■Trailer tongue load
●A recommended tongue load varies in accordance with the types
of trailers or towing as described below.
● In order to ensure the recommen ded values shown below, the
trailer must be loaded by referring to the following instructions.
The trailer cargo load should be distributed so that the tongue
load is 9 to 11 % of the total trailer weight, not exceeding 650 lb.
(294 kg). (Tongue load/Total trailer weight 100 = 9 to 11 %)
If the gross trailer weight is ov er 2000 lbs. (900 kg), it is neces-
sary to use a sway control de vice with sufficient capacity.
If the gross trailer weight is ov er 5000 lbs. (2268 kg), it is neces-
sary to use a weight distributing hitch with sufficient capacity.
If using a weight distributing hitc h when towing, keep your vehicle
level with the ground.
The total trailer weight and tongue load can be measured with
platform scales found at a highway weighing stations, building
supply companies, trucking co mpanies, junk yards, etc.

Towing a trailerContact your Lexus dealer for furt her information about additional
requirements such as a towing kit etc.
Hitch
Trailer hitch assemblies have differen t weight capacities established by
the hitch manufacturer. Ev en though the vehicle may be rated for towing
a higher weight, the operator must never exceed the maximum weight
rating specified for the trailer hitch.
Towing related termMeaning
Towing capacity
The maximum allowable gross trailer
weight. Towing capacity is calculated con-
sidering the base vehicle with necessary
vehicle equipment and occupants. Addi-
tional optional equipment, passengers and
cargo in the vehicle will reduce the towing
capacity, gross trailer weight includes the
trailer, cargo and necessary equipment for
towing.
Tongue loadThe load placed on the trailer hitch ball.

■Break-in schedule
Lexus recommends that you do not use a new vehicle or a vehicle with any new
power train components (engine, transmission, differential, wheel bearings, etc.) to
tow a trailer for the first 500 miles (800 km) of driving.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide”, “Owner’s Manual
Supplement” or “Scheduled Maintenance”.)
●Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.
CAUTION
■Trailer towing precautions
●Follow all the instructions described in this section. Failure to do so could cause
an accident resulting in death or serious injury.
●Exceeding the towing capacity, GVWR, GCWR and GAWR can cause an acci-
dent resulting in death or serious personal injuries.

CAUTION
■To avoid accident or injury
●The total trailer weight (trailer weight plus the weight of cargo) must not exceed
6500 lb. (2948 kg).
●If a trailer and cargo weigh over 2000 lbs. (900 kg), use a sway control device of
sufficient capacity.
●If the gross trailer weight is over 5000 lbs. (2268 kg), it is necessary to use a
weight distributing hitch with sufficient capacity.
●If using a weight distributing hitch when towing, keep your vehicle level with the
ground.
●The gross combined weight (sum of your vehicle weight plus its load and the total
trailer weight) must not exceed 13100 lb. (5492 kg).
●Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue load capacities.
●Never load more weight in the back than in the front of the trailer. About 60 % of
the load should be in the front half of the trailer, and the remaining 40 % in the
rear.
●The tow hitch receiver installed on your vehicle must never be used on another
vehicle.
●Do not exceed 45 mph (72 km/h) or the po sted towing speed limit, whichever is
lower. A instability (swaying) of the towi ng vehicle-trailer combination increases
as speed increases, exceeding 45 mph (72 km/h) may cause loss of control.

GX460_U.S.A. (OM60E69U)
Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of handling
control.
■ Wheel selection
When replacing wheels, care should be taken to ensure that they
are equivalent to those removed in load capacity, diameter, rim
width, and inset
*.
Replacement wheels are available at your Lexus dealer.
*: Conventionally referred to as “offset”.
Lexus does not recommend using:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
● Lexus wheels with after market chrome plating
■ Aluminum wheel precautions
●Use only Lexus wheel nuts and wr enches designed for use with
your aluminum wheels.
● When rotating, repairing or changi ng your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● When balancing your wheels, us e only Lexus genuine balance
weights or the equivalent. If clip-on balance weights are being
used, use a plastic or rubber hammer to install the weight.
