Note:   Your warranty will not cover any vehicle damage, powertrain damage, loss of vehicle performance or repairs to your vehicle, caused by the use of fuel not recommended.
Choosing the Right Fuel
Use only UNLEADED gasoline or UNLEADED gasoline blended with a maximum of 15% ethanol in your gasoline vehicle. If your vehicle is a Flex Fuel Vehicle (FFV), it will have a yellow bezel placed over the fuel fill inlet.
Do not use:
  • Fuels containing more than 15% ethanol or E-85 fuel.
  • Fuels containing methanol.
  • Fuels containing metallic based additives, including manganese-based compounds.
  • Fuels containing the octane booster additive, methylcyclopentadienyl manganese tricarbonyl (MMT).
  • Prohibited by law, you cannot use leaded fuel.
Note:   Use of any fuel other than the recommended fuel can cause powertrain damage, impair the emission control system or cause loss of vehicle performance. Any damage to your vehicle that is caused by the use of fuel not recommended will not be covered under warranty.
Octane Recommendations
We recommend regular unleaded gasoline with a pump (R+M)/2 octane rating of 87. Some stations offer fuels posted as regular with an octane rating below 87, particularly in high altitude areas. We do not recommend fuels with an octane rating below 87. Premium fuel will provide improved performance and is recommended for severe duty usage such as trailer tow.
Fuel Freshness Mode (Energi Vehicles Only)
This feature helps keep the fuel system functional and the fuel fresh.
If you mainly operate your vehicle in plug-in power mode using electricity from plugging in without refueling, the gasoline in the fuel tank will become stale due to aging over an extended period. Stale gasoline can damage the engine and fuel system.
Your vehicle will automatically operate in fuel freshness mode if you do not refill your vehicle with fresh fuel within an 18-month period. The design of fuel freshness mode protects your vehicle from potential engine and fuel system damage caused by using stale fuel.
Note:   If you do not add new fuel during an 18-month period, fuel freshness mode will consume fuel until you have about 1 gal (3.8 L) in the tank.
During fuel freshness mode:
  • The information display screen will indicate that fuel freshness mode is active.
  • The vehicle will only run in hybrid mode. EV Now will not be available.
  • Most of the plug-in power will be stored until fuel freshness mode is completed.
Note:   EV Now can resume if less than 1 gal (3.8 L) of fuel is left in the tank.
Note:   In most cases, when the fuel level is below one-quarter tank, refueling the vehicle will end fuel freshness mode and then EV Now will become available. Refueling after consuming a full tank in fuel freshness mode will end the mode.
Note:   The recommendation is that you use a fuel stabilizer if you consume less than a full tank of fuel during an 18-month period.
