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 equipment has been installed cor-
rectly and used properly, and that you employ the requisite driving
habits.
Vehicle-trailer stability and br aking performance are affected by
trailer stability, brake performan ce 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 Vehicle 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.

278 2-5. Driving information
■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.

Trailer Tongue Weight● A recommended tongue weight varies in accordance with the types
of trailers or towing as described below.
● To ensure the recommended values shown below, the trailer must
be loaded by referring to the following instructions.
• Tongue Weight
The gross trailer weight should be distributed so that the tongue
weight is 9% to 11%. (Tongue we ight /Gross trailer weight x 100
= 9% to 11%)
Gross trailer weight
Tongue weight
If using a weight distributing hitch when towing, return the front
axle to the same weight as before the trailer connection.
If front axle weight cannot be measured directly, measure the
front fender height above the front axle before connection.
Adjust weight distributing hitch torque until front fender is
returned to the same height as before connection.
The gross trailer weight, gross axle weight and tongue weight
can be measured with platform scales found at a highway
weighing station, building supply company, trucking company,
junk yard, etc.

Trailer hitch assemblies have different weight capacities. Toyota rec-
ommends the use of Toyota hitch/brac ket for your vehicle. For details,
contact your Toyota dealer.
● If you wish to install a trailer hitch, contact your Toyota dealer.
● Use only a hitch that conforms to the gross trailer weight require-
ment of your vehicle.
● Follow the directions supplied by the hitch manufacturer.
● Lubricate the hitch ball with a light coating of grease.
● Remove the trailer hitch whenever you are not towing a trailer.
After removing the hitch, seal any mounting hole in the vehicle
body to prevent entry of any substances into the vehicle.
