TSB: On some vehicles, when Rapgard is removed, the paint may have a stained appearance. These stains appear to be under the clear coat (repainting this area is not necessary). The stain patterns are usually under wrinkles in the Rapgard. These wrinkles sometimes trap water and cause the paint to stain from the trapped moisture, especially on horizontal surfaces, such as the hood, roof, and trunk. Stains can be removed by heating the stained surface to remove the trapped moisture.

TSB: Flash reprogramming allows the ECU software to be updated without replacing the ECU. Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Techstream ECU flash reprogramming process and outlines use of the Technical Information System (TIS) and the Calibration Update Wizard (CUW). Flash calibration updates can only be applied to the vehicle/ECU combination for which they are intended. ECUs have internal security that will not allow them to be programmed with another ECU?s information.

TSB: Pre-Delivery Service (PDS) is a critical step in satisfying our new car customers. Customer feedback indicates the following areas deserve special attention when performing PDS: ? Careful inspection for paint chips/scratches and body dents/dings. ? Proper operation of electrical accessories (including interior light, clock, and radio reset). ? Interior cleanliness. ? Proper function of mechanical systems. Customer retention and proper maintenance of vehicles has been a major focus for Toyota. To help remind customers that regular oil changes are essential to the proper maintenance of their vehicle, installing a first oil change reminder sticker is required prior to delivery. By doing this, customers will be reminded to return to a dealership for their first oil change. Your current oil change reminder sticker may be used. (See PDS Check Sheet item 9 of "Final Inspection & Cleaning.")

TSB: As a result of the removal of the Short Pin, the power source to the steering angle sensor is cut off. When the Short Pin is reinstalled, the Parking Assist Monitor System will be operative, but it cannot display guidelines to assist parking operation because the center position is not recognized by the steering angle sensor. Please initialize the Parking Assist Monitor System after installing the Short Pin during Pre-Delivery Service (PDS).

Tech Tip: Starting with the 2010 Model Year, Toyota began a gradual transition to the use of synthetic 0w20 viscosity engine oil. There are multiple benefits of this oil including: Reduced friction and wear on engine surfaces, Improved fuel economy, Reduction in waste oil stream (in vehicles approved for 10,000 mile oil change intervals), Reduced maintenance cost (in vehicles approved for 10,000 mile oil change intervals). Due to the improved performance and durability of 0w20 synthetic oil, Toyota has extended the oil change intervals to 10,000 mile for most vehicles that require this oil. With this change, the following should be noted: The 2TR-FE (4Runner/Tacoma) and the 3UR-FBE (Flex Fuel Tundra/Sequoia) are the exceptions to this new change interval program; these engines have not been approved for the 10,000 mile interval at this time. A 5,000 mile oil change interval is still required for these vehicles. Also, the Flex Fuel 3UR-FBE requires a 2,500 mile interval when operated on E85 50% of the time or more. Only Toyota vehicles in which 0w20 oil is mandatory (except for the 2TR-FE & 3UR-FBE Engines) have been approved for extended oil change intervals. Vehicles in which 0w-20 is an option to 5w20 (or 5w30) will continue to require 5,000 mile change intervals, even if 0w20 oil is used. In case of vehicles with 10,000 mile oil change intervals, the 5,000 mile service interval has not been eliminated. The traditional 5,000 mile maintenance procedures (such as tire rotation) will continue to be required, and the fluid levels (including engine oil) will need to be checked and adjusted at this time. If the vehicle operation meets the standard criteria for "Special Operating Conditions" such as: driving off-road, on dirt roads, towing a trailer, making repeated short trips under 32 degrees F, or extensive idling, the engine oil must be replaced at 5,000 mile intervals, regardless of oil used.
