Hitch
Trailer hitch assemblies have different weight capacities established by the hitch
manufacturer. Even though the vehicle ma y be physically capable of towing a
higher weight, the operator must determine the maximum weight rating of the par-
ticular hitch assembly and never exceed the maximum weight ra ting specified for
the trailer-hitch. Exceeding the maximum we ight rating set by the trailer-hitch man-
ufacturer can cause an accident resulting in death or serious personal injuries.■
When towing a trailer
Lexus recommends trailers with brakes that conform to any applicable federal and
state/provincial regulations. ●
If the gross trailer weight exceeds unbr aked TWR, trailer brakes are required.
Lexus recommends trailers with brakes that conform to all applicable federal and

Never tap into your vehicle’s hydraulic system, as this will lower the vehicle’s
braking effectiveness. ●
Never tow a trailer without using a safety chain securely attached to both the
trailer and the vehicle. If damage occurs to the coupling unit or hitch ball, there is
danger of the trailer wandering into another lane.
