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. TAutomatic transmission control system warn- ing
If the light flashes after the engine starts, it may indi-cate that the automatic transmission control system is
not working properly. Contact your nearest SUBARU
dealer for service immediately. „ Rear differential oil temperature
warning light (WRX-STi)
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 the powertrain.
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 ra-
tio 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 y
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 tem-
perature.y The rear differential oil will deteriorate if its tem-
perature increases enough for the rear differential
oil temperature warning light to come on. It is ad-
visable 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
about two seconds.
This is an indication that the ABS system is working
properly.

„
Driver’s control center differen-
tial auto indicator light (WRX-STi)
This light functions while the ignition switch is ON.
When on, it indicates that the driver’s control center
differential is set to AUTO mode. It goes off when the
driver’s control center differential’s manual mode
switch is pressed. For details, refer to Chapter 7, “Driv-
er’s Control Center Differential (DCCD) (WRX-STi)”. „ Driver’s control center differential indi-
cator lights (WRX-STi)
These indicator lights show the current differential-ac-
tion limiting factor (torque-distribution ratio between the front and rear wheels) of the center differential.
The bottom indicator light “ ” flashes in the event of
failure of the driver’s control center differential. For de-
tails, refer to Chapter 7, “Driver’s Control Center Dif-
ferential (DCCD) (WRX-STi)”. „
Headlight indicator light (WRX-
STi)
This light comes on when the headlight switch is
placed in the “ ” or “ ” position. „ REV indicator light (WRX-STi)
This light comes on when the engine speed reaches a
level set by the user and when the tachometer needle
enters the red zone.

Driver’s Control Center Differential
(DCCD) (WRX-STi)
Always use the utmost care when driving. Be-
ing overconfident because you are driving a ve-
hicle with a driver’s control center differential
could easily lead to a serious accident.
In the event of failure of the driver’s control
center differential, the “ ” indicator light will
flash and the auto mode and manual mode will
both stop functioning. Have the vehicle in-
spected by your Subaru dealer.
„ Auto mode
This system automatically adjusts the differential-ac-
tion limiting factor (torque-distribution ratio between
the front and rear wheels) of the center differential to

suit driving and road-surface conditions. When the ig-
nition switch is turned ON, the “AUTO” indicator light
in the combination meter comes on. The system can
be switched to a manual mode. „Manual mode
The manual mode allows the driver to set the differen-
tial-action limiting factor of the center differential as
desired to suit driving and road-surface conditions.
When this mode is selected, the “AUTO” indicator light
in the combination meter goes off. T Manual switch
Press the “DCCD-MANU” switch on the center con- sole to switch from auto mode to manual mode. The
“AUTO” indicator light in the combination meter will go
off. Press the switch again to go back to auto mode.
The “AUTO” indicator light in the combination meter
will come on. T
Center differential control dial and indicator
light
The control dial is located beside the parking-brake le-
ver. By turning the control dial forward and rearward,
it is possible to change the differential-action limiting
factor of the center differential.
The center-differential indicator lights in the combina-
tion meter give six levels of indication. The indicator

Starting and operating
lights and control dial are linked; when the dial is
turned to change the differential-action limiting factor
(front/rear torque-distribution ratio), the illumination
position of the indicator lights change accordingly.
Turn the dial forward to increase the differential-action
limiting factor. If the white line on the dial reaches the
frontmost position, the center differential will be almost
completely locked and the “LOCK” indicator light will come on.
Turn the dial rearward to reduce the differential-action
limiting factor. If the white line on the dial reaches the
rearmost position, the factor will be minimal and the
“ ” indicator light will come on.
y
Do not turn the control dial when a wheel slip-
page occurs. Wait until the wheelspin has been
brought under control or select the auto mode. y When the vehicle has been fitted with a tem-
porary spare tire or is to be towed, turn the con-
trol dial fully rearward (to minimize the differen-
tial-action limiting factor) or select the auto

mode.
NOTE yIf the differential-limiting factor is large during
cornering maneuvers, a small speed difference
between the front and rear wheels may cause tight
corner braking (a phenomenon accompanied by
vibration and noise). This phenomenon does not
indicate a problem. It will disappear if the differen-
tial-action limiting factor is reduced.y Use the center-differential indicator light only as
a rough indication of the differential-action limit-
ing factor.y If you rapidly depress and release the accelera-
tor pedal while driving at low speed, you may hear
a knocking sound from the vicinity of the center
differential and rear differential. This sound oc-
curs because of the structure of the center differ-
ential. It does not indicate a problem. „ Temporary release
When the driver stop the vehicle and pulls the parking-
brake lever after manually setting the differential-ac-
tion limiting factor, the factor is temporarily minimized.
The indicator in the combination meter continues to
show the driver’s selected differential-action limiting factor. When the driver releases the parking-brake le-
ver, the factor set by the driver is restored.

Starting and operating
4. Insert the screwdriver into the hole.
5. Push down on the screwdriver and move the selec-
tor lever from the “P” to the “N” position.
6. Remove the screwdriver from the hole. Depress
the brake pedal and start the engine.
Take your vehicle to the nearest SUBARU dealer im-
mediately to have the system repaired.
Limited slip differential (LSD) (if
equipped)
The LSD provides optimum distribution of power ac-
cording to the difference in revolutions between the
right and left wheels that may be caused by certain
driving conditions, thereby improving driving stability
on snow-covered, muddy or other slippery roads or
when high speed driving.
NOTE (WRX-STi)
The rear differential may emit a knocking sound
when the vehicle is driven slowly with the steering wheel turned fully to either side. This sound oc-
curs because of the design of the mechanical LSD.
It does not indicate a problem.
y
Never start the engine while a tire on one side
is jacked up, as the vehicle may move. y If one tire is spinning in mud, avoid continued
spinning at high speed as this could adversely
affect the LSD. y 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 siz-
