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.

Trip informationThe information on the trip infor-
mation display can be changed
when in the normal display by
pressing up or down on the control
pad.
■ Trip meter
■ Current fuel consumption
■ Average fuel consumption
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 indepen-
dently.
The function can be reset by pressing up or
down on the control pad for longer than
one second when the trip meter “A” or “B” is
displayed.
Displays the current rate of fuel consump-
tion.
Displays the average fuel consumption
since the function was reset.
The function can be reset by pressing up or
down on the control pad for longer than
one second when the average fuel con-
sumption is displayed.

■Average vehicle speed
■ Driving range
Displays the average vehicle speed since
the engine was started or the function was
reset.
The function can be reset by pressing up or
down on the control pad for longer than
one second when the average vehicle
speed is displayed.
Displays the estimated maximum distance
that can be driven with the quantity of fuel
remaining.
This distance is computed based on your
average fuel consumption. As a result, the
actual distance that can be driven may dif-
fer from that displayed.
When only a small amou nt of fuel is added
to the tank, the display may not be updated.
■Va r i a b l e r e d z o n e
■Engine coolant and engine oil temperature displays
In congested traffic, the engine coolant and engine oil displays may show a higher
than usual temperature. This is not a ma lfunction. If temperatures are abnormal,
these displays will flash.
To help protect the engine, the red zone of
the tachometer starts at different engine
speeds ranging from 4400 rpm to 9000
rpm depending on the engine coolant tem-
perature.
