Trailer Lights; Trailer Brakes - Mazda CX-9 2016 Owner's Manual

Before Driving
Towing
Safety Chains
Safety chains must be used as a precautionary measure should the trailer become
unintentionally unhitched. They should cross under the trailer tongue and attach to the hitch.
Leave enough slack to allow full turns. Consult literature published by your trailer or hitch
manufacturer for more details.
WARNING
Make sure the safety chain is securely attached to both the trailer and the vehicle prior
to departure:
Towing a trailer without using a safety chain securely attached to both the trailer and the
vehicle is dangerous. If damage occurs to the coupling unit or hitch ball, the trailer could
wander into another lane and cause a collision.

Trailer Lights

Trailer lights must comply with all federal, state, and local regulations. Equip your trailer as
required before towing it day or night.
CAUTION
Do not connect a trailer lighting system directly to the lighting system of your Mazda. This
may damage your vehicle's electrical system and lighting systems. Have a recreational
vehicle dealer or trailer rental agency connect the system, and inspect the brake lights
and turn signals yourself before each trip.

Trailer Brakes

If the total trailer weight exceeds 450 kg (1,000 lb), trailer brakes are required. If your trailer
has brakes, make sure they comply with all federal, state, and local regulations.
WARNING
Do not connect a hydraulic trailer-brake system to your vehicle's brake system:
Connecting a hydraulic trailer-brake system directly to the vehicle brake system is
dangerous and will result in inadequate braking and possible injury.
