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 daytoday
care is more important than ever before to ensure smooth,
troublefree, 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 the Owner’s Guide, Owner’s Manual Supplement
or Warranty Booklet for complete warranty information.
General maintenance
General maintenance items are those daytoday 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 the ”Owner’s Manual
Supplement/Maintenance Schedule” are those required to be
serviced at regular intervals.For details of your maintenance schedule, read the separate
”Owner ’s Manual Supplement/Maintenance Schedule”.
It is recommended that any replacement parts used for
maintenance or for the repair of the emission control system be
Lexus supplied.
The owner may elect to use nonLexus 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 systems.
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, Owner’s
Manual Supplement or Warranty Booklet for complete
warranty information.
Where to go for service?
Lexus technicians are welltrained specialists and are kept up to date
with the latest service information through technical bulletins,
service tips, and indealership training programs. They are well
informed about the operation of all the systems on your vehicle.
You can be confident that your Lexus dealer’s service department
performs the best job to meet the maintenance requirements of your
vehicle reliably and economically.
