Heated Exterior Mirror (If Equipped)
Note:Do not remove ice from the mirrors with a scraper or attempt to
readjust the mirror glass that has frozen in place. These actions could
cause damage to the glass and mirrors.
Note:Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum-based cleaning products.
Both mirrors heat to remove ice, mist and fog when you turn the rear
window defroster on.
CABIN AIR FILTER
Note:A cabin air filter must be installed at all times to prevent foreign
objects from entering the system. Running the system without a filter in
place could result in degradation or damage to the system.
Your vehicle is equipped with a cabin air filter, which is located just in
front of the windshield under the cowl grille on the passenger side of the
vehicle.
The particulate air filtration system is designed to reduce the
concentration of airborne particles, such as dust, spores and pollen, in
the air being supplied to the interior of the vehicle. The particulate
filtration system gives the following benefits to customers:
•Improves the customer’s driving comfort by reducing particle
concentration.
•Improves the interior compartment cleanliness.
•Protects the climate control components from particle deposits.
For more information regarding the interval at which you should replace
the cabin air filter, see theScheduled Maintenancechapter.
For additional cabin air filter information, or to replace the filter, see an
authorized dealer.

SAFETY 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:Automotive fuels can cause serious injury or death if
misused or mishandled.
WARNING:The flow of fuel through a fuel pump nozzle can
produce static electricity, which can cause a fire if fuel is pumped
into an ungrounded fuel container.
WARNING:Fuel ethanol and gasoline 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 filler neck. Never smoke
while refueling. Fuel vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling excess fumes.
Observe the following guidelines when handling automotive fuel:
•Extinguish all smoking materials and any open flames before refueling
your vehicle.
•Always turn off the vehicle before refueling.
•Automotive fuels can be harmful or fatal if swallowed. Fuel, such
as gasoline, is highly toxic and if swallowed can cause death or
permanent injury. If fuel is swallowed, call a physician immediately,
even if no symptoms are immediately apparent. The toxic effects of
fuel may not be visible for hours.
•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
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 liquid in your eyes. If fuel is splashed in the eyes,
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 also be harmful if absorbed through the skin. If fuel is
splashed on the skin or clothing, 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,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
FUEL QUALITY
Note:Use of any fuel other than those recommended may cause
powertrain damage and a loss of vehicle performance; repairs may not be
covered under warranty.
Choosing the Right Fuel
Use only UNLEADED fuel or UNLEADED fuel blended with a maximum
of 15% ethanol. Do not use fuel ethanol (E85), diesel fuel, fuel methanol,
leaded fuel or any other fuel because it could damage or impair the
emission control system.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives. The use of leaded fuel
is prohibited by law.

Octane Recommendations
•3.7L V6 engine
Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is
recommended. Some stations offer fuels posted as Regular with an
octane rating below 87, particularly in high altitude areas. Do not use
fuels with octane
posted on pump below 87.
•5.0L V8 engine
Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is
recommended. Some stations offer fuels posted as “Regular” with an
octane rating below 87, particularly in high altitude areas. Fuels with
octane levels below 87 are not recommended. Do not use fuels with
octane posted on pump below 87.
Premium fuel will provide improved performance and is recommended
for severe duty usage, such as trailer tow.
•For Shelby GT500 octane requirements, see the Shelby GT500
Supplement.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily while you are using fuel with the recommended octane
rating, see your 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, crank time will be 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, seeWarning Lamps and
Indicatorsin theInstrument Clusterchapter.

Refilling with a Portable Fuel Container
WARNING:Do not insert the nozzle of a portable fuel container
or aftermarket funnel 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.
WARNING: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 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.
1. Locate the white plastic funnel in the spare tire
compartment.
2. Slowly insert the funnel into the capless fuel
system.
3. Fill the vehicle with fuel from the portable fuel
container.
4. When done, clean the funnel or properly dispose of it. Extra funnels
can be purchased from your authorized dealer if you choose to dispose
of the funnel.

REFUELING
WARNING:Fuel vapor burns violently and a fuel fire can cause
severe injuries. To help avoid injuries to you and others:
•Read and follow all the instructions on the pump island.
•Turn off your engine when you are refueling.
•Do not smoke if you are near fuel or refueling your vehicle.
•Keep sparks, flames and smoking materials away from fuel.
•Stay outside your vehicle and do not leave the fuel pump unattended
when refueling your vehicle - this is against the law in some places.
•Keep children away from the fuel pump; never let children pump
fuel.
•Do not use personal electronic devices while refueling.
Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
•Place approved fuel container on the ground.
•DO NOT fill a fuel container while it is in the vehicle (including the
cargo area).
•Keep the fuel pump nozzle in contact with the fuel container while
filling.
•DO NOT use a device that would hold the fuel pump handle in the fill
position.
Easy Fuel® No Cap Fuel System
WARNING:The fuel system may be under pressure. If you hear
a hissing sound near the fuel filler door, do not refuel until the
sound stops. Otherwise, fuel may spray out, which could cause serious
personal injury.
When fueling your vehicle:
1. Turn the engine off.
2. Open the fuel filler door by pressing the center of the door about one
inch from the door’s rear edge.
3. Slowly insert the fuel filler nozzle fully into the fuel system, and leave
the nozzle fully inserted until you are done pumping.

4. After you are done pumping fuel, slowly remove the fuel filler
nozzle—allow about 10 seconds after pumping fuel before removing the
fuel filler nozzle. This allows residual fuel to drain back into the fuel tank
and not spill onto the vehicle.
Note:A fuel spillage concern may occur if overfilling the fuel tank. Do
not overfill the tank to the point that the fuel is able to bypass the fuel
filler nozzle. The overfilled fuel may run down the drain located within
the fuel filler housing and to the ground.
If the fuel fill inlet was not properly closed, a Check Fuel Fill Inlet
message may appear on the information display.
At the next opportunity, do the following:
1. Safely pull off the road.
2. Turn off the engine.
3. Open the fuel filler door and remove any visible debris from the fuel
fill opening.
4. Insert either the fuel fill nozzle or the fuel fill funnel provided with the
vehicle several times to dislodge any debris and allow the inlet to close
properly.
If this action corrects the problem, the message may not reset immediately.
It may take several driving cycles for the message to turn off. A driving
cycle consists of an engine start-up (after four or more hours with the
engine off) followed by city or highway driving. Continuing to drive with
the message on may cause the service engine soon lamp to turn on as well.
FUEL CONSUMPTION
Filling the Tank
The advertised capacity is the indicated capacity and the empty reserve
combined. Indicated capacity is the difference in the amount of fuel in a
full tank and a tank when the fuel gauge indicates empty. Empty reserve
is the amount of fuel in the tank after the fuel gauge indicates empty.
Note:The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your vehicle
after the fuel gauge indicates empty, you might not be able to refuel the
full amount of the advertised capacity of the fuel tank due to the empty
reserve still present in the tank.

For consistent results when filling the fuel tank:
•Turn the ignition off before fueling; an inaccurate reading results if the
engine is left running.
•Use the same fill rate (low–medium–high) each time the tank is filled.
•Allow no more than two automatic click–offs when filling.
Results are most accurate when the filling method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the first 1000 miles
(1600 kilometers) of driving (this is your engine’s break-in period); a
more accurate measurement is obtained after 2000 miles–3000 miles
(3200 kilometers–4800 kilometers). Also, fuel expense, frequency of
fill-ups or fuel gauge readings are not accurate ways to measure fuel
economy.
1. Fill the fuel tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Calculate fuel economy as follows:
Standard: Divide miles traveled by gallons used.
Metric: Multiply liters used by 100, then divide by kilometers traveled.
Keep a record for at least one month and record the type of driving (city
or highway). This provides an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter show how temperature impacts fuel economy.
In general, lower temperatures mean lower fuel economy.
