Maintenance
Inverter Coolant
This coolant is premixed with 50% antifreeze and 50% water. Do not add any
straight antifreeze or water.
We recommend you check the inverter co olant level every time you refuel.
Have a dealer replace the inverter coolant.
1.Check the fluid level in the tank.
2. If the coolant level has dropped below the
MIN level, have your vehicle serviced at a
dealer.
u Only a properly trained technician can
refill the coolant an d check the system
for leaks.
Specified coolant: Acura Long Life Antifreeze/Coolant Type 2
■Checking the Coolant
1Inverter 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 of non-silicate coolant as a
temporary replacement. Check that it is a high quality
coolant recommended fo r aluminum engines.
Continued use of any non-Acur a coolant can result in
corrosion, causing the coo ling 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 motor components.

uuCleaning uExterior Care
536
Maintenance
• Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. Standing too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.

Chemical solvents and st rong cleaners can damage
the paint, metal, and plasti c on your vehicle. Wipe
away spills immediately.
1 Maintaining the Bumpers an d Other Resin Coated Parts
Ask a dealer about the corr ect coating material when
you want to repair the pa inted surface of the parts
made of resin.

Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
turn the power system off once the high
temperature indicator goes off.
u If the cooling fan is not operating,
immediately turn the power system off.
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.
2 Radiator P. 511
■Last thing to do
Once the engine has cooled sufficiently , turn the power system on and check the
high temperature indicator. If the high temp erature 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.
