2011 SUBARU IMPREZA WRX four wheel drive

Ignition switch
WARNING
. Never turn the ignition switch to
“ LOCK ”while the vehicle is
being driven or towed because
that will lock the steering wheel,
preventing steering control. And
when the engine is turned off, it
takes a much greater effort than
usual to steer.
. Before leaving the vehicle, al-
ways remove the key from the
ignition switch for safety and
never allow an unattended child
to remain in the vehicle. Failure
to follow this procedure could
result in injury to a child or
others. Children could operate
the power windows, the moon-
roof or other controls or even
make the vehicle move.
CAUTION
Do not attach a large key holder or
key case to either key. If it banged
against your knees or hands while
you are driving, it could turn the
ignition switch from the “ON ”posi- tion to the
“Acc ”or “LOCK ”posi-
tion, thereby stopping the engine.
Also, if the key is attached to a
keyholder or to a large bunch of
other keys, centrifugal force may act
on it as the vehicle moves, resulting
in unwanted turning of the ignitionswitch.
The ignition switch has four positions:
LOCK, Acc, ON and START. NOTE . Keep the ignition switch in the
“ LOCK ”position when the engine is
not running. . Using electrical accessories for a
long time with the ignition switch in the“ ON ”or “Acc ”position can cause the battery to go dead..
If the ignition switch will not move
from the “LOCK ”position to the “Acc ”
position, turn the steering wheel
slightly to the left and right as you turn
the ignition switch. & LOCK
The key can only be inserted or removed
in this position. The ignition switch will lock
the steering wheel when you remove the
key.
If turning the key is difficult, turn the
steering wheel slightly to the right and left
as you turn the key. ! AT models

the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of re-
placement or alternate tires or wheels on
the vehicle that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.
Should the warning light illuminate stea-
dily after blinking for approximately one
minute, have the system inspected by
your nearest SUBARU dealer as soon aspossible.
WARNING
If this light does not illuminate
briefly after the ignition switch is
turned ON or the light illuminates
steadily after blinking for approxi-
mately one minute, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as soon as possible.
If this light illuminates while driving,
never brake suddenly and keep
driving straight ahead while gradu-
ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving
serious vehicle damage and serious
personal injury could occur.
If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, replace it with a spare tire
as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the Low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting.
If the light illuminates steadily after
blinking for approximately one min-
ute, promptly contact a SUBARU
dealer to have the system inspected.
CAUTION
The tire pressure monitoring system
is NOT a substitute for manually
checking tire pressure. The tire
pressure should be checked peri-
odically (at least monthly) using a
tire gauge. After any change to tire
pressure(s), the tire pressure mon-
itoring system will not re-check tire
inflation pressures until the vehicle
is first driven more than 20 mph (32
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 20 mph (32 km/h) to start the
TPMS re-checking of the tire infla-
tion pressures. If the tire pressures
are now above the severe low
pressure threshold, the low tire
pressure warning light should turn
off a few minutes later. Therefore, be
sure to install the specified size for
the front and rear tires.

spilled fuel is not covered under
the SUBARU Limited Warranty.
. Always use a genuine SUBARU
fuel filler cap. If you use the
wrong cap, it may not fit or have
proper venting and your fuel tank
and emission control system
may be damaged. It could also
lead to fuel spillage and a fire.
. Immediately put fuel in the tank
whenever the low fuel warning
light illuminates. Engine misfires
as a result of an empty tank
could cause damage to the en-gine. State emission testing (U.S. only)
At state inspection time, remember to
tell your inspection or service station in
advance not to place your SUBARU
AWD vehicle on a two-wheel dynam-
ometer. Otherwise, serious transmis-
sion damage will result.
Some states have started using dynam-
ometers in their state inspection programs
in order to meet their obligation under
federal law to implement stricter vehicle
emission standards to reduce air pollution
from vehicles. A dynamometer is a tread-
mill or roller-like testing device that allows
your vehicle
’s wheels to turn while the
vehicle remains in one place. Depending
on the severity of a state ’s air pollution
problems, the states must adopt either a“ basic ”or “enhanced ”vehicle emission
inspection test. Normally, a portion of the
basic emission test consists of an emis-
sion inspector inserting an analyzer probe
into the exhaust pipe of an idling vehicle
for a short period of time. States with more
severe air pollution problems are required
to adopt an enhanced vehicle emission
test. This test simulates actual driving
conditions on a dynamometer and permits
more accurate measurement of tailpipe
emitted pollution than the basic emission test.
The U.S. Environmental Protection
Agency (EPA) and states using two-wheel
dynamometers in their emission testing
programs have
EXEMPTEDSUBARU
AWD vehicles from the portion of the
testing program that involves a two-wheel
dynamometer.
There are some states that use four-wheel
dynamometers in their testing programs.
When properly used, that equipment will
not damage a SUBARU AWD vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
WARNING
Testing of an All-Wheel Drive model
must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in
uncontrolled vehicle movement and
may cause an accident or injuries to
persons nearby. Starting and operating

“R ” position or vice versa until
the vehicle has completely
stopped. Such shifting may
cause damage to the transmis-sion.
. When parking the vehicle, first
securely apply the parking brake
and then place the select lever inthe “P ” position. Avoid parking
for a long time with the select
lever in any other position as
doing so could result in a dead
battery.
NOTE . When the engine coolant tempera-
ture is still low, the automatic transmis-
sion will upshift to higher engine
speeds than when the coolant tempera-
ture is sufficiently high in order to
shorten the warm-up time and improve
driveability. The gearshift timing will
automatically shift to the normal timing
after the engine has warmed up.. Immediately after ATF (automatic
transmission fluid) is replaced, you
may feel that the automatic transmis-
sion operation is somewhat unusual.
This results from invalidation of data
which the on-board computer has
collected and stored in memory to allow the transmission to shift at the
most appropriate times for the current
condition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.
& Select lever
: Shifting is possible with the brake pedal
depressed.
: Shifting is possible whether the brakepedal is depressed or not. However,
while the ignition switch is in the “LOCK ”
or “Acc ”position, shifting is not possible
if the brake pedal is not depressed.
Depress the brake pedal and move the
select lever.
: Shifting is possible whether the brake pedal is depressed or not.
The select lever has four positions, “P ”,
“ R ”, “N ”, “D ”and also has manual gate for using
“SPORT ”mode or manual mode.
! P (Park)
This position is for parking the vehicle and
starting the engine.
In this position, the transmission is me-
chanically locked to prevent the vehicle
from rolling freely.
When you park the vehicle, first set the
parking brake fully, then shift into the “P ”
position. Do not hold the vehicle with only
the transmission.
To shift the select lever from the “P ”to any
other position, you should depress the
brake pedal fully then move the select
lever. This prevents the vehicle from
lurching when it is started. ! R (Reverse)
This position is for backing the vehicle.
To shift from the “N ”to “R ”position, stop
the vehicle completely then move the
lever to the “R ”position.
! N (Neutral)
This position is for restarting a stalledengine.
In this position the wheels and transmis-
sion are not locked. In this position, the
transmission is neutral; the vehicle will roll
freely, even on the slightest incline unless Starting and operating

that full vehicle control will be
maintained at all times and under
all conditions, its activation
should be seen as a sign that
the speed of the vehicle should
be reduced considerably.
. Whenever suspension compo-
nents, steering components, or
an axle are removed from a
vehicle, have an inspection of
that system performed by an
authorized SUBARU dealer.
. The following precautions should
be observed in order to ensure
that the Vehicle Dynamics Con-
trol system is operating properly: – All four wheels should be
fitted with tires of the same
size, type, and brand. Further-
more, the amount of wear
should be the same for all
four tires.
– Keep the tire pressure at the
proper level as shown on the
vehicle placard attached to
the driver ’s side door pillar.
– Use only the specified tem-
porary spare tire to replace a
flat tire. With a temporary
spare tire, the effectiveness
of the Vehicle Dynamics Con- trol system is reduced and
this should be taken into ac-
count when driving the vehi-
cle in such a condition.
. If non-matching tires are used,
the Vehicle Dynamics Control
system may not operate cor-
rectly.
. The Vehicle Dynamics Control
system helps prevent unstable
vehicle motion such as skidding
using control of the brakes and
engine power. Do not turn off the
Vehicle Dynamics Control sys-
tem unless it is absolutely ne-
cessary. If you must turn off the
Vehicle Dynamics Control sys-
tem, drive very carefully based
on the road surface 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 indicated 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 indicated by
flashing of the Vehicle Dynamics Control
operation indicator light.
NOTE . The Vehicle Dynamics Control sys-
tem may be considered normal when
the following conditions occur.
–Slight twitching of the brake
pedal is felt. – The vehicle or steering wheel
shakes to a small degree.– An operating sound from the
engine compartment is heard
briefly when starting the engine
and when driving off after starting
the engine. – The brake pedal seems to jolt
when driving off after starting the engine.
. In the circumstances listed in the
following, the vehicle may be more
unstable than it feels to the driver. Starting and operating

The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 20 mph (32 km/h). Also,
this system may not react immediately to a
sudden drop in tire pressure (for example,
a blow-out caused by running over a
sharp object).
WARNING
If the low tire pressure warning light
illuminates while driving, never
brake suddenly and keep driving
straight ahead while gradually redu-
cing speed. Then slowly pull off the
road to a safe place. Otherwise an
accident involving serious vehicle
damage and serious personal injury
could occur.
Check the pressure for all four tires
and adjust the pressure to the COLD
tire pressure shown on the tire
placard on the door pillar on thedriver ’s side.
Even when the vehicle is driven a
very short distance, the tires get
warm and their pressures increase accordingly. Be sure to let the tires
cool thoroughly before adjusting
their pressures to the standard
values shown on the tire placard.
Refer to
“Tires and wheels ”F 11-31.
The tire pressure monitoring system
does not function when the vehicle
is stationary. After adjusting the tire
pressures, increase the vehicle
speed to at least 20 mph (32 km/h)
to start the TPMS re-checking of the
tire inflation pressures. If the tire
pressures are now above the severe
low pressure threshold, the low tire
pressure warning light should turn
off a few minutes later.
If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, replace it with a spare tire
as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting.
Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction of
the tire pressure sensors. If the light
illuminates steadily after blinking for
approximately one minute, promptly
contact a SUBARU dealer to have
the system inspected.CAUTION
. Do not place metal film or any
metal parts in the cargo area/
trunk. This may cause poor re-
ception of the signals from the
tire pressure sensors, and the
tire pressure monitoring system
will not function properly.
. FCC WARNING
Changes or modifications not
expressly approved by the party
responsible for compliance
could void the user ’s authority

Driving tips for AWD models
All-Wheel Drive distributes the engine
power to all four wheels. AWD models
provide better traction when driving on
slippery, wet or snow-covered roads and
when moving out of mud, dirt and sand.
By shifting power between the front and
rear wheels, SUBARU AWD can also
provide added traction during acceleration
and added engine braking force duringdeceleration.
Therefore, your SUBARU AWD vehicle
may handle differently than an ordinary
two wheel drive vehicle and it contains
some features unique to AWD. For safety
purposes as well as to avoid damaging
the AWD system, you should keep the
following tips in mind..
An AWD model is better able to climb
steeper roads under snowy or slippery
conditions than a two wheel drive vehicle.
There is little difference in handling,
however, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an
ample distance from other vehicles. . When replacing a tire, make sure you
use only the same size, construction,
brand, and load range as the original tires
listed on the tire placard. Using other
sizes, circumference or construction may
result in severe mechanical damage to the
drive train of your vehicle and may affect
ride, handling, braking, speedometer/od-
ometer calibration, and clearance be-
tween the body and tires. It also may be
dangerous and lead to loss of vehiclecontrol. . 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. .
There are some precautions that you
must observe when towing your vehicle.
For detailed information, refer to “Towing ”
F 9-14.
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 model could easily
lead to a serious accident. Driving tips

that are of the same size, con-
struction, brand, and load range.
Mixing other sizes or construc-
tions may result in severe me-
chanical damage to the drive
train of your vehicle and may
affect ride, handling, braking and
speedometer/odometer calibra-
tion. It also may be dangerous
and lead to loss of vehicle con-trol.
. Do not use a combination of
radial, belted bias or bias tires
since it may cause dangerous
handling characteristics and lead
to an accident.
! Turbo models
Your vehicle is equipped with “summer
tires ”as original equipment, which are
inadequate for driving on slippery roads
such as on snow-covered or icy roads.
Compared with winter and all-season
tires, summer tires give significantly less
grip on snowy and icy road surfaces.
Therefore, use of winter tires is strongly
recommended when driving with such
road conditions.
When you choose to install winter tires on
your vehicle, be sure to use the correct tire
size and type. You must install four winter tires that are of the same size, construc-
tion, brand and load range and you should
never mix radial, belted bias or bias tires
since this may result in dangerous hand-
ling characteristics. When you choose a
tire, make sure that there is enough
clearance between the tire and vehicle
body.
Remember to drive with care at all times
regardless of the type of tires on yourvehicle. !
Non-turbo models
Your vehicle is equipped with “all season
tires ”as original equipment, which are
designed to provide an adequate measure
of traction, handling and braking perfor-
mance in year-round driving. In winter, it
may be possible to enhance performance
through use of tires designed specifically
for winter driving conditions.
When you choose to install winter tires on
your vehicle, be sure to use the correct tire
size and type. You must install four winter
tires that are of the same size, construc-
tion, brand and load range and you should
never mix radial, belted bias or bias tires
since this may result in dangerous hand-
ling characteristics. When you choose a
tire, make sure that there is enough
clearance between the tire and vehicle
body. Remember to drive with care at all times
regardless of the type of tires on yourvehicle.
& Tire chains
CAUTION
Tire chains cannot be used on your
Impreza, WRX and STI because of
the lack of clearance between the
tires and vehicle body.
& Rocking the vehicle
If you must rock the vehicle to free it from
snow, sand, or mud, depress the accel-
erator pedal slightly and move the shift
lever/select lever back and forth between“ 1 ”/“ 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).
If your vehicle is an AT model, for
information about holding the transmission
in the 2nd position, refer to “Selection of
manual mode ”F 7-26. Driving tips
