SAE viscosity number and applicable
temperature
*: 5W-30 is recommended.
Engine oil viscosity (thickness) affects fuel
economy. Oils of lower viscosity provide
better fuel economy. However, in hot
weather, oil of higher viscosity is required
to properly lubricate the engine.
„ Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in ar- eas with very high temperatures, or used
for heavy-duty applications such as tow-
ing a trailer, use of oil with the following
grade and viscosities is recommended.
API classification SM (or SL):
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 syn-
thetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner’s Manual, and must follow
the oil and filter changing intervals shown
in the maintenance schedule.
Cooling system
Use only engine oil with the recom-
mended grade and viscosity.

Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.
The cooling system has been filled
at the factory with a high quality,
corrosion-inhibiting, year-around
coolant which provides protection
against freezing down to –33 qF
(–36 qC). For adding, use genuine
SUBARU coolant or an equivalent: a
mixture of 50% soft water (or clear
and drinkable water) and 50% phos-
phate or non-amine type coolant.
Use of improper coolants may result
in corrosion in the cooling system. It
is important to maintain protection
against freezing and corrosion,
even if freezing temperatures are
not expected. Never mix different
kinds of coolant.

yAbnormally low tire pressure (tread
worn at shoulders)
Rolling resistance is high, so fuel con-
sumption is also higher. y
Abnormally high tire pressure (tread
worn in center)
Ride comfort is poor. Also, the tire magni-
fies the effects of road-surface bumps and
dips, possibly resulting in vehicle damage.
If the tire placard shows tire pressures for
the vehicle when fully loaded and for the
vehicle when towing a trailer, adjust the
tire pressures to the values that match
current loading conditions.
„ Wheel balance
Each wheel was correctly balanced when
your vehicle was new, but the wheels will
become unbalanced as the tires become
worn during use. Wheel imbalance caus-
es the steering wheel to vibrate slightly at
certain vehicle speeds and detracts from
the vehicle’s straight-line stability. It can
also cause steering and suspension sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not cor-
rectly balanced, have them checked and
adjusted by your SUBARU dealer. Also
have them adjusted after tire repairs and
after tire rotation.
NOTE
Loss of correct wheel alignment* caus-
es the tires to wear on one side and re-
duces the vehicle’s running stability.
B00051B00052
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and destruction of
the tires. The resulting loss of vehi-
cle control could lead to an acci-
dent.

„Vehicle load limit – how to de-
termine
The load capacity of your vehicle is
determined by weight, not by avail-
able cargo space. The load limit of
your vehicle is shown on the vehicle
placard attached to the driver’s side
B-pillar. Locate the statement “The
combined weight of occupants and
cargo should never exceed XXX kg or
XXX lbs” on your vehicle’s placard.
The vehicle placard also shows seat-
ing capacity of your vehicle.
The total load capacity includes the
total weight of driver and all passen-
gers and their belongings, any cargo,
any optional equipment such as a
trailer hitch, roof rack or bike carrier,
etc., and the tongue load of a trailer.
Therefore cargo capacity can be cal-
culated by the following method.
Cargo capacity = Load limit – (total
weight of occupants + total weight of
optional equipment + tongue load of a
trailer (if applicable))
For towing capacity information and
weight limits, refer to “Trailer towing”
in Chapter 8. T
Calculating total and load capac-
ities varying seating configura- tions
Calculate the available load capacity
as shown in the following examples:
Example 1A
Vehicle capacity weight of the vehicle
is 900 lbs (408 kg), which is indicated
on the vehicle placard with the state-
ment “The combined weight of occu-
pants and cargo should never exceed
900 lbs or 408 kg”.
For example, if the vehicle has one
occupant weighing 154 lbs (70 kg)
plus cargo weighing 662 lbs (300 kg). 1. Calculate the total weight.
2. Calculate the available load capac-
ity by subtracting the total weight from
the vehicle capacity weight of 900 lbs
(408 kg).
3. The result of step 2 shows that a
further 84 lbs (38 kg) of cargo can be
carried.
D00106
Total weight = 154 lbs (70 kg) + 662 lbs (300 kg) =
816 lbs (370 kg)(Occupant) (Cargo)

Example 1B
For example, if a person weighing 176
lbs (80 kg) now enters the same vehi-
cle (bringing the number of occupants
to two), the calculations are as fol-
lows:
1. Calculate the total weight.
2. Calculate the available load capac-
ity.
3. The total weight now exceeds the
capacity weight by 92 lbs (42 kg), so
the cargo weight must be reduced by
92 lbs (42 kg) or more.
Example 2A
Vehicle capacity weight of the vehicle
is 900 lbs (408 kg), which is indicated on the vehicle placard with the state-
ment “The combined weight of occu-
pants and cargo should never exceed
408 kg or 900 lbs”.
For example, the vehicle has one oc-
cupant weighing 165 lbs (75 kg) plus
cargo weighing 375 lbs (170 kg). In
addition, the vehicle is fitted with a
trailer hitch weighing 22 lbs (10 kg), to
which is attached a trailer weighing
1,764 lbs (800 kg). 10% of the trailer
weight is applied to the trailer tongue
(i.e. Tongue load = 176 lbs (80 kg)).
1. Calculate the total weight.
2. Calculate the available load capac-
ity.
D00107
Total weight = 154 lbs (70 kg) + 176 lbs (80 kg) + 662 lbs (300 kg) =
992 lbs (450 kg) (Occupant)
(Cargo)
D00108
Total weight = 165 lbs (75 kg) + 375 lbs (170 kg) + 22 lbs (10 kg) + 176 lbs (80 kg)= 738 lbs (335 kg) (Occupant) (Cargo)
(Trailer hitch) (Tongue load)

3. The result of step 2 shows that a
further 162 lbs (73 kg) of cargo can be
carried.
Example 2B
For example, if a person weighing 143
lbs (65 kg) and a child weighing 40 lbs
(18 kg) now enter the same vehicle
(bringing the number of occupants to
three), and a child restraint system
weighing 11 lbs (5 kg) is installed inthe vehicle for the child to use, the cal-
culations are as follows:
1. Calculate the total weight.
2. Calculate the available load capac-
ity.
3. The total weight now exceeds the
capacity weight by 32 lbs (15 kg), so
the cargo weight must be reduced by
32 lbs (15 kg) or more.
„ Determining compatibility of
tire and vehicle load capaci-
ties
The sum of four tires’ maximum load
ratings must exceed the maximum
loaded vehicle weight (“GVWR”). In
addition, sum of the maximum load
ratings of two front tires and of two
rear tires must exceed each axle’s
maximum loaded capacity (“GAWR”).
Original equipment tires are designed
to fulfill those conditions.
The maximum loaded vehicle weight
is referred to Gross Vehicle Weight
Rating (GVWR). And each axle’s
maximum loaded capacity is referred
to Gross Axle Weight Rating
(GAWR). The GVWR and each axle’s
GAWR are shown on the vehicle cer-
tification label affixed to the driver’s
door.
The GVWR and front and rear
GAWRs are determined by not only
the maximum load rating of tires but
also loaded capacities of the vehicle’s

suspension, axles and other parts of
the body.
Therefore, this means that the vehicle
cannot necessarily be loaded up to
the tire’s maximum load rating on the
tire sidewall. „Adverse safety consequenc-
es of overloading on handling
and stopping and on tires
Overloading could affect vehicle han-
dling, stopping distance, vehicle and
tire as shown in the following. This
could lead to an accident and possibly
result in severe personal injury. y Vehicle stability will deteriorate.
y Heavy and/or high-mounted loads
could increase the risk of rollover. y Stopping distance will increase.
y Brakes could overheat and fail.
y Suspension, bearings, axles and
other parts of the body could break or
experience accelerated wear that will
shorten vehicle life. y Tires could fail.
y Tread separation could occur.
y Tire could separate from its rim. „
Steps for Determining Cor-
rect Load Limit
1. Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXX pounds” on
your vehicle’s placard.
2. Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
3. Subtract the combined weight of
the driver and passengers from XXX
kilograms or XXX pounds.
4. The resulting figure equals the
available amount of cargo and lug-
gage load capacity. For example, if
the “XXX” amount equals 1,400 lbs
(635kg). and there will be five- 150 lbs
(68 kg) passengers in your vehicle,
the amount of available cargo and
luggage load capacity is 650 lbs.
(1,400 – 750 (5 u 150) = 650 lbs)
5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not safe-
ly exceed the available cargo and lug-
gage load capacity calculated in Step4.
6. If your vehicle will be towing a trail-
er, load from your trailer will be trans- ferred to your vehicle. Consult this
manual to determine how this reduc-
es the available cargo and luggage
load capacity of your vehicle.
