Ford GT (2018 year). Manual — part 28

HILL START ASSIST

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 turns off if there is a
malfunction or if you excessively rev
the engine.

The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.

When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows you time to move your
foot from the brake to the accelerator
pedal. The brakes release automatically
once the engine develops sufficient torque
to prevent your vehicle from rolling down
the slope. The system activates
automatically on any slope that causes
significant vehicle rollback.

Note: There is no warning lamp to indicate
the system is either on or off.

Using Hill Start Assist

1.

Press the brake pedal to bring your
vehicle to a complete standstill. Keep
the brake pedal pressed.

2. If the sensors detect that your vehicle

is on a slope, the system activates
automatically.

3. When you remove your foot from the

brake pedal, your vehicle will remain
on the slope without rolling away for
about two or three seconds. This hold
time automatically extends if you are
in the process of driving off.

4. Drive off in the normal manner. The

brakes release automatically.

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.

WARNINGS

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 stability and traction control systems
help you to avoid drive wheel spin and loss
of traction. 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 and traction control systems
have several features built into it to help
you maintain control of your vehicle:

AdvanceTrac™ 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.

Traction Control

The system enhances your vehicle’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin.
Traction control settings on your vehicle
are integrated into the AdvanceTrac
Stability Control system.

USING STABILITY CONTROL

AdvanceTrac™ Electronic
Stability Control

The system automatically turns on each
time you switch the ignition on. You can
also use the stability control button on the
center console to adjust the operation of
the AdvanceTrac stability control system.

AdvanceTrac electronic stability control is
disabled when the transmission is in
reverse (R).

The amount of change you can make to
the AdvanceTrac stability control system
depends on the Drive Mode you have
selected.

The following chart describes how much you can change the functionality of
stability control and traction control in each Drive Mode:

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.

System Indicator Lights and Messages

E236447

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.

E236448

The stability and traction control
off light temporarily illuminates
on engine start-up and stays on

when you adjust the operation of the
AdvanceTrac stability control system. The
amount of change you can make to the
AdvanceTrac stability control system
depends on the drive mode you have
selected. The chart found earlier in this
section shows how much you can change
the stability control and traction control
for each drive mode.

Launch Control

Note: Only use this feature in a controlled
environment, such as a track. Launch control
is not for use in normal driving.

Note: Launch control is not available when
in the Wet drive mode.

Your vehicle has a launch control feature
that uses clutch and engine controls to
reduce wheel spin or slip on a hard
acceleration from a standing start.

To operate launch control, your vehicle
must meet the following conditions:
•

You must be in any drive mode other
than Wet drive mode.

•

You must close the doors, front hood
and rear hatch.

•

Your vehicle should be on a level
surface.

•

You must disengage the electric park
brake.

•

You must be at a complete stop with
the brake pedal applied and the
transmission selector in drive (D).
