Continued
Maintenance
Engine Coolant
This coolant is premixed with 50% an tifreeze 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. Make sure the engine and radiator are cool.
2. Check the amount of coolant in the reserve
tank.
u If the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
2Engine Compartment Cover P. 583
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 about −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 for aluminum engines.
Continued use of any non-Ac ura 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. Th ey may not be compatible
with the coolant or with the engine components.
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.

If the specified br ake fluid is not av ailable, you should
use only DOT 3 or DOT 4 fluid from a sealed
container as a temporary replacement.
Using any non-Acura brake fl uid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and re filled with Acura Heavy

• Greater than 25 psi (175 kPa), but less
than front: 35 psi (240 kPa)/rear: 32 psi
(220 kPa):
Turn the air compressor on to inflate the
tire until the tire pressure reaches front: 35
psi (240 kPa)/rear: 32 psi (220 kPa).
• Greater than 25 psi (175 kPa), but less
than 35 psi (240 kPa):
Turn the air compressor on to inflate the

Then drive carefully for 10 more minutes or
until you reach the nearest service station,
whichever is sooner. Do not exceed 50 mph
(80 km/h). If you have not reached a service
station, stop and check the tire pressure.
u You should repeat this procedure as long
as the air pressure is within this range.
6. Unplug the kit from the accessory power
socket.
7. Unscrew the sealant/ai r hose from the tire
valve stem.
