2-1. Driving procedures
■Engine speed restrictions
The following restrictions exist for engine protection:
●The engine speed is limited to 7400 rpm if the total mileage shown on the
odometer is less than 310 miles (500 km).
●The engine speed is limited when the engine is not sufficiently warmed-up, such
as immediately after the engine is started or during the engine warm-up period.
The variable red zone shows the maximum engine speed currently available.
(  P. 1 1 9 )
●The engine speed is limited to 4400 rpm for approximately 8 minutes when the
engine is started with the coolant temperature at 5 F (-15 C) or lower.
●The engine speed may be limited when either the coolant temperature gauge
or oil temperature gauge is flashing.
■Idling with five cylinders
To improve fuel consumption, the engine may idle at a reduced speed using five cyl-
inders on one side of the engine whil e stopped or immediately before stopping
when 1st gear is selected in AUTO driving mode. During this time, “5 cylinders
idling” will be displayed on the meter an d vibration or a change in engine sound
may occur. This is normal and does not indicate a malfunction.
■ASG (Automated Sequential Gearbox) operating sounds
 P. 1 1 0
■Braking sound
●As the LFA uses CCM (Carbon Ceramic Material) brake discs with high-fric-
tion pads, it may be possible to hear the sound of the brakes operating (such as
a rubbing or squealing sound). This is normal and does not indicate a malfunc-
tion.
●The sound of a motor operating may be heard after the engine is stopped. This
does not indicate a malfunction.
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from driving at high speeds on wet surfaces such as on an expressway in
the rain, as the LFA is fitted with wide-t read tires that may increase the risk of
hydroplaning.

When driving
NOTICE
■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 vehicle:
●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 following:
●Brake function
●Changes in quantity and quality of oil an d fluid used for the engine, transmission,
differential, etc.
●Lubrication problems of bearings, joints, etc.

2-1. Driving procedures
■Shift speed
●When the driving mode is changed, the shift speed levels will be set as follows:
●Shift shock increases as the shift speed becomes faster.
■When parking the vehicle
There is no P (Park) setting for the ASG. When parking the vehicle, set the parking
brake, select 1st gear or Reverse, and ch eck that the gear indicator shows “D1”, “1”
or “R” before stopping the engine.
●Approximately one second after the engine is stopped, the vehicle will enter a
parked gear state.
If the vehicle fails to enter a parked gear state, a buzzer sounds and the gear
indicator flashes. Select Neutral and then follow the same procedure again.
●Make sure to stop the engine. Opening the driver’s door without first stopping
the engine will cause a warning to sound and Neutral to be automatically
selected after 5 seconds. Even if the driver’s door is not opened, a warning will
sound and Neutral will be automatically selected after 90 seconds.
■ASG operating sounds
●Even when the engine is stopped, operating sounds of the electric oil pump may
be heard. This is normal and does not indicate a malfunction.
●As the drive train of the LFA is designed to be especially responsive to acceler-
ator pedal operation, a sound may be heard from the transaxle when driving at
low engine speeds. This does not indicate a malfunction.
■Customization that can be configured at your Lexus dealer
The sound pattern of the reverse warning buzzer can be changed.

■Outside temperature display
●The temperature display shows temperatures within the range of -40F (-40C)
and 122 F (50C).
●In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change:
• When the vehicle is stopped, or moving at low speeds (less than 15 mph [25
km/h])
• When the outside temperature has chan ged suddenly (at the entrance/exit of
a garage, tunnel, etc.)
●When “--” or “E” is displayed, the system may be malfunctioning. Take your vehi-
cle to your Lexus dealer.
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone.

vehicle in a safe place.
• The display on the engine coolant temperature gauge flashes. (
P. 3 5 1 )
• The display on the engine oil temperature gauge flashes. (
P. 313)
●In the following situations, the engine may be malfunctioning. Immediately stop
the vehicle in a safe place and contact your Lexus dealer.
• The oil pressure gauge display does not show an increase even if the acceler-
ator pedal is depressed.
• The “Engine oil pressure low” warning message is displayed.

■Meter operation restrictions while vehicle is in motion
While the vehicle is in motion, some menu items cannot be changed using the con-
trol pad. Restricted items are displayed in gray or without an arrow. These items can
be operated once the vehicle is stopped.
■“Rev Ind” (rev indicator)
●Even if the green or amber indicator is set to 9000 rpm, the over-rev warning
will be displayed.
●If the green and amber indicators are both set to the same engine speed, the
indicator will be shown in amber.
■Measuring the engine oil level
●The dry sump lubrication system circulates the engine oil between the engine
and oil tank according to driving conditions. Accordingly, the engine oil level in
the oil tank may vary even if the overall amount is constant, affecting the mea-
surement results.
●It takes some time for the engine oil level to stabilize after the engine is started.
To obtain a more stable result, drive the vehicle for a while and then perform the
measurement without stopping the engine.
●If an attempt to measure the oil level is made immediately after the previous oil
level measurement process was completed, the previous measurement may be
displayed.
●If the measurement result flashes, the measuring function is malfunctioning.
Have the vehicle inspected by your Lexus dealer.
■Engine oil maintenance
“Oil maintenance required” will be displayed once the vehicle has been driven for
more than 6214 miles (10000 km) since the last reset. (
P. 3 2 7 )
The engine oil may need to be replaced earlier depending on driving conditions.
●Over-rev warning (regular setting)
If the engine speed enters the red zone, the
over-rev warning will be shown in red
regardless of the set speed.

Maintenance and care
NOTICE
■Application of coatings to the vehicle body
Do not apply any kind of coating to the vehicle body as doing so may damage the
paint or reduce its durability.
■To prevent paint deterioration and corrosion on the body and components (alu-
minum wheels etc.)
Observe the following precautions:
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the paint
surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corroding, remove any dirt and store in a place with
low humidity when storing the wheels.
For the Matte Black, pay attent ion to the following as well:
●If anything is spilled on a painted surface, wipe it off as soon as possible.
If spilled washer fluid or alkaline fluids are left as is, the paint in the affected area
may deteriorate, causing blemishing.
●Do not wax or apply coating to the vehicle.
Doing so may cause a change in the body surface's texture or irregularities in the
paint.

4-3. Do-it-yourself maintenance
Add oil based on the oil level shown on the meter.
Do not add more than 0.5 qt. (0.5 L, 0.4 Imp. qt.) at a time regardless of
the oil level reading.
To check the oil level again, install the oil filler cap by turning it
clockwise.
Check the oil level using the “Oil Level” display and repeat the
above procedure if more oil is required.
Even if the measurement result shows that the oil is below the maximum
level, be careful not to add more oil than necessary.
Install the oil filler cap by turning it clockwise.
■Engine oil consumption
●The amount of engine oil consumed depe nds on the oil viscosity, the quality of
the oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds and fre-
quent acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumpt ion, keep in mind that the oil may
have become diluted, making it difficult to judge the true level accurately.
●Oil consumption: Max. 1.1 qt./600 miles (0.9 Imp. qt./600 miles, 1.0 L/1000
km)
●If your vehicle consumes more than 1.1 qt. (1.0 L, 0.9 Imp. qt.) every 600 miles
(1000 km), contact your Lexus dealer.
■After the engine oil has been changed
The “Oil Maintenance” display on the mete r needs resetting. Have the display reset
at your Lexus dealer. ( P. 1 3 2 )
