When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) or neutral (N)
to aid engine and transmission cooling
and to help air conditioning
performance.
• Switch off the speed control with
heavy loads or in hilly terrain. The
speed control may turn off
automatically when you are towing on
long, steep grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a slope. However, if
you must park on a slope:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in park (P) or manual transmission in a
low gear. 4. Place wheel chocks in front and back
of the trailer wheels. Chocks are not
included with your vehicle.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before
backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Any time the rear axle submerges in water,
replace the rear axle lubricant. Water may
contaminate the rear axle lubricant, which
is not a normal maintenance inspection
item unless there is a possibility of a leak
or other axle repair is required.
TOWING THE VEHICLE ON
FOUR WHEELS
Emergency Towing WARNING:
If your vehicle has a
steering wheel lock make sure the
ignition is in the accessory or on position
when being towed.

BREAKING-IN
Tires
New tires need to be run-in for
approximately 300 mi (500 km). During
this time, you may experience different
driving characteristics.
Brakes and Clutch
Avoid heavy use of the brakes and clutch
if possible for the first
100 mi (150 km) in
town and for the first 1,000 mi (1,500 km)
on freeways.
Engine
Avoid driving too fast during the first
1,000 mi (1,500 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Ground Clearance
GT Performance Package Level 2 Only
Since ground clearance is reduced, use
caution when approaching curbs or curb
stops from the front and rear as vehicle
damage may occur. Additionally, when
crossing speed bumps or driveway curbs,
you should approach at a 45 degree angle
to reduce the risk of vehicle damage.
Your vehicle carries the same warranty as
other Ford models. Damage caused by
accidents, crashes or objects striking the
vehicle, including driving through a car
wash, or misuse of the vehicle, such as
driving over curbs, overloading or racing is
not covered under the new vehicle limited
warranty. See the Warranty Guide for
complete information. REDUCED ENGINE
PERFORMANCE WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See
Gauges
(page 81).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See
Engine
Coolant Check (page 237).
5. Have your vehicle checked as soon as possible.

Reduced Vehicle Top Speed
Your vehicle's ability to reach and maintain
top speed is partially dependent upon
ambient temperature. Under certain
environmental conditions, your vehicle's
top speed may be reduced to protect
powertrain components.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle.
There are some things to keep in mind that
may improve your fuel economy:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back
home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
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.
COLD WEATHER
PRECAUTIONS
The functional operation of some
components and systems can be affected
at temperatures below -13°F (-25°C).
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 front
rocker area of your vehicle.
