COOLANT
The high-pressure cooling system has
a reservoir filled with year round anti‐
freeze coolant. The reservoir is filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and be‐ fore traveling to a colder climate.
CAUTION
•When the engine overheats fromlow engine coolant, suddenly add‐ing engine coolant may causecracks in the engine. To preventdamage, add engine coolant slowlyin small quantities.
•Do not drive with no engine cool‐ant. It may cause water pump fail‐ure and engine seizure, etc.
Checking the coolant level
WARNING
nRemoving radiator cap
•Never attempt to remove the radi‐ator cap while the engine is oper‐ating or hot. Doing so might leadto cooling system and engine dam‐age. Also, hot coolant or steamcould cause serious personal in‐jury.
•Turn the engine off and wait untilit cools down. Use extreme carewhen removing the radiator cap.Wrap a thick towel around it, andturn it counterclockwise slowly tothe first stop. Step back while thepressure is released from the cool‐ing system.When you are sure all the pressurehas been released, press down onthe cap, using a thick towel, andcontinue turning counterclockwiseto remove it.
(Continued)
(Continued)
•Even if the engine is not operating,do not remove the radiator cap orthe drain plug while the engine andradiator are hot. Hot coolant andsteam may still blow out underpressure, causing serious injury.
The engine coolant and/or inverter
coolant level is influenced by the hybrid system temperature. Before checking
or refilling the engine coolant and/or in‐
verter coolant, turn the hybrid vehicle off.
WARNING
The electric motor (cool‐ing fan) is controlled byengine coolant tempera‐ture, refrigerant pressureand vehicle speed. It maysometimes operate evenwhen the engine is notrunning.

WASHER FLUID
Checking the washer fluid level
0+'
The reservoir is translucent so that you
can check the level with a quick visual
inspection.
Check the fluid level in the washer fluid
reservoir and add fluid if necessary.
Plain water may be used if washer fluid is not available. However, use washer
solvent with antifreeze characteristics
in cold climates to prevent freezing.
WARNING
nCoolant
•Do not use radiator coolant or an‐tifreeze in the washer fluid reser‐voir.
•Radiator coolant can severely ob‐scure visibility when sprayed onthe windshield and may cause lossof vehicle control or damage topaint and body trim.
•Windshield washer fluid agentscontain some amounts of alcoholand can be flammable under cer‐tain circumstances. Do not allowsparks or flame to contact thewasher fluid or the washer fluidreservoir. Damage to the vehicle oroccupants could occur.
•Windshield washer fluid is poison‐ous to humans and animals. Donot drink and avoid contactingwindshield washer fluid. Seriousinjury or death could occur.

CLIMATE CONTROL AIR FILTER
Filter inspection
The climate control air filter should bereplaced according to the maintenance
schedule. If the vehicle is operated in
severely air-polluted cities or on dusty rough roads for a long period, it should
be inspected more frequently and re‐
placed earlier. When you replace the cli‐ mate control air filter, replace it per‐
forming the following procedure, and
be careful to avoid damaging other components.
0+'
1. Open the glove box and remove the stoppers on both sides.
0+'
2. With the glove box open, pull thesupport strap (1).
0+'
3. Remove the climate control air fil‐ter cover while pressing the lock on
the right side of the cover.
0+'
4. Replace the climate control air fil‐ ter.
5. Reassemble in the reverse order of disassembly.
NOTICE
When replacing the climate control
air filter install it properly. Other‐
wise, the system may produce noise
and the effectiveness of the filter
may be reduced.
