VEHICLE LOCATION INACCURATE

location of the vehicle using the Global Positioning System (GPS) to support features of the Safety Connect system. Due to incorrect programming in the DCM software, after November 2nd, 2019, the GPS coordinates for this system will be calculated incorrectly. This will cause the system to use incorrect vehicle coordinates if one of the system?s features is activated.

PROCESS FOR UPDATING MAP, POINTS OF INTEREST, AND SYSTEM SOFTWARE. INSTEAD OF INDIVIDUAL DVDS INSTALLED INTO THE VEHICLE, ALL MAP DATA IS UPLOADED DIRECTLY TO THE HDD SYSTEM. MAP DATA WILL BE RELEASED ANNUALLY THROUGH DIRECT SHIPMENT OF TOW MAP DATA DVDS TO EACH DEALERSHIP SERVICE MANAGER. THE ANNUAL MAP DATA RELEASE MUST THEN BE INSTALLED ONTO THE NAVIGATION UPDATE TOOL. INDIVIDUAL MAP UPDATES ARE THEN LOADED INTO THE VEHICLES WITH SPECIAL MAP SECURITY KEYS. THESE KEYS ARE AVAILABLE THROUGH THE NORMAL PARTS ORDERING SYSTEM. KEYS ARE LOADED ONTO THE NAVIGATION UPDATE TOOL THROUGH A PC OR TECHSTREAM UNIT USING SOFTWARE FOUND ON THE TECHNICAL INFORMATION SYSTEM (TIS). FOLLOW THE PROCEDURES LISTED IN THIS BULLETIN TO: IDENTIFY THE CURRENT VERSION OF MAP DATA ON THE VEHICLE AND ON THE NAVIGATION UPDATE TOOL, LOAD MAP DATA ONTO THE NAVIGATION UPDATE TOOL, LOAD MAP SECURITY KEY(S) ONTO THE NAVIGATION UPDATE TOOL, AND CONNECT THE NAVIGATION UPDATE TOOL TO THE VEHICLE AND UPDATE THE MAP/SYSTEM DATA TO THE LATEST VERSION.

THE VOLTS ARE VERY HIGH AND DANGEROUS AND CAN CAUSE SEVERE INJURIES.

rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. While Lexus paint quality, durability, and resistance to environmental factors is continuously being improved, it remains the responsibility of the dealer to protect and maintain the vehicles paint finish from the time of arrival at the dealership until retail delivery to the customer. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.
