Maintenance and care
NOTICE
■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 su rface if the vehicle interior heats up significantly.
■When cleaning the inside of the windshie ld (vehicles with Lexus Safety System +)
Do not allow glass cleaner to contact the lens. Also, do not touch the lens. ( P. 2 4 6 )
■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 au dio system above or under the floor of the
vehicle. Water may also cause the body to rust.
■Cleaning the inside of the rear quarter windows and rear window
●Do not use glass cleaner to clean the rear quarter windows and rear window, as this
may cause damage to the rear window defogg er 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.

• Is the tire inflation pressure correct?
• The tires should not be damaged or excessively worn.
• Have the tires been rotated according to the mainte- nance schedule?
• The wheel nuts should not be loose.
Windshield wipers/rear

• The wiper blades should no t show any signs of crack-
ing, splitting, wear, contamination or deformation.

■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway driving under
dry conditions. Since summer tires do not have the same traction performance as
snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For
driving on snow-covered roads or icy roads, the use of snow tires is recommended.
When installing snow tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide better traction in snow and to be adequate for
driving in most winter conditions, as well as for use year round. All season tires, how-
ever, do not have adequate traction performance compared with snow tires in heavy
or loose snow. Also, all season tires fall short in acceleration and handling perfor-
mance compared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend using snow tires. If
you need snow tires, select tires of the same size, construction and load capacity as the
originally installed tires. Since your vehicle has radial tires as original equipment, make
sure your snow tires also have radial cons truction. Do not install studded tires without
first checking local regulations for possible re striction. Snow tires should be installed
on all wheels. ( P. 3 8 4 )
■Initializing the tire pressure warning system
Initialize the tire pressure warning system with the tire inflation pressure adjusted to the
specified level.
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
■If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire inflation pressure to the specified level and ini-
tialize the tire pressure warning system again.
■Situations in which the tire pressure warning system may not operate properly
●In the following cases, the tire pressure warning system may not operate properly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If the spare tire is in a location subject to poor radio wave signal reception.
• If a large metallic object wh ich can interfere with signal reception is put near the
spare tire.
• If tires not equipped with the tire pressure warning valves and transmitters are used.
• If the ID code on the tire pressure warning valves and transmitters is not registered
in the tire pressure warning computer.

■When using the mechanical key and operating the power windows or moon roof
Operate the power window or moon roof after checking to make sure that there is no
possibility of any passenger having any of their body parts caught in the window or
moon roof.
Also, do not allow children to operate the mech anical key. It is possible for children and
other passengers to get caught in the power window or moon roof.
