Maintenance requirements
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
For details about maintenance items and schedules, refer to the “Lexus
Service Booklet” 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 tasks require special tools and
skills. These are best performed by qualified technicians. Even if you’re
an experienced do-it-yourself mechanic, we recommend that repairs and
maintenance be conducted by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional. Any authorized Lexus
dealer or repairer will keep a record of maintenance, which could be use-
ful 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.
To ensure safe and economical driving, day-to-day care and regu-
lar maintenance are essential. Lexus recommends the following

Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus rec-
ommends 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 professionals. 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 advantages in utilizing authorized Lexus dealers or repair-
ers 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 profes-
sional will perform all of the scheduled maintenance on your vehicle reliably
and economically due to their experience with Lexus vehicles.
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 condi-
tioning system 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 1 0 )
If you notice any of these clues, take your vehicle to any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.
