It is the dealer's responsibility to maintain the specified State-Of-Charge (SOC) of the vehicle's battery while in stock and ensure proper SOC at delivery. To eliminate customer service concerns due to an undercharged battery during the first few weeks of ownership, ALL dealers should check battery SOC and recharge, if necessary, within 48 hours of delivery to customers.

If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: Minor damage: requires only buffing to repair. Moderate damage: usually requires neutralizing, color sanding, and buffing. Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. While the quality and durability of paint on Lexus vehicles is continuously being improved, it remains the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

wheels, exposure to heavy machinery facilities, grinding, welding, etc. This type of contamination can be identified by the presence of small, red or brown particles on the paint surface. These particles are often difficult to see on dark color paints but can be easily felt when brushing a hand across horizontal body surfaces such as the hood, roof, or deck lid. Follow the Repair Procedure in this bulletin to clean vehicles that may have been subjected to contamination by airborne iron particles such as rail dust during rail transportation or extended storage near industrial areas.

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.

Be sure to review the entire content of this service bulletin before proceeding. This Service Bulletin provides best practice procedures for vehicle pulling complaint, diagnosis, and repair for 2002 ? 2021 model year Lexus vehicles. This information supplements Repair Manual procedures when the symptoms are: ?Vehicle Pulling: The vehicle moves to the right or left when the driver holds the steering wheel while driving straight ahead without exerting steering effort. ?Steering Wheel Off Center: The vehicle travels straight, but the steering wheel is not pointed straight ahead. The vehicle is not pulling. Before repairing a vehicle pulling to one side, it is necessary to clearly identify the cause of the pulling condition. Frequently, pulling to one side is diagnosed as a wheel alignment concern. However, the actual cause may be related to the lateral force generated by the tires, vehicle damage, road crown or worn components. Performing a wheel alignment when tire force is the cause could result in the wheel alignment being set at a value outside of specifications. This could then cause other problems such as uneven tire wear, etc. A customer may notice a pull to the left when in the left lanes of travel and notice a pull to the right or no pull when traveling in the right lanes of travel on the very same section of roadway. This road crown effect is environmental and cannot be corrected with suspension adjustments or any other wheel or tire modification discussed in this bulletin.
