2020 FORD RANGER traction control

The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
Maintain steering wheel control at all
times, especially in rough terrain. Since
sudden changes in terrain can result in
abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes of the
steering wheel.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the
area. To maintain steering and braking
control of your vehicle, you must have all
four wheels on the ground and they must
be rolling, not sliding or spinning.
Driving Off-Road With Truck and
Utility Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive when
your vehicle is moving can cause some
momentary clunk or ratchet sounds. This is
the front drivetrain coming up to speed.
Note: Your vehicle may have a front air
dam. Due to low ground clearance, you can
damage it when taking your vehicle off-road.
You can take the air dam off by removing
the bolts that secure it.
Note: Momentarily releasing the
accelerator pedal when a shift in progress
message displays, should improve
engagement or disengagement
performance.
Four-wheel drive vehicles are specially
designed for driving on sand, snow, mud
and rough terrain and have operating
characteristics that are somewhat
different from conventional vehicles, both
on and off the road. The transfer case supplies 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 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
•
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.
• Do not use 4H or 4L on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and
may damage drive components. 4H or
4L modes are only for consistently
slippery or loose surfaces.
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
sharply turn the steering wheel when
returning your vehicle to the road.
It may be safer to stay on the shoulder of
the road and gradually slow down before
returning to the road. You may lose control
if you do not slow down or if you too
sharply or abruptly turn the steering wheel.

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.
Emergency Maneuvers
In an unavoidable emergency situation
where a sudden sharp turn must be made,
remember to avoid over-driving your
vehicle and 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 you require changes in vehicle
speed. 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 the
available road surface to bring your 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 your vehicle goes from one type of
surface to another such as concrete to
gravel there can be a change in the way
your vehicle responds to a maneuver using
steering, acceleration or braking.
Driving in Special Conditions with
Four-Wheel Drive
Four-wheel drive vehicles are suitable 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
freeway.
When driving at slow speeds off road under
high load conditions, use a low gear when
possible. Low gear operation maximizes
the engine and transmission cooling
capability.
Basic Operating Principles
When driving your vehicle on surfaces
made slippery by loose sand, water, gravel,
snow or ice proceed with care.
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Shift to a lower gear and drive steadily
through the terrain. Apply the accelerator
slowly and avoid excessive wheel slip.
Do not drive your vehicle in deep sand for
an extended period of time. This can cause
the system to overheat.
To resume operation, switch the ignition
off and allow the system to cool down for
a minimum of 15 minutes.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Low gear operation
maximizes the engine and transmission
cooling capability.
Avoid driving at excessive speeds, this
causes vehicle momentum to work against
you and your vehicle could 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
Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive vehicles can
lose traction in slick mud. If your vehicle
does slide, steer in the direction of the slide
until you regain control of your vehicle.

After driving through mud, clean off residue
stuck to rotating driveshafts and tires.
Excess mud stuck on tires and rotating
driveshafts can cause an imbalance that
could damage drive components.
Water
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, try the brakes. Wet
brakes do not stop your vehicle as
effectively as dry brakes. Drying improves
by applying light pressure to the brake
pedal when slowly moving.
Note:
Driving through deep water may
damage the transmission. If the front or rear
axle is submerged in water, the axle
lubricant and power transfer unit lubricant
should be checked and changed if
necessary. “Tread Lightly
” is an educational program
designed to increase public awareness of
land-use regulations and responsibilities
in our nations wilderness areas. Ford Motor
Company joins the U.S. Forest Service and
the Bureau of Land Management in
encouraging you to help preserve our
national forest and other public and private
lands by “treading lightly. ” Driving on Hilly or Sloping Terrain
Although natural obstacles may make it
necessary to travel diagonally up or down
a hill or steep incline, you should drive
straight up or straight down.
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 intend to 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.
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 could cause
the tires to slip, spin or lose traction,
resulting in loss of vehicle control. 166

ELECTRONIC LOCKING
DIFFERENTIAL (IF EQUIPPED)
Note: Do not operate the system on dry
hard surface roads. Doing so could lead to
excessive tire noise and wear. Use the
system only on consistently slippery or loose
surfaces.
The system locks the left and right portions
of the rear axle together to form a solid
driving axle, resulting in increased rear
wheel traction in certain conditions.
Press and hold the electronic differential
lock button for 2 seconds to activate the
system.
Note: The lock button is on the center
console. The electronic differential lock can lock
and unlock when the internal gears are
aligned and no torque load is placed on
the differential. To aid alignment, drive the
vehicle in a straight line with the
accelerator pedal released. Alternatively,
drive slowly forward and backward while
moving the steering wheel from side to side
to allow the electronic differential lock to
lock. High vehicle speed and high accelerator
pedal application inhibit the electronic
locking differential system engagement.
Follow the instruction on the instrument
cluster for engagement and
disengagement.
Note:
You can use the system in any drive
mode 2H, 4H or 4L.
Note: When you engage the system, the
Electronic Stability Program (ESP) functions
such as Stability Control, Traction Control,
Hill Descent Control, Emergency stop signal,
Hill Start Assist and Trailer Sway Control
are deactivated, the ESP Off indicator
illuminates, and the HDC on indicator turns
off.
Note: When the anti-lock braking system
is operating, the system disengages.
The electronic locking differential system
can affect various terrain modes. See
Principle of Operation
(page 178).
Operating Electronic Locking
Differential with Spare or
Mismatched Tires
The size of the spare tire can affect the
performance of the electronic locking
differential system. When there is a
significant size difference between the two
rear tires, you could have limited electronic
locking differential functionality. If your
electronic locking differential has difficulty
disengaging, release your accelerator pedal
and turn the steering wheel in the opposite
direction while rolling forward.
Note: We recommend that you engage and
disengage the electronic locking differential
when stopped, and a spare tire is mounted
on the rear axle.

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 The switch for the stability and traction
control system is on the console.
When you switch the system off, a
message and an illuminated icon appear
on the instrument cluster.
Use the switch again to return the traction
control system to normal operation.
Your vehicle may have MyKey restrictions
regarding this feature. See
Principle of
Operation (page 58).
System Indicator Lights and
Messages The stability and traction control
light temporarily illuminates on
engine start-up and flashes:
• When a driving condition activates
either of the systems.
• If a problem occurs in either of the
systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on:
• When you switch the traction control
system off.
• When you select an alternative stability
control mode.

PRINCIPLE OF OPERATION
WARNING: 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. WARNING:
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 the stability control or traction control
system detects a fault, the following may
occur:
•
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 the stability control or traction control
system activates, the following may occur:
• 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 pedal, the
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 helps to prevent your vehicle
skidding or laterally sliding by individually
applying the brakes to one or more wheels
and, if necessary, reducing engine power.
Roll Stability Control
The system helps to prevent rollovers by
detecting your vehicle's roll motion, and
individually applying the brakes to one or
more wheels.
Traction Control
The system enhances your vehicle's ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control
(page 174).

PRINCIPLE OF OPERATION
Using the Terrain Management
System
The terrain management system optimizes
drivability and comfort by maximizing
traction when operating on different types
of terrain.
Press the TM button on the center console
to choose between the following modes:
Note:
Changing terrain modes could
automatically change your 4X4 setting for
optimal performance. Normal - For on-road
conditions. Select this mode
before driving on surfaces which
are similar to a hard road surface or once
the need for a special mode has passed.
Note: This is the default when you switch
on your vehicle and whenever you select 4x2
via the four-wheel drive control. Grass/Gravel/Snow
- For
off-road conditions. Select this
mode where loose or slippery
material such as packed snow, ice, grass,
or a thin layer of gravel or sand covers a
firm surface. If your vehicle cannot gain
traction in deep snow, switching off the
traction control system could help.
Note: Make sure you switch traction control
back on when you regain traction. Mud/Ruts
- For off-road
conditions. Select this mode for
muddy, rutted, soft or uneven
terrain. Sand
- For off-road conditions.
Select this mode in soft dry sand
or deep gravel. If crossing wet
sand that could be sufficiently deep
enough for the wheels to sink into the
surface, select Mud/Ruts mode.
Note: The Grass/Gravel/Snow, Sand and
Mud/Ruts modes are for off-road use only.
Note: The curve control portion of the
AdvanceTrac® system is unavailable when
you select Sand or Mud/Ruts. If the system
becomes inoperable, selecting some modes
may not be possible and a message
displays. If it becomes inoperable due to a
system fault, all of the mode indicators on
the control turn off and one of the following
messages appears in the information
display:
TERRAIN MANAGEMENT SYSTEM
