Trailer towing
Contact your Toyota dealer for further information about additi onal
requirements such as a towing kit, etc.
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 requisite driving habits. (P. 192)
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.

1744-1. Before driving
■GCWR (Gross Combination Weight Rating)
The maximum allowable gross
combination weight. The gross
combination weight is the sum
of the total vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) and the
weight of the trailer being towed
(including the cargo in the
trailer).
■GVWR (Gross Vehicle Weight Rating)
The maximum allowable gross
vehicle weight. The gross vehi-
cle weight is the total weight of
the vehicle. When towing a
trailer, it is the sum of the vehi-
cle weight (including the occu-
pants, cargo and any optional
equipment installed on the vehi-
cle) and the tongue weight.
■GAWR (Gross Axle Weight Rating)
The maximum allowable gross
axle weight. The gross axle
weight is the load placed on
each axle (front and rear).

Driving
■TWR (Trailer Weight Rating)
The maximum allowable gross
trailer weight. The gross trailer
weight is the sum of the trailer
weight and the weight of the
cargo in the trailer.
TWR is calculated assuming
base vehicle with one driver,
one front passenger, towing
package (if available), hitch and
hitch systems (if required).
Additional optional equipment, passengers and cargo in the vehicle will
reduce the trailer weight rating so as not to exceed GCWR, GVWR and
GAWR.
If the gross trailer weight exceeds 3000 lb. (1360 kg), it is r ecommended
to use a trailer with 2 or more axles.
■
Unbraked TWR (Unbraked Trailer Weight Rating)
The trailer weight rating for tow-
ing a trailer without a trailer ser-
vice brake system.
■Tongue Weight
The load placed on the trailer
hitch ball. ( P. 183)
(With brakes)
(Without brakes)

1764-1. Before driving
■Kingpin Weight
The load placed on the 5th
wheel mount or the gooseneck
ball. (P. 1 8 4 )
● The gross trailer weight must never exceed the TWR described in
the table. ( P. 1 7 7 )
● The gross combination weight must never exceed the GCWR
described in the table. ( P. 1 7 7 )
● The gross vehicle weight must
never exceed the GVWR indi-
cated on the Certification Label.
● The gross axle weight on each
axle must never exceed the
GAWR indicated on the Certifi-
cation Label.
● If the gross trailer weight is over the unbraked TWR, trailer s ervice
brakes are required.
● If the gross trailer weight is over 2000 lb. (907 kg), a sway c ontrol
device with sufficient capacity is required.
● If the gross trailer weight is over 5000 lb. (2268 kg), a weigh t distrib-
