Mazda 6 Owners Manual: Fuel Gauge
The fuel gauge shows approximately how much fuel is remaining in the tank when the ignition is switched ON. We recommend keeping the tank over 1/4 full.
If the fuel level is low,

turn an amber color. Refuel as soon as possible.
Refer to Taking Action.
NOTE
- After refueling, it may require some time for the indicator to stabilize. In addition, the indicator may deviate while driving on a slope or curve since the fuel moves in the tank.
- The display indicating a quarter or less remaining fuel has more segments to show the remaining fuel level in greater detail.
- The direction of the arrow
indicates
that the fuel-filler lid is on the left side of the vehicle.
