Do not operate the engine with the oil pressure
warning light on. This may cause serious en-
gine damage.
! AT OIL TEMPerature warning
light (for AT vehicles)
If this light comes on when the engine is running, it
may indicate that the automatic transmission fluid tem-
perature 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 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 neares
SUBARU dealer for service.

!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.

Starting and operating
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

tion meter give six levels of indication. The indicator
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.
"
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." 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

3) Front crossbar
4) 100LBS load label
5) Lower clamp
6) Roof rail end support

1. Before placing the crossbar on the roof rails, make
sure that the T-30 torx® head screw is removed from
the top of each crossbar end support.
2. Rotate the lower clamp on the bottom of each end
support downward approximately 90 °.
3. With the front direction arrow label on the top right
side of the crossbar pointing toward the front of the ve-
hicle, carefully place the crossbar across the top of the
vehicle so that the crossbar end supports rest on the
top of the roof rails approximately 3 inches (76 mm)
rearward from the seam (joint) between the front roof
rail support and the roof rail.
4. Rotate (raise) the lower clamp up to the bottom of
the roof rail and loosely tighten the T-30 torx® head
screw with the torx® wrench provided, through the top
of the end support and into the threaded insert in the
lower clamp on each end of the crossbar.NOTE
It may be necessary to squeeze the lower clamp
and the end support together to compress the
pads and gain a better alignment of the pieces
while trying to start the screw. Use care not to
crossthread the screw in the insert.
5. Adjust the alignment of the crossbar on the roof
rails, and if available, use a T-30 torx® bit and torque
wrench and tighten the T-30 torx® head screws to 30
to 35 inch lbs. (3.4 to 4.0 N-m, 0.35 to 0.41 kg-m) of
torque (or tighten securely with the torx® wrench pro-
vided).

surface of the wheel and hub with a cloth.
12.Put on the spare tire. Replace the wheel nuts.
Tighten them by hand.
Do not use oil or grease on the wheel studs or
nuts when the spare tire is installed. This could
cause the nuts to become loose and lead to an
accident.
13.Turn the jack handle counterclockwise to lower the
vehicle. 14.Use the wheel nut wrench to securely tighten the
wheel nuts to the specified torque, following the tight-
ening order in the illustration.
The torque for tightening the nuts is 58 to 72 ft-lb (80
to 100 N-m, 8 to 10 kg-m). This torque is equivalent to
applying about 88 to 110 lbs (40 to 50 kg) at the top of
the wheel nut wrench. Never use your foot on the
wheel nut wrench or a pipe extension on the wrench
because you may exceed the specified torque. Have
the wheel nut torque checked at the nearest automo-
tive service facility.
15.Store the flat tire in the spare tire compartment.
Put the spacer and tighten the attaching bolt firmly.
Also store the jack and wheel nut wrench in their stor-

! Removing the wheel cover
Insert the wheel cover remover into the notch provid-
ed, and pry the wheel cover off. !
Installing the wheel cover
Align the valve with the valve hole in the cover, then fit
the cover on the wheel by tapping your hand evenly
around the circumference of the cover.
NOTE
When any of the wheels is removed and replaced
for tire rotation or to change a flat tire, always
check the tightness of the wheel nuts after driving
approximately 600 miles (1,000 km). If any nut is
loose, tighten it to the specified torque.UG9506BA

Aluminum wheels (If equipped)
Aluminum wheels can be scratched and damaged
easily. Handle them carefully to maintain their appear-
ance, performance, and safety. "When any of the wheels is removed and replaced
for tire rotation or to change a flat, always check the
tightness of the wheel nuts after driving approximately
600 miles (1,000 km). If any nut is loose, tighten it to
the specified torque. " Never apply oil to the threaded parts, wheel nuts, or
tapered surface of the wheel. " Never let the wheel rub against sharp protrusions or
curbs." Be sure to fit tire chains on uniformly and completely
around the tire, otherwise the chains may scratch the
wheel. " When wheel nuts, balance weights, or the center
cap is replaced, be sure to replace them with genuine
SUBARU parts designed for aluminum wheels.Intercooler water spray
Add water to the intercooler water spray tank when the
intercooler water spray warning light in the combina-
tion meter comes on. The warning light comes on
when the water in the tank has decreased to approxi-
mately 0.4 liters (0.4 US qt, 0.4 Imp qt).
