■The meters and display illuminate when
The engine switch is in IGNITION ON
mode.
■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.
■Pop-up display
●In some situations, su ch as when a switch

Vehicle status information and indicators
■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.
■Pop-up display
Distance until the next engine oil
change will displayed when a warning
message indicating that oil mainte-
nance should be performed soon or is
required is displayed.
The brightness of the instrument panel
lights can be adjusted.
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.365)

■Cautions during setting up the dis-
play
As the engine needs to be running
during setting up the display, en sure that
the vehicle is parked in a place with ade-
quate ventilation. In a closed area such as
a garage, exhaust gases including harm-
ful carbon monoxide (CO) may collect
and enter the vehicle. This may lead to
death or a serious health hazard.
NOTICE
■During setting up the display
To prevent battery discharge, ensure that
the engine is running while setting up the
display features.

■Card key (if equipped)
●The card key is not waterproof.
●The mechanical key that is stored inside
the card key should be used only if a
problem arises, such as when the card key does not operate properly.
●If it is difficult to take out the mechanical
key, push down the lock release button
using a pen tip etc. If it is still difficult to
pull it out, use a coin etc.
●To store the mechanical key in the card
key, insert it while pressing the lock

aircraft, make sure you do not press any
buttons on the electronic key while inside
the aircraft cabin. If you are carrying an
electronic key in your bag etc., ensure that
the buttons are not likely to be pressed acci-
dentally. Pressing a button may cause the
electronic key to emit radio waves that
could interfere with the operation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
(The card key battery life is about a year
and a half.)
