■

When replacing the 12-volt bat-

tery

●

Use a 12-volt battery that con-

forms to European regulations.

●

Use a 12-volt battery that the case

size is same as the previous one

(LN1), 20 hour rate capacity

(20HR) is equivalent (45Ah) or

greater, and performance rating

(CCA) is equivalent (286A) or

greater.

• If the sizes differ, the 12-volt bat-

tery cannot be properly secured.

• If an improper 12-volt battery is

used, battery performance may

decrease and the EV system may

not be able to restart.

• If the 20 hour rate capacity is low,

even if the time period where the

vehicle is not used is a short time,

the 12-volt battery may discharge

and EV system may not be able to

start.

For details, consult your SUBARU

dealer.

WARNING

■

When removing the 12-volt

battery terminals

Always remove the negative (-)

terminal first. If the positive (+) ter-

minal contacts any metal in the

surrounding area when the posi-

tive (+) terminal is removed, a

spark may occur, leading to a fire

in addition to electrical shocks

and death or serious injury.

■

Avoiding 12-volt battery fires

or explosions

Observe the following precautions

to prevent accidentally igniting the

flammable gas that may be emit-

ted from the 12-volt battery:

●

Make sure each jumper cable is

connected to the correct termi-

nal and that it is not unintention-

ally in contact with any other

than the intended terminal.

●

Do not allow the other end of

the jumper cable connected to

the “+” terminal to come into

contact with any other parts or

metal surfaces in the area, such

as brackets or unpainted metal.

●

Do not allow the + and - clamps

of the jumper cables to come

into contact with each other.

●

Do not smoke, use matches,

cigarette lighters or allow open

flame near the 12-volt battery.

■

12-volt battery precautions

The 12-volt battery contains poi-

sonous and corrosive acidic elec-

trolyte, while related parts contain

lead and lead compounds.

Observe the following precautions

when handling the 12-volt battery:

●

When working with the 12-volt

battery, always wear safety

glasses and take care not to

allow any battery fluids (acid) to

come into contact with skin,

clothing or the vehicle body.

●

Do not lean over the 12-volt bat-

tery.

Wait until the “EV System
overheated Output power
reduced” message disap-

WARNING

●

In the event that battery fluid

(acid) comes into contact with

the skin or eyes, immediately

wash the affected area with

water and seek medical atten-

tion.

Place a wet sponge or cloth

over the affected area until

medical attention can be

received.

●

Always wash your hands after

handling the 12-volt battery and

other battery-related parts.

●

Do not allow children near the

12-volt battery.

■

When replacing the 12-volt

battery

●

When the vent plug is close to

the hold down clamp, the bat-

tery fluid (acid) may leak.

●

For information regarding bat-

tery replacement, contact your

SUBARU dealer.

NOTICE

■

When handling jumper cables

When connecting the jumper

cables, ensure that they do not

become entangled in the cooling

fan.

If your vehicle over-

heats

When “EV System over-
heated Output power
reduced” is shown on the
multi-information display,
your vehicle may be over-
heating.

NOTICE

■

Cooling system coolant

The radiator coolant is exclusive

for radiator usage. Damage may

occur when water or any other

type of coolant is used, so never

use any other fluid. When there is

no “Genuine Traction Battery

Coolant”, immediately contact

your SUBARU dealer.

Your SUBARU dealer will help
answer any questions you may
have as you read this information.

■

DOT quality grades

All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades. Quality grades
can be found where applicable
on the tire sidewall between
tread shoulder and maximum
section width.

For example: Treadwear 200 Trac-
tion AA Temperature A

■

Treadwear

The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course.

For example, a tire graded 150
would wear one and a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use. Performance may differ
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.

■

Traction AA, A, B, C

The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement

as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.

A tire marked C may have poor
traction performance.
Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.

■

Temperature A, B, C

The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.

Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
