Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precautions:
■When working on the engine compartment
●Keep hands, clothing, and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, exhaust manifold, etc. right after driving as
they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flam-
mable.
■When working near the electric cooling fan
Be sure the ignition switch is in the “LOCK” position.
With the ignition on, the electric cooling fan may automatically start to run if the air
conditioning is on. ( P. 2 6 1 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in the eyes.
NOTICE
■If you remove the air cleaner filters
Driving with the air cleaner filters remo ved may cause excessive engine wear due
to dirt in the air. Also a backfire could cause a fire in the engine compartment.

Maintenance and care
Air conditioning filter
The air conditioning filter must be changed regularly to maintain air condi-
tioning efficiency.
Set the air conditioning system to recirculated air mode.
(P. 190, 197)
The air conditioning filter case cannot be removed with the system in
the outside air mode.
Turn the ignition switch to the “LOCK” position.
Open the glove box. ( P. 210)
Remove the filter cover.
Remove the filter case.
Remove the air conditioning filter
from the filter case and replace it
with a new one.
The “UP” marks shown on the fil-
ter and the filter case should be
pointing up.

4-3. Do-it-yourself maintenance
■Checking interval
Inspect and replace the air conditioning filter according to the maintenance sched-
ule. In dusty areas or areas with heavy traffic flow, early replacement may be
required. (For scheduled maintenance information, please refer to the “Owner's
Manual Supplement” or “Scheduled Maintenance”.)
■If air flow from the vents decreases dramatically
The filter may be clogged. Check the filter and replace if necessary.
NOTICE
■When using the air conditioning system
Make sure that a filter is always installed.
Using the air conditioning system without a filter may cause damage to the system.

Vehicle specifications
Lubrication system■ Specified engine oil for the LFA
*1: The oil filters used are exclusive to the LFA. When the oil is changed, the oil fil-
ters should also be replaced.
*
2: The lifetime of the vehicle depends greatly on the quality of oil used. The use of “Mobil 1 5W-50” is most suitable for your vehicle and is recommended.
Oil capacity*1
(Amount of oil required
for an oil change 
reference) With twin air-cooled oil cooler
18.0 qt. (17.0 L, 15.0 Imp. qt.)
With single air-cooled oil cooler
16.9 qt. (16.0 L, 14.1 Imp. qt.)
Oil brand*2“Mobil 1 5W-50”
Recommended API
grade
SM or SN
■Engine oil viscosity
●The 5W portion of the oil viscosity rating
indicates the characteristic of the oil
which allows cold startability. Oils with a lower value before the W allow for eas-
ier starting of the engine in cold weather.
●The 50 in 5W-50 indicates the oil viscosit y when the oil is at its operating tem-
perature. An oil with a higher viscosity may be better suited if the vehicle is
operated at high speeds, or under extreme load conditions.
NOTICE
■To prevent engine damage
If “Mobil 1 5W-50” is not available, another oil of equivalent quality to “Mobil 1
5W-50” may be used. In this case, do not start the engine if the engine coolant or
oil temperature is below 5 F (-15C), and do not drive the vehicle under extreme
load conditions.
