Oil is a major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements. It is
highly recommended that you use
Honda Motor Oil in your vehicle f or
optimum engine protection.
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.
Unscrew and remove the engine oil
fill cap on the valve cover. Pour 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. Recommended Engine Oil

µYour vehicle does not require any oil
additives. Additives may adversely
af f ect the engine or transmission
perf ormance and durability.
An oil with a viscosity of 5W-30 is
pref erred f or improved f uel economy
and year-round protection in your
vehicle. You may use a 10W-30 oil if
the temperature in your area never
goes below 20°F ( 7°C).
Make sure the API Certif ication Seal
says ‘‘For Gasoline Engines.’’
The oil viscosity or weight is
provided on the container’s label.

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.
Always change the oil and f ilter
according to the maintenance
messages shown on the 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.

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 according to the
maintenance messages displayed on
the information display. Move the
tires to the positions shown in the
chart each time they are rotated. If
you purchase directional tires, rotate
only f ront-to-back.
When the tires are rotated, make
sure the air pressures are checked.The tires that came on your vehicle
were designed and constructed to
provide superior grip during
acceleration, braking, and cornering.
As a trade-of f , they will wear more
rapidly than tires used on ordinary
passenger vehicles. Because of the
vehicle’s weight distribution, and the
fact that the front wheels are the
driving wheels, you can expect them
to wear more rapidly than the rear
tires.On Si model only

If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle’s

the negative ( ) cable first, and
reconnect it last.
If additional battery maintenance is
needed, see your dealer or a
qualif ied technician.
Battery posts,
terminals, and related accessories
contain lead and lead compounds. If your vehicle’s battery is
disconnected, or goes dead, the
audio system will disable itself . The

If the indicator comes on repeatedly,
even though it may turn of f as you
continue driving, have your vehicle
checked by the dealer as soon as
possible.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If this indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage. If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It can take several
days of driving under various
conditions to set the codes again.
If you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. You will also see a
‘‘CHECK FUEL CAP’’ message on
the inf ormation display. Tighten the
cap until it clicks at least once.
Tightening the cap will not turn the
indicator of f immediately; it can take
several days of normal driving. To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle f or an emissions
test until the readiness codes are set.

Your vehicle has also been equipped
with a TPMS malf unction indicator
to indicate when the system is not
operating properly. The TPMS
malf unction indicator is provided by
a separate telltale, which displays the
symbol ‘‘TPMS’’ when illuminated.
When the malf unction indicator is
illuminated,
the system may not be able to detect
or signal low tire pressure as
intended.
TPMS malf unctions may occur f or a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS f rom
f unctioning properly.Always check the TPMS malf unction
telltale af ter replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to f unction
properly.
