4-3. Do-it-yourself maintenance
CAUTION
The engine compartment contains many mechanisms and fluids that many move
suddenly, become hot, or become electrically energized. To avoid death or serious
injury:
■When working in the engine compartment:
●Keep hands, clothing, and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold and power steering
fluid reservoir, etc. right after driving as they may be hot. Oil and other fluids may
also be hot.
●Do not leave anything that may burn easily , such as paper or rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. 
Fuel and battery fumes are flammable.
●Be extremely cautious when working on the battery. 
It contains poisonous and corrosive sulfuric acid.
■When the engine is running
Perform maintenance checks with adequate ventilation
■When working near the electric cooling fan or radiator grill:
Be sure the ignition is off. With the igni tion on, th
e electric cooling fan may automat-
ically start to run if the air conditioning is on and/
or if the coolant temperature is
high. ( P.262 )
■When working on or under the vehicle:
●Do not get under the vehicle with just the jack supporting it. 
Always use automotive jack stands or other solid supports.
●Use eye protection to prevent flying or falling material, fluid spray, etc. from get -
ting in your eyes.

4-3. Do-it-yourself maintenance
CAUTION
■When inspecting and adjusting tire pressure
Be sure to reinstall the tire valve caps. 
Without the valve caps, dirt or moisture c
ould get into the valve and cause air leak-
age, which could result in an accident. If the caps ha
ve been lost, have new ones put
on as soon as possible.
■Check tire pressure regularly
The tire pressure warning system will warn you when one or more of your tires are
si
gnificantly under-inflated. However, ther e are combinations which the system will
not detect (both tires on the same side or same axle). Thus it is important to check
the tire pressure of all tires regularly.
■Proper inflation is critical to safe tire performance
Keep your tires properly inflated. Otherwise, the following conditions may occur
and r

esult in an accident causi ng in death or serious injury.
•Excessive wear
• Uneven wear
• Poor handling
• Possibility of blowouts from an overheated tire
• Poor sealing of the tire bead
• Wheel deformation and/or tire separation
• A greater possibility of tire damage from road hazards

Maintenance and care
■Changing interval for the front air conditioning filter
Inspect and replace the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, such as inner city or
desert areas, early replacement may be required. (For scheduled mainte -
nance information, please refer to the "Owner's Manual Supplement/Sched-
uled Maintenance".)
■If air flow decreases dramatically
The filter may be blocked. Check the filter and replace if necessary.
CAUTION
■Air purifier precautions
●Do not look into the xenon tube or directly expose your skin to the light in the
tube's light. The tube emits less than 300nm of ultraviolet light, however some
people may experience symptoms such as sore eyes, vision trouble, skin inflam-
mation, etc.
●Do not disassemble the air purifier. Some parts contain high voltage, and there is
also the possibility of causing a malfunction.
■ Resetting the air filter maintenance light data
After the replacement, the air filter maintenance light must be reset.
Push and hold the “OFF” button for
mor
e than 4 second.
