Operating AWD Vehicles With Spare
or Mismatched Tires
WARNING
Only use replacement tires and wheels
that are the same size, load index,
speed rating and type (such as P-metric
versus LT-metric or all-season versus
all-terrain) as those originally provided by
Ford. The recommended tire and wheel size
may be found on either the Safety
Compliance Certification Label (affixed to
either the door hinge pillar, door-latch post,
or the door edge that meets the door-latch
post, next to the driver’ s seating position), or
the Tire Label which is located on the B-Pillar
or edge of the driver’ s door. If this
information is not found on these labels, then
you should contact your authorized dealer
as soon as possible. Use of any tire or wheel
not recommended by Ford can affect the
safety and performance of your vehicle,
which could result in an increased risk of loss
of vehicle control, vehicle rollover, personal
injury and death. A spare tire of a different size other than the
tire provided should never be used. The
AWD system may disable automatically and
enter front-wheel drive only mode to protect
driveline components if a non-full sized tire
is installed. This condition may display an
AWD OFF message in the information
display. If there is an AWD OFF message in
the information display from using a non-full
sized spare tire, this indicator should turn off
after reinstalling the repaired or replaced
normal road tire and cycling the ignition off
and on. It is recommended to reinstall the
repaired or replaced road tire as soon as
possible.
Major dissimilar tire sizes between the front
and rear axles (for example, 17 inch low
profile tires on the front axle and 22 inch high
profile tires on the rear axle) could cause the
AWD system to stop functioning and default
to front-wheel drive or damage the AWD
system. However, the AWD system is
capable of tolerating any combination of new
and worn tires of the same original tire size.
For example, using 3 worn tread tires and 1
new tread tire all of the same original tire
size, can be tolerated by the AWD system. Driving In Special Conditions With All-
Wheel Drive (AWD)
AWD vehicles are equipped for driving on
sand, snow, mud and rough roads and have
operating characteristics that are somewhat
different from conventional vehicles, both on
and off the highway.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Lower gear operation
will maximize the engine and transmission
cooling capability.
Under severe operating conditions, the A/C
may cycle on and off to protect overheating
of the engine.
Basic operating principles in special
conditions
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• Be extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
194
Continental (CPL) Canada/United States of America, enUSA, First Printing All-Wheel Drive
(If Equipped)

If Your Vehicle Goes Off the Edge of the
Pavement
•
If your vehicle goes off the edge of the
pavement, slow down, but avoid severe
brake application, ease the vehicle back
onto the pavement only after reducing
your speed. Do not turn the steering
wheel too sharply while returning to the
road surface.
• It may be safer to stay on the apron or
shoulder of the road and slow down
gradually before returning to the
pavement. You may lose control if you
do not slow down or if you turn the
steering wheel too sharply or abruptly.
• It often may be less risky to strike small
objects, such as highway reflectors, with
minor damage to your vehicle rather than
attempt a sudden return to the pavement
which could cause the vehicle to slide
sideways out of control or rollover.
Remember, your safety and the safety of
others should be your primary concern. If Your Vehicle Gets Stuck WARNINGS
Always set the parking brake fully and
make sure you shift the gearshift lever
to park (P). Switch the ignition off and remove
the key whenever you leave your vehicle. If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be working
properly. Have your vehicle checked as soon
as possible. Do not spin the wheels at over 34 mph
(55 km/h). The tires may fail and injure
a passenger or bystander. Note:
Do not rock the vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock the vehicle for more than
a few minutes or damage to the transmission
and tires may occur or the engine may
overheat. If your vehicle gets stuck in mud or snow it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear.
If your vehicle is equipped with
AdvanceTrac® with Roll Stability Control™, it
may be beneficial to disengage the
AdvanceTrac® with Roll Stability Control™
system while attempting to rock the vehicle.
Emergency Maneuvers
•
In an unavoidable emergency situation
where a sudden sharp turn must be
made, remember to avoid "over-driving"
your vehicle (that is, turn the steering
wheel only as rapidly and as far as
required to avoid the emergency).
Excessive steering will result in less
vehicle control, not more. Additionally,
smooth variations of the accelerator
and/or brake pedal pressure should be
utilized if changes in vehicle speed are
called for. Avoid abrupt steering,
195
Continental (CPL) Canada/United States of America, enUSA, First Printing All-Wheel Drive
(If Equipped)

acceleration or braking which could result
in an increased risk of loss of vehicle
control, vehicle rollover and/or personal
injury. Use all available road surface to
return the vehicle to a safe direction of
travel.
• In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
• If the vehicle goes from one type of
surface to another (that is, from concrete
to gravel) there will be a change in the
way the vehicle responds to a maneuver
(steering, acceleration or braking). Again,
avoid these abrupt inputs.
Sand
Most of the time traction control improves
tire traction by managing wheel slip through
Brake, Engine, and AWD calibrations.
However, during low speed driving, disabling
traction control in deep sand can help keep
the wheels moving to maintain vehicle
momentum. When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly and
avoid spinning the wheels.
Do not drive your vehicle in deep sand for
an extended period of time. This could cause
the AWD system to overheat and default to
front-wheel drive. If this occurs, an AWD OFF
message displays in the information display.
To resume normal AWD function as soon as
possible, stop the vehicle in a safe location
and stop the engine for at least 10 minutes.
After the engine has been restarted and the
AWD system has adequately cooled, the
AWD OFF message turns off and normal
AWD function returns. In the event the
engine is not stopped, the
AWD OFF
message turns off when the system cools
and normal AWD function returns.
When driving at slow speeds in deep sand
under high outside temperatures, use L (Low)
gear when possible. L (Low) gear operation
will maximize the engine and transmission
cooling capability. Under severe operating conditions, the A/C
may cycle on and off to protect overheating
of the engine.
Avoid excessive speed because vehicle
momentum can work against you and cause
the vehicle to become stuck to the point that
assistance may be required from another
vehicle. Remember, you may be able to back
out the way you came if you proceed with
caution.
Mud and Water
If you must drive through high water, drive
slowly. Traction or brake capability may be
limited.
When driving through water, determine the
depth; avoid water higher than the bottom
of the wheel rims (for cars) or the bottom of
the hubs (for trucks) (if possible) and proceed
slowly. If the ignition system gets wet, the
vehicle may stall.
196
Continental (CPL) Canada/United States of America, enUSA, First Printing All-Wheel Drive
(If Equipped)

Once through water, always try the brakes.
Wet brakes do not stop the vehicle as
effectively as dry brakes. Drying can be
improved by moving your vehicle slowly
while applying light pressure on the brake
pedal.
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even AWD vehicles can lose traction
in slick mud. As when you are driving over
sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does
slide, steer in the direction of the slide until
you regain control of the vehicle.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
causes an imbalance that could damage
drive components.
Note:
Driving through deep water may
damage the transmission.
If the front or rear axle is submerged in water,
have the power transfer unit (PTU) or rear
axle serviced by an authorized dealer. Driving on Hilly or Sloping Terrain
Note:
Avoid driving crosswise or turning on
steep slopes or hills. A danger lies in losing
traction, slipping sideways and possibly
rolling over. Whenever driving on a hill,
determine beforehand the route you will use.
Do not drive over the crest of a hill without
seeing what conditions are on the other side.
Do not drive in reverse over a hill without
the aid of an observer.
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down.
When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If you do stall out, do not try to turnaround
because you might roll over. It is better to
back down to a safe location. Apply just enough power to the wheels to
climb the hill. Too much power will cause the
tires to slip, spin or lose traction, resulting in
loss of vehicle control.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating. Do
not descend in neutral; instead, disengage
overdrive or manually shift to a lower gear.
When descending a steep hill, avoid sudden
hard braking as you could lose control. The
front wheels have to be turning in order to
steer the vehicle.

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 Wheels
(page 338).
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, your brake lamps
may flash during heavy braking. Following
this, your hazard lights may also flash when
your vehicle comes to a stop. See
Warning Lamps and
Indicators (page 105). 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
illuminates when 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.

Automatic release - drive away release
Your vehicle will automatically release the
parking brake if all of the following conditions
exist:
•
The driver door is closed.
• The accelerator pedal is pressed.
• There are no faults detected in the
parking brake system.
Note: If the electric parking brake warning
lamp stays illuminated, the electric parking
brake will not automatically release. You
must release the electric parking brake using
the electric parking brake switch while your
foot is on the brake and the ignition is on.
The brake system warning lamp will go off
to confirm that the electric parking brake has
been released.
Note: The electric parking brake drive away
release makes starting on a hill easier. This
feature will release the parking brake
automatically when the vehicle has sufficient
torque force to move up the hill. To assure
drive away release when starting uphill,
press the accelerator pedal quickly. Driving with a Trailer
Depending on the slope and the weight of
the trailer, your vehicle and trailer may roll
backwards slightly when you start on a slope.
To prevent this from happening, do the
following:
1. Pull the switch up and hold it in this
position.
2. Accelerate your vehicle, then release the
switch when you notice that the engine
has developed sufficient driving force.
Battery With No Charge WARNING
You will not be able to apply or release
the electric parking brake if the battery
is low or has no charge. If the battery is low or has no charge, use
jumper cables and a booster battery.AUTO HOLD WARNINGS
The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking brake. You must remain in your vehicle when
the system turns on. At all times, you
are responsible for controlling your vehicle,
supervising the system and intervening, if
required. Failure to take care may result in
the loss of control of your vehicle, serious
personal injury or death. The system will turn off if a malfunction
is apparent or if you rev the engine
excessively. Failure to take care may result
in the loss of control of your vehicle, serious
personal injury or death. Auto Hold is a feature that uses your
vehicle's brake to hold your vehicle at a stop
once your vehicle has reached a standstill
condition. For example, Auto Hold can assist
you while stopping at traffic lights or while
in traffic jams by holding the brake pressure
for you once you bring your vehicle to a stop.
204

2.
Release the brake pedal. The Auto Hold
(ACTIVE) indicator light remains
illuminated in the information display and
Auto Hold will hold your vehicle at a stop.
3. When you press the accelerator pedal, Auto Hold will release the brakes and
you will be able to drive off. Once you
drive off, the green Auto Hold (ACTIVE)
indicator no longer illuminates in the
information display.
Note: The Stop/Start system (if equipped)
may stop the engine when you press the
brake pedal. If this occurs, it will restart once
you press the accelerator pedal. Auto Hold
still holds your vehicle at a standstill with the
engine off.

Continental (CPL) Canada/United States of America, enUSA, First Printing Brakes

PRINCIPLE OF OPERATION
The traction control system helps avoid drive
wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels and,
when needed, reduces engine power at the
same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL WARNING
The stability and traction control light
illuminates steadily if the system
detects a failure. Make sure you did not
manually disable the traction control system
using the information display controls or the
switch. If the stability control and traction
control light is still illuminating steadily, have
the system serviced by an authorized dealer
immediately. Operating your vehicle with the
traction control disabled could lead to an
increased risk of loss of vehicle control,
vehicle rollover, personal injury and death. The system automatically turns on each time
you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note:
When you switch traction control off,
stability control remains fully active. Switching the System Off
When you switch the system off or on, a
message appears in the information display
showing system status.
You can switch the system off by either using
the information display controls or the switch.
Using the Information Display Controls
You can switch this feature off or on in the
information display. See General Information
(page 110).
Using a Switch
(If Equipped)
Use the traction control switch on the
instrument panel to switch the system off or
on.
System Indicator Lights and Messages The stability and traction control

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving braking
system, aftermarket roof racks,
suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability control
system. In addition, installing any stereo
loudspeakers may interfere with and
adversely affect the electronic stability
control system. Install any aftermarket stereo
loudspeaker as far as possible from the front
center console, the tunnel, and the front
seats in order to minimize the risk of
interfering with the electronic stability control
sensors. Reducing the effectiveness of the
electronic stability control system could lead
to an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death. WARNINGS
Remember that even advanced
technology cannot defy the laws of
physics. It’ s always possible to lose control
of a vehicle due to inappropriate driver input
for the conditions. Aggressive driving on any
road condition can cause you to lose control
of your vehicle increasing the risk of personal
injury or property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires have
exceeded their ability to grip the road; this
could reduce the operator’ s ability to control
the vehicle potentially resulting in a loss of
vehicle control, vehicle rollover, personal
injury and death. If your electronic stability
control system activates, SLOW DOWN. The system automatically turns on each time
you switch the ignition on.
If a fault occurs in either the stability control
or the traction control system, you may
experience the following conditions:•
The stability and traction control light
illuminates steadily.
• The stability control and traction control
systems do not enhance your vehicle's
ability to maintain traction of the wheels.
• The adaptive steering system (if
equipped) automatically changes the
steering function to a fixed steering ratio.
See Steering (page 251).
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the system applies higher
brake force.
