light/malfunction indicator light illu-
minates.
– The AT OIL TEMP warning light
flashes.
– The ABS warning light illumi-
nates.
– The Vehicle Dynamics Control
warning light illuminates.
. If there is a possibility that the
engine could overheat because of a
temperature increase of the engine
coolant, it is not possible to change to
the X-mode. While the vehicle is in the
X-mode, it changes to the Sport (S)
mode when the engine coolant tem-
perature increases.
. It is not possible to activate the X-
mode when the engine is not running,
because the hill descent control func-
tion is not activated.
& Hill descent control function
The hill descent control function will be in
standby mode when the X-mode is acti-
vated and the vehicle speed is less than
approximately 12 mph (20 km/h).
The function will operate when the vehicle

1) Left turn
2) Right turn
.Backing up with a trailer is difficult and
takes practice. 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.
. If the ABS warning light illuminates
while the vehicle is in motion, stop towing
the trailer and have repairs performed
immediately by your nearest SUBARU
dealer. !
Driving on grades
. Before going down a steep hill, slow
down and shift into lower gear (if neces-
sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle’ s brakes. Do not
make sudden downshifts.
. When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating.
. When driving uphill in hot weather, pay
attention to the following indicators be-
cause the engine and transmission are
relatively prone to overheating.: Coolant temperature high warning light
: AT OIL TEMP warning light (CVT models)
If the coolant temperature high warning
light and/or the AT OIL TEMP warning light
illuminates, immediately turn off the air
conditioner and stop the vehicle in the
nearest safe location. For further instruc-
tions and additional information, refer to
the following sections. –“If you park your vehicle in case of
an emergency ”F 9-2
–“ Engine overheating ”F 9-12
–“ Coolant temperature low indicator
light/Coolant temperature high warn-
ing light ”F 3-17 –“
AT OIL TEMP warning light (CVT
models) ”F 3-19
. For CVT models, 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 overheat.
! 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. 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 parking brake; slowly release
the regular brakes.
5. Shift into 1st or reverse gear (MT
models) or “P ” position (CVT models)
and shut off the engine.

In case of emergency/Engine overheating
Engine overheating
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
is under pressure. Removing the
cap while the engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.
If the engine overheats, safely pull off the
road and stop the vehicle in a safe
location.
& If steam is coming from the
engine compartment
. Turn off the engine and get everyone
away from the vehicle until it cools down.
. Contact an authorized SUBARU deal-
er.
& If no steam is coming from
the engine compartment
1. Keep the engine running at idling
speed.
2. Open the engine hood to ventilate the engine compartment. Refer to
“Engine
hood ”F 11-7.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact an authorized
SUBARU dealer for repair.
3. After the coolant temperature high
warning light that has blinked or illumi-
nated in REDturns off, turn off the engine.
For details about the warning light, refer to
“Coolant temperature low indicator light/
Coolant temperature high warning light ”
F 3-17.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank. If the coolant level is below the
“LOW ”mark, add coolant up to the “FULL ”
mark.
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to “Engine coolant ”F 11-13.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.

erative. NEVER use a circuit
tester for this wiring. If your
SRS airbag or seatbelt preten-
sioner needs service, consult
your nearest SUBARU dealer.
NOTE
SUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against
performing these services on a
SUBARU vehicle. Non-SUBARU ap-
proved flushing systems use chemi-
cals and/or solvents which have not
been tested or approved by SUBARU.
SUBARU warranties do not cover any
part of the vehicle which is damaged by
adding or applying chemicals and/or
solvents other than those approved or
recommended by SUBARU.
&Before checking or servicing
in the engine compartment
WARNING
. Always stop the engine and set
the parking brake firmly to pre-
vent the vehicle from moving.
. Always let the engine cool down.
Engine parts become very hot when the engine is running and
remain hot for some time after
the engine has stopped.
. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
. Always remove the key from the
ignition switch. When the ignition
switch is in the “ON ”position,
thecoolingfanmayoperate
suddenly even when the engine
is stopped. If your body or
clothes come into contact with a
rotating fan, that could result in
serious injury.
. Before performing any servicing
on a vehicle equipped with a
remote engine start system (a
dealer option), temporarily place
the remote engine start system in
service mode to prevent it from
unexpectedly starting the engine.
CAUTION
. Do not contact the drive belt
cover while checking the compo-
nents in the engine compart-
ment. Doing so may cause your
hand to slip off the cover and
result in an unexpected injury.
. Do not touch the oil filter until the
engine has cooled down comple-
tely. Doing so may result in a
burn or other injury. Note that the
oil filter becomes very hot when
the engine is running and re-
mains hot for some time after
the engine has stopped.

Maintenance and service/Cooling system
in hot weather, oil of higher viscosity is
required to properly lubricate the en-
gine.
&Synthetic oil
You should 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
classification, viscosity and grade shown
in this Owner ’s Manual. Refer to “Engine
oil ”F 12-4. Also, you must follow the oil
and filter changing intervals shown in the
Warranty and Maintenance booklet.
NOTE
Synthetic oil of the grade and viscosity
noted in chapter 12 is the recom-
mended engine oil for optimum engine
performance. Conventional oil may be
used if synthetic oil is unavailable.
Cooling system
WARNING
Never attempt to remove the radia-
tor 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 boil-
ing hot coolant when the cap is
removed.
CAUTION
. Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). This coolant
should not be mixed with any
other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. Should it be
necessary to top up the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand or type, the maintenance interval is
shortened to that of the mixing
coolant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Cooling fan, hose and con-
nections
Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the coolant temperature high
warning light blinks or illuminates in RED,
the cooling fan circuit may be defective.
Refer to “Coolant temperature low indica-
tor light/Coolant temperature high warning
light ”F 3-17.
Check the fuse and replace it if necessary.
Refer to “Fuses”F 11-37 and “Fuses and
circuits ”F 12-12.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
