■Oil level
An oil level sensor is installed in the oil tank to measure the amount of oil present. The
reading from this sensor is displayed to the driver. This allows the engine oil level to
be checked simply by operating the control pad, without needing to get out of the
vehicle.

Checking and topping up the oil level
The LFA uses a dry-sump oil system to circulate the engine oil between the
engine and the oil tank. Therefore, depending on the conditions, the level of oil
in the oil tank can vary greatly.
Cautions when checking the oil level
• In order to attain the most accurate
m e a s u r e m e n t , l e a v e t h e e n g i n e
running after driving and check the
oil level while the engine is idling. The
oil level will take time to stabilize if the
engine is stopped and started again.
• As the engine oil level in the oil tank
va r i e s d e p e n d i n g o n t h e d r i v i n g
condition of the vehicle immediately
before measurement, the results may
vary even if the overall oil amount is
constant.
MAX
MIN
Cautions when topping up the oil level
• Ensure that the oil level does not fall below the MIN marking.
• The space between the MAX and MIN markings represents approximately
2.1 qt. (2.0 L, 1.8 Imp. qt.). While the oil may be topped up as required, never
add more than 0.5 qt. (0.5 L, 0.4 lmp. qt.) at one time.
• Even if the oil level is below the MAX mark, do not add more oil than
necessary.
Oil level gauge
• The oil level gauge installed on the oil tank is for oil changes. Do not use it to
check the current oil level.

■Over rev warning
When the engine speed enters the red
zone, a red ring will appear within the
tachometer display area to warn the
driver even if they are focused solely on
the road.
■
■Rev Indicator (Except in auto mode)
When the engine reaches a set speed, a green or amber ring will appear within the
tachometer. The selectable engine speed range is between 4,000 and 9,000 rpm.
(Green or amber indicators can be selected to show according to set engine speeds.)
This visual indication allows the driver to quickly grasp the engine speed without
having to read the tachometer needle and time their upshifts accordingly even when
they are focused solely on the road.

■
■Rev Peak
An afterimage of the tachometer needle at the highest engine speed attained prior
to an upshift or deceleration will be retained for approximately 0.5 seconds. This
function simulates the “telltale needle” used in traditional analog racing tachometers to
help the driver time their upshifts and check over-revs on downshifting etc.
The Rev Peak function can be turned on or off from “Settings” on the menu display.
The color of the tachometer needle afterimage will change in accordance with that of
the actual tachometer needle.

Maintaining the vehicle’s exterior
When washing the vehicle, be careful not to
touch the hood grilles, bezels in the radiator
grilles, or exhaust pipes and surrounding
area until they have cooled sufficiently, as
these components may cause burns.

• Do not apply water to the inside of the engine compartment. Doing so may cause the
electrical components etc. to catch fire.
• Do not flush water over or into the hood grilles (especially the arrowed portion in the
illustration).
• Do not flush water over or into the exhaust pipes and surrounding area or the bezels in
the radiator grilles until they have cooled sufficiently.
When using a high-pressure washer
• Do not aim the head of the nozzle at the hood grilles or radiator grilles. Doing so may
negatively affect the engine or cause a malfunction in the electric cooling fan motors that
may result in overheating.
• Do not allow the nozzles of the car wash to come within close proximity of the windows
or rear hatch.
Do not use automatic car washes as they may scratch the vehicle body and damage
the paint.

Advice for long-term storage
■
■Battery
Removing the specified fuse helps to suppress parasitic current.
However, as the battery naturally loses its charge over time, it may become discharged
if the vehicle is stored for more than several months.
If the vehicle battery is discharged ( "
P. 94)
■
■Remove the fuse
1 Turn the ignition switch to the “LOCK” position.
2 Open the hood.
Hood ("P. 12)
3 Open the fuse box lid in the engine
compartment.
Push the tabs in and lift the lid off.
4 While referring to the back of the fuse
box lid for the location, use the pull-
out tool A to remove the “D/C CUT”
fuse B and put it into C.
Make sure that the fuse is firmly inserted.

If the battery is fully discharged or has insufficient charge, perform the following
procedures to gain vehicle access, release the parking brake and use another live
battery to start the engine:
■
■Unlocking the doors
The doors can be unlocked using the
master or valet keys.
