9. Fully close the fuel filler door.
Note:
The message may not immediately
reset. If the message continues to appear
and a warning lamp illuminates, have your
vehicle checked as soon as possible.
FUEL CONSUMPTION
Advertised Capacity
The advertised capacity is the maximum
amount of fuel that you can add to the fuel
tank when the fuel gauge indicates empty.
See Capacities and Specifications (page
440).
In addition, the fuel tank contains an empty
reserve. The empty reserve is an unspecified
amount of fuel that remains in the fuel tank
when the fuel gauge indicates empty.
Note: When refueling your vehicle after the
fuel gauge indicates empty, you might not
be able to refuel the full amount of the
advertised capacity due to the empty
reserve still present in the fuel tank. Filling the Fuel Tank
For consistent results when refueling:
•
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 one automatic
shut-off when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Your vehicle calculates fuel economy figures
through the trip computer average fuel
function.
See Information Displays (page
134).
The first 1,000 mi (1,500 km) of driving is the
break-in period of the engine. A more
accurate measurement is obtained after
2,000 mi (3,000 km)
.
1. Completely fill the fuel tank and record the initial odometer reading. 2.
Each time you fill the fuel tank, record the
amount of fuel added.
3. After at least three fill ups, fill the fuel tank and record the current odometer
reading.
4. Subtract your initial odometer reading from the current odometer reading.
To calculate L/100 km (liters per 100
kilometers) fuel consumption, multiply the
liters used by 100, then divide by kilometers
traveled. To calculate MPG (miles per gallon)
fuel consumption, divide miles traveled by
gallons used.
Keep a record for at least one month and
record the type of driving, for example city
or highway. This provides an accurate
estimate of your vehicle ’s fuel economy
under current driving conditions. Keeping
records during summer and winter shows
how temperature impacts fuel economy.

Following a Vehicle
WARNING: When following a vehicle,
your vehicle does not always decelerate
quickly enough to avoid a crash without
driver intervention. Always apply the
brakes when necessary. Failing to do so
may result in a crash, serious injury or
death. WARNING: Adaptive cruise control
only warns of vehicles detected by the
radar sensor. In some cases there may be
no warning or a delayed warning. You
should always apply the brakes when
necessary. Failure to do so may result in a
crash, serious injury or death.
When a vehicle ahead of you enters the
same lane or a slower vehicle is ahead in the
same lane, the vehicle speed adjusts to
maintain a preset gap distance. A vehicle
graphic illuminates in the instrument cluster.
Note: The brakes may emit noise when
applied by the system. Note:
When you are following a vehicle and
you switch on a direction indicator, adaptive
cruise control may provide a small temporary
acceleration to help you pass.
Your vehicle maintains a consistent gap from
the vehicle ahead until:
• The vehicle in front of you accelerates to
a speed above the set speed.
• The vehicle in front of you moves out of
the lane you are in.
• You set a new gap distance.
The system applies the brakes to slow your
vehicle to maintain a safe gap distance from
the vehicle in front. The system only applies
limited braking. You can override the system
by applying the brakes.
If the system determines that its maximum
braking level is not sufficient, an audible
warning sounds, a message appears in the
information display and an indicator flashes
when the system continues to brake. Take
immediate action. Following a Vehicle to a Complete Stop
If your vehicle follows a vehicle to a complete
stop and remains stationary for less than
three seconds, your vehicle accelerates from
a stationary position to follow the vehicle
ahead. If your vehicle follows a vehicle to
a complete stop and remains
stationary for more than three
seconds, press to follow the vehicle ahead.
Or press the accelerator pedal.
Setting the Gap Distance
You can decrease or increase the distance
between your vehicle and the vehicle in front
by pressing the gap control. Press and release to decrease the
gap distance.
Press and release to increase the
gap distance.

Using Driver Alert
Switching the system on and off
You may switch the system on or off through
the information display. See General
Information (page 134). When activated, the
system monitors your alertness level based
upon your driving behavior in relation to the
lane markings, and other factors.
System Warnings
Note: The system does not issue warnings
below approximately
40 mph (64 km/h).
The warning system is in two stages. At first
the system issues a temporary warning that
you need to take a rest. This message will
only appear for a short time. If the system
detects further reduction in driving alertness,
another warning may be issued which will
remain in the information display for a longer
time. Press OK on the steering wheel control
to clear the warning. When active the system
will run automatically in the background and
only issue a warning if required. Resetting the System
You can reset the system by either:
•
Switching the ignition off and on.
• Stopping your vehicle and then opening
and closing the driver’ s door.

Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
440).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear in the
information display. If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
•
Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage. When Fail-Safe Mode Is Activated WARNING: Fail-safe mode is for use
during emergencies only. Operate your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in
a safe location and seek immediate repairs.
When in fail-safe mode, your vehicle will
have limited power, will not be able to
maintain high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.

WARNING: This vehicle may have
more than one battery. Removing the
battery cables from only one battery does
not disconnect your vehicle electrical
system. Make sure you disconnect the
battery cables from all batteries when
disconnecting power. Failure to do so may
cause serious personal injury or property
damage.
Your vehicle is fitted with a Motorcraft
maintenance-free battery which normally
does not require additional water.
When a battery replacement is required, you
must use a recommended replacement
battery that matches the electrical
requirements of the vehicle.
Note: After cleaning or replacing the battery,
make sure you reinstall the battery vent tube,
battery cover or shield.
For longer, trouble-free operation, keep the
top of the battery clean and dry. If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
Because your vehicle
’s engine is
electronically controlled by a computer, some
control conditions are maintained by power
from the battery. When the battery is
disconnected or a new battery is installed,
the engine must relearn its idle and fuel trim
strategy for optimum driveability and
performance. Flexible fuel vehicles (FFV)
must also relearn the ethanol content of the
fuel for optimum driveability and
performance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start your vehicle. 5. Run the engine until it reaches normal
operating temperature. While the engine
is warming up, complete the following:
Reset the clock. Reset the power
windows bounce-back feature.
See
Windows and Mirrors (page 119). Reset
the radio station presets. See Audio
System (page 461).
6. Allow the engine to idle for at least one minute.
7. Drive the vehicle at least 10 mi (16 km) to
completely relearn the idle trim and fuel
trim strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel trim
strategy.
Note: For flexible fuel vehicles, if you are
operating on E85, you may experience poor
starts or an inability to start the engine and
driveability problems until the fuel trim and
ethanol content have been relearned.
