ing that is resistant to small surface
scratches caused in a car wash, etc.
O
The coating lasts for 5 to 8 years from

for leather.
Q
Caring for leather areas
Lexus recommends cleaning the interior of
the vehicle at least twice a year to maintain
the quality of the vehicle’s interior.
Q
Dirt on the synthetic leather areas
Ingrained dirt which has been left
uncleaned for long periods of time is diffi-
cult to clean. Lexus recommends cleaning
the area regularly.

6-2.Maintenance
Q
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
retailer 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 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.
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
Maintenance requirements
To ensure safe and economical
driving, day-to-day care and regu-
lar maintenance are essential.
Lexus recommends the following
maintenance:
WARNING
Q
If your vehicle is not properly main-
tained
Improper maintenance could result in
serious damage to the vehicle and possi-
ble serious injury or death.
Q
Handling of the 12-volt battery
12-volt battery posts, terminals and
related accessories contain lead and

WARNING
O
Keep hands, clothing and tools away
from the moving fan and engine drive
belt.
O
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.
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 discom-
fort, consult a doctor.
Q
When working near the electric cool-
ing fans or radiator grille
Be sure the power switch is OFF.
With the power switch in ON, the elec-
tric cooling fans may automatically start
to run if the air conditioning is on and/or
the coolant temperature is high.
(
P.375)
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.
