Reverse Automatic Braking
(RAB) system (if equipped)

Reverse Automatic Braking (RAB) system
is a system designed to help avoid colli-
sions or reduce collision damage when
reversing the vehicle. If a wall or an
obstacle is detected in the reversing
direction, the system will notify the driver
with a warning sound and may activate the
vehicle’s brakes automatically.

WARNING

.

Reverse Automatic Braking
(RAB) system is not a system
intended to replace the driver’s
responsibility to check surround-
ing areas for vehicles or obsta-
cles to avoid a collision.

.

The driver is responsible for driv-

ing safely. Before reversing, be
sure to first depress the brake
pedal and visually check the
surroundings.

.

There are some cases in which

the vehicle cannot avoid colli-
sion, because the system opera-
tion has limitations. The warning
sound or automatic braking may
be delayed or may not operate at
all even when an obstacle is

present.

.

The system is not designed to

detect people (including chil-
dren), animals or other moving
objects.

.

Depending on the vehicle condi-

tion or the surrounding environ-
ment, the sonar sensor’s ability
to detect objects may be compro-
mised.

.

Do not remove the SUBARU gen-

uine navigation and/or audio sys-
tem. If the SUBARU genuine
navigation and/or audio system
is removed, the rear view camera
image and help lines (distance
marker, dynamic guidelines and
vehicle width lines) will no longer
be displayed.

.

Even if the Reverse Automatic

Braking (RAB) system and object
detection warning is ON, the
visible alert of Reverse Auto-
matic Braking (RAB) system will
not be displayed. However, the
audible alert and its function will
operate.

Reverse Automatic Braking
(RAB) system overview

The 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 acti-
vate.

.

If the vehicle is further reversed, auto-

matic hard braking will be applied and a
continuous beeping sound will activate.

(350,1)

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 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 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 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.

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.
