hands from the steering wheel.
There is also a holdover state where if during an
active trailer steering maneuver, the driver
shifts to NEURAL or DRIVE to straighten the
trailer, the driver may shift back to REVERSE
and not need to reactivate the feature. However
the feature will cancel after 10 seconds or when
the vehicle speed reaches 8 mph (12 km/h). Instrument Cluster Messages:
“Drive forward to calibrate trailer” will display

vehicle is at standstill while the button is
pushed.
“Calibrating trailer” will display when the
trailer is not calibrated and the vehicle is
moving while the button is pushed.
“To activate trailer steering shift to P” will
display when the trailer is calibrated success
-
fully and the vehicle is not in PARK.
“Trailer Steering ready, shift to reverse” will
display when the button is pushed, trailer is
calibrated and the vehicle is in PARK.
“Trailer steering active” will display after the
driver shifts to REVERSE and indicates the
feature is active.
“Trailer Steering Unavailable” will display if
there is a fault in the system preventing acti -
vation, the driver’s door is open, the driver’s
seat belt is unbuckled, or the tailgate is open. Other reasons the feature may cancel:
The driver overrides steering by placing
hands on the steering wheel.
Trailer tracking is lost.
If the trailer angle becomes excessive, the
brakes apply bringing the vehicle to a stop
and then applying the parking brake.
Trailer steering button is pushed while active.
Vehicle speed goes over 8 mph (12 km/h).
Driver door is open and seat belt is
unbuckled.
Transmission shifted to PARK.
Trailer Memory
The trailer steering system can remember up to
five trailers, so recalibration will not be
necessary.
To store a trailer to memory, calibrate the trailer
and then allow the vehicle to be off for a period
of time. The next time the vehicle is started,
place the vehicle in DRIVE and drive a short
distance. The trailer system can then be
activated.

STARTING AND OPERATING221
(Continued)
NOTE:
Trailers may look different during day and night
conditions. In such cases, the trailer may need
to recalibrate.
Some trailers (such as boat trailers) will need to
recalibrate while loaded and unloaded.
NOTE:
The system may not detect a trailer in low
light conditions. In sunny conditions, the
performance may be degraded as shadows
pass over the trailer.
The driver is always responsible for safe oper -
ation of truck and trailer.
The driver is always in control of the truck as
well as the trailer and is responsible for
controlling the throttle and brakes.
The system may not function when the
camera lens is blocked, blurred (covered with
water, snow, ice, dirt, etc) and will not work
unless the tailgate is upright and fully
latched.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended.
Perform the maintenance listed in the
Scheduled Servicing section for the proper
maintenance intervals Ú page 395. When
towing a trailer, never exceed the GAWR or
GCWR ratings.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven. The engine, axle or other parts could
be damaged.
Then, during the first 500 miles (805 km) that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could
lose control of your vehicle and have a colli -
sion.
When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over -
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspension,
chassis structure or tires.
Safety chains must always be used
between your vehicle and trailer. Always
connect the chains to the hook retainers of
the vehicle hitch. Cross the chains under
the trailer tongue and allow enough slack
for turning corners.
