The maximum weight of a trailer able to be towed by your vehicle will be outlined in the vehicle’s owner’s manual. This will specify weights for trailers with brakes and without brakes. These weight limits take into account the effect of the trailer on the vehicle’s overall safety performance and durability. If the trailer is within the vehicle’s specified towing weight limits and the vehicle is properly maintained, your vehicle will be able to handle the loads of a trailer that is within the appropriate limits. Of course, extra care is always required when towing, such as using the appropriate gearing when descending and ascending hills.
Most modern vehicles are designed to be driven normally from a cold start-up. This doesn’t mean accelerating hard or towing immediately after a cold start, just regular driving. This will help the engine reach normal operating temperature in reasonable time.
However, older vehicles such as those with carburettors, may need to be warmed up, particularly in cold weather. Generally speaking, idling a modern car for several minutes before driving it will just burn more fuel and cause more exhaust emissions.
