and may produce a sulfur exhaust odor or smell.
SUBARU recommends that you try a different brand of
unleaded gasoline having lower sulfur to determine if
the problem is fuel related before returning your vehi-
cle to an authorized dealer for service. The CHECK
ENGINE warning light/Malfunction indicator lamp may
also turn on. If this occurs, return to your authorized
SUBARU dealer for diagnosis. If it is determined that
the condition is caused by the type of fuel used, re-
pairs may not be covered by your warranty. TMMT
Some gasoline contains an octane-enhancing additive
called MMT (Methylcyclopentadienyl Manganese Tri-
carbonyl). If you use such fuels, your emission control
system performance may deteriorate and the CHECK
ENGINE warning light/Malfunction indicator lamp may
turn on. If this happens, return to your authorized
SUBARU Dealer for service. If it is determined that the
condition is caused by the type of fuel used, repairs
may not be covered by your warranty. T Gasoline for cleaner air
Do not let fuel spill on the exterior surfaces of
the vehicle. Fuels containing alcohol may cause paint damage, which is not covered un-
der the SUBARU Limited Warranty.
Your use of gasoline with detergent additives will help
prevent deposits from forming in your engine and fuel
system. This helps keep your engine in tune and your
emission control system working properly, and is a
way of doing your part for cleaner air. If you continu-
ously use a high quality fuel with the proper detergent
and other additives, you should never need to add any
fuel system cleaning agents to your fuel tank.
Many gasolines are now blended with materials called
oxygenates. Use of these fuels can also help keep the
air cleaner. Oxygenated blend fuels, such as MTBE
(Methyl Tertiary Butyl ether) or ethanol (ethyl or grain
alcohol) may be used in your vehicle, but should con-
tain no more than 15% MTBE or 10% ethanol for the
proper operation of your SUBARU.
In addition, some gasoline suppliers are now produc-
ing reformulated gasolines, which are designed to re-
duce vehicle emissions. SUBARU approves the use of reformulated gasoline.
If you are not sure what the fuel contains, you should
ask your service station operators if their gasolines
contain detergents and oxygenates and if they have

Washing
yWhen washing the vehicle, the brakes may
get wet. As a result, the brake stopping dis-
tance will be longer. To dry the brakes, drive the
vehicle at a safe speed while lightly pressing
the brake pedal to heat up the brakes.y Do not wash the engine compartment and ar-
eas adjacent to it. If water enters the engine air
intake, electrical parts or the power steering flu-
id reservoir, it will cause engine trouble or
faulty power steering respectively.
The best way to preserve your vehicle’s beauty is fre-
quent washing. Wash the vehicle at least once a
month to avoid contamination by road grime.
Wash dirt off with a wet sponge and plenty of luke-
warm or cold water. Do not wash the vehicle with hot
water and in direct sunlight.
Salt, chemicals, insects, tar, soot and bird droppings
should be washed off by using a light detergent, as re- quired. If you use a light detergent, make certain that
it is a neutral detergent. Do not use strong soap or
chemical detergents. All cleaning agents should be
promptly flushed from the surface and not allowed to
dry there. Rinse the vehicle thoroughly with plenty of
lukewarm water. Wipe the remaining water off with a
chamois or soft cloth.
NOTE y
Before having your vehicle washed in an auto-
matic car wash, retract the pillar mounted antenna
to prevent it from being damaged.y When having your vehicle washed in an auto-
matic car wash, make sure beforehand that the car
wash is of suitable type. Automatic car wash
brushes or other equipment may damage the rear
wiper and rear/roof spoiler (if equipped). T Washing the underbody
Chemicals, salts and gravel used for deicing road sur-
faces are extremely corrosive, accelerating the corro-
sion of underbody components, such as the exhaust
system, fuel and brake lines, brake cables, floor pan
and fenders, and suspension.
Thoroughly flush the underbody and inside of the
fenders with lukewarm or cold water at frequent inter-
vals to reduce the harmful effects of such agents.

Winter (snow) tires
Winter tires are best suited for driving on snow-cov-
ered and icy roads. However winter tires do not per-
form as well as summer tires and all season tires on
roads other than snow-covered and icy roads. „ Tire inspection
Check on a daily basis that the tires are free from se-
rious damage, nails, and stones. At the same time,
check the tires for abnormal wear.
Contact your SUBARU dealer immediately if you find
any problem.
NOTE y When the wheels and tires strike curbs or are
subjected to harsh treatment as when the vehicle
is driven on a rough surface, they can suffer dam-
age that cannot be seen with the naked eye. This
type of damage does not become evident until
time has passed. Try not to drive over curbs, pot-
holes or on other rough surfaces. If doing so is un-
avoidable, keep the vehicle’s speed down to a
walking pace or less, and approach the curbs as
squarely as possible. Also, make sure the tires are
not pressed against the curb when you park the
vehicle. y If you feel unusual vibration while driving or find it difficult to steer the vehicle in a straight line, one
of the tires and/or wheels may be damaged. Drive
slowly to the nearest authorized SUBARU dealer
and have the vehicle inspected. „
Tire pressures and wear
Maintaining the correct tire pressures helps to maxi-
mize the tires’ service lives and is essential for good
running performance. Check and, if necessary, adjust
the pressure of each tire (including the spare) at least
once a month (for example, during a fuel stop) and be-
fore any long journey.
Check the tire pressures when the tires are cold. Use
