Fuel Economy and CO2 Emissions
Improving Fuel Economy and Reducing CO2
Emissions
Achieving fuel economy and reducing CO2 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
information display
*/driver information interface*.
• Use the recommended viscosity engine oil, displaying the API Certification Seal.
• Maintain the specified tire pressure.
• Do not load the vehicl e with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle's underside
adds weight and increases wind resistance.
■Maintenance and Fuel Economy
1Improving Fuel Economy and Reducing CO2 Emissions
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test. For more

Driving
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 sta rting, 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 1,2 92°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 caus e failure such as sticking and abnormal
noise of the turbine bearing.1 Turbo Engine Vehicle*
The scheduled maintenance intervals for replacing
the filter is indicated on the driver information
interface. Follow the information of when to replace
them. 2 Maintenance Minder
TM P. 513
The temperature gauge pointer is at the mark
when you restart the engi ne 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 vehi cle 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.)
■Daily inspections
Perform inspections before long distance trips, when washing the vehicle, or when
refueling.
■Periodic inspections
• Check the brake/clutch* fluid level monthly.
2 Brake/Clutch* Fluid P. 536
•Check the tire pressure monthly. Examin e the tread for wear and foreign objects.
2Checking and Maintaining Tires P. 550
•Check the operation of the exterior lights monthly.
2 Replacing Light Bulbs P. 538
•Check the condition of the wiper bl ades at least every six months.
2Checking and Maintaining Wiper Blades P. 547
■Types of Inspection and Maintenance
1Inspection 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 fede ral regulations, failure to
perform maintenance on the maintenance main
items marked with # will not void your emissions
warranties. However, all ma intenance services should
be performed in accordan ce with the intervals
indicated by the information display
*/driver
information interface*.
2 Maintenance Service Items P. 515, 520
If you want to perform complex maintenance tasks
that require more skills a nd tools, you can purchase a
subscription to the Service Express website at
www.techinfo.honda.com .
2 Authorized Manuals P. 629
If you want to perform ma intenance yourself, make
sure that you have the necessary tools and skills first.

Safety When Performing Maintenance
Some of the most important safe ty precautions are given here.
However, we cannot warn you of every conceivable 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 explos ion, 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 co mmercially available degreaser or parts cleaner, not
gasoline.
• Wear eye protection and prot ective 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 th ere is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on le vel 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 instruct ed, and keep your hands and limbs away
from moving parts.
