8-1. New Vehicle Break-In
Driving – the First 1,000 miles
(1,600 km)
s08aa
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 ac-
celeration, 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 Hints
s08ab
The 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
maintain that speed for as long as possi-
ble.
. 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 under the door
latch on the driver’s side. 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.
. The indication of the ECO gauge shows
a reference for saving fuel. For details,
refer to “ECO gauge” �P206.
8-3. Engine Exhaust Gas
(Carbon Monoxide)
s08ac
WARNING
. Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
. Always properly maintain the en-
gine 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 ve-
hicle for a long time while the
engine is running. If that is un-
avoidable, 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 al-
ways works properly.

. 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 (Legacy) or rear
gate (Outback/Subaru Outback
Wilderness) closed while driving
to prevent exhaust gas from en-
tering the vehicle.
NOTE
Due 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 ex-
haust system for a short time after the
engine has been shut off. This sound is
normal.
8-4. Catalytic Converter
s08ad
WARNING
. Avoid fire hazards. Do not drive
or park the vehicle anywhere
near flammable materials (e.g.
grass, paper, rags or leaves),
because the catalytic converter
operates at very high tempera-
tures.
. Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.

The 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 ignition 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
