2009 Cadillac CTS-V Owner's Manual - Page 183

Charging System Light This light comes on briefly when the ignition key is turned to START, but the engine is not running, as a check to show it is working. Up-Shift Light The vehicle may have an up-shift light, it shows when to shift to the next higher gear for best fuel economy. If it does not, have the vehicle serviced by your dealer/retailer. The light should go out once the engine starts. If it stays on, or comes on while driving, there could be a problem with the charging system. A charging system message in the Driver Information Center (DIC) can also appear. See DIC Warnings and Messages on page 3-57 for more information. This light could indicate that there are problems with a generator drive belt, or that there is an electrical problem. Have it checked right away. If the vehicle must be driven a short distance with the light on, turn off accessories, such as the radio and air conditioner. See Manual Transmission Operation on page 2-42 for more information. For the CTS-V, the tracer lights function as a performance up-shift light. These tracers flash to indicate when to shift to the next higher gear to avoid the engine speed limit. See Automatic Transmission Operation on page 2-37 or Manual Transmission Operation on page 2-42 for more information. 3-37
