WARNING
.Driving with the brake system
warning light illuminated is dan-
gerous. This indicates your brake
system may not be working prop-
erly. If the light remains illumi-
nated, have the brakes inspected
by a SUBARU dealer immedi-
ately.
.If at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair.
Vehicle Dynamics Control
system
WARNING
Always use the utmost care in driv-
ing–overconfidence because you
are driving a vehicle with the Vehicle
Dynamics Control system could ea-
sily lead to a serious accident.
CAUTION
.Even if your vehicle is equipped
with Vehicle Dynamics Control
system, winter tires should be
used when driving on snow-cov-
ered or icy roads; in addition,
vehicle speed should be reduced
considerably. Simply having a
Vehicle Dynamics Control sys-
tem does not guarantee that the
vehicle will be able to avoid
accidents in any situation.
.Activation of the Vehicle Dy-
namics Control system is an
indication that the road being
travelled on has a slippery sur-
face; since having Vehicle Dy-
namics Control is no guaranteethat 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.
.Observe the following precau-
tions in order to ensure that the
Vehicle Dynamics Control sys-
tem is operating properly:
–Fit all four wheels with tires of
the same size, type, and
brand. Furthermore, 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 tempor-
ary spare tire to replace a flat
tire. With a temporary 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.
.If you use non-matching tires, the
Vehicle Dynamics Control sys-
tem may not operate correctly.
.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 neces-
sary. If you must turn off the
Vehicle Dynamics Control sys-
tem, drive very carefully accord-
ing to 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 shown byflashing the Vehicle Dynamics 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.
Vehicle Dynamics Control operation indi-
cator lightNOTE.The Vehicle Dynamics Control sys-
tem may be considered normal when
the following conditions occur.
–Slight twitching of the brakepedal 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 shown in the
following list, the vehicle may be less
stable than it feels to the driver. The
Vehicle Dynamics Control System may
therefore operate. Such operation does
not indicate a system malfunction.
–on gravel-covered or rutted roads
–on unfinished roads
–when the vehicle is fitted with
snow tires or winter tires
.Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheelto feel slightly
different compared to that for normal
conditions.
.It is always important to reduce
speed when approaching a corner,
even if your vehicle is equipped with
the Vehicle Dynamics Control system.
.Always turn off the engine before
replacing a tire. Failure to do so may
render the Vehicle Dynamics Control

WARNING
.If the low tire pressure warning
light illuminates while driving,
never brake suddenly. Instead,
perform the following procedure.
Otherwise, an accident involving
serious vehicle damage and ser-
ious personal injury could occur.
(1) Keep driving straight ahead
while gradually reducing
speed.
(2) Slowly pull off the road to a
safe place.
(3) Check the pressure for all four
tires and adjust the pressure
to the COLD tire pressure
shown on the vehicle placard
on the door pillar on the
driver’s side.
Even when the vehicle is driven a
very short distance, the tires get
warm and their pressures in-
crease accordingly. Be sure to
let the tires cool thoroughly be-
fore adjusting their pressures to
the standard values shown on the
tire placard. Refer to“Tires and
wheels”F11-30. The tire pres-
sure monitoring system does not
function when the vehicle is sta-tionary. After adjusting the tire
pressures, increase the vehicle
speed to at least 20 mph (32 km/h)
to start the TPMS rechecking 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 min-
utes later.
If this light still illuminates while
driving after adjusting the tire
pressure, a tire may have signifi-
cant damage and a fast leak that
causes the tire to lose air rapidly.
If you have a flat tire, refer to“Flat
tires”F9-5.
.When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/trans-
mitter being transferred, the low
tire pressure warning light will
illuminate steadily after blinking
for approximately 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 sys-
tem resetting.
.When a tire is repaired with liquid
sealant, the tire pressure warningvalve and transmitter may not
operate properly. If a liquid sea-
lant is used, contact your nearest
SUBARU dealer or other qualified
service shop as soon as possi-
ble. Make sure to replace the tire
pressure warning valve and
transmitter when replacing the
tire. You may reuse the wheel if
there is no damage to it and if the
sealant residue is properly
cleaned off. 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 ap-
proximately one minute,
promptly contact a SUBARU
dealer to have the system in-
spected.
CAUTION
Do not place metal film or any metal
parts in the trunk. This may cause
poor reception of the signals from
the tire pressure sensors, and the
tire pressure monitoring system will
not function properly.

WARNING
.Before exiting the vehicle, make
sure that you turn off the engine.
Otherwise, the parking brake may
be released and an accident may
occur.
.If the brake system warning light
turns on, the electronic parking
brake system may be malfunc-
tioning. Immediately stop yourvehicle in a safe location, use tire
stops under the tires to prevent
the vehicle from moving and
contact your SUBARU dealer.
.If you operate the electronic park-
ing brake when the brake is over-
heated or the vehicle is on a steep
slope, the electronic parking
brake indicator light may flash.
In this case, the vehicle may start
to move and it may lead to an
accident. Always use the tire
stops.
CAUTION
.When the electronic parking
brake system has a malfunction
and the parking brake cannot be
applied, contact your SUBARU
dealer immediately for an inspec-
tion. If you have to park your
vehicle in such conditions, per-
form the following procedure.
–Stop your vehicle in a flat
location.

–Use tire stops under the tires
to prevent the vehicle from
moving.
.Never drive with the parking
brake applied. Doing so will
cause unnecessary wear on the
brake linings. Before driving off,
always make sure that the park-
ing brake has been released and
the brake system warning light
has turned off.
Your vehicle is equipped with an electronic
parking brake. You can apply/release the
parking brake by operating the parking
brake switch.
To apply:Depress the brake pedal and
pull up the parking brake switch.
To release:Press the parking brake
switch firmly while the ignition switch is in
the“ON”position and the brake pedal is
depressed.
When the parking brake is applied while
the ignition switch is in the“ON”position,
the electronic parking brake indicator light
and the indicator light on the parking brake
switch illuminate. Refer to“Brake system
warning light”F3-21.
NOTE.If you press the parking brake switch
under the following conditions, the
parking brake will not be released.
–The ignition switch is in the
“ACC”or“LOCK”/“OFF”position.
–You are not depressing the brake
pedal.
.The electronic parking brake system
uses motors to apply the parking brake.
Therefore, operating sounds from the
motors will be heard when applying or
releasing the parking brake. Make sure
that the motor sounds are heard when
applying or releasing the parking
brake.
.If you operate the parking brake
switch under the following conditions,
a chirp will sound and the electronic
parking brake indicator light will flash.
–when the electronic parking
brake system has a malfunction
–when the electronic parking
brake operation is prohibited tem-
porarily
.When you cannot release the park-
ing brake due to, for example, a system
malfunction, contact your SUBARU
dealer and have your SUBARU dealer
release the parking brake.
.If you stop operating the electronicparking brake switch midway or oper-
ate extremely slowly, the system may
detect an error and turn on the brake
system warning light. However, this
does not indicate a malfunction if the
brake system warning light turns off
after operating the switch.
.When the electronic parking brake
has not been used for a long period of
time, the electronic parking brake may
operate automatically after the ignition
switch is turned to the“LOCK”/“OFF”
position. This occurs due to checking
the proper operation of the electronic
parking brake and does not indicate a
malfunction.
.If you cannot release the electronic
parking brake due to the switch mal-
function, refer to the instructions de-
scribed in“Automatic release function
by accelerator pedal”F7-45.
After activating the electronic parking
brake, you may hear a short sound
several minutes after the electronic
parking brake indicator light illumi-
nates as the system confirms proper
engagement. This sound is different
from the apply and release sound.
This can occur:
–If the brakes are extremely hot.
–If the car is parked on a steep
incline.

New vehicle break-in driving–
the first 1,000 miles (1,600 km)The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km):
.Do not race the engine. And do not
allow engine speed to exceed 4,000 rpm
except in an emergency.
.Do not drive at one constant engine or
vehicle speed, either fast or slow.
.Avoid starting suddenly and rapid ac-
celeration, except in an emergency.
.Avoid hard braking, except in an emer-
gency.
The same break-in procedures should be
applied to an overhauled engine, newly
mounted engine or when brake pads or
brake linings are replaced with new ones.
Fuel economy hintsThe following suggestions will help to save
fuel.
.Select the proper gear position for the
speed and road conditions.
.Avoid sudden acceleration or decelera-
tion. Always accelerate gently until you
reach the desired speed. Then try to
maintain that speed for as long as possi-
ble.
.Do not pump the accelerator and avoid
racing the engine.
.Avoid unnecessary engine idling.
.Keep the engine properly tuned.
.Keep the tires inflated to the correct
pressure shown on the tire placard, which
is located under the door latch on the
driver’s side. Low pressure will increase
tire wear and fuel consumption.
.Use the air conditioner only when
necessary.
.Keep the front and rear wheels in
proper alignment.
.Avoid carrying unnecessary luggage or
cargo.
.The indication of the ECO gauge shows
a reference for saving fuel. For details,
refer to“ECO gauge”F3-12.
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 entering
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 ve-
hicle for a lengthy time while the
engine is running. If that is un-
avoidable, then use the ventila-
tion 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
