2011 FORD EXPLORER cruise control

Following a vehicle
WARNING:When following a vehicle in front of you, the vehicle
will not decelerate automatically to a stop, nor will the vehicle
always decelerate quickly enough to avoid a collision without driver
intervention. Always apply the brakes when necessary. Failing to do so
may result in a collision, serious injury or death.
When a vehicle ahead of you enters the same lane or a slower vehicle is
ahead in the same lane, the vehicle speed will adjust automatically to
maintain a preset gap distance. The distance setting is adjustable, refer
toSetting the gap distancein this section.
The lead vehicle graphic will be illuminated.
The vehicle will maintain a constant distance between the vehicle ahead
until:
•The vehicle in front of you accelerates to a speed above the set speed.
•The vehicle in front of you moves out of your lane or out of view.
•The vehicle speed falls below 16 mph (26 km/h).
•A new gap distance is set.
The vehicle brakes will be automatically applied to slow the vehicle to
maintain a safe distance between the vehicle in front. The maximum
braking which is applied by the ACC system is limited and can be
overridden by the driver applying the brakes.
If the ACC system predicts that its
maximum braking level will not be
sufficient, an audible warning will
sound while the ACC continues to
brake. This is accompanied by a
heads-up display; a red warning bar
illuminating on the windshield. The driver should takeimmediate
action.
Note:The brakes may emit a sound when they are being modulated by
the adaptive cruise control system.
WARNING:Adaptive cruise control only warns of vehicles
detected by the radar sensor. In some cases there may be no
warning or the warning may be delayed. The driver should always
apply the brakes when necessary. Failing to do so may result in a
collision, serious injury or death.

Setting the gap distance
The distance between your vehicle
and the vehicle in front of you can
be decreased or increased by
pressing the GAP control up or
down. The selected gap will be
displayed in the message center as shown by the bars in the graphic.
Four gap distance settings are available.

Each time the vehicle is restarted, the last chosen gap for the current
driver will be automatically selected.
Note:It is the driver’s responsibility to select a gap appropriate to the
driving conditions.
Disengaging adaptive cruise control
Press the brake pedal or press CNCL to disengage the adaptive cruise
control. The last set speed will be displayed with a strikethrough.
Disengaging the adaptive cruise control will not erase your previous set
speed.
Overriding adaptive cruise control
WARNING:Whenever the driver is overriding the ACC by
pressing the accelerator pedal, the ACC will not automatically
apply the brakes to maintain separation from any vehicle ahead.
The set speed and gap distance can be overridden by pressing the
accelerator pedal.
When the driver is overriding ACC, the green
ACC light is
illuminated, and the follow vehicle is not displayed in the message
center. When the accelerator is released, the ACC function will operate
again and vehicle speed will decrease to the set speed, or a lower speed
if following a slower vehicle.

Changing the set speed
There are three ways to change the set speed:
•Accelerate or brake to the desired speed and press SET upward and
release.
•Increase or decrease the speed by holding SET upward or downward
until the desired set speed is shown on the message center. The
vehicle speed will gradually change to the selected speed.
•Increase or decrease the speed in increments of 1 mph (2 km/h) by
briefly pressing the SET upward or downward.
The ACC may apply the brakes to slow the vehicle down to the new set
speed. The set speed will display continuously in the message center
while ACC is active.
Resuming the set speed
Press and release RES/CNCL. This will automatically return the vehicle
to the previously set speed. The set speed will display continuously in
the message center while ACC is active.
Note:Resume should only be used if the driver is aware of the set speed
and intends to return to it.
Low speed automatic cancellation
ACC is not functional at vehicle speeds below 16 mph (26 km/h). Once
the vehicle speed drops below 16 mph (26 km/h), an audible alarm will
sound and the automatic braking will be released.
Hilly condition usage
It is recommended that the driver select a lower gear position when ACC
is active in situations such as prolonged downhill driving on steep grades
(i.e., driving in mountainous areas). In these situations, additional engine
braking is needed to reduce the load on the vehicle’s regular brake
system to prevent them from overheating. For more information,
referenceAutomatic transmission operationin theDrivingchapter.
Note:If ACC is applying brakes for an extended period of time, an
audible alarm will sound and ACC will shut down. This is to allow the
brakes to cool down. When the brakes have cooled down, the ACC will
again function normally.
Turning off cruise control
Press OFF to turn off the cruise control.
Note:When you turn off the cruise control or the ignition, your cruise
control set speed memory is erased.

Cause Action
The surface of the radar in the grille
is dirty or obstructed in some wayClean the grille surface in front of
the radar or remove the object
causing the obstruction
The surface of the radar in the grille
is clean but the message remains in
the displayWait a short time. It may take
several minutes for the radar to
detect that it is no longer obstructed
Heavy rain or snow is interfering
with the radar signalsDo not use ACC in these condition
because it may not detect, warn, or
respond to potential collisions.
Swirling water, or snow or ice on the
surface of the road may interfere
with the radar signalsDo not use ACC in these condition
because it may not detect, warn, or
respond to potential collisions.
WARNING:Do not use ACC when towing a trailer with brake
controls. Aftermarket trailer brakes will not function properly
when ACC is activated because the brakes are electronically controlled.
Failing to do so may result in loss of vehicle control, which could result
in serious injury.
WARNING:Do not use tires sizes other than those
recommended because this can affect the normal operation of
ACC. Failing to do so may result in a loss of vehicle control, which
could result in serious injury.
Switching to normal cruise control
You can manually change from adaptive cruise control (ACC) to normal
cruise control through the message center. Refer toMessage centerin
theInstrument Clusterchapter. If normal cruise control is selected, the
ACC indicator light will be replaced with a
cruise control indicator
light. The gap setting will not be displayed, the system will not
automatically respond to lead vehicles and automatic braking will not be
activated. The system will default to ACC when the engine is started.
WARNING:Normal cruise control will not brake due to slower
vehicles. Always be aware of which mode is selected and apply
the brakes when necessary.

1. Grass/Gravel/Snow
2. Sand
3. Mud/Ruts
4. Normal
•Normal - This mode is for on-road conditions. If not already active,
Normal should be selected before driving on surfaces which are similar
to a hard road surface. This mode should be selected once the need
for a special mode has passed. Use Normal mode when towing a
trailer.
Note:Cruise control is available only in Normal and Snow modes.
•Grass/Gravel/Snow - This mode should be used where a firm surface is
covered with loose or slippery material. Surfaces covered in packed
snow, ice, water, grass, gravel, or a thin coating of sand for example.
For deep gravel, it is recommended that the Sand mode is selected. If
the vehicle is unable to gain traction in deep snow, switching traction
control off may help. Traction control should be switched on again as
soon as the difficulty is overcome. SeeSwitching Off AdvanceTrac
with RSCearlier in this chapter.
Note:The Mud/Ruts and Sand modes are for off-road use only.
Note:Curve Control is unavailable when the Mud/Ruts or Sand modes
are selected.
•Sand - This mode should be used for soft dry sand, or deep gravel
terrain. If the sand to be crossed is damp/wet, and sufficiently deep
enough to cause the wheels to sink into the surface, the Mud/Ruts
mode should be selected.
•Mud/Ruts - This mode should be used for muddy, rutted, soft, or
uneven terrain.
If the terrain management system becomes inoperable, it may not be
possible to select specific modes and a message will be displayed. If the
TMS becomes inoperable due to a system malfunction, all of the mode
indicators on the control will turn off and the message center will display
one of the following messages.1

•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between the top gears occurs. Unnecessary
shifting of this type could result in reduced fuel economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example; bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
