Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available power-
type module/converter must be used to
provide power for all trailer lighting. This
unit uses the vehicle battery as a direct
power source for all trailer lights while
using the vehicle tail light, stoplight and
turn signal circuits as a signal source. The
module/converter must draw no more that
15 milliamps from the stop and tail lamp
circuits. Using a module/converter that
exceeds these power requirements may
damage the vehicle’s electrical system.
See a reputable trailer dealer to obtain the
proper equipment and to have it installed.
Trailer lights should comply with federal and/or
local regulations. For assistance in hooking up
trailer lights, contact a NISSAN dealer or repu-
table trailer dealer. Vehicles equipped with the
optional trailer tow package are equipped with a
7-pin trailer harness connector. A flat 4–pin har-
ness is available from your dealer for vehicles
without a tow package. If your trailer is equipped
with a flat 4-pin connector, an adapter will be
needed to connect the trailer lights to the vehicle.
Adapters are available at auto parts stores and
hitch retailers.
Trailer brakes
If your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed.
Vehicles equipped with a 7–pin trailer harness
connector are pre-wired for a trailer brake con-
troller. See a NISSAN dealer for a trailer brake
adapter harness.
WARNING
Never connect a trailer brake system di-
rectly to the vehicle brake system.
When towing a trailer load of 3,500 lbs.
(1587 kg) or more, trailers with a brake
system MUST be used. However, most states
require a separate braking system on trailers with
a loaded weight above a specific amount. Make
sure the trailer meets the local regulations and
the regulations where you plan to tow.
Several types of braking systems are available.
Surge Brakes -The surge brake actuator is
mounted on the trailer tongue with a hydraulic line
running to each trailer wheel. Surge brakes are
activated by the trailer pushing against the hitch
ball when the tow vehicle is braking. Hydraulic
surge brakes are common on rental trailers and
some boat trailers. In this type of system, there is
no hydraulic or electric connection for brake op-
eration between the tow vehicle and the trailer.
Electric Trailer Brakes -Electric braking sys-
tems are activated by an electronic signal sent
from a trailer brake controller (special brake-
sensing module). If electric trailer brakes are
used, see
ЉElectric trailer brake controllerЉ in this
section.
Have a professional supplier of towing equip-
ment make sure the trailer brakes are properly
installed and demonstrate proper brake function
testing.
Electric trailer brake controller
Trailers equipped with electric brakes may re-
quire the installation of an aftermarket trailer
brake controller.
A Genuine NISSAN jumper harness is available
that is specifically designed to be used when
installing an aftermarket brake controller.
Install the aftermarket electric trailer brake con-
troller according to the manufacturer’s instruc-
tions.
