Lincoln Navigator (2019 year). Manual - part 17

Action

Cause

Do not use the system in these conditions because it may not detect
any vehicles ahead.

Water, snow or ice on the surface of the road may interfere with the
radar signals.

Wait a short time or switch to normal cruise control.

You are in a desert or remote area with no other vehicles and no
roadside objects.

Due to the nature of radar technology, it is possible to get a blockage warning with no actual block. A false blocked condition either self
clears, or clears after you restart your vehicle.

Switching to Normal Cruise Control

WARNING: Normal cruise control will

not brake when your vehicle is
approaching slower vehicles. Always be
aware of which mode you have selected
and apply the brakes when necessary.

E71340

The cruise control indicator light
replaces the adaptive cruise
control indicator light if you select

normal cruise control. The gap setting does
not display, and the system does not respond
to lead vehicles. Automatic braking remains
active to maintain set speed.

You can change from adaptive cruise control
to normal cruise control through the
information display.  See General
Information (page 120).

not choose or add a new trailer.

Note: The warning message may not appear
until your vehicle speed reaches 22 mph
(35 km/h).

If you select a trailer in the information
display before connecting a trailer to your
vehicle, the system loads the configuration
for the selected trailer. When a trailer is
connected, a warning message appears.

Note: A second warning message may
appear stating that the Cross Traffic Alert
system has turned off. The Blind Spot
Information System with Trailer Tow
continues to function normally in this
situation.

Note: The system remembers the last
selected trailer set up when you start your
vehicle.

Trailer Considerations

The system is designed to work with a trailer
with a front width of 8.5 ft (2.6 m) or less, and
a total length from the trailer hitch ball to the
rear of the trailer of 33 ft (10.1 m) or less.

Some trailers may cause a slight change in
system performance:
•

Large box trailers may cause false alerts
to occur when driving next to
infrastructures or near parked cars. A
false alert may also occur while making
a 90-degree turn.

•

Trailers that have a width greater than
8.5 ft (2.6 m) at the front and have a total
length greater than 20 ft (6 m) may cause
delayed alerts when a vehicle is passing
at high speed.

274

Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201808, First-Printing

Driving Aids

•

Box trailers that have a width greater than
8.5 ft (2.6 m) at the front may cause early
alerts when you pass a vehicle.

•

Clam shell or V-Nose box trailers with a
width greater than 8.5 ft (2.6 m) at the
front may cause delayed alerts when a
vehicle traveling the same speed as your
