Maintenance
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 labe l or specification’s 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. 544
•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.
Whenever tire pressure is adjusted, you must
calibrate the TPMS. 2 TPMS Calibration P. 469
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.

Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge pointer comes down.
u If the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level an d check the cooling
system components for leaks.
u If the coolant level in the reserve tank is
low, or no coolant in the tank, check that
the radiator is cool. Cover the reserve
tank cap with a heavy cloth and open the
cap. Add coolant until it reaches the
MAX mark, and put the cap back on.
■Last thing to do
Once the engine has cooled sufficiently, restart it and check the temperature gauge.
If the temperature gauge pointer has gone do wn, resume driving. If it has not gone
down, contact a dealer for repairs.
1 How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergency/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
3WARNING
Removing the reserve tank cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the reserve tank
cap.
