warranty.
If this light comes on steadily or blinks
while the engine is running, it may indicate
that there is a problem or potential
problem somewhere in the emission con-
trol system. ! If the light comes on steadily:
If the light comes on steadily while driving
or does not go out after the engine starts,
an emission control system malfunction
has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immedi-
ately. NOTE
This light also comes on 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 lamp coming on
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 go out, 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 thefollowing. . Reduce vehicle speed.
. Avoid hard acceleration.
. Avoid steep uphill grades.
. Reduce the amount of cargo, if possi-
ble.. Stop towing a trailer as soon as
possible. The CHECK ENGINE warning light may
stop blinking and come on steadily after
several driving trips. You should have your
vehicle checked by an authorized
SUBARU dealer immediately. &
Charge warning light
If this light comes on when the engine is
running, it may indicate that the charging
system is not working properly.
If the light comes on while driving or does
not go out 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 on, contact
your nearest SUBARU dealer immedi-
ately. &Oil pressure warning light
If this light comes on 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 comes on while driving or does
not go out 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 remains on,

contact your nearest SUBARU dealer
immediately.
CAUTION
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
& AT OIL TEMPerature
warning light (AT vehi- cles)
The AT oil temperature warning light
comes on when the ignition switch is
turned to the “ON ”position and goes out
after the engine has started.
If this light comes on when the engine is
running, it may indicate that the automatic
transmission fluid temperature is too hot.
If the light comes on while driving, it is
unnecessary to stop the vehicle, but avoid
driving up steep grades or in stop and go
traffic. ! Automatic transmission control
system warning
If the light flashes after the engine starts, it
may indicate that the automatic transmis-
sion control system is not working prop-
erly. Contact your nearest SUBARU deal- er for service immediately.
& Rear differential oil
temperature warning
light (WRX-STI)
CAUTION
Reduce vehicle speed and park the
vehicle in a safe place as soon as
possible if the R.DIFF TEMP light
comes on. Continued driving with
this light on can damage the rear
differential and other parts of thepowertrain.
If this light comes on when the engine is
running, it may indicate that the rear
differential oil temperature is too hot.
At this time, the driver ’s control center
differential will automatically cancel the
current torque-distribution ratio setting and
adopts its minimum ratio.
If the light comes on while driving, reduce
vehicle speed and stop the vehicle at the
nearest safe place.
Park the vehicle for several minutes. After
the light goes out, you can start driving.
If the light does not go out, contact the
nearest SUBARU dealer for service. NOTE .
If the tire pressures are not correct
and/or the tires are not all the same
size and brand, the rear differential will
be heavily loaded when the vehicle is
driven, resulting in an abnormally high
oil temperature.. The rear differential oil will deterio-
rate if its temperature increases en-
ough for the rear differential oil tem-
perature warning light to come on. It is
advisable to have the rear differential
oil replaced as soon as possible. & ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON ”
position and goes out after approximately
2 seconds.
This is an indication that the ABS system
is working properly.
CAUTION
If the warning light behaves as
follows, the ABS system may not
work properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally. Instruments and controls

.The warning light does not come
on when the ignition switch is
turned to the “ON ”position.
. The warning light comes on when
the ignition switch is turned tothe “ON ”position, but it does not
go out even when the vehicle
speed exceeds approximately 8
mph (12 km/h).
. The warning light comes on dur-
ing driving.
If any of these conditions occur,
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer.
With a vehicle equipped with an EBD
system, the ABS warning light comes on
together with the brake system warning
light if the EBD system becomes faulty.
For further details of the EBD system fault
warning, refer to “Brake system warning
light ”.
NOTE
If the warning light behavior is as
described in the following, the ABS
system may be considered normal. . The warning light comes on right
after the engine is started but goes out
immediately, remaining off.. The warning light remains on after the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h)..
The warning light comes on during
driving, but it goes out immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may come
on. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out. & Brake system warning light
WARNING
. Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, we recom-
mend that you have the brakes
inspected by a SUBARU dealer
immediately.
. If at all in doubt about whether
the brakes are operating prop-
erly, do not drive the vehicle.
Have your vehicle towed to the
nearest SUBARU dealer for re- pair.
This light has the following three functions: ! Parking brake warning
The light comes on with the parking brake
applied while the ignition switch is in the“ ON ”position. It goes out when the
parking brake is fully released. ! Brake fluid level warning
This light comes on when the brake fluid
level has dropped to near the “MIN ”level
of the brake fluid reservoir with the ignition
switch in the “ON ”position and with the
parking brake fully released.
If the brake system warning light should
come on while driving (with the parking
brake fully released and with the ignition
switch positioned in “ON ”), it could be an
indication of leaking of brake fluid or worn
brake pads. If this occurs, immediately
stop the vehicle at the nearest safe place
and check the brake fluid level. If the fluid
level is below the “MIN ”mark in the
reservoir, do not drive the vehicle. Have
the vehicle towed to the nearest SUBARU
dealer for repair. ! Electronic Brake Force Distribution
(EBD) system warning
The brake system warning light also

illuminates if a malfunction occurs in the
EBD system. In that event, it comes on
together with the ABS warning light.
The EBD system may be malfunctioning if
the brake system warning light and ABS
warning light illuminate simultaneously
during driving.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are
applied harder than usual and the vehi-cle’s motion may therefore become some-
what harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps:
1. Stop the vehicle in the nearest safe,
flat place.
2. Shut down the engine, apply the
parking brake and then restart it.
3. Release the parking brake. If both
warning lights go out, the EBD system
may be faulty. Drive carefully to the
nearest SUBARU dealer and have the
system inspected.
4. If both warning lights come on again
and stay illuminated after the engine has
been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level. 5. If the brake fluid level is not below the“
MIN ”mark, the EBD system may be
faulty. Drive carefully to the nearest
SUBARU dealer and have the systeminspected.
6. If the brake fluid level is below the “ MIN ”mark, DO NOT drive the vehicle.
Instead, have the vehicle towed to the
nearest SUBARU dealer for repair.
& Door open warning light
The door open warning light comes on if
any door or the rear gate is not fullyclosed.
Always make sure this light is out before
you start to drive. &All-Wheel Drive warn-
ing light (AWD AT vehicles –if equipped)
The All-Wheel Drive warning light comes
on when the ignition switch is turned to the“ON ”position and goes out after the
engine has started.
This light comes on when All-Wheel Drive
is disengaged and the drive mechanism is
switched to Front Wheel Drive for main-
tenance or similar purposes (Non-turbo vehicles). It flashes if the vehicle is driven with tires
of differing diameters fitted on the wheels
or with an excessively low air pressure in
any of the tires.
CAUTION
Continuing to drive with the AWD
warning light flashing can damage
the powertrain. If the AWD warning
light starts to flash, promptly park in
a safe place and check whether the
tires have differing diameters and
whether any of the tires has an
excessively low inflation pressure.
& Intercooler water spray
warning light (WRX-STI)
This light comes on when the water level
in the intercooler water spray tank falls to
the lower limit (approximately 0.4 US qt,
0.4 liter, 0.4 Imp qt). Instruments and controls
3-19
