nozzle.
1.Stop your vehicle with the service station
pump on the left side of the vehicle in the
rear.
2. Turn off the engine.
3. Unlock the driver’s door using the master
door lock switch.
u The fuel fill door on the outer side of the
vehicle will unlock.

P. 178
4.Press the area indicated by the arrow to
release the fuel fill door. You will hear a
click.
1How to Refuel
The fuel filler opening is designed to accept only
service station filler nozzles for refueling. Use of
smaller diamet er tubes (e.g., those used to siphon
fuel for other uses) or other non-service station
devices can damage the area in and around the filler
opening.
Use the master door lock switch to unlock the fuel fill
door.
The vehicle doors and fuel fill door automatically
relock if the remote unlock function is used. This can
be deactivated by briefl y opening then closing the
driver’s door.
3WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured
when handling fuel.
• Stop the engine, and keep heat, sparks,
and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.

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
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

Turbo Engine Vehicle
Handling Precautions
The turbocharger is a high-precision device to obtain greater horsepower by
delivering a large volume of compressed air in to 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 1,292°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.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. 611
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.

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 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 degreas er or parts cleaner, not
gasoline.
• Wear eye protection and protective clothi ng 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.
