202 STARTING AND OPERATING
(Continued)
(Continued)
Trailer Memory
The trailer steering system will automatically retain
the
calibration of the previous five trailers
connected, so recalibration will not be necessary
when hooking up. The next time the vehicle is
started, place the vehicle in DRIVE and drive a
short distance. The TRSC system can then be
activated.
NOTE:
Trailers may look different during day and night
condi
tions. In such cases, the trailer may need to
recalibrate.
Some trailers (such as boat trailers) will need to
reca
librate while loaded and unloaded.
NOTE:
The system may not detect a trailer in low light
conditions. In sunny conditions, the perfor-
mance may be degraded as shadows pass over
t
he
trailer.
The driver is always responsible for safe opera-
tion 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
Serv
icing section for the proper maintenance
intervals
Ú page 363. 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.
T
h
e
engine, axle or other parts could be
damaged.
Then, during the first 500 miles (805 km) that
a tr ailer is towed, do not drive over 50 mph
(80
k
m/h) and do not make starts at full
t
h
r
ot
tle. 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 collision.
When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading
can cause a loss of control, poor performance
or damage to brakes, axle, engine, transmis
-
sion, steering, suspension, chassis structure
or ti
res.
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.
Vehicles with trailers should not be parked on
a grade. When parking, apply the parking
brake on the tow vehicle. Put the tow vehicle
transmission in PARK. For four-wheel drive
vehicles, make sure the transfer case is not in
NEUTRAL. Always, block or "chock" the trailer
wheels.
GCWR must not be exceeded.
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded:
GVWR
GTW
