when you start the engine, this could
mean that these systems are not available

could result in death or serious injury.
Have the vehicle inspected by your
Lexus dealer immediately if this occurs. Indicators Turn signal indicator ( → P.169)

Outside temperature display●
In the following situations, the correct
outside temperature may not be dis-
played, or the display may take longer
than normal to change:
• When stopped, or driving at low speeds
(less than 12 mph [20 km/h])
• When the outside temperature has
changed suddenly (at the entrance/exit of
a garage, tunnel, etc.)●
When “--” or “E” is displayed, the system
may be malfunctioning. Take your vehicle
to your Lexus dealer.■
Liquid crystal display

Customization
The gauges and meters can be customized
on of the multi-information display.
( → P.81) ■
Display items
 Odometer Displays the total distance the vehicle has
been driven.
 Trip meter A/trip meter B Displays the distance the vehicle has been
driven since the meter was last reset. Trip
meters A and B can be used to record and
display different distances independently.
 Distance until next engine oil
change Displays the distance the vehicle can be
driven until an oil change is necessary. ■
Changing the display
Each time the “ODO TRIP” switch is
pressed, the displayed item will be
changed. When the trip meter is dis-
played, pressing and holding the switch
will reset the trip meter.WARNING■
The information display at low tem-
peratures
Allow the interior of the vehicle to warm
up before using the liquid crystal infor-
mation display. At extremely low tem-
peratures, the in formation display
monitor may respond slowly, and display
changes may be delayed.
For example, there is a lag between the
driver’s shifting and the new gear number
appearing on the display. This lag could
cause the driver to downshift again,
causing rapid and excessive engine brak-
ing and possibly an accident resulting in
death or injury.
NOTICE
■
To prevent damage to the engine and
its components
●
Do not let the indicator needle of the
tachometer enter the red zone, which
indicates the maximum engine speed. ●
The engine may be overheating if the
engine coolant temperature gauge is
in the red zone (H). In this case, imme-
diately stop the vehicle in a safe place,
and check the engine after it has
cooled completely. ( → P.443)
