2019 NISSAN FRONTIER PRO-4X height

To increase your confidence in the seat
belts, check the operation as follows:∙ Grasp the shoulder belt and pull for- ward quickly. The retractor should lock
and restrict further belt movement.
If the retractor does not lock during this
check, get the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service or to learn more about seat belt
operation.
Shoulder belt height adjustment
(front seats)
The shoulder belt anchor height should be
adjusted to the position best for you. For
additional information, refer to “Precau-
tions on seat belt usage” in this section. To
adjust, pull out the adjustment button
1
and move the shoulder belt anchor to the
desired position
2, so the belt passes over
the center of the shoulder. The belt should
be away from your face and neck, but not
falling off your shoulder. Release the ad-
justment button to lock the shoulder belt
anchor into position.

WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no
higher than the measured reference
height when the trailer is attached. If
the rear bumper is higher than the mea-
sured reference height when loaded,
the vehicle may handle unpredictably
which could cause a loss of vehicle con-
trol and cause serious personal injury or
property damage.
Sway control device
Sudden maneuvers, wind gusts, and buf-
feting caused by other vehicles can affect
trailer handling. Sway control devices may
be used to help control these affects. If you
choose to use one, contact a reputable
trailer hitch supplier to make sure the sway
control device will work with the vehicle,
hitch, trailer and the trailer’s brake system.
Follow the instructions provided by the
manufacturer for installing and using the
sway control device.
