SWAY CONTROL DEVICE
Sudden maneuvers, wind gusts, and buffeting caused by other vehicles can affect trailer handling.
Sway control devices may help control these effects. 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. A sway control device is recommended for all towing above 2,000 lb
(907 kg). Follow the instructions provided by the manufacturer for installing and using the sway
control device.
BREAKAWAY SWITCH
On a trailer with electric brakes, a breakaway switch can automatically activate the trailer brake
system if the trailer becomes separated from the tow vehicle. Should the trailer become detached,
a breakaway switch may help prevent the trailer from wandering into another lane.
A breakaway switch relies on the power of a trailer battery, so make sure it is not discharged. Never
use the breakaway switch to “park” the trailer on a grade. The battery would eventually discharge
and release the brake, allowing the trailer to roll.
Be sure to leave enough slack in the tether on the breakaway switch to turn corners without binding.
If you do not, the electric trailer brakes will lock-up and not release. See your trailer manufacturer
for proper installation of a breakaway switch that is compatible with your trailer braking system.
TRAILER LIGHTS
Trailer lights should comply with all applicable federal, state, and local regulations, and should be
in proper working order at all times. A trailer’s taillights, stoplights, and turn signal lights must be
wired into the towing vehicle’s electrical system.*
Most trailers operate on a four-wire system in which the stoplights and turn signal lights utilize the
same wire. Most all Infiniti vehicles have separate wires for the stoplights and turn signal lights,
therefore a device called a “converter” is needed.** Specifically, a “powered converter” must be
used, as a converter of this type creates only minimal additional electrical demand (draw) on the
vehicle lighting circuits, which helps to ensure protection for the vehicle’s sensitive electronics.
Always check for correct operation of the taillights, stoplights, and turn signal lights every time you
connect a trailer for towing. Never replace vehicle fuses with fuses of a higher amperage rating than
the original.
*Vehicles equipped with LED taillights require that wiring be connected at a specific location. For assistance in
hooking up trailer lights, contact your Infiniti retailer or a professional supplier of towing equipment.
**QX56 and JX35 vehicles are pre-wired for trailer lighting and do not require a converter.
