Fuel Gauge The fuel gauge The fuel gauge displays approximately how much fuel is in the fuel tank only when the ignition switch is ON. For proper fuel gauge indication after adding fuel, turn the ignition switch OFF while refueling the vehicle. The fuel gauge indicator may vary slightly when the vehicle is in motion. The most accurate reading is obtained with the vehicle on level ground. With ignition switch OFF, the fuel gauge indicator may drift from the ignition switch ON position. When you turn the ignition key to the ON or ACC position, all the display segments will light up, then go off for a second indicating the gauge is working. Then the gauge will show you how much fuel you have in the tank. Engine Coolant Temperature Gauge This gauge indicates the temperature of the engine coolant, not the coolant level. If the coolant is not at its proper level or mixture, the gauge indication will not be accurate. 17

Fuel Gauge
The fuel gauge
The fuel gauge displays approximately how
much fuel is in the fuel tank only when the
ignition switch is ON. For proper fuel gauge
indication after adding fuel, turn the ignition
switch OFF while refueling the vehicle.
The fuel gauge indicator may vary slightly when
the vehicle is in motion. The most accurate
reading is obtained with the vehicle on level
ground.
With ignition switch OFF, the fuel gauge
indicator may drift from the ignition switch ON
position.
When you turn the ignition key to the ON or
ACC position, all the display segments will light
up, then go off for a second indicating the gauge
is working. Then the gauge will show you how
much fuel you have in the tank.
Engine Coolant Temperature Gauge
This gauge indicates the temperature of the
engine coolant, not the coolant level. If the
coolant is not at its proper level or mixture, the
gauge indication will not be accurate.
