Buick Regal: Speedometer
The speedometer shows the vehicle's speed in either kilometers per hour (km/h) or miles per hour (mph).
Odometer
The odometer shows how far the vehicle has been driven, in either kilometers or miles.
Tachometer
The tachometer displays the engine speed in revolutions per minute (rpm).
For vehicles with the Stop/Start system, when the ignition is on, the tachometer indicates the vehicle status. When pointing to AUTO STOP, the engine is off but the vehicle is on and can move. The engine could auto start at any time.
When the indicator points to OFF, the vehicle is off.
When the engine is on, the tachometer will indicate the engine's revolutions per minute (rpm). The tachometer may vary by several hundred rpm's, during Auto Stop mode, when the engine is shutting off and restarting.
A slight bump may be felt when the transmission is determining the most fuel efficient operating range.
Caution: If the engine is operated with the rpm's in the warning area at the high end of the tachometer, the vehicle could be damaged, and the damage would not be covered by the vehicle warranty. Do not operate the engine with the rpm's in the warning area.
Fuel Gauge

When the ignition is on, the fuel gauge indicates about how much fuel is left in the tank.
An arrow on the fuel gauge indicates the side of the vehicle the fuel door is on.
When the indicator nears empty, the low fuel light comes on. There is still a little fuel left, but the fuel tank should be filled soon.
Here are four things that some owners ask about. None of these show 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 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.
