hicle control and cause death or serious injury.
●Use tires of the specified size.
●Maintain the recommended level of air pressure.
●Do not drive in excess of 75 mph (120 km/h), regardless of the type of snow tires
being used.
●Use snow tires on all, not just some wheels.
●Do not use LDA (Lane Departure Alert) system. (if equipped)
■Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed limit specified for the tire chains being used, or 30
mph (50 km/h), whichever is lower.
●Avoid driving on bumpy road surfaces or over potholes.
●Avoid sudden acceleration, abrupt steering, sudden braking and shifting operations
that cause sudden engine braking.

■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legitimate tire

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 surface if the vehicle interior heats up significantly.
■When cleaning the inside of the windshield (vehicles with LDA [Lane Departure
Alert])
Be careful not to touch the camera sensor (→P. 2 2 8 ) .
If the camera is accidentally scratched or hit, LDA may not operate properly or may
cause a malfunction.
■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.
