■Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dang
erous loss of braking efficiency. Use only
newly opened brake fluid.
WARNING
■When filling the reservoir
Take care because brake fluid can harm yo ur hands or eyes and damage painted sur-
faces. If fluid gets on your eyes, flush the affected area with clean water immediately. If
you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when
the fluid level in the accumulator is high. If the reservoir needs freq uent refilling, it may
indicate a serious problem.

Maintenance and care
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and explosive.
Therefore, observe the following 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 procedure 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 access system with push-button start may not be
possible immediately 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 reconnected, the
vehicle will return the engine switch mode to the status it was in before the battery was
disconnected. Make sure to turn off the engine before disconnect the battery. Take
extra care when connecting the battery if the engine switch mode prior to discharge is
unknown.
If the system will not start even after mult iple attempts, contact your Lexus dealer.

Maintenance and care
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.
●If the tire pressure drops below a predet ermined level, the driver is warned by
a screen display and a warning light. ( P. 520)
●The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information
display. ( P. 93)
The illustration used is intended as an
example, and may differ from the image
that is actually disp layed on the multi-
information display.
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pr essure warning valves and transmitters
must also be installed.
When new tire pressure wa rning 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. ( P. 475)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the following circum-
stances:
●When changing the tire size.
●When rotating the tires.
●When the tire inflation pressure is changed such as when changing travel-
ing speed or load weight.
●After registering the ID codes. ( P. 475)
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 st op the engine for 20 minutes or more.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to th e specified cold tire inflation pressure
level. ( P. 568)
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.
Start the engine. (P. 200)
Press or of the meter control switches and select .
Press or of the meter control switches and select “Vehicle
Settings”, and then press .
Press or of the meter control switches and select “TPWS”, and
then press .
Press or of the meter
control switches and select “Set
Pressure”, and then press and
hold until the tire pressure
warning light starts blinking.
A message is displayed on the multi-
information display. Also, “--” is dis-
played for inflation pressure of each
tire on the multi-information display
while the tire pressure warning sys-
tem determines the position.
Drive at approximately 25 mph (40 km /h) or more for approximately 10 to
30 minutes.
When initialization is comple te, the inflation pressure of each tire will be displayed
on the multi-information display.
Even if the vehicle is not driven at ap proximately 25 mph (40 km/h) or more, ini-
tialization can be co mpleted by driving for a long ti me. However, if initialization
does not complete after driving for 1 hour or more, park the vehicle in a safe place
for approximately 20 minutes and then drive the vehicle again.
