Maintenance requirements
Scheduled maintenance should be performed at specified intervals according to
the maintenance schedule.
For details about maintenance items and sche
dules, refer to the “Lexus Service Book-
let” or “Lexus Warranty Booklet”.
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.
Note, however, that some maintenance ta sks require special tools and skills. These
are best performed by qualified technicians. Even if you’re an experienced do-it-your-
self mechanic, we recommend that repairs and maintenance be conducted by any
authorized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional. Any authorized Lexus dealer or re pairer 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.
■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 dealers or repairers or other duly qualified and equipped profes-
sionals. For repairs and services covered by your warranty, please visit an authorized
Lexus dealer or repairer, who will use genuine Lexus parts in repairing any difficulties you
may encounter. There can also be advantag es in utilizing authorized Lexus dealers 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 dealer or repairer, or another duly qualified and equipped professional will
perform all of the scheduled maintenance on your vehicle reliably and economically due
to their experience with Lexus vehicles.
To ensure safe and economical driving, day-to-day care and regular mainte-
nance are essential. Lexus recommends the following maintenance:

■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:
●Engine missing, stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (However, water dripping from the air conditioning sys-
tem after use is normal.)
●Change in exhaust sound (This may indicate a dangerous carbon monoxide leak. Drive
with the windows open and have the exhaust system checked immediately.)
●Flat-looking tires, excessive tire squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches the floor,
vehicle pulls to one side when braking
●Engine coolant temperature continually higher than normal ( →P. 1 0 5 )
If you notice any of these clues, take your vehicle to any authorized Lexus dealer or
repairer, or another duly qualified and equipp ed professional as soon as possible. Your
vehicle may need adjustment or repair.
