“ON”), it could be an indication of leaking of brake fluid or
worn brake pads. Have your vehicle checked by a SUBARU dealer
immediately.
Door open warning lights
The specific 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. Low fuel warning light
The low fuel warning light comes on when the tank is nearly empty about 2.6 U.S. gal. (10.0 liters, or 2.2 Imp. gal.). It only operates when the igni-
tion switch is in the “ON” position.
NOTE This light does not go out unless the tank is replenished up to an internal fuel quantity of about 3.7 U.S. gal. (14 liters, 3.1 Imp. gal.). Front-wheel drive warning light (for AT vehicles except GT and vehicle with VDC)
This light comes on when All Wheel Drive is disengaged and the drive
mechanism is switched to Front Wheel Drive for maintenance or similarpurposes. VDC (Vehicle Dynamics Control) operation indicator light (if equipped)
This light comes on when the ignition switch is ON and goes out about 2
seconds later.
It blinks when the skid suppression function is activated. It illuminates
when only the traction control function is operating.
The VDC system is probably faulty under any of the following conditions.
Have your vehicle checked at a SUBARU dealer immediately. The light does not come on when the ignition switch is turned to the
“ON” position.
The light does not go out even after a period of about 2 seconds after

will automatically downshift to 2nd or 1st gear. When you release the
pedal, the transmission will return to the original gear position.
2 (Second)
This position is for using engine braking when going down a hill or for
climbing a steep grade.
In this position, the transmission holds in the 2nd gear.
Use this position when starting off from a standstill on slippery road
surfaces such as mud or snow. It will ensure greater traction. 1 (First)
This position is for driving up or down very steep grades, or driving
through mud or sand, or on slippery surfaces. In this position, the
transmission holds in the 1st gear. Maximum speeds
WARNING
When shifting down a gear, ensure that the vehicle is not travel- ling at a speed exceeding the Maximum Allowable Speed for thegear which is about to be selected. Failure to observe this pre-caution can lead to engine over-revving and this in turn canresult in engine damage.In addition, sudden application of engine brakes when the vehicleis travelling on a slippery surface can lead to wheel locking; as a
consequence, control of the vehicle may be lost and the risk ofan accident increased.
The following tables show the maximum speeds that are possible with
each different gear. The tachometer ’s (if so equipped) needle will
enter the red area if these speeds are exceeded.
When shifting down a gear, it is important to confirm that the current
vehicle speed is not in excess of the Maximum Allowable Speed ofthe gear which is about to be selected.
Exceeding the Maximum Allowable Speeds will result in over-revving
of the engine. In addition a powerful engine brake will engage and
control of the vehicle may be lost.

In the event of wheelspin and/or skidding on a slippery road surface
and/or during cornering and/or an evasive maneuver, the VDC systemadjusts 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 bysteady illumination of the VDC 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 dur-
ing steering operations. Activation of this function is shown by flash-ing of the VDC operation indicator light.
NOTE Slight twitching of the brake pedal may be felt when the VDC-sys-
tem operates; a small degree of vehicle or steering wheel shaking may also be noticed in this situation. These are normal characteris-tics of VDC operation and are no cause for alarm. When driving off immediately after starting the engine, a short-
lived operation noise may be noticed coming from the enginecompartment. This noise is generated as a result of a check beingperformed on the VDC system and is normal. Depending on the timing of activation of the brakes, certain situa-
tions may occur just after driving off where the brake pedal seemsto exhibit a jolting motion. This too is a consequence of the VDCoperational check and is normal. In the circumstances listed below, the vehicle may be more un-
stable than it feels to the driver. The Vehicle Dynamics Control Sys-
tem may therefore operate. Such operation does not indicate a sys-tem fault. on gravel-covered or rutted roads

NOTE
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 nor-
mal. The light will turn off when the engine has reached a suitableoperating temperature. When an engine problem occurs and the CHECK ENGINE
warning light turns on, the VDC OFF indicator light will also turnon. The following two situations could indicate malfunction of the VDC
system; if either should occur, have an authorized SUBARU dealer
carry out an inspection of that system at the first available opportunity. The VDC OFF indicator light does not turn on when the ignition key
is turned to the ON position. 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. n VDC operation indicator light
The VDC operation indicator light turns on when the ignition key is
turned to the ON position; it turns off approximately two seconds later.
This indicator light flashes during activation of the skid suppression
function and is illuminated steadily during activation of the traction
control function. The following two situations could indicate a malfunction of the VDC
system; if either should occur, have an authorized SUBARU dealer
carry out an inspection of that system at the first available opportunity. The VDC operation indicator light does not turn on when the igni-
tion key is turned to the ON position. The VDC operation indicator light does not turn off approximately
two seconds after the ignition key has been turned to the ON position. n VDC warning light
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.

WARNING
When replacing original tires with winter (snow) tires, make
sure you use only the same size, construction and load range as the original tires listed on the tire placard. Using other sizes andconstruction may affect speedometer/odometer calibration and
clearance between the body and tires. It also may be dangerousand lead to loss of vehicle control. You must install four winter tires that are of the same size, cir-
cumferences, construction, brand, and load range. Mixing othersizes, circumferences or constructions may result in severe me-
chanical damage to the drive train of your vehicle and may affect
ride, handling, braking and speedometer/odometer calibration. Italso may be dangerous and lead to loss of vehicle control. Do not use a combination of radial, belted bias or bias tires
since it may cause dangerous handling characteristics and leadto an accident.
Your vehicle is equipped with “all season tires ” which are designed to
provide an adequate measure of traction, handling and braking per-
formance in year-round driving. In winter, it may be possible to en-
hance performance through use of tires designed specifically for win-ter driving conditions.
If 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 ofthe same size, construction, brand and load range and you should
never mix radial, belted bias or bias tires since this may result in dan-
gerous handling 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 your vehicle.

The following information has been compiled according to Code of Fed-eral Regulations
“Title 49, Part 575 ”.
Uniform tire quality grading standards
This information indicates the relative performance of passenger car tires
in the area of treadwear, traction, and temperature resistance. This is to
aid the consumer in making an informed choice in the purchase of tires.
Quality grades can be found where applicable on the tire sidewall be-
tween tread shoulder and maximum section width. For example:
Treadwear 200 Traction AA Temperature A
The quality grades apply to new pneumatic tires for use on passenger
cars. However, they do not apply to deep tread, winter type snow tires,
space-saver or temporary use spare tires, tires with nominal rim diame-
ters of 12 inches or less, or to some limited production tires.
All passenger car tires must confirm to Federal Safety Requirements in
addition to these grades. Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified govern-
ment test course.
For example, a tire graded 150 would wear one and one-half (1-1/2)
times as well on the government course as a tire graded 100. The rela-
tive performance of tires depends upon the actual conditions of their
use, however, and may depart significantly from the norm due to varia-
tions in driving habits, service practices and differences in road charac-teristics and climate. Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C. Those
grades represent the tire ’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of as-

phalt and concrete. A tire marked C may have poor traction perfor- mance.
WARNING
The traction grade assigned to this tire is based on straight-
ahead braking traction tests, and does not include acceleration,cornering, hydroplaning, or peak traction characteristics.
Temperature A, B, C
The temperature grades are A (the highest), B, and C, representing the
tire’ s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure. The grade C corresponds to a level of perfor-
mance which all passenger car tires must meet under the Federal Motor
Vehicle Safety Standards No. 109. Grades B and A represent higher lev-
els of performance on the laboratory test wheel than the minimum re-
quired by law.
WARNING
The temperature grade for this tire is established for a tire that isproperly inflated and not overloaded. Excessive speed, under-inflation, or excessive loading, either separately or in combina-tion, can cause heat buildup and possible tire failure.
