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
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
When driving on tight roads or on uneven roads
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

•The Sport, optional 265/45ZR20 tires are optimized for performance in
both wet and dry conditions. Ford does not recommend using the
original equipment tires when temperatures drop to about 40°F (5°C)
or below (depending on tire wear and environmental conditions) or in
snow/ice conditions.
•The Sport, optional 265/45ZR20 tires were designed for track use and
may exhibit significantly reduced tread life and increased tire noise
compared to the standard equipment tires under normal driving
conditions. Increasing the front camber settings beyond the factory
settings may further accelerate tread wear and induce tire noise.
•Do not use tire chains on the optional 265/45ZR20 Sport tires and
wheels of your vehicle. The use of any type of tire chain on these tires
may damage your vehicle.
•For tire pressures, see the placard located on the B-pillar inside the
driver’s door.
•Always maintain your tire pressures according to the tire information
placard on the driver’s door jamb, using an accurate gauge.
If your vehicle is equipped with P265/45ZR20 tires, they are low-profile
tires. These tires and wheels are designed to give your vehicle a sport
appearance. With low-profile tires, you may notice an increase in road
noise and faster tire wear, depending on road conditions and driving
styles. Due to their design, low-profile tires and wheels are more prone
to road damage from potholes, rough or unpaved roads, car wash rails
and curb contact than standard tires and wheels.
Note:Your vehicle’s warranty does not cover these types of damage.
Tires should always be kept at the correct inflation pressures and extra
caution should be taken when operating on rough roads to avoid impacts
that could cause wheel and tire damage.
Information About Uniform Tire Quality Grading
Tire Quality Grades apply to new
pneumatic passenger car tires. The Tire
Quality Grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
•Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by standards that the United
States Department of Transportation has set.

•Sidewall of the tire:Area between the bead area and the tread.
•Tread area of the tire:Area of the perimeter of the tire that
contacts the road when mounted on the vehicle.
•Rim:The metal support (wheel) for a tire or a tire and tube assembly
upon which the tire beads are seated.
INFORMATION CONTAINED ON THE TIRE SIDEWALL
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.
Information on P Type Tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
A.P:Indicates a tire, designated by the Tire and Rim Association, that
may be used for service on cars, sport utility vehicles, minivans and light
trucks.
Note:If your tire size does not begin with a letter, this may mean it is
designated by either the European Tire and Rim Technical Organization
or the Japan Tire Manufacturing Association.
B.215:Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
C.65:Indicates the aspect ratio which gives the tire’s ratio of height to
width.

Information on T Type Tires
T type tires have some additional
information beyond those of P type
tires. These differences are
described below.
T145/80D16 is an example of a tire
size.
Note:The temporary tire size for
your vehicle may be different from
this example. Tire Quality Grades
do not apply to this type of tire.
A.T:Indicates a type of tire, designated by the Tire and Rim
Association, that is intended for temporary service on cars, sport-utility
vehicles, minivans and light trucks.
B.145:Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
C.80:Indicates the aspect ratio, which gives the tire’s ratio of height to
width. Numbers of 70 or lower indicate a short sidewall.
D.D:Indicates a diagonal type tire.R:Indicates a radial type tire.
E.16:Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
Location of the Tire Label
You will find a Tire Label containing tire inflation pressure by tire size
and other important information located on the B-Pillar or the edge of
the driver’s door. See the payload description and graphic in theLoad
Carryingchapter.
