& System maintenance
! Changing the batteries
CAUTION
. Do not let dust, oil or water get on
or in the remote engine start
transmitter when replacing the
battery.
. Be careful not to damage the
printed circuit board in the re-
mote engine start transmitter
when replacing the battery.
. Be careful not to allow children to
touch the battery and any re-
moved parts; children could
swallow them.
. There is a danger of explosion if

an incorrect replacement battery
is used. Replace only with the
same or equivalent type of bat-
tery.
. Batteries should not be exposed
to excessive heat such as sun-
shine, fire or the like.
The two 3-volt lithium batteries (modelCR-1220 ) supplied in your remote engine
start transmitter should last approximately
3 years, depending on usage. When the
batteries begin to weaken, you will notice
a decrease in range (distance from the
vehicle that your remote engine start
system operates). Follow the instructions
below to change the remote engine start
transmitter batteries.
1. Carefully pry the remote engine start
transmitter halves apart using a small flat-
head screwdriver.2. Remove the circuit board from the
bottom half of the case and slide the white
plastic battery holder out from under the
battery tab releasing the batteries. Re-
move the old batteries and replace with
new ones. Be sure to observe the (+) sign
on the old batteries before removing them
to ensure that the new batteries are
inserted properly (battery “+ ” should be
pointed away from the transmitter circuit
board on both batteries).
3. Carefully snap the case halves back
together, then test the remote engine startsystem.

–6
speeds (STI)
The manual transmission is a fully syn-
chromeshed, 6-forward-speed and 1-re-
verse-speed transmission.
The shift pattern is shown on the shift
lever knob.
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.

&Selecting reverse gear
1) Slider
You must raise the slider and hold it in that
position before you can move the shift
lever to the “R ”position.
To change gears, fully depress the clutch
pedal, move the shift lever, and gradually
let up on the clutch.
If it is difficult to shift into gear, put the
transmission in neutral, release the clutch
pedal momentarily, and then try again.
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 6th 50 (80)
! 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 areexceeded.
With the exception of cases where sudden
acceleration is required, the vehicle
should not be driven with the tachometer ’s
needle inside the red area. Failure to
observe this precaution can lead to
excessive engine wear and poor fuel economy.
Gear mph (km/h)1st 31 (50)
2nd 50 (81) 3rd 74 (119)
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 accidentincreased.
NOTE
Never exceed posted speed limits.

& Driving tips
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 a
lower 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 does not indicate a malfunc-tion. Manual transmission

lever knob. When shifting from 5th gear to
reverse gear, first return the shift lever to
the neutral position then shift into reverse
gear.
To change gears, fully depress the clutch
pedal, move the shift lever, and gradually
let up on the clutch pedal.
If it is difficult to shift into gear, put the
transmission in neutral, release the clutch
pedal momentarily, and then try again.

7-22Starting and operating/SI–DRIVE (STI)
SI-DRIVE (STI)
SI-DRIVE (SUBARU Intelligent Drive)
works to maximize engine performance,
control and efficiency.
This system consists of three modes:
Intelligent (I), Sport (S), and Sport Sharp
(S#). By adjusting the SI-DRIVE selector,
the character of the power unit changes. & Intelligent (I) mode
! For smooth, efficient performance driving
The Intelligent (I) mode provides well-
balanced performance with greater fuel
efficiency and smooth driveability without
stress. Power delivery is moderate during
acceleration for maximum fuel efficiency. This is ideal for around-town driving and
situations that do not require full power
output. It provides better control in difficult
driving conditions, such as slippery roads
or loose surfaces, due to gentler throttleresponse.
When Intelligent (I) mode is selected, a
shift-up indicator
“”on the combination
meter will blink to signal the best time to
shift gears for maximum fuel efficiency. &
Sport (S) mode
! For all-around performance driving
The Sport (S) mode provides the engine
power desired by those who want to make
the driving experience their own personaladventure.
The linear acceleration characteristic of
this versatile mode is ideal for normal
driving use.

&Sport Sharp (S#) mode
! For maximum performance driving
For sports-minded drivers, the Sport
Sharp (S#) mode offers an exhilarating
level of engine performance and control.
The throttle becomes more responsive
regardless of the engine speed. Delivering
maximum driving enjoyment, this mode is
ideal for tackling twisting roads and for
merging or overtaking other vehicles on
the freeway with confidence. &
SI-DRIVE selector
When you rotate the SI-DRIVE selector to
the left, the current SI-DRIVE mode
changes to Sport (S) mode. When you
rotate it to the right, the mode changes to
Sport Sharp (S#) mode, and when you
push it, the mode changes to Intelligent (I)
mode. After performing this operation, the
switch returns to its original location.
NOTE . The next time you turn on the
engine, after you turned off the engine
in the Sport Sharp (S#) mode, the SI-
DRIVE mode changes to the Sport (S)mode.. The next time you turn on the
engine, after you turned off the engine
in the Sport (S) mode or Intelligent (I)
mode, the SI-DRIVE mode will stay in the same mode as when the engine
was turned off..
While the engine is running, if the
CHECK ENGINE warning light/malfunc-
tion indicator light illuminates, the SI-
DRIVE mode changes to the Sport (S)
mode. In this case, it is not possible to
change to the Sport Sharp (S#) mode or
Intelligent (I) mode.. If there is a possibility that the
engine could overheat because of a
temperature increase of the engine
coolant, it is not possible to change to
the Sport Sharp (S#) mode. While the
vehicle is in the Sport Sharp (S#) mode,
it changes to the Sport (S) mode when
the engine coolant temperature in- creases.. If any of the SI-DRIVE indicators
blink, the SI-DRIVE system may be
malfunctioning. Contact your SUBARU
dealer.
Starting and operating/SI –DRIVE (STI)7-23

7-24Starting and operating/Limited slip differential (LSD) (STI)
Limited slip differential (LSD) (STI)
The LSD provides optimum distribution of
power according to the difference in
revolutions between the right and left
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads or when high speeddriving.
CAUTION
. Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
. If one tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely
affect the LSD.
. 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 sizes will adversely affect
the LSD. Power steering
The power steering system operates only
when the engine is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.
CAUTION
Do not hold the steering wheel at the
fully locked position left or right for
more than 5 seconds. This may
damage the power steering pump.
NOTE
Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is
normal. It does not indicate power
steering system trouble. Braking &
Braking tips
WARNING
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.
! When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the vehicle
at a safe speed while lightly depressing
the brake pedal to heat up the brakes. ! Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To
help prevent this, shift into a lower gear to
get stronger engine braking. ! Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could cause
