- Step 1
Look at your dashboard before putting the key in the ignition.
- Step 2
Turn the key to the on position (not the start position) without taking your eyes off the dash lights. All the lights should light up for five or more seconds so you can check that they're working.
- Step 3
Note that the gauges (the gas gauge, temperature gauge, and possibly a charge indicator gauge instead of a battery light) can only be checked when the engine is running.
- Step 4
Visit your mechanic if you notice that one of the lights is no longer coming on.
