Fuel Gauge

When the ignition is on, the fuel gauge shows about how much fuel the vehicle has left in the fuel tank. An arrow on the fuel gauge indicates the side of the vehicle the fuel door is on.

The gauge will first indicate empty before the vehicle is out of fuel and the low fuel light comes on, but the vehicle's fuel tank should be filled soon.

Here are some situations that can occur with the fuel gauge. None of these indicate a problem with the fuel gauge.

○ At the service station, the fuel pump shuts off before the gauge reads full.
○ It takes a little more or less fuel to fill up than the gauge indicated. For example, the gauge may have indicated the tank was half full, but it actually took a little more or less than half the tank's capacity to fill the tank.
○ The gauge moves a little while turning a corner or speeding up.
○ The gauge takes a few seconds to stabilize after the ignition is turned on, and goes back to empty when the ignition is turned off.
