Contact your Toyota dealer for further information about additional
requirements such as a towing kit, etc.
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 safe ty of others, you must not over-
load your vehicle or trailer. You must also ensure that you are
using appropriate towing equipmen t, that the towing equipment
has been installed correctly an d 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 appl y to damage or malfunction
caused by towing a trailer for commercial purposes.

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 Vehicl
e 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).
■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 recommended
to use a trailer with 2 or more axles.

●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 weight /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 sc ales found at a highway weigh-
ing station, building supply company, trucking company, junk
yard, etc.

Trailer hitch assemblies have different weight capacities. Toyota rec-
ommends the use of Toyota hitch/bracket 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 subs tances into the vehicle.
When removing the hitch cover,
contact your Toyota dealer.

Your vehicle will handle differently when towing a trailer. Help to avoid
an accident, death or serious injury, keep the following in mind when
towing:
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted to wing speed limit.
● Toyota recommends that the vehi cle-trailer speed limit is 65 mph
(104 km/h) on a flat, straight, dry road. Do not exceed this limit, the
posted towing speed limit or the spe ed limit for your trailer as set
forth in your trailer owner’s manual, whichever is lowest. Instability
of the towing vehicle-trailer combination (trailer sway) increases as
speed increases. Exceeding speed limits may cause loss of control.
● Before starting out, check the tr ailer lights, tires and the vehicle-
trailer connections. Recheck after driving a short distance.
● Practice turning, stopping and reversing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle-trailer combination.
● Reversing with a trailer attached is difficult and requires practice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left . Move your hand to the right to
move the trailer to right. (This is generally opposite to reversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to reduce the risk of an acci-
dent.
