4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
Automatic car washes
Fold the mirrors back before washing the vehicle.
Brushes used in automatic car washes may scratch the vehicle surface
and harm your vehicle’s paint.
Turn the wipers off before washing the vehicle.
High pressure car washes
Do not allow the nozzles of the car wash to come within close proximity
of the windows.
Before car wash, check that the fuel filler door on your vehicle is closed
properly.
Touch-up paint (if equipped)
Touch-up paint may be used to cover small chips or scratches.
Apply the paint soon after the damage occurs or corrosion may set in. To
apply the touch-up paint so it is hardly noticeable the trick is to apply it only
to the bare spots. Apply only the smallest amount possible and do not paint
the surface around the scratch or chip.
Perform the following to protect the vehicle and maintain it in prime
condition.
Working from top to bottom, liberally apply water to the
vehicle body, wheel wells and underside of the vehicle to
remove any dirt and dust.
Wash the vehicle body using a sponge or soft cloth, such as
a chamois.
For hard-to-remove marks, use car wash soap and rinse
thoroughly with water.
Wipe away any water.
Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehi-
cle body is cool.

NOTICE
Cleaning detergents
Do not use organic substances such as benzene or gasoline, acidic or alka-
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.

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.
Any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional service department will perform all of the scheduled
maintenance on your vehicle - reliably and economically due to their experi-
ence 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.

After a fuse is replaced
If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. (P. 407)
If the replaced fuse blows again, have the vehicle inspected by any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
