●Inspect fuel lines and connections#*3: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and
from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).
*4: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission and transfer temperatures. This requires transmission and transfer fluid changes more frequently than
recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have
the transmission fluid changed at 60,000 miles (100,000 km), then every 30,000 miles (48,000 km).
*5: If you drive regularly in very high temperatures (over 110 °F, 43 °C), in very low temperatures (under -
20 °F, -29 °C), replace every 60,000 miles/100,000 km.

uuMaintenance Under the Hood uEngine Coolant
Maintenance
Engine Coolant
This coolant is premixed with 50% antifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the engine coolant level every time you refuel. Check the
reserve tank first. If it is completely empty, also check the coolant level in the
radiator. Add the engine coolant accordingly.
1.Check the amount of coolant in the reserve
tank.
2. If the coolant level is below the MIN mark,
add the specified coolant until it reaches
the MAX mark.
3. Inspect the cooling system for leaks.
Specified coolant: Acura Long Life Antifreeze/Coolant Type 2
■Reserve Tank
1Engine Coolant
NOTICE
Genuine Acura engine cool ant is a 50/50 mixture of
antifreeze and water that can withstand freezing at
temperatures as low as a bout -31°F (-35°C). If your
vehicle is consistently subjected to temperatures
below this, the concentration of antifreeze in the
coolant should be increased. Consult a dealer for
details.
If Acura antifreeze/coolant is not available, you may
use another major brand non- silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended for aluminum engines.
Continued use of any non-Acur a coolant can result in
corrosion, causing the cooling system to malfunction
or fail. Have the cooling system flushed and refilled
with Acura antifreeze/cool ant as soon as possible.
Do not add rust inhibitors or other additives to your
vehicle’s cooling system. They may not be compatible
with the coolant or with the engine components.

uuOverheating uHow to Handle Overheating
Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle 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 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 cooled sufficiently, re start it and check the temperature gauge.
If the temperature needle has gone down, 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 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.
