The body sealant and under-floor protection must be removed from all the body mounting points of the trailer hitch. The mounting points should then be cleaned with a commercially available cleaning agent. Apply anticorrosion paint to bare-metal areas of the body.
Trailer hitches are approved safety-related parts. They must be installed on vehicles by a specialist. Trailer couplings which have been damaged in an accident, by bottoming or by an impact from behind must be replaced; subsequent modifications such as bending, machining, welding, etc. are not permitted.
The coupling ball must have a minimum diameter of 49 mm at all points, measured using a caliper gauge. If this is not the case, the coupling ball must be replaced by a new one. The ball must be greased before use to reduce wear.
The micro-encapsulated locking bolts and self-locking nuts may only be used once. If parts of the trailer hitch are removed, new micro-encapsulated bolts and self-locking nuts must be used when reinstalling these parts.
On trailers with an anti-swerve device it is not necessary to grease the ball (refer to trailer instructions). Advise the customer accordingly.
Advise the customer to read the "Trailer coupling" and "Towing a trailer" sections in the vehicle owner's manual.
