Maintenance requirements
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
For full details of your maintenance schedule, refer to the “Lexus Service
Booklet” or “Lexus Warranty Booklet”.
What about do-it-yourself maintenance?
Many maintenance items are easy to do yourself if you have a little mechani-
cal 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 experi-
enced do-it-yourself mechanic, we recommend that repairs and maintenance
be conducted by any authorized Lexus dealer or repairer, or another duly qual-
ified and equipped professional. Any authorized Lexus dealer 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 pro-
fessional 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 regular
maintenance are essential. Lexus recommends the following mainte-
nance:

Where to go for maintenance service?
In order to maintain your vehicle in the best possible condition, Lexus recom-
mends that maintenance service operations as well as other inspections and
repairs be carried out by authorized Lexus dealers or repairers or other duly qual-
ified and equipped professionals. For repairs and services covered by your war-
ranty, 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 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 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 condition-
ing 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 imme-
diately.)
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. 570, 583)
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 possi-
ble. Your vehicle may need adjustment or repair.

Maintenance and care

The engine compartment contains many mechanisms and fluids that may move
suddenly, become hot, or become electrically energized. To avoid death or seri-
ous injury, observe the following precautions.
When working on the engine compartment
Make sure that the indicator on the power switch and the “READY” indicator
are both off.
Keep hands, clothing and tools away from the moving fan.
Be careful not to touch the engine, power control unit, radiator, exhaust mani-
fold, etc. right after driving as they may be hot. Oil and other fluids may also
be hot.
Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are
flammable.
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 immediately. If you still experience discomfort, consult
a doctor.
When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature is
high. (P. 502)
Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in your eyes.
NOTICE
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.
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.

Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.
After installing the support rod into the slot
Make sure the rod supports the hood securely from falling down on to your
head or body.
NOTICE
When closing the hood
Be sure to return the support rod to its clip before closing the hood. Closing the
hood without returning the support rod properly could cause the hood to bend.
