'06 AVALON_U (L/O 0508) Tachometer Your vehicle may overheat during severe operating conditions, such as: Odometer and two trip meters D Driving up a long hill on a hot day. D Reducing speed or stopping after high speed driving. D Idling for a long period with the air conditioning on in stop- and- go traffic. D Towing a trailer. NOTICE z Do not remove the thermostat in the engine cooling system as this may cause the engine to overheat. The thermostat is designed to control the flow of coolant to keep the temperature of the engine within the specified operating range. z Do not continue driving with an overheated engine. See "If your vehicle overheats" on page 312 in Section 4. The tachometer indicates engine speed in thousands of rpm (revolutions per minute). Use it while driving to select correct shift points and to prevent engine lugging and over- revving. Driving with the engine running too fast causes excessive engine wear and poor fuel economy. Remember, in most cases the slower the engine speed, the greater the fuel economy. This meter displays the odometer and two trip meters when the ignition switch is set at ON. 1. Odometer-Shows the total the vehicle has been driven. distance 2. Two trip meters-Show two different distances independently driven since the last time each trip meter was set to zero. You can use one trip meter to calculate the fuel economy and the other to measure the distance on each trip. All trip meter data is cancelled if the electrical power source is disconnected. NOTICE Do not let the indicator needle get into the red zone. This may cause severe engine damage. 143
