Vehicle Operation

Electric Brakes
The electric brakes are designed to work with the tow vehicle brakes. To maintain proper braking performance, both the RV and tow vehicle brakes must be used together. Separate use of the braking systems will cause accelerated wear and damage. When your RV is new, it is impossible to adjust the brake shoes precisely. It takes approximately 1,000 miles and/or 50 medium to heavy stops to “burnish” fit or “seat” the shoes to the brake drum. After the initial break-in period, your brake shoes must be adjusted accurately for the best performance and increased durability.

Braking system components include:

1. Tow vehicle battery
2. Brake controller
3. Wire harness/connector plug
4. Trailer battery
5. Breakaway switch

The tow vehicle battery is the primary source of power for your RV’s electric brake operation. To ensure available power when needed, keep your tow vehicle battery and charging system working properly.

Brake Controller (customer supplied)
The brake controller should be installed in the tow vehicle to work in conjunction with the RV electric brakes. Consult with your dealer or the brake controller OEM to decide what is right for your towing combination.

Travel Trailer Breakaway Switch
The breakaway switch is a crucial part of the RV braking system. Located on the travel trailer A-frame (or beside the fifth wheel pinbox), this switch will apply the trailer brakes if the trailer becomes detached from the tow vehicle. Attach the breakaway switch lanyard to a permanent part of the tow vehicle (on a travel trailer do not attach it to the hitch ball or similar removable parts) when hitching the trailer. If the RV becomes detached from the tow vehicle, the pull pin will be pulled from the switch. This automatically causes the switch to “close” and activates the RV brakes. A battery (customer supplied) must be installed to activate the breakaway switch.

CAUTION:
NEVER use the breakaway switch and trailer brake system as a parking brake. Doing so would create a high amp draw on the battery and converter. This can cause damage to wiring, connectors and the breakaway switch.

Hydraulic Brakes (if so equipped)
Your RV may be equipped with hydraulic surge brakes that operate automatically as the tow vehicle’s brakes are applied. When speed is decreased and brakes are applied, the weight of the trailer moving forward creates a reaction, which causes the brake fluid inside the wheel cylinder to activate the brake shoes against the drum. As a result of this design, backing the RV uphill may activate the surge brake system making it difficult to continue in reverse.

To aid in backing up the RV:

1. Prior to backing up a slope or through soft ground, pull the recreation vehicle forward slightly to assure that the actuator socket is in the forward position.
2. Move the lever on the side of the actuator downward from the “towing position” along the curved slot in the actuator frame to the “backup position.” The slot has a notch at the bottom of its travel. Push the lever down to engage the locking notch.
3. The RV will now be back up. This lever will slide into the correct position when pulling forward.

It is extremely important to keep the master cylinder full at all times. An empty cylinder invites moisture.

Disc Brakes (if so equipped)
If your RV is equipped with disc brakes, see the manufacturer’s owner’s manual for detailed safety and maintenance information.

WARNING:
If you do not have a Jayco factory-installed hitch receiver, towing items behind your Jayco RV, or overloading the rear, will void the warranty and may result in: damage to the RV or add-on items, towing difficulties, property damage and/or personal injury.

NOTE: IF YOU DO NOT HAVE A JAYCO FACTORY-INSTALLED HITCH RECEIVER, DO NOT TOW ANYTHING BEHIND YOUR RV. THE RV FRAME AND BUMPER ARE NOT DESIGNED FOR TOWING.
A hitch equipped for trailer towing will have tabs to hang the safety chains and there will be a bracket for the trailer wiring plug. There should also be a label on the hitch stating maximum towing capacity.

Entrance Door Step(s)
Make sure your entrance step is fully extended before exiting the vehicle, and retracted prior to towing.

Lubricating the step mechanism
Carefully clean the area around the pivot points (the rivets involved in the motion of the mechanism). Lubricate these pivot points with an automotive-grade, non-staining lubricant every 30 to 60 days.
Wipe any excess lubricant off of the step and then clean the entire step after lubricating.

Step Light
Your RV may be equipped with a switch located on the skirt (in front of the steps) which operates a light located under the step assembly.

CAUTION:

1. Do not try to lift the steps while the door is closed. This may cause damage to the steps and the door.
2. When returning steps to the stored position: adjustable feet may have to be retracted to fit inside the door opening.
3. Make sure people and pets are clear of the area when rotating the steps down to the ground or raising them for storage.

WARNING:

1. Maximum Weight Capacity 500 lbs.
2. Maintain hold of the steps until lowered all the way to the ground.
3. Prior to use, the legs must be adjusted properly to ensure the step is level.
4. Ensure that both latches are engaged when the steps are stored.
5. Failure to follow these instructions could lead to damage to the unit or serious injury.

Your RV may be equipped with one (or two) sets of the Stowable Entrance Steps. With these steps, there is no accessible steps mounted on the exterior of the RV. They are a one piece solid (3 or 4 step) assembly that latches inside the doorway of the RV. The steps rotate down and out of the doorway, and include two adjustable feet to provide stability while parked on rough terrain. The step assembly weighs 17 lbs. and has a weight capacity of 500 lbs.

NOTE: Certain models may have dual gas struts built into the step mechanism make the steps very easy to raise and lower in place.
