Maintenance and care
■Aluminum wheels
●Remove any dirt immediately by using a neutral 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.
■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.

●When the water-repellent performance has become insufficient, the coating can be
repaired. Contact your Lexus dealer.

■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may cause the
electrical components etc. to catch fire.
■When cleaning the windshield (vehicles with rain-sensing windshield wipers)
●When the upper part of the windshield where the raindrop sensor is located is
touched by hand
●When a wet rag or similar is held close to the raindrop sensor
●If something bumps against the windshield
●If you directly touch the raindrop sensor bo dy or if something bumps into the raindrop
sensor
■Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled suffi-
ciently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the switch is in “AUTO”, the wipers may oper-
ate unexpectedly in the following situations,
and may result in hands being caught or other
serious injuries and cause damage to the wiper
blades.

■Repair and replacement
It is recommended that genuine Lexus parts be used for repairs to ensure performance
of each system. If non-Lexus parts are used in replacement or if a repair shop other than
a Lexus dealer performs repairs, confirm the warranty coverage.
■Resetting the message indicating maintenance is required (U.S.A. only)
After the required maintenance is preforme
d according to the maintenance schedule,
please reset the message.
To reset the message, follow the procedures described below:
Switch the display to the trip meter “A” ( →P. 84) when the hybrid system is operating.
Turn the power switch off.
While pressing the odometer/trip meter display change button ( →P. 84), turn the
power switch to ON mode (do not start the hybrid system because otherwise the reset
mode will be canceled). Continue to press and hold the button until the trip meter dis-
plays “000000” and the multi-information disp lay indicates that the reset is complete.
■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained specialists and are kept up to date with the latest ser-
vice information. They are well informed about the operation of all systems on your
vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been per-
formed is under warranty coverage. If any problem should arise while your vehicle is
under warranty, your Lexus dealer will promptly take care of it.
WA R N I N G
■If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and possible seri-
ous injury or death.
■Handling of the 12-volt battery
●Engine exhaust, some of its constituents, and a wide variety of automobile compo-
nents contain or emit chemicals known to the State of California to cause cancer and
birth defects and other reproductive harm. Work in a well ventilated area.
●Oils, fuels and fluids contained in vehicles as well as waste produced by component
wear contain or emit chemicals known to the State of California to cause cancer and
birth defects or other reproductive harm. Avoid exposure and wash any affected area
immediately.
●12-volt battery posts, terminals and related accessories contain lead and lead com-
pounds which are known to cause brain damage. Wash your hands after handling.

The engine compartment contains many mechan isms and fluids that may move suddenly,
become hot, or become electrically energize d. To avoid death or serious 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 manifold, 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 flamma-
ble.
■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 automatically start to
run if the air conditioning is on and/or the coolant temperature is high. ( →P. 4 8 2 )
■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.
