See information on maintenance and emissions warranty on page.
Independent of the maintenance items in the information display, replace
the brake fluid every 3 years.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2, or 3 only if they are noisy.

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 any. Clean up any
spills immediately. Spilled oil could
damage components in the engine
compartment. Required Engine Oil

If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks. Always use Honda Long-lif e Anti-
f reeze/Coolant Type 2. This coolant
is pre-mixed with 50 percent
antif reeze and 50 percent water.
Never add straight antifreeze or
plain water.

The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components.Pour coolant into the reserve tank.
Fill it half way between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Make sure the engine and radiator
are cool.
Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
