Maintenance Acura RL 2006 Owner's Guide

Your vehicle does not require any oil
additives. Additives may adversely
af f ect the engine or transmission
perf ormance and durability.Open the hood, and remove the
engine oil f ill cap. Remove the oil
drain bolt and washer f rom the
bottom of the engine. Drain the oil
into an appropriate container.
You may use a synthetic motor oil if
it meets the same requirements
given f or a conventional motor oil: it
displays the API Certif ication Seal,
and it is the proper weight. You must
f ollow the oil and f ilter change
intervals given on the maintenance
schedule.
Always change the oil and f ilter
according to the maintenance
messages shown on the multi-
inf ormation display. The oil and f ilter
collect contaminants that can
damage your engine if they are not
removed regularly.
Changing the oil and f ilter requires
special tools and access f rom
underneath the vehicle. The vehicle
should be raised on a service station-
type hydraulic lif t f or this service.
Unless you have the knowledge and
proper equipment, you should have
this maintenance done by a skilled
mechanic.
Run the engine until it reaches
normal operating temperature,
then shut it off.

Check the brake f luid level in the
reservoirs monthly.
Replace the brake f luid every 3 years,
independent of mileage.
If the level is below the lower
mark, add f luid into the dipstick
tube to bring it to the upper mark.
Pour the f luid slowly and caref ully
so you do not spill any. Clean up
any spill immediately; it could
damage components in the engine
compartment. Insert the dipstick all the way back
into the transmission securely as
shown in the illustration.
The transmission should be drained
and ref illed with new f luid when this
service is shown on a maintenance
message in the multi-inf ormation
display.
If you are not sure how to add f luid,
contact your dealer.
Always use Honda ATF-Z1
(automatic transmission f luid). If
it’s not available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can affect the shift quality.
Have the transmission f lushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient. Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage. Using any non-Honda brake f luid can
cause corrosion and decrease the lif e
of the system. Have the brake
system f lushed and ref illed with
Honda Heavy Duty Brake Fluid
DOT 3 as soon as possible.

Dirt build-up in the loops of the seat
belt anchors can cause the belts to
retract slowly. Wipe the insides of
the loops with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.
If your seat belts get dirty, use a sof t
brush with a mixture of mild soap
and warm water to clean them. Do
not use bleach, dye, or cleaning
solvents. Let the belts air-dry bef ore

To saf ely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inf lated.Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort.
Underinf lated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,are
more prone to damage f rom road
hazards, and wear unevenly.
The f ollowing pages give more
detailed inf ormation on how to take
care of your tires and what to do
when they need to be replaced.
Check the pressure in the tires when
they are cold. This means the vehicle
has been parked f or at least three
hours, or driven less than 1 mile (1.6
km). Use a gauge to measure the air
pressure in each tire at least once a
month. Even tires that are in good
condition may lose one to two psi (10
to 20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime. We recommend that you visually
check your tires every day. If you
think a tire might be low, check it
immediately with a tire gauge.
Thetirepressuremonitoringsystem
(TPMS)willwarnyouwhenatire
pressure is low. See page f or
inf ormation on the TPMS. Add or release air, if needed, to
match the recommended cold tire
pressures on page .384

Inf lation Guidelines
Maint enance
383
Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this
owner’s manual regarding tire
inflation and maintenance.

In addition to proper inf lation,
correct wheel alignment helps to
decrease tire wear. If you f ind a tire
is worn unevenly, have your dealer
check the wheel alignment.
Have your dealer check the tires if
you f eel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed f rom the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comf ort and tire lif e. For best results,
have the installer perform a dynamic
balance.To help increase tire lif e and
distribute wear more evenly, rotate
the tires every 7,500 miles (12,000
km). Move the tires to the positions
showninthecharteachtimethey
are rotated. If you purchase
directional tires, rotate only f ront-to-
back.
Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a
band 1/2 inch (12.7 mm) wide across
the tread. This shows there is less
than 1/16 inch (1.6 mm) of tread lef t
on the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators.
When the tires are rotated, make
sure the air pressures are checked.

Check the condition of the battery
monthlybylookingatthetest
indicator window. The label on the
battery explains the test indicator’s
colors. Battery posts,
terminals, and related accessories
contain lead and lead compounds. Check the terminals f or corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it of f with plain
water. Dry off the battery with a
cloth or paper towel. Coat the
terminals with grease to help prevent
f uture corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualif ied technician. If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s
electrical system. Always disconnect
the negative ( ) cable first, and
reconnect it last.
To see the label, remove the battery
cover (see page ). 391 WARNING:
Wash your hands af ter handling.

The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt you.
Wear protective clothing and a
face shield, or have a skilled
mechanic do the battery
maintenance.

If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully.
If the ABS indicator and the VSA

The burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx), and hydrocarbons (HC).
Gasoline evaporating f rom the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to f orm photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas.
In Canada, Acura vehicles comply
with the Canadian emission
requirements, as specif ied in an
agreement with Environment
Canada, at the time they are
manuf actured.
Your vehicle has a positive
crankcase ventilation system. This
keeps gasses that build up in the
engine’s crankcase f rom going into
the atmosphere. The positive crankcase ventilation valve routes
them from the crankcase back to the
intake manif old. They are then
drawn into the engine and burned.
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The onboard ref ueling vapor
recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .
The United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
