2010 RX 350 and RX 450h UPDATED MAINTENANCE REQUIREMENTS Important Supplement to Your Warranty and Services Guide SAFETY PRECAUTIONS The RX 450h is a gas/electric hybrid vehicle that has both high-voltage DC and AC systems as well as a 12-volt system. Both DC and AC high voltage are very dangerous and can cause personal injury, severe burns, electric shock and even fatal injury unless appropriate precautions are taken. To avoid personal injury, please follow all caution labels attached to highvoltage parts. Do not touch or attempt to remove or replace any high-voltage (orange-colored) wiring and connectors. Do not touch the service plug behind the trim under the left rear seat. If an accident occurs, do not touch any high-voltage wiring, connectors or parts such as the inverter under the hood or the hybrid battery assembly under the rear seat. Do not touch the potassium hydroxide electrolyte that might spill or leak from the hybrid battery as the result of an accident. If potassium hydroxide electrolyte gets on your skin or in your eyes, neutralize it immediately with a saturated boric acid solution (ratio: 80 grams boric acid to two liters water). Seek immediate medical attention. If a vehicle fire occurs, extinguish it with a Class D powder-type fire extinguisher. IMPORTANT NOTICE This booklet replaces the "Scheduled Maintenance Log" section of the Warranty and Services Guide in your glove box. Please refer to the booklet you are now reading for information on scheduled maintenance requirements for your vehicle. The "Scheduled Maintenance Log" section of the Warranty and Services Guide no longer applies to your vehicle. Introduction 1 MAINTENANCE BASICS MAINTENANCE IS ESSENTIAL Regular maintenance is essential to obtaining the highest level of performance, safety and reliability from your Lexus. It can also enhance your vehicle's resale value. It is especially important to check your vehicle's engine oil once a month and to regularly replace the engine oil and oil filter. Failure to do so can cause oil starvation and/or oil gelling, which can result in severe damage to your vehicle and require costly repairs that are not covered by the New Vehicle Limited Warranty. Lexus recommends having maintenance for your vehicle performed by an authorized Lexus dealership. To locate your nearest authorized Lexus dealership, contact Lexus Customer Satisfaction at (800)255-3987 or visit www.lexus.com. DETERMINING YOUR MAINTENANCE INTERVAL: MONTHS VS. MILEAGE Lexus recommends obtaining maintenance for your vehicle every six months or 5,000 miles, whichever comes first. For example: · If at six months you have driven less than 5,000 miles, you should obtain maintenance at six months; don't wait until 5,000 miles. · If you drive 5,000 miles in less than six months, you should obtain maintenance at 5,000 miles; don't wait until six months. Be sure to keep an eye on your mileage so that you obtain maintenance when recommended. If you are a lowmileage driver, mark your calendar to remind yourself to obtain maintenance every six months. 2 Introduction SPECIAL OPERATING CONDITIONS In addition to standard maintenance items, vehicles that are driven under special operating conditions require further maintenance service. These special operating conditions, which put added demands on a vehicle, include: · Driving off-road, on dirt roads or on dusty roads · Towing a trailer, using a car-top carrier or heavy vehicle loading · Repeated trips of less than five miles in temperatures below 32° F or 0°C · Extensive idling and/or lowspeed driving for long distances, such as police, taxi or door-todoor delivery use If you drive primarily under any of the conditions noted above, you should replace the engine oil and oil filter every six months or 5,000 miles. Some of these special operating conditions require other maintenance items; these items are indicated in each maintenance chart. Note: If you drive only occasionally under any of the special operating conditions noted, it is not necessary to change the oil every six months or 5,000 miles or to perform the additional services listed in the charts. This added maintenance is required only if you drive primarily under any of the special operating conditions.
