FUEL QUALITY
Choosing the Right Fuel
E161513
Use only regular unleaded gasoline with a
minimum pump (R+M)/2 octane rating of
87. Some fuel stations offer fuels posted
as regular unleaded gasoline with an
octane rating below 87, particularly in high
altitude areas. Fuels with octane levels
below 87 are not recommended.
Do not use any fuel other than those
recommended because they could lead to
engine damage that may not be covered
by the vehicle Warranty.
Note: Use of any fuel other than those
recommended can impair the emission
control system and cause a loss of vehicle
performance.
Do not use:
• Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuel containing more than 15% ethanol
or E85 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel (using leaded fuel is
prohibited by law).
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.
Do not be concerned if the engine
sometimes knocks lightly.
However, if it knocks heavily under most
driving conditions while you are using fuel
with the recommended octane rating,
contact an authorized dealer to prevent
any engine damage.
Fuel Freshness Mode (If Equipped)
This helps keep the fuel system functional
and the fuel fresh.
If you mainly use your vehicle in electric
power mode without refueling, the gasoline
in the fuel tank may become stale due to
aging. Stale gasoline can damage the
engine and fuel system.
Your vehicle automatically switches to fuel
freshness mode if you do not refuel your
vehicle with fresh fuel within an 18-month
period. 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
use fuel until approximately 1.2 gal (4.5 L)
of fuel remains in the fuel tank.
During fuel freshness mode:
• The information display will indicate
fuel freshness mode is active.
• The vehicle will only run in hybrid mode.
EV Now mode will not be available.
• Most of the plug-in power will be
stored until fuel freshness mode is
completed.
