Trailer towing
Your vehicle is designed primarily as a passenger-and-load-car-
rying vehicle. Towing a trailer can have an adverse impact on
handling, performance, braking, durability, and fuel consump-
tion. For your safety and the safety of others, you must not ov er-
load your vehicle or trailer. You must also ensure that you are
using appropriate towing equipm ent, that the towing equipment
has been installed correctly a nd used properly, and that you
employ the requisi te driving habits.
Vehicle-trailer stability and braking performance are affected by
trailer stability, brake performance and setting, trailer brake s,
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 addi-
tional requirements such as a towing kit, etc.

axle weight. The gross axle
weight is the load placed on
each axle (front and rear).
■TWR (Trailer Weight Rating)
The maximum allowable gross

reduce the trailer weight rating so as not to exceed GCWR, GVWR and
