140 STARTING AND OPERATING
Check for signs of tire wear or visible tire

damage before towing a trailer.
Replacing tires with a higher load carrying

capacity will not increase the vehicle's GVWR
and GAWR limits.

Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system

or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake

controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Trailer brakes are recommended for trailers

over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
WARNING!
Do not connect trailer brakes to your vehicle's

hydraulic brake lines. It can overload your
brake system and cause it to fail. You might
not have brakes when you need them and
could have an accident.
Towing any trailer will increase your stopping

distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could
result in an accident.
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do
this could lead to accelerated brake lining wear,
higher brake pedal effort, and longer stopping
distances.
Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory approved
trailer harness and connector.

Disconnect the trailer wiring connector from the

vehicle (or any other device plugged into the
vehicle's electrical connectors) before
launching a boat into water.
