Trailer towing (with towing hitch)
Your vehicle is designed primarily as
a passenger-and-load-carrying vehicle.
Towing a trailer can have an adverse im pact on handling, performance, brak-
ing, durability, and fuel consumption. Fo r your safety and the safety of others,
you must not overload your vehicle or trailer. You must also ensure that you
are using appropriate towing equipment, that the towing equipment has been
installed correctly and used properly, and that you employ the requisite driv-
ing habits.
Vehicle-trailer stability and braking pe rformance are affected by trailer sta-
bility, brake performance and setting, tr ailer brakes, the hitch and hitch sys-
tems (if equipped).
To tow a trailer safely, use extreme ca re and drive the vehicle in accordance
with your trailer’s characteri stics and operating conditions.
Lexus warranties do not apply to damage or malfunction caused by towing a
trailer for commercial purposes.
Contact your Lexus dealer for further information about additional require-
ments such as towing kits, etc.

■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 avail-
able), 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 show
n 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 weig ht/Gross trailer weight  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 meas ured directly, measure the front fender
height above the front axle before co nnection. Adjust weight distributing
hitch torque until front fender is return ed to the same height as before con-
nection.
The gross trailer weight, gross axle weight and tongue weight can be mea-
sured with platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.

●Trailer tires are inflated according to the trailer manufacturer’s recommendation.
●All trailer lights work as required by law.
●All lights work each time you connect them.
●The trailer ball is set at the proper height for the coupler on the trailer.
●The trailer is level when it is hitched.
