Jeep Grand Cherokee 2013 Operating Information Manual page 283

WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the
vehicle and have an accident.
Trailer Tongue Weight (TW)
The TW is the downward force exerted on the
hitch ball by the trailer. In most cases it should
not be more than 5% of the trailer load. You
must consider this as part of the load on your
vehicle.
WARNING!
An improperly adjusted hitch system may
reduce handling, stability and braking perfor-
mance and could result in an accident. Con-
sult with your hitch and trailer manufacturer
or a reputable trailer/caravan dealer for ad-
ditional information.
Frontal Area
The frontal area is the maximum height multi-
plied by the maximum width of the front of a
trailer.
Breakaway Cable Attachment
European braking regulations for braked trailers
up to 7,700 lbs (3 500 kg), require trailers to be
fitted with either a secondary coupling or break-
away cable.
The recommended location for attaching the
normal trailer's breakaway cable is in the
stamped slot located on the sidewall of the hitch
receiver.
With Attachment Point
• For detachable tow bar pass the cable through
the attachment point and clip it back onto itself
or attach the clip directly to the designated
point.
