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.

2-4. Using other driving systems

When driving
■Start-off acceleration
Start-off acceleration depends on how much the accelerator pedal is depressed.
■Usage restrictions
●Launch control cannot be set if the total mileage shown on the odometer is less
than 310 miles (500 km).
●Launch control cannot be set until the engine and transmission are fully warmed
up. Before using launch control, warm up the vehicle by driving it.
●Launch control cannot be set if there is a malfunction in the engine, transmis-
sion, drive control system or other relevant systems.
●As launch control places a significant load on the vehicle's mechanisms, it can-
not be used two or more times in succes sion. After using launch control, cruise
at a normal speed for approximately 10 minutes to allow vehicle mechanisms to
cool down.
●To protect the systems, the number of times that launch control can be used is
limited. To check how many times launch control has been used on your vehicle,
contact your Lexus dealer.
CAUTION
■Launch control precautions
●Do not use on public roads.
●Use only when road and ambient conditions are safe.
●Before use, ensure that no people or obstructions are nearby.
●Proper use of launch control requires a professional level of driving skill. When
driving, always check track conditions and the surrounding area.
NOTICE
■To prevent system damage
●Always follow the correct operation procedures as described in this manual.
●Only use launch control on dry, paved ro ad surfaces, as slippery or loose road
surfaces may cause damage to the vehicle's mechanisms.
