New Vehicle Break-In Driving – the First 1,000 miles (1,600 km)
2908-1. New Vehicle Break-In
Driving – the First 1,000 miles(1,600 km)The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km):
Do not race the engine. And do not
allow engine speed to exceed 4,000 rpm
except in an emergency.
 Do not drive at one constant engine or
vehicle speed for a long time, either fast or
slow.
 Avoid starting suddenly and rapid
acceleration, except in an emergency.
 Avoid hard braking, except in an emer-
gency.
The same break-in procedures should be
applied to a newly installed or overhauled
engine or when brake pads are replaced
with new ones.
8-2. Fuel Economy HintsThe following suggestions will help to
save your fuel.
 Select the proper gear position for the
speed and road conditions.
 Avoid sudden acceleration or decelera-
tion. Always accelerate gently until you
reach the desired speed. Then try to main-
tain that speed for as long as possible.
 Do not pump the accelerator and avoid
racing the engine.
 Avoid unnecessary engine idling.
 Keep the engine properly tuned.
 Keep the tires inflated to the correct
pressure shown on the tire inflation pres-
sure label, which is located on the driver’s
center pillar. Low pressure will increase
tire wear and fuel consumption.
 Use the air conditioner only when
necessary.
 Keep the front and rear wheels in
proper alignment.
 Avoid carrying unnecessary luggage or
cargo.
8-3. Engine Exhaust Gas(Carbon Monoxide)
WARNING
 Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is
dangerous, or even lethal, if
inhaled.Always properly maintain the
engine exhaust system to prevent
engine exhaust gas from entering
the vehicle.Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it. Avoid remaining in a parked
vehicle for a long time while the
engine is running. If that is
unavoidable, then use the ventila-
tion fan to force fresh air into the
vehicle.Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system
always works properly.

Catalytic Converter
291
Driving Tips8
NOTEDue to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the
exhaust system for a short time after
the engine has been shut off. This
sound is normal.
8-4. Catalytic ConverterThe catalytic converter is installed in the
exhaust system. It serves as catalyst to
reduce HC, CO and NOx in exhaust
gases, thus providing cleaner exhaust. To avoid damage to the catalytic
converter:

Use only unleaded gasoline. Even a
small amount of leaded gasoline will
damage the catalytic converter.
 Never start the engine by pushing or
pulling the vehicle.
 Avoid racing the engine.
 Never turn off the ig nition switch while
the vehicle is moving.
 Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer.
 Do not apply undercoating or rust
prevention treatment to the heat shield of
catalytic converter and the exhaust
system.
 Do not drive with an extremely low fuel
level.
 If at any time you suspect that
exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.Keep the trunk lid closed while
driving to prevent exhaust gas
from entering the vehicle.
WARNING
Avoid fire hazards. Do not drive
or park the vehicle anywhere near
flammable materi als (e.g. grass,
paper, rags or leaves), because
the catalytic converter operates
at very high temperatures. Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.

at all times, always have the recom-
mended maintenance services listed in
the maintenance schedule in the
“Warranty and Maintenance Booklet”
performed at the specified time or mileage
intervals.
8-6. Driving in Foreign Coun-triesWhen planning to use your vehicle in
another country:
Confirm the availability of the correct
fuel. Refer to "Fuel Requirements"
 P223.
 Comply with all regulations and
requirements of each country.

Winter Driving
295
Driving Tips8
– CONTINUED –
When parking for long periods in cold
weather, you should observe the following
tips.
1. For MT models, place the shift lever in
the “1” or “R” position. For AT models,
place the select lever in the “P” position.
2. Use tire stops under the tires to
prevent the vehicle from moving.
▼
Refueling in cold weather
To help prevent moisture from forming in
the fuel system and t he risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold
weather.
Use only additives that are specifically
designed for this purpose. When an anti-
freeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used for
an extended period, it is best to have the
fuel tank filled to capacity.
■
Driving on Snowy and Icy
Roads
To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you
to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.) Avoid shifting down abruptly. Such
behavior can cause the wheels to lock,
possibly leading to loss of vehicle control.
An anti-lock brake system (ABS)
enhances your vehicle’s braking perfor-
mance on snowy and icy roads. For infor-
mation about braking on slippery
surfaces, refer to "ABS (Anti-Lock Brake
System)"
P245 and "Vehicle Stability
Control (VSC)/TRAC System" P247.
For AT models, use the Snow mode when
driving on snowy or icy roads. For details
about how to use the mode, refer to
"Driving Mode Select Switch (If
Equipped)"  P241.
▼
Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blade rubbers are not frozen to
the windshield.
If the wiper blade rubbers are frozen to the
windshield, use the defroster with the
airflow selection in “ ” and the tempera-
ture set for maximum warmth until the
wiper blade rubbers are completely
thawed. Refer to "Cli mate Control Panel"
 P198.
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of vehi-
cle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine’s intake system and may
hinder the airflow, which could
result in engine shutdown or even
breakdown.

NOTEFor better fuel economy, do not carry
unneeded cargo.
■
Vehicle Capacity Weight
The load capacity of your vehicle is deter-
mined by weight, not by available cargo
space. The maximum load you can carry
in your vehicle is shown on the tire infla-
tion pressure label attached to the driver’s
side center pillar. It includes the total
Stow cargo and luggage in the
trunk whenever possible.To prevent cargo and luggage
from sliding forward during
braking, do not stack anything in
the enlarged trunk. Keep cargo
and luggage low, as close to the
floor as possible.When you carry something inside
the vehicle, secure it whenever
you can to prevent it from being
thrown around inside the vehicle
during sudden stops, sharp turns
or in an accident.Secure long items properly to
prevent them from shooting
forward and causing serious
injury during a sudden stop.Never exceed the maximum load
limit. If you do, some parts on
your vehicle can break, or it can
change the way your vehicle
handles. This could result in loss
of control and cause personal
injury. Also, overloading can
shorten the life of your vehicle.
Do not place cargo or luggage in
or on the following locations as
the item may get under the clutch,
brake, or accelerator pedal and
prevent the pedals from being
depressed properly, block the
driver’s vision, or hit the driver or
passengers, causing an accident:
- At the feet of the driver- On the front passenger or rear
seats (when stacking items)- On the rear shelf- On the instrument panel- On the dashboard
CAUTION
Do not carry spray cans, containers
with flammable or corrosive liquids
or any other dangerous items inside

weight of the driver and all passengers,
their belongings, and any optional equip-
ment.■
GVWR and GAWR (Gross
Vehicle Weight Rating and
Gross Axle Weight Rating)Certification labelThe certification label attached to the
driver’s side center pillar shows GVWR
(Gross Vehicle Weight Rating) and
GAWR (Gross Axle Weight Rating).
The GVW (Gross Vehicle Weight) must
never exceed the GVWR. GVW is the
combined total of weight of the vehicle,
fuel, driver, all passengers, luggage, and
any optional equipment. Therefore, the
GVW changes depending on the situation.In addition, the tota
l weight applied to
each axle (GAW) must never exceed the
GAWR. The front and rear GAWs can be
adjusted by relocating luggage inside the
vehicle.
Even if the total weight of your luggage is
lower than the vehicl e capacity weight,
either front or rear GAW may exceed the
GAWR, depending on the distribution of
the luggage.
When possible, the load should be evenly
distributed throughout the vehicle.
If you carry heavy loads in the vehicle, you
should confirm that GVW and front and
rear GAWs are within the GVWR and
GAWR by putting your vehicle on a
vehicle scale, found at a commercial
weighing station.
Do not use replacement tires with a lower
load range than the originals because
they may lower the GVWR and GAWR
limitations. Replacement tires with a
higher load range than the originals do not
increase the GVWR and GAWR limita-
tions.

Exterior Care
33210-1. Exterior Care■
WashingNOTE
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.

Corrosion Protection
334Do not use detergent on the wheels
when they are hot, such as after driving or
parking in hot weather.■
Alloy Wheels (Vehicles with
Matte P ainted Wheels)
As matte painted wheels require different
cleaning methods than conventional alloy
wheels, be sure to observe the following.
For details, consult your SUBARU dealer.
Remove dirt using water. If the wheels
are excessively dirty, use a sponge or soft
cloth dampened with a diluted neutral
detergent to remove the dirt.
 To prevent the matte paint from being
damaged, make sure to observe the
following precautions:
- Do not scrub or polish the wheels
using a brush or dry cloth.
- Do not use any wheel coatings or
abrasive detergents.
10-2. Corrosion ProtectionYour SUBARU has been designed and
built to resist corrosi on. Special materials
and protective finishes have been used on
most parts of the vehicle to help maintain
fine appearance, strength, and reliable
operation.■
Most Common Causes of
Corrosion
The most common causes of corrosion
are:
 The accumulation of moisture retaining
dirt and debris in body panel sections,
cavities, and other areas.
 Damage to paint and other protective
coatings caused by gravel and stone
chips or minor accidents.
Corrosion is accelera ted on the vehicle
when:
 It is exposed to road salt or dust control
chemicals, or used in coastal areas where
there is more salt in the air, or in areas
where there is considerable industrial
pollution.
 It is driven in areas of high humidity,
especially when temperatures range just
above freezing.
 Dampness in certain parts of the
vehicle remains for a long time, even though other parts of the vehicle may be
dry.

High temperatures will cause corrosion
to parts of the vehicle which cannot dry
quickly due to lack of proper ventilation.
■
To Help Prevent Corrosion
Wash the vehicle regularly to prevent
corrosion of the body and suspension
components. Also, wash the vehicle
promptly after driving on any of the
following surfaces.
 Roads that have been salted to prevent
them from freezing in winter
 Mud, sand, or gravel
 Coastal roads
After the winter has ended, it is recom-
mended that the underbody be given a
very thorough washing.
Before the beginning of winter, check the
condition of underbody components, such
as the exhaust system, fuel and brake
lines, brake cables, suspension, steering
system, floor pan, and fenders. If any of
them are found to be rusted, they should
be given an appropriate rust prevention
treatment or should be replaced. Contact
your SUBARU dealer to perform this kind
of maintenance and treatment if you need
assistance.
Repair chips and scratches in the paint as
soon as you find them.
