Lexus RZ 300E Maintenance in Phoenix Heat
- Test the RZ 300E battery before every summer, and replace it proactively around the 3-year mark
- Follow the severe-service schedule for oil and fluids, since Phoenix heat and traffic count as severe use
- Inspect RZ 300E brakes and tires twice a year; heat and stop-and-go driving wear both quickly
- Check coolant level and condition, and inspect belts and hoses for cracking
- Service the A/C early; a weak system rarely fixes itself
