•Bumper centreline –where the centreline of the bumper needs to be determined, the installer
must assess centre point by measurement of bumper width or determining two symmetrical
reference points to give centreline.
•Bumper edge –To assist with accurate bumper cut measurement, reference to the start of the
bumper edge is now being commonly used.
oMeasure from bottom edge along bumper and around corner to the 70 mm point
(Figure 1).
oDo not measure from visible bumper front of corner, upwards (Figure 2).

•For any required drilling during installation, ensure that the area is clear of fuel, electrical & other components that may be
damaged.
•All holes drilled into the body panels shall have all burrs & swarf removed then coated with a suitable rust preventative paint.
8. Bolts/Fasteners
•Ensure that all hardware is fastened to correct torque as specified in this fitting instruction.
•All fasteners supplied with this product are used to achieve a specified clamp loading. If replacement is required ensure that
fasteners of the same grade and class are used.

THANK YOU FOR PURCHASING HAYMAN REESE.
WITH CORRECT MAINTENANCE AND CARE THIS PRODUCT WILL PROVIDE A
LIFETIME OF TROUBLE-FREE OPERATION.
TOWBAR MAINTENANCE AND CARE:
1.
Hayman Reese recommend that the towbar LUG or TBM (tow ball Mount) Pull Pin and R-clip are removed
and stored when not in use. Removal of LUG or TBM (tow ball mount) is advisable when not in use to
assist with any of the following.
•Ensure rear number plate is not obscured.
•Allow maximum available departure angle and prevent any potential interference.
•Prevent possible interference with vehicles reverse sensors or camera detecting a tow ball mount
as an obstruction during reversing.
•Removes towball mount as an obstruction for when moving around the rear of the vehicle.
2.
Hayman Reese recommends routine inspection of your towbar to ensure trouble free towing.
•Bolt security and tension should be regularly inspected and checked for correct tension. Replace
any worn or defective parts with suitable grade & class fasteners. Inspection should be requested
to coincide with vehicle major services.
3.
It is the owner’s responsibility to ensure towing and down ball weight capacities of the towing vehicle are
not exceeded.
•Towing and down ball weights allowable may differ according to model variations. Please refer to
owner’s manual or vehicle dealer to confirm exact rating for your vehicle model variant.
•It is not uncommon for the vehicle tow rating to differ from the towbar rating. When this occurs,
the lesser rating must be adhered to.
•For vehicles fitted with enhanced vehicle functions that may be altered/changed when towing i.e
Trailer sway mitigation, blind spot detection, adaptive cruise control etc. Please consult owner’s
manual to understand changes enabled when towing and after towing.

Appendix
WARNING: This vehicle requires a system setting to ensure the trailer wiring and control module
are correctly recognised. This process (referred to as ‘coding’) must be carried out to enable
correct vehicle functionality when trailer is connected. Towing features enabled by correct control
module and coding support OE functionality as set by OE manufacturer. Please read the vehicles
owner’s manual for proper operation and understanding.
Coding can be carried out using the Hayman Reese SmartCODE (HRSC) using the following steps.
Note, if HRSC is unavailable, vehicle coding can be carried out by OE manufacturer as needed.
Before you start:
•Ensure the HRSC software is up to date using the HAYMAN REESE SMARTCODE PC APP.
•Ensure the vehicle battery is fully charged
•Use of a battery support unit (BSU) is advised during the coding process.
•Ensure towbar, wiring loom and ECU are correctly installed as per Hayman Reese fitting
instructions.
1. Locate the OBD2 port under the drivers footwell on the right-hand side and plug in the HRSC.
2. Close all doors and turn the ignition on
3. Follow the directions on the screen of the HRSC
4. Once the vehicle has been coded successfully proceed to the “clear codes” tab
5. Remove disconnect HRSC from OBD2 port.
6. Check the dash to make sure there are no warning faults.
7. Check the operation of trailer lights and ensure the Reverse Park Assist (RPA) is disabled and
‘trailer on’ icon is active where available.
For technical support and further information on Hayman Reese SmartCODE tool and coding process
