Driving tips/New vehicle break – in driving – the first 1,000 miles (1,600 km)
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
emergency.
The same break-in procedures should be
applied to an overhauled engine, newly
mounted engine or when brake pads or
brake linings are replaced with new ones. Fuel economy hints The following suggestions will help to save
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
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 placard, 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 ” F 3-12.Engine exhaust gas (carbon
monoxide) 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 enter-
ing 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 lengthy time while
the engine is running. If that is
unavoidable, then use the venti-
lation 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 that8-2

conditions than a two wheel drive vehicle.
There is little difference in handling,
however, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an
ample distance from other vehicles.
. Always check the cold tire pressure
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, which is located under the
door latch on the driver ’ s side.
. Frequent driving of an AWD vehicle
under hard-driving conditions such as
steep hills or dusty roads will necessitate
more frequent replacement of the follow-
ing items than that specified in the
“ Warranty and Maintenance Booklet ” .
– Engine oil
– Brake fluid
– Rear differential gear oil
– Manual transmission oil (MT mod-
els)
– Continuously variable transmission
fluid (CVT models)
– Front differential gear oil (CVT
models)
. There are some precautions that you
must observe when towing your vehicle.
For detailed information, refer to “ Towing ”
F 9-12. Driving precaution 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. Never attempt to
drive through rushing water; regardless of
its depth, it can wash away the ground
from under your tires, resulting in possible
loss of traction and even vehicle rollover. 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 after-
wards thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.8-6

SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the following
table. Washer Fluid Con-
centration Freezing Temperature
30% 10.4 8 F( − 12 8 C)
50% − 4 8 F( − 20 8 C)
100% − 49 8 F( − 45 8 C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
thepipingistoolowfortheoutside
temperature, it may freeze and block the
nozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out- side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile 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.
! 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
accumulated 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
WARNINGSnow 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.
. When the vehicle has been left
parked after use on roads heavily
covered with snow, or has been
left parked during a snowstorm,
icing may develop on the brake
system, which could cause poor
braking action. Check for snow Driving tips/Winter driving

Driving tips/Winter driving
or ice buildup on the suspension,
disc brakes and brake hoses
underneath the vehicle. If there
is caked snow or ice, remove it,
being careful not to damage the
disc brakes and brake hoses and
ABS harness.
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 CVT 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 the 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
antifreeze 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 beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle ’ s braking perfor-
mance on snowy and icy roads. For
information on braking on slippery sur-
faces, refer to “ ABS (Anti-lock Brake
System) ” F 7-36 and “ Vehicle Dynamics
Control system ” F 7-38.
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
vehicle control. CAUTIONAvoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’ s intake system and may
hinder the airflow, which could re-
sult in engine shutdown or even
breakdown.
! Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window.
If the wiper blades are frozen to the
windshield, use the defroster and the
temperature set for maximum warmth until
the wiper blades are completely thawed.
Refer to “ Climate control ” F 4-1.
If your vehicle is equipped with a wiper
deicer, use it. It is helpful to thaw the
windshield wiper blades. Refer to “ Defog-
ger and deicer ” F 3-112.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
and the temperature set for maximum
warmth. After the windshield gets warmed
enough to melt the frozen snow on it,
wash it away using the windshield washer.
Refer to “ Windshield washer ” F 3-103.8-8

possible.
. Stow cargo and luggage in the
trunk whenever possible.
. To prevent cargo and luggage
from sliding forward during brak-
ing, 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.
. Do not pile heavy loads on the
roof. These loads raise the vehi-
cle ’ s center of gravity and make it
more prone to tip over.
. Secure lengthy items properly to
prevent them from shooting for-
ward 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 ped-
al 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.
NOTE For better fuel economy, do not carry
unneeded cargo. & Vehicle capacity weight
Vehicle placard
The load capacity of your vehicle is
determined by weight, not by available
cargo space. The maximum load you can
carry in your vehicle is shown on the
vehicle placard attached to the driver ’ s
side door pillar. It includes the total weight
of the driver and all passengers and their
belongings, any optional equipment such
as a roof rack or bike carrier, etc. Driving tips/Loading your vehicle

equipped) (Refer to “ Under-floor storage
compartment ” F 6-12.)
2) Tool bucket
3) Spare tire 1) Wheel nut wrench
2) Screwdriver
3) Jack
4) Towing hook (eye bolt)
A jack handle is stored under the floor of
the trunk. A jack and a towing hook are
stored in the tool bucket that is located in
the recess of the spare tire wheel. A
screwdriver and a wheel nut wrench are
stored in the vinyl bag. These tools can
also be stored in the tool bucket.
NOTE For how to use the jack, refer to “ Flat
tires ” F 9-4. Flat tires If you have a flat tire while driving, never
brake suddenly; keep driving straight
ahead while gradually reducing speed.
Then slowly pull off the road to a safe
place.
& Changing a flat tire WARNING. Do not jack up the vehicle on an
incline or a loose road surface.
The jack can come out of the
jacking point or sink into the
ground and this can result in a
severe accident.
. Use only the jack provided with
your vehicle. The jack supplied
with the vehicle is designed only
for changing a tire. Never get
under the vehicle while support-
ing the vehicle with this jack.9-4

. Always turn off the engine before
raising the flat tire off the ground
using the jack. Never swing or
push the vehicle supported with
the jack. The jack can come out
of the jacking point due to a jolt
and this can result in a severe
accident.
1. Park on a hard, level surface, when-
ever possible, then stop the engine.
2. Set the parking brake securely and
shift the shift lever in reverse (MT models)
or the select lever to the “ P ” (Park)
position (CVT models).
3. Turn on the hazard warning flasher
and have everyone get out of the vehicle.
4. Put wheel blocks at the front and rear
of the tire diagonally opposite the flat tire. 5. Take out the jack, jack handle and
wheel nut wrench.
The tools and the spare tire are stored
under the floor of the trunk. Refer to
“ Maintenance tools ” F 9-3.
NOTE Make sure that the jack is well lubri-
cated before using it.
6. Take out the tool bucket and turn the
attaching bolt counterclockwise, then take
the spare tire out.
NOTE If the spare tire provided in your vehicle
is a temporary spare tire, carefully read
“ Temporary spare tire ” F 9-2 and
strictly follow the instructions. 7. Loosen the wheel nuts using the wheel
nut wrench but do not remove the nuts.
Jack-up points
8. Place the jack under the side sill at the
front or rear jack-up point closest to the flat
tire. In case of emergency/Flat tires

In case of emergency/Flat tires
& Tire pressure monitoring
system (TPMS) (U.S.-spec.
models)
The tire pressure monitoring system pro-
vides the driver with the warning message
indicated by sending a signal from a
sensor that is installed in each wheel
when tire pressure is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven.
Also, this system may not react immedi-
ately to a sudden drop in tire pressure (for
example, a blow-out caused by running
over a sharp object).
WARNING
. If the low tire pressure warning
light illuminates while driving, never brake suddenly. Instead,
perform the following procedure.
(1) Keep driving straight ahead
while gradually reducing
speed.
(2) Slowly pull off the road to a
safe place. Otherwise an acci-
dent involving serious vehicle
damage and serious personal
injury could occur.
(3) Check the pressure for all four
tires and adjust the pressure
to the COLD tire pressure
shown on the vehicle placard
on the door pillar on the
driver ’ s side.
If this light still illuminates while
driving after adjusting the tire
pressure, a tire may have signifi-
cant damage and a fast leak that
causes the tire to lose air rapidly.
If you have a flat tire, replace it
with a spare tire as soon as
possible.
. When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/trans-
mitter being transferred, the low
tire pressure warning light will
illuminate steadily after blinking
for approximately one minute. This indicates the TPMS is un-
able to monitor all four road
wheels. Contact your SUBARU
dealer as soon as possible for
tire and sensor replacement and/
or system resetting.
. When a tire is repaired with liquid
sealant, the tire pressure warning
valve and transmitter may not
operate properly. If a liquid sea-
lant is used, contact your nearest
SUBARU dealer or other qualified
service shop as soon as possi-
ble. Make sure to replace the tire
pressure warning valve and
transmitter when replacing the
tire. You may reuse the wheel if
there is no damage to it and if the
sealant residue is properly
cleaned off.
If the light illuminates steadily
after blinking for approximately
one minute, promptly contact a
SUBARU dealer to have the sys-
tem inspected.9-8
