Ford Fusion Hybrid (2014 year). Manual — part 46

Troubleshooting

Why is the feature not available (line markings are gray) when I can see the lane markings

on the road?

Vehicle speed is outside the operational range of the feature

Sun is shining directly into the camera lens

Quick intentional lane change

Staying too close to the lane marking

Driving at high speeds in curves

Previous feature activation happened within the last one second

Ambiguous lane markings (mainly in construction zones)

Rapid transition from light to dark or vice versa

Sudden offset in lane markings

ABS or AdvanceTrac activation

Camera blockage due to dirt, grime, fog, frost or water on the windshield

Driving too close to the vehicle in front of you

Transitioning between no lane markings to lane markings or vice versa

Standing water on the road

Faint lane markings (partial yellow lane markings on concrete roads)

Lane width too narrow or too wide

Camera not calibrated after a windshield replacement

Driving on tight roads or on uneven roads

Driving Aids

Why does the vehicle not come back into the middle of the lane always, as expected, in

the Aid or Aid + Alert mode?

High cross winds

Large road crown

Rough roads, grooves, shoulder drop-offs

Heavy uneven loading of the vehicle or improper tire inflation pressure

If the tires have been exchanged (including snow tires), or the suspension has been
modified

BLIND SPOT MONITOR

Blind Spot Information System
(BLIS®) with Cross Traffic Alert

(If

Equipped)

WARNING

To help avoid injuries, NEVER use the
BLIS as a replacement for using the
interior and exterior mirrors and

looking over your shoulder before changing
lanes. BLIS is not a replacement for careful
driving and only an assist.

BLIS aids you in detecting vehicles that
may have entered the blind spot zone (A).
The detection area is on both sides of the
vehicle, extending rearward from the
exterior mirrors to approximately 10 feet
(3 meters) beyond the bumper. The
system alerts you if certain vehicles enter
the blind spot zone while driving.

Cross traffic alert warns you of vehicles
approaching from the sides when the
transmission is in R (Reverse).

Note: BLIS is not designed to prevent
contact with other vehicles or objects; or to
detect parked vehicles, people, animals or
infrastructure (fences, guardrails, trees,
etc.). It is designed to alert the driver to
vehicles in the blind zones.

Note: When a vehicle passes quickly
through the blind zone, typically fewer than
two seconds, the system does not trigger.

Using the Systems

BLIS turns on when the vehicle is started
and is driven forward above 5 mph (8
km/h); it remains on while the transmission
is in D (Drive) and N (Neutral). If shifted
out of D (Drive) or N (Neutral), the system
enters cross traffic alert mode. Once
shifted back into D (Drive), BLIS turns back
on when the vehicle is driven above 5 mph
(8 km/h).

Driving Aids

Note: BLIS does not function in R (Reverse)
or P (Park) or provide any additional
warning when a turn signal is on.

Note: Cross traffic alert detects
approaching vehicles from up to 45 feet (14
meters) away though coverage decreases
when the sensors are blocked. Reversing
slowly helps increase the coverage area and
effectiveness.

Note: For manual transmission vehicles,
CTA will be active only if the transmission
is in Reverse. If the vehicle is rolling
backwards and the transmission is not in
Reverse then CTA will not be active.

WARNING

To help avoid personal injury, NEVER
use the cross traffic alert system as
a replacement for using the interior

and exterior mirrors and looking over your
shoulder before backing out of a parking
space. Cross traffic alert is not a
replacement for careful driving and only
an assist.

In this first example, the left sensor is only
partially obstructed; zone coverage is
nearly maximized.

Zone coverage also decreases when
parking at shallow angles. Here, the left
sensor is mostly obstructed; zone coverage
on that side is severely limited.

System Lights and Messages

E142442

The BLIS and cross traffic alert systems
illuminate a yellow alert indicator in the
outside mirror on the side of the vehicle
the approaching vehicle is coming from.

Note: The alert indicator dims when
nighttime darkness is detected.

Cross traffic alert also sounds an audible
warning and a message appears in the
information display indicating a vehicle is
coming from the right or left. Cross traffic
alert works with the reverse sensing
system which sounds its own series of
tones. See Parking Aid (page 167).

System Sensors

WARNING

Just prior to the system recognizing
a blocked condition and alerting the
driver, the number of missed objects

will increase. To help avoid injuries, NEVER
use the BLIS as a replacement for using
the side and rear view mirrors and looking
over your shoulder before changing lanes.
BLIS is not a replacement for careful
driving and only an assist.

Note: It is possible to get a blockage
warning with no blockage present; this is
rare and known as a false blockage warning.
A false blocked condition either
self-corrects or clears after a key cycle.
