driving, the pointer may rise to theupper end of the white section of the
gauge. If it reaches the red (hot)
mark, pull saf ely to the side of the
road. For more information, see page

U.S. Vehicles:
According to state and federal
regulations, f ailure to perf orm
maintenance on the items marked
with will not void your emissions
warranties. However, Acura
recommends that all maintenance
services be perf ormed in accordance
with the intervals indicated by the
multi-inf ormation display.
Youshouldcheckthefollowing
items at the specif ied intervals. If
you are unsure of how to perf orm
any check, turn to the appropriate
page listed.
We recommend using Acura parts
and fluids whenever you have
maintenance done. These are
manuf actured to the same high
quality standards as the original
components, so you can be conf ident
of their perf ormance and durability.
Your authorized dealer knows your
vehicle best and can provide
competent, ef f icient service.
However, service at a dealer is not
mandatory to keep your warranties
in effect. Maintenance may be done
by any qualif ied service f acility or
person who is skilled in this type of
automotive service. Keep all receipts
as proof of completion, and have the
person who does the work f ill out
your Maintenance Journal or
Canadian Maintenance Log. Check

Maintenance Sub Items
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).
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
Replace timing belt and inspect water pump If you drive regularly in very high temperatures (over
110°F, 43°C), or in very low temperatures (under20°F, 29°C), replace every 60,000 mile (U.S.)/
100,000 km (Canada).
Inspect valve clearance

ENGINE COOLANT
RESERVOIR
2009 RL

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.If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
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.
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 distilled
water. Never add straight antif reeze
or plain water.

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
2009 RL

The coolant level should be up to
the base of the f iller neck. Add
coolant if it is low.
When the radiator and engine are
cool, relieve any pressure in the
cooling system by turning the
radiator cap counterclockwise,
without pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise.
Lift up the lid on the front
bulkhead cover f rom the f ront.

Clean up any spill immediately; it
could damage components in the
engine compartment.
