Ford Transit (2018 year). Manual — part 38

Switching the System On and Off

Vehicles with Manual Transmission

You can switch this feature on or off in the
information display. The system
remembers the last setting when you start
your vehicle.

Vehicles with Automatic Transmission

You cannot turn the system on or off.
When you switch the ignition on, the
system automatically turns on.

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 94).

Using a Switch

(If Equipped)

Use the traction control switch on the
instrument panel to switch the system off
or on.

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 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.

Side-Wind Stabilization

The system applies the brakes on one side
of your vehicle to reduce the effect of a
sudden side-wind gust on your vehicle's
path. When the system turns on, the
stability and traction control light flashes,
and a message may appear in the
information display. You may notice a
slight deceleration and may still need to
make a steering correction to maintain the
intended vehicle path. The system does
not turn on for a continuous side-wind or
during turns.

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 156).

USING STABILITY CONTROL

The system automatically turns on each
time you switch the ignition on.

You cannot switch the stability control and
roll stability control systems off, but when
you shift into reverse (R), the systems
deactivate.

You can switch the traction control system
off or on. See Using Traction Control
(page 156).
