The instrument panel shows the fuel gauge at all times.
Remaining fuel
The fuel meter indicates the amount of fuel left in your vehicle's tank. When the vehicle's tank is low on fuel, the fuel pump symbol changes color.
The meter also displays an estimated fuel range for how much further you can drive before the tank is empty. This range is calculated by the trip meter based on your average fuel consumption over the last 30 km (20 miles) and how much fuel is left in the tank. When you can see a dotted line instead of a range, it means that there isn't enough remaining fuel to calculate the range and you should refuel as soon as possible.
Note
Your driving style can have different effects on the estimated fuel range.
