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.
NOTICE
■
When handling jumper cables
When connecting the jumper cables, 
ensure that they do not become entan-
gled in the cooling fan or engine drive 
belt.
■
To prevent damaging the vehicle
The exclusive jump starting terminal is to 
be used when chargi ng the battery from 
another vehicle in an emergency. It can-
not be used to jump start another vehicle.

If your engine knocks●
Consult your Lexus dealer.●
You may occasionally notice light knock-
ing for a short time while accelerating or 
driving uphill. This is normal and there is 
no need for concern.
NOTICE■
Notice on fuel quality●
Do not use improper fuels. If improper 
fuels are used, the engine will be dam-
aged.●
Do not use leaded gasoline.
Leaded gasoline can cause damage to 
your vehicle’s three-way catalytic con-
verters causing the emission control 
system to malfunction.●
Do not use gasohol other than the type 
previously stated.
Other gasohol may cause fuel system 
damage or vehicle performance prob-
lems.
●
Using unleaded gasoline with an 
octane number or rating lower than 
the level previously  stated may cause 
persistent he avy knocking.
At worst, this may lead to engine dam-
age and will void the vehicle warranty.
■
When refueling with gasohol
Take care not to spill  gasohol. It can dam-
age your vehicle’s paint.
■
Fuel-related poor driveability
If poor driveability is encountered after 
using a different type of fuel (poor hot 
starting, vaporization, engine knocking, 
etc.), discontinue the use of that type of 
fuel.
