1. Make sure the engine and radiator are
cool.
2. Turn the radiator cap 1/8 turn counter-
clockwise and relieve any pressure in the
coolant system.
3. Push down and turn the radiator cap
counter-clockwise to remove it.
4. The coolant level should be up to the base
of the filler neck. Add coolant if it is low.
5. Put the radiator cap back on, and tighten it
fully.

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 provid e the best combination of hand ling, tread life, and comfort.
Refer to the driver’s doorjamb label or spec ifications page for the specified pressure.
Underinflated tires wear unev enly, adversely affect handling and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, 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 examine the tires and valve stems.
Look for:
• Bumps or bulges on the side or in the tr ead. Replace the tire if you find any cuts,
splits, or cracks in the side 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. 500
•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. 2 Tire Fill Assist P. 425
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 tire 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 poor 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 pre ssure, maintenance history, speed, and
environmental conditions (even when the tires are not in use).
In addition to regular in spections and inflation pres sure maintenance, it is
recommended that you have annual inspecti ons 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, regard less 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 conditions allow. If you drive
at sustained high speeds (over 99 mph or 160 km/h),
adjust the cold tire pressures as shown below to
avoid excessive heat build up and sudden tire failure.
