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

may need adjustment or repair.



Scheduled maintenance should be
performed at specified intervals
according to the maintenance
schedule.

The interval for scheduled maintenance is
determined by the odometer reading or
the time interval, whichever comes first,
shown in the schedule.
Maintenance beyond the last period
should be performed at the same intervals.



Where to go for maintenance ser-
vice?

It makes good sense to take your vehicle to
your local Lexus dealer for maintenance
service as well as other inspections and
repairs.

Maintenance requirements
(For India)

To ensure safe and economical driv-
ing, day-to-day care and regular
maintenance are essential. Lexus
recommends the following mainte-
nance:

WARNING

Q

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.

Q

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. (

6-2. Maintenance

Lexus technicians are well-trained special-
ists receiving the latest service information
through technical bulletins, service tips and
in-dealership training programs. They
learn to work on Lexus before they work
on your vehicle, rather than while they are
working on it. Doesn’t that seem like the
best way?
Your Lexus dealer has invested a lot of
money in special Lexus tools and service
equipment. It helps them to do the job bet-
ter and at less cost.
Your Lexus dealer’s service department
will perform all of the scheduled mainte-
nance on your vehicle reliably and eco-
nomically.
Rubber hoses (for cooling and heater sys-
tem, brake system and fuel system) should
be inspected by a qualified technician
according to the Lexus maintenance
schedule.
Rubber hoses are particularly important
maintenance items. Have any deteriorated
or damaged hoses replaced immediately.
Note that rubber hoses will deteriorate
with age, resulting in swelling, chafing or
cracking.

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.
Simple instructions for how to perform
them are presented in this section.
Note, however, that some maintenance
tasks require special tools and skills. These
are best performed by qualified techni-
cians. Even if you are an experienced do-it-

yourself mechanic, we recommend that
repairs and maintenance be conducted by
your Lexus dealer who will keep a record
of maintenance on your vehicle. This
record could be helpful should you ever
require Warranty Service.

Q

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:

O

Engine missing, stumbling or pinging

O

Appreciable loss of power

O

Strange engine noises

O

A fluid leak under the vehicle (However,

water dripping from the air conditioning

system after use is normal.)

O

Change in exhaust sound (This may indi-

cate a dangerous carbon monoxide leak.

Drive with the windows open and have

the exhaust system checked immedi-

ately.)

O

Flat-looking tires, excessive tire squeal

when cornering, uneven tire wear

O

Vehicle pulls to one side when driven

straight on a level road

O

Strange noises related to suspension

movement

O

Loss of brake effectiveness, spongy feel-

ing brake pedal, pedal almost touches the

floor, vehicle pulls to one side when brak-

ing

O

Engine coolant temperature continually

higher than normal (

P.102)

If you notice any of these clues, take your

vehicle to your Lexus dealer as soon as pos-

sible. Your vehicle may need adjustment or

repair.

Scheduled maintenance (For India)

Perform maintenance by the schedule as follows:

Maintenance schedule requirements

Your vehicle needs to be serviced according to the normal maintenance schedule. (See
“Maintenance schedule”.)

If you mainly operate your vehicle under one or more of the special operating conditions
below, some of the maintenance schedule items need to be serviced more frequently in
order to keep your vehicle in good condition. (See “Additional maintenance schedule”.)

A. Road Conditions
1. Operating on rough or muddy roads, or
roads with melted snow.
2. Operating on dusty roads. (Roads in areas
where their pavement rate is low, or a cloud
of dust often arises and the air is dry.)

B. Driving Conditions
1. Heavily loaded vehicle. (Example: Using a
camper, using a car top carrier, etc.)
2. Extensive idling and/or low speed driving
for a long distance such as police, profes-
sional / private use like taxi or door-to-door
delivery use.
3. Continuous high speed driving (80% or
more of maximum vehicle speed) for over 2
hours.

(6000 miles) since the last oil change. This may cause the maintenance reminder
appear even when driven less than 10000 km (6000 miles). Replace both engine
oil and oil filter every 5000 km (3000 miles) or 6 months, in which the vehicle is
mainly driven in dirt or dusty roads, when the maintenance reminder does not
appear.
2. After 80000 km (48000 miles) or 48 months inspection, inspect every
20000 km (12000 miles) or 12 months.
3. First replace at 160000 km (100000 miles), then replace every 80000 km
(50000 miles).
4. First replace at 240000 km (150000 miles), then replace every 80000 km
(50000 miles).
5. Including the filter in fuel tank.
6. Parking brake inspection is not necessary.

Refer to the following table for normal maintenance schedule items requiring more
frequent service specific to the type of severe conditions. (For outline, see “Mainte-
nance schedule requirements”.)

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.

Q

When working on the engine com-

partment

O

LC500h: Make sure that the “IGNI-

TION ON” on the multi-information

display and the “READY” indicator are

both off.

O

Keep hands, clothing and tools away

from the moving fan and engine drive

belt.

O

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.

O

Do not leave anything that may burn

easily, such as paper and rags, in the

engine compartment.

O

Do not smoke, cause sparks or expose

an open flame to fuel. Fuel fumes are

flammable.

O

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.

Q

When working near the electric cool-

ing fan or radiator grille

Be sure the engine switch <power

switch> is off.

With the engine switch <power switch> in

IGNITION ON mode <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.392)

Q

Safety glasses

Wear safety glasses to prevent flying or

falling material, fluid spray, etc. from get-

ting in your eyes.

NOTICE

Q

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.

Q

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.
