Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year
to maintain 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 possi-
ble.
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.
Doing so may cause electrical components etc. to malfunction or catch
fire.
Do not get any of the SRS components or wiring in the vehicle interior
wet.
(P. 1 1 1 )
Electrical malfunction may cause the airbags to deploy or not function
properly, 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.

line solutions, dye, bleach or other detergent. Doing so may discolor the
vehicle interior or cause streaks or damage to painted surfaces.
Do not use polish wax or polish cleaner. The instrument panel's or other
interior part’s painted surface may be damaged.
Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces.
Remove any dust or dirt on leather surfaces immediately.
Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
Do not place items made of vinyl, plastic, or that contain wax on the
upholstery, as they may stick to the leather surface if the vehicle interior
heats up significantly.
Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust.
Cleaning the inside of the rear window
Do not use glass cleaner to clean the rear window, as this may cause dam-
age to the rear window defogger heater wires or antenna. Use a cloth
dampened with lukewarm water to gently wipe the window clean. Wipe
the window in strokes running parallel to the heater wires or antenna.
Be careful not to scratch or damage the heater wires or antenna.

Maintenance requirements
To ensure safe and economical driving, day-to-day care and regular
maintenance is essential. Lexus recommends the following mainte-
nance.
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 lit-
tle 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 useful should you ever
require Warranty Service. Should you choose to select a qualified
and equipped professional other than an authorized Lexus repairer

Where to go for service?
In order to maintain your vehicle in the highest possible condition, Lexus
recommends that all repairs and service operations be carried out by autho-
rized 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 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 pro-
fessional service department will perform all of the scheduled maintenance
on your vehicle - reliably and economically due to their experience with
Lexus vehicles.
Does your vehicle need repair?
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 after use is normal.)
Change in exhaust sound (This may indicate a dangerous carbon monox-
ide 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 driving 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
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.
