Before driving
■When the power window does not close normally
If the jam protection function is operating abnormally and a window cannot be
closed, perform the following operations using the power window switch on the rel-
evant door.
●After stopping the vehicle, the window can be closed with the door closed by
holding the power window switch in the one-touch closing position while the
ignition switch is turned to the “ON” position.
●If the window still cannot be closed even by carrying out the operation
explained above, initialize the function by performing the following procedure.
Hold the power window switch in the one-touch closing position. Con-
tinue holding the switch for a further 6 seconds after the window has
closed.
Hold the power window switch in the one-touch opening position. Con-
tinue holding the switch for a further 2 seconds after the window has
opened completely.
Hold the power window switch in the one-touch closing position once
again. Continue holding the switch for a further 2 seconds after the win-
dow has closed.
If you release the switch while the window is moving, start again from the beginning.
If the window continues to close but then re-open slightly even after performing the
above procedure correctly, have the vehicle inspected by your Lexus dealer.
■Customization that can be conf igured at your Lexus dealer
Settings of the linked key and wireless remote control operation can be changed.

1-6.Theft deterrent system
Engine immobilizer system
The vehicle's keys have built-in transponder chips that prevent the engine
from starting if the key has not been previously registered in the vehicle's on-
board computer.
Never leave the keys inside the vehicle when you leave the vehicle.
■ Setting and canceling the engine immobilizer system
U.S.A.
The system will set after the key has been removed from the ignition
switch.
The system will be canceled when the registered key is inserted into the
ignition switch.
Canada
The indicator light flashes after the
key has been removed from the
ignition switch to indicate that the
system is operating.
The indicator light stops flashing
after the registered key has been
inserted into the ignition switch to
indicate that the system has been
canceled.
■System maintenance
The vehicle has a maintenance-free type engine immobilizer system.
■Conditions that may cause the system to malfunction
●If the grip portion of the key is in contact with a metallic object
●If the key is in close proximity to or touching a key to the security system (key
with a built-in transponder chip) of another vehicle

2-1. Driving procedures

When driving
Starting on a steep uphillThe hill-start assist control ( P. 166) operates to help reduce the dis-
tance that the vehicle rolls backward when starting on an incline. How-
ever, under certain conditions hill-start assist control may not work. In that
case, follow the procedure below.
Make sure that the parking brake is set and select 1st gear.
Gently depress the accelerator pedal.
Release the parking brake.
■Shifting gears
P. 1 0 2
■Breaking in your new LFA
To extend the life of the vehicle, observing the following precautions is recom-
mended:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.

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
CAUTION
■When the vehicle is stopped
●Do not race the engine.
• If the vehicle is in any gear other than Neutral the vehicle may accelerate sud-denly and unexpectedly, causing an accident.
• Running the engine at high speed while the vehicle is stopped may cause the exhaust system to overheat, which could result in a fire if flammable material is
nearby.
• Racing the engine may emit loud noise, and possibly cause a nuisance, espe- cially after just starting the engine. This is because the structure of the exhaust
pipes cause the sound emitted from the exhaust to be louder than usual for
approximately 1 minute after the engine is started.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do no t enter the vehicle interior.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of
the vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such
as the glove box or on the floor, it may be lit accidentally when luggage is loaded
or the seat is adjusted, causing a fire.
●Do not attach adhesive discs to the wind shield or windows. Do not place contain-
ers such as air fresheners on the instru ment panel or dashboard. Adhesive discs
or containers may act as lenses, causing a fire in the vehicle.

CAUTION
■When starting the engine
Always start the engine while sitting in the driver’s seat. Do not press the accelera-
tor pedal while starting the engine under any circumstances.
Doing so may cause an accident, resulting in death or serious injury.
■Caution when driving
Do not turn the ignition switch to the “LOCK” position while driving. An accident
may result if the engine is stopped while driving.
If you must turn the engine off while the vehicle is moving (due to an emergency),
turn the ignition switch on ly to the “ACC” position. (P. 355)
NOTICE
■To prevent battery discharge
Do not leave the ignition switch in the “A CC” or “ON” position for long periods of
time without the engine running.
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.
