•
Fuels can also be harmful if absorbed
through the skin. If fuel is splashed on
the skin, clothing or both, promptly
remove contaminated clothing and wash
skin thoroughly with soap and water.
Repeated or prolonged skin contact with
fuel liquid or vapor causes skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram for
the treatment of alcoholism. Breathing
gasoline vapors could cause an adverse
reaction, serious personal injury or
sickness. If fuel is splashed on the skin,
wash the affected areas immediately with
plenty of soap and water. Consult a
physician immediately if you experience
any adverse reactions. FUEL QUALITY
Choosing the Right Fuel We recommend regular unleaded gasoline
with a minimum 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. To provide improved performance,
we recommend premium fuel for severe duty
usage such as trailer tow.
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 the
engine knocks heavily while using fuel with
the recommended octane rating, contact an
authorized dealer to prevent any engine
damage.
RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
powertrain components.
If you have run out of fuel:
•
You may need to cycle the ignition from
off to on several times after refueling to
allow the fuel system to pump the fuel
from the tank to the engine. On
restarting, cranking time will take a few
seconds longer than normal. With keyless
ignition, just start the engine. Crank time
will be longer than usual.
• Normally, adding 1 gallon (3.8 liters) of
fuel is enough to restart the engine. If the
vehicle is out of fuel and on a steep
grade, more than 1 gallon (3.8 liters) may
be required.
• The service engine soon indicator may
come on. For more information on the
service engine soon indicator, See
Warning Lamps and Indicators (page
103). Refilling With a Portable Fuel Container WARNINGS
Do not insert the nozzle of portable
fuel containers or aftermarket funnels
into the capless fuel system. This could
damage the fuel system and its seal, and
may cause fuel to run onto the ground
instead of filling the tank, which could result
in serious personal injury. Do not try to pry open or push open
the capless fuel system with foreign
objects. This could damage the fuel system
and its seal and cause injury to you or others. Note:
Do not use aftermarket funnels; they
will not work with the capless fuel system
and can damage it. The included fuel funnel
has been specially designed to work safely
with your vehicle.
When filling the vehicle ’s fuel tank from a
portable fuel container, use the funnel
included with the vehicle.
