Towing
If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following
procedures for safety.
WARNING
Never tow AWD models (both AT and
MT) with the front wheels raised off
the ground while the rear wheels are
on the ground, or with the rear
wheels raised off the ground while
the front wheels are on the ground.
This will cause the vehicle to spin
away due to the operation or dete-
rioration of the center differential. &
Towing and tie-down hooks
The towing hooks should be used only in
an emergency (e.g., to free a stuck vehicle
from mud, sand or snow).
CAUTION
. Use only the specified towing
hook and tie-down hook. Never
use suspension parts or other
parts of the body for towing or
tie-down purposes.
. To prevent deformation to the
front bumper and the towing
hook, do not apply excessive
lateral load to the towing hook.
Front towing hook (non-turbo models):
1. Take the towing hook out of the tool
bucket and take the screwdriver out of the
tool bag. Take the jack handle out of the
trunk (4-door) or cargo area (5-door).
2. Pry off the cover on the front bumper
using a screwdriver, and you will find a
threaded hole for attaching the towinghook.
3. Screw the towing hook into the thread
hole until its thread can no longer be seen.

Maintenance schedule
The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the“Warranty and Main-
tenance Booklet ”.
For details of your maintenance schedule,
read the separate “Warranty and Main-
tenance Booklet ”. Maintenance precautions
When maintenance and service are re-
quired, it is recommended that all work be
done by an authorized SUBARU dealer.
If you perform maintenance and service
by yourself, you should familiarize yourself
with the information provided in this
section on general maintenance and
service for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
WARNING
. Testing of an All-Wheel Drive
model must NEVER be per-
formed on a single two-wheel
dynamometer or similar appara-
tus. Attempting to do so will
result in transmission damage
and in uncontrolled vehicle
movement and may cause an
accident or injuries to persons
nearby.
. Always select a safe area when
performing maintenance on yourvehicle. .
Always be very careful to avoid
injury when working on the vehi-
cle. Remember that some of the
materials in the vehicle may be
hazardous if improperly used or
handled, for example, batteryacid.
. Your vehicle should only be ser-
viced by persons fully competent
to do so. Serious personal injury
may result to persons not experi-
enced in servicing vehicles.
. Always use the proper tools and
make certain that they are wellmaintained.
. Never get under the vehicle sup-
ported only by a jack. Always use
safety stands to support thevehicle.
. Never keep the engine running in
a poorly ventilated area, such as
a garage or other closed areas.
. Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire.
. Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only
by your SUBARU dealer.
. Wear adequate eye protection to Maintenance and service

11-4Maintenance and service
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.
. Do not tamper with the wiring of
the SRS airbag system or seat-
belt pretensioner system, or at-
tempt to take its connectors
apart, as that may activate the
system or it can render it inop-
erative. NEVER use a circuit
tester for this wiring.
If your SRS airbag or seatbelt
pretensioner needs service, con-
sult your nearest SUBARU deal-
er. &
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 is 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.
. Before performing any servicing
on a vehicle equipped with a
remote engine start system (a
dealer option) temporarily place
that system in the service mode
to prevent it from unexpectedly
starting the engine. &
When checking or servicing
in the engine compartment
CAUTION
Do not contact the belt cover while
checking the components in the
engine compartment. Doing so may
cause your hand to slip off the belt
cover and result in an unexpected
injury.
