ESSENTIAL TOWING CHECKS
Make sure the relevant safety warnings and cautions have been read and understood before towing a trailer. See TOWING SAFETY.
The following checks must be carried out before towing:
- Do not exceed the maximum permissible towing weights. See TOWING WEIGHTS.
- Load the trailer to achieve an even weight distribution between the axles when towing a trailer with more than one axle,
- Remember to include the weight of the trailer, plus the weight of the load, when calculating the laden weight of the trailer.
- If possible, spread the load of any cargo between the vehicle’s loadspace and the trailer. Loading more weight into the vehicle generally improves stability. Make sure not to exceed the vehicle’s weight limits.
- Check that the tire pressures are correct for the current loading condition of the vehicle.
- Make sure that a suitable safety chain is used and correctly connected. Refer to the trailer manufacturer’s guidelines. See TOW HITCH RECEIVER.
- Make sure that the tow ball is secure.
- Check the operation of all the trailer lights.
