Engine Overheating
319
In Case of Emergency9
– CONTINUED –
9-5. Engine Overheating■If Steam Is Coming from the
Engine CompartmentTurn off the engine and get everyone
away from the vehicle until it cools down.
■ If No Steam Is Coming from
the Engine Compartment1. Keep the engine running at idling
speed.
2. Open the hood to ventilate the engine
compartment. Refer to "Engine Hood"
 P343.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays in the over-
heated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank.
If the coolant level is below the “LOW”
mark, add coolant up to the “FULL” mark.NOTEFor details about how to check the
coolant level or how to add coolant,
refer to "Eng ine Coolant" P349.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the radiator cap, then turn the cap

counterclockwise slowly without pressing
down until it stops. Release the pressure
from the radiator. After the pressure has
been fully released, remove the cap by
pressing down and turning it.
WARNING
Never remove the radiator cap until
the engine has been shut off and
has fully cooled down. When the
engine is hot, the coolant is under
pressure. Removing the cap while
the engine is still hot could release
a spray of boiling hot coolant,
which could burn you very seri-
ously.
CAUTION
If the engine overheats, the engine
speed or the vehicle speed may be
reduced. Stop the vehicle in a safe
place immediately.

324holes, return the plugs to their original
places.■Using a Flat-Bed Truck
This is the best way to transport your
vehicle. Use the following procedures to
ensure safe transportation.
1. Shift the select lever into the “P” posi-
tion for AT models. Sh ift the shift lever into
the 1st position for MT models.
2. Apply the parking brake firmly.
3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out.
■ Towing with All Wheels on
the Ground
WARNING
Use the rear tie-down holes only for
downward anchoring. If they are
used to anchor the vehicle in any
other direction, cables may slip out
of the holes, possibly causing a
dangerous situation.
900488
CAUTION
Transport by flat -bed truck may
cause the headlights to become
misaligned. In such a case, have the
headlight alignment checked by a
SUBARU dealer after transporting
the vehicle by flat-bed truck.
WARNING
 Never turn the ignition switch to
the “OFF” position while the
vehicle is being towed because
the steering wheel and the direc-
tion of the wheels will be locked. Remember that the brake booster
and power steering do not func-
tion when the engine is not
running. Because the engine is
turned off, it w ill take greater
effort to operate the brake pedal
and steering wheel.

damaged condition. In that case,
use a flat-bed truck for transpor-
tation. The traveling speed must be
limited to less than 20 mph (32
km/h) and the traveling distance
to less than 19 miles (30 km). For
greater speeds and distances,
transport your vehicle on a flat-
bed truck. Use a flat-bed truck if there are
long distance downgrades or
steep slopes. However, do not
apply the brake pedal for a long
time because the engine braking
will not work while towing. Doing
so could overheat the brake. Drive carefully and do not make
an impact on the towing rope by
suddenly starting.
 Use a specific towing rope for
towing. If wire ropes and metal
chains are needed to be used for
towing, wrap the contact portion
of the bumper with cloth to
protect it from damage.

Exterior Care
33210-1. Exterior Care■Washing
NOTE
When having your vehicle washed in
an automatic car wash, make sure
beforehand that the car wash is of
suitable type.
The best way to preserve your vehicle’s
beauty is frequent 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 lukewarm or cold water. Do not wash
the vehicle with hot water and in direct
sunlight.
Salt, chemicals, insects, tar, soot, tree
sap, and bird droppings should be washed
off by using a light detergent, as required.
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. Wear rubber gloves and use a hand
brush when washing down underbody,
inner fenders and suspension to effec-
tively remove mud and dirt off.
▼ Washing the underbody
Chemicals, salts and gravel used for
deicing road surfaces are extremely corro-
sive, accelerating the corrosion of under-
body 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 intervals to reduce
the harmful effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-
sion.
After driving off-road or on muddy or
sandy roads, wash the mud and sand off
the underbody.
Carefully flush the suspension and axle
parts, as they are particularly prone to
mud and sand buildup. Do not use a
sharp-edged tool to remove caked mud.
CAUTION
 When washing the vehicle, the
brakes may get wet. As a result,
the brake stopping distance 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. Do not wash the engine compart-
ment and areas adjacent to it. If
water enters the engine air intake
or electrical parts, it will cause
engine trouble or a malfunction of
the power steering. When washing inner fenders,
underbody, bumpers and
protruding objects such as
exhaust pipes and exhaust
finishers, be careful to prevent
injuries from contacting sharp
ends.
 Do not use any organic solvents
when washing the surface of the
bulb assembly cover. However, if
a detergent with organic solvents
is used to wash the cover surface,
completely rinse off the detergent
with water. Otherwise, the cover
surface may be damaged.

Appearance Care10
– CONTINUED –
▼Using a warm water washer
 Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle.
 Do not wash the same area continu-
ously.
 If a stain will not come out easily, wash
by hand. Some warm water washers are
of the high temperature, high pressure
type, and they can damage or deform the
resin parts such as moldings, or cause
water to leak in to the vehicle.■Waxing and PolishingAlways wash and dry the vehicle before
waxing and polishing.
Use a good quality polish and wax and
apply them according to the manufac-
turer’s instructions. Wax or polish when
the painted surface is cool. Be sure to polish and wax the chrome trim,

as well as the painted surfaces. Loss of
wax on a painted surface leads to loss of
the original luster and also quickens the
deterioration of the surface. It is recom-
mended that a coat of wax be applied at
least once a month, or whenever the
surface no longer repels water.
If the appearance of the paint has dimin-
ished to the point wher e the luster or tone
cannot be restored, lightly polish the
surface with a fine-grained compound.
Never polish just the affected area, but
include the surrounding area as well.
Always polish in only one direction. A No.
2000 grain compound is recommended.
Never use a coarse-grained compound.
Coarser grained compounds have a
smaller grain-size number and could
damage the paint. After polishing with a
compound, coat with wax to restore the
original luster. Frequent polishing with a
compound or an incorrect polishing tech-
nique will result in removing the paint layer
and exposing the undercoat. When in
doubt, it is always best to contact your
SUBARU dealer or an auto paint
specialist.
NOTEBe careful not to block the windshield
washer nozzles with wax when waxing
the vehicle.■ Cleaning Alloy WheelsPromptly wipe the alloy wheels clean of
any kind of grime or agent. If dirt is left on
too long, it may be difficult to clean off.
 Do not use soap containing grit to clean
the wheels. Be sure to use a neutral
cleaning agent, and later rinse thoroughly
with water. Do not clean the wheels with a
stiff brush or expose them to a high-speed
washing device.
 Clean the vehicle (including the alloy
wheels) with water as soon as possible
when it has been splashed with sea water,
exposed to sea breezes, or driven on
roads treated with salt or other agents.
CAUTION
 Be careful not to damage brake
hoses, sensor harnesses, and
other parts when washing
suspension components. Be careful not to flush the engine
bottom for a long time. It may
cause damage of some electrical
parts.
CAUTION
Do not use any agents with organic
solvents on the surface of the bulb
assembly cover. However, if a pol-
ish or wax with organic solvents is
applied to the cover surface, com-
pletely wipe off the polish or wax.
Otherwise, the cover surface may
be damaged.
