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

high-quality tires made by a
leading tire manufacturer. If you
ever have questions about your
tire warranty and where to obtain
service, see your vehicle
Warranty booklet for details. For
additional information refer to the
tire manufacturer.
{CAUTION
Poorly maintained and
improperly used tires are
dangerous.
Overloading your
vehicle’s tires can cause
overheating as a result of
too much exing. You
could have an air-out and
a serious accident. See

4. Start with the driver side
front tire.
5. Remove the valve cap from the
valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire’s air pressure
for ve seconds, or until a horn
chirp sounds. The horn chirp,
which may take up to 30 seconds
to sound, conrms that the sensor
identication code has been
matched to this tire and wheel
position.
6. Proceed to the passenger side
front tire, and repeat the
procedure in Step 5.7. Proceed to the passenger side
rear tire, and repeat the
procedure in Step 5.
8. Proceed to the driver side rear

Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire, if
the vehicle has one, for signs of
wear or damage. SeeWhen It Is
Time for New Tires on page 5-50
for more information.
Tires should be rotated every
5,000 to 8,000 miles (8 000 to
13 000 km). SeeScheduled
Maintenance on page 6-3.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new.
Any time you notice unusual
wear, rotate the tires as soon
as possible and check wheel
alignment. Also check for
damaged tires or wheels.

Maintenance Schedule 6-1

Maintenance
Requirements
Notice:Maintenance intervals,
checks, inspections, replacement
parts, and recommended uids
and lubricants as prescribed
in this manual are necessary to
keep this vehicle in good working
condition. Any damage caused
by failure to follow scheduled
maintenance might not be
covered by the vehicle warranty.
Your Vehicle and the
Environment
Proper vehicle maintenance not only
helps to keep the vehicle in good
working condition, but also helps the
environment. All recommended
maintenance is important. Improper
vehicle maintenance can even
affect the quality of the air we
breathe. Improper uid levels or the
wrong tire ination can increase
the level of emissions from the
vehicle. To help protect theenvironment, and to keep the
vehicle in good condition, be sure to
maintain the vehicle properly.
Using the Maintenance
Schedule
We want to help keep this vehicle in
good working condition. But we
do not know exactly how you
will drive it. You might drive very
short distances only a few times a
week. Or you might drive long
distances all the time in very hot,
dusty weather. You might use
the vehicle in making deliveries. Or
you might drive it to work, to do
errands, or in many other ways.
Because of all the different
ways people use their vehicles,
maintenance needs vary. You might
need more frequent checks and
replacements. So please read the
following and note how you
drive. If you have any questions on
how to keep the vehicle in good
condition, see your dealer/retailer.This schedule is for vehicles that:
carry passengers and cargo
within recommended limits on the
Tire and Loading Information
label. SeeLoading the Vehicle on
page 4-16.
are driven on reasonable road
surfaces within legal driving
limits.
use the recommended fuel. See
Gasoline Octane on page 5-5.
The services inScheduled
Maintenance on page 6-3should be
performed when indicated. See
Additional Required Services
on page 6-6andMaintenance
Footnotes on page 6-7for further
information.
6-2 Maintenance Schedule

{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

When the CHANGE ENGINE OIL

in some cases, Maintenance II
may be required more often.
