light remains on, contact your nearest SUBARU deal-
er immediately. „Oil pressure warning light
If this light comes on when the engine is running, it
may indicate that the engine oil pressure is low and the
lubricating system is not working properly.
If the light comes on while driving or does not go out
after the engine starts, stop the engine at the first safe
opportunity and check the engine oil level. If the oil lev-
el is low, add oil immediately. If the engine oil is at the
proper level but the light remains on, contact your
nearest SUBARU dealer immediately.
Do not operate the engine with the oil pressure
warning light on. This may cause serious en-
gine damage.
„ AT OIL TEMPerature warning
light (AT vehicles)
The AT oil temperature warning light comes on when
the ignition switch is turned to the “ON” position and
goes out after about two seconds. 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. T
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. „ 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.
If the warning light behaves as follows, the ABS
system may not work properly.
When the warning light is on, the ABS function
shuts down; however, the conventional brake

Automatic transmission
The automatic transmission is electronically controlled
and provides 4 forward speeds and 1 reverse speed.
NOTE yWhen the engine coolant temperature is still
low, your vehicle’s automatic transmission will
up-shift at higher engine speeds than when the
coolant temperature is sufficiently high in order to
shorten the warm-up time and improve driveabili-
ty. The gearshift timing will automatically shift to
the normal timing after the engine has warmed up. y Immediately after ATF (automatic transmission
fluid) is replaced, you may feel that the automatic
transmission operation is somewhat unusual.
This results from erasure or invalidation of data
the on-board computer has collected and stored in memory to allow the transmission to shift at the
most appropriate times for the current condition
of your vehicle. Optimized shifting will be restored
as the vehicle continues to be driven for a while.
Do not shift from the “P” or “N” position into
the “D”, “3”, “2”, “1” or “R” position while de-
pressing the accelerator pedal. This may cause
the vehicle to jump forward or backward.
y Shift into the “P” or “R” position only after
the vehicle is completely stopped. Shifting
while the vehicle is moving may cause damage
to the transmission. y Do not race the engine for more than five sec-
onds in any position except the “N” or “P” po-
sition when the brake is set or the tires are on
blocks. This may cause the automatic transmis-
sion fluid to overheat.y Avoid shifting from one of the forward driving
positions into the “R” position or vice versa un-
til the vehicle has completely stopped. Such
shifting may cause damage to the transmis-
sion.

Starting and operating
V
While climbing a grade
When driving up hill, undesired upshift to 4th gear is
prevented from taking place when the accelerator
pedal is released. This minimizes the chances of sub-
sequent downshifting to a lower gear when accelerat-
ing again. This prevents repeated upshifting and
downshifting resulting in a smoother operation of the
vehicle.
NOTE
The transmission may downshift to 2nd or 1st
gear, depending on the way the accelerator pedal
is pressed to accelerate the vehicle again. V While going down a hill
When descending a steep hill, depressing the brake
pedal will cause the transmission to downshift to 3rd
gear, thus applying engine braking. Reacceleration for
a short time will cause the transmission to upshift nor-
mally.
NOTE
In some cases, depressing the brake pedal on a
downhill grade does not result in an automatic
downshift to 3rd gear. This can happen when the
automatic transmission fluid temperature is very
low, for example, during driving shortly after the
vehicle has been parked for an extended period of time. When the ATF temperature has risen to a cer-
tain level, automatic downshift normally takes
place. In the meantime, downshift manually for en-
gine braking as required.
Also, downshifting when braking downhill will not
occur at speeds above approximately 48 mph (78
km/h). T
3 (Third)
This position is for using engine braking when going
down a hill or for climbing a grade.
The transmission automatically shifts into a suitable
gear from 1st to 3rd according to the vehicle speed
and the acceleration you require.
When more acceleration is required in this position,
press the accelerator pedal fully to the floor and hold
that position. The transmission will automatically
downshift to 2nd or 1st gear. When you release the
pedal, the transmission will return to the original gearposition. T 2 (Second)
This position is for using engine braking when going
down a hill or for climbing a steep grade.
In this position, the transmission holds in the 2nd gear.
Use this position when starting off from a standstill on
slippery road surfaces such as mud or snow. It will en-

performed immediately by the nearest SUBARU deal- er. TDriving on grades
y Before going down a steep hill, slow down and shift
into lower gear (if necessary, use 1st gear) in order to
utilize the engine braking effect and prevent overheat-
ing of your vehicle’s brakes. Do not make sudden
downshifts. y When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating. y When driving uphill in hot weather, pay attention to
the water temperature gauge pointer (for all vehicles)
and AT OIL TEMP warning light (for AT vehicles) since
the engine and transmission are relatively prone to
overheating under these conditions. If the water tem-
perature gauge pointer approaches the OVERHEAT
zone or the AT OIL TEMP warning light illuminates,
immediately switch off the air conditioner and stop the
vehicle at the nearest safe place. Refer to the “Engine
overheating” section in chapter 9, and “Warning and
indicator lights” section in chapter 3. y If your vehicle has an automatic transmission, avoid
using the accelerator pedal to stay stationary on an
uphill slope instead of using the parking brake or foot
brake. That may cause the transmission fluid to over-
heat. Also, if your vehicle is equipped with an automat- ic transmission, avoid driving with the gear selector le-
ver in “D” when towing a heavy trailer to prevent fluid
overheating. A lower gear should be used. T
Parking on a grade
Always block the wheels under both vehicle and trailer
when parking. Apply the parking brake firmly. You
should not park on a hill or slope. But if parking on a
hill or slope cannot be avoided, you should take the
following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks under both the
vehicle and trailer wheels.
3. When the wheel blocks are in place, release the
regular brakes slowly until the blocks absorb the load.
4. Apply the regular brakes and then apply the park-
ing brake; slowly release the regular brakes.
5. Shift into 1st or reverse gear (manual transmission)
or “P” (automatic transmission) and shut off the en-
gine.

Automatic transmission fluid „Checking the fluid level
The automatic transmission fluid expands largely as
its temperature rises; the fluid level differs according to
fluid temperature. Therefore, there are two different
scales for checking the level of hot fluid and cold fluid
on the dipstick.
Though the fluid level can be checked without warm-
ing up the fluid on the “COLD” range, we recommend
checking the fluid level when the fluid is at operating
temperature. T Checking the fluid level when the fluid is hot
Check the fluid level monthly.
1. Drive the vehicle several miles to raise the temper-
ature of the transmission fluid up to normal operating
temperature; 154 to 176 °F (70 to 80 °C) is normal.
2. Park the vehicle on a level surface and set the park-
ing brake.
3. First shift the selector lever in each position. Then
shift it in the “P” position, and run the engine at idling
