install a new oil filter.
u Apply a light coat of new engine oil to
the filter gasket.
1Changing the Engine Oil and Oil Filter
NOTICE
You may damage the environment if you do not
dispose of the oil in a suitable way. If you are
changing the oil by yourself , appropriately dispose of
the used oil. Put the oil in a sealed container and take
it to a recycling center. Do not throw the oil away
into a garbage can or onto the ground.
You will need a special wrench to replace the oil
filter. You can buy this wrench from a dealer.
When installing the new oil filter, follow the
instructions supplied with the oil filter.
Reinstall the engine oil fill cap. Start the engine. The
low oil pressure indicator should go off within five

Checking and Maintaining Tires
Checking Tires
To safely operate your vehicle, your tires must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
■Inflation guidelines
Properly inflated tires provide the best combination of handling, tread life, and
comfort. Refer to the driver’s doorjamb label or specifications page for the specified
pressure.
Underinflated tires wear unevenly, adversely affect handling and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride harshly, are more prone to road hazards,
and wear unevenly.
Every day before you drive, look at each of the tires. If one looks lower than the
others, check the pressure with a tire gauge.
At least once a month or before long trips, use a gauge to measure the pressure in
all tires, including the spare
*. Even tires in good condition can lose 1-2 psi (10-20
kPa, 0.1-0.2 kgf/cm2) per month.
■Inspection guidelines
Every time you check inflation, also exam ine the tires and valve stems. Look for:
• Bumps or bulges on the side or in the tread. Replace the tire if you find any cuts,
splits, or cracks in the si de of the tire. Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have a deal er check the wheel alignment.
• Excessive tread wear.
2 Wear Indicators P. 525
•Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been parked for at least three
hours, or driven less than 1 mile (1.6 km). If
necessary, add or releas e air until the specified
pressure is reached.
If checked when hot, tire pressure can be as much as
4–6 psi (30–40 kPa, 0.3–0.4 kgf/cm
2) higher than if
checked when cold.
Have a dealer check the tires if you feel a consistent
vibration while driving. Ne w tires and any that have
been removed and reinst alled should be properly
balanced.
Check the spare tire pressu re once a month or before
long trips.
3WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instruction s in this owner’s
manual regarding ti re inflation and
maintenance.

uuChecking and Maintaining Tires uWear Indicators
Maintenance
Wear Indicators
The groove where the wear indicator is
located is 1/16 inch (1.6 mm) shallower than
elsewhere on the tire. If the tread has worn so
that the indicator is ex posed, replace the tire.
Worn out tires have po or traction on wet
roads.
Tire Service Life
The life of your tires is dependent on many factors, including driving habits, road
conditions, vehicle loading, inflation pressure, maintenance history, speed, and
environmental conditions (even wh en the tires are not in use).
In addition to regular inspections and in flation pressure maintenance, it is
recommended that you have annual inspections performed once the tires reach five
years old. All tires, including the spare
*, should be removed from service after 10
years from the date of manufacture, regardle ss of their condition or state of wear.
1Checking Tires
High speed driving
We recommend that you do not drive faster than the
posted speed limits and condi tions allow. If you drive
at sustained high speeds (over 118 mph or 190
km/h), adjust the cold tire pressures as shown below
to avoid excessive heat build up and sudden tire
failure.

Emergency Power System Off
The POWER button may be used to turn the power system off due to an emergency
situation even while driving. If you must tu rn the power system off, do either of the
following operations:
• Press and hold the POWER button for about two seconds.
• Firmly press the POWER button three times.
The steering wheel will not lock. However, because turning off the engine disables
the power assist the engine provides to the steering and braking systems, it will
require significantly more physical effort an d time to steer and slow the vehicle. Use
both feet on the brake pedal to slow down the vehicle and stop immediately in a
safe place.
The gear position auto matically changes to
(P after the vehicle comes to a complete
stop. Then, the power mode changes to VEHICLE OFF.

Information
Emissions Testing
Testing of Readiness Codes
Your vehicle has readiness codes as part of the onboard self diagnostic system.
Some States use these codes for testing to verify whether your vehicle’s emissions
components are working properly.
The codes may not be read properly if te sting is performed just after the 12-volt
battery has gone dead or been disconnected.
To check if they are set, set the powe r mode to ON, without turning the power
system on. The malfunction indicator lamp will come on for several seconds. If it
then goes off, the readiness co des are set. If it blinks five times, the readiness codes
are not set.
If you are required to have your vehicle te sted before the readiness codes are ready,
prepare the vehicle for retest ing by doing the following:
1. Fill the gas tank to approximately 3/4 full.
2. Park the vehicle and leave the power system off for 6 hours or more.
3. Make sure the ambient temperature is between 40°F and 95°F (4°C and 35°C).
4. Turn the power system on.1Testing of Readiness Codes
The readiness codes are erased when the 12-volt
battery is disconnected, and set again only after
several days of driving unde r a variety of conditions.
If a testing facility determines that the readiness
codes are not set, you may be requested to return at
a later date to complete the test.
If the testing facility determines the readiness codes
are still not set, see a dealer.
