Displays the engine speed in revolutions per minute
When sport mode is se lected for the driving mode, the periphery of the tachometer will
change color and the scale of the tachometer will be emphasized.

Displays warning messages if a malfunction occurs (P.436)
■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
 P.83
■Customization
The gauges and meters can be customized
on of the multi-information display.
(  P.87)
■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.449)

■Rev indicator
When the engine speed reaches a set
speed or the red zone, a ring-shaped
indicator ( ) will be displayed on the
tachometer.
The indicators will be displayed in amber
when the engine speed reaches a set
speed, and in red when the engine speed
reaches the red zone.
The engine speed at which the rev indica-
tor will begin to be displayed can be set on of the multi-information display.
(  P.87)
■Rev peak
When 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.
■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])

will be displayed on the meter.
To return to normal D position driving, the
“+” paddle shift switch must be held down
for a period of time.
A lower shift range will provide greater
engine braking forces than a higher shift
range.
■Automatic deactivation of shift range
selection in the D position
Shift range selection in the D position will
be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pedal is depressed for
more than a certain period of time
●When the shift position is shifted to a
position other than D.
●When pressing and holding the “+” pad-
dle shift switch
■Downshifting restriction warning
buzzer
To help ensure safety and driving perfor-
mance, downshifting operation may some-
times be restricted. In some circumstances,
downshifting may not be possible even
when the paddle shift switch is operated. (A
buzzer will sound twice.)
To enter M mode, shift the shift position
to M. Gears can be selected by oper-
ating the paddle shift switches, allowing you to drive in the gear of your choos-
ing.
Except F SPORT models
F SPORT models
1 Upshifting
2 Downshifting
The gear changes once every time the
paddle shift switch is operated.
The selected gear, from M1 to M10, will be
fixed and displayed on the meter.
When in the M position, the gear will
not change unless the paddle shift
switches are operated.
However, even when in the M position,
the gears will be automatically
changed in the following situations:
When vehicle speed drops (down-
shift only).
 When it is necessary to protect the
engine or automatic transmission
when the engine coolant tempera-
ture is low, the automatic transmis-
sion fluid temperature is high or low,
or other reasons.
Also, the gear will not shift when the
vehicle speed is low, even if an upshift
operation is performed.

4-6.Driving tips
Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
• Engine coolant
•Washer fluid
Have a service technician inspect
the condition of the battery.
 Have the vehicle fitted with four
snow tires or purchase a set of tire
chains for the rear tires.
*
Ensure that all tires are the specified size
and brand, and that chains match the size
of the tires.
*: Tire chains cannot be mounted on vehi-
cles with front and rear tires of differing
sizes.
Winter driving tips
Carry out the necessary prepara-
tions and inspections before driving
the vehicle in winter. Always drive
the vehicle in a manner appropriate
to the prevailing weather condi-
tions.
Preparation for winter
WARNING
■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of
vehicle control and cause death or seri-
ous injury.
●Use tires of the specified size.
●Maintain the recommended level of air
pressure.
●Do not drive in excess of 75 mph (120
km/h), regardless of the type of snow
tires being used.
●Use snow tires on all, not just some
wheels.
■When installing tire chains
Before installing tire chains, make sure to
disable all functions of the vehicle height
control of the electronically modulated
air suspension. Otherwise, the vehicle
height may change while installing the
tire chains and part or your body may be
caught under the vehicle, possibly caus-
ing injury. ( P.303)
■Driving with tire chains
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in the vehicle
being unable to be driven safely, and may
cause death or serious injury.
●Do not drive in excess of the speed
limit specified for the tire chains being
used, or 30 mph (50 km/h), which-
ever is lower.
●Avoid driving on bumpy road surfaces
or over potholes.
●Avoid sudden acceleration, abrupt
steering, sudden br aking and shifting
operations that cause sudden engine
braking.
●Slow down sufficiently before entering
a curve to ensure that vehicle control is
maintained.
●Do not use LTA (Lane Tracing Assist)
system.
