2008 HONDA RIDGELINE oil change

Your vehicle’s exhaust contains
carbon monoxide gas. Carbon
monoxide should not enter the
vehicle in normal driving if you
maintain your vehicle properly and
f ollow the inf ormation on this page.High levels of carbon monoxide can
collect rapidly in enclosed areas,
such as a garage. Do not run the
engine with the garage door closed.
Even with the door open, run the
engine only long enough to move the
vehicle out of the garage.
Have the exhaust system inspected
f or leaks whenever:
The vehicle is raised f or an oil
change.
You notice a change in the sound
of the exhaust.
The vehicle was in an accident
that may have damaged the
underside. With a truck cap installed and the
back window open, engine exhaust
may enter the vehicle and cause a
hazardous condition. Keep the back
window tightly closed whenever you
drive with a truck cap installed.
If you must sit in your parked vehicle
with the engine running, even in an
unconf ined area, adjust the heating
and cooling system/climate control
system as f ollows:
Select the f resh air mode.
Select the mode.
Turn the f an on high speed.
Set the temperature control to a
comfortable setting.

Help assure your vehicle’s f uture
reliability and perf ormance by paying
extra attention to how you drive
during the f irst 600 miles (1,000 km).
During this period:Avoid full-throttle starts and rapid
acceleration.
Do not change the oil until the
scheduled maintenance time.
Avoidhardbrakingforthefirst
200 miles (300 km).
Do not tow a trailer.
You should also f ollow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced. Your vehicle is designed to operate
on unleaded gasoline with a pump
octane number of 87 or higher. Use
of a lower octane gasoline can cause
a persistent, heavy metallic rapping
noise that can lead to engine damage.
We recommended using a quality
gasoline containing detergent
additives that help prevent fuel
system and engine deposits.
In addition, in order to maintain good
perf ormance, f uel economy, and
emissions control, we strongly
recommend, in areas where it is
available, the use of gasoline that
does NOT contain manganese-based
f uel additives such as MMT.
Use of gasoline with these additives
may adversely af f ect perf ormance,
and cause the malfunction indicator
lamp on your instrument panel to
come on. If this happens, contactyour authorized dealer f or service.
Some gasoline today is blended with
oxygenates such as ethanol or
MTBE. Your vehicle is designed to
operate on oxygenated gasoline
containing up to 10 % ethanol by
volume and up to 15 % MTBE by
volume. Do not use gasoline
containing methanol.
If you notice any undesirable
operating symptoms, try another
service station or switch to another
brand of gasoline.
Premium f uel is recommended when
towing in certain conditions (see
page ).

If the message ‘‘SERVICE dUE NOW’’ does not appear more than 12 months
after the display is reset, change the engine oil every year.
See information on maintenance and emissions warranty on page .Independent of the maintenance messages 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.
NOTE: 1:

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).
Driving in mountainous terrain at very low vehicle speeds,
towing a trailer, or driving when fully loaded 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 every 30,000 miles
(48,000 km).
If you drive regularly in very high temperatures (over 110°F,
43°C), in very low temperatures (under-20°F, -29°C), or towing a
trailer, replace every 60,000 mile (U.S.)/100,000 km (Canada)
Driving in mountainous terrain at very low vehicle speeds,
towing a trailer, or driving when fully loaded causes more
mechanical (shear) stress and fluid deterioration. 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).

drain bolt and washer f rom the
bottom of the engine. Drain the oil
into an appropriate container.
Your vehicle does not require any oil
additives. Additives may adversely
af f ect the engine or transmission
perf ormance and durability.
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 shown on the information
display.
Run the engine until it reaches
normal operating temperature,
then shut it off.
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.
Always change the oil and f ilter
according to the maintenance
messages shown on the odometer
