Loading Your Vehicle
298
NOTEFor better fuel economy, do not carry
unneeded cargo.
■ Vehicle Capacity WeightThe load capacity of your vehicle is deter-
mined by weight, not by available cargo
space. The maximum load you can carry
in your vehicle is shown on the tire infla-
tion pressure label attached to the driver’s
side center pillar. It includes the total
 Stow cargo and luggage in the
trunk whenever possible. To prevent cargo and luggage
from sliding forward during
braking, do not stack anything in
the enlarged trunk. Keep cargo
and luggage low, as close to the
floor as possible. When you carry something inside
the vehicle, secure it whenever
you can to prevent it from being
thrown around inside the vehicle
during sudden stops, sharp turns
or in an accident. Secure long items properly to
prevent them from shooting
forward and causing serious
injury during a sudden stop. Never exceed the maximum load
limit. If you do, some parts on
your vehicle can break, or it can
change the way your vehicle
handles. This could result in loss
of control and cause personal
injury. Also, overloading can
shorten the life of your vehicle.
 Do not place cargo or luggage in
or on the following locations as
the item may get under the clutch,
brake, or accelerator pedal and
prevent the pedals from being
depressed properly, block the
driver’s vision, or hit the driver or
passengers, causing an accident:
- At the feet of the driver- On the front passenger or rear
seats (when stacking items)- On the rear shelf- On the instrument panel- On the dashboard
CAUTION
Do not carry spray cans, containers
with flammable or corrosive liquids
or any other dangerous items inside
the vehicle.

weight of the driver and all passengers,
their belongings, and any optional equip-
ment.■ GVWR and GAWR (Gross
Veh icle Weight Rating an d
Gross Axle Weight Rating)Certification labelThe certification label attached to the
driver’s side center pillar shows GVWR
(Gross Vehicle Weight Rating) and
GAWR (Gross Axle Weight Rating).
The GVW (Gross Vehicle Weight) must
never exceed the GVWR. GVW is the
combined total of weight of the vehicle,
fuel, driver, all passengers, luggage, and
any optional equipment. Therefore, the
GVW changes depending on the situation. In addition, the tota
l weight applied to
each axle (GAW) must never exceed the
GAWR. The front and rear GAWs can be
adjusted by relocating luggage inside the
vehicle.
Even if the total weight of your luggage is
lower than the vehicl e capacity weight,
either front or rear GAW may exceed the
GAWR, depending on the distribution of
the luggage.
When possible, the load should be evenly
distributed throughout the vehicle.
If you carry heavy loads in the vehicle, you
should confirm that GVW and front and
rear GAWs are within the GVWR and
GAWR by putting your vehicle on a
vehicle scale, found at a commercial
weighing station.
Do not use replacement tires with a lower
load range than the originals because
they may lower the GVWR and GAWR
limitations. Replacement tires with a
higher load range than the originals do not
increase the GVWR and GAWR limita-
tions.
8-10. Trailer TowingSUBARU assumes no responsibility for
injuries or vehicle damage that may result
from trailer towing, from any trailer towing
equipment or from any errors or omissions
in the instructions accompanying such
equipment. SUBARU warranties do not
apply to vehicle damage or malfunction
caused by trailer towing.

CAUTION
Your vehicle is neither designed nor
intended to be used for trailer tow-
ing. Therefore, never tow a trailer
with your vehicle.

Engine Oil
34611-6. Engine Oil■Engine Oil ConsumptionSome engine oil will be consumed while
driving. The rate of consumption can be
affected by such factors as transmission
type, driving style, terrain and tempera-
ture. Under the followi ng conditions, oil
consumption can be increased and thus
require refilling between maintenance
intervals:
 When the engine is new and within the
break-in period
 When the engine oil is of lower quality 
When the incorrect oil viscosity is used
 When engine braking is employed
(repeatedly)
 When the engine is operated at high
engine speeds (for extended periods of
time)
 When the engine is operated under
heavy loads (for extended periods of time)
 When the engine idles for extended
periods of time
 When the vehicle is operated in stop
and go and/or heavy traffic situations
 When the vehicle is used under severe
thermal conditions
 When the vehicle accelerates and
decelerates frequently
Under these or similar conditions, you
should check your oil at least every 2nd
fuel fill-up and change your engine oil
more frequently. Different drivers in the
same car may experience different
results. If your oil consumption rate is
greater than expected, contact your
authorized SUBARU retailer who may
perform a test under controlled conditions.
■ Checking the Oil Level1. Park the vehicle on a level surface and
stop the engine. If you check the oil level
just after stopping the engine, wait for at least 5 minutes for the oil to drain back into

the oil pan before checking the level.
1) Oil level gauge
2) Oil filler cap
3) Oil filter2. Pull out the level gauge, wipe it clean,
and insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.
CAUTION
 If the level gauge is not pulled out
easily, twist the level gauge right
and left, then pull it out. Other-
wise, you may be injured acciden-
tally straining yourself. Use only engine oil with the
recommended grade and
viscosity. Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
CAUTION
If the level gauge cannot be pulled
out easily, twist the level gauge
right and left, then gently pull it out.
Otherwise, you may be injured acci-
dentally straining yourself.

Imp qt) from low level to full level
4. Pull out the oil level gauge again.
5. Check the oil levels on both sides of
the level gauge. The engine oil level must
be judged by the lowest of the two levels.
If the oil level is below the low level mark,
add oil so that the full level is reached. To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level is

correct.
NOTE To prevent overfilling the engine oil,
do not add any additional oil above the
full level when the engine is cold.
■ Changing the Oil and Oil
FilterChange the oil and oil filter according to
the maintenance schedule in the
“Warranty and Maintenance Booklet”.
NOTE Changing the engine oil and oil filter
should be performed by a well-trained
expert. Contact your SUBARU dealer
for changing the engine oil and oil
filter. Fully trained mechanics are on
standby at a SUBARU dealer to utilize
the special tools, spare parts and
recommended oil for this work, and
also, used oils are properly disposed
of.
 If performing oil replacement your-
self, observe the local regulations and
dispose of waste oil properly.■ Recommended Grade and
ViscosityRefer to "Engine Oil" P381.NOTEEngine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. How-
ever, in hot weather, oil of higher vis-
cosity is required to properly lubricate
the engine.
CAUTION
 Be careful not to touch the engine
oil filter when removing the oil
filler cap. Doing so may result in a
burn, a pinched finger, or may
cause some other injury.

Check the fuse and replace it if necessary.
Refer to "Fuses" P371. If the fuse is not
blown, have the cooling system checked
by your SUBARU dealer.
If the frequent addition of coolant is neces-
sary between vehicle service visits, it is
recommended that you have your vehicle
inspected by an authorized SUBARU
dealer to check for leaks, damage, or
looseness.■ Engine Coolant▼ Checking the coolant level1) “FULL” level mark
2) “LOW” level mark
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the
“LOW” level mark, add coolant up to the
“FULL” level mark. If the reserve tank is
empty, remove the radiator cap and refill
coolant up to just below the filler neck as
shown in the following illustration.
1) Fill up to this level.
3. After refilling the reserve tank and the
radiator, reinstall t he cap and check that
the rubber gaskets in side the radiator cap
are in the proper position.

CAUTION
 Be careful not to spill engine
coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
