FUEL GAUGE
SV13017

Low fuel level warning light
The gauge indicates the approximate quantity of the fuel
remaining in the tank when the ignition switch is on.
It is a good idea to keep the tank over 1/4 full.
If the fuel level approaches ºEº or the low fuel level warning light\
comes on, fill the fuel tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the fuel gauge needle may fluctuate or the low fuel level
warning light may come on earlier than usual.
If the fuel tank is completely empty, the malfunction indicator
lamp comes on. Fill the fuel tank immediately.The indicator lamp goes off after driving several times. If the
indicator lamp does not go off, contact your Lexus dealer as
soon as possible.
See the inner back cover for fuel capacity and recommended
fuel selection.

VOLTMETER
SV13021

1Discharge warning light 2Normal range
The voltmeter tells whether the battery is charged or
discharged. Check it while the engine is running ± the
needle should always indicate as shown above.
If the needle reads below or above the normal range while the
engine is running, it indicates that the charging system needs
immediate repair.
However, it is normal for the needle to drop below the normal
range during engine starting.
MOMENTARY FUEL CONSUMPTIONMETER

Vehicles sold in Canada

GAUGES, METERS AND SERVICE REMINDER INDICATORS
43
The momentary fuel consumption is calculated and
indicated based on the driving distance and the fuel
consumption with the engine running.
If you are driving at low speeds just before stopping, the
accurate figure may not be shown.
TACHOMETER
SV13016
The tachometer indicates engine speed in thousands of
rpm (revolutions per minute). Use it while driving to
prevent engine 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.
NOTICE
Do not let the indicator needle get into the red zone. This
may cause severe engine damage.

ODOMETER AND TRIP METER
SV13015
This meter displays the odometer and two trip meters. To
change the mode indication, push the ºODO/TRIPº 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 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.
