uuRefueling uHow to Refuel
Driving
How to Refuel
1. Stop your vehicle with the service station
pump on the left side of the vehicle in the
rear.
2. Turn off the engine.
3. Press the fuel fill door release button.
u The fuel fill door opens.
4. Remove the fuel fill cap slowly. If you hear a
release of air, wait until this stops, then turn
the knob slowly to open the fuel fill cap.
5. Place the fuel fill cap in the holder.
6. Insert the filler nozzle fully.
u When the tank is full, the filler nozzle will
click off automatically. This leaves space
in the fuel tank in case the fuel expands
with a change in the temperature.
7. After filling, replace the fuel fill cap,
tightening it until you hear it click at least
once.
u Shut the fuel fill door by hand.
1How to Refuel
The filler nozzle automatically stops to leave space in
the fuel tank so that fuel does not overflow as a result
of changes in air temperature.
If the fuel filler nozzle keeps turning off when the
tank is not full, there may be a problem with the
pump’s fuel vapor recovery system. Try filling at
another pump. If this does not fix the problem,
consult a dealer.
Do not continue to add fuel af ter the nozzle has
automatically stopped. Additional fuel can exceed
the full tank capacity.

WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured
when handling fuel.
• Stop the engine, and keep heat, sparks,
and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.

Accessories and ModificationsAccessoriesWhen installing accessories, check the following:
•Do not install accessories on the windshield. They can obstruct your view and
delay your reaction to driving conditions.
• Do not install any accessories over areas marked SRS Airbag, on the sides or backs
of the front seats, on front or side pillars, or near the side windows. Accessories
installed in these areas may interfere with proper operation of the vehicle’s
airbags or may be propelled into you or an other occupant if the airbags deploy.
• Be sure electronic accessories do not overload electrical circuits or interfere with
proper operation of your vehicle.
2 Fuses P. 474
•Before installing any electronic accessory, have the installer contact a dealer for
assistance. If possible, have a dealer inspect the final installation.ModificationsDo not modify your vehicle or use non-Acura components that can affect its
handling, stability, and reliability.
Overall vehicle performance can be affected. Always make sure all equipment is
properly installed and maintained, and that it meets federal, state, province,
territory, and local regulations.
1Accessories and Modifications
Acura Genuine accessories are recommended to
ensure proper operation on your vehicle.

WARNING
Improper accessories or modifications can
affect your vehicle’s handling, stability, and
performance, and cause a crash in which
you can be seriously hurt or killed.

Maintenance
Safety When Performing MaintenanceSome of the most important safety precautions are given here.
However, we cannot warn you of every conc eivable hazard that can arise in
performing maintenance. Only you can decide whether or not you should perform
a given task.
• To reduce the possibility of fire or explosion, keep cigarettes, sparks, and flames
away from the battery 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 commercially available degreaser or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the battery or
compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if there is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on level ground, the parking brake is set, and
the engine is off.
• Be aware that hot parts can burn you.
u Make sure to let the engine and exhaust system cool thoroughly before
touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not start the engine unless instructed, and keep your hands and limbs away
from moving parts.■

1. Make sure the engine and radiator are
cool.
2. Remove the engine compartment cover.

3.Turn the radiator cap counterclockwise and
relieve any pressure in the coolant system.
Do not push the cap down when turning.
4. Push down and turn the radiator cap
counterclockwise to remove it.
5. The coolant level should be up to the base
of the filler neck. Add coolant if it is low.
6. Put the radiator cap back on, and tighten it
fully.
7. Pour coolant into the reserve tank until it
reaches the MAX mark. Put the cap back
on the reserve tank.

any. Clean up any spills immediately; they can
damage components in the engine compartment.

WARNING
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 TiresChecking TiresTo 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 specification’s 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 and before long trips, use a gauge to measure the pressure in
all tires, including the spare. Even tires in good condition can lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf/cm
2) per month.
■Inspection guidelines
Every time you check inflation, also examine 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 side 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 dealer check the wheel alignment.
• Excessive tread wear.2 Wear Indicators P. 426
•Cracks or other damage around valve stem.
1Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been par ked for at least three
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, 0.3–0.4 kgf/cm
2) higher than if
checked when cold.
Have a dealer check the tires if you feel a consistent
vibration while driving. New tires and any that have
been removed and reinstalled should be properly
balanced.
3
WARNING
Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seri ously hurt or killed.
Follow all instruc tions in this owner’s
manual regarding tire inflation and
maintenance.

uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
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 controlle d 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 heat when tested under controlled conditions
on a specified indo or laboratory test wheel. Sustained high
temperature can cause the material of the tire to degenerate and
reduce tire life, and excessive temperature 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 TractionWarning: 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.1TemperatureWarning: The temperature grade for
this tire is established 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.
