Maintenance and care
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
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
before disconnect the 12-volt battery. Take extra care when connecting the 12-
volt battery if the power switch mode prior to discharge is unknown.
Restart the hybrid system, depress the brake pedal, and confirm that it is possi-
ble to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.

Chemicals in the 12-volt battery
The 12-volt battery contains poisonous and corrosive sulfuric acid and may
produce hydrogen gas which is flammable and explosive. To reduce the risk of
death or serious injury, take the following precautions while working on or near
the 12-volt battery:
Do not cause sparks by touching the 12-volt battery terminals with tools.
Do not smoke or light a match near the 12-volt battery.
Avoid contact with eyes, skin and clothes.
Never inhale or swallow electrolyte.
Wear protective safety glasses when working near the 12-volt battery.
Keep children away from the 12-volt battery.
Where to safely charge the 12-volt battery
Always charge the 12-volt battery in an open area. Do not charge the 12-volt
battery in a garage or closed room where there is insufficient ventilation.
How to recharge the 12-volt battery
Only perform a slow charge
*. The 12-volt battery may explode if charged at a
quicker rate.
*: 4.2 A or less on vehicles with a S46B24R battery
3.5 A or less on vehicles with a S34B20R battery
Emergency measures regarding electrolyte
If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immediate
medical attention. If possible, continue to apply water with a sponge or cloth
while traveling to the nearest medical facility.
If electrolyte gets on your skin
Wash the affected area thoroughly. If you feel pain or burning, get medical
attention immediately.
If electrolyte gets on your clothes
It can soak through clothing on to your skin. Immediately take off the clothing
and follow the procedure above if necessary.
If you accidentally swallow electrolyte
Drink a large quantity of water or milk. Get emergency medical attention
immediately.
When replacing the 12-volt battery
Use a 12-volt battery designed for this vehicle. Failure to do so may cause gas
(hydrogen) to enter the passenger compartment, causing a fire or explosion.
For replacement of the 12-volt battery, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.

NOTICE
When recharging the 12-volt battery
Never recharge the 12-volt battery while the hybrid system is operating. Also,
be sure all accessories are turned off.
Do not disconnect the negative (-) terminal
on the body side as shown. The discon-
nected negative (-) terminal may touch the

Tires
New tread
Treadwear indicator
Wo r n t r e a d
The location of treadwear indicators
is shown by the “TWI” or “”
marks, etc., molded on the sidewall
of each tire.
Check spare tire condition and pres-
sure if not rotated.
Rotate the tires in the order shown.
To equalize tire wear and help
extend tire life, Lexus recommends
that tire rotation is carried out
approximately every 10000 km
(6000 miles).
Do not fail to initialize the tire pres-
sure warning system after tire rota-
tion.
(vehicle with the tire pressure warn-
ing system)
Replace or rotate tires in accordance with maintenance schedules and
treadwear.

Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses tire
pressure warning valves and transmitters to detect low tire inflation pres-
sure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (P. 571)
Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and trans-
mitters must also be installed.
When new tire pressure warning valves and transmitters are installed,
new ID codes must be registered in the tire pressure warning computer
and the tire pressure warning system must be initialized. Have tire
pressure warning valve and transmitter ID codes registered by any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional. (P. 512)
Initializing the tire pressure warning system
The tire pressure warning system must be initialized in the following
circumstances:
Vehicles with 17 inch tires: When rotating front and rear tires which
have different tire inflation pressures
When the tire inflation pressure is changed such as when changing
traveling speed or load weight.
When changing the tire size
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.

How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the power switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (P. 645)
Make sure to adjust the tire pressure to the specified cold tire inflation pres-
sure level. The tire pressure warning system will operate based on this pres-
sure level.
Turn the power switch to ON mode.
Press and hold the tire pressure
warning reset switch until the
tire pressure warning light
blinks slowly 3 times.
Wait for a few minutes with the power switch in ON mode and then
turn the power switch off.
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
