Auto Engine Stop/Start
Your vehicle’s gasoline engine will automatically stop and start during vehicle operation as needed to meet driving and battery conditions.
These are some examples that could cause the gasoline engine to automatically start.
In the following cases, however, Auto Engine Stop may not activate. ● When the Integrated Dynamics System is in SPORT+ mode or TRACK mode.
● The vehicle momentarily needs additional power for aggressive acceleration, or driving uphill or at high speed.
● The climate control system is in heavy use.
● The High Voltage battery temperature is high or low.
● The High Voltage battery state of charge is low.
● The engine coolant temperature is low.
● When the door is opened after releasing seatbelt.
● When the shift position is in M (Manual) mode.

■ASSIST/CHARGE Gauge
1Temperature Gauge
Driving with the temperat ure gauge pointer in the
upper zone can cause serious engine damage. Pull
safely to the side of th e road and allow engine
temperature to return to normal. 2 Overheating P. 450
1High Voltage Battery Charge Level Gauge
The High Voltage battery ch arge level may decrease
under the following conditions: • When the 12-volt battery has been replaced.
• When the 12-volt battery has been disconnected.
• When the High Voltage battery control system
corrects its reading.
The charge level readi ng will be corrected
automatically while driving.
Changes in the temperature of the High Voltage
battery can increase or decrease the battery’s
charging capacity. If temp erature changes cause the
battery’s capacity to change, the number of
indicators in the battery ch arge level gauge may also
change, even if the amount of charging remains the
same.

*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 filters every 15,000 miles (24,000 km) or every year.
*4: Driving in mountainous areas at very low vehicle speeds results in higher transmission temperature. This requires transmission fluid and clutch fluid changes more frequently than recommended by the
Maintenance Minder. If you regularly drive your vehicle under this condition, have the transmission
fluid and clutch fluid changed every 20,000 miles (32,000 km).
*5: Driving in mountainous areas at very low vehicle speeds results in higher level of mechanical (Shear) stress to fluid. This requires Twin Motor Unit fluid changes more frequently than recommended by the
Maintenance Minder. If you regularly drive your vehicle under these conditions, have the Twin Motor
Unit fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

Cooling System
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. Add the engine coolant accordingly.1. Make sure the engine and radiator are cool.
2. Open the hatch.
2 Opening the Hatch P. 387
3. Remove the left engine compartment
cover.
2 Engine Compartment Cover P. 389
4. Check the amount of c oolant in the reserve
tank.
uIf the coolant level is below the MIN
mark, add the specified coolant until it
reaches the MAX mark.
5. Inspect the cooling system for leaks.
Specified coolant: Acura Long Life Antifreeze/Coolant Type 2
■Checking the Coolant
1Cooling System
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 an authorized
Acura NSX 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 reserve tank 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 reserve tank
cap.

Have an authorized Acura NSX deal er replace the inverter coolant.
1. Open the hood.
2 Opening the Hood P. 388
2. Check the fluid level in the tank.
3. If the coolant level has dropped below the
MIN level, have your vehicle serviced at an
authorized Acura NSX dealer.
uOnly a properly trained technician can
refill the coolant an d check the system
for leaks.

Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
turn the power system off once the
temperature gauge pointer comes down.
uIf the cooling fan is not operating,
immediately turn the power system off.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
2 Checking the Coolant P. 396
uIf the coolant level in the reserve tank is
low, or no coolant in the tank, check that
the radiator is cool. Cover the reserve
tank cap with a heavy cloth and open the
cap. Add coolant until it reaches the MAX mark, and put the cap back on.
■ Last thing to do
Once the engine has cooled sufficiently, turn the power system on and check the
temperature gauge. If the temperature gauge pointer has gone down, resume
driving. If it has not gone down, contact an authorized Acura NSX dealer for repairs.
1How to Handle Overheating
If the coolant is leaking, contact an authorized Acura
NSX dealer for repairs.
Use water as an emergency/temporary measure only.
Have an authorized Acura NSX dealer flush the
system with proper antifree ze as soon as possible.
3WARNING
Removing the reserve tank cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
