Fuel Gauge
The fuel gauge shows how much
fuel the vehicle has left while the
engine is on.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.
When the needle approaches the
low fuel symbol, a chime sounds
and LOW FUEL appears on the
Driver Information Center (DIC)
display. There is still a little fuel left,
but the vehicle's fuel tank should
be filled soon.Press the RESET button to
acknowledge a DIC message(s).
Pressing the RESET button also
turns off a DIC message but the
LOW FUEL message comes on
again in 10 minutes if fuel is not
added to the vehicle.
Here are five things that some
owners ask about. All these things
are normal and do not indicate
that anything is wrong with the
fuel gauge.
.At the service station, the gas
pump shuts off before the gauge
reads the full.
.It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated half
full, but it took a little more or
less than half of the tank's
capacity to fill the tank.
.The gauge pointer may move
while cornering, braking or
speeding up.
.The gauge may not indicate the
tank is empty when the ignition
is turned off.
.The gauge reading may change
slightly within the first several
minutes after starting the
vehicle.

in Driver Information Center (DIC)

.The engine coolant temperature
is higher than 76°C (169°F).
.The vehicle is going 24 to
31 km/h (15 to 19 mph).
.The vehicle is at 21 percent
