RX350/270_EE
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlapping circles. Do not apply water. Excellent
results are obtained by keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Do not splash or spill liquid in the vehicle.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
(→P. 1 3 2 )
An electrical malfunction may cause the airbags to deploy or not function prop-
erly, resulting in death or severe injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off the
windshield, obstructing the driver's view and leading to an accident, resulting in
death or serious injury.

4-2. Maintenance
Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular main-
tenance are essential. Lexus recommends the following maintenance:
■Scheduled maintenance
Scheduled maintenance should be performed at specified intervals
according to the maintenance schedule.
For full details of your maintenance schedule, read the “Lexus Service
Booklet” or “Lexus Warranty Booklet”.
■Do-it-yourself maintenance
What about do-it-yourself maintenance?
Many 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 autho-
rized 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 professional other than an
authorized Lexus repairer to service or maintain your vehicle, we recom-
mend 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 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 utiliz-
ing 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 econom-
ically 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 indi-
cate 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 driving straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches
the floors, vehicle pulls to one side when braking
●Engine coolant temperature continually higher than normal
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.

CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precaution:
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fans and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driv-
ing 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 or the battery. Fuel
and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
●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 “ENGINE START STOP” switch is off.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fans may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. (→P. 4 7 8 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in your eyes
