[The Critic]

Required maintenance on the RAV4 is as follows: Engine Oil and Filter replacement every 5k or six months, engine and cabin air filter replacement every 30k or three years, initial engine coolant replacement at 100k or ten years and spark plug replacement at 120k or 12 years.

The rear differential and transfer case oils need to be replaced every 30k or three years only if the vehicle is used for towing. Also, the front differential oil and transmission oil need to be replaced at 60k or six years if the vehicle is used for towing. Otherwise, the transmission fluid should be inspected every 30k and replaced on an as-needed basis (if fluid shows discoloration, sediment or unusual odor).
