My owners book says 6.6 gallons.
The miles to empty display said I had about 46 miles to go before empty. At fill up, I put 5.6 gallons in. Which means I had about a gallon left, so, yes about 46 miles to empty. According to the average mpg the display shows, I am averaging about 48 to 50 mpg. All the numbers add up correctly and make sense. I didn't write anything down and get into heavy math, just a quick think through while filling the tank. Also, the book says the Low Fuel light comes on with about 1.9 gallons remaining. Thats a range of about 90 miles on low fuel. Not bad.
