■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)

Maintenance and care
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (However, water dripping from the air conditioning

ately.)
●Flat-looking tires, excessive tire squeal
when cornering, uneven tire wear
●Vehicle pulls to one side when driven
straight on a level road
●Strange noises related to suspension
movement
●Loss of brake effectiveness, spongy feel-
ing brake pedal, pedal almost touches the floor, vehicle pulls to one side when brak-ing

If you notice any of these clues, take your vehicle to any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer as soon as possible. Your vehicle

Maintenance and care
WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become elec-
trically energized. To avoid death or seri- ous injury, observe the following precautions.
■When working on the engine com-
partment
●LC500h: Make sure that the “IGNI-
TION ON” on the multi-information display and the “READY” indicator are both off.
●Keep hands, clothing and tools away
from the moving fan and engine drive belt.
●LC500: Be careful not to touch the engine, radiator, exhaust manifold, etc.
right after driving as they may be hot. Oil and other fluids may also be hot.LC500h: Be careful not to touch the
engine, power control unit, radiator, exhaust manifold, etc. right after driv-ing as they may be hot. Oil and other
fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine compartment.
●Do not smoke, cause sparks or expose
an open flame to fuel. Fuel fumes are flammable.
●Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the affected area with clean water imme-
diately. If you still experience discomfort, con-sult a doctor.
■When working near the electric cool-ing fan or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode , the electric cooling fan may automatically
start to run if the air conditioning is on and/or the coolant temperature is high. ( P.323)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from get-
ting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter
removed may cause excessive engine wear due to dirt in the air.
■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 frequent refilling, it may indicate a serious problem.
