GENERAL INFORMATION
WARNINGS
Extended idling at high engine speeds
can produce very high temperatures
in the engine and exhaust system, creating
the risk of fire or other damage. Do not park, idle or drive your vehicle
on dry grass or other dry ground cover.
The emission system heats up the engine
compartment and exhaust system, creating
the risk of fire. Do not start the engine in a closed
garage or in other enclosed areas.
Exhaust fumes can be toxic. Always open
the garage door before you start the engine. If you smell exhaust fumes inside your
vehicle, have your vehicle checked by
an authorized dealer immediately. Do not
drive your vehicle if you smell exhaust fumes. If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately 5 miles (8
kilometers) 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.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start the engine, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the engine.
KEYLESS STARTING
Note:
The system may not function if the
passive key is close to metal objects or
electronic devices, for example keys or a
cell phone.
Note: A valid passive key must be located
inside your vehicle to switch the ignition on
and start your vehicle. Note:
A light on the button illuminates when
the ignition is on and when your vehicle
starts.

4.
Operate the fuel pump nozzle within the
area shown. 5. Slightly raise the fuel pump nozzle and
then slowly remove it.
6. Fully close the fuel tank filler door. Note:
Do not attempt to start the engine if
you have filled the fuel tank with incorrect
fuel. Incorrect fuel use can cause damage
not covered by the vehicle Warranty. Have
your vehicle checked immediately.
System Warnings (If Equipped)
If the fuel filler inlet does not fully close a
warning message appears in the information
display.
1. Stop your vehicle as soon as safely possible and shift the transmission into
park (P) or neutral (N).
2. Apply the parking brake and switch the ignition off.
3. Fully open the fuel tank filler door until it
engages.
4. Check the fuel filler inlet and the area around it for any items or debris that may
be obstructing its movement. 5.
Insert a fuel pump nozzle or the fuel filler
funnel provided with your vehicle in to
the fuel tank filler pipe opening. This
action should dislodge any debris that
may be preventing the fuel filler inlet from
fully closing.
Note: If this action corrects the problem the
message may not reset immediately. If the
message remains and the service engine
soon warning lamp appears in the
information display, have your vehicle
checked as soon as possible.
FUEL CONSUMPTION
Empty reserve is the amount of fuel
remaining in the tank after the fuel gauge
indicates empty. The amount of usable fuel
in the empty reserve varies and should not
be relied upon to increase driving range.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If a
metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Alloy Wheels
(page 292). See
Warning Lamps and
Indicators (page 98).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Move
the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Brake Assist
Brake assist detects when you brake rapidly
by measuring the rate at which you press the
brake pedal. It provides maximum braking
efficiency as long as you press the pedal,
and can reduce stopping distances in critical
situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily illuminates
when you turn the ignition on. If
the light does not illuminate during
start up, remains on or flashes, the system
may be disabled. Have the system checked
by an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still
effective. If the brake warning lamp remains
illuminated after you release the
parking brake, have the system
checked by an authorized dealer.
HINTS ON DRIVING WITH ANTI-
LOCK BRAKES
Note: When the system is operating, the
brake pedal may pulse and may travel
further. Maintain pressure on the brake
pedal. You may also hear a noise from the
system. This is normal.

TRAILER SWAY CONTROL WARNING
Turning off trailer sway control
increases the risk of loss of vehicle
control, serious injury or death. Ford does
not recommend disabling this feature except
in situations where speed reduction may be
detrimental (such as hill climbing), the driver
has significant trailer towing experience, and
can control trailer sway and maintain safe
operation. Note:
This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying. Note:
In some cases, if vehicle speed is too
high, the system may activate multiple times,
gradually reducing vehicle speed.
This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message TRAILER SWAY REDUCE SPEED
appears in the information display. The first
thing to do is slow your vehicle down, then
pull safely to the side of the road and check
for proper tongue load and trailer load
distribution.
See Load Carrying (page 209).
RECOMMENDED TOWING
WEIGHTS
Note: Do not exceed the trailer weight
for your vehicle configuration listed in
the chart below. Note:
Make sure to take into
consideration trailer frontal area. Do not
exceed 36.5 feet² (3.39 meters²) if your
vehicle is equipped with the standard
towing package, or 60 feet² (5.57
meters²) if your vehicle is equipped with
the optional heavy duty package.
Note: Exceeding this limitation may
significantly reduce the performance of
your towing vehicle. Selecting a trailer
with a low aerodynamic drag and
rounded front design helps optimize
performance and fuel economy.
Note: For high altitude operation,
reduce the gross combined weight by
2% per 1000 feet (300 meters) starting
at the 1000 foot (300 meter) elevation
point.

There are also some things you may want to
avoid doing because they reduce your fuel
economy:
•
Avoid sudden or hard accelerations.
• Avoid revving the engine before turning
off the car.
• Avoid long idle periods.
• Do not warm up your vehicle on cold
mornings.
• Reduce the use of air conditioning and
heat.
• Avoid using speed control in hilly terrain.
• Do not rest your foot on the brake pedal
while driving.
• Avoid carrying unnecessary weight.
• Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski
racks).
• Avoid driving with the wheels out of
alignment. DRIVING THROUGH WATER WARNING
Do not drive through flowing or deep
water as you may lose control of your
vehicle. Note:
Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water, check
the depth. Never drive through water that is
higher than the bottom of the wheel hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that the
steering power assist works.
FLOOR MATS WARNINGS
Always use floor mats that are
designed to fit the foot well of your
vehicle. Only use floor mats that leave the
pedal area unobstructed. Only use floor mats
that are firmly secured to retention posts so
that they cannot slip out of position and
interfere with the pedals or impair safe
operation of your vehicle in other ways.

ENGINE COOLANT CHECK WARNINGS
Do not add engine coolant when the
engine is hot. Steam and scalding
liquids released from a hot cooling system
can burn you badly. Also, spilling coolant on
hot engine parts can burn you. Do not put engine coolant in the
windshield washer fluid container. If
sprayed on the windshield, engine coolant
could make it difficult to see through the
windshield. WARNINGS
To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure relief cap.
The cooling system is under pressure. Steam
and hot liquid can come out forcefully when
you loosen the cap slightly. Do not add coolant further than the
MAX mark.
When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information.
See Scheduled Maintenance
(page 456).
Note: Make sure that the coolant level is
between the
MIN and MAX marks on the
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark. Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.
Adding Coolant WARNING
Never remove the coolant reservoir
cap while the engine is running or hot.
Note:
Automotive fluids are not
interchangeable. Take care not to put
engine coolant in the windshield washer fluid
reservoir or windshield washer fluid in the
engine coolant reservoir.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
