CAUTION
The engine compartment contains many mechanisms and fluids that may move
suddenly, become hot, or become electrically energized. To avoid death or seri-
ous injury, observe the following precautions.
When working on the engine compartment
Make sure that the “ACCESSORY” or “IGNITION ON” on the multi-infor-
mation display and the “READY” indicator are both off.
Keep hands, clothing and tools away from the moving fan and engine drive
belt.
Be careful not to touch the engine, power control unit, radiator, exhaust mani-
fold, etc. right after driving as they may be hot. Oil and other fluids may also
be hot.
Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are
flammable.

The meanings of each caution symbol on the top of the 12-volt battery are
as follows:
Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flammable
and explosive. Therefore, observe the following precautions before recharging:
If recharging with the 12-volt battery installed on the vehicle, be sure to discon-
nect the ground cable.
Make sure the power switch on the charger is off when connecting and discon-
necting the charger cables to the 12-volt battery.
After recharging/reconnecting the 12-volt battery
The hybrid system may not start. Follow the procedure below to initialize the
system.
Shift the shift lever to P.
Open and close any of the doors.
Restart the hybrid system.
Unlocking the doors using the smart entry & start system may not be possible
immediately after reconnecting the 12-volt battery. If this happens, use the
wireless remote control or the mechanical key to lock/unlock the doors.
Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. However, the
hybrid system will operate normally from the second attempt.
The power switch mode is recorded by the vehicle. If the 12-volt battery is
reconnected, the vehicle will return the power switch mode to the status it was
in before the 12-volt battery was disconnected. Make sure to turn off the power
switch before disconnecting the 12-volt battery. Take extra care when connect-
ing the 12-volt battery if the power switch mode prior to the 12-volt battery
being disconnected is unknown.
If the system will not start even after multiple attempts at all the methods above,
contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.

Situations in which the tire pressure warning system may not operate properly
In the following cases, the tire pressure warning system may not operate prop-
erly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• Lock nuts are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the wheels
or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If tires not equipped with tire pressure warning valves and transmitters are
used.
• If the ID code on the tire pressure warning valves and transmitters is not reg-
istered in the tire pressure warning computer.
Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
• When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
When the vehicle is parked, the time taken for the warning to start or go off
could be extended.
When tire inflation pressure declines rapidly for example when a tire has burst,
the warning may not function.
The initialization operation
Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carrying out initialization or tire infla-
tion pressure adjustment.
If you have accidentally turned the power switch off during initialization, it is
not necessary to press the reset switch again as initialization will restart auto-
matically when the power switch has been turned to ON mode for the next time.
If you accidentally press the reset switch when initialization is not necessary,
adjust the tire inflation pressure to the specified level when the tires are cold,
and conduct initialization again.
Warning performance of the tire pressure warning system
The warning of the tire pressure warning system will change in accordance with
the conditions under which it was initialized. For this reason, the system may
give a warning even if the tire pressure does not reach a low enough level, or if
the pressure is higher than the pressure that was adjusted to when the system was
initialized.
