■When using a car wash (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.

distance in hot weather.
●Wash detergent from the wheels immediately after use.

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 th e front side windows regularly. • Do not allow dirt and dust to accumula te on the windows for a long period.
Clean the windows with a soft, damp cloth as soon as possible.

■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 cl eaners 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 luke warm water using 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.
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehicle, su ch as on the floor, in the hybrid battery (traction battery) air vents, and in the trunk.
Doing so may cause the hybrid battery, elec trical 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 ma y 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.

authorized Lexus retailer or re pairer will keep a record of maintenance, which could be useful should you ever require Warrant y Service. Should you choose to select a
qualified and equipped professional other th an an authorized Lexus repairer to ser-
vice or maintain your vehicle, we recommen d that you request that a record of main-
tenance be kept.
