When the gas light on a 2004 Toyota Camry comes on, it typically indicates that there are around 2 gallons of fuel left in the tank. This gives the driver approximately 30-40 miles of driving range. However, this range can vary depending on the driving conditions and fuel efficiency of the vehicle. For example, if the vehicle is driven in stop-and-go traffic or in an area with hills, the range may be reduced.
It's important to note the remaining range will vary depending on several factors, including your recent fuel consumption patterns and your driving conditions. To ensure safety, it's recommended to refuel as soon as possible when the fuel light turns on.
