2009 SUBARU LEGACY check engine

spare tire, the effectiveness of
the Vehicle Dynamics Control
system is reduced and this
should be taken into account
when driving the vehicle in
such a condition.
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system
adjusts the engine ’s output and the
wheels ’respective braking forces to help
maintain traction and directional control. . Traction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown by
steady illumination of the Vehicle Dy-
namics Control operation indicator light. . Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels ’tendency to slide
sideways during steering operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light. NOTE .
Slight twitching of the brake pedal
may be felt when the Vehicle Dynamics
Control system operates; a small de-
gree of vehicle or steering wheel shak-
ing may also be noticed in this situa-
tion. These are normal characteristics
of Vehicle Dynamics Control operation
and are no cause for alarm.. When driving off immediately after
starting the engine, a short-lived opera-
tion noise may be noticed coming from
the engine compartment. This noise is
generated as a result of a check being
performed on the Vehicle Dynamics
Control system and is normal.. Depending on the timing of activa-
tion of the brakes, the brake pedal may
seem to jolt when you drive off after
starting the engine. This is a conse-
quence of the Vehicle Dynamics Con-
trol operational check and is normal.. In the circumstances shown in the
following list, the vehicle may be more
unstable than it feels to the driver. The
Vehicle Dynamics Control System may
therefore operate. Such operation does
not indicate a system fault.
–on gravel-covered or rutted
roads – on unfinished roads
– when the vehicle is towing a trailer–
when the vehicle is fitted with
snow tires or winter tires
. Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheel to feel slightly
different compared to that for normalconditions. . Even if the vehicle is equipped with
a Vehicle Dynamics Control system, it
is important that winter tires be used
when driving on snow-covered or icy
roads. (All four wheels should be fitted
with tires of the same size and brand.)
Furthermore, if snow chains are to be
used, they should be fitted on the front
wheels. When a vehicle is fitted with
snow chains, however, the effective-
ness of the Vehicle Dynamics Control
system is reduced and this should be
taken into account when driving the
vehicle in such a condition. . It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with
Vehicle Dynamics Control. . All four wheels should be fitted with
tires of the same size, type, and brand;
furthermore, the amount of wear
should be the same for all four tires. If
these precautions are not observed
and non-matching tires are used, it is Starting and operating

This single light has the function of
indicating malfunctions in the Vehicle
Dynamics Control system and the function
of indicating that the Vehicle Dynamics
Control system is not operating. It illumi-
nates in the event of a malfunction in the
system and is illuminated whenever the
system is not operating. !Vehicle Dynamics Control warning
The warning light illuminates when the
ignition switch is turned to the “ON ”
position and goes off several seconds
after engine startup. This lighting pattern
indicates that the Vehicle Dynamics Con-
trol system is operating normally.
The following situations could indicate a
malfunction of the Vehicle Dynamics
Control system; if any should occur, have
an authorized SUBARU dealer carry out
an inspection of the system at the first
available opportunity. . The warning light does not turn on
when the ignition switch is turned to the
ON position. . The warning light turns on while the
vehicle is being driven.. When a malfunction has occurred in
the Vehicle Dynamics Control electrical
system, only the warning light will turn on.
In such an event, the ABS will still be
operating normally. .
The warning light will also turn on when
a problem occurs with the ABS or Vehicle
Dynamics Control electronic control sys-tems.
Because the Vehicle Dynamics Control
system controls each brake through the
ABS, whenever the ABS stops operating
due to a malfunction in that electrical
system, the Vehicle Dynamics Control will
also become unable to control all four
brakes. Thus Vehicle Dynamics Control
system operation halts and the warning
light turns on. Although both the Vehicle
Dynamics Control system and the ABS
will be inoperable in this situation, it will
still be possible to stop the vehicle using
normal braking. The Vehicle Dynamics
Control system and the ABS do not
adversely affect operation of the vehicle
in any way when they are inoperable;
however should such a situation occur,
drive with care and have an authorized
SUBARU dealer carry out an inspection of
those systems at the first available oppor-
tunity. NOTE
When the warning light turns on and off
in the following way, it indicates that
the Vehicle Dynamics Control system
is operating normally. . Although turning on after the engine has been started, the warning light
quickly turns off and stays off..
The warning light turns on when the
vehicle is being driven; it then turns off
and stays off. ! Vehicle Dynamics Control OFF in-
dicator light
This light illuminates to indicate that the
Vehicle Dynamics Control system is in
non-operation mode. This does not con-
stitute failure of the Vehicle Dynamics
Control system. NOTE . The indicator light may stay on for a
while after the engine has been started,
especially in cold weather. This occurs
because the engine has not yet
warmed up and is completely normal.
The light will turn off when the engine
has reached a suitable operating tem-perature.. When an engine problem occurs
and the CHECK ENGINE warning light/
malfunction indicator lamp turns on,
the indicator light will also illuminate.
The following two situations could indicate
malfunction of the Vehicle Dynamics
Control system; if either should occur,
have an authorized SUBARU dealer carry
out an inspection of that system at the first Starting and operating

Engine exhaust gas (carbon monoxide)
WARNING
. Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
. Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from enter-
ing the vehicle.
. Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
. Avoid remaining in a parked
vehicle for a lengthy time while
the engine is running. If that is
unavoidable, then use the venti-
lation fan to force fresh air into
the vehicle.
. Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly.
. 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 (Sedan) or rear
gate (Station wagon) closed
while driving to prevent exhaust
gas from entering the vehicle.
NOTE
Due 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 ex-
haust system for a short time after the
engine has been shut off. This sound isnormal. Catalytic converter
WARNING
. Avoid fire hazards. Do not drive
or park the vehicle anywhere
near flammable materials (e.g.
grass, paper, rags or leaves),
because the catalytic converter
operates at very high tempera-tures.
. Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.

The 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 conver-ter: .
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 ignition 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 sys-tem. Periodic inspections
To keep your vehicle in the best condition
at all times, always have the recom-
mended maintenance services listed in
the maintenance schedule in the
“War-
ranty and Maintenance Booklet ”per-
formed at the specified time or mileageintervals.

vehicle and may affect ride, handling,
braking, speedometer/odometer calibra-
tion, and clearance between the body
and tires. It also may be dangerous and
lead to loss of vehicle control. .If you use a temporary spare tire to
replace a flat tire, be sure to use the
original temporary spare tire stored in the
vehicle. Using other sizes may result in
severe mechanical damage to the drive
train of your vehicle. . Always check the cold tire pressure
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, which is located under the
door latch on the driver ’s side.
. Tire chains should always be placed on
the front wheels only. . There are some precautions that you
must observe when towing your vehicle.
For detail information, refer to the “Towing ”
section in chapter 9. Off road driving
WARNING
. Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden brak-
ing or under other similar condi-tions.
. Always use the utmost care in
driving –overconfidence be-
cause you are driving an All-
Wheel Drive vehicle could easily
lead to a serious accident.
& All AWD models except OUTBACK
Your AWD vehicle is neither a conven-
tional off-road vehicle nor an all terrain
vehicle. It is a passenger car designed
primarily for on-road use. The AWD
feature gives it some limited off-road
capabilities in situations in which driving
surfaces a relatively level, obstruction-free
and otherwise similar to on-road driving
conditions. Operating it under other than
those conditions could subject the vehicle
to excessive stress which might result in damage not eligible for repair under
warranty. If you do take your SUBARU
off road, you should review the common
sense precautions in the next section
(applicable to the OUTBACK) for general
guidance. But please keep in mind that
your vehicle
’s off-road capabilities are
more limited than those of the OUTBACK.
Never attempt 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. & OUTBACK
Because of the AWD feature and higher
ground clearance, your SUBARU can be
driven on ordinary roads or off-road. But
please keep in mind that an AWD
SUBARU is a passenger car and is
neither a conventional off-road vehicle
nor an all-terrain vehicle. If you do take
your SUBARU off-road, certain common
sense precautions such as those in the
following list should be taken: . Make certain that you and all of your
passengers are wearing seatbelts. . Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio.

.Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain. . Slow down and employ extra caution at
all times. When driving off-road, you will
not have the benefit of marked traffic
lanes, banked curves, traffic signs and
the like. . Do not drive across steep slopes.
Instead, drive either straight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or
down slopes that are too steep. . Avoid sharp turning maneuvers, espe-
cially at higher speeds. . Do not grip the inside or spokes of the
steering wheel. A bad bump could jerk the
wheel and injure your hands. Instead drive
with your fingers and thumbs on the
outside of the rim. . If driving through water, such as when
crossing shallow streams, first check the
depth of the water and the bottom of the
stream bed for firmness and ensure that
the bed of the stream is flat. Drive slowly
and completely through the stream. The
water should be shallow enough that it
does not reach the vehicle ’s undercar-
riage. 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. Never
attempt to drive through rushing water;
regardless of its depth, it can wash away
the ground from under your tires, resulting
in possible loss of traction and even
vehicle rollover. .
Always check your brakes for effec-
tiveness immediately after driving in sand,
mud or water. Do this by driving slowly
and stepping on the brake pedal. Repeat
that process several times to dry out the
brake discs and brake pads. . Do not drive or park over or near
flammable materials such as dry grass or
fallen leaves, as they may burn easily. The
exhaust system is very hot while the
engine is running and right after engine
stops. This could create a fire hazard. . After driving through tall grass, mud,
rocks, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stones,
sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from
the underbody. If the vehicle is used with
these materials trapped or adhering to the
underbody, a mechanical breakdown or
fire could occur. . Secure all cargo carried inside the
vehicle and make certain that it is not
piled higher than the seatbacks. During
sudden stops or jolts, unsecured cargo
could be thrown around in the vehicle and cause injury. Do not pile heavy loads on
the roof. Those loads raise the vehicle
’s
center of gravity and make it more prone
to tip over. . If you must rock the vehicle to free it
from sand or mud, depress the accelerator
pedal slightly and move the selector lever
back and forth between “D ” 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
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT). . Never equip your vehicle with tires
larger than those specified in this manual.. Wash the vehicle ’s underbody after off-
road driving. Suspension components are
particularly prone to dirt buildup, so they
need to be washed thoroughly. . Frequent driving of an AWD vehicle
under hard-driving conditions such as
rough roads or off roads will necessitate
more frequent replacement of engine oil,
brake fluid and transmission oil than that
specified in the maintenance schedule
described in the “Warranty and Mainte-
nance Booklet ”.

for warranty coverage. Winter driving
&
Operation during cold weather
Carry some emergency equipment, such
as tire chains, a window scraper, a bag of
sand, flares, a small shovel, and jumpercables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winterstarts.
Use an engine oil of proper grade and
viscosity for cold weather. Heavy summer
oil will cause harder starting.
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 after-
wards thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the followingtable.
