ing a shutdown. "When the actual ambient temperature falls outside
the specified indicator range.Warning and indicator lights
Several of the warning and indicator lights come on
momentarily and then go out when the ignition switch
is initially turned to the “ON” position. This permits
checking the operation of the bulbs.
Apply the parking brake and turn the ignition switch to
the “ON” position. The following lights come on:
Seatbelt warning light
SRS airbag system warning light
CHECK ENGINE warning light/Malfunction indica- tor lamp
Charge warning light
Oil pressure warning light
AT OIL temperature warning light (AT vehicles)ABS warning light
Brake system warning light
If any lights fail to come on, it indicates a burned-out
bulb or a malfunction of the corresponding system.
Consult your authorized SUBARU dealer for repair. ! Seatbelt warning light and chime
When the ignition switch is turned to the “ON” position,
the seatbelt warning light will come on and the remind-
er chime will sound for about six seconds to remind the

Instruments and controls
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.
NOTE " 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. "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.
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
system continues to operate normally." The warning light does not come on when the
ignition switch is turned to the “ON” position." The warning light comes on when the ignition switch is turned to the “ON” position, but it
does not go out even when the vehicle speed
exceeds approximately 8 mph (12 km/h)."
The warning light comes on during driving.
If these occur, have the ABS system repaired at
the first available opportunity by your SUBARU
dealer.
With a vehicle equipped with an EBD system, the ABS
warning light comes on together with the brake system
warning light if the EBD system becomes faulty. For
further details of the EBD system fault warning, refer to “Brake system warning light”.
NOTE
If the warning light behavior is as described be-
low, the ABS system may be considered normal." The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off." The warning light remains on after the engine
has been started, but it goes out when the vehicle
speed reaches about 8 mph (12 km/h)." The warning light comes on during driving, but
it goes out immediately and remains off.

Starting and operating
When facing downhill, the front wheels should be
turned into the curb.
"
Never leave unattended children or pets in
the vehicle. They could accidentally injure
themselves or others through inadvertent oper-
ation of the vehicle. Also, on hot or sunny days,
the temperature in a closed vehicle could
quickly become high enough to cause severe
or possibly fatal injuries to people. " Do not park the vehicle over flammable mate-
rials such as dry grass, waste paper or rags, as they may burn easily if they come near hot en-
gine or exhaust system parts. "
Be sure to stop the engine if you take a nap in
the vehicle. If engine exhaust gas enters the
passenger compartment, occupants in the ve-
hicle could die from carbon monoxide (CO)
contained in the exhaust gas.
If your vehicle has a front underspoiler and rear
underspoiler (both optional), pay attention to
blocks and other obstructions on the ground
when parking. The underspoilers could be dam-
aged by contact with them.

operating it off-road and not using common sense pre-
cautions such as those listed above is not eligible for
warranty coverage."Wash the vehicle’s underbody after off-road driving.
Suspension components are particularly prone to dirt
buildup, so they need to be washed thoroughly.Winter driving ! Operation during cold weather
Carry some emergency equipment, such as tire
chains, a window scraper, a bag of sand, flares, a
small shovel, and jumper cables.
Check the battery and cables. Cold temperatures re-
duce battery capacity. The battery must be in good
condition to provide enough power for cold winter starts.
Use an engine oil of proper grade and viscosity for
cold weather. Heavy summer oil will cause harder

Driving tips

tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
1) Left turn
2) Right turn
" Backing up with a trailer is difficult and takes prac-
tice. When backing up with a trailer, never accelerate
or steer rapidly. When turning back, grip the bottom of
the steering wheel with one hand and turn it to the left
for a left turn, and turn it to the right for a right turn." If the ABS warning light illuminates while the vehicle
is in motion, stop towing the trailer and have repairs
performed immediately by the nearest SUBARU deal-er. !
Driving on grades
" 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. " When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating. " 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." 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

Non-turbo models
7. Remove the oil filter with an oil filter wrench.
8. Before installing a new oil filter, apply a thin coat of
engine oil to the seal.
9. Clean the rubber seal seating area of the lower
crank case/oil cooler (For Turbo) and install the oil fil-
ter by hand turning. Be careful not to twist or damage
the seal.
10.Tighten it approximately two-thirds of a turn after
the seal makes contact with the lower crank case/oil
cooler (For Turbo).
Never over tighten the oil filter because that canresult in an oil leak.
11.Reinstall under cover (For Turbo).
12.Pour engine oil through the filler neck.
Oil capacity (guideline): Non-turbo models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
Turbo models:
4.8 US qt (4.5 liters, 4.0 Imp qt)
The oil quantity indicated above is only guideline.
The necessary quantity of oil depends on the quantity
of oil that has been drained. The quantity of drained oil
differs slightly depending on the temperature of the oil
and the time the oil is left flowing out. After refilling the
engine with oil, therefore, you must the dipstick to con-
firm that the level is correct.
13.Start the engine and make sure that no oil leaks ap-
pear around the filter’s rubber seal and drain plug.
14.Run the engine until it reaches the normal operat-
ing temperature. Then stop the engine and wait a few
minutes to allow the oil drain back. Check the oil level
