Weight limits
Check the allowable towing capacity, GVM (Gross Vehicle Mass),
MPAC (Maximum Permissible Axle Capacity), and permissible draw
bar load before towing. (P. 562)
Towing hitch/bracket
Lexus recommends the use of the Lexus hitch/bracket for your vehicle.
Other products of a suitable nature and comparable quality may also be
used.
To prevent an accident
The handling of the vehicle will feel different when towing a trailer.
Beware of the 3 most common causes of towing-related accidents:
driver error, excessive speed, and overloading.
Trailer towing (vehicles with a towing package)
The strain of towing a trailer will have a negative impact on the running
performance, handling, fuel consumption and endurance of your vehicle.
Use the vehicle features in the correct manner and operate the vehicle
with care for safer driving and optimal comfort. Damage and/or malfunc-
tions that occur as a result of towing performed for commercial purposes
are not covered by the Lexus warranty.
Ask your local authorized Lexus dealer or repairer, or another duly qual-
ified and equipped professional for further details before towing, as there
are additional legal requirements in some countries.

Total trailer weight and permissible drawbar load
Total trailer weight
Weight of the trailer itself plus the
trailer load should be within the
maximum towing capacity.
Exceeding this weight is danger-
ous. (P. 562)
When the total trailer weight is
greater than the vehicle weight,
we recommend the use of a fric-
tion stabilizer (sway control
device).
Permissible drawbar load
Allocate the trailer load so that the drawbar load is greater than 25 kg (55.1
lb.) or 4% of the towing capacity. Do not let the drawbar load exceed the
indicated weight. (P. 562)
Information tag (manufacturer’s label)
Gross vehicle mass
The combined weight of the driver, passengers, towing hitch, total curb
mass and drawbar load should not exceed the gross vehicle mass by more
than 100 kg (220.5 lb.). Exceeding this weight is dangerous.
Maximum permissible rear axle capacity
The weight borne by the rear axle should not exceed the maximum permis-
sible axle capacity by 15% or more. Exceeding this weight is dangerous.
The values for towing capacity were derived from testing conducted at sea
level. Take note that engine output and towing capacity will be reduced at
high altitudes.

Tire information
Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) greater
than the recommended value when towing. (P. 570)
Increase the air pressure of the trailer tires in accordance with the total trailer
weight and according to the values recommended by the manufacturer of your
trailer.
Break-in schedule
Lexus recommends that vehicles fitted with new power train components should
not be used for towing trailers for the first 800 km (500 miles).
Safety checks before towing
Check that the maximum load limit for the towing hitch/bracket hitch ball is not
exceeded. Bear in mind that the coupling weight of the trailer will add to the
load exerted on the vehicle. Also make sure that you will not be towing a load
that exceeds the maximum permissible axle capacity.
Ensure that the trailer load is secure.
Supplementary outside rear view mirrors should be added to the vehicle if the
traffic behind cannot be clearly seen with standard mirrors. Adjust the extend-
ing arms of these mirrors on both sides of the vehicle so that they always pro-
vide maximum visibility of the road behind.
Maintenance
Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight burden placed on the vehicle compared to nor-
mal driving.
Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).
NOTICE
When the rear bumper strengthening material is aluminum
Ensure the steel bracket part does not come directly in contact with that area.
When steel and aluminum come into contact, there is a reaction similar to cor-
rosion, which will weaken the section concerned and may result in damage.
Apply a rust inhibitor to parts that will come in contact when attaching a steel
bracket.
