491-2. Child safety
1
For safety and security
tion
 Raise the seatback as much as pos-
sible
 Raise the seat to the highest position
 If the head restraint interferes with
the installation of the child restraint
system, and the head restraint can
be removed, remove the head
restraint
If the head restrain t cannot be removed,
raise it to the uppermost position.
WARNING
■When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●Never install a re ar-facing child
restraint system on the front passenger
seat even if the “AIR BAG OFF” indi-
cator light is illuminated. In the event of
an accident, the force of the rapid infla-
tion of the front passenger airbag can
cause death or serious injury to the
child if the rear-facing child restraint
system is installed on the front passen-
ger seat.
●A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable. A
child restraint system that requires a
top tether strap should not be used in
the front passenger se at since there is
no top tether strap anchor for the front
passenger seat.
●A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, raise the seatback as much as
possible, move the seat to the
rearmost position, and raise the seat to
the highest position, even if the “AIR
BAG OFF” indicator light is illumi-
nated.
If the head restraint interferes with the
installation of the ch ild restraint system,
and the head restraint can be removed,
remove the head restraint.
If the head restraint cannot be removed,
raise it to the uppermost position.

with a metallic object
●If the key is in close proximity to or touch-
ing a key registered to the security sys-
tem (key with a built-in transponder chip)

Never leave the keys inside the
vehicle when you leave the vehicle.
This system is designed to help pre-
vent vehicle theft but does not

Vehicle status information and indicators
speed, a ring-shaped indicator will be
displayed on the tachometer.
The desired engine speed at which the Rev
indicator will begin to be displayed can be
set on of the multi-information display.
(  P.79)
■Rev peak (F SPORT models)
The engine speed reaches or exceeds
5000 rpm, an afterimage of the
tachometer will be displayed at the
highest engine speed for approxi-
mately 1 second.
■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.
■Liquid crystal display
Small spots or light sp ots may appear on the
display. This phenomenon is characteristic
of liquid crystal disp lays, and there is no
problem continuing to use the display.
■Customization
The gauges and meters can be customized
on of the multi-in formation display.
( P.83)
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 information 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.426)
