Catalytic Converter
291
Driving Tips8
NOTEDue to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the
exhaust system for a short time after
the engine has been shut off. This
sound is normal.
8-4. Catalytic ConverterThe catalytic converter is installed in the
exhaust system. It serves as catalyst to
reduce HC, CO and NOx in exhaust
gases, thus providing cleaner exhaust. To avoid damage to the catalytic

converter:
 Use only unleaded gasoline. Even a
small amount of leaded gasoline will
damage the catalytic converter.
 Never start the engine by pushing or
pulling the vehicle.
 Avoid racing the engine.
 Never turn off the ig nition switch while
the vehicle is moving.
 Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer.
 Do not apply undercoating or rust
prevention treatment to the heat shield of
catalytic converter and the exhaust
system.
 Do not drive with an extremely low fuel
level.
 If at any time you suspect that
exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open. Keep the trunk lid closed while
driving to prevent exhaust gas
from entering the vehicle.
WARNING
Avoid fire hazards. Do not drive
or park the vehicle anywhere near
flammable materi als (e.g. grass,
paper, rags or leaves), because
the catalytic converter operates
at very high temperatures. Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.

Driving Tips8
– CONTINUED –
Remember to drive with care at all times
regardless of the type of tires on your
vehicle.■ Tire Chains
NOTEWhen tire chains cannot be used, use
of another type of traction device
(such as spring chains) may be
acceptable if use on your vehicle is
recommended by the device manufac-
turer, taking into account tire size and
road conditions. Follow the device
manufacturer’s instructions, espe-
cially regarding maximum vehicle
speed.
To help avoid damage to your vehicle,
drive slowly, readjust or remove the
device if it is contacting your vehicle,
and do not spin your wheels. Damage
caused to your vehicle by use of a
traction device is not covered under
warranty.
Make certain that any traction device
you use is an SAE class S device, and use it on the rear wheels only. Always

use the utmost care when driving with
a traction device. Overconfidence
because you are using a traction
device could easily lead to a serious
accident.
■ Rocking the VehicleIf you must rock the v ehicle to free it from
snow, sand, or mud, depress the acceler-
ator pedal slightly and move the shift
lever/select lever back and forth between
“1” (MT model)/“D” (AT model) and “R”
repeatedly. Do not race the engine. For
the best possible traction, avoid spinning
the wheels when trying to free the vehicle.
When the road surface is extremely slip-
pery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than in 1st (MT models).
If your vehicle is a AT model, Snow mode
can be used. For details about how to use
the mode, refer to "Driving Mode Select
Switch (If Equipped)" P241.
8-9. Loading Your Vehicle
CAUTION
Tire chains cannot be used on your
vehicle because of the lack of clear-
ance between the tires and vehicle
body.
WARNING
Never allow passengers to ride on a
folded rear seatback or in the trunk.
Doing so may result in serious
injury.
WARNING
 Never stack luggage or other
cargo higher than the top of the
seatback because it could tumble
forward and injure passengers in
the event of a sudden stop or
accident. Keep luggage or cargo
low, as close to the floor as
possible.

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
CAUTION
Do not carry spray cans, containers
with flammable or corrosive liquids
or any other dangerous items inside
the vehicle.

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

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.

In Case of Emergency9
– CONTINUED –
1. Release the parking brake and put the
transmission in neutral.
2. The ignition switch should be in the
“ON” position while the vehicle is being
towed.
3. Take up slack in the towline slowly to
prevent damage to the vehicle.
9-7. Access Key Fob – If
Access Key Fob Does Not Operate ProperlyThe following functions may be inoperable
because of strong radio signals in the
surrounding area or a low battery condi-
tion of the access key fob.
 Locking/unlocking doors including

 Switching power status
 Starting engine
In such cases, perform the following
procedure. When t he battery of the
access key fob is discharged, replace it
with a new one. Refer to "Replacing
Battery of Access Key Fob" P376.
CAUTION
 If transmission failure occurs,
transport your vehicle on a flat-
bed truck. Sometime damaged vehicles
cannot be towed because of their
damaged condition. In that case,
use a flat-bed truck for transpor-
tation. The traveling speed must be
limited to less than 20 mph (32
km/h) and the traveling distance
to less than 19 miles (30 km). For
greater speeds and distances,
transport your vehicle on a flat-
bed truck. Use a flat-bed truck if there are
long distance downgrades or
steep slopes. However, do not
apply the brake pedal for a long
time because the engine braking
will not work while towing. Doing
so could overheat the brake. Drive carefully and do not make
an impact on the towing rope by
suddenly starting.
 Use a specific towing rope for
towing. If wire ropes and metal
chains are needed to be used for
towing, wrap the contact portion
of the bumper with cloth to
protect it from damage.
CAUTION
