MAINTENANCE REQUIREMENTS
Your Lexus vehicle has been designed to have fewer
maintenance requirements with longer service intervals to
save both your time and money. However, each regular
maintenance as well as day-to-day care is more important than
ever before to ensure smooth, trouble-free, safe, and
economical driving.
It is the owner’s responsibility to make sure the specified
maintenance, including general maintenance services, is
performed. Note that both the new vehicle and emission
control system warranties specify that proper maintenance
and care must be performed. See Owner’s Guide or Warranty
Booklet for complete warranty information.
General maintenance
General maintenance items are those day-to-day care
practices that are important to your vehicle for proper
operation. It is the owner’s responsibility to ensure that the
general maintenance items are performed regularly.
These checks or inspections can be done either by yourself or
your Lexus dealer.
Scheduled maintenance
The scheduled maintenance items listed in this part are those
required in servicing at regular intervals.However, under severe driving conditions, a separate
maintenance schedule that requires more frequent
maintenance service should be practiced.
It is recommended that any replacement part used for
maintenance or for the repair of the emission control
system be Lexus supplied.
The owner may elect to use non-Lexus supplied parts for
replacement purposes without invalidating the emission
control system warranty. However, use of replacement
parts which are not of equivalent quality may impair the
effectiveness of the emission control system.
You may also elect to have maintenance, replacement, or
repair of the emission control devices and system
performed by any automotive repair establishment or
individual without invalidating this warranty. See Owner’s
Guide or Warranty Booklet for complete warranty
information.
Where to go for service?
Lexus technicians are well-trained specialists and are kept up
to date with the latest service information through technical
bulletins, service tips, and in-dealership training programs.
They are well informed about the operation of all the systems
on your vehicle.

MAINTENANCE
147 You can be confident that your Lexus dealer’s service
department performs the best job to meet the maintenance
requirements of your vehicle.
Your copy of the repair order is proof that all required
maintenance has been performed for warranty coverage. And
if any problems should arise with your vehicle while under
warranty, your Lexus dealer will promptly take care of it. Again,
be sure to keep a copy of the repair order for any service
performed on your Lexus.
What about do-it-yourself maintenance?
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 Section 6.
If you are a skilled do-it-yourself mechanic, the Lexus service
manuals are recommended. Please be aware that
do-it-yourself maintenance can affect your warranty coverage.
See your Owner’s Guide or Warranty Booklet for the details.
GENERAL MAINTENANCE
Listed below are the general maintenance items that should be
performed at the intervals specified. It is recommended that
any problem you notice be brought to the attention of your
Lexus dealer or qualified service shop for their advice.
CAUTION:
Make these checks only where adequate ventilation can
be obtained if you run the engine.
Vehicle exterior
Items listed below should be performed from time to time,
unless otherwise specified.
Tires
Check the pressure with a gauge every two weeks, or at least
once a month and adjust as shown on the tire pressure label.
Check carefully for cuts, damage or excessive wear. See page
190 for additional information.
Wheel nuts
When checking the tires, make sure to check the nuts for
looseness. Tighten them if necessary.

MAINTENANCE
151 If you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.
CAUTION:
Do not continue driving with the vehicle unchecked. It
could result in serious vehicle damage and possibly
personal injury.
SCHEDULED MAINTENANCE
Driving conditions under which you mainly operate your
vehicle determine which maintenance schedule you
follow.
In order to ensure smooth, trouble-free, safe and economical
driving, Lexus provides two maintenance schedules to be
selected according to your driving conditions: schedules A and
B. The instructions on which schedule to follow are given on
the next page.
The service interval for scheduled maintenance is
determined by the odometer reading or the time interval,
whichever comes first, shown in the schedule.The maintenance services beyond the last period should
be performed at the same intervals.
The service interval of each item can be obtained from the
maintenance schedule.
