<human>:  My gas light just turned on. How far can I drive?
<bot>: It’s not recommended to drive any significant distance with the gas light on. You should get to a gas station and fill up right away. You can check gas levels with your gas gauge, and if it’s below half a tank you should get gas soon. Gas levels can also vary significantly depending on weather, vehicle load, and driving conditions. It’s a good idea to monitor your gas gauge regularly and carry an emergency fuel supply with you. As a precaution, you should plan trips to include sufficient fuel and alternate routes, and always have your vehicle serviced regularly.
