of the trailer lights and assure their proper functioning, a
heavy duty turn signal flasher can be installed as a
separate equipment item by your dealer.
WARNING!
The direct connection of hydraulic brake lines from
vehicle brake system to trailer system is not accept-
able. The extra load may cause brake failure and you
may be injured.
Heavy trailer towing also may require breakaway electric
trailer brakes, anti-sway devices or equalizing hitches for
safe operation. Such devices are commonly required by
state law.
For all trailer tow or heavy-duty applications it is
strongly recommended that the factory fill rear axle
lubricant be replaced with an SAE 75W-140 synthetic
gear lubricant. Mopar Synthetic Gear Lubricant is of
this type.
