or greater, and performance rating (CCA)
is equivalent (689A) or greater.
Type B: Use a battery that the case size is
same as the previous one (LN4), 20 hours
rate capacity (20HR) is equivalent (75Ah)
or greater, and performance rating (CCA)
is equivalent (776A) or greater.
• If the sizes differ, the battery cannot be
properly secured.
• If the 20 hour rate capacity is low, even if
the time period where the vehicle is not
used is a short time, the battery may dis-
charge and engine may not be able to
start.
O For details, consult your Lexus dealer.
Q When recharging or replacing the bat-
tery (vehicles with Stop & Start system)
The Stop & Start system may not automati-
cally stop the engine for up to an hour.
Q When removing the battery termi-
nals
Always remove the negative (-) terminal
first. If the positive (+) terminal contacts
any metal in the surrounding area when
the positive (+) terminal is removed, a
spark may occur, leading to a fire in addi-
tion to electrical shocks and death or
serious injury.
Q Avoiding battery fires or explosions
Observe the following precautions to
prevent accidentally igniting the flamma-
ble gas that may be emitted from the bat-
tery:
O Make sure each jumper cable is con-
nected to the correct terminal and that
it is not unintentionally in contact with
any other than the intended terminal.
O Do not allow the other end of the
jumper cable connected to the “+” ter-
minal to come into contact with any
other parts or metal surfaces in the
area, such as brackets or unpainted
metal.
O Do not allow the + and - clamps of the
jumper cables to come into contact
with each other.
O Do not smoke, use matches, cigarette
lighters or allow open flame near the
battery.
Q Battery precautions
The battery contains poisonous and cor-
rosive acidic electrolyte, while related
parts contain lead and lead compounds.
Observe the following precautions when
handling the battery:
O When working with the 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.
O Do not lean over the battery.
O In the event that battery fluid comes
into contact with the skin or eyes,
immediately wash the affected area
with water and seek medical attention.
Place a wet sponge or cloth over the
affected area until medical attention
can be received.
O Always wash your hands after han-
dling the battery support, terminals,
and other battery-related parts.
O Do not allow children near the battery.
