■Before recharging
When recharging, the battery produces hydr ogen gas which is flammable and explosive. Therefore, observe the following precautions 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 disconnecting the charger cables to the battery.
■After recharging/reconnecting the battery
●The engine may not start. Follow the pr ocedure below to initialize the system.
Shift the shift lever to P.
Open and close any of the doors.
Restart the engine.
●Unlocking the doors using the smart entry & start system may not be possible immedi-
ately after reconnecting the battery. If this happens, use the wireless remote control or the mechanical key to lock/unlock the doors.
●Start the engine with the engine switch in ACCESSORY mode. The engine may not
start with the engine switch turned off. However, the engine will operate normally from the second attempt.
●The engine switch mode is recorded by the vehicle. If the battery is disconnected and
reconnected, the vehicle will return the engi ne switch mode to the status it was in before the battery was disconnected. Make sure to turn off the engine switch beforedisconnecting the battery. Take extra care when connecting the battery if the engine
switch mode prior to the battery being disconnected is unknown.
If the system will not start even after multip le attempts at all the methods above, contact any authorized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.

If none of the washer do not work or the
“Windshield Washer Fluid Low”
appears on the multi-information dis-
play, the washer tank may be empty.
Add washer fluid.
Washer fluid
WARNING
■When adding washer fluid
Do not add washer fluid when the engine is hot or operating as 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

Check if the treadwear indicators are showing on the tires. Also check the tires
for uneven wear, such as excessive wear on one side of the tread.
Check the spare tire condition and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicat ors is shown by a “TWI” or “” mark, etc., molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.

Rotate the tires in the order shown.
To equalize tire wear and help extend tire life, Lexus recommends that you rotate your tires approximately at the following intervals:
2WD models:
Every 10000 km (6000 miles)
AWD models: Every 5000 km (3000 miles)
Do not fail to initialize the tire pressure warning system after tire rotation.

Your vehicle is equipped with a tire pressure warning system that uses tire pres-
sure warning valves and transmitters to detect low tire inflation pressure before
serious problems arise.
Tire pressure warning system
●The tire pressure detected by the tire
pressure warning system can be dis-
played on the multi-information display.
The illustration used is intended as an exam- ple, and may differ from the image that is
actually displayed on the multi-information display.
●If the tire pressure drops below a prede-
termined level, the driver is warned by a
screen display and a warning light.

◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and transmitters
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. 617)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following circum-
stances:
●When the tire inflation pressure is changed such as when changing
traveling speed.
●When the tire inflation pressure is changed such as when the tire size is
changed.
●When rotating the tires
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 engine switch off.
Initialization cannot be perfor med while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation pressure
level. ( P. 737)
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 switch to IGNITION ON mode.
Select on the multi-information display. ( P. 110)
Press or of the meter control switch, select the “Vehicle Settings”
screen and then press the .
Press or of the meter con-
trol switch, select the “TPMS”
screen and then press and hold
the until the tire pressure
warning light blinks slowly 3
times.
“- -” will be displayed for inflation pressure of each tire on the multi-information display while the tire
pressure warning system determines the position of each tire.
When position of each tire is determined, the inflation pressure of each tire will be
displayed on the multi-information display.
Drive the vehicle at approximately 40 km/h (25 mph) or more for approx-
imately 10 to 30 minutes until the inflation pressure of each tire is displayed
on the multi-information display.
If tire inflation pressure becomes low before the inflation pressure is displayed, the tire pressure warning light will come on.
Depending on the vehicle and driving co nditions, initialization may take up to
approximately 1 hour to complete.
