Checking Wiper Blades
If the wiper blade rubber has deteriorated, it will leave streaks and the metal wiper
arm may scratch the window glass.
Changing the Wiper Blade Rubber
1.Lift the driver side wiper arm first, then the
passenger side.
2. Place a cloth on the ed ge of the lock tab.
Push the lock tab up with a flat-tip screw
driver.
3. Slide the blade from the wiper arm.

5. Remove the retainers from the rubber blade
that has been removed, and mount to a
new rubber blade.

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 comb ination of handling, tread life, and comfort.
Refer to the driver’s doorjamb label or spec ification’s page for the specified pressure.
Underinflated tires wear unevenly, adversel y 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 pressu re with a tire gauge.
At least once a month or before long trip s, use a gauge to measure the pressure in
all tires, including the spare. Even tires in good condition can lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf/cm
2) 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 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. 305
•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
release 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. New tires and any that have
been removed and reinstalled should be properly
balanced.
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.
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 instructions in this owner’s
manual regarding tire inflation and
maintenance.

Tire and Loading Information Label
The label attached to the driver’s doorja mb provides necessary tire and loading
information.
Tire Labeling
The tires that came on your vehicle have a
number of markings. Those you should be
aware of are described below.
Whenever tires are replaced, they should be replaced with tires of the same size.
1Tire and Loading Information Label
The tire and loading informat ion label attached to the
driver’s doorjamb contains:
aThe number of people your vehicle can carry.bThe total weight your vehicle can carry. Do not
exceed this weight.
cThe original tire sizes for front, rear, and spare.dThe proper cold tire pressure for front, rear, and
spare.

Following is an example of tire size with an
explanation of what each component means.
P255/50 R19 103H
P: Vehicle type (P indi cates passenger vehicle).
255: Tire width in millimeters.
50: Aspect ratio (the tire’s section height as a
percentage of its width).
R: Tire construction code (R indicates radial).
19: Rim diameter in inches.
103: Load index (a numerical code associated with
the maximum load the tire can carry).
H: Speed symbol (an alphab etical code indicating the
maximum speed rating).

The tire identification number (TIN) is a gr oup of numbers and letters that look like
the example in the side column. TIN is located on the sidewall of the tire.
Cold Tire Pressure – The tire air pressure when the vehicle has been parked for at
least three hours or driven less than 1 mile (1.6 km).
Load Rating – Means the maximum load that a ti re is rated to carry for a given
inflation pressure.
Maximum Inflation Pressure – The maximum tire air pressure that the tire can
hold.
Maximum Load Rating – Means the load rating for a tire at the maximum
permissible inflation pr essure for that tire.
Recommended Inflation Pressure – The cold tire inflation pressure recommended
by the manufacturer.
Treadwear Indicators (TWI) – Means the projections within the principal grooves
designed to give a visual indication of the degrees of wear of the tread.
