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

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.

■Washing the vehicle
To prevent paint deterioration and corrosion on the body and components (wheels
etc.), wash the vehicle immediately if it becomes dirty. Hand washing is recommended
to preserve the paint finish.
1 Working from top to bottom, liberally apply water to the vehicle body, wheel wells
and underside of the vehicle to remove any dirt and dust.
2 Wash the vehicle body using a sponge or soft cloth, such as a chamois.
3 For hard-to-remove marks, use a neutral detergent and rinse thoroughly with
water.
