Opening the Hood

Park the vehicle on a level surface, and set
the parking brake.

Pull the hood release handle under the
driver’s side lower corner of the dashboard.

The hood will pop up slightly.

Push the hood latch lever (located under
the front edge of the hood to the center) to
the side and raise the hood. Once you have
raised the hood slightly, you can release the
lever.

Remove the support rod from the clamp
using the grip. Mount the support rod in
the hood.

When closing, remove the support rod and
stow it in the clamp, then gently lower the
hood. Remove your hand at a height of
approximately 12 inches (30 cm) and let the
hood close.

Opening the Hood

NOTICE

Do not open the hood when the wiper arms are
raised. The hood will strike the wipers, resulting in
possible damage to the hood and/or the wipers.

NOTICE

Do not press the engine cover forcibly. This may
damage the engine cover and component parts.

When closing the hood, check that the hood is
securely latched.

If the hood latch lever moves stiffly, or if you can
open the hood without lifting the lever, the latch
mechanism should be cleaned and lubricated.

WARNING

The hood support rod can become very hot
due to heat from the engine.

To ensure against possible burns, do not

Engine Coolant

Main

Engine Coolant

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 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.

Check the amount of coolant in the reserve
tank.

If the coolant level is below the

MIN

mark, add the specified coolant until it
reaches the

MAX

mark.

Inspect the cooling system for leaks.

Specified coolant: Honda Long Life Antifreeze/Coolant Type 2

■

Engine Coolant

NOTICE

Genuine Honda engine coolant 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 Honda 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-Honda coolant can result
in corrosion, causing the cooling system to
malfunction or fail. Have the cooling system flushed
and refilled with Honda antifreeze/coolant 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.

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 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/cm

) per month.

Checking 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 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

) 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.

WARNING

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.

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.

DOT Tire Quality Grading (U.S. Vehicles)

The tires on your vehicle meet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance according to Department of
Transportation (DOT) standards. The following explains these
gradings.

Quality grades can be found where applicable on the tire sidewall
between tread shoulder and maximum section width.

The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practices and differences in road
characteristics and climate.

Checking and Maintaining Tires

DOT Tire Quality Grading (U.S. Vehicles)

576

Main

tenan

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 heat 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 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.
