Starting and Stopping the Engine –
Frequently Asked Questions
Why is the engine idle speed high when I
am starting the engine?
The speed at which the engine idles
immediately after starting is optimized
to minimize vehicle emissions and
maximize cabin comfort and fuel
economy.
Why does the engine not crank? You can only attempt to start the engine
for a limited amount of time before the
starting system temporarily disables. If
you exceed the starting time limit, a
message may appear and you cannot
attempt to start the engine for at least
15 minutes. Why do I experience different driving
characteristics?
If you disconnect the battery, your
vehicle may exhibit some unusual
driving characteristics for approximately
5 mi (8 km) after you reconnect it. This
is because the engine management
system must realign itself with the
engine. You can disregard any unusual
driving characteristics during this period.

FUEL AND REFUELING
PRECAUTIONS
WARNING: Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire. WARNING:
The fuel system may be
under pressure. If you hear a hissing sound
near the fuel filler inlet, do not refuel until
the sound stops. Otherwise, fuel may spray
out, which could cause serious personal
injury. WARNING:
Fuels can cause serious
injury or death if misused or mishandled. WARNING:
Fuel may contain
benzene, which is a cancer-causing agent. WARNING:
When refueling always
shut the engine off and never allow sparks
or open flames near the fuel tank filler
valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes. WARNING:
Read and follow all the
instructions on the pump island.
Follow these guidelines when refueling:
• Extinguish all smoking materials and any
open flames before refueling your
vehicle.
• Switch the engine off before refueling.
• Automotive fuels can be harmful or fatal
if swallowed. Fuel is highly toxic and if
swallowed can cause death or permanent
injury. If fuel is swallowed immediately
call a physician, even if no symptoms are
immediately apparent. The toxic effects
of fuel may not be apparent for hours. •
Avoid inhaling fuel vapors. Inhaling fuel
vapor can lead to eye and respiratory
tract irritation. In severe cases, excessive
or prolonged breathing of fuel vapor can
cause serious illness and permanent
injury.
• Avoid getting fuel in your eyes. If you
splash fuel in your eyes, immediately
remove contact lenses, if worn, flush with
water for 15 minutes and seek medical
attention. Failure to seek proper medical
attention could lead to permanent injury.
• Fuels can be harmful if absorbed through
the skin. If you splash fuel on your skin,
clothing or both, promptly remove
contaminated clothing and thoroughly
wash your skin with soap and water.
Repeated or prolonged skin contact
causes skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram for
the treatment of alcoholism. Breathing
fuel vapors could cause an adverse
reaction, serious personal injury or
sickness. Immediately call a physician if
you experience any adverse reactions.

FUEL QUALITY
Selecting the Correct Fuel
Your vehicle operates on regular unleaded
gasoline with a minimum pump (R+M)/2
octane rating of 87.
Some fuel stations, particularly those in high
altitude areas, offer fuels posted as regular
unleaded gasoline with an octane rating
below 87. The use of these fuels could result
in engine damage that will not be covered
by the vehicle Warranty. For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well as
other conditions, for example when towing
a trailer. See Towing a Trailer (page 299).
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.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal vehicle
and engine performance.
For additional information, visit
www . toptiergas. com .
Note: Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty. 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, which is a manganese-based fuel
additive, will impair engine performance and
affect the emission control system.

RUNNING OUT OF FUEL
Filling a Portable Fuel Container
WARNING: Flow of fuel through a
fuel pump nozzle can produce static
electricity. This can cause a fire if you are
filling an ungrounded fuel container.
Use the following guidelines to avoid
electrostatic charge build-up, which can
produce a spark, when filling an ungrounded
fuel container:
• Only use an approved fuel container to
transfer fuel to your vehicle. Place the
container on the ground when filling it.
• Do not fill a fuel container when it is
inside your vehicle (including the cargo
area). •
Keep the fuel pump nozzle in contact
with the fuel container when filling it.
• Do not use a device that holds the fuel
pump nozzle lever in the fill position.
Adding Fuel From a Portable Fuel
Container WARNING: Do not insert the nozzle
of a fuel container or an aftermarket funnel
into the fuel filler neck. This may damage
the fuel system filler neck or its seal and
cause fuel to run onto the ground. WARNING:
Do not pry open the fuel
tank filler valve. This could damage the fuel
system. Failure to follow this instruction
could result in fire, personal injury or death. WARNING: Do not dispose of fuel in
the household refuse or the public sewage
system. Use an authorized waste disposal
facility. When refueling the vehicle fuel tank from a
fuel container, use the fuel filler funnel
included with your vehicle.
See Locating
the Fuel Filler Funnel (page 198).
Note: Do not use aftermarket funnels as they
may not work with the capless fuel system
and can damage it.
When refueling the vehicle fuel tank from a
fuel container, do the following:
1. Fully open the fuel filler door. 199
