Engine Air Cleaner/Filter
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter at the scheduled
maintenance intervals and replace it at the first oil
change after each 80 000 km (50,000 mi) interval. See
Scheduled Maintenance
on page 7‑3for more
information. If you are driving in dusty/dirty conditions,
inspect the filter at each engine oil change. Replace
filter if appears dusty or dirty.
How to Inspect the Engine Air Cleaner/
Filter
See Engine Compartment Overviewon page 6‑14for
the location of the engine air cleaner/filter.
To inspect the air cleaner/filter remove the filter from the
vehicle and lightly shake the filter to release loose dust
and dirt. If the filter remains caked with dirt, a new filter
is required. Never use compressed air to clean the filter.
Because this operation can be a little difficult, you may
choose to have this done at the dealer service
department.

To inspect or replace the filter, do the following:1. Disconnect the Mass Air Flow sensor, PCV hose, and both ducts.
2. Pull the entire system from the top of the engine.
3. Turn the system over and place it on a soft, non‐ abrasive surface.
4. Remove the screws that hold the housing and cover together and lift off the housing.
5. Inspect or replace the engine air cleaner/filter.
6. Reverse the steps to reinstall the system. Be sure to reinstall the housing tightly.
{WARNING:
Operating the engine with the air cleaner/filter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
flames if the engine backfires. Use caution when
working on the engine and do not drive with the
air cleaner/filter off.
Notice: If the air cleaner/filter is off, dirt can easily
get into the engine, which could damage it. Always
have the air cleaner/filter in place when you are
driving.
Automatic Transmission Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take your vehicle to a dealer and
have it repaired as soon as possible.
Change the fluid and filter at the intervals listed in the
Maintenance Schedule. See Scheduled Maintenance
on page 7‑3. Be sure to use the transmission fluid
listed in Recommended Fluids and Lubricantson
page 7‑8.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 7‑8.

Windshield wiper blades should be inspected for wear
or cracking. SeeScheduled Maintenanceon page 7‑3for more information on wiper blade inspection.
Replacement blades come in different types and are
removed in different ways. For the proper type and
length, seeMaintenance Replacement Parts
on
page 7‑10. Here's how to remove the wiper blade:
1. Pull the windshield wiper arm away from the windshield.
2. While holding the wiper arm, lift the clip up fromthe blade connecting point, and pull the blade
assembly down toward the windshield to remove
it from the wiper arm. 3. Install the new wiper blade on the wiper arm and
press down on the clip to snap it into place.
Backglass Wiper Blade Replacement

8. The driver side rear turn signal comes on toindicate that corner sensor is ready to be learned.
Proceed to the driver side rear tire, and repeat the
procedure in Step 5.

indicate the tire learning process is done. Turn the
ignition switch to LOCK/OFF.
If no tires are learned after entering the TPMS
learn mode, or if communication with the receiver
stops, or if the time limit has expired, turn the
ignition switch to LOCK/OFF and start over
beginning with Step 2.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.
Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle's tires, including the spare tire, for signs of
wear or damage. See When It Is Time for New
Tires
on page 6‑62for more information. Always remove the tires if any of the following
statements are true:
.You can see the indicators at three or more
places around the tire.
.You can see cord or fabric showing through
the tire's rubber.
.The tread or sidewall is cracked, cut,
or snagged deep enough to show cord or
fabric.
.The tire has a bump, bulge, or split.
.The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
Tires should be rotated every 12 000 km
(7,500 miles). See Scheduled Maintenance
on
page 7‑3
.
The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This will
ensure that your vehicle continues to perform
most like it did when the tires were new.

Maintenance Schedule
Introduction
Notice:Maintenance intervals, checks, inspections,
recommended fluids, and lubricants are necessary
to keep this vehicle in good working condition.
Damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
As the vehicle owner, you are responsible for the
scheduled maintenance in this section. We recommend
having your dealer perform these services. Proper
vehicle maintenance helps to keep the vehicle in good
working condition, improves fuel economy, and reduces
vehicle emissions for better air quality.
Because of all the different ways people use vehicles,
maintenance needs vary. The vehicle might need more
frequent checks and services. Please read the
information under Scheduled Maintenance. To keep the
vehicle in good condition, see your dealer.
The maintenance schedule is for vehicles that:
.carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
See Loading the Vehicle on page 5‑22.
.are driven on reasonable road surfaces within legal
driving limits.
.use the recommended fuel. See Gasoline Octaneon page 6‑6.
{WARNING:
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 to have a
qualified technician do the work. See Doing Your
Own Service Work on page 6‑4.
At your dealer, you can be certain that you will receive
the highest level of service available. Your dealer has
specially trained service technicians, uses genuine
replacement parts, as well as, up‐to‐date tools and
equipment to ensure fast and accurate diagnostics.
The proper replacement parts, fluids, and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 7‑8andMaintenance Replacement Partson
page 7‑10. We recommend the use of genuine parts
from your dealer.

Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed. Tires should be rotated every
12 000 km/7,500 miles. SeeTire Inspection and
Rotation on page 6‑60.
Scheduled Maintenance
When the Change Oil Soon Message
Displays
Change engine oil and filter. See Engine Oilon
page 6‑16. An Emission Control Service.
When the CHANGE OIL SOON message displays,
service is required for the vehicle as soon as possible,
within the next 1 000 km/600 miles. If driving under the
best conditions, the engine oil life system might not
indicate the need for vehicle service for more than a
year. The engine oil and filter must be changed at least
once a year and the oil life system must be reset. Your
dealer has trained service technicians who will perform
this work and reset the system. If the engine oil life
system is reset accidentally, service the vehicle within
5 000 km/3,000 miles since the last service. Reset the
oil life system whenever the oil is changed. See Engine
Oil Life System on page 6‑19.
When the Change Oil Soon message displays, certain
services, checks, and inspections are required.
