: Maintenance Main Items
Replace engine oil
Replace engine oil and oil filter
Inspect front and rear brakes
Check parking brake adjustment
Inspect these items: Tie rod ends, steering gear box, and boots
Suspension components
Driveshaft boots
Brake hoses and lines (including ABS)
All fluid levels and condition of fluids
Exhaust system
Fuel lines and connections Maintenance Sub Items
Rotate tires
Replace air cleaner element If you drive in dusty conditions, replace
every 15,000 miles (24,000 km).
Replace dust and pollen filter If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and
from diesel-powered vehicles, replace every 15,000
miles (24,000 km).
Inspect drive belt
Replace transmission and transfer fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher
transmission and transfer temperatures. This
requires transmission and transfer fluid changes
more frequently than recommended by the
maintenance minder. If you regularly drive your
vehicle under these conditions, have the transmission
and transfer fluid changed at 60,000 miles
(100,000 km), then every 30,000 miles (48,000 km).
Replace spark plugs
Inspect valve clearance
Replace engine coolant
Replace rear differential fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid. This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles
(12,000 km), then every 15,000 miles (24,000 km).

Reinstall the engine oil f ill cap, and
tighten it securely. Wait a f ew
minutes, and recheck the oil level on
the engine oil dipstick. Do not f ill
above the upper mark; you could
damage the engine.Oil is a major contributor to your
engine’s perf ormance and longevity.
Your vehicle is equipped with a high-
perf ormance turbocharged engine
that requires the use of synthetic
motor oil. Always use Mobil 1
5W-30 or an equivalent oil that meets
the Acura HTO-06 standard. Not all
synthetic oils will meet this standard.
Only use oils that display the
HTO-06 standard on the label.
Failure to use Mobil 1
or an
equivalent oil that meets the HTO-06
standard can lead to a reduction in
engine perf ormance or durability,
and can cause engine damage not
covered by your warranty.
Unscrew and remove the engine oil
fill cap on top of the valve cover.
Pour in the oil slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment. Required Engine Oil
