Low fuel level warning light
The gauge indicates the approximate quantity of fuel
remaining in the tank when the engine switch is selected
in “IGON” mode.
It is a good idea to keep the tank over 1/4 full.
If the fuel level approaches ”E” 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.

TEMPERATURE GAUGE
G13002
 Normal range

engine operating temperature will vary with changes in
weather and engine load.
If the needle points to the red zone or higher, stop your vehicle
and allow the engine to cool.
Your vehicle may overheat during severe operating conditions,
such as:
 Driving up a long hill on a hot day.
 Reducing speed or stopping after high speed driving.
