&Reverse Automatic Braking
System overviewThe system detects objects using sonar
sensors installed in the rear bumper. If the
system determines a possible collision
with an object in the reversing direction,
automatic deceleration will be activated.
Also, beeping sounds will activate. If the
vehicle is further reversed, automatic hard
braking will be applied and a continuous
beeping sound will activate.!Detecting range
1) Detecting range (width): Approximately 6
in (15 cm) outside of the vehicle width
2) Range that the system cannot detect:
Approximately 20 in (50 cm) behind the
rear of the vehicle
3) Detecting range (length): Approximately
5 ft (1.5 m) from the rear of the vehicle
WARNING
If your vehicle is trapped on a rail-
road crossing and you are trying to
escape by reversing through the
crossing gate, the system may re-
cognize the crossing gate as an
obstacle and the brakes may acti-
vate. In this case, remain calm and
either continue to depress the accel-
erator pedal or cancel the system. Tocancel the system, refer to“Cancel-
ing the Reverse Automatic Braking
system operation”F7-74.

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, 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 an overhauled engine, newly
mounted engine or when brake pads or
brake linings are replaced with new ones.
Fuel economy hintsThe 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 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 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”F3-12.
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 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 lengthy 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

conditions than a two wheel drive vehicle.
There is little difference in handling, how-
ever, 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 recommended
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“War-
ranty 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”
F9-21.
Driving precautionWater 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 weath-
erCarry 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 tem-
peratures 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 con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.

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-
centrationFreezing Temperature
30% 10.48F(128C)
50%48F(208C)
100%498F(458C)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
the piping is too low for the outside
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 accu-
mulated under the fenders to avoid making
steering difficult. During severe winter
driving, stop when and where it is safe todo so and check under the fenders
periodically.
!Parking in cold weather
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 you park the vehicle in
snow or when it snows, raise the
wiper blades off the glass to
prevent damage.
.Under either of the following
conditions, ice may form on the
brake system, which could cause
poor braking action.
–When the vehicle has been left
parked after use on roads
