Maintenance and care
When replacing tires or wheels, tire
pressure warning valves and transmit-
ters 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. ( P.337)
■When replacing the tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered, the tire pressure warning system will not work
properly. After driving for about 10 minutes, the tire pressure warning light blinks for 1 minute and stays on to indicate a system
malfunction.
■The tire pressure warning system
must be initialized in the following
circumstances:
 When rotating the tires.
 When the tire inflation pressure is
changed when changing traveling
speed.
 When the tire inflation pressure is
changed such as when changing tire
size. (When there are multiple spec-
ified pressures)
 After registering the ID codes.
( P.337)
When the tire pressure warning system
is initialized, the current tire inflation
pressure is set as the benchmark pres-
sure.
■How to initialize the tire pressure
warning system
1 Park the vehicle in a safe place and
turn the engine switch switch> off.
Initialization cannot be performed while the vehicle is moving.
2 Adjust the tire inflation pressure to
the specified cold tire inflation pres-
sure level.
Make sure to adjust the tire pressure to the specified cold tire infl ation pressure level. The tire pressure warning system will oper-
ate based on this pressure level.
3 Turn the engine switch switch> to IGNITION ON mode
.

pressure warning light does not blink 3 times. (Initialization will not occur while driving)
●After performing init ialization, the tire pressure warning light blinks for 1 minute
then stays on after driving for about 20 minutes.
If the inflation pressure of each tire is still not
displayed, have the vehicle inspected by
any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.
■When registering ID codes
●Initialize the tire pressure warning system after ID code registra tion. Initialization is
disabled if the system was initialized before registration.
●After ID code registration, the tires are hot by driving. Initia lize the tire pressure warning system after the tires become
cold.
The tire pressure warning valve and
transmitter is equipped with a unique
ID code. When replacing a tire pres-
sure warning valve and transmitter, it is
necessary to register the ID code.
When registering the ID codes, per-
form the following procedure.
1 Turn the engine switch switch> to IGNITION ON mode
.
2 Press or of the meter con-
trol switches and select .
3 Press or of the meter con-
trol switches and select “Vehicle
Settings”, and then press “OK”.
4 Press or of the meter con-
trol switches and select “TPWS
SET”, and then press “OK”.
5 Press or of the meter con-
trol switches and select “Change
wheel set”, and then press and hold
“OK” until the tire pressure warning
light starts blinking.
The change wheel set mode is activated and registration is started.
A message is displayed on the multi-infor- mation display, and “--” is displayed for inflation pressure of e ach tire. Then, the tire
pressure warning light blinks rapidly for approximately 1 minute and stays on.
6 Drive the vehicle at 40 km/h
(25mph) or more for approxi-
mately 10 to 30 minutes.
When registration is completed, the tire pressure warning light will go off and the inflation pressure of each tire will be dis-
played on the multi-information display.
WARNING
■When initializing the tire pressure
warning system
Do not initialize tire inflation pressure
without first adjusting the tire inflation pressure to the specified level. Other-wise, the tire pressure warning light may
not come on even if the tire inflation pres- sure is low, or it may come on when the tire inflation pressure is actually normal.

6-3. Do-it-yourself maintenance
The time elapsed before registration is completed differs according to the driving condition and environment.
■Canceling the change wheel set mode
●If turning the engine switch off when in the change wheel set
mode before driving, the change wheel set mode is canceled.
●After driving when in the change wheel set mode, the change wheel set mode cannot be canceled. To cancel the mode,
perform the procedure for ID code regis- tration again and turn the engine switch off before driving.
●If the change wheel set mode is canceled, the ID codes that have already been reg-
istered are communicated. When com- munication is finished, the tire pressure warning light will turn off.
■When ID code registration may not
operate properly
●Do not move the vehicle backward
during registration. Registration is started again from the beginning and it may take longer than usual.
●When another vehicle is running the side of the vehicle such as in heavy traffic, it
may take longer to detect the vehicle’s tire pressure warning valves and trans-mitters.
●If tire pressure warning valves and trans-mitters are in the vehicle, the ID codes
may not be registered.
If registration takes long time, perform the
procedure for ID code registration again
after parking the vehicle for 20 minutes.
If the ID codes cannot be registered even
when performing the above procedure,
contact any authorized Lexus retailer or
Lexus authorized repairer, or any reliable
repairer.

If your vehicle needs to be
towed
If towing is necessary, we recom-
mend having your vehicle towed by
any authorized Lexus retailer or
Lexus authorized repairer, or any
reliable repairer or commercial
towing service, using a wheel-lift
type truck or flatbed truck.
Use a safety chain system for all
towing, and abide by all state/pro-
vincial and local laws.
WARNING
Observe the following precautions. Failure to do so may result in death or
serious injury.
■When towing the vehicle
LC500: Be sure to transport the vehicle with all four wheels raised off the ground. If the vehicle is towed with the tires con-
tacting the ground, the drivetrain and related parts may be damaged or an accident may occur due to a change in
direction of the vehicle.
LC500h: Be sure to transport the vehi- cle with all four wheels raised off the
ground. If the vehicle is towed with the tires contacting the ground, the drive-train and related parts may be damaged,
an accident may occur due to a change in direction of the vehicle or electricity generated by the operation of the motor
may cause a fire to occur depending on the nature of the damage or malfunction.
■While towing
●When towing using cables or chains, avoid sudden starts, etc. which place excessive stress on the towing eyelets,
cables or chains. The towing eyelets, cables or chains may become dam-aged, broken debris may hit people,
and cause serious damage.
●Do not turn the engine switch off.This may lead to an accident as the
rear wheels will be locked by the park- ing lock. Also, there is a possibility that the steering wheel is locked and can-
not be operated.
■Installing towing eyelets to the vehi- cle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.

ponents when the vehicle is running at a low speed for an extended period, such as in heavy traffic.
■When the 12-volt battery is removed or
discharged
●Information stored in the ECU is cleared.
When the 12-volt battery is depleted, have the vehicle inspected at any autho-rized Lexus retailer or Lexus authorized
repairer.
●Some systems may require initialization.
( P.436)
■When removing the 12-volt battery ter- minals
When the 12-volt battery terminals are removed, the information stored in the ECU is cleared. Before removing the 12-
volt battery terminals, contact any autho- rized Lexus retailer or Lexus authorized repairer.
■Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when the
vehicle is not in use, due to natural dis- charge and the draining effects of certain
electrical appliances. If the vehicle is left for a long time, the 12-volt battery may dis-charge, and the engine
may be unable to start. (The 12-volt battery recharges automatically during driving.)
■When recharging or replacing the 12-volt battery
●In some cases, it may not be possible to unlock the doors using the smart entry &
start system when the 12-volt battery is discharged. Use the wireless remote control or the mechanical key to lock or
unlock the doors.
●The engine may not start
on the first attempt after the 12-volt bat- tery has recharged but will start normally after the second attempt. This is not a
malfunction.
●The engine switch mode
is memorized by the vehicle. When the 12-volt battery is reconnected, the system will return to the mode it was in before
the 12-volt battery was discharged.
Before disconnecting the 12-volt battery, turn the engine switch off. If you are unsure what mode the engine
switch was in before the 12-volt battery discharged, be especially careful when reconnecting the 12-volt
battery.
●If the 12-volt battery discharges, it may
not be possible to shift the shift position to other positions. In this case, the vehicle cannot be towed without lifting both rear
wheels because the rear wheels will be locked. ( P.363)
■When replacing the 12-volt battery
●Use a Central Degassing type 12-volt battery (European Regulations).
●LC500: Use a 12-volt battery that the case size is same as the previous one (LN4), 20 hour rate capacity (20HR) is
equivalent (80Ah) or greater, and per- formance rating (CCA) is equivalent (685A) or greater.
LC500h: Use a 12-volt battery that the case size is same as the previous one (LN3), 20 hour rate capacity (20HR) is
equivalent (70Ah) or greater, and perfor- mance rating (CCA) is equivalent
(600A) or greater. • If the sizes differ, the 12-volt battery can-not be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehicle is not used is a short time, the 12-volt battery
may discharge and engine may not be able to start.
●Use a 12-volt battery with a handle. If a 12-volt battery without a handle is used, removal is more difficult.
●After exchanging, firmly attach the fol-lowing items to the exhaust hole of the 12-
volt battery. • Use the exhaust hose that was attached to the 12-volt battery before exchanging.
• Use the exhaust hole plug included with the 12-volt battery exchanged or the one installed on the battery prior to the
exchange. (Depending on the 12-volt battery to be exchanged, the exhaust hole may be plugged.)
