yThis light turns on to indicate that the VDC system
is in non-operation mode. This does not constitute fail- ure of the VDC system.
NOTE y The VDC OFF 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 temperature. y When an engine problem occurs and the CHECK
ENGINE warning light turns on, the VDC OFF indi-
cator light will also turn on.
The following two situations could indicate malfunction
of the VDC system; if either should occur, have an au-
thorized SUBARU dealer carry out an inspection of
that system at the first available opportunity. y The VDC OFF indicator light does not turn on when
the ignition key is turned to the ON position. y The VDC OFF indicator light fails to turn off after the
engine is started, even when several minutes have
passed to allow the engine to heat up sufficiently. T VDC operation indicator light
The VDC operation indicator light turns on when the
ignition key is turned to the ON position; it turns off ap- proximately two seconds later. This indicator light
flashes during activation of the skid suppression func-
tion and is illuminated steadily during activation of the
traction control function.
The following two situations could indicate a malfunc-
tion of the VDC system; if either should occur, have an

The VDC warning light turns on when the ignition key
is turned to the ON position and off when the engine is
started. This lighting pattern indicates that the VDC
system is operating normally.
The following situations could indicate a malfunction of
the VDC system; if any should occur, have an autho-

Snow tires
T All models except OUTBACK
yWhen replacing original tires with winter
(snow) tires, make sure you use only the same
size, construction and load range as the origi-
nal tires listed on the tire placard. Using other
sizes and construction may affect speedome-
ter/odometer calibration and clearance be-
tween the body and tires. It also may be danger-
ous and lead to loss of vehicle control. y You must install four winter tires that are of
the same size, circumferences, construction,
brand, and load range. Mixing other sizes, cir-
cumferences or constructions may result in se-
vere mechanical 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 control. y Do not use a combination of radial, belted
bias or bias tires since it may cause dangerous
handling characteristics and lead to an acci-
dent. Your vehicle is equipped with “all season tires” which
are designed to provide an adequate measure of trac-
tion, handling and braking performance in year-round
driving. In winter, it may be possible to enhance per-
formance through use of tires designed specifically for
winter driving conditions.
If you choose to install winter tires on your vehicle, be
sure to use the correct tire size and type. You must in-
stall four winter tires that are of the same size, con-
struction, brand and load range and you should never
mix radial, belted bias or bias tires since this may re-
sult in dangerous handling characteristics. When you
choose a tire, make sure that there is enough clear-
ance between the tire and vehicle body.
Remember to drive with care at all times regardless of
the type of tires on your vehicle. T

Your OUTBACK comes with P225/60R16 “all sea-
son tires” as original equipment. You should be
aware that some winter tires with that same size
designation may actually be too large for the vehi-
cle and may cause rubbing on sharp turns. Listed
below is the winter tire size that we recommend.Recommended winter (snow) tire size

Spark plugs
yWhen disconnecting the spark plug cables,
always grasp the spark plug cap, not the ca-
bles. y Make sure the cables are replaced in the cor-
rect order.
It may be difficult to replace the spark plugs. It is rec-
ommended that you have the spark plugs replaced by
your SUBARU dealer. The spark plugs should be replaced according to the
maintenance schedule in the “Warranty and Mainte-
nance Booklet”. „

„Headlight
Halogen headlight bulbs become very hot while
in use. If you touch the bulb surface with bare
hands or greasy gloves, finger prints or grease
on the bulb surface will develop into hot spots
and cause the bulb to break. If there are finger
prints or grease on the bulb surface, wipe them
away with a soft cloth moistened with alcohol.
NOTE
If headlight aiming is required, consult your
SUBARU dealer for proper adjustment of the head-
light aim. T

Consumer information and Reporting safety defects

hicle control could lead to an accident. TMeasuring and adjusting air pressure to
achieve proper inflation
Check and, if necessary, adjust the pressure of
each tire (including the spare) at least once a
month and before any long journey. Check the
tire pressures when the tires are cold. Use a
pressure gauge to adjust the tire pressures to the
specific values. Driving even a short distance
warms up the tires and increases the tire pres-
sures. Also, the tire pressures are affected by the
ambient temperature. It is best to check tire pres-
sure outdoors before driving the vehicle. When a
tire becomes warm, the air inside it expands,
causing the tire pressure to increase. Be careful
not to mistakenly release air from a warm tire to
reduce its pressure. „ Glossary of tire terminology
y Cold tire pressure
The pressure in a tire that has been driven less
than 1 mile or has been standing for three hours
or more. y Maximum inflation pressure The maximum cold inflation pressure to which a
tire may be inflated. y
Recommended inflation pressure
The cold inflation pressure recommended by a
vehicle manufacturer. y Intended outboard sidewall
1)The sidewall that contains a whitewall, bears
white lettering or bears manufacturer, brand,
and/or model name molding that is higher or
deeper than the same molding on the other
sidewall of the tire, or
2)The outward facing sidewall of an asymmet-
rical tire that has a particular side that must al-
ways face outward when mounting on a vehi- cle.
y Accessory weight
The combined weight (in excess of those stan-
dard items which may be replaced) of floor mats,
leather seats and cross bars to the extent that
these items are available as factory-installed
equipment (whether installed or not). y Curb weight
The weight of a motor vehicle with standard
equipment including the maximum capacity of fu-
el, oil, and coolant and air conditioning.
