372Maintenance
Checking and Maintaining TiresChecking TiresTo 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 sp ecification’s 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 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 side of the tire. Re place it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have a dealer check the wheel alignment.
• Excessive tread wear.2 Wear Indicators P. 377
•Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been par ked 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.
Whenever tire pressure is adjusted, you must
calibrate the TPMS. 2 TPMS Calibration P. 322
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.

WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seri ously hurt or killed.
Follow all instruc tions in this owner’s
manual regarding tire inflation and
maintenance.U.S. models

Handling the Unexpected
OverheatingHow to Handle OverheatingOverheating symptoms are as follows:
•The high temperature indicator comes on or the engine suddenly loses power.
• Steam or spray comes out of the engine compartment.■First thing to do
1. Immediately park the vehicle in a safe place.
2. Turn off all accessories and turn on the hazard warning lights.
u No steam or spray present: Keep the engine running and open the hood.
u Steam or spray is present: Turn off the engine and wait until it subsides.
Then open the hood.
1 How to Handle OverheatingNOTICEContinuing to drive with the high temperature
indicator on may damage the engine.

WARNING
Steam and spray from an overheated
engine can seriously scald you.
Do not open the ho od if steam is coming
out.

408Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the high temperature
indicator goes off.
u If the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
u If the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.
u If there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.■Last thing to do
Once the engine has co oled sufficiently, restart it and check the high temperature
indicator.
If the high temperature indicator is off, resume driving. If it stays on, contact a dealer
for repairs.
1 How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emerge ncy/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.

WARNING
Removing the radiator 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 radiator cap.
