2009 Cadillac STS-V Owner's Manual - Page 211

Speedometer and Odometer The speedometer shows the speed in both miles per hour (mph) and kilometers per hour (km/h). See "MPH (km)" under DIC Operation and Displays on page 3-72 for more information. The odometer mileage can be checked without the vehicle running. The vehicle's odometer works together with the driver information center. The odometer can be set for a Trip A and a Trip B. See "Trip Information" under DIC Operation and Displays on page 3-72 for more information. If the vehicle ever needs a new odometer installed, the new one will be set to the correct mileage total of the old odometer. Safety Belt Reminders Driver Safety Belt Reminder Light When the engine is started, a chime sounds for several seconds to remind the driver to fasten the safety belt, unless the driver's safety belt is already buckled. The driver safety belt light comes on and stays on for several seconds, then flashes for several more. Tachometer This gage indicates the engine speed in revolutions per minute (rpm). This chime and light are repeated if the driver remains unbuckled and the vehicle is in motion. If the driver's safety belt is already buckled, neither the chime nor the light comes on. 3-57
