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

NOTEContact a SUBARU dealer when jack-
ing up the vehicle using a garage jack.
1. Park on a hard, level surface, when-
ever possible, then stop the engine.
2. Set the parking brake securely and
shift the shift lever in reverse (MT models)
or the select lever to the “P” (Park) posi-
tion (AT models).
3. Turn on the hazard warning flasher
and unload all occupants and luggage
from the vehicle.
4. Put wheel blocks at the front and rear
of the tire diagonally opposite the flat tire. 5. Take out the jack, jack handle and

wheel nut wrench.
The tools and the spare tire are stored
under the floor of the trunk. Refer to
"Maintenance Tools" P302.
NOTEMake sure that the jack is well lubri-
cated before using it.
6. Models with spare tire: Take out the
under-floor storage compartment and turn
the attaching bolt counterclockwise, then
take the spare tire out.
 Always turn off the engine before
raising the flat tire off the ground
using the jack. Never swing or
push the vehicle supported with
the jack. The jack can come out of
the jacking point due to a jolt and
this can result in serious injury or
death. All passengers must exit the
vehicle before you raise it with
the jack. Raising the vehicle with
someone inside of it could result
in serious injury or death. Do not start the vehicle while it is
supported by the jack. Doing so
could result in serious injury or
death.
CAUTION
Do not hit and bend the disc rotor
backing plate when removing and
installing the tire. A bent backing
plate may scrape against the disc
rotor and cause noise while the

tighten the wheel nuts to the specified
torque, following the tightening order in
the illustration.
For the wheel nut tightening torque, refer
to "Tires" P385. Never use your foot on
the wheel nut wrench or a pipe extension
on the wrench because you may exceed
the specified torque. Have the wheel nut
torque checked at the nearest automotive
service facility.

Flat Tires
308Do not use tire chains on a sealed
tire. Do not tow a trailer.If used for a purpose other than
sealing a flat tire, the flat tire
repair kit may cause a severe
accident or injury due to the fact
that compressed air can act as an
explosive or propellant. Safely park your vehicle on the
roadside so that you do not
obstruct the flow of traffic and so
that you are able to seal the flat
tire without being in danger. Apply the parking brake, even if
the vehicle is parked on a level
road, to make sure that the
vehicle will not move. Stop the engine before sealing
the flat tire. Turn on the hazard warning
flasher while sealing the flat tire. Do not attempt to remove foreign
objects like nails or screws that
have penetrated the tire. Leave
them as they are. Never leave the flat tire repair kit
unattended while in use. Only one tire can be repaired with
one bottle of sealant.
 The tires can be repaired when
the ambient temperature is −22 °F
( − 30 °C) or higher.
CAUTION
 Remember that the flat tire repair
kit only provides temporary
mobility. Regulations concerning
tire repair after usage of flat tire
repair kit may di ffer from country
to country. We recommend that
you consult your SUBARU dealer
or tire dealer for advice. Store the flat tire repair kit safely
and secure it under the floor of
the trunk. Storing it anywhere in
the passenger compartment is
not advisable because it could
strike an occupant in the event of
a sudden stop or collision and
cause injury. Use the flat tire repair kit with
original vehicle tires only. Do not keep the air compressor
operating for more than 10
minutes, otherwise there is a risk
of overheating. The temperature of the air
compressor may become high.
Be careful not to burn yourself.
When raining, take measures to
prevent the air compressor from
being exposed directly to the
rain. Exposing to rain may cause
a malfunction. Do not use air compressors other
than the one in the repair kit.
Using an air compressor other
than the one in the repair kit may
damage the tires. Do not disassemble or modify the
air compressor to enable the use
of a power supply or a battery
other than DC 12 V. If a temporary puncture repair is
performed with the repair kit, the
Tire Pressure Monitoring System
(TPMS) (if equipped) may not
operate normally.

places.■Using a Flat-Bed Truck
This is the best way to transport your
vehicle. Use the following procedures to
ensure safe transportation.
1. Shift the select lever into the “P” posi-
tion for AT models. Sh ift the shift lever into
the 1st position for MT models.
2. Apply the parking brake firmly.
3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out.
■ Towing with All Wheels on
the Ground
WARNING
Use the rear tie-down holes only for
downward anchoring. If they are
used to anchor the vehicle in any
other direction, cables may slip out
of the holes, possibly causing a
dangerous situation.
900488
CAUTION
Transport by flat -bed truck may
cause the headlights to become
misaligned. In such a case, have the
headlight alignment checked by a
SUBARU dealer after transporting
the vehicle by flat-bed truck.
WARNING
 Never turn the ignition switch to
the “OFF” position while the
vehicle is being towed because
the steering wheel and the direc-
tion of the wheels will be locked. Remember that the brake booster
and power steering do not func-
tion when the engine is not
running. Because the engine is
turned off, it w ill take greater
effort to operate the brake pedal
