How to Reset the Engine Oil Life
System
Reset the system whenever the engine oil is changed
so that the system can calculate the next engine oil
change. To reset the system:1. Turn the ignition to ON/RUN, with the engine off.
2. Press the DIC INFO button until OIL LIFE REMAINING displays. See DIC Operation and
Displays on page 4‑60.
3. Press and hold the DIC INFO RESET button until 100% displays.
4. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOON message comes
back on when the vehicle is started, the engine oil life
system has not been reset. Repeat the procedure.
Engine Air Cleaner/Filter
See Engine Compartment Overviewon page 6‑14for
the location of the 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 50,000 mile (80 000 km) 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.
How to Inspect 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.

Power Steering Fluid
The power steering fluid
reservoir is located next to
the underhood fuse block
on the passenger side of
the vehicle. SeeEngine
Compartment Overview
on page 6‑14for more
information on location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
To check the power steering fluid:
1. Turn the key off and let the engine compartment cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a clean rag. 4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the fluid level
on the dipstick.
The level should be at the FULL COLD mark.
If necessary, add only enough fluid to bring the level
up to the mark.
What to Use
To determine what kind of fluid to use, see
Recommended Fluids and Lubricantson page 7‑9.
Always use the proper fluid.
Notice: Use of the incorrect fluid may damage the
vehicle and the damages may not be covered by the
vehicle's warranty. Always use the correct fluid
listed in Recommended Fluids and Lubricants
on
page 7‑9.
Windshield Washer Fluid
What to Use
When the vehicle needs windshield washer fluid, be
sure to read the manufacturer's instructions before use.
If the vehicle will be operating in an area where the
temperature may fall below freezing, use a fluid that has
sufficient protection against freezing.

.One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your dealer
for service.
.Replacement tires or wheels do not match your
vehicle's original equipment tires or wheels.
Tires and wheels other than those recommended
for your vehicle could prevent the TPMS from
functioning properly. SeeBuying New Tires
on
page 6‑68.
.Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or signal
a low tire condition. See your dealer for service if the
TPMS malfunction light and DIC message comes on
and stays on.
TPMS Sensor Matching Process
Each TPMS sensor has a unique identification code.
Any time you rotate your vehicle's tires or replace
one or more of the TPMS sensors, the identification
codes will need to be matched to the new tire/wheel
position. The sensors are matched to the tire/wheel
positions in the following order: driver side front tire,
passenger side front tire, passenger side rear tire, and
driver side rear tire using a TPMS diagnostic tool. See
your dealer for service.
The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing the tire's
air pressure. If increasing the tire's air pressure, do not
exceed the maximum inflation pressure indicated on the
tire's sidewall.
To decrease air-pressure out of a tire you can use the
pointed end of the valve cap, a pencil-style air pressure
gauge, or a key.
You have two minutes to match the first tire/wheel
position, and five minutes overall to match all four tire/
wheel positions. If it takes longer than two minutes, to
match the first tire and wheel, or more than five minutes
to match all four tire and wheel positions the matching
process stops and you need to start over.

The TPMS sensor matching process is outlined below:1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the engine off.
3. Press the Remote Keyless Entry (RKE) transmitter's lock and unlock buttons at the same
time for approximately five seconds. The horn
sounds twice to signal the receiver is in relearn
mode and TIRE LEARNING ACTIVE message
displays on the DIC screen.
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 five seconds,
or until a horn chirp sounds. The horn chirp, which
may take up to 30 seconds to sound, confirms that
the sensor identification 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 tire, and repeat the procedure in Step 5. The horn sounds two times to
indicate the sensor identification code has been
matched to the driver side rear tire, and the TPMS
sensor matching process is no longer active. The
TIRE LEARNING ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
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.

Parking Brake and Automatic
Transmission P (Park) Mechanism
Check
{WARNING:
When you are doing this check, the vehicle could
begin to move. You or others could be injured and
property could be damaged. Make sure there is
room in front of the vehicle in case it begins to
roll. Be ready to apply the regular brake at once
should the vehicle begin to move. Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake, set the
parking brake.
.To check the parking brake's holding ability: With
the engine running and the transmission in
N (Neutral), slowly remove foot pressure from the
regular brake pedal. Do this until the vehicle is held
by the parking brake only.
.To check the P (Park) mechanism's holding ability:
With the engine running, shift to P (Park). Then
release the parking brake followed by the regular
brake.
Contact your dealer if service is required.
