0_OM_(U)_1810outside 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
operation is performed, a pop-up display
will be temporarily displayed on the
multi-information display or the odome-
ter/trip meter screen (F SPORT models).
●Some pop-up displays can be set on/off.
(  P.76)
■Customization
The meter display can be customized on
the multi-information display. ( P.339)
■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 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 num-
ber appearing on the display. This lag
could cause the driver to downshift
again, causing rapid and excessive
engine braking and possibly an accident
resulting in personal 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.309)

Driving
Cargo capacity depends on the total
weight of the occupants.
(Cargo capacity) = (Total load capac-
ity) — (Total weight of occupants)
Steps for Determining Correct Load
Limit —
(1) Locate the statement “The com-
bined weight of occupants and cargo
should never exceed XXX kg or XXX
lbs.” on your vehicle’s placard.
(2) Determine the combined weight of
the driver and passengers that will be
riding in your vehicle.
(3) Subtract the combined weight of
the driver and passengers from XXX
kg or XXX lbs.
(4) The resulting figure equals the
available amount of cargo and luggage
load capacity.
For example, if the “XXX” amount
equals 1400 lbs. and there will be five
150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is 650 lbs. (1400 - 750
(5  150) = 650 lbs.)
(5) Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not safely
exceed the available cargo and lug-
NOTICE
●RC300: Make sure to idle the engine
immediately after high-load driving.
Stop the engine only after the turbo-
charger has cooled down.
Failure to do so may cause damage to
the turbocharger.
■If you get a flat tire while driving
A flat or damaged ti re may cause the fol-
lowing situations. Hold the steering
wheel firmly and gradually depress the
brake pedal to slow down the vehicle.
●It may be difficult to control your vehi-
cle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat
tire ( P.294)
■When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
the following serious damage to the vehi-
cle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water
immersion
In the event that you drive on a flooded
road and the vehicle is flooded, be sure
to have your Lexus dealer check the fol-
lowing:
●Brake function
●Changes in quantity and quality of oil
and fluid used for the engine, transmis-
sion, transfer (AWD models), differen-
tial, etc.
●Lubricant condition for the propeller
shaft, bearings and suspension joints
(where possible), and the function of
all joints, bearings, etc.

mation about storage precautions,
