However, the Prius powers up a little differently than a conventional car, so there is always the possibility someone unfamiliar with the system might really screw things up while you’re at lunch. So in theory, you’d be fine servicing the car with the key in the slot, so long the car was power shut off. The engine will not start when the car is not “Ready”, which is the hybrid equivalent of KOER (Key On Engine Running). Like always, we’ll do the service however you want it done, but hopefully this will convince you to treat your Prius to a better service.īefore servicing a Prius, it’s a good practice to disable the Smart Key and remove it from the car. This page explains what we do during our version of the 30K & why. It also might be a good idea to balance the two tires rotated to the front with every service, so that every tire is balanced on a 10K schedule. We recommend that you replace the WS transaxle fluid, inverter coolant, ICE coolant, and flush the brake fluid in addition to the standard items. We feel that your Prius will last a lot longer if you do more than the skimpy service in the maintenance guide. It’s just some inspections, tire rotation (without balance), air filter, cabin filter, and an oil change & filter. The 2004-2009 Prius 30K service is a pretty small service if you only do the items listed in the Scheduled Maintenance Guide. It’s your car, and we’re happy to service it in any way you see fit. However, you can count on us having your best interest at heart. So, can you count on us always being right? No. The point is that there are many examples where we were right and they were wrong, and vice versa. Sometimes the manufacturer under-recommends based on engineering predictions. Sometimes we over-recommend based on past experience. Now that we know, we recommend replacing Toyota SLLC at 100K at then every 50K thereafter. Both groups didn’t have coolant related engine damage. Some people followed our recommendation, and some didn’t. We didn’t know that the new coolants were more than marketing hype until the “experiment” was over. We made our recommendation based on years of experience, and at the time we thought we were doing the right thing for our customers. Back then we didn’t know that the new coolant would actually protect the engine for up to 150K miles. Before these new coolants were developed, coolant did need to be replaced every 30K to prevent engine damage.
Toyota Super Long-Life Coolant (SLLC) was introduced in 2004, replacing Toyota’s Long-Life Coolant (LLC). Someone recently pointed out that we recommend replacing the coolant every 30,000 miles in this article, which isn’t our recommendation these days.
