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 retailers or Lexus

authorized repairers, 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 full details of your maintenance sched-
ule, refer to the “Lexus Service Booklet” or
“Lexus Warranty Booklet”.

What about do-it-yourself mainte-
nance?

Many maintenance items are easy to do
yourself if you have a little mechanical abil-
ity 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 con-
ducted 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.

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-

e and care

Pull the hood lock release lever.

The hood will pop up slightly.

Pull up the auxiliary catch lever and
lift the hood.

WARNING

●

Be careful not to touch the engine,

power control unit, radiator, exhaust

manifold, etc. right after driving 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.

●

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 power switch is off.

With the power switch in ON, the elec-

tric cooling fan may automatically start to

run if the air conditioning is on and/or the

coolant temperature is high. (

P.505)

■

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.

Hood

Opening the hood

WARNING

■

When the hood is open (RX500h)

Even if the power switch is turned off, the

cooling fan may continue to operate for a

short time. When the cooling fan is rotat-

ing, do not touch or approach the inside

of the engine compartment.

■

Pre-driving check

Check that the hood is fully closed and

locked.

If the hood is not locked properly, it may

open while the vehicle is in motion and

cause an accident, which may result in

death or serious injury.

Engine oil consumption

A certain amount of engine oil will be con-

sumed while driving. In the following situa-

tions, oil consumption may increase, and

engine oil may need to be refilled in

between oil maintenance intervals.

●

When the engine is new, for example

directly after purchasing the vehicle or

after replacing the engine

●

If low quality oil or oil of an inappropriate

viscosity is used

●

When driving at high engine speeds or
with a heavy load, when towing

, or when

driving while accelerating or decelerat-

ing frequently

●

When leaving the engine idling for a long

time, or when driving frequently through

heavy traffic

: Vehicles with towing package

■

Engine oil level rise

If the vehicle is repeatedly driven without

the engine warmed up, moisture caused by

dew condensation inside the engine or fuel

which did not burn mixes into the engine oil,

resulting in a rise in engine oil level. How-

ever, this is not a malfunction.
For example, the engine become difficult to

be warmed up in the following situations.

●

When driving a short distance

●

When driving at a low speed

●

When the outside temperature is low

When checking the engine oil, make sure

that the engine is warmed up. If the engine

oil level exceeds the refill upper limit mark,

contact any authorized Lexus retailer or

Lexus authorized repairer, or any reliable

repairer.
