WARNING
Switching off the engine when the
vehicle is still moving will result in a
loss of brake and steering assistance.
The steering will not lock, but higher effort
will be required. When the ignition is
switched off, some electrical circuits,
including air bags, warning lamps and
indicators may also be off. If the ignition
was turned off accidentally, you can shift
into neutral (N) and re-start the engine. Vehicles with an Ignition Key
1.
Shift into neutral and use the brakes to
bring your vehicle to a safe stop.
2. When your vehicle has stopped, shift into park (P) and switch the ignition
off.
3. Apply the parking brake.
Vehicles with Keyless Start
1. Shift into neutral and use the brakes to
bring your vehicle to a safe stop.
2. When your vehicle has stopped, shift into park (P).
3. Press and hold the push button ignition
switch, or press it three times within
two seconds.
4. Apply the parking brake.
Guarding Against Exhaust Fumes WARNING
Exhaust leaks may result in entry of
harmful and potentially lethal fumes
into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes. Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods, we
recommend that you do one of the
following:
•
Open the windows at least 1 in (3 cm).
• Set your climate control to outside air.
ENGINE BLOCK HEATER (If
Equipped) WARNINGS
Failure to follow engine block heater
instructions could result in property
damage or serious personal injury.
Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk
of electrical shock. Do not fully close the hood, or allow
it to drop under its own weight when
using the engine block heater. This
could damage the power cable and may
cause an electrical short resulting in fire,
injury and property damage. Note:
The heater is most effective when
outdoor temperatures are below 0°F
(-18°C).
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source.

The transfer case supples power to all four
wheels. On four-wheel drive vehicles, the
transfer case allows you to select different
4WD modes when necessary. You can find
information on transfer case operation and
shifting procedures in this chapter. You can
find information on transfer case
maintenance in the Maintenance chapter.
You should become thoroughly familiar
with this information before you operate
your vehicle.
Four-wheel drive (when you select a 4WD
mode) uses all four wheels to power your
vehicle. This increases traction, enabling
you to drive over terrain and road
conditions that a conventional two-wheel
drive vehicle cannot.
Basic Operating Principles
•
Do not use 4H or 4L on dry, hard
surfaced roads. Doing so will produce
excessive noise, increase tire wear and
may damage drive components. 4H or
4L modes are only intended for
consistently slippery or loose surfaces.
• Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• When driving your vehicle on surfaces
made slippery by loose sand, water,
gravel, snow or ice proceed with care.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce your
vehicle speed and avoid severe braking.
When your vehicle speed decreases, ease
your vehicle back onto the road. Do not
turn the steering wheel sharply while
returning your vehicle to the road.
It may be safer to stay on the shoulder of
the road and slow down gradually before
returning to the road. You may lose control
if you do not slow down or if you turn the
steering wheel too sharply or abruptly. It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than
attempt a sudden return to the road which
could cause your vehicle to slide sideways
out of control or roll over. Remember, your
safety and the safety of others should be
your primary concern.
If your vehicle gets stuck
WARNING
Do not spin the wheels at over 35
mph (56 km/h). The tires may fail
and injure a passenger or bystander.
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute, 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.
Emergency Maneuvers
In an unavoidable emergency situation
where a sudden sharp turn must be made,
remember to avoid over-driving your
vehicle (i.e. turn the steering wheel only as
rapidly and as far as required to avoid the
emergency). Excessive steering can result
in loss of vehicle control. Apply smooth
pressure to the accelerator pedal or brake
pedal when changes in vehicle speed are
required. Avoid abrupt steering,
acceleration and braking. This could result
in an increased risk of vehicle roll over, loss
of vehicle control and personal injury. Use
all available road surface to bring your
vehicle to a safe direction of travel.

Expedition (TB7) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Four-Wheel Drive (If Equipped)

Note:
Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll 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 your vehicle stalls, do not try to turn
around because this could cause vehicle
roll over. It is better to reverse back 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. Disengage
overdrive or move the transmission
selector lever 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
your vehicle.
If your vehicle has anti-lock brakes, apply
the brakes steadily. Do not pump the
brakes.
Driving on Snow and Ice
WARNING
If you are driving in slippery
conditions that require tire chains or
cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end of
your vehicle slides while cornering, steer in
the direction of the slide until you regain
control of your vehicle. Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.

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 270). See
Warning Lamps and
Indicators (page 87).
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 may pulse and may travel
further. Maintain pressure on the brake
pedal. You may also hear a noise from the
system. This is normal.
The anti-lock braking system will not
eliminate the risks when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.

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. 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.
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.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.

Switching the System Off and On
One or both systems can be switched off
temporarily by using the information
display control; See Information
Displays (page 91). . When you switch off
the Blind Spot Information System, you
will not receive alerts and the information
display will display a system off message.
The yellow alert indicator in the outside
mirror will also flash twice. The system
switches back on whenever you switch the
ignition on.
You can also have the Blind Spot
Information System switched off
permanently at an authorized dealer. Once
switched off permanently, the system can
only be switched back on at an authorized
dealer.
STEERING
Electric Power Steering WARNINGS
The electric power steering system
has diagnostic checks that
continuously monitor the system. If
a fault is detected, a message displays in
the information display. Stop your vehicle
as soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked by an authorized dealer. If the system detects an error, you
may not feel a difference in the
steering, however a serious condition
may exist. Obtain immediate service from
an authorized dealer, failure to do so may
result in loss of steering control. Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems.

DRIVE CONTROL
Driver Select Suspension (If Equipped)
Driver select suspension delivers a unique
driving experience through a suite of
sophisticated electronic vehicle systems.
These systems continuously monitor your
driving inputs and the road conditions to
optimize ride comfort, steering and
handling.
Driver select suspension consists of the
following systems:
• Continuously controlled damping
dynamically adjusts the shock
absorbers stiffness in real time to
match the road surface and driver
inputs. This system continuously
monitors your vehicle ’s motion (roll,
pitch, bounce), suspension position,
load, speed, road conditions, and
steering to adjust the suspension
damping for optimal vehicle control.
• Electronically power-assisted steering
adjusts steering effort and feel based
on your vehicle speed and your inputs.
The configuration remains active until
modified from the main menu on the
information display. See
General
Information (page 91). Modes:
•
Comfort – Provides a more relaxed
driving experience, maximizing comfort.
Your steering effort decreases and the
suspension movement is more fluid.
Comfort mode is ideal when you desire
enhanced traveling comfort.
• Normal – Delivers a balanced
combination of comfortable, controlled
ride and confident handling. This mode
provides an engaging drive experience
and a direct connection to the road
without sacrificing any of the
composure demanded from your
vehicle.
• Sport – Provides a sportier driving
experience. The suspension stiffens,
with an emphasis on handling and
control. The engine responds more
directly to your inputs. Sport mode is
ideal for use during more spirited
driving.
SELF-LEVELING SUSPENSION
The self-leveling suspension system is
designed to improve ride, handling and
general vehicle performance during:
• Certain road conditions
• Steering maneuvers
• Braking
• Acceleration
• Towing
This system keeps the rear of your vehicle
at a constant level through a hydraulic
pump inside each rear shock. Depending
on the payload or road surface conditions
it will take approximately 2 mi (3.2 km) for
the leveling to complete.
