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 specifications 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/cm
2) per month.
1 Checking 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.
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.

Maintenance
Heating and Cooling System*/Climate Control System* Maintenance
Air Conditioning
To ensure proper and safe operation, the Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant sy stem only be serviced by trained and
certified technicians.
Never repair or replace the air conditioning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filter
The heating and cooling system*/climate control system* is equipped with a dust
and pollen filter that collects pollen, dust, and other debris in the air. The
Maintenance Minder
TM messages will let you know when to replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.

Overheating
How to Handle Overheating
Overheating symptoms are as follows:
•The high temperature indicator (red) co mes 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.

NOTICE
Continuing to drive with the high temperature
indicator on may da mage the engine.
3WARNING
Steam and spray from an overheated
engine can seriously scald you.
Do not open the hood if steam is coming

Handling 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 an d 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 coolan t 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 cooled 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 emergency/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
3WARNING
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.MAX
