the On Board Diagnostics system (OBD) has
detected a malfunction of the vehicle
emissions control system. Refer to On Board
Diagnostics (OBD) in the Fuel and Refueling
chapter for more information about having
your vehicle serviced. See Emission Control
System (page 168).
If the light is blinking, engine misfire is
occurring which could damage your catalytic
converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and
have your vehicle serviced immediately. WARNING
Under engine misfire conditions,
excessive exhaust temperatures could
damage the catalytic converter, the fuel
system, interior floor coverings or other
vehicle components, possibly causing a fire.
Have an authorized dealer service your
vehicle immediately. The service engine soon indicator light
illuminates when you first switch on the

STARTING A GASOLINE ENGINE
When you start the engine, the idle speed
increases. This helps to warm up the engine.
If the engine idle speed does not slow down
automatically, have your vehicle checked by
an authorized dealer. Note:
You can crank the engine for a total
of 60 seconds without the engine starting
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each time,
without the engine starting, you reached the
60-second time limit. A message appears
in the information display alerting you that
you exceeded the cranking time. You
cannot attempt to start the engine for at
least 15 minutes. After 15 minutes, you are
limited to a 15-second engine cranking time.
You need to wait 60 minutes before you can
crank the engine for 60 seconds again.
Before starting your vehicle, check the
following:
• Make sure all occupants have fastened
their safety belts.
• Make sure the headlamps and electrical
accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park (P).
Note: Do not touch the accelerator pedal. Note:
You must have your intelligent access
key in your vehicle to shift the transmission
out of park (P).
1. Fully depress the brake pedal.
2. Press the push button ignition switch.
The system does not function if:
• The passive key frequencies are jammed.

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 and an
authorized dealer should check them. If the
vehicle has continuous vibration or shudder
in the steering wheel while braking, an
authorized dealer should check your vehicle.
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 101).
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. Switch
the engine off, move the transmission to park
(P) and apply the parking brake. Inspect the
accelerator pedal and the area around it for
any items or debris that may be obstructing
its movement. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at which
you press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal. Emergency brake assist 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 switch the ignition on. If
the light does not illuminate during
start up, remains on or flashes, the anti-lock
braking 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
illuminates with the parking brake
released, have your brake system
serviced immediately.
HINTS ON DRIVING WITH ANTI-
LOCK BRAKES
Note: When the system is operating, the
brake pedal will 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 212).
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.

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.
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of the engine coolant
at the intervals listed in the scheduled
maintenance information.
See Scheduled
Maintenance (page 353).
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.
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Note:
For best results, coolant concentration
should be tested with a refractometer such
as Robinair® Coolant and Battery
Refractometer 75240. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant,
antifreeze or windshield washer fluid outside
of its specified function and vehicle location.
Adding Engine Coolant
Note: Do not use stop leak pellets, cooling
system sealants or additives as they can
cause damage to the engine cooling or
heating systems. Your warranty may not
cover these damages. Note:
During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.
Do not mix different colors or types of
coolant in your vehicle. Mixing of engine
coolants may harm your engine ’s cooling
system. Use prediluted engine coolant
meeting the correct specification.
See
Capacities and Specifications (page 328).
The use of an incorrect coolant may harm
the engine or cooling system components
and may not be covered by the vehicle
Warranty.
In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the cooling system with
Motorcraft Premium Cooling System
Flush.

What You Should Know About Fail-Safe
Cooling
If you deplete the engine coolant supply,
fail-safe cooling allows you to temporarily
drive your vehicle before you incur
incremental component damage. The
fail-safe distance depends on ambient
temperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine
coolant temperature gauge will move to the
red (hot) area and:
the coolant temperature warning
light will illuminate
the service engine soon indicator
will illuminate.
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 will still
operate. However:
•
The engine power will be limited.
• This will disable the air conditioning
system.
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 your engine. Take your vehicle to an
authorized dealer as soon as possible to
minimize engine damage.
When Fail-Safe Mode Is Activated WARNINGS
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 WARNINGS
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. Never remove the coolant reservoir
cap while the engine is running or hot.
You have limited engine power when in the
fail-safe mode, so drive your vehicle with
caution. Your vehicle will not maintain
high-speed operation and the engine will
operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch off the engine.
2. Tow your vehicle to an authorized dealer.
3. If this is not possible, wait a short period
for the engine to cool.
4. Check the coolant level and add if low.
