The speedometer shows the vehicle's speed in either kilometers per hour (km/h) or miles per hour (mph).
Odometer
The odometer shows how far the vehicle has been driven, in either kilometers or miles.
Trip Odometer
The trip odometer shows how far the vehicle has been driven since the trip odometer was last reset.
The trip odometer is accessed and reset through the Driver Information Center (DIC). See Driver Information Center (DIC).
Tachometer
The tachometer displays the engine speed in revolutions per minute (rpm).
For vehicles with the Stop/Start system, when the ignition is on, the tachometer indicates the vehicle status. When pointing to AUTO STOP, 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.
