The owner's manual for my car (95 ES300) has 2 maintenance schedules, A and B. Schedule A is for tough driving conditions (sandy area, lots of idling, towing heavy loads, etc.) Schedule B is for normal driving. I drive mostly on the highway, so I'm definitely on B.
The "timing belt" entry in the schedule says "only for maintenance schedule A", and then gives the mileage for that schedule at which it should be replaced.
I'm now at 105,000 miles, and I'm wondering if the timing belt should be replaced. I believe that it was replaced by the previous owner at 60,000.
Thanks!
