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.
