Driving tips
when towing a trailer and you should never
speed. You should also keep the following tips
in mind:
T Before starting out on a trip
y Check that the vehicle and vehicle-to-hitch mount-
ing are in good condition. If any problems are appar-
ent, do not tow the trailer. y Check that the vehicle sits horizontally with the trail-
er attached. If the vehicle is tipped sharply up at the
front and down at the rear, check the total trailer
weight, GVW, GAWs and tongue load again, then con-
firm that the load and its distribution are acceptable.y Check that the tire pressures are correct.
y Check that the vehicle and trailer are connected
properly. Confirm that – the trailer tongue is connected properly to the
hitch ball.
– the trailer lights connector is connected properly
and trailer’s brake lights illuminate when the vehi-
cle’s brake pedal is pressed, and that the trailer’s
turn signal lights flash when the vehicle’s turn signal
lever is operated.
– the safety chains are connected properly.
– all cargo in the trailer is secured safety in position.
– the side mirrors provide a good rearward field of view without a significant blind spot.
y Sufficient time should be taken to learn the “feel” of
the vehicle/trailer combination before starting out on a
trip. In an area free of traffic, practice turning, stopping
and backing up. T Driving with a trailer
y You should allow for considerably more stopping
distance when towing a trailer. Avoid sudden braking
because it may result in skidding or jackknifing and
loss of control. y Avoid abrupt starts and sudden accelerations. If
your vehicle has a manual transmission, always start
out in first gear and release the clutch at moderate en-
gine revolution. y Avoid uneven steering, sharp turns and rapid lane
changes. y Slow down before turning. Make a longer than nor-
mal turning radius because the trailer wheels will be
closer than the vehicle wheels to the inside of the turn.
In a tight turn, the trailer could hit your vehicle. y Crosswinds will adversely affect the handling of
your vehicle and trailer, causing sway. Crosswinds
can be due to weather conditions or the passing of
large tracks or buses. If swaying occurs, firmly grip the
steering wheel and slow down immediately but gradu-
ally. y When passing other vehicles, considerable dis-

tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
1) Left turn
2) Right turn
y 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. y 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. T
Driving on grades
y 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.y When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating.y 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. y 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

Driving tips
overheating. A lower gear should be used. T
Parking on a grade
Always block the wheels under both vehicle and trailer
when parking. Apply the parking brake firmly. You
should not park on a hill or slope. But if parking on a
hill or slope cannot be avoided, you should take the
following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks under both the
vehicle and trailer wheels.
3. When the wheel blocks are in place, release the
regular brakes slowly until the blocks absorb the load.
4. Apply the regular brakes and then apply the park-
ing brake; slowly release the regular brakes.
5. Shift into 1st or reverse gear (manual transmission)
or “P” (automatic transmission) and shut off the en-
gine.

In case of emergency
1) Spare fuse
2) FWD connector
NOTE
(If your vehicle is AWD with automatic transmis-
sion, except Turbo models) Before driving your
vehicle with the temporary spare tire, put a spare fuse inside the FWD connector in the main fuse
box located in the engine compartment and con-
firm that the Front-wheel drive warning light
“AWD” in the combination meter comes on. The
all wheel drive capability of the vehicle has now
deactivated. After re-installing the conventional
tire, remove the spare fuse from the FWD connec-
tor in order to reactivate all wheel drive.
Never tow a trailer when the temporary spare
tire is used. The temporary spare tire is not de-
signed to sustain the towing load. Use of the
temporary spare tire when towing can result in
failure of the spare tire and/or less stability of
the vehicle and may lead to an accident.
Never use any temporary spare tire other than
the original. Using other sizes may result in se-
vere mechanical damage to the drive train of
your vehicle.

Maintenance and service
„
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.
Cooling system
Never attempt to remove the radiator cap until
the engine has been shut off and has cooled
down completely. Since the coolant is under
pressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap is re-
moved.
y The cooling system has been filled at the fac-
tory with a high quality, corrosion-inhibiting,
year-around coolant which provides protection
against freezing down to –33 °F (–36 °C). For
adding, use genuine SUBARU coolant or an
equivalent: a mixture of 50% soft water and 50%
ethylene-glycol basis 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 dif-
ferent kinds of coolant. y Do not splash the engine coolant over paint-

Maintenance and service
y
Abnormally low tire pressure (tread worn at
shoulders)
Rolling resistance is high, so fuel consumption is also
higher. y
Abnormally high tire pressure (tread worn in cen-
ter)
Ride comfort is poor. Also, the tire magnifies the ef-
fects of road-surface bumps and dips, possibly result-
ing 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.
Driving at high speeds with excessively low tire
pressures can cause the tires to deform severe-

left hand side of the vehicle. (Each tire must be
kept on its original side of the vehicle.) Replace
any damaged or unevenly worn tire at the time of
rotation. After tire rotation, adjust the tire pres-
sures and make sure the wheel nuts are correct-
ly tightened. A tightening torque specification
and a tightening sequence specification for the
wheel nuts can be found “Flat tires” in Chapter 9. „Vehicle load limit – how to determine
The load capacity of your vehicle is determined
by weight, not by available cargo space. The
load limit of your vehicle is shown on the vehicle
placard attached to the driver’s side B-pillar. Lo-
cate the statement “The combined weight of oc-
cupants and cargo should never exceed XXX kg
or XXX lbs” on your vehicle’s placard.
The vehicle placard also shows seating capacity
of your vehicle.
The total load capacity includes the total weight
of driver and all passengers and their belong-
ings, 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 ca- pacity can be calculated by the following method.
Cargo capacity = Load limit – (total weight of oc-
cupants + total weight of optional equipment +
tongue load of a trailer (if applicable))
For towing capacity information and weight lim-
its, refer to “Trailer towing” in Chapter 8. T
Calculating total and load capacities vary-
ing seating configurations

number of occupants to two), the calculations
are as follows:
1. Calculate the total weight.
2. Calculate the available load capacity.
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 plac-
ard with the statement “The combined weight of
occupants and cargo should never exceed 408
kg or 900 lbs”.
For example, the vehicle has one occupant
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
Total weight = 154 lbs (70 kg) + 176 lbs (80 kg) + 662 lbs (300 kg) =
992 lbs (450 kg) (Occupant)
(Cargo)
Available Load Capacity
= 900 lbs (408 kg) – 992 lbs (450 kg) = –92 lbs (–42 kg) (Vehicle
capacity weight) (Total weight)
