TACHOMETER
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine overrevving.
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.
It is not a malfunction even if the needle of the tachometer
returns to the bottom position when the ignition switch is turned
to the “START” position.
NOTICE
Do not let the indicator needle get into the red zone. This
may cause severe engine damage.
ODOMETER AND TRIP METER
 Trip meter reset knob
This meter displays the odometer and two trip meters. To
change the mode indication, push the trip meter reset
knob briefly. Each time you push the knob, the mode
changes in order from the odometer to trip meter A to trip
meter B, then back to the odometer, etc.
The odometer records the total distance the vehicle has
been driven. The twin trip meter records two different
distances independently.
For example, you can use one meter to calculate the fuel
economy and the other to measure the distance on each trip.
To set the A trip meter to zero, display the A meter reading,
push the knob and hold it. The same applies for the B trip
meter.
The data of trip meters will be cancelled if the electrical power
source is disconnected.

54The multiinformation display provides various
information, including clock, outside temperature, and
your vehicle’s driving condition.
When the ignition switch is on, the last previously used mode
displayed just before the ignition switch is off will appear.
If the electrical power source has been disconnected from the
multi−information display, the
display will automatically be set
to the initial mode.
When the instrument panel lights are turned on, the brightness
of the display will be reduced.
You can adjust the brightness of the display. To adjust the
brightness, see “ADJUSTING THE BRIGHTNESS OF THE

Outside temperature mode
In outside temperature mode, outside air temperatures
are displayed.
The displayed value is updated every 1 second.
The displayed temperature ranges from −22F (− 30C) up to
122 F (50C).
If there is some abnormality in the connection of the outside air
temperature sensor, “ −−” will appear on the display. If “ −−”
appears on the display, contact your Lexus dealer.
In some cases, “ −−” may appear momentarily when the ignition
is quickly turned to “ON”. It is normal if it goes out soon. 
Average fuel consumption modeAverage fuel consumption is calculated and displayed
based on total driving distance and total fuel consumption
with the engine running.
The displayed value is updated every 10 seconds.
To reset the calculations, push and hold the “RESET” button for
more than 1 second.

Instantaneous fuel consumption mode
Instantaneous fuel consumption is calculated and
displayed based on distance and fuel consumption for 2
seconds with the engine running.
The displayed value is updated every 2 seconds.
Note that an accurate figure may not be shown in the following
cases.
 When the vehicle is stopped with the engine running, the
display will indicate extremely high fuel consumption.
 When the vehicle is driving down a long slope, with the
engine brake applied, the display will indicate extremely low
fuel consumption.
To reset the calculations, push and hold the “RESET” button for
more than 1 second. 
Driving range modeThe distance the vehicle can travel with the remaining fuel
is calculated and displayed based on the quantity of
remaining fuel and past fuel consumption.
The driving range display indicates the approximate distance
that you can drive until the fuel gauge reaches “E”. It is dif ferent
from the actual distance traveled.
The displayed value is updated every time the fuel required to
travel 0.6 miles (1 km) is consumed.
Every time you refuel the vehicle, the calculation is reset.
The actual driving range varies with driving habits and road
conditions. If fuel consumption is good, the driving range will
be longer. If fuel consumption is poor, the driving range will be
shorter.
If the low fuel level warning light comes on, refuel even if the
display indicates that the vehicle can be driven further.

Average vehicle speed mode
Average vehicle speed is calculated and displayed based
on total driving distance and total driving time with the
engine running.
The displayed value is updated every 10 seconds.
To reset the calculations, push and hold the “RESET” button for
more than 1 second. 
Barometer modeIn barometer mode, the atmospheric pressure in the
vehicle is displayed.
The displayed atmospheric pressure ranges from 17.8 IN.HG
(600 hPa) up to 31.0 IN.HG (1050 hPa).
The displayed value is updated every 2 seconds.
The displayed value may deviate from the actual atmospheric
pressure depending on opening or closing of the windows and
doors and the driving conditions.

Altimeter mode
In altimeter mode, the approximate altitude is displayed.
The displayed altitude ranges from −1500 ft. (−500 m) up to
13000 ft. (4000 m).
As the altitude value is converted from the atmospheric
pressure, it can be easily affected by air motion and
temperature, so the indication may vary. The indicated altitude
of a single position may deviate according to the atmospheric
pressure and temperature.
The displayed value is updated every 2 seconds.
RECTIFICATION OF THE ALTITUDE
Rectification is valid only when the correct altitude is known.
While the altitude mode is on the display, push the “
” or “”
button to increase or decrease the altitude by 50 ft. (10 m).
To reset the rectified altitude, push and hold the “RESET”
button for more than 1 second. 
Elapsed time mode
The time that has elapsed since the engine started is
displayed.
When the engine is started, driving time is counted from 0:00.
Up to 19:59 (19 hours, 59 minutes) can be displayed. When
the driving time exceeds 19:59, the counter returns to 0:00.
To reset the calculations, push and hold the “RESET” button for
more than 1 second.
