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 accord ance with the messages displayed on the
multi-information display.
• Use engine oil with the viscosity recommended.
2 Recommended Engine Oil P. 504
•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

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 maintena nce booklet for detailed maintenance and
inspection information.
■Daily inspections
Perform inspections before long distance tri ps, when washing the vehicle, or when
refueling.
■Periodic inspections
• Check the brake fluid level monthly.
2 Brake Fluid P. 512
•Check the tire pressure monthly. Examin e the tread for wear and foreign objects.
2Checking and Maintaining Tires P. 520
•Check the operation of the exterior lights monthly.
2 Replacing Light Bulbs P. 514
•Check the condition of the wiper bl ades at least every six months.
2Checking and Maintaining Wiper Blades P. 517
■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 maintenance services should
be performed in accordan ce with the intervals
indicated by the mult i-information display.
2 Maintenance Service Items P. 498
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. 595
If you want to perform ma intenance yourself, make
sure that you have the necessary tools and skills first.
After performing ma intenance, update the records in
the separate maintenance booklet.

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
*1: If a message Maintenance Due Now does not appear more than 12 months after the display is
reset, change the engine oil every year.
# : See information on maintenance and emissions warranty.
CODEMaintenance Main Items
A •Replace engine oil*1
B•Replace engine oil*1 and oil filter
• Inspect front and rear brakes
• Check expiration date for temporary tire repair kit
bottle (if equipped)
• Inspect tie rod ends, steering gearbox, and boots
• Inspect suspension components
• Inspect driveshaft boots
• Inspect brake hoses and li nes (Including ABS/VSA®)
• Inspect all fluid levels and condition of fluids
• Inspect exhaust system
#
•Inspect fuel lines and connections#*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
*3: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and
from diesel-powered vehicles, replace the dust and pollen filter every 15,000 miles (24,000 km).
*4: Driving in mountainous areas at very low vehicle speeds results in higher transmission temperature. This requires transmission fluid changes more frequently than recommended by the Maintenance
Minder. If you regularly drive your vehicle under this condition, have the transmission fluid changed at
30,000 miles (48,000 km), then every 25,000 miles (40,000 km).
*5: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under -20°F, -29°C), replace every 60,000 miles (100,000 km).
*6: Driving in mountainous areas at very low vehicle speeds results in higher level of mechanical (Shear) stress to fluid. This requires Twin Motor Unit fluid changes more frequently than recommended by the
Maintenance Minder. If you regularly drive your vehicle under this condition, have the Twin Motor Unit
fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).
