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.

Periodic Inspections
2928-5. Periodic InspectionsTo keep your vehicle in the best condition
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 "F uel Requirements"
 P223.
 Comply with all regulations and
requirements of each country.
8-7. Driving Tips
WARNING
 Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden
braking or under other similar
conditions. When replacing or installing
tire(s), all four tires must be the
same for the following items.
(a) Size(b) Speed symbol(c) Load index(d) Circumference(e) Construction(f) Manufacturer(g) Brand (tread pattern)(h) Degrees of wearFor items (a) to (c), you must
obey the specification that is
printed on the ti re inflation pres-
sure label. The tire inflation pres-
sure label is located on the

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
RoadsTo 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.

Loading Your Vehicle
298
NOTEFor better fuel economy, do not carry
unneeded cargo.
■ Vehicle Capacity WeightThe 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
the vehicle.

weight of the driver and all passengers,
their belongings, and any optional equip-
ment.■ GVWR and GAWR (Gross
Veh icle Weight Rating an d
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.
