How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where you
change the oil prior to a CHANGE
ENGINE OIL SOON message being
turned on, reset the system.
To reset the Engine Oil Life System:
1. Turn the ignition to ON/RUN,
with the engine off.
2. Press the vehicle information
button until OIL LIFE
REMAINING displays.
3. Press and hold the set/reset
button until 100% is displayed.
You will hear three chimes
and the CHANGE ENGINE OIL
SOON message will go off.
4. Turn the key to LOCK/OFF.If the CHANGE ENGINE OIL SOON
message comes back on when
you start the vehicle, the engine oil
life system has not reset. Repeat
the procedure.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer’s warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your own
oil, be sure to drain all the oil from the
lter before disposal. Never dispose
of oil by putting it in the trash, pouring
it on the ground, into sewers, or into
streams or bodies of water. Recycle
it by taking it to a place that collects
used oil.
Engine Air Cleaner/Filter
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/lter at the
MaintenanceIIintervals and replace
it at the rst oil change after each
50,000 mile (80 000 km) interval.
SeeScheduled Maintenance
on page 6-3for more information.
If you are driving in dusty/dirty
conditions, inspect the lter at each
engine oil change.
SeeEngine Compartment Overview
on page 5-10for the location of
the engine air cleaner/lter.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter,
remove the lter from the vehicle and
lightly shake the lter (away from
vehicle) to release loose dust and
dirt. If the lter remains caked with
dirt, a new lter is required.
5-14 Service and Appearance Care

How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level surface.
If the level is below the bottom of
the ller plug hole, you will need to
add some lubricant. Add enough
lubricant to raise the level to
the bottom of the ller plug hole.
Use care not to overtighten the plug.
What to Use
Refer to the Maintenance Schedule
to determine what kind of lubricant to
use. SeeRecommended Fluids and
Lubricants on page 6-12.Headlamp Aiming
Headlamp aim has been preset at
the factory and should need no
further adjustment.
However, if your vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to
the low-beam headlamps may be
necessary if oncoming drivers ash
their high-beam headlamps at
you (for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
you take the vehicle to your
dealer/retailer for service.
Bulb Replacement
For the proper type of replacement
bulbs, seeReplacement Bulbs
on page 5-35.
For any bulb changing procedure
not listed in this section, contact
your dealer/retailer.
High Intensity Discharge
(HID) Lighting
{CAUTION
The low beam high intensity
discharge lighting system operates
at a very high voltage. If you try
to service any of the system
components, you could be
seriously injured. Have your
dealer/retailer or a qualied
technician service them.
Your vehicle has HID headlamps.
After your vehicle’s HID headlamp
bulb has been replaced, you may
notice that the beam is a slightly
different shade than it was originally.
This is normal. (A) Filler Plug (B) Drain Plug

{CAUTION
Performing maintenance work on
a vehicle can be dangerous. In
trying to do some jobs, you can
be seriously injured. Do your own
maintenance work only if you
have the required know-how and
the proper tools and equipment
for the job. If you have any doubt,
see your dealer/retailer to have a
qualied technician do the work.
SeeDoing Your Own Service
Work on page 5-4.
Some maintenance services can be
complex. So, unless you are
technically qualied and have the
necessary equipment, have
your dealer/retailer do these jobs.
When you go to your dealer/retailer
for service, trained and supported
service technicians will perform
the work using genuine parts.To purchase service information,
seeService Publications Ordering
Information on page 7-13.
Owner Checks and Services on
page 6-8tells what should be
checked, when to check it, and what
can easily be done to help keep
the vehicle in good condition.
The proper replacement parts,
uids, and lubricants to use
are listed inRecommended Fluids
and Lubricants on page 6-12
andMaintenance Replacement
Parts on page 6-14. When the
vehicle is serviced, make sure these
are used. All parts should be
replaced and all necessary repairs
done before you or anyone else
drives the vehicle. We recommend
the use of genuine parts from
your dealer/retailer.
Scheduled Maintenance
When the CHANGE ENGINE
OIL SOON message displays,
service is required for the vehicle.
Have the vehicle serviced as
soon as possible within the next
600 miles (1 000 km). It is possible
that, if driving under the best
conditions, the engine oil life system
might not indicate that vehicle
service is necessary for over a year.
However, the engine oil and lter
must be changed at least once
a year and at this time the system
must be reset. Your dealer/retailer
has trained service technicians
who will perform this work using
genuine parts and reset the system.
If the engine oil life system is ever
reset accidentally, service the vehicle
within 3,000 miles (5 000 km) since
the last service. Remember to reset
the oil life system whenever the oil is
changed. SeeEngine Oil Life
System on page 5-13for information
on the Engine Oil Life System and
resetting the system.
Maintenance Schedule 6-3
