Driving tips
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 winterstarts.
Use an engine oil of proper grade and viscosity for
cold weather. Heavy summer oil will cause harder starting.
Keep the door locks from freezing by squirting them
with deicer or glycerin.
Forcing a frozen door open may damage or separate
the rubber weather strips around the door. If the door
is frozen, use hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that contains an anti-
freeze solution. Do not use engine antifreeze or other
substitutes because they may damage the paint of the vehicle. T
Before driving your vehicle
Before entering the vehicle, remove any snow or ice
from your shoes because that could make the pedals
slippery and dangerous.
While warming up the vehicle before driving, check
that the accelerator pedal, brake pedal, and all other
controls operate smoothly.
Clear away ice and snow that has accumulated under
the fenders to avoid making steering difficult. During
severe winter driving, stop when and where it is safe
to do so and check under the fenders periodically.

Checking the oil level
Check the engine oil level at each fuel stop.
1. Park the vehicle on a level surface and stop the en-
gine.
2. Pull out the dipstick, wipe it clean, and insert it
again.
3. Be sure the dipstick is correctly inserted until it
stops with the graphic symbol “ ” on its top ap-
pearing as shown in the illustration. A) Notch
B) Upper level
C) Lower level
4. Pull out the dipstick again and check the oil level on
it. If it is below the lower level, add oil to bring the level
up to the upper level.
y Use only engine oil with the recommended
grade and viscosity. y Be careful not to spill engine oil when adding
it. If oil touches the exhaust pipe, it may cause

Never over tighten the oil filter because that can
result in an oil leak.
11.Close the access cover by turning it clockwise and
reinstall the six clips in their original positions.
12.Pour engine oil through the filler neck.
Oil quantity (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 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 pouring oil
into the engine, therefore, you must use the dipstick to
confirm that the level is correct.
13.Start the engine and make sure that no oil leaks ap- pear around the filter’s rubber seal.
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
again and if necessary, add more engine oil. „
Recommended grade and viscosity
Oil grade:
ILSAC GF-3, which can be identified with the new
API certification mark (Starburst mark)
or API classification SL with the words “ENERGY
CONSERVING” (if you cannot obtain the oil with
SL grade, you may use SJ grade “ENERGY CON-
SERVING” oil).
These recommended oil grades can be identified by
looking for either or both of the following marks dis-
played on the oil container.
Oil filter color Part number Amount of rotation
Black 15208AA080 1 rotation
White 15208AA09A 2/3 – 3/4 rotation

A) Indicates the oil quality by API designations
B) Indicates the SAE oil viscosity grade
C) Indicates that the oil has fuel saving capabilities
New API Certification Mark (Starburst Mark)
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 number and applicable temperature
*: 5W-30 is preferred.
Engine oil viscosity (thickness) affects fuel economy.
Oils of lower viscosity provide better fuel economy.
However, in hot weather, oil of higher viscosity is re-
quired to properly lubricate the engine.
Use only engine oil with the recommended
grade and viscosity. „
Recommended grade and viscosity
under severe driving conditions
If the vehicle is used in desert areas, in areas with very
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.
API classification SL (or SJ):
SAE viscosity No.:
30, 40, 10W-50, 20W-40, 20W-50
„ Synthetic oil
You can use synthetic engine oil that meets the same
requirements given for conventional engine oil. When
using synthetic oil, you must use oil of the same clas-
sification, viscosity and grade shown in this owner’s
manual, and must follow the oil and filter changing in-
tervals shown in the maintenance schedule.
