Recommendations for Windshield Wiper Maintenance, Cleaning, and Use:
1. Scheduled Maintenance
Check wiper rubber blades every 4 ± 6 months or 7,500 miles for wear, cracking,
and contamination.
Clean glass and rubber wiper blades if blades are not clearing glass adequately.
If this does not correct the problem, then replace the rubber elements.
2. Cleaning Procedure
Wiper Rubber: Bugs, dirt, sap, and road grime on blades will cause streaking.
Clean wiper rubber of road and environmental debris using cloth or paper towel
soaked with windshield washer fluid or mild detergent.
DO NOT USE fuel, kerosene, or petroleum based products to clean rubber
wiper blades.
Windshield: Bugs, sap, road grime, and car wash wax treatments decrease
wiper performance.
Rinse windshield with water and apply non±abrasive cleaner, such as Bon±Ami
(www.faultless.com), with a sponge.
NOTE:
Make sure to use plenty of water with all powder based cleaners so the glass is
not scratched.

Information Bulletin
November 10, 2005
BO012-05
TSIB UPDATE NOTICE:
The information contained in this TSIB supercedes TSIB No. BO004-98.
TSIB No. BO004-98 is now obsolete and should be discarded.
Beginning in 1997, Lexus introduced side airbags for the LS 400. Starting with 1998,
all Lexus vehicles are equipped with side airbags as standard equipment.
Lexus does NOT recommend replacement of original seat covers* with non-Lexus leather
or other seat cover materials due to the following:
Seat covers NOT recommended by Lexus may affect side airbag performance, in
general or in part, during an accident.
Modifications that negatively affect side airbag performance can result in severe
occupant injuries.
Seat covers are an integral part of this safety system. Replacing original seat covers*
with non-Lexus leather or other seat cover materials may compromise the
effectiveness of this safety system.
The design of the seat is complex, integrating safety and strength with comfort
and luxury.
*NOTE:
Lexus original seat covers that were NOT designed for side airbag equipped seats
cannot be used due to the effect on proper airbag performance.
Lexus strongly discourages modifying original equipment seats that have
side airbags.
Additionally, Lexus strongly advises against the installation or use of aftermarket
seat covers, which could impair the performance of the side airbags in the event of
an accident.
All 1997 ± 2006 model year Lexus vehicles.
