Multi Display of LEXUS IS250
Various information is showed on the multi display. Concretely, it is displayed such as outdoor temperature, cruising range, average fuel efficiency, average fuel efficiency after refueling, moment fuel efficiency, average velocity, gear condition and nothing. These indications are changed by switch on steering.
Outdoor Temperature
It shows outdoor temperature. measurable temperature is from -40 to 50 degree C. Recently it is natural to equip the thermometer for car. It was not natural that the thermoneter was equip for car long ago. I got into a habit to confirm the temperature every moring. I think this is basic function but very useful. By the way, this this indication turn on onad off when temperature become below 3 degree C.
Cruising Range
It shows rough estimate cruising range calculated by residual fuel. It is not sure cruising range because this range is calculated based on average fuel efficiency. In my experience, empty lump lights when residual fuel become about 10 litter. At this time, this indication shouws about 60 km. When this indication shows 0 km, the residual fuel is about 5 litter. This is just for your information!
Average Fuel Efficiency
It shows average fuel efficiency after reset. The way of reset is to push the DISP switch long time during showing average fuel efficiency. I have never reset after purchasiung this car. This indication of my car show average fuel efficiency after purchasing my car. At thi present (Feb. 2012), this indication shows 11.8 km/L. I don't know this fuel efficiency is good or not surely. I think ,however, this average fuel efficiency for car with 2.5 L engine. I feel strange for average fuel efficiency, because it is caluculated 10.8 km/L by full tank fuel method. The difference between indication and calculated value. I don't know why.
Average Fuel Efficiency after Refueling
It shows average fuel efficiency after refueling. I usually use this indication. It is easily changed by operation of accelerator pedal at the moment after refueling. I am concious of ecological driving when I look this indication. I propose that a government obligate to equip this indication for all cars. Most of people will be concious of ecology. This wasy will be very effective.
Moment Fuel Efficiency
It shows moment fuel efficiency. As you know, moment fuel efficiency is getting increase if you are off accelerator and is getting decrease if you are on accelerator. It rare for me to use this indication. I sometimes confirm my driving by looking this indication when I drive my car. I learned that acceleration at start affect to fuel efficiency sgnificantly. I have heard that most effective acceleration is that it is accerarate to 20km/h for 5 seconds. I felt this way of acceleration is too slow for most of drivers. You had better to mention the driver at your back if you accelaerate slowly.
Average Velocity
It shows average velocity after ignition on or reset. The way of reset is to push the DISP switch long time during showing average velocity. Practicaly, this indication shows almost same value when you drive high way or country road. In urban, it shows slmost half value. It is useful to forsee the estimate arrial time.
Gear Condition
It shows gear position at you use D range or S range. The actual gear position indicated as number and the allowance gear position incdicated as dot.
Nothing
If you would not like to indicate anything, you can select nothing. As likely not to display nvigation sisutemu, you can indicate nothing to multi display. I usually use average fuel efficiency after refueling. When the fuel become near empty, I use cruising range. I sometimes use average velocity for calculating the estimate arrival time. What kind of indication do you use?
