LS500_OM_OM50F54U_(U) WARNING■
When removing the battery terminals
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, leadin g to a fire in addi-
tion to electrical shocks and death or
serious injury. ■
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: ●
Make sure each jumper cable is con-
nected to the correct terminal and that
it is not unintentiona lly in contact with
any other than the intended terminal.●
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.●
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
battery.
■
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:
●
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.
●
Do not lean over the battery. ●
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. ●
Always wash your ha nds after handling
the battery support, terminals, and
other battery-related parts. ●
Do not allow children near the battery. ■
After recharging the battery
Have the battery inspected at your Lexus
dealer as soon as possible.
If the battery is deteriorating, continued
use may cause the battery to emit a mal-
odorous gas, which may be detrimental
to the health of passengers. ■
When replacing the battery ●
When the vent plug and indicator are
close to the hold down clamp, the bat-
tery fluid (sulfuric acid) may leak. ●
For information regarding battery
replacement, contact your Lexus
dealer. ●
After replacing, se curely attach the
exhaust hose and exhaust hole plug to
the exhaust hole of the replaced bat-
tery. If not properly installed, gases
(hydrogen) may leak into the vehicle
interior, and there is the possible dan-
ger of the gas igniting and exploding.

gled in the cooling fan or engine drive
belt.
