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 "Fuel 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
driver’s center pillar.

8-8. Winter Driving■
Operation during Cold
Weather
Carry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small shovel and jumper cables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winter
starts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
Keep the door locks from freezing by
squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen, use
hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that
contains an antifr eeze solution. Do not
use engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
If you fill the windshield washer tank with
a fluid with a different concentration from
If all four tires are not the same in
items (a) to (h), serious mechani-
cal damage could be caused to
the drivetrain of the car, and
affect the followings.- Ride- Handling- Braking- Speedometer/Odometer cali-
bration- Clearance between the bodyand the tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
In a rollover crash, an unbelted
person is significantly more likely
to die than a person wearing a
seat belt. The driver and all your
passengers should fasten their
seatbelts before st arting to drive
in order to minimize the chance of
serious injury or death. Do not make sharp turns or quick
maneuvers unless absolutely
unavoidable. Such actions are
dangerous as you may lose
control, possibly resulting in a
rollover which could cause death
or serious injury.
Whenever strong crosswinds are
present, slow do wn sufficiently to
maintain control of your vehicle. Never to drive through pools and
puddles, or roads flooded with
water. Water entering the engine
air intake or the exhaust pipe or
water splashing onto electrical
parts may damage your vehicle
and may cause it to stall. In this
case, contact your SUBARU
dealer immediat ely. Regardless
of its depth, it can wash away the
ground from under your tires,
resulting in possible loss of trac-
tion and even vehicle rollover.
CAUTION
After driving on gravel roads or
rough roads, check the undercar-
riage of the vehicle body for any
damage, deformation, or paint
removal. If you notice any irregulari-
ties, contact a SUBARU dealer for
an inspection as soon as possible.

Winter Driving
294the one used previously, purge the old
fluid from the piping between the wind-
shield washer tank and washer nozzles by
operating the washer for a certain period
of time. Otherwise, if the concentration of
the fluid remaining in the piping is too low
for the outside temperature, it may freeze
and block the nozzles.▼
Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery and
driving dangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has accu-
mulated under the fenders to avoid
making steering difficult. During severe
winter driving, stop when and where it is
safe to do so and check under the fenders
periodically.
▼Parking in cold weather
CAUTION
Adjust the washer fluid concen-
tration appropriately for the
outside temperature. If the
concentration is inappropriate,
sprayed washer fluid may freeze
on the windshield and obstruct
your view, and the fluid may
freeze in the windshield washer
tank.State or local regulations on vola-
tile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle’s paint, wiper blades
or washer system.
WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you
park the vehicle in snow with the
engine running.
CAUTION
Do not use the parking brake
when parking for long periods in
cold weather since it could freeze
in that position.When the vehicle is parked in
snow or when it snows, raise the
wiper blades off the glass to
prevent damage to them.Under either of the following
conditions, icing may develop on
the brake system, which could
cause poor braking action.
- When the vehicle has been left
parked after use on roads
heavily covered with snow- When the vehicle has been leftparked during a snowstormCheck for snow or ice buildup on
the suspension, disc brakes and
brake hoses underneath the vehi-
cle. If there is caked snow or ice,
remove it, being careful not to
damage the disc brakes and
brake hoses and ABS harness.
