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.

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

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

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 lbf·in (3.4 to 4.0 N·m, 0.35 to 0.41 kgf·m) of
torque (or tighten securely with the torx® wrench pro-
vided).

In case of emergency
13.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 lbf·ft (80
to 100 N·m, 8 to 10 kgf·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.
14.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-
age locations.
After placing the jack in its storage location, turn the
jackscrew clockwise by hand until it becomes too hard
to turn. Then, tighten it by an additional 1/4 – 1/3 of a
turn using a screwdriver or the jack handle. Unless the
jack is properly secured, it may rattle while the vehicleis moving.
Never place a tire or tire changing tools in the
passenger compartment after changing
wheels. In a sudden stop or collisions, loose
equipment could strike occupants and causeHS9014BA

Maintenance and service
Use only those wheels that are specified for
your vehicle. Wheels not meeting specifica-
tions could interfere with brake caliper opera-
tion and may cause the tires to rub against the
wheel well housing during turns. The resulting
loss of vehicle control could lead to an acci-
dent.
NOTE
When any of the wheels is removed and replaced
for tire rotation or to change a flat tire, alwayscheck 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.
Aluminum wheels
Aluminum wheels can be scratched and damaged
easily. Handle them carefully to maintain their appear-
ance, performance, and safety. y
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.y Never apply oil to the threaded parts, wheel nuts, or
tapered surface of the wheel.y Never let the wheel rub against sharp protrusions or
curbs. y Be sure to fit tire chains on uniformly and completely
around the tire, otherwise the chains may scratch the
wheel.y When wheel nuts, balance weights, or the center
cap is replaced, be sure to replace them with genuine
SUBARU parts designed for aluminum wheels.

left hand side of the vehicle. (Each tire must be
kept on its original side of the vehicle.) Replace
any damaged or unevenly worn tire at the time of
rotation. After tire rotation, adjust the tire pres-
sures and make sure the wheel nuts are correct-
ly tightened. A tightening torque specification
and a tightening sequence specification for the
wheel nuts can be found “Flat tires” in Chapter 9. „Vehicle load limit – how to determine
The load capacity of your vehicle is determined
by weight, not by available cargo space. The
load limit of your vehicle is shown on the vehicle
placard attached to the driver’s side B-pillar. Lo-
cate the statement “The combined weight of oc-
cupants and cargo should never exceed XXX kg
or XXX lbs” on your vehicle’s placard.
The vehicle placard also shows seating capacity
of your vehicle.
The total load capacity includes the total weight
of driver and all passengers and their belong-
ings, any cargo, any optional equipment such as
a trailer hitch, roof rack or bike carrier, etc., and
the tongue load of a trailer. Therefore cargo ca- pacity can be calculated by the following method.
Cargo capacity = Load limit – (total weight of oc-
cupants + total weight of optional equipment +
tongue load of a trailer (if applicable))
For towing capacity information and weight lim-
its, refer to “Trailer towing” in Chapter 8. T
Calculating total and load capacities vary-
ing seating configurations
Calculate the available load capacity as shown in
the following examples:
