6. If the brake fluid level is below the “MIN” mark, DO
NOT drive the vehicle. Instead, have the vehicle towed
to the nearest SUBARU dealer for repair. „
Door open warning light
The door open warning light comes on if any door or
the rear gate is not fully closed.
Always make sure this light is out before you start to
drive. „ All-wheel drive warning light
(for AWD AT vehicles – if
equipped)
The all-wheel drive warning light comes on when the
ignition switch is turned to the “ON” position and goes
out after about two seconds.
This light comes on when All Wheel Drive is disen-
gaged and the drive mechanism is switched to Front
Wheel Drive for maintenance or similar purposes
(Non-turbo vehicles).
It flashes if the vehicle is driven with tires of differing
diameters fitted on the wheels or with an excessively
low air pressure in any of the tires.
Continuing to drive with the AWD warning light
flashing can damage the powertrain. If the AWD
warning light starts to flash, promptly park in a
safe place and check whether the tires have dif-
fering diameters and whether any of the tires
has an excessively low inflation pressure.
„ Intercooler water spray warning
l i g h t ( W R X - S T i )
This light comes on when the water level in the inter-
cooler water spray tank falls to the lower limit (about
0.4 US qt, 0.4 liter, 0.4 Imp qt).

In case of emergency
– CONTINUED –
Temporary spare tire
The temporary spare tire is smaller and lighter than a
conventional tire and is designed for emergency use
only. Remove the temporary spare tire and re-install
the conventional tire as soon as possible because the
spare tire is designed only for temporary use.
Check the inflation pressure of the temporary spare
tire periodically to keep the tire ready for use. The cor-
rect pressure is 60 psi (420 kPa, 4.2 kg/cm 2
).
When using the temporary spare tire, note the follow-
ing: y Do not exceed 50 mph (80 km/h).
y Do not put a tire chain on the temporary spare tire.
Because of the smaller tire size, a tire chain will not fit
properly. y Do not use two or more temporary spare tires at the
same time. y Do not drive over obstacles. This tire has a smaller
diameter, so road clearance is reduced. 1) Tread wear indicator bar
2) Indicator location mark
y When the wear indicator appears on the tread, re-
place the tire.

Example:
(6) Load Index: A numerical code which speci-
fies the maximum load a tire can carry at the
speed indicated by its speed symbol, at maxi-
mum inflation pressure.
For example, “90” means 1,323 lbs (600 kg), “89”
means 1,278 lbs (580 kg).
Load indices apply only to the tire, not to
the vehicle. Putting a load rated tire on any
vehicle does not mean the vehicle can be
loaded up to the tire’s rated load.
(7) Speed Rating: An alphabetical system de-
scribing a tire’s capability to travel at established
and predetermined speeds.
For example, “V” means 149 mph (240 km/h)
y Speed ratings apply only to the tire, not
to the vehicle. Putting a speed rated tire on
any vehicle does not mean the vehicle can
be operated at the tire’s rated speed. y The speed rating is void if the tires are
worn out, damaged, repaired, retreaded, or
otherwise altered from their original condi-
tion. If tires are repaired, retreaded, or oth-
erwise altered, they may not be suitable for
original equipment tire designed loads and
speeds.
T Tire Identification Number (TIN)
Tire Identification Number (TIN) is marked on the
intended outboard sidewall. The TIN is com-
posed of four groups. Here is a brief review of the
TIN with a breakdown of its individual elements.

(2) Tire Size
(3) Tire Type Code
(4) Date of Manufacture
The first two figures identify the week, starting
with “01” to represent the first full week of the cal-
endar year; the second two figures represent the
year. For example, 0101 means the 1st week of
2001. T
Other markings
The following makings are also placed on the
sidewall. V Maximum permissible inflation pressure
The maximum cold inflation pressure to which
this tire may be inflated. For example, “300 kpa
(44 PSI) MAX. PRESS” V Maximum load rating
The load rating at the maximum permissible
weight load for this tire. For example, “MAX.
LOAD 580 kg (1279 LBS) @ 300 kpa (44 PSI) MAX. PRESS.”
Maximum load rating applies only to the
tire, not to the vehicle. Putting a load rated
tire on any vehicle does not mean the vehi-
cle can be loaded up to the tire’s rated
load.
V Construction type
Applicable construction of this tire.
For example, “TUBELESS STEEL BELTED RA-
DIAL” V Construction
The generic name of each cord material used in
the plies (both sidewall and tread area) of this
tire.
For example, “PLIES: TREAD 2 STEEL + 2
POLYESTER SIDEWALL 2 POLYESTER” V Uniform Tire Quality Grading (UTQG)
For details, refer to “Uniform tire quality grading
standards” in this chapter.

The vehicle placard shows original tire size, rec-

capacity and loading information. T
Adverse safety consequences of under-in-
flation
Driving at high speeds with excessively low tire
pressures can cause the tires to flex severely
and to rapidly become hot. A sharp increase in
temperature could cause tread separation, and
failure of the tire(s). Possible resulting loss of ve-

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
outside 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.
