WARNING
■When the Emergency Call may not be made
●Any of the followings may occur. In such cases, report to the Public Safety
Answering Point (PSAP) by other means such as nearby public phones.
• It may sometimes be difficult to con- nect to the Public Safety Answering Point (PSAP) even in the reception
area of the cellular phone due to the reception level, or if the line is busy.In such cases, you may not be able to
connect to the Public Safety Answer- ing Point (PSAP) and thus will not be able to make emergency calls and
report to the emergency departments even though the system tries to con-nect to the Public Safety Answering
Point (PSAP).
• When the vehicle is out of the cellular
phone service area, the Emergency Call cannot be made.
• When any related equipment (such as the “SOS” button panel, indicator lights, microphone, speaker, DCM,
antenna, or any wires connecting the equipment.) has an abnormality, is damaged or broken, the Emergency
Call cannot be made.
• During the Emergency Call, the sys-
tem makes repeated attempts to con- nect to the Public Safety Answering Point (PSAP). However, if it cannot
connect to the Public Safety Answer- ing Point (PSAP) due to poor radio wave reception, the system may not be
able to connect to the cellular network and the call may finish without con-necting. The red indicator light will
blink for approximately 30 seconds to indicate this disconnection.
• This device may not function if a shock is applied to it.

■Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recommends that maintenance service operations as well as
other inspections and repairs be carried out by authorized Lexus retailer or Lexus authorized repairer, or any reliable repair-
ers. For repairs and services covered by your warranty, please visit an authorized Lexus retailer or repairer, who will use gen-
uine Lexus parts in repairing any difficulties you may encounter. There can also be advantages in utilizing authorized Lexus
retailers or repairers for non-warranty repairs and services, as members of the Lexus network will be able to expertly assist
you with any difficulties you may encounter.
Your Lexus retailer or Lexus authorized
repairer, or any reliable repairer will per- form all of the scheduled maintenance on your vehicle reliably and economically due
to their experience with Lexus vehicles.
Scheduled maintenance should be
performed at specified intervals
according to the maintenance sched-
ule.
For details about maintenance items and
schedules, refer to the “Lexus Service
Booklet” or “Lexus Warranty Booklet”.
What about do-it-yourself mainte-
nance?
Many of the maintenance items are easy to
do yourself if you have a little mechanical
ability and a few basic automotive tools.
Note, however, that some maintenance
tasks require special tools and skills. These
are best performed by qualified techni-
cians. Even if you’re an experienced do-it-
yourself mechanic, we recommend that
repairs and maintenance be conducted by
any authorized Lexus retailer or Lexus
authorized repairer, or any reliable
repairer. Any authorized Lexus retailer or
repairer will keep a record of maintenance,
which could be useful should you ever
require Warranty Service. Should you
choose to select a qualified and equipped
professional other than an authorized
Lexus repairer to service or maintain your
vehicle, we recommend that you request
that a record of maintenance be kept.
■Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs that indicate
service is needed. Some important clues are:
●Engine missing, stumbling or pinging
Maintenance requirements
To ensure safe and economical driv-
ing, day-to-day care and regular
maintenance are essential. Lexus
recommends the following mainte-
nance:
WARNING
■If your vehicle is not properly main-
tained
Improper maintenance could result in
serious damage to the vehicle and possi- ble death or serious injury.
■Handling of the 12-volt battery
12-volt battery posts, terminals and related accessories contain lead and lead compounds which are known to
cause brain damage. Wash your hands after handling. ( P.325)

6-3. Do-it-yourself maintenance
When replacing wheels, care should
be taken to ensure that they are equiv-
alent to those removed in load capac-
ity, diameter, rim width and inset*.
Replacement wheels are available at
any authorized Lexus retailer or Lexus
authorized repairer, or any reliable
repairer.
*: Conventionally referred to as offset.
Lexus does not recommend using the
following:
 Wheels of different sizes or types
 Used wheels
 Bent wheels that have been straight-
ened
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and trans-
mitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, tire pres- sure warning valves and transmitters must be installed. ( P.335)Use only Lexus wheel nuts and
wrenches designed for use with
your aluminum wheels.
 When rotating, repairing or chang-
Wheels
If a wheel is bent, cracked or heavily
corroded, it should be replaced.
Otherwise, the tire may separate
from the wheel or cause a loss of
handling control.
Wheel selection
WARNING
■When replacing wheels
●Do not use wheels that are a different
size from those recommended in the Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leaking
wheel which is designed for a tubeless tire. Doing so may result in an acci-dent, causing death or serious injury.
■Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an acci-dent.
NOTICE
■Replacing tire pressure warning
valves and transmitters
●Because tire repair or replacement
may affect the tire pressure warning valves and transmitters, make sure to have tires serviced by any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer or other qualified service shop. In addi-
tion, make sure to purchase your tire pressure warning valves and transmit-ters at any authorized Lexus retailer or
Lexus authorized repairer, or any reli- able repairer.
●Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and trans- mitters may not work properly with non-genuine wheels.

7-2.Steps to take in an emergency
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 <power 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.
