Do not let dust, oil or water get on or in the
transmitter when re placing the battery.

„Replacing
„ Lost transmitters (keyless entry system)If you lose a transmitter or want to purchase additional
transmitters (up to four can be programmed), you
should re-program all of your transmitters for security
reasons. It is recommended that you have your dealer
program all of your transmitters into your system. TProgramming the transmitters
The keyless entry system is equipped with a special
code learning feature that allows you to program new
transmitter codes into the system or to delete old
ones. The system can learn up to four unique transmit-
ter codes. The four transmitter codes may be the same or different. Programming transmitter codes into system:

Oil capacity (Guideline):
4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only a guideline.
The necessary quantity of o il 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 use the dipstick to
confirm that the level is correct.
14.Start the engine and make sure that no oil leaks ap-
pear around the filter’s rubber seal and drain plug.
15.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
again and if necessary, add more engine oil. „ Recommended grade and viscosity

„ Oil grade and viscosity
Use only engine oil with the recommended
grade and viscosity.
Oil grade:
ILSAC GF-4, which can be identified with the IL-
SAC certification mark (Starburst mark)
or API classification SM with the words “ENERGY
CONSERVING”
These recommended oil grades can be identified by
looking for either or both of the following marks dis-
played on the oil container.

1) Indicates the oil quality by API designations
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil
has fuel saving capabilities
In choosing an oil, you want the proper quality and vis-
cosity, as well as one that will add to fuel economy.
The following table lists the recommended viscosities
and applicable temperatures.
When adding oil, different brands may be used togeth-
er as long as they are the same API classification and
SAE viscosity as those recommended by SUBARU. SAE viscosity No. and applicable temperature
*: 5W-30 is preferred.
Engine oil viscosity (thickness) affects fuel economy.
Oils of lower viscosity pr ovide better fuel economy.
However, in hot weather, oil of higher viscosity is re-
quired to properly lubricate the engine. „ Recommended grade and viscosity

high temperatures, or used for heavy-duty applica-
tions such as towing a trailer, use of oil with the follow-
ing grade and viscosities is recommended.

„ Checking the fluid level„Checking
„ Fluid levelThe 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; 158 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
speed.

yBe careful not to spill re ar differential gear oil
when adding it. If rear differential gear oil
touches the exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If rear differential
gear oil gets on the exhaust pipe, be sure to
wipe it off.y If the vehicle requires frequent refilling, there
may be an oil leak. If you suspect a problem,
have the vehicle checked at your SUBARU deal-
er.
Your vehicle may be equipped with a rear differential
protector. The differential protector provides protec-
tion to the rear differential assembly during off-road
use. Removal of the rear differential protector is not re-
quired when checking the oil level.
