58 Instruments and controls Cruise control indicator light This light comes on when the system is engaged. Indicator, fuel This light comes on when there is less than about 2.5 gallons (10 litre) of fuel left in the tank. NOTICE If the car runs out of fuel, air can be drawn in with the fuel, which, in turn, can cause the catalytic converter to be damaged by overheating. Shift-up (US-spec. cars only) This symbol can be found in cars with manual transmission. The symbol is not activated until the engine is warm. It is not always necessary or even recommended to shift up to a higher gear when this symbol lights up, such as when driving in heavy traffic or down a steep hill. Changing up a gear when the symbol comes on does however improve fuel economy. Make it a habit to shift up when the symbol lights up. Headlight and parking light indicator This light indicates that the headlights or parking lights are on. Autochecking of lights, main instrument panel The warning and indicator lights shown above should come on when the ignition switch is turned to ON. They should go out after about 4 seconds once the engine has started or after the fault-free self-diagnosis of each system or function.
