7-1. Maintenance and care
●Working from top to bottom, liberally apply water to the vehicle body, wheel
wells and underside of the vehicle to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thoroughly with
water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is cool.
■Self-restoring coat
The vehicle body has a self-restoring coating that is resistant to small surface scratches caused in a car wash etc.
●The coating lasts for 5 to 8 years from when the vehicle is delivered from the plant.
●The restoration time differs depending on the depth of the scratch and outside tem-perature.
The restoration time may become shorter when the coating is warmed by applying warm water.
●Deep scratches caused by keys, coins, etc. cannot be restored.
●Do not use wax that contains abrasives.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of the vehicle.
Make sure to extend th e mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle body and damage the paint.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the windows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed prop-
erly.

■When using a car wash
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.( P. 157)
■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 a longdistance in hot weather.
●Wash detergent from the wheels immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
■Side windows water-repellent coating
●The following precautions can extend the effectiveness of the water-repellent coating.
• Remove any dirt, etc. from the 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 co ntain abrasives when cleaning the windows. • Do not use any metallic objects to remove condensation build up.
●When the water-repellent performance has become insufficient, the coating can be
repaired. Contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
