Safety When Performing Maintenance
Some of the most important safety precau tions are given here. However, we cannot
warn you of every conceivable hazard that can arise in performing maintenance.
Only you can decide whether you should perform a given task.
• To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the 12-volt battery, all High Volt age system, and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them, causing a fire.
• To clean parts, use a co mmercially available degreas er or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the 12-volt
battery or compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if th ere is sufficient ventilation.

Maintenance
Cooling System
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.
3. Inspect the cooling system for leaks.
Specified coolant: Ac ura Long Life Antifreeze/Coolant Type 2
■Reserve Tank
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 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-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.
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.

Checking and Maintaining Tires
Checking Tires
To safely operate your vehicle, your tires must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
■Inflation guidelines
Properly inflated tires provide the best combination of handling, tread life, and
comfort. Refer to the driver’s doorjamb label or specifications page 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.
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/cm2) per month.
■Inspection guidelines
Every time you check inflation, also exam ine the tires and valve stems. Look for:
• Bumps or bulges on the side or in the tread. Replace the tire if you find any cuts,
splits, or cracks in the si de of the tire. Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have a deal er check the wheel alignment.
• Excessive tread wear.
2 Wear Indicators P. 525
•Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been parked for at least three
hours, or driven less than 1 mile (1.6 km). If
necessary, add or releas e air until the specified
pressure is reached.
If checked when hot, tire pressure can be as much as
4–6 psi (30–40 kPa, 0.3–0.4 kgf/cm
2) higher than if
checked when cold.
Have a dealer check the tires if you feel a consistent
vibration while driving. Ne w tires and any that have
been removed and reinst alled should be properly
balanced.
Check the spare tire pressu re once a month or before
long trips.
3WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instruction s in this owner’s
manual regarding ti re inflation and
maintenance.

uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
524
Maintenance
The traction grades, from highest to lowest, are AA, A, B, and C.
Those grades represent the tire’s ability to stop on wet pavement
as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked
C may have poor traction performance.
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of heat and its
ability to dissipate h eat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sustained high
temperature can cause the material of the tire to degenerate and
reduce tire life, and excessive temp erature can lead to sudden tire
failure. The grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than the minimum
required by law.
■Traction
■Temperature
1 Traction
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
1Temperature
Warning: The temperature grade for
this tire is establishe d for a tire that is
properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.

Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the sa me size, load range, speed rating, and
maximum cold tire pressure ra ting (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause ce rtain vehicle systems such as the ABS and
Vehicle Stability Assist
TM (VSA ®) system 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 replace a wheel, only use TPMS sp ecified wheels approved for your vehicle.
Make sure that the wheel’s specifications match thos e of the original wheels.
