TOWING GLOSSARY
BALL MOUNT A bar that holds the hitch ball and is inserted into the hitch receiver.
BRE AK AWAY SWI TCH A safety device using a trailer battery that automatically applies the trailer’s
brakes if it should accidentally become separated from the tow vehicle.
1. Maximum Trailer Weight values are calculated assuming a base
vehicle with driver and any options required, to achieve the
rating. Additional passengers, cargo and/or optional equipment
will add weight to the vehicle and reduce your vehicle’s
maximum towing capacity and trailer tongue load.
2. In general, a weight -distributing hitch system (Class IV) should be
used when towing over 5,000 lbs.
3. Most states require a separate braking system on trailers with a
loaded weight above a specific amount. Check local ordinances.
7- pin connector trailer wire harnesses are required for use with
trailer brakes (available separately).
