Maintenance and care

■High-pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the windows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed prop-
erly.
■Notes for a smart entry & start system (vehicles with entry function)
If the door handle becomes wet while the electronic key is within the effective range, the
door may lock and unlock repeatedly. In that case, follow the following correction proce-
dures to wash the vehicle:
●Place the key in a position 2 m (6 ft.) or more separate from the vehicle while the vehi-
cle is being washed. (Take care to ensure that the key is not stolen.)
●Set the electronic key to battery-saving mode to disable the smart entry & start system.
( → P. 1 5 5 )
■Aluminum wheels
●Remove any dirt immediately by using a neut ral detergent. Do not use hard brushes or
abrasive cleaners. Do not use strong or harsh chemical cleaners.
Use the same mild detergent and wax as used on the paint.
●Do not use detergent on the wheels when they are hot, for example after driving for
long distance in the hot weather.
●Wash detergent from the wheels immediately after use.
■Brake caliper coating (vehicles with orange brake calipers for F SPORT models)
●When using detergent, use neutral detergent.
Do not use hard brushes or abrasive cleaners, as they will damage the coating.
●Do not use detergent on the brake calipers when they are hot.
●Wash detergent off immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
■Front side windows water-repellent coating
●The following precautions can extend the effectiveness of the water-repellent coating.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate on the windows for a long period. Clean the windows with a soft, damp cloth as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when cleaning the windows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance has become insufficient, the coating can be
repaired. Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.

■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 use water. Wipe dirty surfaces and let
them dry. Excellent results are obtained by keeping the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water us ing a cloth or sponge. Also check the belts
periodically for excessive wear, fraying or cuts.
■When cleaning the carpeted portions of the glove box, console box, etc.
If a strong adhesive tape is used, there is a possibility that the surface of the carpet could
be damaged.
WA R N I N G
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, such as on the floor, in the hybrid battery
(traction battery) air vents, and in the trunk.
Doing so may cause the hybrid battery, electrical components, etc. to malfunction or
catch fire.
●Do not get any of the SRS components or wiring in the vehicle interior wet. ( →P. 44)
An electrical malfunction may cause the airbags to deploy or not function properly,
resulting in death or serious injury.
■Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect off the wind-
shield, obstructing the driver’s view and leading to an accident, resulting in death or
serious injury.

4146-2. Maintenance
GS450h_300h_OM_OM30F00E_(EE)
■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 conditioning sys-
tem 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 0 5 )
If you notice any of these clues, take your vehicle to any authorized Lexus dealer or
repairer, or another duly qualified and equipp ed professional as soon as possible. Your
vehicle may need adjustment or repair.
