5-12 Instruments and Controls Speedometer The speedometer shows the vehicle's speed in either kilometers per hour (km/h) or miles per hour (mph). 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. 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. If the vehicle needs a new odometer installed, the new one is set to the mileage of the old odometer. If this is not possible, it is set at zero and a label is put on the driver door to show the old mileage reading. Metric English
