When driving
Trailer towing
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, yo u must not overload your vehicle
or trailer. You must also ensure that you are using appropriate tow-
ing equipment, that the towing eq uipment has been installed cor-
rectly and used properly, and that you employ the requisite driving
habits.
Vehicle-trailer stability and braki ng 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 condi-
tions.
Toyota warranties do not apply to damage or malfunction caused by
towing a trailer for commercial purposes.
Contact your Toyota dealer for fu rther information about additional
requirements such as towing kits, etc.

Towing related terms■ 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 Vehi cle Weight Rating)
The maximum allowable gross
vehicle weight. The gross vehicle
weight is the total weight of the
vehicle. When towing a trailer, it
is the sum of the vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) and the
tongue weight.

When driving
■
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).
■ 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 sys-
tems (if required).
Additional optional equipment,
passengers and cargo in the vehi-
cle 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 recom-
mended to use a trailer with 2 or
more axles.

Rear GAWR
(With brakes)

226 2-5. Driving information
■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. 232)
(Without brakes)
