Instruments and Controls 5-11 Speedometer The speedometer shows the vehicle's speed in either kilometers per hour (km/h) or miles per hour (mph). The trip odometer is accessed and reset through the Driver Information Center (DIC). See Driver Information Center (DIC) on page 5￿25 for more information. A slight bump may be felt when the transmission is determining the most fuel efficient operating range. Fuel Gauge Odometer The odometer shows how far the vehicle has been driven, in either kilometers or miles. This vehicle has a tamper￿resistant odometer. The digital odometer will read 999,999 if it is turned back. If the vehicle needs a new odometer installed, it must be set to the mileage total of the old odometer. If that is not possible, then it must be set at zero and a label must be put on the driver door to show the old mileage reading when the new odometer was installed. Tachometer The tachometer displays the engine speed in revolutions per minute (rpm). For eAssist vehicles, when the ignition is in ON/RUN, the tachometer indicates the vehicle status. When pointing to AUTO, 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. When the ignition is on, the fuel gauge shows 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 vehicle's fuel level becomes low, a message appears in the Driver Information Center Trip Odometer The trip odometer can show how far the vehicle has been driven since the trip odometer was last reset.
