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 luggage compartment.
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. 3 8 )
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 le ading to an accident, resulting in death or
serious injury.
NOTICE
■Cleaning detergents
●Do not use the following types of detergent, as they may discolor the vehicle interior
or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances su ch as benzene or gasoline, alkaline or
acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alcohol
●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 from 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 containing 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 such as the audio system above or under the floor of the
vehicle. Water 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 damage to the
rear window defogger heater wires or antenna. Use a cloth dampened with luke-
warm 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 and care
Maintenance requirements
General maintenance should be performed
on a daily basis. This can be done by
yourself or by a Lexus dealer.
Scheduled maintenance should be performed at specified intervals according to
the maintenance schedule.
For details about maintenance items and schedules, refer to the “Warranty and Ser-
vice Guide”, “Owner’s Manual Supplement” or “Scheduled Maintenance”.
You can perform some maintenance procedures by yourself.
Please be aware that do-it-yourself maintenance may affect warranty coverage.
The use of Lexus repair manuals is recommended.
For details about warranty coverage, refer to the separate “Owner’s Guide”, “War-
ranty and Service Guide”, “Owner’s Manual Supplement” or “Warranty Booklet”.
To ensure safe and economical driving, day-to-day care and regular mainte-
nance are essential. It is the owner’s responsibility to perform regular checks.

■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.

Emission inspection and maintenance (I/M) programs
The OBD system determines that a problem exists somewhere in the emission
control system. Your vehicle may not pass the I/M test and may need to be
repaired. Contact your Lexus dealer to service the vehicle.
●When the 12-volt battery is disconnected or discharged
Readiness codes that are set during ordinary driving are erased.
Also, depending on your driving habits, the readiness codes may not be com-
pletely set.
●When the fuel tank cap is loose
The malfunction indicator lamp comes on indicating a temporary malfunction
and your vehicle may not pass the I/M test.
The error code in the OBD system will not be cleared unless the vehicle is driven
40 or more times.
Contact your Lexus dealer to prepare the vehicle for re-testing.
Some states have vehicle emission inspection programs which include OBD
(On Board Diagnostics) checks. The OBD system monitors the operation of
the emission control system.
If the malfunction indicator lamp comes on
Your vehicle may not pass the I/M test in the following situations:
When the malfunction indicator lamp still remains on after several driv-
ing trips
If your vehicle does not pass the I/M test
