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
driver information interface.
• Use the recommended viscosity engine oil.
• 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 designed 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 hard or sudden
acceleration.
• Always replace the engine oil and en gine oil filter according to the
Maintenance Minder
TM.
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 filt er at the scheduled distance or interval,
deteriorated engine oil may cause failure su ch as sticking and abnormal noise of the
turbine bearing.
1 Turbo Engine Vehicle
The scheduled maintenance intervals for replacing
the engine oil and filt er is indicated on the
Maintenance Minder
TM. Follow the information of
when to replace them.
2 Maintenance Minder
TM P. 379
2 Recommended Engine Oil P. 390
The temperature gauge needle 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 needle goes down
after you idle or drive the vehicle for about one
minute.

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 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 flam mable objects under the hood and hatch.
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 pr otective 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.
• 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 power system is turned off.
• Be aware that hot parts can burn you.
u Make sure to let the power system, including the engine and exhaust system,
cool thoroughly before touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not activate the power system unle ss instructed, and keep your hands and
limbs away from moving parts. When the power system is on, the engine can
automatically start, or the radiator fa n may start operating without the engine
running.

from diesel-powered vehicles, replace the dust and pollen filters every 15,000 miles (24,000 km) or
every year.
*4: Driving in mountainous areas at very low vehicle speeds results in higher transmission temperature. This requires transmission fluid and clutch fluid changes more frequently than recommended by the
Maintenance Minder. If you regularly drive your vehicle under this condition, have the transmission
fluid and clutch fluid changed every 20,000 miles (32,000 km).
*5: 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 these conditions, have the Twin Motor
Unit fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).
