WARNING
.Do not remote start a vehicle in an
enclosed environment (e.g.
closed garage). Prolonged opera-
tion of a motor vehicle in an
enclosed environment can cause
a harmful build-up of Carbon
Monoxide. Carbon Monoxide is
harmful to your health. Exposure
to high levels of Carbon Monox-
ide can cause headaches, dizzi-
ness or in extreme cases uncon-
sciousness and/or death.
.Before performing any servicing
of the vehicle, temporarily place
the remote engine start system in
service mode to prevent the sys-
tem from unexpectedly starting
the engine.

WARNING
.Do not drive the vehicle with the
clutch disengaged (i.e., when the
clutch pedal is depressed) or with
the shift lever in the neutral
position. Engine braking has no
effect in either of these condi-
tions and the risk of an accident
is consequently increased.
.Do not engage the clutch (i.e.,
release the clutch pedal) sud-
denly when starting the vehicle.
By doing so the vehicle might
unexpectedly accelerate or the
transmission could malfunction.
CAUTION
Shift into reverse ONLY when the
vehicle has completely stopped. It
may cause damage to the transmis-
sion to try shifting into reverse when
the vehicle is moving.
&Shifting speeds!Recommended shifting speeds
The best compromise between fuel econ-
omy and vehicle performance during
normal driving is ensured by shifting up
at the speeds listed in the following table.
Shift up mph (km/h)
1st to 2nd 15 (24)
2nd to 3rd 25 (40)
3rd to 4th 40 (64)
4th to 5th 45 (72)
5th to 6th50 (80)
!Shift-up indicator (STI)The shift-up indicator appears to informthe driver about the upshift timing.
The shift-up indicator can be activated or
deactivated. For details, refer to“Gear
position indicator (MT models)/Shift-up
indicator (STI)”F3-34.
!Maximum allowable speeds
The following table shows the maximum
speeds that are possible with each differ-
ent gear. The tachometer’s needle will
enter the red area if these speeds are
exceeded.
With the exception of cases where sudden
acceleration is required, do not drive the
vehicle with the tachometer’s needle in-
side the red area. Failure to observe this
precaution can lead to excessive engine
wear and poor fuel economy.

WARNING
When shifting down a gear, ensure
that the vehicle is not travelling at a
speed exceeding the Maximum Al-
lowable Speed for the gear which is
about to be selected. Failure to
observe this precaution can lead to

engine over-revving and this in turn
can result in engine damage.
In addition, sudden application of
engine brakes when the vehicle is
travelling on a slippery surface can
lead to wheel locking; as a conse-
quence, control of the vehicle may
be lost and the risk of an accident
increased.NOTENever exceed the posted speed limit.&Driving tips
NOTEIf the accelerator and brake pedals are
depressed at the same time, driving
torque may be restrained. This is not a
malfunction.
Do not drive with your foot resting on the
clutch pedal and do not use the clutch to
hold your vehicle at a standstill on an
upgrade. Either of those actions may
cause clutch damage.
Do not drive with your hand resting on the
shift lever. This may cause wear on the
transmission components.
When it is necessary to reduce vehicle
speed due to slow traffic, turning corners,
or driving up steep hills, downshift to alower gear before the engine starts to
labor.
On steep downgrades, downshift the
transmission to 5th, 4th, 3rd or 2nd gear
as necessary; this helps to maintain a safe
speed and to extend brake pad life.
In this way, the engine provides a braking
effect. Remember, if you“ride”(over use)
the brakes while descending a hill, they
may overheat and not work properly.
The engine may, on rare occasions, knock
when the vehicle rapidly accelerates or
rapidly pulls away from a standstill. This
phenomenon is not an indication of a
problem in your vehicle.
Driver’s Control Center Dif-
ferential (C.DIFF/DCCD) (STI)
WARNING
Always use the utmost care when
driving. Being overconfident be-
cause you are driving a vehicle with
a driver’s control center differential
could easily lead to a serious acci-
dent.

CAUTION
.All the indicators will flash in the
event that the driver’scontrol
center differential has a malfunc-
tion. Have the vehicle inspected
by your SUBARU dealer.
.If a malfunction occurs in the
vehicle (for example, when the
rear differential oil temperature
warning light illuminates), all of
the indicators may disappear and
the setting value for the initial
limited slip differential (LSD) tor-
que of the driver’s control center
differential (C.DIFF/DCCD) may
be cancelled. However, it does
not indicate a malfunction of the
C.DIFF/DCCD itself.
The driver’s control center differential
allows you to freely change the degree of
limitation of the differential action (limited
slip differential (LSD) torque) of your
vehicle’s center differential.
By using the center differential control
switch, you can set an initial LSD torque
to match the road surface conditions,
driving conditions and your driving style.The driver’s control center differential has
the following modes.
.Auto mode: the system automatically
adjusts the initial LSD torque.
.Manual mode: you can change to the
desired mode manually by using the
center differential control switch.
NOTEIf you rapidly depress and release the
accelerator pedal while driving at low
speed, you may hear a knocking sound
from the vicinity of the center differen-
tial and rear differential. This sound
occurs because of the structure of the
center differential. It does not indicate a
problem.
&To change mode of driver’s
control center differentialPress the“AUTO-MANU”switch on the
center console to switch from auto mode to
manual mode or vice versa. When you
select the auto mode, the“AUTO”indicator
appears. When you select the manual
mode, the“AUTO”indicator disappears.

&Auto modeIn the auto mode, the system estimates the
driving and road conditions using signals
from the wheel speed sensor, throttle
position sensor, steering angle sensor
and brake switch, etc. According to the
result, it electronically and automatically
controls the degree of limitation of the
differential action (LSD torque) to optimize
the differential action of the center differ-
ential. When you turn the ignition switch
ON, the“AUTO”indicator on the combina-
tion meter appears.The auto mode has 3 modes as follows.
Mode Operation
AUTO [+] This mode emphasizes traction
control and strengthens the lim-
itation of differential action that
is suitable for driving on slippery
roads for vehicle stability.
AUTO This mode is suitable for most
driving situations.
AUTO [ ] This mode is suitable when you
seek quick response from the
steering wheel and smooth
driving.
!Mode setting method
In most situations, it is recommended that
the“AUTO”mode is selected.Push the control switch forward to select
the“AUTO [+]”mode. After setting themode,“AUTO [+]”appears.
Pull the control switch rearward to select
the“AUTO [ ]”mode. After setting the
mode,“AUTO [ ]”appears.
When the“AUTO [+]”mode is selected,
pull the control switch rearward to change
to the“AUTO”mode. When the“AUTO [ ]”
mode is set, push the control switch
forward to change to the“AUTO”mode.

this mode is selected, the“AUTO”indica-
tor disappears.!Center differential control switch
and indicator
The control switch is located beside the
parking brake lever. Push the control
switch forward or pull it rearward to change
the initial LSD torque.
The center differential indicator on the
combination meter gives six levels of
indication. The indicator and control switch
are linked; when operating the switch to
change the initial LSD torque, the indicator
changes accordingly.
Push the switch forward to increase the
initial LSD torque; when the“LOCK”
indicator appears, the initial LSD torque
setting is maximum. The center differential
will then be almost completely locked.
