WARNING
Hitch
■
Trailer hitch assemblies have different weight capacities established by the hitch manu-
facturer. Even though the vehicle may be physically capable of towing a higher weight,
the operator must determine the maximum weight rating of the particular hitch assem-
bly and never exceed the maximum weight rating specified for the trailer-hitch.
Exceeding the maximum weight rating set by the trailer-hitch manufacturer 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 unbraked TWR, trailer brakes are required. Lexus
●
recommends trailers with brakes that conform to all applicable federal and state/pro-
vincial regulations.
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.
