■ Before towing
Check that the following conditions are met:
● The vehicle’s tires are properly inflated.
● Trailer tires are inflated according to the trailer manufacturer’s recom-
mendation.
● All trailer lights work.
● All lights work each time you connect them.
● The trailer ball is set up at the proper height for the coupler on the t\
railer.
● 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
load, 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.
■ Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential and wheel bearing), Toyota
recommends that you do not tow a trailer until it has been driven for over 500
miles (800 km).
However, avoid full throttle acceleration.
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown.
