■Matching trailer ball height to trailer coupler height
■ Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 581)
● Trailer tires are inflated according to the trailer manufacturer’s recom-
mendation.
● All trailer lights work as required by law.
● All lights work each time you connect them.
● The trailer ball is set at the proper height for the coupler on the trai\
ler.
● The vehicle remains level when a loaded or unloaded trailer is hitched.
Do not drive if the vehicle is not level, and check for improper tongue
weight, overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
No matter which class of tow hitch
applies, for a more safe trailer hookup,
the trailer ball setup must be the proper
height for the coupler on the trailer.

CAUTION
■Hitch
Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. 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 assembly 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
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
●If the gross trailer weight exceeds unbraked TWR, trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’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.
