Your vehicle is designed primarily as a passenger-and- load-carrying vehicle.
Towing a trailer can have an adverse impact on handling, performance, braking, durability, and fuel consumption.
For your safety and the safety of others, you must not overload your vehicle or trailer. You must also ensure that you are using appropriate towing equipment, that the towing equipment has been installed correctly and used properly, and that you employ the requisite driving habits.
Vehicle-trailer stability and braking performance are affected by trailer stability, brake performance and setting, trailer brakes, the hitch and hitch systems (if equipped).
To tow a trailer safely, use extreme care and drive the vehicle in accordance with your trailer's characteristics and operating conditions.
Toyota warranties do not apply to damage or malfunction caused by towing a trailer for commercial purposes.
Contact your Toyota dealer for further information about additional requirements such as a towing kit, etc.
â– Before towing
Check that the following conditions are met:
Do not drive if the trailer is not level, and check for improper tongue weight, overloading, worn suspension, or other possible causes.
â– When towing a trailer
Disable the following systems, as the systems may not operate properly.
WARNING
â– Trailer towing precautions
To tow a trailer safely, use extreme care and drive the vehicle in accordance with the trailer's characteristics and operating conditions.
Failure to do so could cause an accident resulting in death or serious injury. Vehicle stability and braking performance are affected by trailer stability, brake setting and performance, and the hitch. Your vehicle will handle differently when towing a trailer.
â– To avoid accident or injury
If you experience a vehicle-trailer instability from reducing a certain speed, slow down and make sure you keep your vehicle speed under the speed of which you experience the instability.
Before descending steep or long downhill grades, slow down and downshift. Do not make sudden downshifts when descending steep or long downhill grades. Avoid holding the brake pedal down too long or applying the brakes too frequently.
This could cause the brakes to overheat and result in reduced braking efficiency.
â– When towing a trailer
Toyota recommends trailers with brakes that conform to any applicable federal and state/provincial regulations.
If damage occurs to the coupling unit or hitch ball, there is danger of the trailer wandering into another lane.
