Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, before recharging: ●
If recharging with the battery installed on the vehicle, be sure to disconnect the
ground cable. ●
Make sure the power switch on the charger is off when connecting and discon-
necting the charger cables to the battery.■
After recharging/reconnecting the battery
The engine may not start. Follow the procedure below to initialize the system.
Depress the brake pedal with the shift lever in “P” or “N”.
Open and close any of the doors.
Restart the engine.
CAUTION■
Chemicals in the battery
A battery contains poisonous and corrosive sulfuric acid and may produce hydro-
gen gas which is flammable and explosive. To reduce the risk of death or serious
injury, take the following precautions while working on or near battery: ●
Do not cause sparks by touching the battery terminals with tools. ●
Do not smoke or light a match near the battery. ●
Avoid contact with eyes, skin and clothes. ●
Never inhale or swallow electrolyte. ●

Where to safely charge the battery
Always charge the battery in an open area. Do not charge the battery in a garage or
closed room where there is not sufficient ventilation. ■
How to recharge the battery
Only perform a slow charge (5A or less). The battery may explode if charged at a
quicker rate. ■
Emergency measures regarding electrolyte ●
If electrolyte gets in your eyes
Flush your eyes with clean water for at least 15 minutes and get immediate medi-
cal 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 atten-
tion 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 imme-
diately.
NOTICE■
When recharging the battery
Never recharge the battery while the engine is running. Also, be sure all accesso-
ries are turned off.

Maintenance and care
LX570_OM_OM60L21U_(U) Washer fluid
If any washer does not work or the
warning message appears on the
multi-information display, the
washer tank may be empty. Add
washer fluid.
CAUTION■
When refilling the washer fluid
Do not refill the washer fluid when the engine is hot or running, as the washer fluid
contains alcohol and may catch fire if spilled on the engine etc.
NOTICE■
Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces. ■
Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the label of the washer fluid bottle.

LX570_OM_OM60L21U_(U) Tires Replace or rotate tires in accordance with tread wear.
■ Checking tires
New tread
Treadwear indicator
Worn tread The location of treadwear indi-
cators is shown by the “TWI” or
“ ” marks, etc., molded on the
sidewall of each tire.
Check spare tire condition and
inflation pressure if not rotated.
■ Tire rotation
Rotate the tires in the order
shown. To equalize tire wear and extend
tire life, Lexus recommends that
tire rotation is carried out at the
same interval as tire inspection.
Do not fail to initialize the tire
pressure warning system after
rotating the tires that the tire
pressure has been changed for
towing. (  P. 76 3 )
■ The tire pressure warning system
Your Lexus is equipped with a tire pressure warning system that uses
tire pressure warning valves and tr ansmitters to detec t low tire infla-
tion pressure before serious problems arise. (  P. 8 2 4 )Front

Maintenance and care
LX570_OM_OM60L21U_(U) 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 va lves and transmitters are installed,
new tire pressure warning valve and transmitter ID codes must be regis-
tered in the tire pressure warning computer and tire pressure warning
system must be initialized. Have tire pressure warning valve and transmit-
ter ID codes registered by your Lexus dealer. (  P. 76 4 )
Initializing the tire pressure warning system
■ The tire pressure warning system must be initialized in the following
circumstances:
● When the set tire pressure has been changed before towing.
(  P. 8 8 9 )
● When rotating the tires in above situation.
When the tire pressure warning sy stem is initialized, the current tire
inflation pressure is set as the benchmark pressure.

7644-3. Do-it-yourself maintenance
LX570_OM_OM60L21U_(U) ■ How to initialize the tire pressure warning system
Park the vehicle in safe plac e and turn the “ENGINE START
STOP” switch to OFF. While the vehicle is moving, initialization is not performed.
Adjust the tire inflation pressure to the specified co ld tire inflation
pressure level. (  P. 8 8 9 )Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.
Turn the “ENGINE START STOP” switch to IGNITION ON
mode.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times and a message
appears on the multi-information
display.
Wait for a few minutes with the IGNITION ON mode, and then
turn the “ENGINE START STOP” switch to OFF.
Registering ID codes
The tire pressure warning valve and transmitter is equipped with a unique
ID code. When replacing a tire pressu re warning valve and transmitter, it
is necessary to register the ID code of tire pressure warning valve and
transmitter. Have the ID code re gistered by your Lexus dealer.STEP 1

When to replace your vehicle’s tires
Tires should be replaced if: ●
You have tire damage such as cuts, splits, cracks deep enough to expose the
fabric or bulges indicating internal damage ●
A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with your Lexus dealer. ■
Replacing tires and wheels
If the ID code of the tire pressure warn ing valve and transmitter is not registered,
the tire pressure warning system will not work properly. After driving for about 20
minutes, the tire pressure warning light comes on after blinking for 1 minute to indi-
cate a system malfunction. ■
Tire life
Any tire over 6 years old must be checked by a qualified technician even if they
have seldom or never been used or damage is not obvious. ■
If the tread wears down 0.16 in. (4 mm) or more on snow tires
The effectiveness of snow tires is lost.

Maximum load of tire
Check that the number given by dividing the maximum load by 1.10 of the replace-
ment tire is greater than 1 /2 of the Gr oss Axle Weight Ratings (GAWR) of either
the front axle or the rear axle, whichever is greater.

Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway driving
under dry conditions. Since summer tires do not have the same traction perfor-
mance as snow tires, summer tires are inadequate for driving on snow-covered
or icy roads. For driving on snow-covered roads or icy roads, the use of snow tires
is recommended. When installing snow tires, be sure to replace all four tires.
2 All season tires
All season tires are designed to provide better traction in snow and to be ade-
quate for driving in most winter conditions , as well as for use year round. All sea-
son tires, however, do not have adequa te traction performance compared with
snow tires in heavy or loos e snow. Also, all season tires fall short in acceleration
and handling performance compared with summer tires in highway driving.
3Snow tires
For driving on snow-covered roads or ic y roads, we recommend using snow tires.
If you need snow tires, select tires of the same size, construction and load capac-
ity as the originally installed tires. Since your vehicle has radial tires as original
equipment, make sure your snow tires also have radial construction. Do not install
studded tires without first checking loca l regulations for possible restriction.
Snow tires should be installed on all wheels. (  P. 3 74 )For the GAWR, see the Certification Label.
For the maximum load of the tire, see the load
limit at maximum cold tire inflation pressure
mentioned on the sidewall of the tire.
