5. Place the end of the filler nozzle on the

lower part of filler opening, then insert it
slowly and fully.

u

Make sure that the end of the filler
nozzle goes down along with the filler
pipe.

u

Keep the filler nozzle level.

u

When the tank is full, the filler nozzle will
click off automatically.

u

After filling, wait about five seconds
before removing the filler nozzle.

6. Shut the fuel fill door by hand.

1

How to Refuel

If the 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 after the filler nozzle has
automatically stopped. Additional fuel can exceed
the full tank capacity.

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 you have to refuel your vehicle from a portable
container, use the funnel provided with your vehicle.

Achieving fuel economy and reducing CO

emissions is dependent on several

factors, including driving conditions, load weight, idling time, driving habits, and
vehicle condition. Depending on these and other factors, you may not achieve the
rated fuel economy of this vehicle.

You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accordance with the messages displayed on the
multi-information display.
• Use the recommended viscosity engine oil.

2 Recommended Engine Oil P. 535

• Maintain the specified tire pressure.
• Do not load the vehicle with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle’s underside

adds weight and increases wind resistance.

Turbo Engine Vehicle

Handling Precautions

The turbocharger is a high-precision device to obtain greater horsepower by
delivering a large volume of compressed air into the engine using a turbine driven by
the engine’s exhaust gas pressure.

• When the engine is cold just after starting, avoid revving the engine or sudden

acceleration.

• Always replace the engine oil and engine oil filter according to the Maintenance

Minder. The turbine rotates at very high speeds over 100,000 rpm and its
temperature reaches over 1,292°F (700°C). It is lubricated and cooled by engine
oil. If you fail to replace the engine oil and filter at the scheduled distance or
interval, deteriorated engine oil may cause failure such as sticking and abnormal
noise of the turbine bearing.

Turbo Engine Vehicle

The scheduled maintenance intervals for replacing
the filter is indicated on the multi-information
display. Follow the information of when to replace
them.

The temperature gauge pointer is at the

mark

when you restart the engine after driving under high
load conditions such as at high speed or in hilly
terrain. This is normal. The gauge goes down after
you idle or drive the vehicle for about one minute.

Before Performing Maintenance

Inspection and Maintenance

For your safety, perform all listed inspections and maintenance to keep your vehicle
in good condition. If you become aware of any abnormality (noise, smell, insufficient
brake fluid, oil residue on the ground, etc.), have your vehicle inspected by a dealer.
(Note, however, that service at a dealer is not mandatory to keep your warranties in
effect.) Refer to the separate maintenance booklet for detailed maintenance and
inspection information.

■

Daily inspections

Perform inspections before long distance trips, when washing the vehicle, or when
refueling.

■

Periodic inspections

• Check the brake fluid level monthly.

2 Checking the Brake Fluid P. 543

• Check the tire pressure monthly. Examine the tread for wear and foreign objects.

2 Checking and Maintaining Tires P. 554

• Check the operation of the exterior lights monthly.

2 Replacing Light Bulbs P. 545

• Check the condition of the wiper blades at least every six months.

2 Checking and Maintaining Wiper Blades P. 549

■

Types of Inspection and Maintenance

1

Inspection and Maintenance

Maintenance, replacement, or repair of
emissions control devices and systems may be
done by any automotive repair establishment or
individuals using parts that are “certified” to
EPA standards.

According to state and federal regulations, failure to
perform maintenance on the maintenance main
items marked with # will not void your emissions
warranties. However, all maintenance services should
be performed in accordance with the intervals
indicated by the multi-information display.

2 Maintenance Service Items P. 529

If you want to perform complex maintenance tasks
that require more skills and tools, you can purchase a
subscription to the Service Express website at
www.techinfo.honda.com.

2 Authorized Manuals P. 638

If you want to perform maintenance yourself, make
sure that you have the necessary tools and skills first.
After performing maintenance, update the records in
the separate maintenance booklet.

Safety When Performing Maintenance

Some of the most important safety precautions 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 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.

u

Do not open the hood while the Auto Idle Stop function is activated.

rest of the way and hold it up.

When closing, lower it to approximately
12 inches (30 cm), then press down firmly with
your hands.

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.

Do not open the hood while the Auto Idle Stop
