n Resetting the Engine Oil Life
If you change or
replace the vehicle’s engine oil yourself, you must reset the engine oil
life. Use the right selector wheel on the steering wheel to make selections in the driver
information interface.
Whee lRight Selector
Set the power mode to ON. Roll the wheel until the oil life displays in the driver information
interface.
Press the wheel for at least 10 seconds, until you enter reset mode.
Select All Items Due, then press the wheel. The maintenance items disappear, and the
engine oil life display returns to 100%.
Failure to reset the engine oil life after a maintenance service results in the system showing
incorrect maintenance intervals, which can lead to serious mechanical problems.
NOTICE
Engine Coolant
Park the vehicle on level ground. Check the reserve tank and the coolant level in the radiator.
We specify Acura Long Life Antifreeze/Coolant Type 2.
n
Checking the Coolant Lev

el
Open the hatch and remove the driver’s side engine cover (see
page 183).
If the coolant level in the reserve tank is below the MIN mark,
add the specified coolant until it reaches the MAX mark.
Inspect the cooling system for leaks.
Reserve Tank MAXMIN
If temperatures consistently below −22°F (−30°C) are expected, the coolant mixture should
be changed to a higher concentration. Consult your authorized Acura NSX dealer for more
information.

n Adding Coolant
Make sure
the engine and radiator are cool.
Turn the reserve tank cap counterclockwise and relieve any
pressure in the coolant system. Do not push the cap down
when turning.
Push down and turn the cap counterclockwise to remove it.
Pour coolant into the reserve tank until it reaches the MAX
mark. Put the cap back on the reserve tank and tighten.
Reserve Tank
Cap
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.
WARNING
Pour the fluid slowly and carefully so you do not spill any. Clean up any spills immediately;
they can damage components in the engine compartment.

Checking the Inverter

Coolant Level
Open the hood.
If the inverter coolant is below the MIN level, have your
vehicle serviced at an authorized Acura NSX dealer.

Brake Fluid
The fluid level should be between the MIN and MAX marks on
the side of the reservoir. We recommend using Acura Heavy
Duty Brake Fluid DOT 4.
Pour the fluid carefully.
If the fluid level is at or below the MIN mark, have the vehicle
inspected for leaks or worn brake pads as soon as possible.

Brake fluid marked DOT 5 is not compatible with your vehicle’s braking system and can cause
extensive damage.
NOTICE
Checking the 12-Volt Battery
Check the battery terminals for corrosion monthly.
Remove the cover by pressing the tabs. Slide the terminal cover
over the (+) terminal.
AGM-labeled batteries can be damaged if improperly charged.

The battery gives off explosive hydrogen gas during normal operation.
A spark or flame can cause the battery to explode with enough force to kill or
seriously hurt you.
When conducting any battery maintenance, wear protective clothing and a face
shield, or have a skilled technician do it.
WARNING
WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds.
Wash your hands after handling.
Changing Wiper Blades
If the wiper blades leave streaks across the windshield, try cleaning them first with a paper towel
or soft cloth and wiper fluid. If the wiper blade rubber has deteriorated, you should change the
wiper blades.
1.
Hold the wiper switch in MIST as y

ou change the power
mode to VEHICLE OFF (LOCK). The wiper arms will move into
the service position.
2. Lift both wiper arms.
3. For each wiper, press and hold the tab, then slide the wiper
blade holder out fr om the wiper arm.

NOTICE
Tire Information
To safely operate your vehicle, your tires must be of the proper type and size, in good condition
with adequate tread, and properly inflated.
n
Inflation Guidelines
Properly inflated tir

es provide the best combination of handling, tread life, and comfort.
Refer to the driver’s doorjamb label or the specifications (see page 127) for the specified
pressure.
Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are
more likely to fail from overheating.
Overinflated tires make your vehicle ride harshly, are more prone to road hazards, and wear
unevenly.
Every day before you drive, look at each of the tires. If one looks lower than the others,
check the pressure with a tire gauge.
Measure the air pressure when tires are cold. This means the vehicle has been parked for at
least 3 hours, or driven less than 1 mile (1.6 km). If necessary, add or release air until the
specified pressure is reached. If checked when hot, tire pressure can be as much as 4-6 psi
(30-40 kPa, 0.3-0.5 kgf/cm
2) higher than checked when cold.
At least once a month or before long trips, use a gauge to measure the pressure in all tires,
including the spare. Even tires in good condition can lose 1-2 psi
(10-20 kPa, 0.1-0.2 kgf/cm
2) per month.

n Inspection Guidelines
Every time you inflate the tir
es, check for the following:
•
Any damage to

tires, including bumps, bulges, cuts, splits, or cracks in the side or tread.
Remove any foreign objects and inspect for air leaks. Replace tires if you see fabric or cord.
•
Uneven or excessiv

e tread wear. Have an authorized Acura NSX dealer check the wheel
alignment.
•
Cracks or other damage around the val

ve stems.
n
Wear Indicators
The groov

e where the wear indicator is located is 1/16 inch
(1.6 mm) shallower than elsewhere on the tire. If the tread
has worn so low that the indicator is exposed, replace the tire.
Worn out tires have poor traction on wet roads.
Example of a wear indicator mark
Using tires that are excessively worn or improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instructions in this owner’s manual regarding tire inflation and
maintenance.

driver’s doorjamb provides necessary tire and loading
information.

n Tire and Wheel Replacement
Replace y
our tires with radials of the same size, load range, speed rating, and maximum
cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a different size or
construction can cause certain vehicle systems to work incorrectly. It is best to replace all
four tires at the same time. If that isn’t possible, replace the front or rear tires in pairs.
If you change or replace a wheel, make sure that the wheel’s specifications match those of
the original wheels. Only use TPMS-specified wheels approved for your vehicle.
Installing improper tires on your vehicle can affect handling and stability.
This can cause a crash in which you can be seriously hurt or killed.
Always use the size and type of tires recommended in the owner’s manual.
WARNING
n Tire Service Life
The life of y
our tires is dependent on many factors, including driving habits, road conditions,
vehicle loading, inflation pressure, maintenance history, speed, and environmental
conditions (even when the tires are not in use).
In addition to regular inspections and inflation pressure maintenance, it is recommended
that you have annual inspections performed once the tires reach five years old. All tires,
including the spare, should be removed from service after 10 years from the date of
manufacture, regardless of their condition or state of wear. n
Winter Tires
If driving on snowy

or frozen roads, mount all season tires marked “M+S”, snow tires, or
tire chains; reduce speed; and maintain sufficient distance between vehicles when driving.
For winter tires, select the size and load ranges that are the same as the original tires, and
mount them to all four wheels.
n
Tire Chains
Tire chains can be used onl
y in conjunction with winter tires. Install tire chains on the rear
tires only.
For 295/30R20 (97V) winter tires: Auto-trac 232405
For 305/30R20 (103W) XL winter tires: K-Summit K-44
Mount chains as tightly as you can, and make sure that they do not touch the brake lines or
suspension.
Using the wrong chains, or not properly installing chains, can damage the brake
lines and cause a crash in which you can be seriously injured or killed.
Follow all instructions in this guide regarding the selection and use of tire chains.
WARNING
Traction devices that are the wrong size or improperly installed can damage your vehicle’s
brake lines, suspension, body, and wheels. Stop driving if they are hitting any part of the
vehicle.
