Electronic Brake Force Distribution (EBD) System
246The ABS prevents the lock-up of wheels
which may occur during sudden braking or
braking on slippery road surfaces. This
helps prevent the loss of steering control
and directional stability caused by wheel
lock-up.
When the ABS is operating, you may hear
a chattering noise or feel a slight vibration
in the brake pedal. This is normal when
the ABS operates.■
ABS Self-Check
You may feel a slight shock in the brake
pedal and hear the operating noise of the
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
being carried out and does not indicate
any abnormal condition.■
ABS Warning Light
Refer to "ABS Warning Light" P140.
7-12. Electronic Brake Force Distribution (EBD) SystemThe EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of
the braking force. It functions by adjusting
the distribution of braking force to the rear
wheels in accordance with the vehicle’s
loading condition and speed.
The EBD system is an integral part of the
ABS and uses some of the ABS compo-
nents to perform its function of optimizing
the distribution of braking force. If any of
the ABS components used by the EBD
function fails, the EBD system also stops
working.
When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction.
■
EBD System Malfunctions
If a malfunction occurs in the EBD system,
the system stops working and the
following warning lights illuminate simulta-
neously.
 Brake system warning light
 ABS warning light
 Vehicle Stability Control (VSC)
warning light
If the both warning light remains on even
though the parking brake is released, the
brake fluid level may be low or there could
be a problem with the EBD system. Park
the vehicle in a safe place immediately
and contact an SUBARU dealer.
 When you feel the ABS operating,
you should maintain constant
brake pedal pressure. Do not
pump the brake pedal since doing
so may defeat the operation of the
ABS.

until the low tire pressure warning light
blinks slowly 3 times.■
If You Press the Tire Pres-
sure Monitoring Reset
Switch Accidentally
If initialization is performed, adjust the tire
inflation pressure to the specified level
and initialize the tire pressure monitoring
system again.■
Initialization Procedure
 Make sure to carry out initialization
after adjusting the tire inflation pressure.
Also, make sure the tires are cold before
carrying out initialization or tire inflation
pressure adjustment.
 If you have accidentally turned the igni-
tion switch to the “OFF” position during
initialization, it is not necessary to press
the TPMS set switch again as initialization
will restart automatically when the engine
is restarted.
 If you accidentally press the TPMS set
switch when initializa tion is not necessary,
adjust the tire inflation pressure to the
specified level when the tires are cold, and
conduct initialization again.
■
When Initialization of the Tire
Pressure Monitoring System
has Failed
Initialization can be completed in a few
minutes. However, in the following case,
the settings have not been recorded and
the system will not operate properly. If
repeated attempts to record tire inflation
pressure settings are unsuccessful, have
the vehicle checked at your SUBARU
dealer.
 When operating the TPMS set switch,
low tire pressure warning light does not
blink 3 times.
 After carrying out the initialization
procedure, the low tire pressure warning
light blinks for 1 minute then stays on after
driving for 20 minutes.
■
Registering ID Codes
Every tire pressure warning valve and
transmitter has a unique ID code. In addi-
tion to the set of tire pressure warning
system sensor ID code s initially registered
to the vehicle, a second set of ID codes
can be registered.
A second set of tire pressure warning
system sensor ID codes can be registered
at your SUBARU dealer. When 2 sets of
ID codes have been registered, either ID
code set can be selected.■
Changing the ID code set
1. Park the vehicle in a safe place and
turn the ignition switch to the “ON” posi-
tion.
2. Press the TPMS set switch 3 times
within 3 seconds.
3. The low tire pressure warning light will
illuminate for 3 seconds and then blink 3
times.
4. The low tire pressure warning light will
blink for 1 minute and then illuminate.
5. When the ID code change has
completed, the tire pressure monitoring
light will turn off.
Check that tire pressures are displayed on
the TPMS screen.
WARNING
Do not operate the TPMS set switch
without first adjusting the tire infla-
tion pressure to the specified level.
Otherwise, the low tire pressure
warning light may not come on even
if the tire inflation pressure is low,
or it may come on when the tire
inflation pressure is actually nor-
mal.

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.

8-8. Winter Driving■
Operation during Cold
Weather
Carry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small shovel and jumper cables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winter
starts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
Keep the door locks from freezing by
squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen, use
hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that
contains an antifr eeze solution. Do not
use engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
If you fill the windshield washer tank with
a fluid with a different concentration from
If all four tires are not the same in
items (a) to (h), serious mechani-
cal damage could be caused to
the drivetrain of the car, and
affect the followings.- Ride- Handling- Braking- Speedometer/Odometer cali-
bration- Clearance between the bodyand the tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
 In a rollover crash, an unbelted
person is significantly more likely
to die than a person wearing a
seat belt. The driver and all your
passengers should fasten their
seatbelts before st arting to drive
in order to minimize the chance of
serious injury or death. Do not make sharp turns or quick
maneuvers unless absolutely
unavoidable. Such actions are
dangerous as you may lose
control, possibly resulting in a
rollover which could cause death
or serious injury.
Whenever strong crosswinds are
present, slow do wn sufficiently to
maintain control of your vehicle. Never to drive through pools and
puddles, or roads flooded with
water. Water entering the engine
air intake or the exhaust pipe or
water splashing onto electrical
parts may damage your vehicle
and may cause it to stall. In this
case, contact your SUBARU
dealer immediat ely. Regardless
of its depth, it can wash away the
ground from under your tires,
resulting in possible loss of trac-
tion and even vehicle rollover.
CAUTION
After driving on gravel roads or
rough roads, check the undercar-
riage of the vehicle body for any
damage, deformation, or paint
removal. If you notice any irregulari-
ties, contact a SUBARU dealer for
an inspection as soon as possible.

Winter Driving
294the one used previously, purge the old
fluid from the piping between the wind-
shield washer tank and washer nozzles by
operating the washer for a certain period
of time. Otherwise, if the concentration of
the fluid remaining in the piping is too low
for the outside temperature, it may freeze
and block the nozzles.▼
Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery and
driving dangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has accu-
mulated under the fenders to avoid
making steering difficult. During severe
winter driving, stop when and where it is
safe to do so and check under the fenders
periodically.
▼Parking in cold weather
CAUTION
 Adjust the washer fluid concen-
tration appropriately for the
outside temperature. If the
concentration is inappropriate,
sprayed washer fluid may freeze
on the windshield and obstruct
your view, and the fluid may
freeze in the windshield washer
tank.State or local regulations on vola-
tile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle’s paint, wiper blades
or washer system.
WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you
park the vehicle in snow with the
engine running.
CAUTION
Do not use the parking brake
when parking for long periods in
cold weather since it could freeze
in that position.When the vehicle is parked in
snow or when it snows, raise the
wiper blades off the glass to
prevent damage to them.Under either of the following
conditions, icing may develop on
the brake system, which could
cause poor braking action.
- When the vehicle has been left
parked after use on roads
heavily covered with snow- When the vehicle has been leftparked during a snowstormCheck for snow or ice buildup on
the suspension, disc brakes and
brake hoses underneath the vehi-
cle. If there is caked snow or ice,
remove it, being careful not to
damage the disc brakes and
brake hoses and ABS harness.

Engine Overheating
319
In Case of Emergency9
9-5. Engine Overheating■
If Steam Is Coming from the
Engine Compartment
Turn off the engine and get everyone
away from the vehicle until it cools down.
■
If No Steam Is Coming from
the Engine Compartment
1. Keep the engine running at idling
speed.
2. Open the hood to ventilate the engine
compartment. Refer to "Engine Hood"
P343.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays in the over-
heated zone, turn off the engine.
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.NOTEFor details about how to check the
coolant level or how to add coolant,
refer to "Eng ine Coolant" 
P349.
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
counterclockwise 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.
WARNING
Never remove the radiator 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 seri-
ously.
CAUTION
If the engine overheats, the engine
speed or the vehicle speed may be
reduced. Stop the vehicle in a safe
place immediately.

324holes, return the plugs to their original
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. Shift 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
and steering wheel.
