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.

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
■If the engine does not start
●Repeat the procedure again. If the engine does not start after a few tries, the
“ENGINE START” switch may be malfunctioning. Have the vehicle inspected
by your Lexus dealer.
●Check to make sure that the brake pedal is firmly depressed and that “N” is dis-
played in the gear indicator. (If the brake pedal is not depressed or “N” is not
displayed, the engine will not start.)
●The engine immobilizer system may not have been deactivated. ( P. 5 3 )
●In order to protect the engine, the engine may not start when the engine coolant
temperature or the engine oil temperature is below -13 F (-25C). In that case,
a buzzer will sound and “Temp low Engine cannot be started” will be shown on
the meter. ( P. 3 2 7 )
■When the steering lock cannot be released
■Key reminder function
A buzzer sounds if the driver’s door is opened while the ignition switch is in the
“LOCK” or “ACC” position to remind you to remove the key.
■After reconnecting the battery
If the gear indicator is not displayed when an attempt is made to start the engine,
the engine is not yet ready to start. Depr ess the brake pedal for several seconds and
wait for the gear indicator to appear.
When starting the engine, the ignition switch
may seem stuck in the “LOCK” position. To
free it, turn the key while turning the steering
wheel slightly left and right.

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.
